Opis:
Forty-seven left-behind children (LB) and 40 non-left-behind children (NL) in rural China were interviewed to evaluate moral, conventional, and personal violations by providing judgments and justifications. The results suggested that both LBs and NLs differentiate the rules of moral, conventional and personal domains. However, there are some differences: 1. The NL considered it acceptable to commit a personal infraction when there was no rue prohibiting it, while the LB considered it wrong; 2. The younger male LBs were more willing to accept situations without moral psychological rules, compared with younger female LBs, older male LBs, and younger male NLs. Age, sex differences were also found. The one out of our expectation is that younger males considered it more acceptable to commit a personal infraction than older males did and believed it all right if there was no explicit rule on it. Meanwhile, in providing reasons to support their judgments or evaluations, the findings revealed that: 1. More often LBs referred to social conventional reasoning even when evaluating moral and personal rules and violations, especially on personal issues; 2. LBs used more justifications of punishment and fewer justifications of personal growth. The implications of the results of the study for children’s moral development and education, especially for LBs, are discussed.

Opis:
A linear Support Vector machine classifier is proposed in this paper. In such SVM architectures based on multiplying laws the main building blocks are multipliers. We propose in this paper multiplying and weighting cells, developed by using a model consisting of a compound of two inverse non-linear functions. This procedure is suitable for VLSI implementation because it permits the use of simple nonlinearized standard log-domain or DA cells that compensate each other nonlinearities to obtain an extended domain of operation. Current-mode ELIN (externally linear internally nonlinear) design is used for its low voltage, low power and high speed characteristics. The resulted parallel-serial classifier was simulated taking into account real parameters of transistors in BICMOS technology.

We compare them with the classical altitude inequality and altitude formula, and we give another characterization of locally Jaffard domains, and domains satisfying absolutely the altitude inequality (resp., the altitude formula). Then we study the extensions R ⊆ S where R satisfies the corresponding condition with respect to S (Definition 3.1). This leads to a new characterization of integral extensions.

Partial discharge (PD) measurement results with particular consideration of time domain and frequency domain analysis of pulses generated by PD model sources are presented in the paper. Three different PD generation model sources are selected for the research: surface type, point to point and multi-point to plate. All measurements are proceeded under laboratory conditions using electrical method of a PD detection, according to the IEC60270 standard. Various amplitude and power density spectrum descriptors are proposed, as well as PD source type identification abilities on grounds of the selected descriptors are considerated. Electrical power transformers on-line PD detection and evaluation systems improvement and development are the main purpose of the presented research. Laboratory experiment results gives a solid base for further research focused on verification of the proposed methodology on a real life apparatus.

Opis:
By conducting an examination of the mapping process in metaphor comprehension, this article suggests that a set of superficially different metaphors can be considered to be isomorphic to an underlying generic metaphor. In other words, a set of seemingly different metaphors with different domains can be categorized under a single generic metaphor. The generic metaphor is in the general form of X is in some kind of semantic relationship with Y. When this generic metaphor is realized in specific-level forms, a number of metaphors are produced which are isomorphic to each other, although their domains could be completely different in appearance. In other words, there is a deep homogeneity among a set of concretely different metaphors. A generic metaphor can be seen as a semantic frame for all specific metaphors that are isomorphic to it. Since base and target domains of a given metaphor can be very different in terms of concrete features, the mapping of the base into the target must be mediated by the domain of its underlying generic metaphor.

Opis:
Three monoclonal antibodies specific to the central cell-binding and the C- and N-terminal domains of fibronectin (FN) were used to test antigenic epitope accessibility on human plasma and cerebrospinal fibronectins. In the plasma group, the mean N-terminal FN domain immunoreactivity was about one fourth that of the cell-binding and C-terminal domains, whereas in cerebrospinal fluid they were nearly equal. In the presence of 0.5-6 M urea N-terminal domain immunoreactivity in the plasma increased 3-6-fold, but it decreased 0.7-3-fold in the cerebrospinal fluid. Analysis of fibronectin domain immunoreactivities of the cell-binding and N-terminal domains by a panel of specific monoclonal antibodies may reveal N-terminal fibronectin domain accessibility for reaction with biological partner ligand(s) and/or processes in which FN could be implicated. Such determinations may have important clinical implications.

Opis:
To date canonical size for physical objects has been exclusively investigated in the visual domain and termed canonical visual size. As the visual and haptic modalities are interconnected in object processing, we have investigated if canonical size occurs in the tactile domain, namely, in embossed drawings made by sighted adults when blindfolded. 17 participants were asked to draw 16 objects of 8 different ranks of physical size. In the visual domain, they drew on sheets of paper, and in the tactile domain, they drew (when blindfolded) on special plastic sheets for embossed graphics haptically controlling the performance with hands. In both the visual and the tactile domain the size of drawings increased linearly with the logarithm of the physical size of real-world objects indicating occurrence of canonical size effect in both domains. Our findings demonstrated that canonical size is not only visual in character but that it is also revealed in a haptic drawing task. It suggests that spatial images (at least visual and tactile) are shared instead of being unimodal in nature.

Opis:
Cybersquatting is defined as the practice of registering internet domains that include individual designations of an enterprise, for instance its trademark. This action may be considered both as an unfair business practice as well as an infringement of laws protecting the trademarks. Nowadays, as the Internet is getting more and more popular on a massive scale, cybersquatting is posing a threat that becomes bigger and bigger - not only for each and every enterprise, regardless of its size or recognition, but also for people engaged in public activities. Domain piracy can be committed by a legal person as well as a natural one. Most often the motive behind cybersquatters’ actions is the desire to gain money from reselling an attractive domain or blocking off rival entrepreneurs from market access.

Opis:
The position controller cascade is widely used in standard industrial controllers. Its controller parameterisation is commonly performed by either applying basic tuning rules or by carrying out not comprehensible design automatisms.In this paper an alternative approach to parameterise the cascade in one step is presented. It bases on established methods within the field of optimisation research specifically the so-called simulation-based optimisation (SBO), which can also handle non-linear models and various constrains. Own research showed, that criteria in the time domain as well as in the frequency domain are suitable optimisation criteria. However, both types have individual advantages and disadvantages. Therefore, in this research, selected representatives from both types were combined as new multi-objective optimisation criteria and investigated according to their performance. Investigations were performed for a test rig model (third order transfer function plus dead time and friction).The paper presents fundamentals of the SBO and a description of the optimisation criteria, obtained results as well as their verification on the test rig. Also, the derived controller parameterisations are compared to the integrated tuning automatism.

Opis:
The physical phenomenon considered in the paper deals with flow in a lake, which contains one or several islands. The flow is generated by rivers, their inlets and outlets being distributed on the shoreline of the lake. The problem to be solved consists in determination of the velocity field - in the domain bounded by the shorelines of the lake and the islands. In fact, it is attempted to arrive solely at an estimation of the field. Consequently, a rather simple physical model of the phenomenon, as well as its simple mathematical description has been applied. In particular, plane, irrotational and steady flow of ideal liquid has been introduced, the inlets and outlets of the rivers being simulated by sources and sinks. Hence, the problem reduces to determination of a complex function, representing the complex velocity field, which satisfies the impermeability condition on all contours representing the shorelines, the field being generated by the singularities already mentioned. Unfortunately, the so formulated problem is "overconditioned" or "too stiff", what means that the impermeability condition on the outer contour cannot be satisfied. Nevertheless, we arrived at a simple method for circumventing this obstacle, the payoff consisting in some modification of this contour. We had this particular modification in mind, applying the word "approximate" in the title of the paper. The paper contains results - in the form of streamline patterns - for lakes containing from 1 to 3 islands. In the relevant figures the distances between the given and the modified exterior contours can be seen distinctly - allowing the reader to draw conclusions, whether the errors due to the modifications are admissible or not. Of course, it depends anyway on the point of view of the user of the results.

