description: Biological processes, from morphogenesis to tumor invasion, spontaneously generate shear stresses inside living tissue. The mechanisms that govern the transmission of mechanical forces in epithelia and the collective response of the tissue to bulk shear deformations remain, however, poorly understood. Using a minimal cell-based computational model, we investigate the constitutive relation of confluent tissues under simple shear deformation. We show that an initially undeformed fluidlike tissue acquires finite rigidity above a critical applied strain. This is akin to the shear-driven rigidity observed in other soft matter systems. Interestingly, shear-driven rigidity can be understood by a critical scaling analysis in the vicinity of the second order critical point that governs the liquid-solid transition of the undeformed system. We further show that a solidlike tissue responds linearly only to small strains and but then switches to a nonlinear response at larger stains, with substantial stiffening. Finally, we propose a mean-field formulation for cells under shear that offers a simple physical explanation of shear-driven rigidity and nonlinear response in a tissue.

description: It can be observed that there has been an increasing focus on alternative development models in regional and nationalgovernance to accelerate India’s upward thrust in the knowledge era. Business, Government and Non-GovernmentOrganisations (NGOs) are looking for new concepts and methods to operate so that true development happens withan inclusive strategic intent. International Association for Human Values (IAHV), an international humanitarianand educational non-governmental organization founded in 1997 in Geneva by H.H. Sri Sri Ravi Shankar, maintainsspecial consultative status with the Economic, Social and Cultural Council (ECOSOC) of the United Nations andworks with its sister organisation, the International Art of Living Foundation in five main areas related to sustainabledevelopment while uplifting individuals and communities at the grassroots, so that they become self-reliant, bothsocially and economically. The various projects initiated in this line aims to eradicate poverty, misery, disease and toensure peace and harmony in rural and tribal areas worldwide. The youth from the local community undergo theYouth Leadership Training Program (YLTP), which gives them the skills, motivation and abilities to initiate and leadservice projects in their own villages and localities based on their needs. This paper presents a unique model for developmentbased on the wide range of activities under theYLTP programon empowering individuals to attain sustainabledevelopment solutions in progressing towards a knowledge society.

description: Passive implementations of quantum key distribution (QKD) sources are highly desirable as they eliminate side-channels that active modulators might introduce. Up till now, passive decoy-state and passive encoding BB84 schemes have both been proposed. Nonetheless, passive decoy-state generation and passive encoding have never been simultaneously implemented with linear optical elements before, which greatly limits the practicality of such passive QKD schemes. In this work, we overcome this limitation and propose a fully-passive QKD source with linear optics that eliminates active modulators for both decoy-state choice and encoding. This allows for highly practical QKD systems that avoid side-channels from the source modulators. The passive source we propose (combined with the decoy-state analysis) can create any arbitrary state on a qubit system and is protocol-independent. That is, it can be used for various protocols such as BB84, reference-frame-independent QKD, or the six-state protocol. It can also in principle be combined with e.g. measurement-device-independent QKD, to build a system without side-channels in either detectors or modulators.
Asymptotic variance of grey-scale surface area estimators

description: Grey-scale local algorithms have been suggested as a fast way of estimating surface area from grey-scale digital images. Their asymptotic mean has already been described. In this paper, the asymptotic behaviour of the variance is studied in isotropic and sufficiently smooth settings, resulting in a general asymptotic bound. For compact convex sets with nowhere vanishing Gaussian curvature, the asymptotics can be described more explicitly. As in the case of volume estimators, the variance is decomposed into a lattice sum and an oscillating term of at most the same magnitude.

description: Symmetric trace-free tensors are used in many areas of physics, including electromagnetism, relativistic celestial mechanics and geodesy, as well as in the study of gravitational radiation and gravitational lensing. Their use allows integration of the relevant wave propagation equations to arbitrary order. We present an improved iterative method for the trace-free decomposition of symmetric tensors of arbitrary rank. The method can be used both in coordinate-free symbolic derivations using a computer algebra system and in numerical modeling. We obtain a closed-form representation of the trace-free decomposition in arbitrary dimensions. To demonstrate the results, we compute the coordinate combinations representing the symmetric trace-free (STF) mass multipole moments for rank 5 through 8, not readily available in the literature.

