description: Redundancy matrices provide insights into the load carrying behavior of statically indeterminate structures. This information can be employed for the design and analysis of structures with regard to certain objectives, for example reliability, robustness, or adaptability. In this context, the structure is often iteratively examined with the help of slight adjustments. However, this procedure generally requires a high computational effort for the recalculation of the redundancy matrix due to the necessity of costly matrix operations. This paper addresses this problem by providing generic algebraic formulations for efficiently updating the redundancy matrix (and related matrices). The formulations include various modifications like adding, removing, and exchanging elements and are applicable to truss and frame structures. With several examples, we demonstrate the interaction between the formulas and their mechanical interpretation. Finally, a performance test for a scaleable structure is presented.

description: We report a high-resolution resonant inelastic soft x-ray scattering study of the quantum magnetic spin-chain materials Li2CuO2 and CuGeO3. By tuning the incoming photon energy to the oxygen K-edge, a strong excitation around 3.5 eV energy loss is clearly resolved for both materials. Comparing the experimental data to many-body calculations, we identify this excitation as a Zhang-Rice singlet exciton on neighboring CuO4-plaquettes. We demonstrate that the strong temperature dependence of the inelastic scattering related to this high-energy exciton enables to probe short-range spin correlations on the 1 meV scale with outstanding sensitivity.

description: Here, I study the problem of classification of non-split supermanifolds having as retract the split supermanifold $(M,Ω)$, where $Ω$ is the sheaf of holomorphic forms on a given complex manifold $M$ of dimension $> 1$. I propose a general construction associating with any $d$-closed $(1,1)$-form $ω$ on $M$ a supermanifold with retract $(M,Ω)$ which is non-split whenever the Dolbeault class of $ω$ is non-zero. In particular, this gives a non-empty family of non-split supermanifolds for any flag manifold $M\ne \mathbb{CP}^1$. In the case where $M$ is an irreducible compact Hermitian symmetric space, I get a complete classification of non-split supermanifolds with retract $(M,Ω)$. For each of these supermanifolds, the 0- and 1-cohomology with values in the tangent sheaf are calculated. As an example, I study the $Π$-symmetric super-Grassmannians introduced by Yu. Manin.

description: Статья посвящена творчеству курских писателей 1900—1910-х годов. На основе анализа художественных текстов (очерк, фельетон, рассказ, новелла) осмысляется своеобразие малых жанров, специфика которых определялась российскими общелитературными процессами и в то же время имела свои особенности. Обращение к изучению этого материала, на сегодняшний день малодоступного современному читателю, собираемого и восстанавливаемого буквально по крупицам, имеет важное значение, так как позволяет заполнить лакуны одной из составляющей регистра курского литературного локуса и делает представление о нём более объёмным. И хотя не все произведения литераторов отличались высоким художественным уровнем, можно утверждать, что их проза вошла в число тех творений, успех которых, пусть и негромкий, был обусловлен точным ответом их авторов на духовные и эстетические запросы определенных социокультурных слоев читательской аудитории и желанием наиболее объективно воспроизвести реальную.

description: In this paper we constructed a semi-realistic cosmological model in a dynamic domain wall framework. Our universe is considered to be a (3+1) dimensional dynamic domain wall in a higher dimensional Einstein-Maxwell-Born-Infeld background. One of our interesting outcomes from the effective Hubble equation for the domain wall dynamics is that it contains an additional component of "dark matter" which is induced from the charge of the bulk Born-Infeld gauge field. In this background spacetime we have studied the cosmological dynamics of the domain wall. In addition to the Born-Infield gauge field if we consider additional pure gauge field, a non-singular bounce happens at the early stage with a smooth transition between contracting and expanding phase.

description: Языковая личность, которая была одновременно формируемой и формирующей, все больше становится формирующей по отношению к литературе. Современная художественная литература, скорее, отражает языковую личность, чем формирует ее. Однако для иностранных учащихся литература остается важным условием постижения русского языка и формирования их вторичной языковой личности. Перед преподавателями русского языка как иностранного неизбежно встает проблема выбора художественного текста: классический или современный. Иностранные студенты-нефилологи обычно предпочитают современные тексты, и многое говорит в их пользу, однако практика показывает, что современные произведения нередко оказываются не менее трудны для адекватного понимания, чем классика, поэтому очевидна необходимость реального комментария, который снимает экстралингвистические трудности. Ценность реального комментария заключается также в том, что после чтения текста он побуждает к диалогу в более широком контексте: социокультурном, историческом, идеологическом.

