description: In this paper, we study a distributed continuous-time design for aggregative games with coupled constraints in order to seek the generalized Nash equilibrium by a group of agents via simple local information exchange. To solve the problem, we propose a distributed algorithm based on projected dynamics and non-smooth tracking dynamics, even for the case when the interaction topology of the multi-agent network is time-varying. Moreover, we prove the convergence of the non-smooth algorithm for the distributed game by taking advantage of its special structure and also combining the techniques of the variational inequality and Lyapunov function.

description: In this paper, we consider distributed optimization design for resource allocation problems over weight-balanced graphs. With the help of singular perturbation analysis, we propose a simple sub-optimal continuous-time optimization algorithm. Moreover, we prove the existence and uniqueness of the algorithm equilibrium, and then show the convergence with an exponential rate. Finally, we verify the sub-optimality of the algorithm, which can approach the optimal solution as an adjustable parameter tends to zero.

description: Inference of latent feature models in the Bayesian nonparametric setting is generally difficult, especially in high dimensional settings, because it usually requires proposing features from some prior distribution. In special cases, where the integration is tractable, we can sample new feature assignments according to a predictive likelihood. We present a novel method to accelerate the mixing of latent variable model inference by proposing feature locations based on the data, as opposed to the prior. First, we introduce an accelerated feature proposal mechanism that we show is a valid MCMC algorithm for posterior inference. Next, we propose an approximate inference strategy to perform accelerated inference in parallel. A two-stage algorithm that combines the two approaches provides a computationally attractive method that can quickly reach local convergence to the posterior distribution of our model, while allowing us to exploit parallelization.

Food safety and market choice of dairy producers in Bangladesh

subject: FOS: Economics and business

description: Dairy production is an important income generating activity for smallholders in Bangladesh. However, milk production in Bangladesh is known to be of poor average quality and high losses due to limited and heterogeneous milk hygiene and food safety practices on farms and during milk collection. Dairy farmers in three agro-ecological zones of Bangladesh were surveyed in order to analyze their choice of dairy markets in relation to their food safety practices. After controlling for farm and household characteristics, physical infrastructure, type of delivery relationships and nominal milk prices received, we find that a particular group of farmers tends to maintain relatively high levels of food safety practices while receiving above average milk prices. Surprisingly, these farmers tend to choose local or traditional markets due to the absence of formal incentives for high food safety practices in cooperatives or among private dairy processors. Instead, informal institutions likely enable dairy farmers with above average food safety standards to negotiate higher prices in the local village surroundings. Regarding the transformation of Bangladesh’s dairy sector towards more productivity, this finding highlights the importance to implement formal testing procedures and establish price related incentives that will reward above average food safety and milk hygiene.

description: In this article, we show that in each of four standard families of hyperelliptic curves, there is a density-$1$ subset of members with the property that their Jacobians have adelic Galois representation with image as large as possible. This result constitutes an explicit application of a general theorem on arbitrary rational families of abelian varieties to the case of families of Jacobians of hyperelliptic curves. Furthermore, we provide explicit examples of hyperelliptic curves of genus $2$ and $3$ over $\mathbb Q$ whose Jacobians have such maximal adelic Galois representations.

description: We prove that the positive fragment of first-order intuitionistic logic in the language with two variables and a single monadic predicate letter, without constants and equality, is undecidable. This holds true regardless of whether we consider semantics with expanding or constant domains. We then generalise this result to intervals [QBL, QKC] and [QBL, QFL], where QKC is the logic of the weak law of the excluded middle and QBL and QFL are first-order counterparts of Visser's basic and formal logics, respectively. We also show that, for most "natural" first-order modal logics, the two-variable fragment with a single monadic predicate letter, without constants and equality, is undecidable, regardless of whether we consider semantics with expanding or constant domains. These include all sublogics of QKTB, QGL, and QGrz -- among them, QK, QT, QKB, QD, QK4, and QS4.

description: The object of this paper is to study $η$-Ricci solitons on $(\varepsilon)$-almost paracontact metric manifolds. We investigate $η$-Ricci solitons in the case when its potential vector field is exactly the characteristic vector field $ξ$ of the $(\varepsilon)$-almost paracontact metric manifold and when the potential vector field is torse-forming. We also study Einstein-like and $(\varepsilon)$-para Sasakian manifolds admitting $η$-Ricci solitons. Finally we obtain some results for $η$-Ricci solitons on $(\varepsilon)$-almost paracontact metric manifolds with a special view towards parallel symmetric (0,2)-tensor fields.