The measurements of the recoil curves for the die-upset Nd-(Fe, Co)-B based magnets from different points on the magnetization and demagnetization curves have been carried out by means of the LakeShore vibrating sample magnetometer in an applied magnetic fields up to 2 T. From the recoil curves the so-called Wohlfarth's remanence relationship has been derived. From this it was deduced that the magnetic interaction existing between the magnet grains has a dipolar nature. The existence of the magnetic interaction has been confirmed by magnetic domain observations by using the magnetic force microscopy (MFM). In the area of interaction domains there is the fine scale magnetic contrast resulting from the dipolar interaction between neighboring grains.
Za pomocą magnetometru wibracyjnego firmy LakeShore wyznaczono krzywe powrotne dla spęczanych magnesów Nd-(Fe, Co)-B w polu magnetycznym do 2 T. Na podstawie krzywych powrotnych wyznaczono zależność remeanencyjną Wohlfartha. Z zależności tej wynika, że oddziaływania magnetyczne pomiędzy ziarnami to dalekozasięgowe oddziaływania dipolowe. Obecność tych oddziaływań została potwierdzona przez obserwację struktury domenowej za pomocą mikroskopu sił magnetycznych (MFM). Oscylacyjne zmiany kontrastu, występujące w obszarach zbliżonych do wielkości ziaren, świadczą o istnieniu uporządkowania magnetycznego w tych obszarach, które jest wynikiem oddziaływania dipolowego między sąsiednimi ziarnami.

Opis:
We compare three different approaches to parsing into syntactic, bilexical dependencies for English: a ‘direct’ data-driven dependenci parser, a statistical phrase structure parser, and a hybrid, ‘deep’ grammar-driven parser. The analyses from the latter two are postconverted to bi-lexical dependencies. Through this ‘reduction’ of All three approaches to syntactic dependency parsers, we determine empirically what performance can be obtained for a common set of dependenci types for English; in- and out-of-domain experimentation ranges over diverse text types. In doing so, we observe what trade-offs apply along three dimensions: accuracy, efficiency, and resilience to domain variation. Our results suggest that the hand-built grammar in one of our parsers helps in both accuracy and cross-domain parsing performance. When evaluated extrinsically in two downstream tasks – negation resolution and semantic dependency parsing – these accuracy gains do sometimes but not always translate into improved end-to-end performance.

These are the problems of data integration (DI) and statistical estimation for small domains (SDE).On the other hand, attempts to determine relationship between these two groups of methods were undertaken. Given convergence of the objectives of both SDE and DI, that is: striving to increase efficiency of the use of existing sources of information, simulation study was conducted. It was aimed at verifying the hypothesis of synergies referring to combined application of both groups of methods: SDE and DI.

Opis:
The paper investigates the impact of a precise ship domain shape on the size of collision avoidance manoeuvres. The considered collision avoidance manoeuvres include both course and speed alterations. Various ship domains are compared with their polygonal approximations, which vary in the number of points of a domain contour and placement of these points. The best of all considered approximations is determined in the course of simulation experiments performed for head-on, crossing and overtaking situations. The chosen number and placement of contour points combine precision of domain approximation with reasonable computational time.

Opis:
The aim of the article is to conduct a semantic analysis of Polish interjections. The collected data consist of words (200 forms), which were qualified as an interjecion in the National Corpus of Polish and in the Uniwersalny s³ownik jêzyka polskiego. The article consists of four chapters. The first part provides a short introduction to the subject matter related to interjections and includes a short summary of the views and opinions concerning their semantic structure. The author briefly describes methods and the conception of the meaning, which are used in the article (cognitive semantics). The third chapter provides a semantic analysis of interjections. It consists of the description of characteristic central domains, in frames of which interjections are conteptualised (feelings, movements, sounds, scripts and will) and presents characteristic features of the domain matrixes of interjections. Finally, the author summarizes the research results.

Opis:
This article describes a parallel implementation of a ray tracing algorithm in a heterogeneous anisotropic geological medium. The shortest path method, which was used for calculations, can give ray path and travel time of seismic wave propagation even for a random and discontinuous velocity field. The high precision required in such calculations was obtained by employing a dense computational grid. This led to a significant increase in the computational effort of the algorithm. The procedure was parallelized using domain decomposition. The results show that the parallel performance of the ray tracing procedure strongly depends on the assumed geological method and differs between media with and without anisotropy of seismic wave propagation.

Opis:
Problem of building barriers moisture is a well known phenomenon for almost all users of the buildings. Its presence is inevitable in moderate climate and its balanced states are acceptable. On the other hand, extended values of moisture are disadvantageous and may be caused by many factors like water vapor condensation inside the barriers, capillary rise of ground water, rainwater, inundations or sanitary systems failures. This phenomenon is also a factor which limits the object functionality both from the construction and sanitary-hygienic reasons. Extended moisture content problem is particularly visible in the historical buildings which were set up without the suitable horizontal water-proof isolations. In this cases, ground water has the unlimited access to the groundwork and then, due to the capillary forces to the internal parts of the walls. Increased amounts of water lead to the material structure destruction by melting and thawing processes during winter season, wood decay, and accelerated corrosion of steel reinforcement elements and crystallization of dissolved salts in transported water. Also it should be mentioned here, that indirectly, water negatively influences the indoor environment providing good conditions for harmful microorganisms and mould development which may consequently run to the respiratory system diseases, infections, allergies, eyes and skin irritations. All above presented negative consequences of water presence inside the building envelopes are the reason for constant development moisture detection techniques.
Zjawisko zawilgocenia przegród budowlanych jest znane w zasadzie wszystkim użytkownikom obiektów budowlanych. Występowanie tego zjawiska jest praktycznie nie uniknione w warunkach klimatycznych w jakich znajduje się Polska. Jego zrównoważona obecność polegająca na ciągłym pochłanianiu wilgoci i jej odparowywaniu jest jak całkowicie akceptowalna. Szkodliwym jest natomiast zjawisko nadmiernej zawartości wilgoci, które może być wywołane wieloma czynnikami do których zaliczamy kondensację pary wodnej wewnątrz przegrody, podciąganie kapilarne wód gruntowych, wody rozbryzgowe z deszczy, wody powodziowe czy też awarie instalacji sanitarnych. Zjawisko powyższe jest niekorzystne z punktu widzenia budowli i jest czynnikiem ograniczającym funkcjonalność obiektu zarówno ze względów konstrukcyjnych, jak i higieniczno-sanitarnych. Problem nadmiernej zawartości wody w murach jest szczególnie widoczny w budynkach historycznych wznoszonych bez zastosowania właściwych izolacji poziomych. Wówczas woda gruntowa posiada nieograniczony dostęp do fundamentów budynku, a następnie przy udziale sił kapilarnych do wnętrza murów. Nadmierna ilość wody w zewnętrznych przegrodach budowlanych prowadzi do zniszczenia struktury materiału poprzez wielokrotne procesy zamarzania i rozmarzania w okresie zimowym, rozkład drewna, przyspieszoną korozja stalowych elementów zbrojeniowych oraz krystalizacja soli rozpuszczonych w transportowanej wodzie. Istotnym problemem jest również fakt, że woda pośrednio negatywnie oddziałuje na środowisko wewnętrzne pomieszczeń, przyczyniając się tym samym do rozwoju szkodliwych mikroorganizmów oraz grzybów pleśniowych. Może w konsekwencji przyczyniać się do chorób dróg oddechowych, infekcji, alergii oraz podrażnień oczu i skóry. Przedstawione powyżej negatywne skutki obecności wody w przegrodach budowlanych są podstawą do rozwoju i ciągłego opracowywania i udoskonalania technik detekcji wilgoci w przegrodach budowlanych. W niniejszym artykule przedstawiono możliwość przeprowadzenia badań in-situ przy zastosowaniu techniki pomiarowej TDR (Time Domain Reflectometry). Technika ta od wielu lat stosowana była do pomiarów wilgotności ośrodków gruntowych. Od początku XXI wieku trwały prace nad zastosowaniem techniki TDR do oceny zawilgocenia twardszych od gruntu materiałów i przegród budowlanych. Jednak inwazyjny charakter metody w większości przypadków uniemożliwiał jej praktyczne wykorzystanie lub był przyczyną wielu problemów technicznych. W ramach części badawczej artykułu przedstawiono pomiary wilgotności muru z cegły ceramicznej pełnej pokrytej warstwą tynku wapiennopiaskowego. Badany obiekt znajduje się na Lubelskiej starówce i jest to ściana bramy przy ul. Ku Farze. Jest to przegroda dotknięta zjawiskiem podciągania kapilarnego wynikającego z braku właściwych izolacji poziomych. Badania przeprowadzono w trzech terminach pomiarowych przy pomocy opracowanych na Politechnice Lubelskiej sond powierzchniowych TDR, umożliwiających bezinwazyjne pomiary wilgotności. W celu wykonania pomiarów, badaną przegrodę podzielono na charakterystyczne fragmenty tworzące siatkę pomiarową o określonych wymiarach. W trakcie eksperymentu w charakterystycznych punktach przegrody umieszczano czujnik i odczytywano parametry dielektryczne ośrodka, automatycznie przeliczając je na wilgotność objętościową. Wyniki przeprowadzonych badań naniesiono na siatkę pomiarów różnicując je kolorami w zależności od odczytanej wilgotności. Rezultatem powyższych zabiegów było uzyskanie tzw. map wilgotności przegrody budowlanej w trzech różnych terminach pomiarowych. Przedstawione w artykule mapy wilgotności potwierdzają fakt podwyższonej wilgotności przegrody i jednocześnie pozwalają na ukazanie jego rozkładu w pionie oraz poziomie. Przeprowadzone badania wyraźnie ukazują, że badana przegroda wykazuje nadmierną wilgotność w swych dolnych partiach, natomiast wyższe partie są nieco mniej wilgotne. Świadczy to o tym, że przyczyną nadmiernego zawilgocenia są wody gruntowe podciągane kapilarnie do wewnątrz struktury materiału. Wyniki badań przedstawione w artykule dowodzą skuteczności rozwijanych powierzchniowych sond TDR do bezinwazyjnego pomiaru wilgotności materiałów i przegród budowlanych oraz wskazują na przyczyny tego zjawiska w obiektach rzeczywistych.