Using a sample generated by the AMPT model with string melting, we demonstrate that the azimuthal amplitude of the suggested distribution characterizes the anisotropic radial flow, and coincides with the parameter of anisotropic radial rapidity extracted from a generalized blast-wave parametrization.

description: Автор рассказывает о личном опыте работы в рамках авторского курса «Воплощение образов русской литературы в кинематографе», который читает обучающимся в магистратуре студентам по профилю «Литература в системе гуманитарного образования». В связи с тем, что молодежь теряет мотивацию к чтению, предлагаются разные способы усовершенствовать методику преподавания литературы, в том числе через использование экранизаций литературных произведений. В том случае, когда экранизация сделана отечественными кинематографистами по мотивам литературного произведения или в формате его адаптации, предлагается сделать первичным не чтение текста, а просмотр его экранизации. Сопоставление произведений кинематографа, созданных по мотивам русской литературной классики, и произведений литературы развивает умение выделить удачную экранизацию. Это умение, как и знание типов экранизации, магистры могут использовать в дальнейшей педагогической деятельности.

description: Traditionally, Epistemic Logic represents epistemic scenarios using a single model. This, however, covers only complete descriptions that specify truth values of all assertions. Indeed, many -- and perhaps most -- epistemic descriptions are not complete. Syntactic Epistemic Logic, SEL, suggests viewing an epistemic situation as a set of syntactic conditions rather than as a model. This allows us to naturally capture incomplete descriptions; we discuss a case study in which our proposal is successful. In Epistemic Game Theory, this closes the conceptual and technical gap, identified by R. Aumann, between the syntactic character of game-descriptions and semantic representations of games.

description: According to the Organisation for Economic Co-operation and Development (OECD), environmental literacy is the intended outcome of environmental education. Following this postulate, this study aims to investigate the presence of a spatial correlation between the OECD environmental literacy index and the levels of empirical knowledge production in environmental education. In particular, a frequency count of country-specific citations appearing in two leading environmental education journals was used as an indicator of empirical knowledge production. Data analysis showed that countries with higher levels of empirical knowledge production in environmental education (higher frequency of citations in environmental education literature) achieve better outcomes in international environmental literacy tests. Future studies can build on this work to explore the relationship between the production of environmental education knowledge and environmental literacy.

description: We study conformal field theories with finite group symmetries with spontaneous symmetry breaking (SSB) phases that persist at all temperatures. We work with two $λϕ^4$ theories coupled through their mass terms. The two $λϕ^4$ theories are chosen to preserve either the cubic symmetry group or the tetrahedral symmetry group. A one-loop calculation in the $4-ε$ expansion shows that there exist infinitely many fixed points that can host an all temperature SSB phase. An analysis of the renormalization group (RG) stability matrix of these fixed points, reveals that their spectrum contains at least three relevant operators. In other words, these fixed points are tetracritical points.

description: We study the non-Markovianity of the dynamics of open quantum systems focusing on the cases of independent and common environmental interactions. We investigate the degree of non-Markovianity quantified by two distinct measures proposed by Luo, Fu and Song (LFS) and Breuer, Laine and Pillo (BLP). We show that the amount of non-Markovianity, for a single and a pair of qubits, depends on the quantum process, the proposed measure and whether the environmental interaction is collective or independent. In particular, we demonstrate that while the degree of non-Markovianity generally increases with the number of the qubits in the system for independent environments, the same behavior is not always observed for common environments. In the latter case, our analysis suggests that the amount of non-Markovianity could increase or decrease depending on the properties of the considered quantum process.

