title: Tablets im DaF-Unterricht
Creators: name: Steger, Melanie Barbara
Year: 2017

description: In einer Zeit, in der die Digitalisierung immer weiter voranschreitet, müssen auch Vorgehensweisen im Unterricht überdacht bzw. neu konzipiert werden. Tablets bie-ten die Möglichkeit, neue Perspektiven im Unterricht zu eröffnen und einen ande-ren Zugang zum Lernen zu gewährleisten. Lehrende stehen vor neuen Herausfor-derungen, wenn sie einem modernen Unterricht gerecht werden wollen: Mobile Endgeräte müssen zielführend eingesetzt werden, d.h. Aktivitäten, die mit Tablets durchgeführt werden, müssen didaktisch gut in das Gesamtbild des Unterrichts ein-gebettet werden, damit Lernziele erreicht werden. Durch eine quantitative Befragung mittels Online-Fragebogen konnte ein Quer-schnitt über die Sichtweisen der Lehrenden an weltweiten Goethe-Instituten zur Verwendung von Tablets im DaF-Unterricht erhoben werden. Es wurden Einsatz-möglichkeiten und Potenziale, aber auch Herausforderungen bzgl. Tablets im Un-terricht identifiziert und auch die technischen und methodischen Kompetenzen der Lehrenden erfragt. Zusammenfassend kann gesagt werden, dass es notwendig ist, Weiterbildungsan-gebote für Lehrende zu ermöglichen, damit die Potenziale, die Tablets für den Un-terricht bieten können, noch mehr ausgeschöpft werden und Lehrende dazu ermu-tigt werden, Tablets in ihren Unterricht zu integrieren. Dadurch können die medien-didaktischen Kompetenzen von Lehrenden erweitert werden, wodurch ein hand-lungsorientierter Unterricht basierend auf der Lebenswelt der Lernenden stattfinden kann.

description: The thesis project originally approved was a translation, with critical comment, of Eduard Spranger's Lebensformen, a work which no English or American publisher had undertaken to introduce to the English-speaking public. It was discovered, however, that an English translation made by Mr. Paul J.W. Pigors of Harvard University had been published in Germany under the title Types of Men. Accordingly the plan of the present study was changed in favor of a critique of Spranger's basic teachings, to be made from the specific point of view indicated in the title, with especial reference to the educational needs of contemporary America.
IS MY ALEXA HAPPY WITH ME? ATTRIBUTIONS OF EMOTIONAL DISPLAYS IN HUMAN-COMPUTER INTERACTIONS

description: Virtual assistants such as Amazon's Alexa can emulate a variety of emotions in their spoken feedback to user requests. The persuasive impact of these emotional displays depends on the inferences individuals make about these emotional displays. This dissertation investigates a class of inferences –attributions of cause to a virtual assistant's emotional display –which individuals use as social information about computer-interactants. The project hypothesized that three key factors influence individuals' attributions of cause to virtual assistants' emotional displays. The first is general tendencies in peoples' attributions of virtual assistants' emotional displays. Second is the target of a virtual assistant's emotional display –the communicated object of their displayed emotional state. The final component is borrowed from Kelley's covariance theory of attribution –the distinctiveness with which a specific emotional display repeatedly co-occurs with plausible explanations for the emotional display. Four attributional outcomes were predicted based on combinations of emotional display targets and the distinctiveness of the emotional display's covariance with potential causes for the emotional display. Findings suggest that individuals first and foremost attribute virtual assistant's emotional displays to the virtual assistant rather than situational causes, that emotional display targets can influence attributions, and that further work is needed to assess the role of distinctiveness in attributions of virtual assistant's emotional displays.

