description: We give a general overview of the high-frequency regime in periodically driven systems and identify three distinct classes of driving protocols in which the infinite-frequency Floquet Hamiltonian is not equal to the time-averaged Hamiltonian. These classes cover systems, such as the Kapitza pendulum, the Harper-Hofstadter model of neutral atoms in a magnetic field, the Haldane Floquet Chern insulator and others. In all setups considered, we discuss both the infinite-frequency limit and the leading finite-frequency corrections to the Floquet Hamiltonian. We provide a short overview of Floquet theory focusing on the gauge structure associated with the choice of stroboscopic frame and the differences between stroboscopic and non-stroboscopic dynamics. In the latter case one has to work with dressed operators representing observables and a dressed density matrix. We also comment on the application of Floquet Theory to systems described by static Hamiltonians with well-separated energy scales and, in particular, discuss parallels between the inverse-frequency expansion and the Schrieffer-Wolff transformation extending the latter to driven systems.

description: In the commented work (PRL 109, 187005 (2012)), Rullier-Albenque et al. present measurements of transverse magnetoresistivity above the transition temperature Tc in clean LiFeAs. By analyzing their data, these authors conclude that the conductivity induced by fluctuations follows a two-dimensional (2D) behavior even close to Tc, in spite that for LiFeAs the transverse coherence length ($ξ_c$(0)=1.6 nm) is larger than the Fe-layers spacing (s=0.636 nm), which would rather suggest a three-dimensional (3D) behavior. This striking proposal would have deep implications in the theoretical understanding of the multiband structure of iron pnictides, but it also contrasts with the 3D behavior observed near Tc in the same compound and in other iron pnictides with even smaller $ξ_c$(0)/s ratios. Here we show that the proposal of Rullier et al. could be just an artifact associated to an inadequate subtraction of the normal-state contribution.

We classify all minimal parabolic subgroups of G for which the associated cuspidal integrals are convergent and discuss the possible definitions of cusp forms. Finally, we show that the closure of the direct sum of the discrete series of representations of G/H coincides with the space of cusp forms.

description: Dynamics of earthquake nucleation process is studied on the basis of the one-dimensional Burridge-Knopoff (BK) model obeying the rate- and state-dependent friction (RSF) law. We investigate the properties of the model at each stage of the nucleation process, including the quasi-static initial phase, the unstable acceleration phase and the high-speed rupture phase or a mainshock. Two kinds of nucleation lengths L_sc and L_c are identified and investigated. The nucleation length L_sc and the initial phase exist only for a weak frictional instability regime, while the nucleation length L_c and the acceleration phase exist for both weak and strong instability regimes. Both L_sc and L_c are found to be determined by the model parameters, the frictional weakening parameter and the elastic stiffness parameter, hardly dependent on the size of an ensuing mainshock. The sliding velocity is extremely slow in the initial phase up to L_sc, of order the pulling speed of the plate, while it reaches a detectable level at a certain stage of the acceleration phase. The continuum limits of the results are discussed. The continuum limit of the BK model lies in the weak frictional instability regime so that a mature homogeneous fault under the RSF law always accompanies the quasi-static nucleation process. Duration times of each stage of the nucleation process are examined. The relation to the elastic continuum model and implications to real seismicity are discussed.

description: In this paper, we establish the existence of optimal bounded memory strategy profiles in multi-player discounted sum games. We introduce a non-deterministic approach to compute optimal strategy profiles with bounded memory. Our approach can be used to obtain optimal rewards in a setting where a powerful player selects the strategies of all players for Nash and leader equilibria, where in leader equilibria the Nash condition is waived for the strategy of this powerful player. The resulting strategy profiles are optimal for this player among all strategy profiles that respect the given memory bound, and the related decision problem is NP-complete. We also provide simple examples, which show that having more memory will improve the optimal strategy profile, and that sufficient memory to obtain optimal strategy profiles cannot be inferred from the structure of the game.