description: Writing, a critical pedagogical tool, cultivates student learning and fosters deeper understanding of the material. When frequent, low -stakes (informal) writing activities help students write more freely, engage with the material and thus become active learners. Looking at students who are at opposite ends of a community college spectrum, this article compares and contrasts students’ writing skills using low-stakes assignments, including peer-reviewing of each other’s work, in a capstone course and in a First-Year Seminar in terms of organization, clarity in communication and content analysis. The data generated from this study stem from an interdisciplinary collaboration among three instructors from Humanities, Mathematics and Natural Sciences, with the goal of creating a network between students in First-Year Seminars and students in the capstone course. Research methods in this context included assigning common readings to students in different classes on the theme of Women in STEM. It also included a peer review component: students reviewed each other’s assignments and instructors visited each other’s class to lead a discussion on the paucity of women in the fields of sciences or as Nobel Prize winner, with the additional aim of improving women’s interest in STEM courses.
Ferromagnetic Kondo effect in a triple quantum dot system

description: We propose that a simple device of three laterally-coupled quantum dots, the central one contacted by metal leads, can realize the ferromagnetic Kondo model, which is characterized by interesting properties like a non-analytic inverted zero-bias anomaly and an extreme sensitivity to a magnetic field. Furthermore, by tuning the gate voltages of the lateral dots, this device may allow to study the transition from ferromagnetic to antiferromagnetic Kondo effect, a simple case of a Berezinskii-Kosterlitz-Thouless transition. We model the device by three coupled Anderson impurities that we study by numerical renormalization group. We calculate the single-particle spectral function of the central dot, which at zero frequency is proportional to the zero-bias conductance, across the transition, both in the absence and in the presence of a magnetic field.

description: We study linear perturbations around time dependent spherically symmetric solutions in the Lambda_3 massive gravity theory, which self-accelerate in the vacuum. We find that the dynamics of the scalar perturbations depend on the coordinate choice for the background solutions. For particular choices of coordinates there is a symmetry enhancement, leaving no propagating scalar degrees of freedom at linear order in perturbations. In contrast, any other coordinate choice propagates a single scalar mode. We find that the Hamiltonian of this scalar mode is unbounded from below for all self-accelerating solutions, signalling an instability.

description: The present work reports on the dynamical measures of order, disorder and complexity for the interacting bosons in optical lattice. We report results both for the relaxed state as well as quench dynamics. Our key observations are: (1) Lattice depth can be taken as order-disorder parameter. (2) The superfluid to Mott insulator transition can be treated as `order-disorder' transition. Our main motivation is to find how the system organize by itself during quench and how it optimizes the complexity. We find dynamical measures of order and disorder are more sensitive tool than entropy measures. We specifically calculate the time scale of entry and exit of different phases during time evolution. Initially the system exhibits collapse revival trend, however gradually looses its ability to turn back to superfluid phase and finally Settle to Mott insulator phase.

To have the infalling boundary condition to make the hydrodynamic analysis possible, we treat the infrared energy scale factor in our metric as a temperature-depending parameter. Then, by carrying out the hydrodynamic analysis, we compute the transport coefficients, the diffusion constant, and the shear viscosity, through the linear response theory.

Remark on Calabi-Yau vacua of the string theory and the cosmological constant problem

Year: 2013
Subjects: subject: High Energy Physics - Theory (hep-th)