Review and suggested resolution of the problem of Schrodinger's cat
Creators: name: Hobson, Art
Publisher: name: arXiv
Year: 2017
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: This paper reviews and suggests a resolution of the problem of definite outcomes of measurement. This problem, also known as "Schrodinger's cat," has long posed an apparent paradox because the state resulting from a measurement appears to be a quantum superposition in which the detector is in two macroscopically distinct states (alive and dead in the case of the cat) simultaneously. Many alternative interpretations of the quantum mathematical formalism, and several alternative modifications of the theory, have been proposed to resolve this problem, but no consensus has formed supporting any one of them. Applying standard quantum theory to the measurement state, together with the analysis and results of decades of nonlocality experiments with pairs of entangled systems, this paper shows the entangled measurement state is not a paradoxical macroscopic superposition of states. It is instead a phase-dependent superposition of correlations between states of the subsystems. Thus Schrodinger's cat is a non-paradoxical "macroscopic correlation" in which one of the two correlated systems happens to be a detector. This insight resolves the problem of definite outcomes but it does not entirely resolve the measurement problem because the entangled state is still reversible.

description: Beitrag im Sammelband «Praxeologie in der Historischen Bildungsforschung: Möglichkeiten und Grenzen eines Forschungsansatzes» 10.5281/zenodo.4045831. Dem Spannungsverhältnis von Kontrollregimen und Eigensinn der Zöglinge an Zürcher Lehrerseminaren und Erziehungsanstalten im späten 19. und frühen 20. Jahrhundert widmet sich der Beitrag von Norbert Grube. Inwieweit Eigensinn als individuelle Widerständigkeit und auch als gleichzeitig widersprüchliches und vieldeutiges Verhalten entlang institutionalisierter Praktiken von Unterricht und ordnenden Kontroll- und Alltagsroutinen im Seminar erinnert, dargestellt und ein Stück weit auch erfahren worden ist, wird anhand von Ego-Dokumenten analysiert. Mit Ausnahme der handschriftlichen Erinnerungen des Zürcher Lehrers Alfred Traber werden dabei autobiografisch geprägte Romane genutzt, deren Autoren – Jakob Christoph Heer, Jakob Schaffner, aber auch Hermann Hesse und Erich Kästner – ihren Besuch in unterschiedlichen Seminaren und damit verbundenen Erziehungsanstalten literarisch thematisiert haben. Quellenkritisch und im Hinblick auf praxeologische Zugangsweisen zu prüfen ist, inwieweit fiktive Literatur Autorenerfahrungen aufgreift und zugleich diskursive Muster hinsichtlich seminaristischer Lehrerbildung, etwa marktgängige Bilder von der Unterwerfung der Heranwachsenden in einer Kontroll- und Strafinstitution, verarbeitet. Diese methodisch-konzeptionelle Reflexion wird vertieft, indem ergänzend herangezogene Protokolle der Aufsichtskommission und des Lehrerkonvents aus dem Archivbestand des Seminars Küsnacht auf die aus den Ego-Dokumenten gewonnenen Analysebefunde quellenkritisch bezogen werden. Was sagen die unterschiedlichen Quellenarten über Wahrnehmung und Erinnerung von Eigensinn und Praktiken am Seminar aus? Indem die Zöglinge mehrschichtigen Ebenen von sozialer Kontrolle ausgesetzt sind, sowohl der Beobachtung und Bewertung der Lehrer sowie ihrer Freunde als auch zirkulierender Wissen im Seminar und in dessen städtischem Umfeld, wird abschliessend mit wissensgeschichtlicher Perspektive untersucht, inwieweit unterschiedliche institutionelle bzw. (teil-)öffentliche Erwartungen und Wissensordnungen Eigensinn und verschiedene, auch miteinander konfligierende Praktiken bedingen. Oder verweist vermeintlicher Eigensinn des Subjekts letztlich weniger auf individuelle Aneignung, als auf Kollisionen verschiedener, jeweils auf unterschiedlichen (Wissens-)Kontexten beruhender Praktiken?

description: Associated to the Bergman kernels of a polarized toric \kahler manifold $(M, ω, L, h)$ are sequences of measures $\{μ_k^z\}_{k=1}^{\infty}$ parametrized by the points $z \in M$. For each $z$ in the open orbit, we prove a central limit theorem for $μ_k^z$. The center of mass of $μ_k^z$ is the image of $z$ under the moment map; after re-centering at $0$ and dilating by $\sqrt{k}$, the re-normalized measure tends to a centered Gaussian whose variance is the Hessian of the \kahler potential at $z$. We further give a remainder estimate of Berry-Esseen type. The sequence $\{μ_k^z\}$ is generally not a sequence of convolution powers and the proofs only involve \kahler analysis.

