Opis:
Distinctively mathematical explanations (DMEs) explain natural phenomena primarily by appeal to mathematical facts. One important question is whether there can be an ontic account of DME. An ontic account of DME would treat the explananda and explanantia of DMEs as ontic items (ontic objects, properties, structures, etc.) and the explanatory relation between them as an ontic relation (e.g., Pincock, 2015; Povich, 2021). Here I present a conventionalist account of DME, defend it against objections, and argue that it should be considered ontic. Notably, if indeed it is ontic, the conventionalist account seems to avoid a convincing objection to other ontic accounts (Kuorikoski, 2021).

Opis:
Current advances in type-II superlattice (T2SL) research at Fraunhofer IAF are elaborated on in this paper. First, the use of metastructures for quantum efficiency (QE) enhancement in the longwave infrared (LWIR) is presented. Finite element modelling results are reported on that suggest a potential for doubling of the QE at certain wavelengths with the investigated device structure. Next, characterisation results of midwave infrared (MIWR) InAs/InAsSb T2SL nBn detectors are shown. The low, diffusion-limited dark current above 120 K and a QE of 60% are comparable to the state-of-the-art. Finally, groundwork for InAs/GaSb T2SL MWIR/LWIR dual-band detector arrays based on a back-to-back heterojunction diode device concept is presented. The dry etching technology allows for steep etch trenches and full pixel reticulation with a fill factor of about 70% at 12 μm pitch. The detector characterisation at 77 K and ±250 mV bias demonstrates the bias-switchable operation mode with dark current densities of 6.1·10ˉ⁹ A/cm² in the MWIR and 5.3·10ˉ⁴ A/cm² in the LWIR.

Opis:
In the Paleozoic, one large ocean once separated the Eurasia of the north and the Gondwana of the south, but it has two names, Paleo-Tethys and Rheic, suggesting different tectonic history. The Paleo-Tethys represent the ocean from east Asia to Middle East regions and vanished in Early Mesozoic, while the Rheic existed across the Europe and finally closed in Carboniferous. The two oceans coevolved for a long time, but the interaction and mutual effect at subduction and collision stages are not well understood. Initiation processes of ocean spreading, subduction and collision are crucial in plate tectonics, so resolving the timing for these turning points may greatly enhanced the precision and accuracy of reconstruction of the two oceans, especially for the western Paleo-Tethys. In NE Iran, we find that all the Paleozoic clastic rocks record two major zircon U-Pb age groups peaked at ~800 Ma and ~600 Ma. Consistency in age patterns show a dominant provenance from Neoproterozoic basement of the north Gondwana and a long-lasting passive margin sedimentation after the spreading of the Paleo-Tethys. This environment was interrupted by initial collision between the Turan (Eurasia) and Central Iran (Gondwana) Blocks with massive coarse clastic deposition, i.e. the protolith of the Mashhad Phyllite, in a peripheral foreland basin on the Paleozoic passive margin. The Mashhad Phyllite yields a striking provenance change from passive margin to active margin. The Paleozoic ages reveal a long-lived subduction zone at the south Turan Block initiated since the latest Ordovician. More importantly, the provenance shift better constrains the initial collision timing with the maximum deposition age of the Mashhad Phyllite (~228 Ma) refining the evolution history of Paleo-Tethys. Based on our new results and previous data, we compare the tectonic history of the Paleo-Tethys in its western segment with eastern Rheic, and further discuss the interaction between the Rheic and Paleo-Tethys. We find existence of a lateral subduction zone plays a crucial rule in initiating new subduction zone after an old oceanic plate vanishes and two continents collides, while a lateral collision can also result into shallowing of subducted slab and preservation of coeval compressional structures. These new insights help us to better interpret the emplacement of high-pressure metamorphic rocks during subduction and subduction zone jump when the Rheic and Paleo-Tethys coevolved.

