description: Satisfiability-based automated reasoning is an approach that is being successfully used in software engineering to validate complex software, including for safety-critical systems. Such reasoning underlies many validation activities, from requirements analysis to design consistency to test coverage. While generally effective, the back-end constraint solvers are often complex and inevitably error-prone, which threatens the soundness of their application. Thus, such solvers need to be validated, which includes checking correctness and explaining (un)satisfiability results returned by them. In this work, we consider satisfiability analysis based on First-Order Logic with relational objects (FOL*) which has been shown to be effective for reasoning about time- and data-sensitive early system designs. We tackle the challenge of validating the correctness of FOL* unsatisfiability results and deriving diagnoses to explain the causes of the unsatisfiability. Inspired by the concept of proofs of UNSAT from SAT/SMT solvers, we define a proof format and proof rules to track the solvers' reasoning steps as sequences of derivations towards UNSAT. We also propose an algorithm to verify the correctness of FOL* proofs while filtering unnecessary derivations and develop a proof-based diagnosis to explain the cause of unsatisfiability. We implemented the proposed proof support on top of the state-of-the-art FOL* satisfiability checker to generate proofs of UNSAT and validated our approach by applying the proof-based diagnoses to explain the causes of well-formedness issues of normative requirements of software systems.

description: В работе представлено влияние различных типов растворителей на спектральные и проводящие свойства тонких пленок фуллерена и пленок [6,6]-метиловый эфир фенил-C61-масляной кислоты (PCBM). Наглядно показано существенное влияние природы растворителя на морфологию поверхности углеродных пленок. Анализ спектров поглощения оптического диапазона показал наличие максимумов в интервале 330 500 нм. Вольт-амперные характеристики показали увеличение кинетики заряда пленок фуллерена, осажденных посредством дихлорметана и тетрахлорметана, при облучении электромагнитным излучением видимого диапазона. Увеличение кинетики заряда при облучении пленок PCBM наблюдается для модификаций, полученных с использованием толуола и дихлорметана.

This is implemented by embedding the one-parameter family of spacetimes in anti-de Sitter space, and as a result we obtain metrically correct Penrose diagrams. For $e \rightarrow m$ two distinct limits are studied.

description: The late-time cosmological dynamics of disformal gravity are investigated using dynamical systems methods. It is shown that in the general case there are no stable attractors that screen fifth-forces locally and simultaneously describe a dark energy dominated universe. Viable scenarios have late-time properties that are independent of the disformal parameters and are identical to the equivalent conformal quintessence model. Our analysis reveals that configurations where the Jordan frame metric becomes singular are only reached in the infinite future, thus explaining the natural pathology resistance observed numerically by several previous works. The viability of models where this can happen is discussed in terms of both the cosmological dynamics and local phenomena. We identify a special parameter tuning such that there is a new fixed point that can match the presently observed dark energy density and equation of state. This model is unviable when the scalar couples to the visible sector but may provide a good candidate model for theories where only dark matter is disformally coupled.

Проецируя полученный результат на биологические системы организма человека, можно сделать вывод о том, что явление изменения площади вихревого тока, возникающего в предутренние часы в период магнитных бурь, приводит к закупорке кровеносного сосуда и к ишемическим явлениям

description: Decades of in-situ solar wind measurements have clearly established the variation of solar wind physical parameters. These variable parameters have been used to classify the solar wind magnetized plasma into different types leading to several classification schemes being developed. These classification schemes, while useful for understanding the solar wind originating processes at the Sun and early detection of space weather events, have left open questions regarding which physical parameters are most useful for classification and how recent advances in our understanding of solar wind transients impact classification. In this work, we use neural networks trained with different solar wind magnetic and plasma characteristics to automatically classify the solar wind in coronal hole, streamer belt, sector reversal and solar transients such as coronal mass ejections comprised of both magnetic obstacles and sheaths. Furthermore, our work demonstrates how probabilistic neural networks can enhance the classification by including a measure of prediction uncertainty. Our work also provides a ranking of the parameters that lead to an improved classification scheme with ~96% accuracy. Our new scheme paves the way for incorporating uncertainty estimates into space weather forecasting with the potential to be implemented on real-time solar wind data.

