description: A powerful high voltage generator was built that can produce discharges of about one meter. This high voltage transformer can be driven in such a way that audible pressure waves can be generated by the electrical discharges. Normal high-voltage measuring devices cannot be used for this sensitive system. Therefore, two measuring methods were developed.

description: Модернизация муниципального управления с учётом внедрения инновационных методов развития муниципального образования требует новых походов к планированию работы органов местного самоуправления. Специфика муниципального управления определяется прежде всего особенностями муниципального образования как объекта управления, включающего все стороны жизни людей. К примеру, говоря об эффективности муниципального управления, невозможно ограничиться лишь экономической эффективностью, оставляя вне рассмотрения социальную, "нравственную" эффективность тех или иных управленческих решений.

description: In this paper, I will analyze the Japanese reception of Cubist Poems, a collection of experimental poetry published in 1914 by the Jewish-American painter Max Weber (1881‒1961). First, I will provide information on this little-known collection and its author. Then I will offer a general description of the structure of the field of cultural production in 1910s and 1920s Tokyo, a period that roughly corresponds to the reign of Emperor Taishō (1912‒1926). To do so, I will use a number of theoretical tools from the works of Pierre Bourdieu. Part of this article will be structured as a historical survey of the presentation of Cubist Poems in 1914‒1925 Japan. As will become clear, in the Japanese cultural world, Weber’s collection provoked an interest that was unparalleled in any other country, perhaps even in the English-speaking world. Finally, I will offer some interpretations of the characteristics of this reception and some hypotheses concerning its causes.

description: The upper critical field Hc2 is a fundamental measure of the pairing strength, yet there is no agreement on its magnitude and doping dependence in cuprate superconductors. We have used thermal conductivity as a direct probe of Hc2 in the cuprates YBa2Cu3Oy and YBa2Cu4O8 to show that there is no vortex liquid at T = 0, allowing us to use high-field resistivity measurements to map out the doping dependence of Hc2 across the phase diagram. Hc2(p) exhibits two peaks, each located at a critical point where the Fermi surface undergoes a transformation. The condensation energy obtained directly from Hc2, and previous Hc1 data, undergoes a 20-fold collapse below the higher critical point. These data provide quantitative information on the impact of competing phases in suppressing superconductivity in cuprates.

description: «Лингвистический поворот» в философии оказывает глубокое влияние на исследования в области лингвистики и преподавания языка. Благодаря упорядочению результатов исследований в области лингвистики и культурологии в последние десять лет, особенно в лингвокультурологии возникло много новых терминов и теорий, в частности языковой картины мира, лингвокультурологически значимой единицы, культурных пространств, языковой личности, когнитивной базы и т. д., все они это конкретные воплощения «лингвистического поворота». Полагается, что по существу концепт является основой для обсуждения этих новых терминов. Национальные концепты представляют собой фундаментальные единицы, создающие языковую картину мира, и составляющие ядро культурного пространства данной нации. Логоэпистемы, лингвокультуремы, прецедентные феномены и национально социокультурные стереотипы речевого общения являются овнешняемыми образами концептов. Опираясь на результаты исследования национальных концептов можно реализоваться точное определение языковых материалов обучения и составление целесообразных учебных пособий для преподавания языка и культуры. Более того на фоне родной культуры, использовать сравнительный метод т.е. сравнить один и то же концепт в родной и чужой культуре, что позволяет обучающимся глубинно воспринять чужую культуру тем самым способствует эффективно освоению иностранного языка.

