Opis:
A pair potential for lead (Pb) is extracted from the ab-initio energy-volume data using the lattice inversion procedure of Carlsson and co-workers [Phil. Mag. 41 (1980), p. 241]. Because of a limited accuracy of the ab-initio techniques, we extrapolate the energy-volume data for low-density systems with suitable analytical tail functions. We discuss the dependence of the molecular dynamics (MD) simulation structural results and the elastic modules on the choice of the cohesive energy tail function. The MD-simulated radial distribution functions (RDFs), obtained for several energy tails, in several temperatures are discussed.

Opis:
The travel time tomography technology had achieved wide application, the hinge of tomography was inversion algorithm, the ray path tracing technology had a great impact on the inversion results. In order to improve the SNR of inversion image, comprehensive utilization of inversion results with different ray tracing can be used. We presented an imaging fusion method based on improved Wilkinson iteration method. Firstly, the shortest path method and the linear travel time interpolation were used for forward calculation; then combined the improved Wilkinson iteration method with super relaxation precondition method to reduce the condition number of matrix and accelerate iterative speed, the precise integration method was used to solve the inverse matrix more precisely in tomography inversion process; finally, use wavelet transform for image fusion, obtain the final image. Therefore, the ill- conditioned linear equations were changed into iterative normal system through two times of treatment and using images with different forward algorithms for image fusion, it reduced the influence effect of measurement error on imaging. Simulation results showed that, this method can eliminate the artifacts in images effectively, it had extensive practical significance.

Opis:
Joint inversion is a widely used geophysical method that allows model parameters to be obtained from the observed data. Pareto inversion results are a set of solutions that include the Pareto front, which consists of non-dominated solutions. All solutions from the Pareto front are considered the most feasible models from which a particular one can be chosen as the final solution. In this paper, it is shown that models represented by points on the Pareto front do not reflect the shape of the real model. In this contribution, a collective approach is proposed to interpret the geometry of models retrieved in inversion. Instead of choosing single solutions from the Pareto front, all obtained solutions were combined in one “heat map”, which is a plot representing the frequency of points belonging to all returned objects from the solution set. The conducted experiment showed that this approach limits the problem of equivalence and is a promising way of representing the geometry of the model that was retrieved in the inversion process.

Opis:
The paper deals with the conformal mapping of finite, plane, simply connected domains, representing oceans, lakes, estuaries, bays, lagoons, and other natural water bodies of this kind. As a rule, they are bounded by geometrically complex shorelines. The partial differential problems investigated in Oceanology and posed in such domains have turned out to be difficult to solve for at least three reasons. They follow on from the mathematical properties of the differential equations governing such problems, from the just-mentioned geometrical complexity of the domains of solution, and from the sensitivity of the solutions to boundary conditions. In view of the last reason the contours admitted as boundaries of the domains of the solution ought to be as close to the real shorelines as possible. The obviously inaccurate approximation of the shorelines by ‘staircases’, which appears rather often (cf. Catewicz & Jankowski 1983, Lin & Chandler-Wilde 1996) as a consequence of applying finite difference methods to the solution of the partial differential problems, raises serious doubts from the point of view of Numerical Fluid Mechanics. It is recalled in the paper that such inaccuracies are not unavoidable: that complicated plane domains can be transformed accurately by means of properly applied conformal mapping onto regular, canonical domains – in particular, onto discs or squares. Such a transformation is demonstrated on the rather difficult example of the Vistula Lagoon. The transformation begins with the decomposition of the domain into five plane subdomains, each one of which is eventually transformed onto a disc. Every such result is arrived at quite independently of the remaining subdomains, by means of a set of properly selected consecutive mappings. Hence, the final canonical domain consists in this case of a system of five discs which, however, within the framework of this differential problem, have to be treated as interconnected. The interconnections involve images of four segments of straight lines, separating the original subdomains. The transformations and the resulting canonical domain presented in the paper are intended to be applied to the solution of certain hydrodynamical problems concerning the Vistula Lagoon, which will be published elsewhere.