description: We present a formula for the quantum entropy of supersymmetric five-dimensional spinning black holes in M-theory compactified on $CY_3$, i.e., BMPV black holes. We use supersymmetric localization in the framework of off-shell five dimensional $N=2$ supergravity coupled to $I = 1,\dots,N_V + 1$ off-shell vector multiplets. The theory is governed at two-derivative level by the symmetric tensor $\mathcal{C}_{IJK}$ (the intersection numbers of the Calabi-Yau) and at four-derivative level by the gauge-gravitational Chern-Simons coupling $c_I$ (the second Chern class of the Calabi-Yau). The quantum entropy is an $N_V + 2$-dimensional integral parameterised by one real parameter $φ^I$ for each vector multiplet and an additional parameter $φ^0$ for the gravity multiplet. The integrand consists of an action governed completely by $\mathcal{C}_{IJK}$ and $c_{I}$, and a one-loop determinant. Consistency with the on-shell logarithmic corrections to the entropy, the symmetries of the very special geometry of the moduli space, and an assumption of analyticity constrains the one-loop determinant up to a scale-independent function $f(φ^0)$. For $f=1$ our result agrees completely with the topological M-theory conjecture of Dijkgraaf, Gukov, Nietzke, and Vafa for static black holes at two derivative level, and provides a natural extension to higher derivative corrections. For rotating BMPV black holes, our result differs from the DGNV conjecture at the level of the first quantum corrections.

description: Einstein-Weyl geometry is a triple (D,g,w), where D is a symmetric connection, [g] is a conformal structure and w is a covector such that: (i) connection D preserves the conformal class [g], that is, Dg=wg; (ii) trace-free part of the symmetrised Ricci tensor of D vanishes. Three-dimensional Einstein-Weyl structures arise naturally on solutions of second-order dispersionless integrable PDEs in 3D. In this context, [g] coincides with the characteristic conformal structure and is therefore uniquely determined by the equation. On the contrary, the covector w is a somewhat more mysterious object, recovered from the Einstein-Weyl conditions. We demonstrate that, for generic second-order PDEs (for instance, for all equations not of Monge-Ampere type), the covector w is also expressible in terms of the equation, thus providing an efficient dispersionless integrability test. The knowledge of g and w provides a dispersionless Lax pair by an explicit formula which is apparently new. Some partial classification results of PDEs with Einstein-Weyl characteristic conformal structure are obtained. A rigidity conjecture is proposed according to which for any generic second-order PDE with Einstein-Weyl property, all dependence on the 1-jet variables can be eliminated via a suitable contact transformation.

description: Thouless pumping is a fundamental instance of quantized transport, which is topologically protected. Although its theoretical importance, the adiabaticity condition is an obstacle for further practical applications. Here, focusing on the Rice-Mele model, we provide a family of finite-frequency examples that ensure both the absence of excitations and the perfect quantization of the pumped charge at the end of each cycle. This family, which contains an adiabatic protocol as a limiting case, is obtained through a mapping onto the zero curvature representation of the Euclidean sinh-Gordon equation.

description: Os adolescentes são um grupo à partida saudável e que recorre pouco aos serviços de saúde. Na adolescência, apesar de a morbilidade ser elevada, a mortalidade é baixa. Os desenvolvimentos físico, emocional e psicológico que caracterizam a adolescência, fazem parte de um percurso cheio de oportunidades mas também com alguns riscos. Os pediatras podem ter um papel de relevo na ajuda ao adolescente para que se mantenha saudável e para que percorra esta caminhada até entrar na vida adulta» tirando o máximo partido dos seus recursos sem se envolver em demasiados riscos. Os Serviços de Saúde devem dar resposta às necessidades de saúde dos adolescentes de um modo integrado e proporcionando um ambiente amigável. A competência técnica deve ser acompanhada de respeito e sensibilidade para compreender a realidade de cada adolescente e permitir descobrir os problemas subjacentes que possam não ser a causa imediata de vinda à consulta. O objectivo deste estudo foi descrever o funcionamento de uma Consulta de Adolescentes de um Hospital Universitário e avaliar os últimos cinco anos do seu funcionamento.