A Priori Estimates for Monge-Ampere Equation and Applications
Creators: name: Chen, Haodi
Publisher: name: The Australian National University
Year: 2022

description: In this thesis we study different applications of the Monge-Ampere type equations. Chapter 1 is an introduction. In Chapter 2, we study the convergence rate of discrete Monge-Ampere type equation. In Chapter 3 we study the Lp-dual Minkowski problem. In Chapter 4 we study the asymptotic affine hyperspheres. The numerical solution to Monge-Ampere equation, in particular the Dirichlet problem has drawn much attentions in last 20 years. Different algorithms have been designed to simulate numerical solutions. We approximate the solution u by a sequence of convex polyhedra, which are generalised solutions to the Monge-Ampere type equation in the sense of Aleksandrov, and the associated Monge-Ampere measure are supported on a properly chosen grid in the domain. We derive the convergence rate estimates for the cases when f is smooth, Holder continuous and merely continuous in Chapter 2. Lp dual Minkowski problem is introduced by Lutwak-Yang-Zhang recently, which amounts to solving a class of Monge-Ampere type equations on the sphere. Our main purpose in Chapter 3 is to solve the Lp dual Minkowski problem in the case for all p > 0 studying of related parabolic flows. Also under these flows we obtain some uniqueness, smoothness and positivity results for the problem. We generalise a Blaschke-Santol`o type inequality, and applied the inequality in a variational method to obtain some existence and non-uniqueness results for the problem in the symmetric case. In Chapter 4, we study a singular Monge-Ampere type equation related to affine hyperspheres. We show the existence of solutions via regularization method, followed by the existence of asymptotic affine hyperspheres. Also, we study the regularity of this Monge-Ampere type equation and obtain the optimal graph regularity. The results are contained in the published papers.

description: We describe and characterize a method for estimating the pressure field corresponding to velocity field measurements, such as those obtained by using particle image velocimetry. The pressure gradient is estimated from a time series of velocity fields for unsteady calculations or from a single velocity field for quasi-steady calculations. The corresponding pressure field is determined based on median polling of several integration paths through the pressure gradient field in order to reduce the effect of measurement errors that accumulate along individual integration paths. Integration paths are restricted to the nodes of the measured velocity field, thereby eliminating the need for measurement interpolation during this step and significantly reducing the computational cost of the algorithm relative to previous approaches. The method is validated by using numerically-simulated flow past a stationary, two-dimensional bluff body and a computational model of a three-dimensional, self-propelled anguilliform swimmer to study the effects of spatial and temporal resolution, domain size, signal-to-noise ratio, and out-of-plane effects. Particle image velocimetry measurements of a freely-swimming jellyfish medusa and a freely-swimming lamprey are analyzed using the method to demonstrate the efficacy of the approach when applied to empirical data.

description: The formation of large-scale brain networks, and their continual refinement, represent crucial developmental processes that can drive individual differences in cognition and which are associated with multiple neurodevelopmental conditions. But how does this organization arise, and what mechanisms drive diversity in organization? We use generative network modeling to provide a computational framework for understanding neurodevelopmental diversity. Within this framework macroscopic brain organization, complete with spatial embedding of its organization, is an emergent property of a generative wiring equation that optimizes its connectivity by renegotiating its biological costs and topological values continuously over time. The rules that govern these iterative wiring properties are controlled by a set of tightly framed parameters, with subtle differences in these parameters steering network growth towards different neurodiverse outcomes. Regional expression of genes associated with the simulations converge on biological processes and cellular components predominantly involved in synaptic signaling, neuronal projection, catabolic intracellular processes and protein transport. Together, this provides a unifying computational framework for conceptualizing the mechanisms and diversity in neurodevelopment, capable of integrating different levels of analysis-from genes to cognition.

description: In order to investigate the relationship between weak amenability and the Haagerup property for groups, we introduce the weak Haagerup property, and we prove that having this approximation property is equivalent to the existence of a semigroup of Herz-Schur multipliers generated by a proper function. It is then shown that a (not necessarily proper) generator of a semigroup of Herz-Schur multipliers splits into a positive definite kernel and a conditionally negative definite kernel. We also show that the generator has a particularly pleasant form if and only if the group is amenable. In the second half of the paper we study semigroups of radial Herz-Schur multipliers on free groups. We prove that a generator of such a semigroup is linearly bounded by the word length function.