contextual domain restriction
Opis:
The paper presents a proof-theoretic semantics account of contextual domain restriction for quantified sentences in a fragment of English. First, the technique is exemplified in the more familiar first-order logic, and in its restricted quantification variant. Then, a proof-theoretic semantics for the NL fragment is reviewed, and extended to handling contextual domain restriction. The paper addresses both the descriptive facet of the problem, deriving meaning relative to a context, as well as the fundamental aspect, defining explicitly a context (suitable for quantifier domain restriction), and specifying what it is about such a context that brings about the variation of meaning due to it. The paper argues for the following principle (the context incorporation principle, CIP): for every quantified sentence S depending on a context c, there exists a sentence S′, the meaning of which is independent of c, s.t. the contextually restricted meaning of S is equal to the meaning of S′. Thus, the effect of a context can always be internalized. The current model-theoretic accounts of contextual domain restriction do not satisfy CIP, in that they imply intersection of some extension with an arbitrary subset of the domain, that need not be the denotation of any NL-expression.

An analytical time domain solution is developed to model the dynamic response of a tool during a simple turning operation. The time domain solution developed in this paper relies on the superposition principal under the linear assumption to construct the time response of single mode, single degree of freedom cutting tool. The results from the analytical solution are compared with those generated using numerical time domain simulations and it is found that the two solutions converge as the time step used in the numerical simulation decreases.

The article aims to analyze the entities in the domain name registration system in Poland in the light of the provisions of the NIS-2 Directive. The European Union NIS-2 Directive replaces the original network and information systems (NIS Directive) from 2016, to account for the changing character of the digital society and the increased need for improved cybersecurity. Quoting the directive: „The NIS Directive is not sufciently clear when it comes to the scope for operators of essential services and its provisions do not provide sufcient clarity regarding national competence over digital service providers”. The legislation also imposes specific obligations on providers of DNS services in the EU, including registries and registrars, to maintain complete and accurate registration data and share this data in a timely manner to „legitimate access seekers”1. The article attempts to determine the entities involved in the domain name registration system and the mutual correlations.

Opis:
The debate over teaching evolution in the US is often construed in terms of a metaphorical war. As the conflict first drew national attention with the 1925 trial of John T. Scopes in Tennessee, and again returned to Tennessee in 2012 with the passage of a science education bill, we believe that analyzing the language used to describe these events will improve understanding of how this conflict is communicated. Our analysis draws on the conceptual metaphor theory proposed by Lakoff and Johnson (1980a) and suggests that participants on either side of the debate view the conflict according to a “just war scenario” (1991). This construal intensifies the moral weight of the conflict, making compromise and dialogue more difficult. The introduction outlines the history of the conflict, which is followed by a description of research conducted to date. section 3 explains the questions addressed in the paper, section 4 presents the conceptual metaphor theory, and section 5 describes the materials analyzed. The results are divided into two parts: section 6.1 looks at articles from the 1920s; section 6.2 looks at articles from 2012. Discussion of the results can be found in section 7 and is followed by ideas for future research.

Opis:
The paper reports results of an analysis concerning the infuence of a computational domain discretization method on the numerical stability of a model as well as the calculation error. The topology of a packed bed of a granular material consisting of granules contacting tangentially in one point makes the modeling of heat and mass transfer due to the fluid flow in such a domain a chalenging task. Therefore, the contribution of this paper constitutes a summary of discretization methods with discussion and guidelines allowing one to effectively select the most favourable method dedicated to discretization of the domain. The validation using Particle Image Velocimetry and evaluation of the impact of inflow velocity on the experimental and numerical research results are also presented in the paper.

Opis:
This paper aims at reading Shakespeare’s play Othello through the prism of cognitive linguistics, more specifically through the lens of conceptual metaphor theory. Metaphorical linguistic expressions that have animals in the source domain are extracted from the play so that matters of race and gender could be discussed from below the level of words, where cognition and conceptualization occur. As the analysis of metaphorical linguistic expressions progresses, the representation of evil will appear to be intertwined with the perception of gender and race, becoming yet another cognitive interest of the literary text. While African American studies, critical race theory, post-colonial studies, Marxist and feminist readings have immensely benefitted the comprehension of the play, conceptual metaphor theory promises to explore and explain how a derogatory perception of “Other” emerges in Othello, along with the offensive language that embodies it. Additional relevant concepts that account for the disturbing pace of the plot towards the catastrophe and tragic end are indoctrination and manipulation. These are specifically related to Iago’s perceptual playing around with unstable and highly sensitive notions such as race, gender, fallen virtue, degraded and demonic human nature, which he presents through disquieting mental images conveyed by powerful metaphorical language.

Opis:
Hsp70s are chaperone proteins that are conserved in evolution and present in all prokaryotic and eukaryotic organisms. In the archaea, which form a distinct kingdom, the Hsp70 chaperones have been found in some species only, including Methanosarcina mazei. Both the bacterial and archaeal Hsp70(DnaK) chaperones cooperate with a GrpE co-chaperone which stimulates the ATPase activity of the DnaK protein. It is currently believed that the archaeal Hsp70 system was obtained by the lateral transfer of chaperone genes from bacteria. Our previous finding that the DnaK and GrpE proteins of M. mazei can functionally cooperate with the Escherichia coli GrpE and DnaK supported this hypothesis. However, the cooperation was surprising, considering the very low identity of the GrpE proteins (26%) and the relatively low identity of the DnaK proteins (56%). The aim of this work was to investigate the molecular basis of the observed interspecies chaperone interaction. Infrared resolution-enhanced spectra of the M. mazei and E. coli DnaK proteins were almost identical, indicating high similarity of their secondary structures, however, some small differences in band position and in the intensity of amide I' band components were observed and discussed. Profiles of thermal denaturation of both proteins were similar, although they indicated a higher thermostability of the M. mazei DnaK compared to the E. coli DnaK. Electrophoresis under non-denaturing conditions demonstrated that purified DnaK and GrpE of E. coli and M. mazei formed mixed complexes. Protein modeling revealed high similarity of the 3-dimensional structures of the archaeal and bacterial DnaK and GrpE proteins.

Opis:
Many agrotourist farms use the potential of websites to distinguish their offer from others to attract as many guests as possible. However, maintaining a website is connected with a range of costs, e.g. registering the domain and the hosting package. Searching for cost savings, the owners of agrotourist farms often face the dilemma of choosing between a payable website and its free equivalent. The aim of this article is to analyse internet addresses as regards their type and potential, both informative and marketing. The surveys were carried out on a set of 1,121 websites. The analysis included domain names (main names) as well as domain extensions, paying special attention to type and indicating sub-domains at the same time. Division into payable and free was looked for as well. In conclusion, it is shown that the owners of agrotourist farms mostly use national domains, choosing addresses in functional, regional or European domains less frequently. Moreover, they relatively rarely use addresses created on free services. In their place, they choose free sub-domains often created in the domain of the provider hosting a regional (informative) portal or another.