Does International Integration Reduce Corruption? Theory And Evidence From Lithuania
Creators: name: Greenaway, Bowen
Publisher: name: University of Chicago
Year: 2023

description: In the early 2000s, corruption permeated almost every facet of daily life in Lithuania. Yet, by the next decade, Lithuania’s successes in combatting corruption were being heralded as a template for other nations. How did this occur? Extensive research has demonstrated that international integration may reduce domestic corruption; this paper examines whether integration had the same impact in Lithuania. We examine two mechanisms associated with international integration, the processes of norm development and economic growth, arguing that, together, they facilitated the rapid decrease of corruption in Lithuania. To explore this relationship, we conduct a document and literature analysis, finding that periods of anti-corruption reform were closely linked to the aspirations for deeper EU integration. We then adapt Bai et al.’s (2013) corruption and inter-regional competition model and apply it to Lithuania. Using survey data collected from over 900 Lithuanian firms between 2002 and 2018 and an Instrumental Variable (IV) strategy based on a Bartik shift-share instrument, we find that economic growth decreased the commonality of bribe extraction in Lithuania. We also find that this effect was greater for more mobile firms and industries that were better prepared to take advantage of increased integration. This paper’s results suggest that the normative and economic mechanisms associated with international integration contributed to a reduction in corruption in Lithuania and, more broadly, contribute to a growing subfield of literature on the political economy of corruption.

description: The ability to perform computation on devices, such as smartphones, cars, or other nodes present at the Internet of Things leads to constraints regarding bandwidth, storage, and energy, as most of these devices are mobile and operate on batteries. Using their computational power to perform locally machine learning and analytics tasks can enable accurate and real-time predictions at the network edge. A trained machine learning model requires high accuracy towards the prediction outcome, as wrong decisions can lead to negative consequences on the efficient conclusion of applications. Most of the data sensed in these devices are contextual and personal requiring privacy-preserving without their distribution over the network. When working with these privacy-preserving data, not only the protection is important but, also, the model needs the ability to adapt to regular occurring concept drifts and data distribution changes to guarantee a high accuracy of the prediction outcome. We address the importance of personalization and generalization in edge devices to adapt to data distribution updates over continuously evolving environments. The methodology we propose relies on the principles of Federated Learning and Optimal Stopping Theory extended with a personalization component. The privacy-efficient and quality-awareness of personalization and generalization is the overarching aim of this work.

description: This study aims to identify the factors influencing the perception towards organized retailing from unorganized retailers. The primary data was gathered by administering a prearranged questionnaire with 100 customers selected purposively from Ernakulam District in Kerala. The rationale of the study is twofold: First, to examine the shift in perception in the retail sector taking place due to organized form of retailing. Secondly, the area has remained largely an unexplored part of research till date especially in Ernakulam. The data analysis of customer attitude towards unorganized and organized retailers shows that there is a difference between the consumers’ perception towards both organized retailers and unorganized retailers regarding their store image, range of products, brand choices, price, store atmosphere, credit availability, and shop proximity. The data has been collected with the help of structured questionnaire containing close and open ended questions. Statistical software and MS excel were extensively used for analyzing the data collected.

Photon-assisted absorption of up to 14 photons is observed, when electron temperature (>1K) are far above the lattice temperature. Signatures of Landau-Zener-Stückelberg (LZS) interference are found even in this non-equilibrium PAT spectrum. In addition, the charge state relaxation time T_1~8ns measured in this out of thermal equilibrium double quantum dot is in agreement with other previous reports.