Opis:
This article regards Norwid’s Tajemnica Lorda Singelworth in the context of his anthropology as well as historical and cultural background. The author’s notion of “cleanliness,” inspired in some measure by the Gospels, is connected to the circumstances of both Norwid himself and the main character of his puzzling novella. This reading revolves around the image of a balloon flight during which the Lord – as it is argued, following hints already present in studies of Norwid – discards a piece of paper with “physiological content.” This scene is placed in the context of other literary balloon flights and the eccentricity of Baudelaire’s friend Philoxène Boyer. Finally, the article discusses Norwid’s law of inversion, which can be applied in the case of Singelworth.

Opis:
The present study explores the acceptability of postverbal subjects by intermediate and advanced L2 English learners with L1 Macedonian, a pro-drop Slavic language with rich verbal morphology. The two languages differ regarding the distribution of subject-verb inversion (SVI): in Macedonian, it is a default pattern in thetic sentences, but English severely restricts SVI to specific contexts. To test the hypothesis that Macedonian learners encounter difficulties in acquisition of English SVI because of crosslinguistic influence, a grammaticality judgement and correction task was administered to two groups of Macedonian learners of English and a control group of English native speakers. The results revealed that L2 learners find English VS sentences and VS + it-insertion examples more acceptable than the native speakers, but the performance of the advanced group is closer to the native speakers than to the intermediate learners. Both non-native groups accept more readily inappropriate English sentences that conform to typical L1 structures.

Opis:
The paper concerns the effect of thermal inversions on PM10 concentrations in winter seasons between 2004–2005 and 2012–2013 in Tricity. Temperature inversions were analyzed using aerological measurements timed at 00 UTC and 12 UTC obtained from the aerological station in Łeba. The PM10 concentrations were obtained from five Agency of Regional Air Quality stations in the Gdańsk metropolitan area (ARMAAG). The effect of inversion conditions on the variability of daily PM10 concentrations was assessed using single and multiple linear regressions. The unfavorable conditions of PM10 dispersion in the lower troposphere were mostly determined by elevated inversions, which occurred with comparable frequency, nearly 90%, during the day as well as at night. Surface inversions were recorded at a frequency of 30% at night and only 10% during day-time. The strongest adverse effect on PM10 concentrations and their variability during the period of calendar winter was found to be related to the thickness of surface inversions at night. A significant yet substantially less adverse effect during both day and night, however, was found to be related to the thickness of the lowest layer of upper inversion. The high location of the base of upper inversion, primarily during the day-time, contributed to a decrease in PM10 concentration.

Opis:
This research scrutinizes the observation that when the thematic subject is extracted (i.e. questioned) in Jordanian Arabic, temporal/locative inversion may occur. Temporal inversion occurs irrespective of the verb being transitive or intransitive, whereas locative inversion is limited to contexts with an unaccusative verb. This research argues that this distinction correlates with the base-generation of temporal/locative adjuncts; temporal adjuncts are base-generated adjoining to TP, whereas locatives are base-generated adjoining to VP. Temporal but not locative adjuncts resist fronting with vP, demand the use of a tense copula (or a tensed verb), and are not subject to deletion along with the lexical verb. With the assumption that Spec, SubjP must be filled with a non-silent copy due to the effects of the so-called Subject Criterion (Rizzi and Shlonsky 2007), a temporal or locative adjunct, if any, fills this position instead of the extracted thematic subject. Given its low position, a locative adjunct is accessible to Subj0 only when there is no v*P, hence the account of the correlation between locative inversion and the type of the verb. Furthermore, this research explores the existence of temporal/locative inversion in other two Arabic dialects (Najdi Arabic and Iraqi Arabic), arguing for a micro-parametric view of this strategy across Arabic dialects.

