description: Local memory - the ability to extract information from a subsystem about its initial state - is a central feature of many-body localization. We introduce, investigate, and compare several information-theoretic quantifications of memory and discover a hierarchical relationship among them. We also find that while the Holevo quantity is the most complete quantifier of memory, vastly outperforming the imbalance, its decohered counterpart is significantly better at capturing the critical properties of the many-body localization transition at small system sizes. This motivates our suggestion that one can emulate the thermodynamic limit by artifically decohering otherwise quantum quantities. Applying this method to the von Neumann entropy results in critical exponents consistent with analytic predictions, a feature missing from similar small finite-size system treatments. In addition, the decohering process makes experiments significantly simpler by avoiding quantum state tomography.

description: Given any finite direction set $Ω$ of cardinality $N$ in Euclidean space, we consider the maximal directional Hilbert transform $H_Ω$ associated to this direction set. Our main result provides an essentially sharp uniform bound, depending only on $N$, for the $L^2$ operator norm of $H_Ω$ in dimensions 3 and higher. The main ingredients of the proof consist of polynomial partitioning tools from incidence geometry and an almost-orthogonality principle for $H_Ω$. The latter principle can also be used to analyze special direction sets $Ω$, and derive sharp $L^2$ estimates for the corresponding operator $H_Ω$ that are typically stronger than the uniform $L^2$ bound mentioned above. A number of such examples are discussed.

description: Taking advantage of the advances in generative deep learning, particularly normalizing flow, a framework, called Boltzmann Generator, has recently been proposed for the purpose of generating equilibrium atomic configurations from the canonical ensemble and determining the associated free energy. In this work, we revisit Boltzmann Generator to motivate the construction of the loss function from the statistical mechanical point of view, and to cast the training of the neural networks in a purely unsupervised manner that requires no samples of the atomic configurations from the equilibrium ensemble. We further show that the normalizing flow framework furnishes a reference thermodynamic system, very close to the real thermodynamic system under consideration, that is suitable for the well-established free energy perturbation methods to determine accurate free energy of solids. We then apply the normalizing flow to two problems: temperature-dependent Gibbs free energy of perfect crystal and formation free energy of monovacancy defect in a model system of diamond cubic Si. The results obtained from the normalizing flow are shown to be in good agreement with that obtained from independent well-established free energy methods.

Symplectic fillings of asymptotically dynamically convex manifolds II--$k$-dilations

Publisher: name: arXiv
Year: 2019
Subjects: subject: Symplectic Geometry (math.SG)
subject: FOS: Mathematics

description: We introduce the concept of $k$-(semi)-dilation for Liouville domains, which is a generalization of symplectic dilation defined by Seidel-Solomon. We prove that the existence of $k$-(semi)-dilation is a property independent of fillings for asymptotically dynamically convex (ADC) manifolds. We construct examples with $k$-dilations, but not $k-1$-dilations for all $k\ge 0$. We extract invariants taking value in $\mathbb{N} \cup \{\infty\}$ for Liouville domains and ADC contact manifolds, which are called the order of (semi)-dilation. The order of (semi)-dilation serves as embedding and cobordism obstructions. We determine the order of (semi)-dilation for many Brieskorn varieties and use them to study cobordisms between Brieskorn manifolds.

description: Antennas for wireless body area networks (WBAN) need to be modeled with adapted methods because the coupling with the body tissue does not allow for a clear separation between antenna and channel. Especially for dynamically varying on-body channels due to changing body poses, e.g. with head-worn antennas, modeling is challenging and design goals for optimal antennas are difficult to determine. Therefore, in this paper, the modeling of WBAN channels using spherical wave functions (SWF) is utilized for antenna de-embedding and for deriving optimal antenna characteristics that maximize the transmission coefficient for the respective channel. It is evaluated how typical factors influencing WBAN channels (different body anatomies, body postures, and varying positions of the communication nodes), can be modeled statistically with SWF. An optimized antenna design is developed based on the derived optimization method, specifically adapted to the channel of on-body links with eye-wear applications. The results with the optimized antenna are compared to other standard antenna designs and validated against measurements.
On the convergence of stochastic primal-dual hybrid gradient