description: We propose, based on the viewpoint that our three-dimensional space is a stack of BPS D3-branes located at the conifold singularity of the Calabi-Yau three-fold, a new mechanism to address the cosmological constant problem in the framework of the conventional compactifications where the $n$-form fluxes including NS-NS three-form are all turned off. In this mechanism the four-dimensional cosmological constant $λ$ appears as two types, NS-NS type and R-R type, of vacuum energies on the brane plus supersymmetry breaking term, which constitute a brane action density ${\hat I}_{\rm brane}$, and sum of these three terms of ${\hat I}_{\rm brane}$ are forced to vanish by field equations so that $λ$ adjusts itself to zero as a result. Also in this mechanism the $d=4$ supersymmetry is broken in the brane region, while still maintaining $λ=0$. The supersymmetry breaking occurs as a result of the gauge symmetry breaking of the R-R four-form arising at the quantum level. We generalize the above mechanism to the case of the flux compactifications where the fluxes are all turned on to stabilize the moduli. In the generalized theory $λ$ appears as ${\hat I}_{\rm brane}$ plus the scalar potential ${\mathcal V}_{\rm scalar}$ for the moduli, in contrast to the case of the ordinary flux compactifications where $λ$ is simply given by ${\mathcal V}_{\rm scalar}$. Also in this theory any nonzero ${\mathcal V}_{\rm scalar}$ arising from perturbative or nonperturbative corrections is gauged away by the gauge arbitrariness of ${\hat I}_{\rm brane}$ and the condition $λ=0$. So $λ$ is again expressed only as a brane action density as before, or it simply vanishes by the cancelation between ${\hat I}_{\rm brane}$ and ${\mathcal V}_{\rm scalar}$.

description: An iterated uniform finite-state transducer (IUFST) runs the same length-preserving transduction, starting with a sweep on the input string and then iteratively sweeping on the output of the previous sweep. The IUFST accepts the input string by halting in an accepting state at the end of a sweep. We consider both the deterministic (IUFST) and nondeterministic (NIUFST) version of this device. We show that constant sweep bounded IUFSTs and NIUFSTs accept all and only regular languages. We study the state complexity of removing nondeterminism as well as sweeps on constant sweep bounded NIUFSTs, the descriptional power of constant sweep bounded IUFSTs and NIUFSTs with respect to classical models of finite-state automata, and the computational complexity of several decidability questions. Then, we focus on non-constant sweep bounded devices, proving the existence of a proper infinite nonregular language hierarchy depending on the sweep complexity both in the deterministic and nondeterministic case. Though NIUFSTss are "one-way" devices we show that they characterize the class of context-sensitive languages, that is, the complexity class DSpace(lin). Finally, we show that the nondeterministic devices are more powerful than their deterministic variant for a sublinear number of sweeps that is at least logarithmic.

description: Motivated by experience with students’ psychological barriers to learning statistics, we modified and extended the Statistical Anxiety Rating Scale (STARS) to develop a contemporary and valid (face, content, criterion and construct) Danish measure of attitudes and relationship towards statistics for use with higher education students taking statistics within another discipline. Two subscales were excluded because of lack of conceptual unidimensionality or derogatory content, and single items were modified for face and content validity enhancement in the remaining subscales. Following a pilot study and main study, the resulting 26-item Danish instrument (HFS-R) consists of four subscales; Test and Class Anxiety (TCA), Interpretation Anxiety (IA), Fear of Asking for Help (FAH), Worth of Statistics (WS). Each scale was analyzed using Rasch and graphical loglinear Rasch models. The FAH subscale fit the Rasch model, while the TCA, IA and WS subscales each fit GLLRMs each with evidence of DIF. One TCA item functioned differentially relative to age, one WS item relative to statistics course (first or second), and two IA items relative to statistics course and academic discipline (sociology, public health). The IA and TCA subscales were well targeted to the study population, while targeting of FAH and WS was poorer. Unidimensionality across the three anxiety subscales (FAH, TCA & IA) was tested and clearly rejected. The HFS-R was found to be of sufficient psychometric quality to warrant its use in higher education research and teaching. We recommend that unidimensionality should be formally tested before using composite scores across anxiety subscales in the original STARS.