description: Seit einiger Zeit kommt es zu einem Anstieg von erwerbstätigen Personen gekommen, welche vom Home-Office aus, arbeiten. Die Covid-19 Pandemie, und ihre Strategien zur Eindämmung der Pandemie 2020, haben diese Entwicklung massiv verstärkt und für einen Umschwung des generellen Arbeitsortes gesorgt. Im Zuge dessen wurde auch der Kund*innenkontakt in vielen Fällen von persönlich oder Mix-Formen auf ausschließlich oder hauptsächlich virtuell umgestellt (Videogespräche, Telefonate, E-Mail). Dies stellt Kund*innenbetreuer*innen vor Veränderungen und neue Herausforderungen im CRM. Um ebenjene handelt die empirische Studie der Masterarbeit. Es werden Neugestaltungen und neue Dynamiken beim Management der Kund*innenbeziehung aufgedeckt und beschrieben. Es zeigt sich, dass oftmals neue Kund*innenbeziehungsdynamiken entstehen und teilweise auch eine stärkere Vertrauensbeziehung mit Kund*innen wahrgenommen wird.
description: Over the past few years, there has been an increase in the number of people working from home, in “Home-Office”. The Covid-19 pandemic, and its 2020 containment strategies, have massively reinforced this trend and caused a shift in the general location of work. As a result, customer contact has also shifted in many cases from in-person or mixed forms to exclusively or primarily virtual contact (video calls, phone calls, e-mail). This poses changes and new challenges for customer service representatives in CRM, which is what the empirical study of the master's thesis is about. Innovations and new dynamics in the customer relationship are uncovered and described. It is shown that new customer relationship dynamics emerge and, partly, Interviews show that a stronger relationship of trust with customers is perceived by representatives.

description: Cosmic voids are effective cosmological probes to discriminate among competing world models. Their identification is generally based on density or geometry criteria that, because of their very nature, are prone to shot noise. We propose two void finders that are based on dynamical criterion to select voids in Lagrangian coordinates and minimise the impact of sparse sampling. The first approach exploits the Zel'dovich approximation to trace back in time the orbits of galaxies located in voids and their surroundings, the second uses the observed galaxy-galaxy correlation function to relax the objects' spatial distribution to homogeneity and isotropy. In both cases voids are defined as regions of the negative velocity divergence, that can be regarded as sinks of the back-in-time streamlines of the mass tracers. To assess the performance of our methods we used a dark matter halo mock catalogue CoDECS, and compared the results with those obtained with the ZOBOV void finder. We find that the void divergence profiles are less scattered than the density ones and, therefore, their stacking constitutes a more accurate cosmological probe. The significance of the divergence signal in the central part of voids obtained from both our finders is 60% higher than for overdensity profiles in the ZOBOV case. The ellipticity of the stacked void measured in the divergence field is closer to unity, as expected, than what is found when using halo positions. Therefore our void finders are complementary to the existing methods, that should contribute to improve the accuracy of void-based cosmological tests.

description: We study actions of countable discrete groups which are amenable in the sense that there exists a mean on X which is invariant under the action of G. Assuming that G is nonamenable, we obtain structural results for the stabilizer subgroups of amenable actions which allow us to relate the first l2-Betti number of G with that of the stabilizer subgroups. An analogous relationship is also shown to hold for cost. This relationship becomes even more pronounced for transitive amenable actions, leading to a simple criterion for vanishing of the first l2-Betti number and triviality of cost. Moreover, for any marked finitely generated nonamenable group G we establish a uniform isoperimetric threshold for Schreier graphs G/H of G, beyond which the group H is necessarily weakly normal in G. Even more can be said in the particular case of an atomless mean for the conjugation action -- that is, when G is inner amenable. We show that inner amenable groups have cost 1 and moreover they have fixed price. We establish U_{fin}-cocycle superrigidity for the Bernoulli shift of any nonamenable inner amenable group. In addition, we provide a concrete structure theorem for inner amenable linear groups over an arbitrary field. We also completely characterize linear groups which are stable in the sense of Jones and Schmidt. Our analysis of stability leads to many new examples of stable groups; notably, all nontrivial countable subgroups of the group H(R), recently studied by Monod, are stable. This includes nonamenable groups constructed by Monod and by Lodha and Moore, as well as Thompson's group F.
description: Theorem 11 (the cocycle superrigidity statement) has been optimized. The statement is now stronger and simpler, and the proof (in section 5) is shorter. This makes Appendix C obsolete, so it has been removed. The other change is that Remark 7.5 from the old version has been moved to the introduction and is now Theorem 15