Year: 2019
Subjects: subject: Optimization and Control (math.OC)

description: In this paper, we analyze the recently proposed stochastic primal-dual hybrid gradient (SPDHG) algorithm and provide new theoretical results. In particular, we prove almost sure convergence of the iterates to a solution with convexity and linear convergence with further structure, using standard step sizes independent of strong convexity or other regularity constants. In the general convex case, we also prove the $\mathcal{O}(1/k)$ convergence rate for the ergodic sequence, on expected primal-dual gap function. Our assumption for linear convergence is metric subregularity, which is satisfied for strongly convex-strongly concave problems in addition to many nonsmooth and/or nonstrongly convex problems, such as linear programs, Lasso, and support vector machines. We also provide numerical evidence showing that SPDHG with standard step sizes shows a competitive practical performance against its specialized strongly convex variant SPDHG-$μ$ and other state-of-the-art algorithms including variance reduction methods.

description: Future wireless networks are expected to evolve towards an intelligent and software reconfigurable paradigm enabling ubiquitous communications between humans and mobile devices. They will be also capable of sensing, controlling, and optimizing the wireless environment to fulfill the visions of low-power, high-throughput, massively-connected, and low-latency communications. A key conceptual enabler that is recently gaining increasing popularity is the Holographic Multiple Input Multiple Output Surface (HMIMOS) that refers to a low-cost transformative wireless planar structure comprising of sub-wavelength metallic or dielectric scattering particles, which is capable of impacting electromagnetic waves according to desired objectives. In this article, we provide an overview of HMIMOS communications by introducing the available hardware architectures for reconfigurable such metasurfaces and their main characteristics, as well as highlighting the opportunities and key challenges in designing HMIMOS-enabled communications.

description: Superconductivity in infinite-layer nickelates holds exciting analogies with that of cuprates, with similar structures and $3d$-electron count. Using resonant inelastic x-ray scattering (RIXS) we studied electronic and magnetic excitations and charge density correlations in Nd$_{1-x}$Sr$_{x}$NiO$_2$ thin films with and without an SrTiO$_3$ capping layer. We observe dispersing magnons only in the capped samples, progressively dampened at higher doping. In addition, we detect an elastic resonant scattering peak in the uncapped $x=0$ compound at wave vector (1/3,0), remindful of the charge order signal in hole doped cuprates. The peak weakens at $x=0.05$ and disappears in the superconducting $x=0.20$ film. The uncapped samples also present a higher degree of Ni$3d$-Nd$5d$ hybridization and a smaller anisotropy of the Ni$3d$ occupation with respect to the capped samples. The role of the capping on the possible hydrogen incorporation or on other mechanisms responsible for the electronic reconstruction far from the interface remains to be understood.

description: We extensively explore three different aspects of Born-Infeld (BI) type nonlinear $U(1)$ gauge-invariant modifications of Maxwell's classical electrodynamics (also known as BI-type nonlinear electrodynamics) and bring some new perspectives on these theories. First, within the framework of exponential $U(1)$ gauge theory, it is explicitly proved that although the electric field at the location of the elementary point charges is not finite, but the total electrostatic field energy is finite. Motivated by this observation together with a wealth of evidence, we conjecture that all theories in 4-dimensional spacetime that belong to the BI family result in finite self-energy for elementary charged particles. In higher dimensions, it is found that the weak-field coupling limit of BI-type theories, which is identified as the weak field limit of effective Euler-Heisenberg (EH) theory, does not possess a regularizing ability to make the self-energy of a point charge finite, which implies that the conjecture may not hold for some BI-type theories. However, we explicitly prove that BI, logarithmic and exponential $U(1)$ gauge theories in arbitrary dimensions result in finite self-energy as well. Next, we classically study the problem of vacuum polarization effects and then systematically make a connection between all BI-type theories and QED. It is shown that all the BI-type theories classically predict the vacuum polarization effects, in which the final results are exactly in one-to-one correspondence with QED and the effective EH theory up to the leading order of corrections. Finally, we present a new, simple proof indicating that ...

description: Adoption of recently developed methods from machine learning has given rise to creation of drug-discovery knowledge graphs (KG) that utilize the interconnected nature of the domain. Graph-based modelling of the data, combined with KG embedding (KGE) methods, are promising as they provide a more intuitive representation and are suitable for inference tasks such as predicting missing links. One common application is to produce ranked lists of genes for a given disease, where the rank is based on the perceived likelihood of association between the gene and the disease. It is thus critical that these predictions are not only pertinent but also biologically meaningful. However, KGs can be biased either directly due to the underlying data sources that are integrated or due to modeling choices in the construction of the graph, one consequence of which is that certain entities can get topologically overrepresented. We demonstrate the effect of these inherent structural imbalances, resulting in densely-connected entities being highly ranked no matter the context. We provide support for this observation across different datasets, models as well as predictive tasks. Further, we present various graph perturbation experiments which yield more support to the observation that KGE models can be more influenced by the frequency of entities rather than any biological information encoded within the relations. Our results highlight the importance of data modeling choices, and emphasizes the need for practitioners to be mindful of these issues when interpreting model outputs and during KG composition.