Opis:
Ga-free InAs/InAsSb type-II superlattice structures grown on GaSb substrates have demonstrated high performance for mid-wave infrared applications. However, realisation of long wavelength infrared photodetectors based on this material system still presents challenges, especially in terms of reduced quantum efficiency. This reduction is due, in part, to the increased type-II superlattice period required to attain longer wavelengths, as thicker periods decrease the wave-function overlap for the spatially separated quantum wells. One way to improve long wavelength infrared performance is to modify the type-II superlattice designs with a shorter superlattice period for a given wavelength, thereby increasing the wave-function overlap and the resulting optical absorption. Long wavelength infrared epitaxial structures with reduced periods have been realised by shifting the lattice constant of the type-II superlattice from GaSb to AlSb. Alternatively, epitaxial growth on substrates with orientations different than the traditional (100) surface presents another way for superlattice period reduction. In this work, the authors evaluate the performance of long wavelength infrared type-II superlattice detectors grown by molecular beam epitaxy using two different approaches to reduce the superlattice period: first, a metamorphic buffer to target the AlSb lattice parameter, and second, structures lattices matched to GaSb using substrates with different orientations. The use of the metamorphic buffer enabled a ~30% reduction in the superlattice period compared to reference baseline structures, maintaining a high quantum efficiency, but with the elevated dark current related to defects generated in the metamorphic buffer. Red-shift in a cut-off wavelength obtained from growths on highindex substrates offers a potential path to improve the infrared photodetector characteristics. Focal plane arrays were fabricated on (100), (311)A- and (211)B-oriented structures to compare the performance of each approach.

Opis:
This paper considers three recent studies on the negative theology of the Neoplatonists and Dionysius the Areopagite. The first is that of Lloyd Gerson, who argues that the One in Plotinus does not lack transcend existence but only definite existence; the second is the contrary thesis of Eric D. Perl that not only the One of Plotinus but the God of Dionysius transcend all being in such a way that they cannot be credited with existence. After some criticism of both the paper turns to the argument of Timothy D. Knepper that even the ineffability of the divine cannot be stated on our present plane of knowledge; it concludes with some reflections on the appeal to present or future experience as alternatives to epistemology as this is commonly understood in the analytical tradition of philosophy.

In this paper I will give some provisional answers to the questions how one can be a Christian philosopher rather than just a philosopher who happens to be a Christian, how one can be a Reformation philosopher rather than just a Christian philosopher whohappens to be a Reformation Christian, and how one can be a Baptist philosopher rather than just a Reformation philosopher who happens to be a Baptist. A good way to be a philosopher is to, like Socrates, seek wisdom concerning spiritual good. A good wayto be a specifically Christian philosopher is to, like Augustine, seek that wisdom in Jesus Christ. A good way to be a specifically Reformation philosopher is to recognize and reflect on a distinction between two inseparable spiritual goods on which we are seeking wisdom: justification and sanctification. A good way to be a specifically Baptist philosopher, taking some inspiration from the likes of Locke and Kierkegaard, is to also recognize and reflect on some signs of these spiritual goods which Baptists emphasize: resistance to the idea of a state church and believer’s baptism.

Opis:
The highly infectious African swine fever virus (ASFV) is currently the only known DNA arbovirus within the Asfarviridae family which primarily infects domestic pigs and wild boars. African swine fever (ASF) leads to a mortality rate of up to 100% which has caused massive socio-economic losses worldwide. Previous research indicates that ASFV’s virulence can be attributed to polyprotein pp62, which plays a crucial role in viral assembly and core maturation. This particular study utilized in silico analysis to identify highly conserved cytotoxic T-cell epitopes in pp62 that can potentially serve as key components for future ASFV vaccines. To achieve this, the researchers retrieved, clustered, and aligned the peptide sequences of pp62. Subsequently, the aligned sequences were analyzed to identify epitopes that bind promiscuously to the swine major histocompatibility complex I (MHC I) alleles and exhibiting MHC IC50 values < 500 nM. Additionally, peptide sequences with positive proteasome and TAP scores were considered. Potential cross-reactivity was assessed by comparing the peptide sequences against available proteome sequences of Sus scrofa domesticus in various databases. Furthermore, molecular docking was conducted to evaluate the binding of candidate epitopes with swine leukocyte antigen-1*0401 (SLA-1*0401). The dissociation constants, binding energies, root mean square deviation, and root mean square fluctuation values for the SLA-epitope complexes were compared with a positive reference. In the course of the study, 21 highly conserved CD8+ epitopes were identified, out of which four were further assessed for their potential immunogenicity. The results demonstrated that the highly conserved CD8+ epitopes discovered in this study are promising for integration into future ASFV vaccine formulations. As preliminary data, it is anticipated that these findings will subsequently undergo in vitro and in vivo studies in the future.