Opis:
The aim of this paper is the cognitive definition and placement of the human resource management domain within social systems, with a particular focus on the enterprise. Approaches taken to date are not sufficiently systematic. This creates a peculiar 'jungle of theories' where contributions and fashions reign supreme. The basis for defining the human resource management subsystem is the determination of a key value - the staff's capacity to realize the objectives of the enterprise as well as fundamental processes shaping that capacity. It is around these values and processes that other activities and processes, factors (objects), institutions, and social structures develop. Together, they account for the human resource management subsystem in its broader (classical) and narrower (specialized) sense. This provides the teleological and material foundations for furthering human resource studies.

Periodic function – it is a proposition of a new definition – has as its domain the multiplicative group T = {z ∈C : |z| = 1} of complex numbers with module one. Therefore the graph of the function f : T → R lies on the cylinder T × R, and so the graph of cosine function is the ellipse (math formula)

Opis:
This brief essay is an exploration of how the public domain came to achieve its place as a focus of attention, how it shaped a generation of scholars, and why public interest might be a more salient construct for thinking about how to foster a public-directed system of global knowledge governance. In short, this is the story of the rise, fall, and reincarnation – as public interest – of the public domain.

Opis:
Problem zbyt małej liczby obserwacji w próbie, reprezentującej określoną domenę populacji, może być rozwiązany między innymi poprzez zastosowanie takich estymatorów, które do szacowania parametrów w określonej supopulacji (małym obszarze, domenie) mogłyby wykorzystać informacje o innych jednostkach w próbie, które pochodzą spoza określonej części populacji. Jedna z metod estymacji dla małych domen zwana estymacją syntetyczną zakłada, że rozkład w badanej małej domenie jest identyczny z rozkładem całej populacji. Założenie to pozostaje zazwyczaj niespełnione, zwłaszcza w przypadku specyficznych domen, co skutkuje dużymi błędami estymacji. Autorzy przedstawiają propozycję dwuetapowego procesu estymacji. W pierwszym etapie za pomocą sieci neuronowych typu SOM oraz za pomocą metody klasyfikacji k-średnich określa się podobieństwa jednostek należących do małej domeny do jednostek z pozostałej części próby. Drugim krokiem jest wykorzystanie w estymacji, za pomocą odpowiednio skonstruowanych wag, informacji tylko z tych domen, które są podobne do badanej małej domeny. Autorzy przedstawiają rezultaty zastosowania podanej procedury w analizie branży budowlanej na podstawie wyników reprezentacyjnego badania małych i średnich przedsiębiorstw. Podjęli także próbę oszacowania błędów tak zmodyfikowanej metody estymacji syntetycznej.
The problem of a too small number of observations of a sample, representing a defined domain of a population may be solved inter alia thanks to the application of estimators which would use information about other components of the sample (derived from outside the defined part of the population) to estimate parameters in a given subpopulation (small area, domain). One of estimation methods for small domains - the synthetic estimation - assumes, that the distribution of the studied small domain is identical with the distribution of the whole population. This assumption remains usually unfulfilled, in particular in case of specific domains, what results in large estimation errors. The authors present a proposition of two-stage estimation process. In the first stage, using the SOM-type neural networks and using the k-means classification method the similarity of components belonging to the small domain with the components belonging to the remaining part of the sample is determined. The second step consists in using the information only from those domains, which are similar to the studied small domain with the help of appropriately construed weights. Authors present the results of the above procedure in the analysis of the building industry on the basis of a representative study of small and medium-sized enterprises. They have also undertaken an attempt to estimate the errors of the synthetic estimation method modified in such a way.

Opis:
In many statistical surveys one faces the problem of insufficient number of sample observations to make reliable inference about a given population domain of interest (small area). One possible solution, which has been discussed in statistical publications consists in applying estimators, which will be able to combine sample information from the given domain with information about sample units representing other domains. Synthetic estimation technique is particularly efficient, if the distribution ot the variable ot interest is the same in the given domain and in the entire population. When this assumption is far from being met, one can obtain, as a consequence, large estimation errors. Using modified synthetic estimator requires an application of a two-stage estimation procedure. The first stage consists in applying some distance measures in order to identify the degree of similarity between the sample units from the investigated domain and sample units representing other domains. In the second stage, those units, which turned out to be similar to units from the domain of interest, are used to provide sample information with specially constructed weights. A method of establishing weights is one of the crucial factors in using MES estimator. Author presents results of Monte Carlo analysis of the efficiency of MES estimator using different weights.

Jedna z metod estymacji dla małych domen zwana estymacją syntetyczną sprawdza się przy założeniu, że rozkład (albo któryś z parametrów rozkładu) w badanej małej domenie jest identyczny z rozkładem całej populacji. Założenie to pozostaje zazwyczaj niespełnione, zwłaszcza w przypadku specyficznych domen, co skutkuje dużymi błędami estymacji. Zastosowanie zmodyfikowanego estymatora syntetycznego (MES) zakłada dwuetapowy proces estymacji. W pierwszym etapie za pomocą metod klasyfikacji lub badania podobieństw określa się podobieństwa jednostek należących do małej domeny do jednostek z pozostałej części próby. Drugim krokiem jest wykorzystanie w estymacji, za pomocą odpowiednio skonstruowanych wag, informacji tylko od tych jednostek, które są podobne do jednostek z małej domeny. Ważnym czynnikiem wpływającym na efektywność zmodyfikowanego estymatora syntetycznego jest dobór metod ustalania wag dla poszczególnych jednostek badanej zbiorowości. Autor przedstawia wyniki symulacyjnego badania efektywności estymatora MES przy zastosowanych różnych sposobach ustalania wag.

Opis:
Myosin 1C, the first mammalian single-headed myosin to be purified, cloned, and sequenced, has been implicated in the translocation of plasma membrane channels and transporters. Like other forms of myosin I (of which eight exist in humans) myosin 1C consists of motor, neck, and tail domains. The neck domain binds calmodulins more tightly in the absence than in the presence of Ca^(2+). Release of calmodulins exposes binding sites for anionic lipids, particularly phosphoinositides. The tail domain, which has an isoelectic point of 10.5, interacts with anionic lipid headgroups. When both neck and tail lipid binding sites are engaged, the myosin associates essentially irreversibly with membranes. Despite this tight membrane binding, it is widely believed that myosin 1C docking proteins are necessary for targeting the enzyme to specific subcellular location. The search for these putative myosin 1C receptors is an active area of research.

Opis:
PDZ domains are ubiquitous protein interaction modules that play a key role in cellular signaling. Their binding specificity involves recognition of the carboxyl-terminus of various proteins, often belonging to receptor and ion channel families. PDZ domains also mediate more complicated molecular networks through PDZ-PDZ interactions, recognition of internal protein sequences or phosphatidylinositol moieties. The domains often form a tandem of multiple copies, but equally often such tandems or single PDZ domain occur in combination with other signaling domains (for example SH3, DH/PH, GUK, LIM, CaMK). Common occurrence of PDZ domains in Metazoans strongly suggests that their evolutionary appearance results from the complication of signaling mechanisms in multicellular organisms. Here, we focus on their structure, specificity and role in signaling pathways.

Steganography is the approach for hiding any secret message in a variety of multimedia carriers like images, audio or video files. Whenever we are hiding a data, it is very important to make it invisible, so that it could be protected. A number of steganographic algorithms have been proposed based on this property of a steganographic system. This paper concentrates on integrating Tri way pixel value differencing approach and LSB matching revisited. The secret data embedded in images were images, text and audio signals so far. The proposed scheme has also come with the executable file as secret data. Also, the experimentation results show that, the important properties of a steganographic system such as imperceptibility, capacity of the carrier image and also resistance against the various steganalytic tools have also been achieved with this stego-system.

Opis:
Time analysis is a common approach for testing and detecting methods for the performance analysis of computer systems. In the article it is shown, that measuring and identifying performances based on a benchmark is not sufficient for the proper analysis of the computer systems behavior. The response time of the process is often composed of the execution of many subprocesses or many paths of execution. Under this assumption, it is presented, that both convolution and deconvolution methods can be helpful in obtaining time distributions and modeling of complex processes. In such a modeling the analysis of measurement errors is very important and was taken into consideration. The example of using the methods in buffering process is also discussed.