description: We consider the effects of metastable charged sparticles on Big-Bang Nucleosynthesis (BBN), including bound-state reaction rates and chemical effects. We make a new analysis of the bound states of negatively-charged massive particles with the light nuclei most prominent in BBN, and present a new code to track their abundances, paying particular attention to that of Li7. Assuming, as an example, that the gravitino is the lightest supersymmetric particle (LSP), and that the lighter stau slepton, stau_1, is the metastable next-to-lightest sparticle within the constrained minimal supersymmetric extension of the Standard Model (CMSSM), we analyze the possible effects on the standard BBN abundances of stau_1 bound states and decays for representative values of the gravitino mass. Taking into account the constraint on the CMSSM parameter space imposed by the discovery of the Higgs boson at the LHC, we delineate regions in which the fit to the measured light-element abundances is as good as in standard BBN. We also identify regions of the CMSSM parameter space in which the bound state properties, chemistry and decays of metastable charged sparticles can solve the cosmological Li7 problem.

Moreover, V is Killing. Finally, we prove that if M is a 3-dimensional compact contact metric manifold such that Qφ=φQ endowed with a quasi Yamabe soliton, then either M is flat or soliton is trivial.

description: A collective-variable approach for the study of non-linear dynamics of magnetic textures in planar nano-magnets is proposed. The variables are just arbitrary parameters (complex or real) in the specified analytical function of a complex variable, describing the texture in motion. Starting with such a function, a formal procedure is outlined, allowing a (non-linear) system of differential equations of motion to be obtained for the variables. The resulting equations are equivalent to Landau-Lifshitz-Gilbert dynamics as far as the definition of collective variables allows it. Apart from the collective-variable specification, the procedure does not involve any additional assumptions (such as translational invariance or steady-state motion). As an example, the equations of weakly non-linear motion of a magnetic vortex are derived and solved analytically. A simple formula for the dependence of the vortex precession frequency on its amplitude is derived. The results are verified against special cases from the literature and agree quantitatively with experiments and simulations.

description: Digital competence and digital literacy are concepts that are increasingly used in public discourse. However, how the concepts are used and how they are defined remains unclear. This paper presents a systematic review of research where these concepts are used in higher education research. The aim is to establish an understanding of referencing strategy to digital literacy and digital competence over time, disciplines, countries, methods and level of analysis. Three databases were used in the systematic literature review: Web of Science, Scopus and Education Resources Information Centre. We delimited the search to title, abstract and keywords in the databases. Inclusion criteria were peer-reviewed publications written in English. Initially 107 publications between 1997 and 2017 were found, with 28 addressing digital competence and 79 digital literacy. Our review demonstrates that there is a range of definitions used in higher education research. They vary depending on if the concepts are defined by policy, research or both and whether they focus on technical skills or social practices. This review indicates directions for further research in higher education i) do more research based on critical perspectives to avoid commonsensical use of the concepts, ii) take the development of definitions of these concepts seriously iii) avoid cross-referencing incompatibilities and finally iv) engage in critical investigations regarding the legitimacy of policy over research in the domain of higher education research.

description: We propose a model-independent and general framework to study the LHC phenomenology of top partners, i.e. Vector-Like quarks including particles with different electro-magnetic charge. We consider Vector-Like quarks embedded in general representations of the weak SU(2)L, coupling to all Standard Model quarks via Yukawa mixing focusing on the case of a single multiplet. We show that, with very minimal and quite general assumptions, top partners may be studied in terms of few parameters in an effective Lagrangian description with a clear and simple connection with experimental observables. We also demonstrate that the parametrisation can be applied as well to cases with many Vector-like multiplets, thus covering most realistic models of New Physics. We perform a numerical study to understand the conclusions which can be drawn within such a description and the expected potential for discovery or exclusion at the LHC. Our main results are a clear connection between branching ratios and single production channels, and the identification of novel interesting channels to be studied at the LHC.

description: This study sought to examine the extent of contribution of school feeding programmes towards the achievement of the Free Compulsory Universal Basic Education (FCUBE) policy in countries. Based on a purposive sampling of a deprived rural community in northern Ghana, the study utilised the concurrent mixed method design relying mainly on documentary analysis, questionnaires and interviews as data sources. A sample of 377 participants made up of teachers and parents were drawn for the research. Data were analysed using descriptive statistics and qualitative content analysis. The main finding of the study was that the programme had a positive influence on school enrolment and retention which are key indicators of the achievement of the FCUBE policy. Recommendations proffered pointed to the need to extend the SFP to other deprived areas, and to give the programme in Ghana a constitutional backing among others.