description: Let G be a Lie group and g its Lie algebra. We develop a theory of quasi Poisson structures relative to a not necessarily non-degenerate Ad-invariant symmetric 2-tensor in the tensor square of g and one of general not necessarily non-degenerate quasi Hamiltonian structures relative to a not necessarily non-degenerate Ad-invariant symmetric bilinear form on g, a quasi Poisson structure being given by a skew bracket of two variables such that suitable data defined in terms of G as symmetry group involving the 2-tensor measure how that bracket fails to satisfy the Jacobi identity. The present approach involves a novel concept of momentum mapping and yields, in the non-degenerate case, a bijective correspondence between non-degenerate quasi Poisson structures and non-degenerate quasi Hamiltonian structures. The new theory applies to various not necessarily non-singular moduli spaces and yields thereupon, via reduction with respect to an appropriately defined momentum mapping, not necessarily non-degenerate ordinary Poisson structures. Among these moduli spaces are representation spaces, possibly twisted, of the fundamental group of a Riemann surface, possibly punctured, and moduli spaces of semistable holomorphic vector bundles as well as Higgs bundle moduli spaces. In the non-degenerate case, such a Poisson structure comes down to a stratified symplectic one of the kind explored in the literature and recovers, e.g., the symplectic part of a Kähler structure introduced by Narasimhan and Seshadri for moduli spaces of stable holomorphic vector bundles on a curve. In the algebraic setting, these moduli spaces arise as not necessarily non-singular affine not necessarily non-degenerate Poisson varieties. A side result is an explicit equivalence between extended moduli spaces and quasi Hamiltonian spaces independently of gauge theory.

description: We have recently proposed a simple relativistic theory which reduces to modified Newtonian dynamics for the weak-field quasistatic situations applied to galaxies, and to cosmological behavior as in the $Λ$CDM model, yielding a realistic cosmology in line with observations. A key requirement of any such model is that Minkowski space is stable against linear perturbations. We expand the theory action to second order in perturbations on a Minkowski background and show that it leads to healthy dispersion relations involving propagating massive modes in the vector and the scalar sector. We use Hamiltonian methods to eliminate constraints present, demonstrate that the massive modes have Hamiltonian bounded from below and show that a nonpropagating mode with a linear time dependence may have unbounded Hamiltonian for wave numbers $k< μ$ and bounded otherwise. The scale $μ$ is estimated to be $\lesssim \mathrm{Mpc}^{-1}$ so that the low momenta instability may only play a role on cosmological scales.

Likewise, human factors researchers are increasingly focusing on the role of the patient. Doing research that involves patients can be challenging. Based on the literature and our own experience we illustrate some of these challenges. We also emphasize the benefits of directly involving patients in human factors research.

description: We study the bit complexity of two related fundamental computational problems in linear algebra and control theory. Our results are: (1) An $\tilde{O}(n^{ω+3}a+n^4a^2+n^ω\log(1/ε))$ time algorithm for finding an $ε-$approximation to the Jordan Normal form of an integer matrix with $a-$bit entries, where $ω$ is the exponent of matrix multiplication. (2) An $\tilde{O}(n^6d^6a+n^4d^4a^2+n^3d^3\log(1/ε))$ time algorithm for $ε$-approximately computing the spectral factorization $P(x)=Q^*(x)Q(x)$ of a given monic $n\times n$ rational matrix polynomial of degree $2d$ with rational $a-$bit coefficients having $a-$bit common denominators, which satisfies $P(x)\succeq 0$ for all real $x$. The first algorithm is used as a subroutine in the second one. Despite its being of central importance, polynomial complexity bounds were not previously known for spectral factorization, and for Jordan form the best previous best running time was an unspecified polynomial in $n$ of degree at least twelve \cite{cai1994computing}. Our algorithms are simple and judiciously combine techniques from numerical and symbolic computation, yielding significant advantages over either approach by itself.

description: Numerous studies have examined the associations between long-term exposure to fine particulate matter (PM2.5) and adverse health outcomes. Recently, many of these studies have begun to employ high-resolution predicted PM2.5 concentrations, which are subject to measurement error. Previous approaches for exposure measurement error correction have either been applied in non-causal settings or have only considered a categorical exposure. Moreover, most procedures have failed to account for uncertainty induced by error correction when fitting an exposure-response function (ERF). To remedy these deficiencies, we develop a multiple imputation framework that combines regression calibration and Bayesian techniques to estimate a causal ERF. We demonstrate how the output of the measurement error correction steps can be seamlessly integrated into a Bayesian additive regression trees (BART) estimator of the causal ERF. We also demonstrate how locally-weighted smoothing of the posterior samples from BART can be used to create a more accurate ERF estimate. Our proposed approach also properly propagates the exposure measurement error uncertainty to yield accurate standard error estimates. We assess the robustness of our proposed approach in an extensive simulation study. We then apply our methodology to estimate the effects of PM2.5 on all-cause mortality among Medicare enrollees in New England from 2000-2012.