description: The identification and description of point sources is one of the oldest problems in astronomy; yet, even today the correct statistical treatment for point sources remains one of the field's hardest problems. For dim or crowded sources, likelihood based inference methods are required to estimate the uncertainty on the characteristics of the source population. In this work, a new parametric likelihood is constructed for this problem using Compound Poisson Generator (CPG) functionals which incorporate instrumental effects from first principles. We demonstrate that the CPG approach exhibits a number of advantages over Non-Poissonian Template Fitting (NPTF) - an existing method - in a series of test scenarios in the context of X-ray astronomy. These demonstrations show that the effect of the point-spread function, effective area, and choice of point-source spatial distribution cannot, generally, be factorised as they are in NPTF, while the new CPG construction is validated in these scenarios. Separately, an examination of the diffuse-flux emission limit is used to show that most simple choices of priors on the standard parameterisation of the population model can result in unexpected biases: when a model comprising both a point-source population and diffuse component is applied to this limit, nearly all observed flux will be assigned to either the population or to the diffuse component. A new parametrisation is presented for these priors which properly estimates the uncertainties in this limit. In this choice of priors, CPG correctly identifies that the fraction of flux assigned to the population model cannot be constrained by the data.

The utility of forward exchange

description: The feeling has been expressed that the literature devoted exclusively to the subject of forward exchange in meager and, in fact, most inadequate in view of the importance of the subject. While it appears that in the past the writings in this field have been especially limited in the case of works in the English language, the situation has been remedied in considerable degree by the publication in 1937 of the definitive work of Dr. Paul Einzig. While it is not intended that this thesis should attempt to be a definitive work, even of the American point of view, it is hoped that it may be a useful exposition of the subject of forward exchange within moderate size limitations and written so as to be understandable to the average banker or business man who, although not engaged in international commerce, may be interested in those aspects of finance of international character which impinge upon and indirectly affect the internal economy of which he is a part. In short, it is hoped to set forth what forward exchange is, how it works, and its possibilities and limitations.

description: The problem of the real-time multiple-input multiple-output (MIMO) array control when requirements on capacity performance, out-of-cell interference, and computational efficiency are simultaneously enforced is addressed by means of an innovative hybrid beamforming technique. The synthesis of the excitations of the MIMO system is first re-formulated as that of matching an ideal "hybrid" pattern fitting capacity or low-interference constraints along the angular coordinates. Then, a non-iterative processing scheme is derived for each MIMO beam where numerically-efficient synthesis techniques are profitably combined. Representative results, from an extensive numerical validation, are discussed to show, also comparatively, the advantages and the current limitations of the proposed synthesis method when dealing with different propagation scenarios, number of transmitters/receivers, and noise levels.

description: Dedicated spectrometers for terahertz radiation with [0.3, 30] THz frequencies using traditional optomechanical interferometry are substantially less common than their infrared and microwave counterparts. This paper presents the design and initial performance measurements of a tabletop Fourier transform spectrometer (FTS) for multi-terahertz radiation using infrared optics in a Michelson arrangement. This is coupled to a broadband pyroelectric photodetector designed for [0.1, 30] THz frequencies. We measure spectra of narrowband and broadband input radiation to characterize the performance of this instrument above 10 THz, where signal-to-noise is high. This paves the groundwork for planned upgrades to extend below 10 THz. We also briefly discuss potential astroparticle physics applications of such FTS instruments to broadband axion dark matter searches, whose signature comprises low-rate monochromatic photons with unknown frequency.

description: Objectivos: O objectivo deste estudo foi o de avaliar a sobrevivência, frequência de recidivas e sequelas em crianças com Doença de Hodgkin tratadas neste serviço nos últimos vinte anos.