Benjamini-Schramm convergence and spectrum of random hyperbolic surfaces of high genus

description: We study geometric and spectral properties of typical hyperbolic surfaces of high genus, excluding a set of small measure for the Weil-Petersson probability measure. We first prove Benjamini-Schramm convergence to the hyperbolic plane H as the genus g goes to infinity. An estimate for the number of eigenvalues in an interval [a,b] in terms of a, b and g is then proven using the Selberg trace formula. It implies the convergence of spectral measures to the spectral measure of H as g $\rightarrow$+$\infty$, and a uniform Weyl law as b $\rightarrow$+$\infty$. We deduce a bound on the number of small eigenvalues, and the multiplicity of any eigenvalue.

description: We study the out-of-time-order correlation (OTOC) of the Floquet transverse Ising model and use it to verify the phase diagram of the system. First, we present the exact analytical solution of the transverse magnetization OTOC using the Jorden-Wigner transformation. We calculate the speed of correlation propagation and analyze the behavior of the revival time with the separation between the observables. In order to get the phase structure of the Floquet transverse Ising system, we use the longitudinal magnetization OTOC as it is known to serve as an order parameter of the system. We show the phase structure numerically in the transverse Ising Floquet system by using the long time average of the longitudinal magnetization OTOC. In both the open and the closed chain systems, we find distinct phases out of which two are paramagnetic (0-paramagnetic and $π$-paramagnetic), and two are ferromagnetic (0-ferromagnetic and $π$-ferromagnetic) as defined in the literature.

Cosmopolitan Citizenship Education: Realistic Political Program or Program to Disillusioned Powerlessness? A Plea for a Critical Power Perspective within Global Citizenship Education
Creators: name: Eis, Andreas
name: Moulin-Doos, Claire
Publisher: name: sowi-online e.V., Bielefeld
Year: 2018

description: Purpose: The aim of the research is to determine to what extent one can talk about “cosmopolitan citizenship” not only programmatically, but also as an already functioning entity. And what role can and should civic education play in the development of such a citizenship?

Methods: A working definition of citizenship at the national, supranational, and global level is developed with the help of political theory and European and international law. Several theses on the understanding of cosmopolitan citizenship in Global Citizenship Education and Education for Sustainable Development programs are discussed thanks to a policy analysis of, for example, UNESCO documents.

Findings: Supranational programs and German curriculum-recommendations are mostly reduced to the level of rights-holders and if “political action” is envisaged then it is mostly focused on its individual dimension of (private) social responsibility i.e. in its post-political dimension. This lacks analysis of global power conflicts and of the question of democratic participation on supranational policy regulation.

Practical implications: There are implications for curriculum development and implementation of educational policy.

description: We introduce and study the notions of boundary actions and of the Furstenberg boundary of a discrete quantum group. As for classical groups, properties of boundary actions turn out to encode significant properties of the operator algebras associated with the discrete quantum group in question; for example we prove that if the action on the Furstenberg boundary is faithful, the quantum group C*-algebra admits at most one KMS-state for the scaling automorphism group. To obtain these results we develop a version of Hamana's theory of injective envelopes for quantum group actions, and establish several facts on relative amenability for quantum subgroups. We then show that the Gromov boundary actions of free orthogonal quantum groups, as studied by Vaes and Vergnioux, are also boundary actions in our sense; we obtain this by proving that these actions admit unique stationary states. Moreover, we prove these actions are faithful, hence conclude a new unique KMS-state property in the general case, and a new proof of unique trace property when restricted to the unimodular case. We prove equivalence of simplicity of the crossed products of all boundary actions of a given discrete quantum group, and use it to obtain a new simplicity result for the crossed product of the Gromov boundary actions of free orthogonal quantum groups.