description: Kurz gefasst:
Die Mindestlöhne in Deutschland werden viel zu häufig umgangen und unterschritten. Besorgniserregend ist, dass die Zahl der anspruchsberechtigten Beschäftigten, denen der Mindestlohn noch vorenthalten wird, weiterhin hoch ist. Nach Berechnungen des DIW erhielten 2016 rund 1,8 Millionen anspruchsberechtigte Personen weniger als 8,50 Euro.
Besonders hoch ist die Nichteinhaltung des Mindestlohns in schwer zu kontrollierenden Kleinstbetrieben und in prekären Beschäftigungsformen. Regelverstöße sind bei Minijobs offensichtlich endemisch. Man kann ihnen nicht allein durch Kontrollen begegnen. Erforderlich ist die Abschaffung des Sonderstatus dieser Beschäftigungsform, die offensichtlich sowohl Beschäftigten als auch Unternehmen das Signal vermittelt, dass auch eine Sonderbehandlung angesagt ist.
Die Beschäftigung ist in den letzten Jahren trotz Mindestlohn weiter im Trend gewachsen. In Einzelfällen ist aber durchaus Personalabbau zu beobachten. So hat die Zahl der geringfügig Beschäftigten abgenommen und wenig produktive Betriebe mussten schließen. Die Gesamtbilanz ist aber eindeutig positiv.

description: Depinning of elastic systems advancing on disordered media can usually be described by the quenched Edwards-Wilkinson equation (qEW). However, additional ingredients such as anharmonicity and forces that can not be derived from a potential energy may generate a different scaling behavior at depinning. The most experimentally relevant is the Kardar-Parisi-Zhang (KPZ) term, proportional to the square of the slope at each site, which drives the critical behavior into the so-called quenched KPZ (qKPZ) universality class. We study this universality class both numerically and analytically: by using exact mappings we show that at least for $d=1,2$ this class encompasses not only the qKPZ equation itself, but also anharmonic depinning and a well-known class of cellular automata introduced by Tang and Leschhorn. We develop scaling arguments for all critical exponents, including size and duration of avalanches. The scale is set by the confining potential strength $m^2$. This allows us to estimate numerically these exponents as well as the $m$-dependent effective force correlator $Δ(w)$, and its correlation length $ρ:= Δ(0)/|Δ'(0^+)|$. Finally we present a new algorithm to numerically estimate the effective ($m$-dependent) elasticity $c$, and the effective KPZ non-linearity $λ$. This allows us to define a dimensionless universal KPZ amplitude ${\cal A}:=ρλ/c$, which takes the value ${\cal A}=1.10(2)$ in all systems considered in $d=1$. This proves that qKPZ is the effective field theory for all these models. Our work paves the way for a deeper understanding of depinning in the qKPZ class, and in particular, for the construction of a field theory that we describe in a companion paper.

description: In [Inventiones mathematicae, 184 (2011)], Vollaard and Wedhorn defined a stratification on the special fiber of the unitary unramified PEL Rapoport-Zink space with signature $(1,n-1)$. They constructed an isomorphism between the closure of a stratum, called a closed Bruhat-Tits stratum, and a Deligne-Lusztig variety which is not of classical type. In this paper, we describe the $\ell$-adic cohomology groups over $\overline{\mathbb Q_{\ell}}$ of these Deligne-Lusztig varieties, where $\ell \not = p$. The computations involve the spectral sequence associated to the Ekedahl-Oort stratification of a closed Bruhat-Tits stratum, which translates into a stratification by Coxeter varieties whose cohomology is known. Eventually, we find out that the irreducible representations of the finite unitary group which appear inside the cohomology contribute to only two different unipotent Harish-Chandra series, one of them belonging to the principal series.