Opis:
In the paper a new implementation of a compact smart resistive sensor based on a microcontroller with internal ADCs is proposed and analysed. The solution is based only on a (already existing in the system) microcontroller and a simple sensor interface circuit working as a voltage divider consisting of a reference resistor and a resistive sensor connected in parallel with an interference suppression capacitor. The measurement method is based on stimulation of the sensor interface circuit by a single square voltage pulse and on sampling the resulting voltage on the resistive sensor. The proposed solution is illustrated by a complete application of the compact smart resistive sensor used for temperature measurements, based on an 8-bit ATxmega32A4 microcontroller with a 12-bit ADC and a Pt100 resistive sensor. The results of experimental research confirm that the compact smart resistive sensor has 1°C resolution of temperature measurement for the whole range of changes of measured temperatures.

The paper presents abilities and advantages following from the use of the harmonicbalance method for analysis of steady state of a multiphase system with switching devices on example of a matrix converter. Switching elements are modelled as resistances with step-wise variable parameters, what allows to describe the converter by a linear infinite set of equations. The analysis in frequency domain is presented on example of the one-periodic control strategy. External systems were also added using the Thevenin method approach. The numerical calculation results of a linear equations set were verified by the variable structure method in a time domain and the numerical convergence was confirmed. Furthermore, the exemplary complex system was analysed using the cascade method and current waveforms were obtained.

Opis:
The objective of this paper is to present a method for determining diurnal distribution of the intensity of effective non rainfall water flux. It was found that the application of TDR technique for the determination of diurnal dynamics of effective non rainfall water flux requires temperature correction of sensed volumetric moisture contents. Without temperature correction the error of estimated non rainfall water flux can be as much as 26%. In addition, the effect of temperature changes on the soil surface was determined in 0.5, 1, 2, 3, 4, and 5 hours periods. It was found that the intensity of effective non rainfall water flux was determined to the greatest extent by the rate of temperature drop during the period of 3 h preceding the non rainfall water flux determination. The agreement of non rainfall water flux calculated with the method proposed and that obtained by the collector was better for dew than for hoarfrost periods.

The aim of the study was to identify 8 – 9 and 9 – 10-year-old children’s knowledge of the following topic: target domain of the metaphorical mapping (JOY, SADNESS, LOVE, HATRED, FEAR) as well as childlike metaphorical accomplishments related to identification of similarities and diff erences between destination domain and source metaphor domain through the process of educational environment construction. In designed didactical intervention operations, research data resulted from participant observation, focus interview, and children’s production analysis (graphical visualization, paired-associate learning tasks and tests of unfinished tasks). Research findings show children’s preferences related to the translation of one metaphor discipline through another one as well as construction strategies related to children’s knowledge about the emotional aspect and feelings. Moreover, findings suggest the need for a broader understanding of educational environments in Polish educational culture.

Random lasers are unique systems where lasing occurs due to repetitive scattering in a disordered nanostructure. Previous descriptions of random lasing are numerous, however a full time-dependent theory that describes the introduction of gain directly from first principles is lacking in the literature. This paper will present an analytic self-consistent time-dependent theory of random lasing that contains the results from the well-known steady-state ab initio laser theory. This theory can also describe a number of temporal phenomena that have been observed in previous experiments and facilitates the incorporation of these devices into their envisioned practical applications.

Vasculature targeting agents have been tested as cancer therapeutics for the past few years. Such therapy could be accomplished using, for example, bifunctional (two-domain) peptides. RGD-4C-GG-D(KLAKLAK)2, a peptide designed by Ellerby and coworkers (1999) (full sequence: ACDCRGDCFCGGKLAKLAKKLAKLAK), binds selectively to αVβ3 integrin receptors expressed in tumor neovasculature and, after internalization, effectively induces apoptosis of endothelial cells. The aim of this study was to examine if RGD-4C-GG-D(KLAKLAK)2 would efficiently target cells, among them B16(F10), that overexpress αVβ3 receptors, and whether it would be suitable for therapeutic treatment of primary B16(F10) murine melanoma tumors. Thus, the peptide would target two distinct tumor compartments: that formed by endothelium of blood vessels and that made up of neoplastic cells. The therapeutic peptide was recognized and did induce apoptosis in B16(F10) cell line. Tumor growth inhibition was observed following direct intratumoral administration. However, cessation of peptide administration led to rapid tumor growth and death of the animals.

The study has revealed the presence of fibronectin (FN) fragments and a lack of intact FN in 72 seminal plasma samples. The FN fragmentation was examined by immunoblotting with a monoclonal antibody specific to the central cellular FN domain and was confirmed with a monoclonal antibody directed to the C-terminal domain of FN. Nine FN fragments between 60 and 200 kDa and five fragments of 60-150 kDa were identified in seminal plasma samples of normozoospermic and of terato-, oligoterato-, and oligoasthenoterato-spermic groups, respectively. The relative amounts of the 60, 90 and 100 kDa FN fragments were 2-3 times higher in seminal plasmas with abnormal semen characteristics than in the normozoospermic group. The results suggest that seminal plasma FN fragments may contribute to fertilization and the analysis of FN fragmentation may have a diagnostic value in andrological investigations.

Given the set of alternative routes, the initial and goal positions and velocities of own and target ships the output of the system is a ranking of all considered routes. This ranking enables the VTS operator to produce a proper route recommendation which is then sent to the navigators. The additional advantage of the system described here is its ability to support custom shape of ship domain.

Opis:
This paper presents a study of ships passing distances in coastal waters based on data from the AIS. Examinations are designed also to work towards the development of probabilistic domain that is an area in which the navigator is trying to keep free from other vessels. This article has been hypothesized for the distribution of ships passing distances from which you can build a probabilistic domain. The article summarizes the studies for three types of ships: tankers, passenger ships and cargo vessels and is comparing the shapes of domains for each of them in three situations: overtaking, crossing, vessels on the opposite courses. Studies were carried out in the Gulf of Pomerania.

Opis:
When observing the contemporary world, one cannot fail to notice that in many areas of life, not only in the personal lives of particular people, but also within the public and social aspects of human existence, conflict seems to be fairly omnipresent. This paper sets to analyse the discussed concept in the Polish language from two different perspectives. The first stage of the research deals with the analysis of the immediate linguistic vicinity of the notion of konflikt / conflict to search for the location of the aforementioned phenomenon within the Polish linguistic system. The aim of this research is to present what types of domains are employed to conceptualise konflikt / conflict. The analysis is based on the selected corpus data found in the Polish language. The second stage of the research comprises the analysis of 183 surveys containing two elements: the definitions of konflikt / conflict and the association maps referring to this concept created by students at the age of 16-24. The aim of this task is to search for the associations attached to the discussed phenomenon by young people, and the similarities and differences within the definitions suggested by them.

Opis:
The problem of insufficient number of sample observations representing a given population domain of interest (small area) can be solved by applying estimators, which will be able to combine sample information from the given domain with information about sample units representing other domains. Synthetic estimation technique assumes that the distribution of the variable of interest is the same in the given domain and in the entire population. This assumption, however, is rarely met, and as a result, one can obtain large estimation errors. Use of modified synthetic estimator requires an application of a two-stage estimation procedure. The first stage consists in applying some distance measures in order to identify the degree of similarity between the sample units from the investigated domain, and sample units representing other domains. In the second stage, those units, which turned out to be similar to units from the domain of interest, are used to provide sample information with specially constructed weights. Chosen distance measure is one of the crucial factors in using MES estimator. Author presents Monte Carlo analysis of the efficiency of MES estimator using different distance measures between sample units.
Problem zbyt malej liczby obserwacji w próbie, reprezentującej określoną domenę populacji, może być rozwiązany m. in. poprzez zastosowanie takich estymatorów, które do szacowania parametrów w określonej subpopulacji (małym obszarze, domenie) wykorzystują dodatkowe informacje z pozostałej części próby. Jedna z metod estymacji dla małych domen, zwana estymacją syntetyczną, zakłada, że rozkład w badanej małej domenie jest identyczny z rozkładem całej populacji. Założenie to pozostaje zazwyczaj niespełnione, zwłaszcza w przypadku specyficznych domen, co skutkuje dużymi błędami estymacji. Zastosowanie zmodyfikowanego estymatora syntetycznego (MES) zakłada dwuetapowy proces estymacji. W pierwszym etapie za pomocą metod klasyfikacji lub badania podobieństw określa się podobieństwa jednostek należących do małej domeny do jednostek z pozostałej części próby. Drugim krokiem jest wykorzystanie w estymacji, za pomocą odpowiednio skonstruowanych wag, informacji tylko od tych jednostek, które są podobne do jednostek z małej domeny. Ważnym czynnikiem wpływającym na efektywność zmodyfikowanego estymatora syntetycznego jest zastosowana miara odległości. Autor przedstawia wyniki symulacyjnego badania efektywności estymatora MES przy zastosowanych różnych miarach odległości do badania podobieństwa jednostek.