description: The productive environment over time is called to face unexpected challenges and adapt to new circumstances, with the result that the concept of flexibility and its relationship with production parameters constantly stimulates the interest of businesses. The present paper examines the influence of industrial flexibility on various parameters of production systems in conditions of uncertainty and lack of knowledge. Methodologically, simple design representations of the basic functions of the production systems are used, such as in-line processing/storage, assembly/concentration and disassembly/distribution of by-products to facilitate the synthesis, modeling and simulation of realistic-sized systems. Digital twins and system simulation models with different levels of flexibility are presented with the help of the Fuzzy Logic toolbox of Matlab/Simulink software. Conditions of failures, resource use, organizational / business options for different operating scenarios are examined, sensitivity analysis of the parameters involved is performed and conclusions are drawn.

description: Excerpts from the report Introduction: Commercial urea is a synthetic nitrogen compound used to replace part of the protein in the ration for cattle, sheep, and other ruminants. A ruminant cannot utilize urea directly, but microorganisms in the rumen convert urea to protein which can be digested. These microorganisms also need carbohydrates to feed on. It is advantageous to use commercial urea because the combined cost of urea and the requisite carbohydrates is usually much less than the cost of oilseed meals or other common sources of equivalent protein. This report presents the results of a national survey on urea used by cattle and calves on feed. It provides answers to such questions as how much urea is being consumed by cattle on feed, in what forms it is being fed, what percentages of feedlots and cattle on feed are being supplied with it, what are the most common sources of supply, and what regional and size group differences may be present.

description: Abstract
This study aims to analyze the interrelationships between influence tactics, perceived organizational support (POS) and employee job performance in Malaysia. The current research varies from prior studies in that it connects two types of influence tactics, soft and hard, with two types of job performance, task performance and contextual performance, as well as the moderator POS. The data for the study was collected using a self-administered questionnaire. Seven hypothesized relationships were tested in this research with a sample of 200 employees who work in the banking industry in Malaysia. Smart PLS (version 3.2.8) was applied to assess the developed model based on path modelling followed by bootstrapping. The results revealed that (POS) significantly moderated influence tactics on employee job performance. The implications, limitations, and directions for future research are further discussed.

The aim of these lectures was to present some aspects of the dimer model to a geometrically minded audience. We spoke neither of braids nor of knots, but tried to show how several geometrical tools that we know and love (e.g. (co)homology, spin structures, real algebraic curves) can be applied to very natural problems in combinatorics and statistical physics. These lecture notes do not contain any new results, but give a (relatively original) account of the works of Kasteleyn, Cimasoni-Reshetikhin and Kenyon-Okounkov-Sheffield.

description: The North Celestial Pole Loop (NCPL) provides a unique laboratory for studying the early stages of star formation, in particular the condensation of the neutral interstellar medium (ISM). Understanding the physical properties that control the evolution of its contents is key to uncovering the origin of the NCPL. Archival data from the NCPL region of the GHIGLS 21 cm line survey (9'4) are used to map its multiphase content with ${\tt ROHSA}$, a Gaussian decomposition tool that includes spatial regularization. Column density and mass fraction maps of each phase were extracted along with their uncertainties. Archival data from the DHIGLS 21 cm (1') survey are used to further probe the multiphase content of the NCPL. We have identified four spatially (and dynamically) coherent components in the NCPL, one of which is a remarkably well-defined arch moving at about $14\ {\rm km s^{-1}}$ away from us that could be a relic of the large-scale organized dynamical process at the origin of the phase transition. The cold and lukewarm phases together dominate the mass content of the neutral gas along the loop. Using absorption measurements, we find that the cold phase exhibits slightly supersonic turbulence.