Als Datengrundlage dienten qualitative Interviews, Plenarprotokolle und eine Umfrage unter 90 Ausländerbehörden.
Ausländerbehörden werden überwiegend als „Flaschenhals“ wahrgenommen, beispielsweise wenn es um die Umsetzung gesetzlicher Bestimmungen zu den vielfältigsten Herkunftsländen geht. In 5 Handlungsfeldern haben die drei Wissenschaftler:innen Empfehlungen für die Verbesserung der Situation erarbeitet. Eine davon ist die Vermeidung von Mehrfachprüfungen.

description: Quantum Hall effect (QHE), the ground to construct modern conceptual electronic systems with emerging physics, is often much influenced by the interplay between the host two-dimensional electron gases and the substrate, sometimes predicted to exhibit exotic topological states. Yet the understanding of the underlying physics and the controllable engineering of this paradigm of interaction remain challenging. Here we demonstrate the observation of an unusual QHE, which differs markedly from the known picture, in graphene samples in contact with an anti-ferromagnetic insulator CrOCl equipped with dual gates. Owing to the peculiar interfacial coupling, Landau levels in monolayer graphene remain intact at negative filling fractions, but largely deviated for the positive gate-doping range. The latter QHE phase even presents in the limit of zero magnetic field, with the consequential Landau quantization following a parabolic relation between the displacement field $D$ and the magnetic field $B$. This characteristic prevails up to 100 K in a sufficiently wide effective doping range from 0 to 10$^{13}$ cm$^{-2}$. Our findings thus open up new routes for manipulating the quantum electronic states, which may find applications in such as quantum metrology.

description: We study numerically a model of non-aligning self-propelled particles interacting through steric repulsion, which was recently shown to exhibit active phase separation in two dimensions in the absence of any attractive interaction or breaking of the orientational symmetry. We construct a phase diagram in terms of activity and packing fraction and identify three distinct regimes: a homogeneous liquid with anomalous cluster size distribution, a phase-separated state both at high and at low density, and a frozen phase. We provide a physical interpretation of the various regimes and develop scaling arguments for the boundaries separating them.

description: We consider the renormalization of the three-quark operators without derivatives at next-to-next-to-leading order in QCD perturbation theory at the symmetric subtraction point. This allows us to obtain conversion factors between the $\bar{\rm MS}$ scheme and the regularization invariant symmetric MOM (RI/SMOM, RI${}'$/SMOM) schemes. The results are presented both analytically in $R_ξ$ gauge in terms of a set of master integrals and numerically in Landau gauge. They can be used to reduce the errors in determinations of baryonic distribution amplitudes in lattice QCD simulations.

description: In power systems, one wishes to regulate the aggregate demand of an ensemble of distributed energy resources (DERs), such as controllable loads and battery energy storage systems. We suggest a notion of predictability and fairness, which suggests that the long-term averages of prices or incentives offered should be independent of the initial states of the operators of the DER, the aggregator, and the power grid. We show that this notion cannot be guaranteed with many traditional controllers used by the load aggregator, including the usual proportional-integral (PI) controller. We show that even considering the non-linearity of the alternating-current model, this notion of predictability and fairness can be guaranteed for incrementally input-to-state stable (iISS) controllers, under mild assumptions.

description: Lean production has become a major change strategy in Swedish public
organizations. The aim of this paper was to identify factors that support or counteract sustainability and development of Lean implementations in public organizations. In an interactive research project including interviews and questionnaires, seven public organizations were followed during a three year period. Some factors supported and other factors counteracted sustainability and development of Lean. In conclusion, lack of sustained change was to a large extent due to replacement of the top managers in five of the organizations and introduction of another change philosophy, low political and managerial ownership and financial problems.