description: Critical ethical questions arise concerning whether studies among adolescents of new behavioral and biomedical HIV preventive interventions such as Pre-Exposure Prophylaxis (PrEP) should obtain parental permission. This paper examines the relevant regulations and ethical guidance concerning waivers of parental permission, and arguments for and against such waivers. Opponents of such waivers may argue that adolescent decision-making is “too immature” and that parents always have rights to decide how to protect their children. Yet requiring parental permission may put adolescents at risk, and/or limit adolescent participation, jeopardizing study findings' validity. This paper presents recommendations on when researchers and Institutional Review Boards (IRB) should waive parental permission, and what special protections should be adopted for adolescents who consent for themselves, e.g., assuring adolescent privacy and confidentiality, screening for capacity to consent, and identifying adolescents who are at elevated risk from study participation. We also present a series of specific areas for future research to design tools to help make these assessments, and to inform researcher and IRB decisions. These recommendations can help ensure that research is conducted that can aid adolescents at risk for HIV, while minimizing risks and protecting these individuals' rights as much as possible.
Mesoscale deformation and damage characterisation of woven fibre-reinforced composites
Creators: name: Holmes, John
Publisher: name: The Australian National University
Year: 2022

description: This work explores the deformation and damage behaviour of woven fibre-reinforced thermoplastic matrix composites. These composites are of interest to the automotive, aerospace and energy sectors due to their high specific strength, manufacturability and recyclability. However, the woven architecture complicates the mesoscale deformation behaviour and consequent damage development. Therefore, an improved understanding of this behaviour is necessary for enhanced performance prediction through modelling and simulation, and hence confidence in design application under load. Advanced characterisation techniques are required to acquire this data experimentally. Specifically, an investigation into the influence of weave architecture, deformation mode, fibre/matrix constituents and defects on damage progression and local deformation is needed. This work uses digital image and volume correlation (DIC/DVC) methods along with micro-computed tomography (micro-CT) to address this knowledge gap. Novel testing and characterisation techniques are developed through the thesis to advance knowledge of woven fibre-reinforced composites. This includes the development of new deformation mode testing to induce shear, tension and biaxial loading into composite laminates and to assess their deformation and damage development. Similarly, another new technique allows for the mesoscale topographical analysis of local weave surface deformation for tension, tension-torsion and hemispherical specimen geometries. Examination of internal deformation is also improved by an approach combining micro-CT with DIC and DVC. The latter technique enables a transition from macroscale and surface deformation characterisation to a detailed 3D understanding of the mechanisms and relationships between the woven microstructure and deformation. The techniques developed in this thesis are applied to a variety of materials with varying fibre (carbon, glass, aramid and self-reinforced), matrix (PP, PC, PEI and PEEK) and weave style (plain, twill and satin). Several key findings are made. First, weave architecture, including style and layer alignment, significantly influences mesoscale strain and topography and can be identified based on the deformation characteristics. Similarly, defects, including fibre waviness, varying volume fractions and voids, also alter the local deformation response. Defects and architecture can then be related to the location and progression of damage in the form of matrix cracking, delamination and fibre fracture. The detailed evidence provided by DIC, micro-CT and DVC of defects, deformation and damage for different loading modes and material compositions enables a deeper 3D understanding of material behaviour. This understanding provides the foundation for improved mesoscale composite digitalisation and hence enables future high-fidelity simulations with accurate geometry and boundary conditions for reliable numerical failure prediction.

It is shown that present mean-field approximation predicts some essential features of the experimentally observed dependence of the critical temperature on the coupling strength and a second - order quantum phase transition.In contrast to a recent prediction for atomic gases by Fred Cooper et. al., we find no superfluid state with zero condensate fraction.