description: Due to the complexity of heterogeneous catalysts, identification of active sites and the ways for their experimental design are not inherently straightforward but important for tailored catalyst preparation. The present study reveals the active sites for efficient C–H bond activation in C1–C4 alkanes over ZrO2 free of any metals or metal oxides usually catalysing this reaction. Quantum chemical calculations suggest that two Zr cations located at an oxygen vacancy are responsible for the homolytic C–H bond dissociation. This pathway differs from that reported for other metal oxides used for alkane activation, where metal cation and neighbouring lattice oxygen form the active site. The concentration of anion vacancies in ZrO2 can be controlled through adjusting the crystallite size. Accordingly designed ZrO2 shows industrially relevant activity and durability in non-oxidative propane dehydrogenation and performs superior to state-of-the-art catalysts possessing Pt, CrOx, GaOx or VOx species.

description: The oscillation of the CMB photons into axions can cause CMB spectral distortion in the presence of large scale magnetic field. With the COBE limit on the $μ$ parameter and a homogeneous magnetic field with strength $B\lesssim 3.2$ nG at the horizon scale, an upper limit on the axion mass is found to be, $m_a\lesssim 4.8\times 10^{-5}$ eV for the KSVZ axion model. On the other hand, using the value of excluded axion mass $m_a\simeq 3.5\times 10^{-6}$ eV from the ADMX experiment together with the COBE bound on $μ$, is found $B\simeq 46$ nG for the KSVZ axion model and $B\simeq 130$ nG for DFSZ axion model, for a homogeneous magnetic field with coherence length at the present epoch $λ_B\simeq 1.3$ Mpc. Forecast on $B$ and $m_a$ for PIXIE/PRISM expected sensitivity on $μ$ are derived. If CMB $μ$ distortion would be detected by the future space missions PIXIE/PRISM and assuming that the strength of the large scale magnetic field is close to its canonical value, $B\simeq 1-3$ nG, axions in the mass range $2\, μ$eV - $3\, μ$eV would be potential candidates of CMB $μ$-distortion.

Characterization of random features of chaotic eigenfunctions in unperturbed basis

description: In this paper, we study random features manifested in components of energy eigenfunctions of quantum chaotic systems, given in the basis of unperturbed, integrable systems. Based on semiclassical analysis, particularly on Berry's conjecture, it is shown that the components in classically allowed regions can be regarded as Gaussian random numbers in certain sense, when appropriately rescaled with respect to the average shape of the eigenfunctions. This suggests that, when a perturbed system changes from integrable to chaotic, deviation of the distribution of rescaled components in classically allowed regions from the Gaussian distribution may be employed as a measure for the ``distance'' to quantum chaos. Numerical simulations performed in the LMG model and the Dicke model show that this deviation coincides with the deviation of the nearest-level-spacing distribution from the prediction of random-matrix theory. Similar numerical results are also obtained in two models without classical counterpart.

Entangled languages : intimacy, desire, and love in the multilingual Maghrebi novel

description: What does it mean to love in more than one language in a postcolonial, multilingual context? Entangled Languages considers this question through Maghrebi novels of the late twentieth and early twenty-first century, analyzing representations of multilingualism as they relate to love, intimacy, and desire. The linguistic situation of literature in the Maghreb since decolonization has often been discussed in terms of violence and trauma. I argue that this critical focus has overlooked desire, intimacy, and love as equally significant themes in representations of language. This project focuses on works by Moroccan, Tunisian, and Algerian authors to trace the ways in which Maghrebi novelists writing in French and Arabic have portrayed multilingualism through intimate metaphors. Using a scaffolding of close reading, historical analysis, affect and queer theory, and linguistic philosophy, I compare the representations of multilingualism in these novels across language, place, and time. The first chapter explores love and the personification of language in three seminal novels from the early 1980s: Abdelkebir Khatibi's Amour bilingue, Assia Djebar's L'amour, la fantasia, and Abdelwahab Meddeb's Phantasia. The second chapter investigates the different ways that two Algerian novelists writing in the 1990s, Ahlam Mosteghanemi and Nina Bouraoui, ascribe gender to Arabic in their work, and the relationship between the gendering of language and desire. Finally, the third chapter looks at the failures of intimacy within metaphoric guest/host relationships in two early-2000s narratives of immigration by Mahi Binebine and Habib Selmi. Entangled Languages demonstrates how writers have used intimacy, desire, and love to reimagine the “linguistic drama” of the Maghreb.