Цель работы – анализ методики исследования переходных процессов в ОПЗ n-p перехода кремниевых n+-p-p+ структур, облученных низкоэнергетическими протонами. Задача – определение эффективного времени жизни  носителей заряда в области пространственного заряда (ОПЗ) n+-p перехода. Исследовались n+-p-p+структуры из кремния, выращенного методом Чохральского, облучённые со стороны n+-слоя потоком низкоэнергетических протонов при температуре образцов 300 K и 83 K. Для измерения импульсных характеристик использовались биполярные прямоугольные импульсы напряжения с постоянной амплитудой 10 mV и частотой 200 kHz. Экспериментальные данные объясняются с помощью моделей нестационарного переноса носителей заряда в неоднородных полупроводниках и образования радиационных дефектов в кремнии под действием протонов.

description: In a unified picture both inflation and present dynamical dark energy arise from the same scalar field. The history of the Universe describes a crossover from a scale invariant "past fixed point" where all particles are massless, to a "future fixed point" for which spontaneous breaking of the exact scale symmetry generates the particle masses. The cosmological solution can be extrapolated to the infinite past in physical time - the universe has no beginning. This is seen most easily in a frame where particle masses and the Planck mass are field-dependent and increase with time. In this "freeze frame" the Universe shrinks and heats up during radiation and matter domination. In the equivalent, but singular Einstein frame cosmic history finds the familiar big bang description. The vicinity of the past fixed point corresponds to inflation. It ends at a first stage of the crossover. A simple model with no more free parameters than $Λ$CDM predicts for the primordial fluctuations a relation between the tensor amplitude $r$ and the spectral index $n,r=8.19(1-n)-0.137$. The crossover is completed by a second stage where the beyond-standard-model sector undergoes the transition to the future fixed point. The resulting increase of neutrino masses stops a cosmological scaling solution, relating the present dark energy density to the present neutrino mass. At present our simple model seems compatible with all observational tests. We discuss how the fixed points can be rooted within quantum gravity in a crossover between ultraviolet and infrared fixed points. Then quantum properties of gravity could be tested both by very early and late cosmology.

description: Das Ziel dieser Masterarbeit ist es, die Subjektiven Theorien von Lehrpersonen zum Umgang mit Komplexität und Kontroversität im Themenfeld ‚Ernährung und Klimaschutz‘ zu erforschen. Im theoretischen Teil dieser Arbeit werden relevanten Begrifflichkeiten und die Verankerung des Themenfeldes in den Lehrplänen der Sekundarstufe behandelt. Im empirischen Teil dieser Arbeit werden Untersuchungen, basierend auf dem Forschungs-programm Subjektiven Theorien nach Groeben, Wahl, Schlee und Scheele (1988), durch-geführt. Dazu wurden drei (angehende) Lehrpersonen im Zuge der kommunikativen Validierung des Forschungsprogramms mittels halboffenen Leitfadeninterviews befragt. Diese Interviews werden audiographisch aufgezeichnet, transkribiert und ausgewertet. Der zweite Schritt der kommunikativen Validierung ist die Rekonstruktion der Subjektiven Theorien. Dabei werden den Befragten Begrifflichkeiten aus ihrem ersten Interview ge-zeigt. Diese Begrifflichkeiten werden aus dem jeweiligen Erstinterview mittels qualitativer Inhaltsanalyse nach Mayring (2015) extrahiert. Die Befragten sollen diese Begrifflich-keiten beim zweiten Interviewtermin in eine Concept-Map bringen. Auch diese Interviews werden audiographisch aufgezeichnet und die Concept-Maps werden digital gesichert. Auch das zweite Interview jeder befragten Person wird nach Mayring (2015) ausgewertet. Die Ergebnisse werden in Fallanalysen dargestellt und diskutiert. Die Ergebnisse der Aus¬wertung verdeutlichen, dass das Themenfeld ‚Ernährung und Klimaschutz‘ im Unterrichts¬geschehen verankert ist und im Zuge dessen wird der sensible Umgang mit verschiedenen Studien und Studienergebnissen angesprochen. Alle befragten Personen wollen im Zuge der Widersprüchlichkeit und Komplexität des Themenfeldes die Schüler*innen in Meinungsbildung und im sensiblen Umgang mit Daten schulen. Dies zeigt, dass im Zuge des Studiums und der Lehrtätigkeit auf diesen Aspekten ein Hauptaugenmerk liegt. Ebenso ist ersichtlich, dass die Komplexität und Kontroversität sowohl im fachpraktischen als auch im fachtheoretischen Unterrichtsgeschehen von Bedeutung ist.