description: Recently, the reconfigurable intelligent surface (RIS), benefited from the breakthrough on the fabrication of programmable meta-material, has been speculated as one of the key enabling technologies for the future six generation (6G) wireless communication systems scaled up beyond massive multiple input multiple output (Massive-MIMO) technology to achieve smart radio environments. Employed as reflecting arrays, RIS is able to assist MIMO transmissions without the need of radio frequency chains resulting in considerable reduction in power consumption. In this paper, we investigate the joint design of transmit beamforming matrix at the base station and the phase shift matrix at the RIS, by leveraging recent advances in deep reinforcement learning (DRL). We first develop a DRL based algorithm, in which the joint design is obtained through trial-and-error interactions with the environment by observing predefined rewards, in the context of continuous state and action. Unlike the most reported works utilizing the alternating optimization techniques to alternatively obtain the transmit beamforming and phase shifts, the proposed DRL based algorithm obtains the joint design simultaneously as the output of the DRL neural network. Simulation results show that the proposed algorithm is not only able to learn from the environment and gradually improve its behavior, but also obtains the comparable performance compared with two state-of-the-art benchmarks. It is also observed that, appropriate neural network parameter settings will improve significantly the performance and convergence rate of the proposed algorithm.

Färbung im Leben (nach Adloff, „Bl.“ 1922, p. 133):.Auf dem sandsar- bigen Grunde heben ftch 9 schwoarze Quer- bänder wirkungsvoll ab, diefe Querbänder greifen fogar ein wenig auf die tiefblauen schwarzumrandeten grozen Rückenund Afterflossen über. Blau stnd auch die winzig kleinen Bauchflossen und die Schwanzflosse. Bauch(?)flossen (foll wohl heizen: Brustflossen) farblos, aber schwarz umsäumt, die Strahlen der Bertikalflossen heben fich dunkel vom blauen Grunde ab, so daz diese Strahlen wie eine Strichel- zeichnung wirkn. Die Kehle und die Kiemendeckel find leuchtend türkisblau. * Schräg nach vorne durch das Auge ver- läuft ebenfalls ein schwarzer Streifen. Die Schuppen zart verwischt, dunkel um- randet, so daz der Körper wie mit einer Nezzeichnung überzogen erscheint der Rücken zeigt eine etwas dunklere Tönung. Das Weibchen ist von anspruchsloser Fär- bung, die Grundfarbe wie beim Männ- chen, nur matter, mit schwach grauen Querbinden; die Bauchpartie weizlichgelb, in der Schwanzwurzel zwei scharf um- grenzte schwarze Flecken, umgeben von einem hellen Hof. Sonst fehlt am ganzen Körper die das Männchen so zierende Türkisfarbe.“ Über Haltung und Zucht siehe „Bl.“ 1922, p. 134.

description: Quantifying the similarity between a group of companies has proven to be useful for several purposes, including company benchmarking, fraud detection, and searching for investment opportunities. This exercise can be done using a variety of data sources, such as company activity data and financial data. However, ledger account data is widely available and is standardized to a large extent. Such ledger accounts within a financial statement can be represented by means of a tree, i.e. a special type of graph, representing both the values of the ledger accounts and the relationships between them. Given their broad availability and rich information content, financial statements form a prime data source based on which company similarities or distances could be computed. In this paper, we present a graph distance metric that enables one to compute the similarity between the financial statements of two companies. We conduct a comprehensive experimental study using real-world financial data to demonstrate the usefulness of our proposed distance metric. The experimental results show promising results on a number of use cases. This method may be useful for investors looking for investment opportunities, government officials attempting to identify fraudulent companies, and accountants looking to benchmark a group of companies based on their financial statements.

description: Purpose: The Québec Ministry of Education has introduced – as of September 2017 – a new mandatory course focusing on financial literacy and addressing such issues as credit scores, loans, taxes and budgets. This announcement has created intense educational debate on the raison d’être and content of the course. This article will summarise the heated debate and will examine content knowledge and the type of ‘good’ citizens that the course seeks to create.

Method: We use thematic content analysis to identify textual patterns and themes in the Québec Education Program (QEP) pertaining to financial literacy.