These statements hold for both with and without inhomogeneity. The proof can be generalized to other finite-dimensional quantum integrable models.

description: Autonomous systems no longer operate in isolation. In many applications, ranging from ride-hailing to on-demand delivery and surveillance, they carry out tasks in the presence of other autonomous systems and humans. For successful operations in these applications, autonomous systems need to reason about uncertainty to co-exist alongside other agents, understand motivations to cooperate with friends, and strategically manipulate information to compete against adversaries. In this dissertation, we present novel cooperation and competition capabilities for autonomous systems to accomplish tasks with theoretical performance guarantees in the presence of other agents. First, we focus on cooperation and develop algorithms for an autonomous agent to influence the behavior of another agent through sequential incentive offers. Second, we consider an autonomous agent operating in adversarial environments and develop algorithms for the agent to compete against adversaries by minimizing the predictability of its goal-directed behavior. Third, we develop an algorithm for an autonomous agent to deceive outside observers regarding its intentions while carrying out tasks in stochastic environments. For each of these capabilities, we model the agent behavior via Markov decision processes and present a comprehensive theoretical analysis that establishes conditions for the existence of optimal solutions and the complexity of computing those solutions. Furthermore, we contribute to the theory of Markov decision processes by presenting an analysis for a new formulation that combines total discounted cost criterion with a reachability constraint.

description: Carbonylation reactions of alkenes constitute the most important industrial processes in homogeneous catalysis. Despite the tremendous progress in this transformation, the development of advanced catalyst systems to improve their activity and widen the range of feedstocks continues to be essential for new practical applications. Herein a palladium catalyst based on 1,2-bis((tert-butyl(pyridin-2-yl)phosphanyl)methyl)benzene L3 (py t bpx) is rationally designed and synthesized. Application of this system allows a general alkoxycarbonylation of sterically hindered and demanding olefins including all kinds of tetra-, tri-and 1,1-disubstituted alkenes as well as natural products and pharmaceuticals to the desired esters in excellent yield. Industrially relevant bulk ethylene is functionalized with high activity (TON: >1,425,000; TOF: 44,000 h-1 for initial 18 h) and selectivity (>99%). Given its generality and efficiency, we expect this catalytic system to immediately impact both the chemical industry and research laboratories by providing a practical synthetic tool for the transformation of nearly any alkene into a versatile ester product.

description: A century after the advent of Quantum Mechanics and General Relativity, both theories enjoy incredible empirical success, constituting the cornerstones of modern physics. Yet, paradoxically, they suffer from deep-rooted, so-far intractable, conflicts. Motivations for violations of the notion of relativistic locality include the Bell's inequalities for hidden variable theories, the cosmological horizon problem, and Lorentz-violating approaches to quantum geometrodynamics, such as Horava-Lifshitz gravity. Here, we explore a recent proposal for a "real ensemble" non-local description of quantum mechanics, in which "particles" can copy each others' observable values AND phases, independent of their spatial separation. We first specify the exact theory, ensuring that it is consistent and has (ordinary) quantum mechanics as a fixed point, where all particles with the same values for a given observable have the same phases. We then study the stability of this fixed point numerically, and analytically, for simple models. We provide evidence that most systems (in our study) are locally stable to small deviations from quantum mechanics, and furthermore, the phase variance per value of the observable, as well as systematic deviations from quantum mechanics, decay as $\sim$ (Energy$\times$Time)$^{-2n}$, where $n \geq 1$. Interestingly, this convergence is controlled by the absolute value of energy (and not energy difference), suggesting a possible connection to gravitational physics. Finally, we discuss different issues related to this theory, as well as potential novel applications for the spectrum of primordial cosmological perturbations and the cosmological constant problem.