Material e Métodos: Foi efectuado um estudo de coorte retrospectivo. Foram analisados os seguintes parâmetros: idade, sexo, data do diagnóstico, tiemoglobina (Hb) (g/dl): <10,5 e > 10,5, velocidade de sedimentação (VS): > 40 mm/h e <40 mm/h, tipo histológico, estádio da doença, tipo de tratamento, resposta inicial à quimioterapia (QT), toxicidade aguda, complicações tardias» recidivas e estado actual.

Sobrevivência livre de doença (SLD) e sobrevivência global (SG) foram determinadas desde a data do diagnóstico até à recidiva ou morte por qualquer causa, respectivamente. Para avaliar a importância das variáveis clínicas foi utilizado o teste de Log-Rank (resultado significativo p<0,05).

Resultados: No Serviço de Pediatria entre Abril de 1983 e Abril de 2002 foram tratadas cinquenta e sete crianças (33 do sexo masculino e 24 do sexo feminino) com idades compreendidas entre 2 e 14 anos (mediana 12 anos), portadoras de Doença de Hodgkin(DH). De acordo com a classificação de Ann Arbor, 15 doentes apresentavam DH estádio 1 (26%), 23 estádio 11 (40%), 14 estádio Hl(25%) e 5 doentes apresentavam DH estádio IV (9%). Os sintomas B estavam presentes em 15 doentes (26%). De acordo com a classificação de RYE 36 crianças tinham esclerose nodular (64%), 11 celularidade mista (20%) e 9 predomínio linfocítico (16%). De 1983 a 1998 foram tratadas 25 crianças de acordo com o protocolo ChlVPP/RT e desde 1999 18 crianças de acordo com o protocolo da SFOP MDH 90. Catorze crianças foram tratadas com outros protocolos. Radioterapia foi aplicada em 52 crianças (91%). Verificou-se remissão completa em 91% dos casos. Verificaram-se 2 óbitos (12 meses e 3 anos após o diagnóstico, por DH e leucemia mieloblástica aguda respectivamente). Quatro doentes apresentaram neoplasias secundárias, 4 tiveram hipotiroidismo e 3 rapazes infertilidade. A primeira recaída verificou-se 40 meses após o início da terapêutica com ChlVPP e 42 meses no grupo da SFOP MDH 90.

Conclusão: No nosso grupo de 57 doentes, com um tempo mediano de seguimento de 67 meses (11 - 239 meses), a sobrevivência livre de doença foi de 89% e a sobrevivência global foi de 97% aos 5 anos. A maioria das crianças com DH foi curada sem importantes efeitos adversos.

description: We use the gauge/gravity correspondence to show that in its context there appear Landau levels when studying the excitations of the fundamental degrees of freedom of a strongly coupled plasma subject to a magnetic field of arbitrary intensity. We work in the phase where mesons are melted by embedding a D7-brane in the 10D uplift that we construct for the 5D background associated to a magnetic brane. By studying the dependence of the lowest quasinormal frequency on both, the intensity of the magnetic field and the Landau level, we corroborate that the energy behaves as expected for dissociating Landau levels. The reconstruction of the impact of the magnetic field on the stability of the quasinormal modes allows us to identify inverse magnetic catalysis for intensities of the field bellow a certain value, and magnetic catalysis for those above it.
description: This version includes the calculation of the quasinormal modes of the dual scalar excitations, and presents the behavior of their energy as evidence that the evolution of such modes describes dissociating Landau levels. The study of the width of the modes was also added, showing that inverse magnetic catalysis and magnetic catalysis occur for different ranges of the magnetic field
The Contrasting Role of Single-cell Studies in the Theoretical Debate on Determinism in Molecular Biology
Creators: name: Heams, Thomas
Publisher: name: Organisms
Year: 2023

description: In experimental biology, the last three decades have seen a flood of techniques dedicated to study biological phenomena at the single-cell level, and this article aims to reflect on how these technical advances can contribute to the renewal of theoretical perspectives in biology. The case studied here is that of the critique of the genetic determinism of molecular biology. The demonstration of unpredictability in gene expression at the single-cell level, a phenomenon known as stochastic gene expression, even in clonal populations, initially appeared to be a decisive indication that cells do not actually behave as predicted by deterministic frameworks. However, single-cell techniques have also revealed other sources of genetic variation that nuance this picture. The role of single-cell studies thus appears contrasted, and can be used to support or challenge the paradigm of genetic determinism (GDP). This opens up a more general debate on the practical ability of molecular biologists to criticize their own paradigms.