But for the majority of the data, we are unable to identify these ingredients with high certainty. In this paper, we discuss a selection of plant and mineral names both from a humanities and sciences point of view. In one case, the scientists were even able to examine a plant in situ. The conclusion of our paper is that a close collaboration between sciences and humanities is essential to avoid mistakes in the identification of materia medica.

Opis:
Since the first edition of this reference was published 25 years ago much has taken place in the polygraph field, progress which has continued in the decade since the last edition of the Terminology Reference. The transition from analog to digital polygraph is now complete, the polygraph profession has accomplished the shift from authority-based practices to those that are evidence-based, concepts and terms adopted by the polygraph field are substantially more mainstream, new credibility assessment technologies have appeared while others have disappeared, and much to the surprise of critics and detractors, predictions of the demise of the polygraph have proven to be premature. In this fourth edition of the Terminology Reference for the Science of Psychophysiological Detection of Deception we strived to capture these changes. We have updated the references, added new terms, removed others, and included images for some terms to help readers understand them better. We hope readers appreciate these updates. And finally, we sadly report the passing of our friend, colleague and contributor to previous editions of this work, Shirley Sturm in 2020. Shirley was one of the greats in the polygraph field. She was the first woman President of the American Polygraph Association, a teacher, a coveted mentor, and a fiercely independent thinker. We and the rest of the polygraph field will miss Shirley, her sense of humor, her passion for polygraph, her concern for her fellow practitioners, her commitment to the field. There was always only one Shirley Sturm and we were fortunate to have known her. Because of her lasting contribution to our shared field of endeavor we dedicate this edition of the Terminology Reference to Shirley Sturm.

Opis:
INTRODUCTION: Gaming disorder is defined as a pattern of gaming behaviour characterised by impaired control over gaming, prioritisation of gaming over other activities to the point where gaming takes precedence over other interests and daily activities, and persistence or escalation of gaming despite negative consequences. Given the increasing global interest in videogames, particularly among adolescents and young adults, this study investigated the prevalence of gaming disorder and its associated factors among Sri Lankan adolescents and young adults, with a focus on factors associated with gaming addiction. MATERIALS AND METHODS: A cross-sectional survey was conducted involving 401 Sri Lankan adolescents and young adults who played video games, through an anonymous online survey using snowball sampling. The survey comprised four sections: demographic data, influencing factors for game playing, the seven-item Game Addiction Scale and a validated depression scale (nine-item Patient Health Questionnaire). SPSS IBM (version 27) was used for data analysis, which includes means, standard deviations, frequencies, percentages, Pearson’s correlation and chi-square tests. RESULTS: A total of 401 gamers participated, comprising adolescents (10-18 years; 9.5%) and young adults (19-35 years; 90.5%). The majority were non-gaming addicts (71.57%), and among the gaming addicts, 8.48% were classified as monothetic gaming addicts, while 19.5% were classified polythetic gaming addicts. Slightly more males were game addicts (52.63%) than females. There was a low positive correlation between videogame addiction and depression (r=0.321). More than half of the sample believed that visual triggers (58.6%) and frequent reward systems (56.1%) influenced their gameplay. There was a significant association (p <0.05) between gaming addiction and the three observed characteristics: visual triggers, audio triggers, and frequent rewards. CONCLUSIONS: Just under one-tenth of the study population sampled was classified as having a gaming addiction, with males having a slightly higher prevalence than females. The positive correlation between gaming disorder and depression suggests a consequential and potentially life-threatening outcome, wherein depression emerges as a serious consequence of addiction to gaming. When the structural characteristics of videogames, such as auditory, visual and frequent reward systems were considered, game addicts were more influenced by them.