Opis:
The problem of insufficient number of sample observations representing a given population domain of interest (small area) can be solved by applying such estimators, which will be able to combine sample information from the given domain with information about sample units representing other domains. One small area estimation method, called synthetic estimation technique, assumes that the distribution of the variable of interest is identical in the given domain and in the entire population. This assumption, however, is rarely met, and as a result one obtains large estimation errors. In this paper a two-stage estimation procedure is suggested. The first stage consist in applying various classification methods to identify the degree of similarity between the sample units from the investigated domain and sample units representing other domains. In the second stage, those domains, which turned out to be similar to the domain of interest or sample units similar to units from domain of interest, are used to provide sample information with specially constructed weights. Authors present the results of the suggested procedure in an analysis of the continuing vocational training in construction industry based on a sample survey of enterprises. A bootstrap attempt has been made to assess errors of the suggested estimation procedure.

Opis:
Modern software systems rely on communication, for example mobile applcations communicating with a central server, distributed systems coordinaing a telecommunications network, or concurrent systems handling events and processes in a desktop application. However, reasoning about concurrent prgrams is hard, since we must reason about each process and the order in which communication might happen between processes. In this paper, I describe a type-driven approach to implementing communicating concurrent programs, using the dependently typed programming language Idris. I show how the type system can be used to describe resource access protocols (such as controlling access to a file handle) and verify that programs correctly follow those prtools. Finally, I show how to use the type system to reason about the order of communication between concurrent processes, ensuring that each end of a communication channel follows a defined protocol.

Jednym z podstawowych mierników płodności kobiet jest cząstkowy współczynnik (drugiej kategorii) płodności ogólnej kobiet rodzących dziecko kolejności p. Szacowanie współczynników płodności możliwe jest na podstawie bieżącej rejestracji ruchu naturalnego ludności. Większym problemem, z uwagi na ruchy wędrówkowe ludności, jest jednak uzyskanie oszacowań dla danych regionalnych oraz dla kohort, które nie były objęte jeszcze rejestracją bieżącą. Estymacja współczynników płodności odbywa się dla wielu szczegółowych przekrojów. Sprawia to. że nawet przy kilkusettysięcznej ogólnopolskiej próbie współczynnik wyznaczany jest dla stosunkowo niewielkiej domeny kobiet urodzonych w danym roku i zamieszkujących w określonym województwie. Rozkład płodności kohorty kobiet w czasie jest rozkładem o silnej prawostronnej asymetrii i o zazwyczaj gładkim przebiegu. W wyniku badania reprezentacyjnego uzyskany rozkład będzie jednak zaburzany na skutek losowego mechanizmu doboru jednostek. Tym samym pojawia się konieczność wygładzenia rozkładu tak, aby zniwelować wpływ składnika losowego w ostatecznym obrazie rozkładu płodności. Celem pracy jest weryfikacja możliwości zastosowania metod wygładzania dla tablic płodności i ocena wpływu wygładzania na efektywność estymacji.

Hyper-heuristics solve hard combinatorial problems by guiding low level heuristics, rather than by manipulating problem solutions directly. Two hyper-heuristics are presented: Five Phase Approach and Genetic Hive. Development paths of the algorithms and testing methods are outlined. Performance of both methods is studied. Useful and interesting experience gained in construction of the hyper-heuristics are presented. Conclusions and recommendations for the future advancement of hyper-heuristic methodologies are discussed.

The paper describes the formulation and implementation of the broadband finite element time domain algorithm. The presented formalism is valid to analysis of electromagnetic phenomena in linear, frequency selective materials. The complex profile of permittivity of materials is approximated using a set of the Lorentz resonance models. The solution of the integro-differential second order equation is obtained using a singlestep integration scheme and a recursive convolution algorithm. The discussed formulation enables to adopt the structure of the narrowband part as well as the phase of calculation of the convolution equations for the subsequent components. The properties of the algorithm are validated using a finite difference broadband algorithm.

Opis:
The recently identified erythrocyte binding antigen-140 (EBA-140) is a member of the Plasmodium falciparum DBL family of erythrocyte binding proteins, which are considered as prospective candidates for malaria vaccine development. The EBA-140 ligand is a paralogue of the well-characterized P. falciparum EBA-175 antigen. They share homology of domain structure, including Region II, which consists of two homologous F1 and F2 domains and is responsible for ligand-erythrocyte interaction during invasion. It was shown that the F2 domain of EBA-175 antigen seems to be more important for erythrocyte binding. In order to study activity and immunogenicity of EBA-140 antigen F2 domain, it is necessary to obtain recombinant protein of high purity and in a sufficient amount, which used to pose a challenge due to the high content of disulphide bridges. Here, we present a new method for expression and purification of Plasmodium falciparum EBA-140 antigen F2 domain in E. coli Rosetta-gami strain in fusion with the maltose binding protein (MBP). The truncated F2 domain formed by spontaneous proteolytic degradation of the fusion protein was purified by affinity chromatography on Ni-NTA resin followed by size exclusion chromatography. Molecular mass of this protein was confirmed by mass spectrometry. Its N-terminal amino acid sequencing revealed a proteolytic cleavage site within the F2 domain. The proper folding of the recombinant, truncated F2 domain of EBA-140 antigen was confirmed by circular dichroism analysis. The truncated F2 domain can specifically bind to human erythrocytes but its binding is not as efficient as that of full Region II. This confirms that both the F1 and F2 domains of EBA-140 antigen are required for effective erythrocyte binding.

Opis:
A new concept concerned with the transformation of acoustic stimuli in the auditory system postulates the existence of a form of spectral analysis applied to the amplitude changes of the stimuli. It is assumed that this analysis takes place in the so-called modulation filters, i.e. bandpass linear filters tuned to different rates of the amplitude changes. The most striking argument supporting this idea is an effect of masking in the amplitude modulation domain whose nature can be easily explained basing on this concept. As the modulation filters are situated on the higher levels of the auditory system, it is also assumed that this form of masking is entirely a central process. However, most of the studies concerned with masking in the modulation domain used monaural listening only. Therefore, the main purpose of the presented here experiments was to investigate whether this type of masking is entirely a central process. Using a Three-Alternative Forced-Choice (3AFC) procedure the binaural and monaural masked thresholds of amplitude modulation were determined. A sinusoidal carrier at a frequency of 4 kHz was amplitude modulated by a specially designed band of noise characterized by a very low value of the crest factor, which was used as a masking signals. Different bandwidths of the modulating masking signals were used as well as different center frequencies to investigate whether the masking patterns in the modulation domain depend on the masker bandwidth and its center frequency. The modulating target (masked) signal was a pure tone at a frequency range from 2 to 256 Hz. Both modulating signals were applied to the same sinusoidal carrier signal. The most effective masking was noticed when the rate of the sinusoidal modulation was close to the center frequency of the masking signal or when it was in its spectral range and decreased outside of this range. The character of this dependence confirms the existence of some form of a frequency selectivity in the modulation rate domain similarly to the audible frequency domain. The thresholds for monaural and binaural listening were very close to each other. This implies that masking in the modulation domain is a central process.