Aus diesem Grund beschäftigt sich diese Masterarbeit mit der Frage wie ein Literaturunterricht aussieht, der im Sinne der Bildungsge-rechtigkeit die Lesekompetenz aller SchülerInnen fördert und nachhaltig die Lust am Lesen weckt. Am Beispiel der Romane Spaltkopf und Dazwischen:Ich von Julya Rabinowich wird gezeigt, wie im Literaturunterricht eine Trendwende eingeläutet werden kann. Zu diesem Zweck werden die beiden Romane auf folgende Forschungsfrage hin untersucht: Auf welche Weise werden kulturelle Aspekte des Lebens in einer Migrationsgesellschaft in den ausge-wählten Werken thematisiert und wie können diese im Litertaturunterricht genutzt werden, um ein gelingendes gesellschaftliches Miteinander zu fördern? Einen wesentlichen Schritt stellt die Vermittlung eines philologisch-hermeneutischen Literaturverständnisses im Deutschunterricht (DaF, DaZ, DaM) und somit die Abwendung vom Le-sen als zweckgebundener und zielorientierter Tätigkeit dar. Im Mittelpunkt des Literaturun-terrichts steht die Kulturtechnik Lesen. Sie bereitet Vergnügen, ermöglicht den Blick in fremde Welten, initiiert Diskussionen, regt zur Selbstreflexion an und misst dem persönli-chen Leseerlebnis mehr Bedeutung bei. Ein Literaturunterricht, der diese Ziele verfolgt, setzt sich mit der Literarizität von Sprache auseinander. Neben dem Inhalt werden so auch sprachästhetische, formale und poetische Merkmale von Sprache zum Unterrichtgegenstand ernannt. Sprache, Literatur und Kultur sind untrennbar miteinander verbunden. Die kulturwissenschaftliche Öffnung der Literaturwissenschaften und der Landeskunde DaF/DaZ haben dazu beigetragen, dass Literatur in dem größeren kulturellen Kontext, aus dem sie hervorgeht und den sie mitgestaltet, betrachtet wird. Dieses Potential gilt es im Unterricht zugunsten der rassismuskritischen Bildungsarbeit zu nutzen, indem Literatur auf das Vorhandensein von rassistischen Diskursen, hierarchischen Strukturen und diskriminierenden Denkweisen unter-sucht wird. Rassismussensibler Literaturunterricht trägt dazu bei, dass Othering-Prozesse, die z.B. durch eine Unterscheidung zwischen SchülerInnen mit und ohne Migrationshintergrund ausgelöst werden, erkannt werden und ihnen mit wirksamen Gegenstrategien begegnet wird.

description: We create supercurrents in annular two-dimensional Bose gases through a temperature quench of the normal-to-superfluid phase transition. We detect the amplitude and the chirality of these supercurrents by measuring spiral patterns resulting from the interference of the cloud with a central reference disk. These measurements demonstrate the stochastic nature of the supercurrents. We further measure their distribution for different quench times and compare it with the predictions based on the Kibble-Zurek mechanism.

description: The detection of O- and B-type stars with extremely low-mass companions is very important for understanding the formation and evolution of binary stars. However, their finding remains a challenge because the low-mass components in such systems contribute such small flux to the total. During the searching for pulsations among O- and B-type stars by using the TESS data, we found two short-period and B-type (B9) eclipsing binaries with orbital periods of 1.61613 and 2.37857 days. Photometric solutions of the two close binaries were derived by analyzing the TESS light curves with the W-D method. It is discovered that both of them are detached binaries with extremely low mass ratios of 0.067(2) for TIC 260342097 and 0.140(3) for TIC 209148631, respectively. The determined mass ratio indicates that TIC 260342097 is one of the lowest mass ratios among known B-type binary systems. We showed that the two systems have total eclipses with a broad and flat secondary minimum, suggesting that the photometric parameters could be derived reliably. The absolute parameters of the two binaries are estimated and it is found that the secondary components in the two systems are over-luminous and over-size when compared with the normal low-mass and cool main-sequence (MS) stars. These findings may imply that the two systems are composed of a B-type MS primary and a cool pre-MS secondary with orbital periods shorter than 2.5 days. They are valuable targets to test theories of binary star formation and evolution.