description: Poly(styrene-co-maleic anhydride) (SMA) was reacted with 4-amino-6-methyl-3-thioxo-1,2,4-triazine-5-one to obtain the corresponding imide [SMI] which was used as a substrate for immobilization of PdCl2 and preparation of palladium nanoparticles (PdNPs). The supported PdNPs were fully characterized using scanning electron microscopy (SEM), energy dispersive X-ray (EDAX) and FTIR spectroscopy, and inductively coupled plasma spectrometry (ICP). The catalytic efficiency of the PdNPs was evaluated examined successfully in one the established and useful reaction so-called the Suzuki cross-coupling reaction involving the reaction of various aryl halides with phenylboronic acid in water. The advantages of this procedure include easy recovery and efficient reusability of the expensive PdNPs, high yields of the cross coupled products, short reaction times, and use of water as a green solvent for a wide range of substrates.

The class of so-called $w^*$-locally relatively compact sets was introduced recently by Fonf, Pallares, Troyanski and the author, and were found to be a useful topological tool in the theory of isomorphic smoothness and polyhedrality in Banach spaces. We develop the topological theory of these sets and present some Banach space applications.

In the gradient case we give an estimation of the Ricci curvature tensor's norm and express the scalar curvature of the manifold in terms of the functions that define the soliton. We also prove that if the Ricci operator is Codazzi, then the gradient $η$-Ricci soliton is expanding if $M$ is spacelike or shrinking if $M$ is timelike.

description: Relatively recently it was proved that if $Γ$ is an arbitrary set, then any equivalent norm on $c_0(Γ)$ can be approximated uniformly on bounded sets by polyhedral norms and $C^\infty$ smooth norms, with arbitrary precision. We extend this result to more classes of spaces having uncountable symmetric bases, such as preduals of the `discrete' Lorentz spaces $d(w,1,Γ)$, and certain symmetric Nakano spaces and Orlicz spaces. We also show that, given an arbitrary ordinal number $α$, there exists a scattered compact space $K$ having Cantor-Bendixson height at least $α$, such that every equivalent norm on $C(K)$ can be approximated as above.

description: Beitrag im Sammelband «Praxeologie in der Historischen Bildungsforschung: Möglichkeiten und Grenzen eines Forschungsansatzes» 10.5281/zenodo.4045831. Durch Adrian Juens Beitrag wird das Tun einer bisher wenig beachteten Personengruppe zum Gegenstand einer praxeologischen Untersuchung. Die Hauswarte bildeten – teilweise als ›doppelte Einheit‹ mit ihren Ehefrauen – eine Akteurskonstellation, die durch ihre spezifischen Praktiken das Seminar und eine Seminarkultur überhaupt erst im Sinne der ›Vorgängigkeit‹ ermöglichten. Werden Quellen untersucht, die sich mittel- oder unmittelbar mit Hauswartstätigkeiten um 1900 befassen, entsteht ein komplexeres Bild von Zusammenspiel und ›Aushandlung‹ durch Praktiken verschiedener Akteure am Seminar. Technik und technische Neuerungen, etwa Zentralheizungen und elektrische Anlagen, gaben am Lehrerseminar Küsnacht des Kantons Zürich gewisse Raumordnungen und Spielregeln für alltägliche Hauswartsroutinen sowie auch für den Hauswartskörper vor. Juen entfaltet, wie Verschränkungen zwischen Technik, Routinen und Reglementen, die immer wieder einem Wandel und Anpassungen unterlagen, das Berufsbild prägten und den in diesen Rahmungen agierenden Akteuren Handlungsmuster und Wissen bereitstellten. Die Frage nach dem eigensinnigen und intentionalen resp. nichtintentionalen Charakter von Praktiken stellt sich, wenn etwa der Hauswart an der Höheren Töchterschule und dem Lehrerinnenseminar der Stadt Zürich sich darum bemüht, vom Arbeitgeber einen Wachhund bezahlt zu bekommen. Diesbezügliche Korrespondenzen scheinen als Kommunikationsort auf, an dem die Grenzen der Zusammenarbeitsroutinen zwischen Hauswart, Direktion und Anstellungsbehörden durch Verweise auf Gefahrenabwehr und Polizeidienst ausgehandelt wurden. Hauswartspraktiken erwiesen sich nicht nur als ein technikaffines Handlungsfeld, sondern konnten sich auch mit dem Unterricht oder mit der Produktion von Ratgeberliteratur verquicken. Zugleich kann der Beitrag als historische, praxistheoretische und methodologische Anreicherung der erziehungswissenschaftlich geprägten Diskussion zu Schulkulturen gelesen werden.