description: Данное исследование является актуальным с точки зрения необходимости выявить сильные и слабые стороны политики дореволюционной России с целью применения положительного опыта в современной законотворческой деятельности. Современные процессы, происходящие во всем мире, свидетельствуют о необходимости создания действенного механизма защиты прав населения в случае каких-либо вооруженных конфликтов. Более того, XXI плюралистический век предоставил возможность пересмотреть некоторые положения относительно политики имперского периода. Цель: исследовать основные направления политики Российской империи в отношении защиты прав населения с возможностью апробации полученных выводов в нынешнем законотворческом процессе. Методология исследования – сравнительно-правовой, историко-правовой методы. В результате исследования автором обоснована необходимость рассматривать политику Российской империи накануне и в годы Первой мировой войны с разных точек зрения, выделять как положительные аспекты опыта защиты социальных прав населения, так и учитывать допущенные законодателем ошибки. При этом опыт Российской империи относительно защиты трудовых прав женщин, несовершеннолетних детей является скорее негативным, однако его также следует учитывать в правовом моделировании во избежание допущения повторения ошибок. Таким образом, автор приходит к выводу о противоречивости политики Российской империи в отношении защиты прав населения. С одной стороны, политика была направлена на проведение реформ и улучшение положения населения. С другой стороны, некоторые направления политики оказались стратегически ошибочными и привели к нарастанию социальной напряженности, которая в итоге привела к революционным действиям.

description: Due to the success of the bag-of-word modeling paradigm, clustering histograms has become an important ingredient of modern information processing. Clustering histograms can be performed using the celebrated $k$-means centroid-based algorithm. From the viewpoint of applications, it is usually required to deal with symmetric distances. In this letter, we consider the Jeffreys divergence that symmetrizes the Kullback-Leibler divergence, and investigate the computation of Jeffreys centroids. We first prove that the Jeffreys centroid can be expressed analytically using the Lambert $W$ function for positive histograms. We then show how to obtain a fast guaranteed approximation when dealing with frequency histograms. Finally, we conclude with some remarks on the $k$-means histogram clustering.

description: Эффект пандемии коронавируса явился разрушительным не только для мировой экономики и мировых финансовых систем, но и для международной цепочки поставок – закрытие границ и введение антиковидных мер вынудило страны резко ограничить уровень импорта и экспорта. Все эти факторы заставляют рассматривать COVID-19 как препятствие для осуществления международного обмена товарами и сотрудничества. Именно такое определение пандемии коронавируса даёт четкое представление о том, что наиболее серьезную угрозу сегодняшний кризис представляет для интеграционных систем, прежде всего, для Европейского Союза, в основе которого заложены свободы перемещения и торговли товарами, прямо противоположенные идеям “локдауна” и ограничений эпохи пандемии коронавируса.

description: We show that every unitary representation of a solvable discrete virtually nilpotent group G is quasidiagonal. Roughly speaking, this says that every unitary representation of G approximately decomposes as a direct sum of finite dimensional approximate representations. In operator algebraic terms we show that C*(G) is strongly quasidiagonal.

T Tauri stars

description: Veiling is ubiquitous at different wavelength ranges in classical T Tauri stars. The hot spot alone is not enough to explain the shallow photospheric infrared lines in accreting systems, and it suggests that another source contributes to the veiling in the near-infrared. The inner disk is often quoted as the additional emitting source to explain the infrared veiling. We used a sample of accreting stars observed with the CFHT/SPIRou spectrograph to measure the near-infrared veiling along the YJHK bands to understand its origin and time scale variability. We compared the computed veiling with accretion and inner disk diagnostics from photometric observations gathered in the literature. Our data provide further evidence that the veiling in the infrared increase with the wavelength, veiling growths from Y to K band for most of the targets in our sample, similar to results found in the literature. The infrared veiling agrees with near-infrared emission excess obtained using photometric data. However, we also find a linear correlation between the veiling and the accretion properties of the system, showing that accretion contributes to inner disk heating and, consequently, to the inner disk emission excess.

description: Studies reported a strong impact on mental health during the first wave of the COVID-19 pandemic in March–June, 2020. In this study, we assessed the impact of the pandemic on mental health in general and on schizotypal traits in two independent general population samples of the United Kingdom (May sample N: 239, October sample N: 126; participation at both timepoints: 21) and in two independent general population samples of Germany (May sample N: 543, October sample N: 401; participation at both timepoints: 100) using online surveys. Whereas general psychological symptoms (global symptom index, GSI) and percentage of responders above clinical cut-off for further psychological investigation were higher in the May sample compared to the October sample, schizotypy scores (Schizotypal Personality Questionnaire) were higher in the October sample. We investigated potential associations, using general linear regression models (GLM). For schizotypy scores, we found that loneliness, use of drugs, and financial burden were more strongly corrected with schizotypy in the October compared to the May sample. We identified similar associations for GSI, as for schizotypy scores, in the May and October samples. We furthermore found that living in the United Kingdom was related to higher schizotypal scores or GSI. However, individual estimates of the GLM are highly comparable between the two countries. In conclusion, this study shows that while the general psychological impact is lower in the October than the May sample, potentially showing a normative response to an exceptional situation; schizotypy scores are higher at the second timepoint, which may be due to a stronger impact of estimates of loneliness, drug use, and financial burden. The ongoing, exceptional circumstances within this pandemic might increase the risk for developing psychosis in some individuals. The development of general psychological symptoms and schizotypy scores over time requires further attention and investigation.