description: The accretion flow around X-ray pulsars with a strong magnetic field is funnelled by the field to relatively small regions close to the magnetic poles of the neutron star (NS), the hotspots. During strong outbursts regularly observed from some X-ray pulsars, the X-ray luminosity can be so high, that the emerging radiation is able to stop the accreting matter above the surface via radiation-dominated shock, and the accretion column begins to rise. This border luminosity is usually called the "critical luminosity". Here we calculate the critical luminosity as a function of the NS magnetic field strength $B$ using exact Compton scattering cross section in strong magnetic field. Influence of the resonant scattering and photon polarization is taken into account for the first time. We show that the critical luminosity is not a monotonic function of the B-field. It reaches a minimum of a few 10^{36} erg s^{-1} when the cyclotron energy is about 10 keV and a considerable amount of photons from a hotspot have energy close to the cyclotron resonance. For small B, this luminosity is about 10^{37} erg s^{-1}, nearly independent of the parameters. It grows for the B-field in excess of 10^{12} G because of the drop in the effective cross-section of interaction below the cyclotron energy. We investigate how different types of the accretion flow and geometries of the accretion channel affect the results and demonstrate that the general behaviour of the critical luminosity on B-field is very robust. The obtained results are shown to be in a good agreement with the available observational data and provide a necessary ground for the interpretation of upcoming high quality data from the currently operating and planned X-ray telescopes.

description: In this paper, locally repairable codes with all-symbol locality are studied. Methods to modify already existing codes are presented. Also, it is shown that with high probability, a random matrix with a few extra columns guaranteeing the locality property, is a generator matrix for a locally repairable code with a good minimum distance. The proof of this also gives a constructive method to find locally repairable codes. Constructions are given of three infinite classes of optimal vector-linear locally repairable codes over an alphabet of small size, not depending on the size of the code.

description: Cardy has recently observed that certain carefully tuned states of 1+1 CFTs on a timelike strip are periodic with period set by the light-crossing time. The states in question are defined by Euclidean time evolution of conformal boundary states associated with the particular boundary conditions imposed on the edges of the strip. We explain this behavior, and the associated lack of thermalization, by showing that such states are Lorentz-signature conformal transformations of the strip ground state. Taking the long-strip limit implies that states used to model thermalization on the Minkowski plane admit non-thermal conformal extensions beyond future infinity of the Minkowski plane, and thus retain some notion of non-thermal behavior at late times. We also comment on the holographic description of these states.

How well is our universe described by an FLRW model?

description: Extremely well! In the $Λ$CDM model, the spacetime metric, $g_{ab}$, of our universe is approximated by an FLRW metric, $g_{ab}^{(0)}$, to about 1 part in $10^4$ or better on both large and small scales, except in the immediate vicinity of very strong field objects, such as black holes. However, derivatives of $g_{ab}$ are not close to derivatives of $g_{ab}^{(0)}$, so there can be significant differences in the behavior of geodesics and huge differences in curvature. Consequently, observable quantities in the actual universe may differ significantly from the corresponding observables in the FLRW model. Nevertheless, as we shall review here, we have proven general results showing that---within the framework of our approach to treating backreaction---the large matter inhomogeneities that occur on small scales cannot produce significant effects on large scales, so $g_{ab}^{(0)}$ satisfies Einstein's equation with the averaged stress-energy tensor of matter as its source. We discuss the flaws in some other approaches that have suggested that large backreaction effects may occur. As we also will review here, with a suitable "dictionary," Newtonian cosmologies provide excellent approximations to cosmological solutions to Einstein's equation (with dust and a cosmological constant) on all scales. Our results thereby provide strong justification for the mathematical consistency and validity of the $Λ$CDM model within the context of general relativistic cosmology.

description: We determined the spin-transport properties of Pd and Pt thin films by measuring the increase in ferromagnetic resonance damping due to spin-pumping in ferromagnetic (FM)-nonferromagnetic metal (NM) multilayers with varying NM thicknesses. The increase in damping with NM thickness depends strongly on both the spin- and charge-transport properties of the NM, as modeled by diffusion equations that include both momentum- and spin-scattering parameters. We use the analytical solution to the spin-diffusion equations to obtain spin-diffusion lengths for Pt and Pd. By measuring the dependence of conductivity on NM thickness, we correlate the charge- and spin-transport parameters, and validate the applicability of various models for momentum-scattering and spin-scattering rates in these systems: constant, inverse-proportional (Dyakanov-Perel), and linear-proportional (Elliot-Yafet). We confirm previous reports that the spin-scattering time can be shorter than the momentum scattering time in Pt, and the Dyakanov-Perel-like model is the best fit to the data.