Uma relação de confiança, transaccionalmente positiva e gratificante entre mãe e bebé gera autoconfiança e sentido de competência em cada nova relação no espectro progressivamente mais largo dos vínculos e das transacções.Resiliência é, assim, algo que também se ajuda a construir num dos seus pólos através dos condicionantes estruturais que geram o contexto da vida e que, no espírito da nossa reflexão representam, afinal, a grande convergência das forças do desenvolvimento.Os três pilares fundamentais da resiliência podem ser estilizadamente resumidos em três auto-sentimentos, porém referidos à relação com os outros, esperadamente significativos: "Eu sou, Eu quero, Eu posso".Os valores que estas linhas de força significam para a criança serão, fundamentalmente, os esteios do desenvolvimento humano.

description: Existing grasp synthesis methods are either analytical or data-driven. The former one is oftentimes limited to specific application scope. The latter one depends heavily on demonstrations, thus suffers from generalization issues; e.g., models trained with human grasp data would be difficult to transfer to 3-finger grippers. To tackle these deficiencies, we formulate a fast and differentiable force closure estimation method, capable of producing diverse and physically stable grasps with arbitrary hand structures, without any training data. Although force closure has commonly served as a measure of grasp quality, it has not been widely adopted as an optimization objective for grasp synthesis primarily due to its high computational complexity; in comparison, the proposed differentiable method can test a force closure within milliseconds. In experiments, we validate the proposed method's efficacy in 6 different settings.

description: As dificuldades de aprendizagem são uma das causas mais frequentes de envio às consultas de desenvolvimento sendo a sua etiologia multifactoríal.

A baixa estatura (BE) é na maioria das vezes uma situação benigna mas pode também ser o único sinal de várias patologias entre as quais os síndromes genéticos.

Os autores apresentam o caso de uma criança com 9 anos sinalizada à consulta de desenvolvimento aos 7 anos por dificuldades de aprendizagem e BE

A evolução estatural foi sempre inferior ao percentil 5, sendo a velocidade de crescimento nos últimos anos inferior a quatro centímetros por ano; pais sem BE.

Na primeira consulta foram constatadas dificuldades específicas de aprendizagem, nomeadamente na visiomotricidade, estruturação espacial e compreensão da linguagem. Confirmada a BE, com uma idade estatural de 4.5 anos, inferior à idade óssea, O cariótipo obtido foi: 45, X apresentando algumas células o cromossoma X cm anel. Concluiu-se por um Síndrome de Turner (ST) com cromossoma X em anel.

A maioria dos indivíduos com ST não têm atraso mental mas têm dificuldades específicas de aprendizagem. Os autores alertam para possibilidade deste diagnóstico em qualquer criança sexo feminino com uma BE de causa desconhecida, sobretudo se associada a um perfil neuropsicológico característico e cujo fenótipo não seja incompatível com o ST.

description: Evolutions of local Hamiltonians in short times are expected to remain local and thus limited. In this paper, we validate this intuition by proving some limitations on short-time evolutions of local time-dependent Hamiltonians. We show that the distribution of the measurement output of short-time (at most logarithmic) evolutions of local Hamiltonians are \emph{concentrated} and satisfy an \emph{isoperimetric inequality}. To showcase explicit applications of our results, we study the \textsc{MaxCut} problem and conclude that quantum annealing needs at least a run-time that scales logarithmically in the problem size to beat classical algorithms on \textsc{MaxCut}. To establish our results, we also prove a Lieb-Robinson bound that works for time-dependent Hamiltonians which might be of independent interest.