Opis:
A number of cities in Poland have been coping with the problem of air pollution levels exceeding the allowable limits, with PM10 airborne particulate considered one of the most hazardous factors for human health. Poland ranks high among European countries with some of the highest levels of airborne particulate pollution, and the Polish cities regularly place high in the EU ranking of those with the highest PM levels (and benzo(a)pyrene, a toxic airborne polycyclic aromatic hydrocarbons, or PAHs). Airborne PM10 concentration levels greatly depend on the prevailing atmospheric and topographic conditions. Temperature inversion represents one of the unfavorable weather conditions and this article attempts to study the effect of thermal conditions prevailing in the Żywiec Basin on airborne PM10 particulate concentrations in immissions. The 2016–2021 winter (heating) seasons were analyzed for pollution emissions, especially those related to heating by the municipal sector and classified as “low emissions”, i.e. emissions from sources not higher than 40 meters. An analysis of the 2016–2021 heating seasons showed the air temperature exerted a significant effect on combustion processes (low emissions) within the Żywiec Basin. The difference between airborne PM10 particulate levels in immissions at temperatures both above and below zero ranged from 86 μg/m3 in the 2016–2017 heating season to 25 μg/m3 in the same period in 2020–2021. Average airborne PM10 particulate concentrations throughout the entire period analyzed stood at 41.3 μg/m3 for the typical temperature distribution in the elevation profile, whereas inversion almost doubled it (72.2 μg/m3).

Opis:
The Upper Cretaceous sequence in the area located between Uniejów, Kłodawa and Ozorków, Central Poland, is dominated by carbonate and carbonate-siliceous deposits. They are represented by limestones, marly limestones, marls and opokas with local gaize intercalations in the uppermost part of the sequence. There is also a complex of Santonian-Campanian clastics immediately adjoining the present-day Mid-Polish Swell near the Kłodawa Salt Diapir. The clastics may represent gravity flow deposits associated with a strong uplift of the Izbica -Kłodawa-Łęczyca Zone due to salt movements during inversion of this structure related to the incipient phase of the Late Cretaceous inversion of the whole Mid-Polish Swell. These processes caused increasing morphological gradients when passing south-westwards to the neighbouring subsiding trough. Detailed sedimentological studies of the clastic series cannot be made due to insufficient material and poor core condition. Investigations of the regional facies distribution and sedimentation, performed both along the areas adjoining the present-day Mid-Polish Swell and in local inversion structures, may help in the elucidation of timing of the incipient tectonic inversion phase of the Mid-Polish Trough which was ultimately transformed into the Mid-Polish Swell during the Early Tertiary.

Opis:
An iterative inversion algorithm for a class of square matrices is derived and tested. The inverted matrix can be defined over both real and complex fields. This algorithm is based only on the operations of addition and multiplication. The numerics of the algorithm can cope with a short number representation and therefore can be very useful in the case of processors with limited possibilities, like different neuro-computers and accelerator cards. The quality of inversion can be traced and tested. The algorithm can be used in the case of singular matrices, and then it automatically produces a result that contains the inverse of this part of the processed matrix which can be inverted. An example of the inversion of a six-order square matrix is presented and discussed.

Opis:
The western frame-margin of the Upper Silesian Coal Basin provides good case studies for structural evolution of the fold-and-thrust belt. This study is concerned with tectonic junctions taking place on the Late Variscan front of the Moravosilesian Fold Zone and coal basin. Clues of evolution of fold-and-thrust belt were reconstructed on the base of six cross-sections and using balancing procedure to calculate the shortening. These structural cross-sections illustrated the two principal positive and negative inversion processes of Upper Silesian Coal Basin. The fold shortening varies in range of 25 up to 30% and in low range of 4 up to 18%. The thrust shortening is contrary to fold shortening and changed range of about 10% up to 50%. In the central part of fold-and-thrust belt summarised shortening is 55%, which gradually decreases northward up to 35% and southward up to 30%.