description: The production of primary benzylic and aliphatic amines, which represent essential feedstocks and key intermediates for valuable chemicals, life science molecules and materials, is of central importance. Here, we report the synthesis of this class of amines starting from carbonyl compounds and ammonia by Ru-catalyzed reductive amination using H2. Key to success for this synthesis is the use of a simple RuCl2(PPh3)3 catalyst that empowers the synthesis of >90 various linear and branched benzylic, heterocyclic, and aliphatic amines under industrially viable and scalable conditions. Applying this catalyst, −NH2 moiety has been introduced in functionalized and structurally diverse compounds, steroid derivatives and pharmaceuticals. Noteworthy, the synthetic utility of this Ru-catalyzed amination protocol has been demonstrated by upscaling the reactions up to 10 gram-scale syntheses. Furthermore, in situ NMR studies were performed for the identification of active catalytic species. Based on these studies a mechanism for Ru-catalyzed reductive amination is proposed.

description: Let G be a split connected reductive group over a local non-archimedean field. We classify all irreducible complex G-representations in the principal series, irrespective of the (dis)connectedness of the centre of G. This leads to a local Langlands correspondence for principal series representations, which satisfies all expected properties. We also prove that the ABPS conjecture about the geometric structure of Bernstein components is valid throughout the principal series of G.
description: This is a revised and abridged version of part 3 of "Geometric structure and the local Langlands correspondence" (arXiv:1211.0180). In v2 some proofs involving temperedness and square-integrability were worked out in more detail (pages 30-31 and 51-53)
In a feminist state? : sexual violence and gender equality in Sweden

description: According to the World Economic Forum, Sweden ranks as one of the most women-friendly countries in the world and has been called a “gender equal utopia” (Fiig 2009: 199). Yet at the same time, Sweden has one of the highest reported rates of sexual violence in the world. What explains the paradox of Sweden’s high reported rate of rape and high level of gender equality? By engaging in multi-method fieldwork inspired by Dorothy Smith’s institutional ethnography, I illuminate the ways in which sexual violence is framed and addressed from a socio-legal perspective. My findings suggest that the high reported rate of sexual violence in Sweden is not necessarily a paradox, but rather a reflection of a commitment to gender equality: Swedish state institutions incentivize reporting of sexual violence, encouraging victim-survivors to disclose and seek help. In this dissertation, I look to three state institutions to illuminate how the Swedish state incentivizes reporting. First, I write about the political sphere, where a 2018 legal reform was hotly contested but ended with a “feminist victory.” Second, I examine the criminal justice system, where victim-centered policies and practices have been implemented to improve the experience of victim-survivors who report. Finally, I turn to the welfare state, including the healthcare system and the education system, where government-funded programs address sexual violence treatment and prevention. Through a transformation of these state institutions, Sweden provides accessible services and possibilities for justice. Thus, I argue that a high reported rate of sexual violence does not necessarily reflect the high occurrence of rape and sexual assault, but in the case of Sweden, may reflect the successful work of feminist activism and a state commitment to gender equality through institutionalized support for disclosure and reporting.

description: We have determined the temperature dependence of the solvation behavior of a large collection of important light gases in imidazolium-based ionic liquids with the help of extensive molecular dynamics simulations. The motivation of our study is to unravel common features of the temperature dependent solvation under well controlled conditions, and to provide a guidance for cases, where experimental data from different sources disagree significantly. The solubility of molecular hydrogen, oxygen, nitrogen, methane, krypton, argon, neon and carbon dioxide in the imidazolium based ionic liquids of type 1-n-alkyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([Cnmim][NTf2]) with varying alkyl side chain lengths n = 2, 4, 6, 8 is computed for a temperature range between 300 K and 500 K at 1 bar. By applying Widom's particle insertion technique and Bennet's overlapping distribution method, we are able to determine the temperature dependent solvation free energies of those selected light gases in simulated imidazolium based ionic liquids with high statistical accuracy. Our simulations demonstrate that the magnitude of the solvation free energy of a gas molecule at a chosen reference temperature and that of its temperature-derivatives are intimately related to one another. We conclude that this "universal" behavior is rooted in a solvation entropy-enthalpy compensation effect, which seems to be a defining feature of the solvation of small molecules in ionic liquids. The observations lead to simple analytical relations, determining the temperature dependence of the solubility data based on the absolute solubility at a certain reference temperature. By comparing our results with available experimental data from many sources, we can show that our approach is particularly helpful for providing reliable estimates for the solvation behavior of very light gases, such as hydrogen, where conflicting experimental data exist.