The calcium-activated neutral proteases, μ- and m-calpain, along with their inhibitor, calpastatin, have been demonstrated to mediate a variety of Ca2+-dependent processes including signal transduction, cell proliferation, cell cycle progression, differentiation, apoptosis, membrane fusion, platelet activation and skeletal muscle protein degradation. The cDNA coding for yak calpastatin was amplified and cloned by RT-PCR to investigate and characterize the nucleotide/amino-acid sequence and to predict structure and function of the calpastatin. The present study suggests that the yak calpastatin gene encodes a protein of 786 amino acids that shares 99 % sequence identity with the amino-acid sequence of cattle calpastatin, and that the yak protein is composed of an N-terminal region (domains L and XL) and four repetitive homologous C-terminal domains (d1–d4), in which several prosite motifs are present including short peptide L54–64 (EVKPKEHTEPK in domain L) and GXXE/ DXTIPPXYR (in subdomain B), where X is a variable amino acid. Our results suggest the existence of other functional sites including potential phosphorylation sites for protein kinase C, cAMP- and cGMP-dependent protein kinase, casein kinase II, as well as N-myristoylation and amidation sites that play an important role in molecular regulation of the calpain/calpastatin system. The regulation of the calpain/calpastatin system is determined by the interaction between dIV and dVI in calpains and subdomains A, B, and C in calpastatin.

Opis:
Colorectal cancer, one of the most challenging malignancies, still has a limited number of recognized prognostic and predictive markers indicating appropriate treatment. MACC1 (metastasis-associated in colon cancer-1), a novel regulator of tumor growth and metastasis has recently been identified as an important prognostic factor of metastatic disease in colorectal cancer. The mechanism of MACC1 activity remains undetermined. Here we apply a combination of fold recognition and homology modeling algorithms to draft MACC1 function. The applied methods revealed that the MACC1 protein consists of four domains: ZU5, SH3, and two C-terminal death domains (DD). Previously a similar domain architecture (ZU5-DD) was observed in other proteins, involved mainly in signal transduction and apoptosis regulation. Based on the specific aspects of the closest homologues' biology functional hypotheses on MACC1 are proposed. A broad range of bioinformatic analyzes indicates that MACC1, besides its involvement in signal transduction from the MET receptor, links MET signaling and apoptosis.

Opis:
Envelope constrained filter design is concerned with the time domain synthesis of a filter whose response to a specified input signal stays within prescribed upper and lowe bounds and in addition has minimal noise enhancement. In many practical applications, a "soft" approach, such as least mean square, is not the most suitable and it becomes necessary to use "hard" constraints such as the ones considered in the paper. We present an overview of key ideas related to robust continuous time envelope constrained filter design.

Opis:
Contemporary national security systems face many challenges related to the changes taking place in the security and operating environments. Cognitive warfare, listed as one of such challenges, is often described as “the struggle for hearts and minds” because in cognitive warfare it is the human mind that becomes the battlefield. The aim of the paper is to identify and explore the key assumptions of cognitive warfare. The research process is focused on the following study questions: (1) What are the characteristics of cognitive warfare? (2) How can cognitive operations build an advantage over a competitor? (3) How to build resilience to cognitive operations? The analysis is based on the data collected with the use of the method of narrative literature review. Moreover, the authors’ participatory observations and lessons from national and international military research projects contributed to understanding and discussing the gist of cognitive warfare.

Opis:
Economic processes taking places in the EU markets require systematic changes that will facilitate the international exchange of socio-economic information. All this creates a need for modification of the business statistics information system. System modification is just one element of transformations undertaken by the Central Statistical Office aimed at reforming most of its surveys. These changes focus among other things on exploiting administrative sources for purposes of public statistics. Participation of Poland in the MEETS program offered a unique chance to take steps towards a reform of the present state of business statistics. The results obtained in the MEETS program study was the basis for this article. The objective of the paper was to present the possibility of using administrative registers to short term statistics in the light of DG1 survey.

The main aim of this article is to study the Poisson type problem for anisotropic p-Laplace type equation on long cylindrical domains. The rate of convergence is shown to be exponential, thereby improving earlier known results for similar type of operators. The Poincaré inequality for a pseudo p-Laplace operator on an infinite strip-like domain is also studied and the best constant, like in many other situations in literature for other operators, is shown to be the same with the best Poincaré constant of an analogous problem set on a lower dimension.

Opis:
The ways of the improvement of the method for the determination of steel losses in the electrical devices of basic types are substantiated. The method is refined by taking into account the magnetic system properties at high saturation. The presence of the interrelation between the special features of the domain structure movement and the shape of the hysteresis loop is proved for laminated cores. It enabled the explanation of the causes for the abnormally high values of the losses in the steel and the atypical shapes of the hysteresis loops at its high saturation. The empiric dependence for the determination of steel losses is obtained. It provides for the high convergence of the calculated and experimental data at the actual degree of saturation and can be used in the direct-current operation of the analyzed devices.

In this paper, we investigated plasmonic waveguides in near infrared spectrum, especially at original (λ = 1310 nm) and also communication bands (λ = 1550 nm) using gold nano-elliptic rings. It is possible to shift localized surface plasmon resonance, by appropriate geometrical properties, to the desired wavelength. Three-dimensional simulations utilizing the finite-difference time-domain algorithm are used to determine the set of geometrical parameters of gold nano-elliptic rings for exciting localized surface plasmon resonance at 1310 and 1550 nm. Employing different configurations of gold nano-elliptic rings chains, waveguides are designed, with–3 dB transmission loss coefficients and group velocities calculations for different modes. In comparison with circular nanorings, elliptic rings showed better characteristics, such as high electric field enhancements and low loss transmission coefficients.

Opis:
PDZ domains are ubiquitous protein-protein interaction modules which bind short, usually carboxyterminal fragments of receptors, other integral or membrane-associated proteins, and occasionally cytosolic proteins. Their role in organizing multiprotein complexes at the cellular membrane is crucial for many signaling pathways, but the rules defining their binding specificity are still poorly understood and do not readily explain the observed diversity of their known binding partners. Two homologous RhoA-specific, multidomain nucleotide exchange factors PDZRhoGEF and LARG contain PDZ domains which show a particularly broad recognition profile, as suggested by the identification of five diverse biological targets. To investigate the molecular roots of this phenomenon, we constructed a phage display library of random carboxyterminal hexapeptides. Peptide variants corresponding to the sequences identified in library selection were synthesized and their affinities for both PDZ domains were measured and compared with those of peptides derived from sequences of natural partners. Based on the analysis of the binding sequences identified for PDZRhoGEF, we propose a sequence for an 'optimal' binding partner. Our results support the hypothesis that PDZ-peptide interactions may be best understood when one considers the sum of entropic and dynamic effects for each peptide as a whole entity, rather than preferences for specific residues at a given position.

Opis:
Lymphoid enhancer-binding factor-1 (LEF-1), a member of the high mobility group (HMG) family of proteins, regulates expression of T-cell receptor-α gene and is one of the key regulatory molecules in the epithelial-mesenchymal interactions during embryonic development. Among others, LEF-1 regulates expression of cytokeratin genes involved in formation of hair follicles and the gene encoding the cell-adhesion molecule E-cadherin. Transcription factor LEF-1, which acts as a dimer, binds β-catenin and is involved in signal transduction by the wnt pathway. We have cloned and sequenced a novel isoform of human LEF-1 gene transcript. This isoform encodes a truncated protein devoid of HMG domain and nuclear localization signal but retaining β-catenin binding domain. This isoform might either act in a dominant-negative manner by interfering with native LEF-1, or might bind β-catenin in the cytosol, which would result in attenuation of the signals transmitted by theLEF-b-catenin pathway.

Opis:
Nowadays, with growing use of location-aware, wirelessly connected, mobile devices, we can easily capture trajectories of mobile objects. To exploit these raw trajectories, we need to enhance them with semantic information. Several research fields are currently focusing on semantic trajectories to support inferences and queries to help users validate and discover more knowledge about mobile objects. The inference mechanism is needed for queries on semantic trajectories connected to other sources of information. Time and space knowledge are fundamental sources of information used by the inference operation on semantic trajectories. This article discusses new approach for inference mechanisms on semantic trajectories. The proposed solution is based on an ontological approach for modelling semantic trajectories integrating time concepts and rules. We present a case study with experiments, optimization and evaluation to show the complexity of inference and queries. Then, we introduce a refinement algorithm based on temporal neighbour to enhance temporal inference. The results show the positive impact of our propos al on reducing the complexity of the inference mechanism.

The spectral Chebyshev collocation method and the influence matrix algorithm are applied for solution of the Stokes problem in each subdomain resulting from time discretization of the Navier-Stokes equations, while the patching conditions (continuity of the solution and continuity of its first order derivative) at the interfaces between subdomains are satisfied using the iterative domain decomposition algorithm.