description: In response to a policy of the National Institutes of Health and requirements in the revised Common Rule, a protocol for a multisite study must be reviewed by a single institutional review board (IRB), rather than by the IRB at each study site. The goal of the single IRB approach is to increase the efficiency of IRB review of multisite research without jeopardizing protections for research subjects. Yet the extent to which these joint goals are being achieved is unclear. To better understand how single IRBs function, we recruited academic, government, and commercial single IRBs (N = 49) to participate in a study involving observation of protocol review meetings and/or interviews with their members, chairs, and administrators. Twenty (40.8%) agreed to participate, of which 50% agreed to both interviews and observation. While 81.8% (9/11) of academic and 50% (4/8) of government single IRBs participated in some way, only 23.3% (7/30) of commercial single IRBs did so. The four largest commercial single IRBs declined to participate. Because evaluation of single IRBs is important to inform development, implementation, monitoring, and refinement of federal policies, single IRBs should be encouraged to participate in research that examines how they function.

description: We consider quantum heat engines that operate between nonequilibrium stationary reservoirs. We evaluate their maximum efficiency from the positivity of the entropy production and show that it can be expressed in terms of an effective temperature that depends on the nature of the reservoirs. We further compute the efficiency at maximum power for different kinds of engineered reservoirs and derive a nonequilibrium generalization of the Clausius statement of the second law.

Generalised canonical basic sets for Ariki-Koike algebras

Subjects: subject: Representation Theory (math.RT)

description: Let H be a non semi-simple Ariki-Koike algebra. According to [18] and [14], there is a generalisation of Lusztig's a-function which induces a natural order (parametrised by a tuple m) on Specht modules. In some cases, Geck and Jacon have proved that this order makes unitriangular the decomposition matrix of H. The algebra H is then said to admit a "canonical basic set". We fully classify which values of m afford a canonical basic set for H and which do not. When this is the case, we describe these sets in terms of "twisted Uglov" or "twisted Kleshchev" multipartitions.

description: Questions arise concerning participants’ motives in risky studies, such as HIV vaccine trials (HVTs). We interviewed in-depth 20 gay/bisexual men. Participants described both altruistic and nonaltruistic motives. Altruistic motivations emerged primarily, with nine typologies: (a) cultural, (b) community related, (c) familial, (d) religious, (e) professional, (f) political (e.g., HIV activism), (g) moral (e.g., making up for past wrongs), (h) existential (e.g., providing sense of meaning), and (i) other psychological (e.g., emotional gratification). Views of compensation varied: not a factor (55%), added incentive (25%), main motivator, but in conjunction with altruism (15%), and primary motivator (5%). HVT participants thus often have both altruistic and financial motives, and related typologies emerged. These findings have critical implications for studies on HIV, other conditions, and research ethics.

description: Given $n$ independent random variables $X_1, X_2, ..., X_n$ and an integer $C$, we study the fundamental problem of computing the probability that the sum $X=X_1+X_2+...+X_n$ is at most $C$. We assume that each random variable $X_i$ is implicitly given by an oracle which, given an input value $k$, returns the probability $X_i\leq k$. We give the first deterministic fully polynomial-time approximation scheme (FPTAS) to estimate the probability up to a relative error of $1\pm ε$. Our algorithm is based on the idea developed for approximately counting knapsack solutions in [Gopalan et al. FOCS11].