description: We investigate the quantum spin liquid (QSL) ground state of anisotropic Kitaev model with antiferromagnetic (AFM) coupling under the $[001]$ magnetic field with the finite-temperature Lanczos method (FTLM). In this anisotropic AFM Kitaev model with $K_{X}=K_{Y}$, $K_{X}+K_{Y}+K_{Z}=-3K$, and $K_{Z}<-K$, with magnetic field increasing, the gapped QSL experiences a transition to a gapless QSL at $h_{c1}=gμ_{B}H_{z1}/K$, to another gapless QSL with $C_{6}$ rotational symmetry at $h_{c2}$, and to a new $U(1)$ gapless QSL between $h_{c3}$ and $h_{c4}$, respectively. These indicate that magnetic field could first turn the anisotropic gapped or gapless QSL back into the isotropic $C_{6}$ gapless one and then make it to undergo the similar evolution as the isotropic case. Moreover, the critical magnetic fields $h_{c1}$, $h_{c2}$, $h_{c3}$, and $h_{c4}$ come up monotonically with the increasing Kitaev coupling; this suggests that the magnetic field can be applied to the modulation of the anisotropic Kitaev materials.

description: The parameterized entanglement monotone, the $q$-concurrence, is also a reasonable parameterized entanglement measure. By exploring the properties of the $q$-concurrence with respect to the positive partial transposition and realignment of density matrices, we present tight lower bounds of the $q$-concurrence for arbitrary $q\geqslant 2$. Detailed examples are given to show that the bounds are better than the previous ones.

description: Os autores apresentam o caso clínico de um lactente de 9 meses, previamente saudável, que se apresenta com um quadro de cardiomiopatia aguda fulminante rapidamente progressiva e fatal. O quadro de insuficiência cardíaca grave surge no contexto de uma doença febril e é acompanhado de hípoglicémia grave. O exame histológico post-mortem de músculo cardíaco não é consistente com a hipótese inicial de miocardite aguda. Na microscopia electrónica identificam-se mitocôndrias gigantes e formações anormais das cristas mitocondriais.

As doenças mitocondriais e defeitos do metabolismo energético cardíaco são causas cada vez mais reconhecidas de cardiomiopatias.

Chama-se a atenção para a necessidade de realizar um screening metabólico e preservar amostras de tecidos na cardiomiopatia aguda em crianças.

description: O edema agudo hemorrágico do lactente é uma vasculite de etiologia desconhecida, que atinge crianças com menos de 2 anos, caracterizada clinicamente pela existência de lesões purpúricas localizadas nas extremidades e face, com edema das mãos e pés. Tem inicio súbito, curso benigno e evolui espontaneamente para a cura. Embora o quadro clínico seja típico, por vezes coloca problemas de diagnóstico diferencial, pelo que o seu reconhecimento é importante em termos de investigação e terapêutica.Os autores apresentam 2 casos de edema agudo hemorrágico do lactente, diagnosticados no último ano.

description: We study a time minimization problem on the group of motions of a plane with admissible control in a half-disk. The considered control system describes a model of a car that can move forward on a plane and turn in place. Optimal trajectories of this system are used in image processing for the detection of salient lines. In particular, such trajectories are used in the analysis of medical images when searching for blood vessels in photos of the human retina. The problem is of interest in geometric control theory as a model example in which the set of admissible controls contains zero at the boundary. We prove complete controllability and the existence of optimal trajectories. By analyzing the Hamiltonian system of Pontryagin maximum principle we derive explicit formulas for extremal controls and trajectories. The optimality of extremals is partially investigated. The structure of optimal synthesis is described.