Safety analysis of navigation over a given area may cover application of various risk measures for ship collisions. One of them is percentage of the so called near- miss situations (potential collision situations). In this article a method of automatic detection of such situations based on the data from Automatic Identification System (AIS), is proposed. The method utilizes input parameters such as: collision risk measure based on ship’s domain concept, relative speed between ships as well as their course difference. For classification of ships encounters, there is used a neuro-fuzzy network which estimates a degree of collision hazard on the basis of a set of rules. The worked out method makes it possibile to apply an arbitrary ship’s domain as well as to learn the classifier on the basis of opinions of experts interpreting the data from the AIS.

Druga zaś porusza problem wykorzystania metafory kognitywnej jako podstawowego narzędzia konceptualizacji abstrakcyjnej sfery myślenia. Dodatkowym celem tekstu jest ukazanie obecności metafory w codziennych procesach komunikacji, konceptualizacji potocznego doświadczenia oraz co za tym idzie – praktyce naukowej i edukacyjno-pedagogicznej.
The aim of the paper is to provide a critical analysis of the basic assumptions of the cognitive theory of metaphor. The first part is devoted to the issues related to the coherence of the concept of metaphorical mapping. The second one discusses the validity of the metaphorization process in terms of schema-concretization framework. Finally, the third part raises the problem of using cognitive metaphor as the primary tool for the conceptualization of the realm of abstract thinking. An additional objective of the text is to display the presence of metaphor in everyday communication processes, conceptualization of common experience and thus also in the scientific and educational practice.

Opis:
Based on real-time multi-domain communication signal analysis architecture, a high-efficiency blind carrier frequency estimation algorithm using the power spectrum symmetry of the measured modulated signal is presented. The proposed algorithm, which utilizes the moving averaged power spectrum achieved by the realtime spectrum analysis, iteratively identifies the carrier frequency in according to the power difference between the upper sideband and lower sideband, which is defined and revised by the estimated carrier frequency in each iteration. When the power difference of the two sidebands converges to the preset threshold, the carrier frequency can be obtained. For the modulation analysis, the measured signal can be coarsely compensated by the estimated result, and the residual carrier frequency error is eliminated by a following carrier synchronization loop. Compared with previous works, owing to the moving averaged power spectrum normalization and the smart iterative step variation mechanism for the two sidebands definition, the carrier frequency estimation accuracy and speed can be significantly improved without increasing the computational effort. Experimental results are included to demonstrate the outstanding performance of the proposed algorithm.

The Bugis community in Malaysia has to adapt to a more dominant local language, namely Malay language, for survival. The objective of this study is, (1) to identify the languages used by the community, (2) to analyse the language choice used in the primary domains that have been identified, namely family and employment domains, and (3) to discuss the factors involved in the language choice used in this community. The research methods utilized in this study are fieldworks, questionnaire, semi-structured interviews, and observations. Data collection was carried out in Pontian and Pasir Gudang, Johor as well as in Pandamaran, Selangor. A total of 200 informants who were randomly selected from the Bugis community participated in this study. Data analysis was carried out based on the Fishman’s (1972) domain analysis. The results of the study reveal that most of the bilingual Bugis community prioritize Malay as the main language in their daily communication. This study provides information on the language choice of the bilingual Bugis community in Peninsular Malaysia, which has adapted to the local language. This study might be beneficial to nation building through the mastery and use of Malay language among minority communities in Malaysia.

Opis:
Purpose – This paper aims to present a study on the effect of income and expense shifting on the corporate income tax evasion – an example of intentional noncompliance practiced by tax agents. The authors expected that the tool used would differentiate the extent of understatement of tax liability. Design/methodology/approach – Two experiments were conducted in which young (N 5 62) and experienced (N 5 68) tax agents read a scenario placing them in a position of an employee responsible for tax planning and calculations of tax liabilities. The respondents’ task was to decide about the extent of the tax liability understatement using income or expense shifting. Findings – Research demonstrated significantly higher extent of corporate income tax understatement when using income shifting compared to expense shifting in case of experienced tax agents (Study 2) and on tendency level among young tax agents (Study 1). Research limitations/implications – Results of the studies might be of interest to managers paying attention to tax procedures within the company, governmental agencies investigating corporate tax evasion, as well as educators responsible for tax agents’ initial training and lifelong learning. Originality/value – This study concentrates on tax agents who are employed in companies and corporate income tax evasion, which has not been analyzed in the literature so far.

Opis:
W artykule przedstawiono problematykę pomiarów jakości energii elektrycznej oraz zaprezentowano najważniejsze metody analizy zakłóceń występujących w sieciach elektroenergetycznych, jakie rozwijane są w zespole zajmującym się jakością energii elektrycznej w Instytucie Automatyki i Informatyki Politechniki Opolskiej. Przedstawiono systematykę metod analiz sygnałów oraz określono metody wykorzystywane obecnie w pomiarach sygnałów elektrycznych. Ponadto zaprezentowano metody alternatywne do transformacji Fouriera umożliwiające precyzyjną analizę częstotliwościową (analiza Prony'ego) oraz lokalizację zakłóceń za pomocą metod czasowo-częstotliwościowych (transformacja Falkowa, dyskretna transformacja Falkowa, dystrybucja Wignera-Ville'a i jej odmiany, transformacja Gabora-Wignera).
The issue of measuring power quality parameters and the most important analyses of disturbances occurring in the power network are presented in the paper. These subjects are developed by a power quality and signal analysis group, working at the Faculty of Electrical Engineering, Automatic Control and Informatics. The basic classification of signal analysis methods is given in the paper (Fig. 1). Moreover, the methods currently used in power quality measurement systems are described. In most cases the analyses are based on Fourier Transformation [2-4]. The methods, due to 10-cycles measurement period, cause significant computational errors in case of existence of short duration harmonics in a signal. Moreover, very precise synchronization of the sampling frequency and real power wave-form frequency is needed. Therefore other kinds of analyses in power quality measurement systems are currently investigated. The alternative to Fourier Transformation methods allowing precise estimation of the signal spectrum is Prony analysis [5]. The analysis enables extracting frequency components on the basis of a much shorter measurement window than FFT [6-10]. For localizing the power disturbances, linear (Short-Time Fourier analysis STFT, Gabor Transform GT [12, 13], Wavelet Transform [14, 15, 16]) and bilinear (Wigner-Ville WVD, Pseudo-WVD [17,18]) time-frequency analyses are performed. The combination of both groups of methods (Gabor-Wigner Transform GWT [19,20]) is also presented in the paper. Application of image processing algorithms [21, 22] is also considered in the paper.

Opis:
The use of electromagnetic conductivity and electrical resistivity geophysical techniques has been employed in this study to investigate the occurrence, thickness, and spatial distribution of bitumen deposit around Makun-Omi in the Ijebu Waterside area of southwestern Nigeria. Subsurface apparent conductivity distribution data obtained using Geonic 34-3 equipment along fifteen traverses which sounded from different depths of 7.5, 15, 30 and 60 m at inter-coil separation of 10, 20 and 40 m in vertical and horizontal coupling modes and ground resistivity distribution measurements, obtained using Geopulse Tiger Allied resistivity meter at fourteen Vertical Electrical Sounding (VES) stations, were processed and employed to characterize the subsurface in terms of tar sands distribution. The conductivity and resistivity distribution in the form of a 3D earth model, iso-depth maps, 2D sections generated from the processed conductivity and resistivity data indicate relatively low conductivity <20 mS/m and high resistivity >1300 Ωm values around tar/bitumen impregnated sands which mostly occurred in the southern part of the study area. Clearly defined conductivity and resistivity anomalies which delineate the lateral and vertical occurrence of tar impregnated sands underscore the efficacy of integrating electromagnetic and electrical resistivity geophysical techniques to identify occurrence of economic deposits of tar sands in parts of southwestern Nigeria.

Opis:
Existing ontologies are a valuable source of domain knowledge. That knowledge could be extracted and reused to create domain models. The extraction process can be aided by tools that enable browsing ontology, marking interesting notions and automatic conversion of selected elements to other notations. The paper presents a tool that can be used for SUMO to UML translation. Such transformation is feasible and results in a high-quality domain model, which is consistent, correct, and complete providing that input ontology has the same features.