description: We consider the conventional Laplace transform of $f(x)$, denoted by $\mathcal{L}[f(x); p]~\equiv~F(p)=\int_{0}^{\infty} e^{-p x} f(x) dx$ with ${\rm \mathfrak{Re}}(p) > 0$. For $0 < α< 1$ we furnish the closed form expressions for the inverse Laplace transforms $\mathcal{L}^{-1}[F(p^α); x]$ and $\mathcal{L}^{-1}[p^{α-1}F(p^α); x]$. In both cases they involve definite integration with kernels which are appropriately rescaled one-sided Lévy stable probability distribution functions $g_α(x)$, $0 < α< 1$, $x > 0$. Since $g_α(x)$ are exactly and explicitly known for rational $α$, \textit{i.e.} for $α= l/k$ with $l, k=1, 2, \ldots$, $l < k$, our results extend the known and tabulated case of $α= 1/2$ to any rational $0 < α< 1$. We examine the integral kernels of this procedure as well as the resulting two kinds of Lévy integral transformations.

description: Há uma escassez na literatura de estudos que investiguem os efeitos do tempo de retenção na estabilidade dos arcos maxilares, e ainda não há uma concordância entre os protocolos de diferentes métodos de contenção e por quanto tempo a retenção precisa ser usada. Desse modo, a justificativa deste estudo se dá pela carência na literatura acessível de trabalhos que relatem os efeitos do tempo de retenção na estabilidade dos arcos maxilares e prevenção de recidivas, que, embora tenham se tornado crescentes nos últimos anos, ainda não são suficientes para uma revisão sistemática, e também por esta ser tanto uma pergunta de relevância clínica para os ortodontistas que desejam fazer uma indicação de forma mais precisa, com embasamento científico, do tempo que os pacientes devem permanecer com as contenções fixadas nos elementos dentários anteroinferiores, quanto para os pacientes que sempre questionam se as suas contenções já podem ser removidas. Portanto, o objetivo desta revisão de escopo será identificar na literatura as lacunas de conhecimento sobre qual a indicação de tempo para a permanência das contenções ortodônticas fixas mandibulares, de forma a produzir evidências e tendências a partir dos dados gerados e favorecer estudos futuros.

description: The geometric approach [1312.1262] to iterated variations of local functionals -- e.g., of the (master-)action functional -- resulted in an extension of the deformation quantisation technique to the set-up of Poisson models of field theory [IHES/M/15/13]. It also allowed of a rigorous proof ([1312.1262],[1210.0726]) for the main inter-relations between the Batalin-Vilkovisky (BV) Laplacian $Δ$ and variational Schouten bracket. The ad hoc use of these relations had been a known analytic difficulty in the BV-formalism for quantisation of gauge systems; now achieved, the proof does actually not require the assumption of graded-commutativity [1210.0726]. Explained in our previous work, geometry's self-regularisation is rendered by Gel'fand's calculus of singular linear integral operators supported on the diagonal. We now illustrate that analytic technique by inspecting the validity mechanism [1312.4140] for the graded Jacobi identity which the variational Schouten bracket does satisfy (whence $Δ^2=0$, i.e., the BV-Laplacian is a differential acting in the algebra of local functionals). By using one tuple of three variational multi-vectors twice, we contrast the new logic of iterated variations -- when the right-hand side of Jacobi's identity vanishes altogether -- with the old method: interlacing its steps and stops, it could produce some non-zero representative of the trivial class in the top-degree horizontal cohomology. But we then show at once by an elementary counterexample why, in the frames of the old approach that did not rely on Gel'fand's calculus, the BV-Laplacian failed to be a graded derivation of the variational Schouten bracket.