description: Cette revue de littérature s’intéresse aux troubles fonctionnels qui sont une problématique de santé fréquente chez les adolescents. Ces troubles altèrent plusieurs sphères importantes dans leur développement social, physique et psychique avec un retentissement sur la dynamique familiale. En effet, les parents sont directement touchés par les défis liés aux troubles fonctionnels des jeunes. De plus, ils présentent différents enjeux pour les professionnels de la santé, tout d’abord au niveau du diagnostic mais aussi de la prise en soin. Ces derniers manquent souvent de connaissances sur le sujet et de ressources pour prendre en soin ces adolescents et leur famille. Le but de ce travail est de s’intéresser aux expériences vécues par les adolescents souffrant de troubles fonctionnels et à celles de leurs parents afin de mieux les comprendre et de mieux pouvoir identifier leurs besoins en matière de soin. Cela permettrait d’esquisser des pistes d’interventions infirmières spécifiques à cette population.

description: Objective: The computation of anatomical information and laparoscope position is a fundamental block of surgical navigation in Minimally Invasive Surgery (MIS). Recovering a dense 3D structure of surgical scene using visual cues remains a challenge, and the online laparoscopic tracking primarily relies on external sensors, which increases system complexity. Methods: Here, we propose a learning-driven framework, in which an image-guided laparoscopic localization with 3D reconstructions of complex anatomical structures is obtained. To reconstruct the 3D structure of the whole surgical environment, we first fine-tune a learning-based stereoscopic depth perception method, which is robust to the texture-less and variant soft tissues, for depth estimation. Then, we develop a dense visual reconstruction algorithm to represent the scene by surfels, estimate the laparoscope poses and fuse the depth maps into a unified reference coordinate for tissue reconstruction. To estimate poses of new laparoscope views, we achieve a coarse-to-fine localization method, which incorporates our reconstructed 3D model. Results: We evaluate the reconstruction method and the localization module on three datasets, namely, the stereo correspondence and reconstruction of endoscopic data (SCARED), the ex-vivo phantom and tissue data collected with Universal Robot (UR) and Karl Storz Laparoscope, and the in-vivo DaVinci robotic surgery dataset, where the reconstructed 3D structures have rich details of surface texture with an accuracy error under 1.71 mm and the localization module can accurately track the laparoscope with only images as input. Conclusions: Experimental results demonstrate the superior performance of the proposed method in 3D anatomy reconstruction and laparoscopic localization. Significance: The proposed framework can be potentially extended to the current surgical navigation system.

description: Circulation is the characteristic feature of successful currency systems, from community currencies to cryptocurrencies to national currencies. In this paper, we propose a network analysis approach especially suited for studying circulation given a system's digital transaction records. Sarafu is a digital community currency that was active in Kenya over a period that saw considerable economic disruption due to the COVID-19 pandemic. We represent its circulation as a network of monetary flow among the 40,000 Sarafu users. Network flow analysis reveals that circulation was highly modular, geographically localized, and occurring among users with diverse livelihoods. Across localized sub-populations, network cycle analysis supports the intuitive notion that circulation requires cycles. Moreover, the sub-networks underlying circulation are consistently degree disassortative and we find evidence of preferential attachment. Community-based institutions often take on the role of local hubs, and network centrality measures confirm the importance of early adopters and of women's participation. This work demonstrates that networks of monetary flow enable the study of circulation within currency systems at a striking level of detail, and our findings can be used to inform the development of community currencies in marginalized areas.

description: Magnetic skyrmions are nanoscale spin whirlpools that promise breakthroughs in future spintronic applications. Controlled generation of magnetic skyrmions by electric current is crucial for this purpose. While previous studies have demonstrated this operation, the topological charge of the generated skyrmions is determined by the direction of the external magnetic fields, thus is fixed. Here, we report the current-induced skyrmions creation in a chiral magnet FeGe nanostructure by using the \emph{in-situ} Lorentz transmission electron microscopy. We show that magnetic skyrmions or antiskyrmions can be both transferred from the magnetic helical ground state simply by controlling the direction of the current flow at zero magnetic field. The force analysis and symmetry consideration, backed up by micromagnetic simulations, well explain the experimental results, where magnetic skyrmions or antiskyrmions are created due to the edge instability of the helical state in the presence of spin transfer torque. The on-demand generation of skyrmions and control of their topology by electric current without the need of magnetic field will enable novel purely electric-controlled skyrmion devices.