description: Die vorliegende Masterarbeit befasst sich mit zwischensprachlichen Einflüssen der Erst- und Zweitsprache auf den Drittspracherwerb. Es werden schriftliche Texte von chinesischsprachigen Deutschlernenden auf Interferenzen aus dem Chinesischen und dem Englischen untersucht. Die theoretische Basis bilden Modelle und Hypothesen aus der Mehrsprachigkeitsforschung. Als Methode wurde die Fehleranalyse gewählt, die durch die Entwicklung eines eigenen Kriterienrasters an den Untersuchungsgegenstand angepasst wurde. Die Arbeit teilt sich in einen theoretischen und einen empirischen Teil. Der theoretische Teil gibt einen Überblick über die Erkenntnisse der Mehrsprachigkeitsforschung mit einem Fokus auf den Drittspracherwerb. Außerdem werden die für die Arbeit interessanten Sprachenpaare, Chinesisch und Deutsch bzw. Deutsch und Englisch, in einem kontrastiven Sprachvergleich gegenübergestellt. Zum Schluss wird auf die Begriffe Fehler und Abweichung eingegangen. Im empirischen Teil werden die Abweichungen in den Texten zuerst identifiziert, mithilfe des Kriterienrasters kategorisiert und als letzten Schritt auf ihre Ursache bzw. Herkunft hin analysiert. Das Ziel dieser Masterarbeit ist, die Frage nach dem Einfluss von zuvor gelernten Sprachen auf die Zielsprache zu klären.---1 CD-ROM in der Printversion vorhanden
International Treaties between Czechoslovakia and Germany

description: International relations between modern States have become so complicated, that it is necessary, in order to avoid expensive controversies, to include their mutual obligations in the express terms of international treaties. These international treaties or conventions may be defined as agreements or contracts between two or more States, usually negotiated for the purpose of creating, modifying, or extinguishing mutual rights and reciprocal obligations. For their validity it is essential that the contracting parties have power over the subject matter, that consent be reciprocally and regularly given and that the object of the treaty be possible and lawful under the accepted principles of international law. They are merely evidence of international agreements but in some cases constitute a codification of existing usage and may become a source of international law. They are, however, always compulsory upon the signatory States and form a rule for the parties.The treaty regime between Czechoslovakia and Germany is a good example of such a rapidly growing network of international treaties between two independent States. It shows how cooperation of mankind en miniature works in practice, how legal bases for different interests are worked out, and at the same time it is a dynamic illustration of the application of the principles of supra-national law. In order to attack seriously its important factors, one should include the study of treaties and treaty systems of modern States.It is the purpose of this thesis to investigate what the treaty relations between Czechoslovakia and Germany are and by a brief analysis of some fact concerning international law, or international relations, respectively, to make a slight contribution to the work on such an immensely important subject as international treaties.
A parabolic Harnack principle for balanced difference equations in random environments

description: We consider difference equations in balanced, i.i.d. environments which are not necessary elliptic. In this setting we prove a parabolic Harnack inequality (PHI) for non-negative solutions to the discrete heat equation satisfying a (rather mild) growth condition, and we identify the optimal Harnack constant for the PHI. We show by way of an example that a growth condition is necessary and that our growth condition is sharp. Along the way we also prove a parabolic oscillation inequality and a (weak) quantitative homogenization result, which we believe to be of independent interest.

description: Multicavity Klystron (MCK) is a high power microwave (HPM) vacuum electronic device used to amplify radio-frequency (RF) signals with numerous applications, including radar, radio navigation, space communication, television, radio repeaters, and charged particle accelerators. The microwave-generating interactions in klystrons take place in resonant cavities at discrete locations along the beam. Importantly, there is no electromagnetic coupling between cavities, they are coupled only by the bunched electron beam, which drifts from one cavity to the next. We advance here an analytic theory of MCKs operating in voltage amplification mode associated with the maximal gain. This theory features in particular exact formulas for the MCK instability frequencies, its dispersion relations and optimal values of the MCK parameters providing for maximal gain.