Findings: Our assumption is that the QEP reproduces and shapes a personally responsible citizen at the expense of systemic criticism and justice-oriented citizenship education, according to Westheimer and Kahne (2004)’s typology.

description: Band topology has been studied as a design principle of realizing robust boundary modes. Here, by exploring non-Hermitian topology, we propose a three-dimensional topological laser that amplifies surface modes. The topological surface laser is protected by nontrivial topology around branchpoint singularities known as exceptional points. In contrast to two-dimensional topological lasers, the proposed three-dimensional setup can realize topological boundary modes without judicious gain at the edge or symmetry protection, which are thus robust against a broad range of disorders. We also propose a possible optical setup to experimentally realize the topological surface laser. Our results provide a general guiding principle to construct non-Hermitian topological devices in three-dimensional systems.

description: Robotic teleoperation will allow us to perform complex manipulation tasks in dangerous or remote environments, such as needed for planetary exploration or nuclear decommissioning. This work proposes a novel telemanipulation architecture using a passive Fractal Impedance Controller (FIC), which does not depend upon an active viscous component for stability guarantees. Compared to a traditional impedance controller in ideal conditions (no delays and maximum communication bandwidth), our proposed method yields higher transparency in interaction and demonstrates superior dexterity and capability in our telemanipulation test scenarios. We also validate its performance with extreme delays up to 1 s and communication bandwidths as low as 10 Hz. All results validate a consistent stability when using the proposed controller in challenging conditions, regardless of operator expertise.

description: Motivated by the observations of intracellular phase separations and the wetting of cell membranes by protein droplets, we study the nonequilibrium surface wetting by Monte Carlo simulations of a lattice gas model involving particle creation. We find that, even when complete wetting should occur in equilibrium, the fast creation of particles can hinder the surface wetting for a long time due to the bulk droplet formation. Performing molecular dynamics simulations, we show that this situation also holds in colloidal particle systems when the disorder density is sufficiently high. The results suggest an intracellular control mechanism of surface wetting by changing the speed of component synthesis.

title: Climatic Fluctuations in the Early and Middle Copper Age - First Isotope Investigations at the Water Supply of Los Millares in SE Spain

description: The Copper Age fortification of Los Millares is located 15 km north of Almería in Andalusia. At least between 3,541 BC (+/- 92 years) and 2,591 BC (+/- 22 years) there existed a water conduit, the so-called "aqueduct of Los Millares", with which water was conveyed to the settlement from a spring located about 1.25 km outside. U and Sr isotope analyses of groundwater samples in the catchment area as well as of the calcareous sinter deposits of the conduit provided evidence that a mixture of thermal water and near-surface groundwater had flowed in. An interpretation of the climate on the basis of the 13C/12C and 18O/16O ratios of the sinters is therefore not straightforward. However, climatic information can be obtained. The calcareous sinter from the area of the spring, which was formed at the end of the Copper Age or at the beginning of the Bronze Age, during the so-called 4.2 ka cal BP event, showed a percentage increase of the thermal water content of the spring water, which can be explained by a less groundwater recharge of the near-surface water during the long-lasting drought. By means of Sr isotope investigations of all aqueduct sinters, precisely dated paleoclimate data of the early and middle Copper Age can be obtained. So far, these have only been carried out on four sinter samples. For further investigations of climatic fluctuations based on Sr isotope ratios, 56 sinter samples from the aqueduct and the spring are available. A corresponding study is in preparation.
Finance-Informed Citizens, Citizen-Informed Finance: An Essay Occasioned by the International Handbook of Financial Literacy
Creators: name: Willis, Lauren E.
Publisher: name: sowi-online e.V., Bielefeld
Year: 2018

description: Purpose: Throughout the world, the dominant discourse treats “financial literacy” as both necessary and sufficient to improve the well-being of individuals and society.

Findings: This essay argues that financial literacy is neither, and that promoting financial literacy is a perverse way to address the inadequate retirement funding, overindebtedness, financial crises, and other social ills that have inspired governments and educators to pursue it. In its place, this essay suggests that the aim of financial education ought to be to foster finance-informed citizens, who have the capacity for civic engagement that can create citizen-informed economic policies and financial regulation.

description: We prove prime geodesic theorems counting primitive closed geodesics on a compact hyperbolic 3-manifold with length and holonomy in prescribed intervals, which are allowed to shrink. Our results imply effective equidistribution of holonomy and have both the rate of shrinking and the strength of the error term fully symmetric in length and holonomy.