description: We study the superconducting properties of the non-centrosymmetric compound LaNiC$_2$ by measuring the London penetration depth $Δλ(T)$, the specific heat $C(T,B)$ and the electrical resistivity $ρ(T,B)$. Both $Δλ(T)$ and the electronic specific heat $C_e(T)$ exhibit exponential behavior at low temperatures and can be described in terms of a phenomenological two-gap BCS model. The residual Sommerfeld coefficient in the superconducting state, $γ_0(B)$, shows a fast increase at low fields and then an eventual saturation with increasing magnetic field. A pronounced upturn curvature is observed in the upper critical field $B_{c2}(T)$ near $T_{c}$. All the experimental observations support the existence of two-gap superconductivity in LaNiC$_2$.

description: We discuss the general mechanism leading to long-range rapidity and angular correlations produced in high energy collisions (the "ridge"). This effect naturally appears in the high energy QCD and is strongly sensitive to physics of the gluon saturation. We comment on various recent practical realizations of the main idea, paying special attention to $N_c$ counting and stress the relevance of Pomeron loops.

description: Рассматриваются связи литературоведческой науки и методики обучения литературе. В центре внимания — работы литературоведов, посвященные проблемам изучения литературе в школе. Методология литературного образования в разные эпохи формируется в них. Литературоведы с научных позиций определяют статус предмета, формулируют принципы литературного образования, предлагают пути выхода из кризиса, вариативные и альтернативные концепции курса литературы в школе. В разных социокультурных ситуациях литературоведами актуализируются проблемы «живого чтения», текстуального освоения литературы в школе, его научных основ, доказывается значимость духовного воспитания читателя-школьника, что являет национальную методическую традицию.
Structure and Power: an emerging landscape

description: In this paper, we give an overview of some recent work on applying tools from category theory in finite model theory, descriptive complexity, constraint satisfaction, and combinatorics. The motivations for this work come from Computer Science, but there may also be something of interest for model theorists and other logicians. The basic setting involves studying the category of relational structures via a resource-indexed family of adjunctions with some process category - which unfolds relational structures into treelike forms, allowing natural resource parameters to be assigned to these unfoldings. One basic instance of this scheme allows us to recover, in a purely structural, syntax-free way: the Ehrenfeucht-Fraisse~game; the quantifier rank fragments of first-order logic; the equivalences on structures induced by (i) the quantifier rank fragments, (ii) the restriction of this fragment to the existential positive part, and (iii) the extension with counting quantifiers; and the combinatorial parameter of tree-depth (Nesetril and Ossona de Mendez). Another instance recovers the k-pebble game, the finite-variable fragments, the corresponding equivalences, and the combinatorial parameter of treewidth. Other instances cover modal, guarded and hybrid fragments, generalized quantifiers, and a wide range of combinatorial parameters. This whole scheme has been axiomatized in a very general setting, of arboreal categories and arboreal covers. Beyond this basic level, a landscape is beginning to emerge, in which structural features of the resource categories, adjunctions and comonads are reflected in degrees of logical and computational tractability of the corresponding languages. Examples include semantic characterisation and preservation theorems, and Lovasz-type results on counting homomorphisms.

description: Выводы и наблюдения, представляемые в статье, базируются на практике преподавания литературы вузовским преподавателем в старших классах современных школ Великого Новгорода. Попытки учителя превратить уроки литературы в классическую «школу литературоведческого исследования текста» встречаются с сопротивлением современных старшеклассников, не желающих «углубленно» изучать литературу только потому, что профиль класса не предполагает «усиленного» внимания к гуманитарным дисциплинам. О попытках преодоления подобного прагматичного подхода к школьным дисциплинам и особенно к литературе как к предмету, от которого нет никакой «прямой пользы», и пойдет речь в настоящей статье.