Purpose The aim of this study was to determine frequency and distribution of sports- and recreation-related injuries (SRIs) affecting children and adolescents who visited a northern tier regional medical center emergency department during a 15-year period. Material and methods A descriptive epidemiologic design was employed to retrospectively examine age, gender, month and year of injury, location of injury, sport/recreational activity, mechanism of injury, type and severity of injury, hospital admission and length of stay. Frequency of reported injuries were compared in categories of single factors using Chi-square tests of homogeneity. The impact of risk factors – gender, age class, and sport/activity – on incidence ratios were analyzed via Poisson regression. All statistical analyses were run in R. Results Findings heretofore unreported or inconsistent with previous emergency department (ED) studies include a peak injury occurrence of SRIs during September; a preponderance of head/neck injuries and fractures and a higher percent of admitted patients; frequent occurrence of ice hockey injuries; increased severity of injury during ages 10-14; and a trend during 2000-2014 showing increased injury rate of various types of recreational injuries. Findings consistent with previous ED studies included variable distribution of injuries by age, gender and sport/activity; increased frequency of SRIs during ages 12-15 years and during the warmer months of the year; and trends of increased frequency of SRIs affecting females, increased injury rate of closed head injuries, and decreased occurrence of bicycle injuries during the study period. Further to these findings, several suggestions are made to inform and guide local injury prevention efforts and further research. Conclusions Our study results provide information on a region-specific occurrence and distribution of SRIs in a northern tier hospital catchment area that can be valuable to guide regional injury prevention efforts and further research to evaluate specific patterns identified and success of prevention efforts.

Opis:
Background. Sports can function in a number of contexts in society, therefore government-related financial contribution can be justified. The resource allocation decisions of the contributor are always a relevant topic. The aim of this paper was to create a modified portfolio matrix tool for resource allocation purposes, which can be used at the national, regional, municipal or organizational level. Material and methods. The study consists of two researches conducted with the use of Google Forms. Two target groups (sports clubs from Baranya County and outstanding sports clubs in Hungary) were taken into consideration. Results. During the interviews in each group of sports clubs, 40 and 52 sports respectively were evaluated. The 12 most important sports were selected for this study. It can be seen that there is no significant difference between the regional and national rankings of sports. Outstanding sports clubs evaluated the given sports higher overall than regional sports clubs with regard to both categories: “the future vision of sport” and “the current impact”. Conclusions. The sport portfolio matrix can serve as the basis for the resource allocation decisions, but it has to be complemented with other funding schemes as this tool incentivizes mostly present performance, whereas strategic considerations should have another platform.
Wprowadzenie. Sport może funkcjonować w wielu kontekstach w społeczeństwie, dlatego wkład finansowy pochodzący od organów rządowych może mieć swoje uzasadnienie. Decyzje dotyczące alokacji zasobów przez podmiot wnoszący wkład są zawsze istotną kwestią. Celem niniejszej pracy było stworzenie zmodyfikowanego narzędzia macierzy portfelowej w celu alokacji środków, które może być stosowane na poziomie krajowym, regionalnym, miejskim lub organizacyjnym. Materiał i metody. Niniejsza praca składa się z dwóch badań, przeprowadzonych z wykorzystaniem Google Forms. Uwzględniono dwie grupy docelowe (kluby sportowe komitatu Baranyi oraz wyróżniające się kluby sportowe na Węgrzech). Wyniki. W wywiadach w poszczególnych grupach klubów sportowych, oceniono odpowiednio 40 i 52 dyscypliny sportowe. Do celów niniejszej pracy wybrano 12 najważniejszych. Można zauważyć, żenie ma znaczącej różnicy pomiędzy rankingiem sportów na poziomie regionalnym i krajowym. Kluby sportowe o wybitnych osiągnięciach oceniły dane dyscypliny sportowe ogólnie wyżej niż regionalne kluby sportowe w obu kategoriach: „wizja przyszłości sportu” oraz „bieżący wpływ”. Wnioski. Macierz portfelowa w sporcie może służyć jako podstawa do podejmowania decyzji o alokacji środków, ale musi być uzupełniona o inne systemy finansowania, ponieważ narzędzie to opiera się głównie na obecnych wynikach, podczas gdy względy strategiczne powinny wykorzystywać inną platformę.