The hypotheses of both results are based on decomposing the unit sphere of a Banach space into countably many pieces, such that each one satisfies certain properties. Some examples of spaces having equivalent polyhedral norms are given.

description: In the first part, we define and investigate new classes of almost 3-contact metric manifolds, with two guiding ideas in mind: first, what geometric objects are best suited for capturing the key properties of almost 3-contact metric manifolds, and second, the newly defined classes should admit 'good' metric connections with skew torsion. In particular, we introduce the Reeb commutator function and the Reeb Killing function, we define the new classes of canonical almost 3-contact metric manifolds and of 3-$(α,δ)$-Sasaki manifolds (including as special cases 3-Sasaki manifolds, quaternionic Heisenberg groups, and many others) and prove that the latter are hypernormal, thus generalizing a seminal result by Kashiwada. We study their behaviour under a new class of deformations, called $\mathcal{H}$-homothetic deformations, and prove that they admit an underlying quaternionic contact structure, from which we deduce the Ricci curvature. For example, a 3-$(α,δ)$-Sasaki manifold is Einstein either if $α=δ$ (the 3-$α$-Sasaki case) or if $δ=(2n+3)α$, where $\dim M=4n+3$. The second part is actually devoted to finding these adapted connections. We start with a very general notion of $φ$-compatible connections, where $φ$ denotes any element of the associated sphere of almost contact structures, and make them unique by a certain extra condition, thus yielding the notion of canonical connection (they exist exactly on canonical manifolds, hence the name). For 3-$(α,δ)$-Sasaki manifolds, we compute the torsion of this connection explicitly and we prove that it is parallel, we describe the holonomy, the $\nabla$-Ricci curvature, and we show that the metric cone is a HKT-manifold. In dimension 7, we construct a cocalibrated $G_2$-structure inducing the canonical connection and we prove the existence of four generalized Killing spinors.

description: We study the properties of a generalized metallic, a generalized product and a generalized complex structure induced on the generalized tangent bundle of $M$ by a metallic Riemannian structure $(J,g)$ on $M$, providing conditions for their integrability with respect to a suitable connection. Moreover, by using methods of generalized geometry, we lift $(J,g)$ to metallic Riemannian structures on the tangent and cotangent bundles of $M$, underlying the relations between them.

description: We prove a topological extension of Dirac's theorem suggested by Gowers in 2005: for any connected, closed surface $\mathscr{S}$, we show that any two-dimensional simplicial complex on $n$ vertices in which each pair of vertices belongs to at least $n/3 + o(n)$ facets contains a homeomorph of $\mathscr{S}$ spanning all the vertices. This result is asymptotically sharp, and implies in particular that any 3-uniform hypergraph on $n$ vertices with minimum codegree exceeding $n/3+o(n)$ contains a spanning triangulation of the $2$-sphere.

description: Given a non-degenerate $(0,2)$-tensor field $h$ on a smooth manifold $M$, we consider a natural generalized complex and a generalized product structure on the generalized tangent bundle $TM\oplus T^*M$ of $M$ and we show that they are $\nabla$-integrable, for $\nabla$ an affine connection on $M$, if and only if $(M,h,\nabla)$ is a quasi-statistical manifold. We introduce the notion of generalized quasi-statistical structure and we prove that any quasi-statistical structure on $M$ induces generalized quasi-statistical structures on $TM\oplus T^*M$. In this context, dual connections are considered and some of their properties are established. The results are described in terms of Patterson-Walker and Sasaki metrics on $T^*M$, horizontal lift and Sasaki metrics on $TM$ and, when the connection $\nabla$ is flat, we define prolongation of quasi-statistical structures on manifolds to their cotangent and tangent bundles via generalized geometry. Moreover, Norden and Para-Norden structures are defined on $T^*M$ and $TM$.

description: Using natural materials, i.e. halloysite nanoclay that is a biocompatible naturally occurring clay and Heracleum persicum extract that can serve as a green reducing agent, a novel magnetic catalyst, Fe3O4/Hal-Mel-TEA(IL)-Pd, has been designed and fabricated. To prepare the catalyst, halloysite was first magnetized (magnetic particles with mean diameter of 13.06 ± 3.1 nm) and then surface functionalized with melamine, 1,4 dibromobutane and triethanolamine to provide ionic liquid on the halloysite surface (5 wt%). The latter was then used as a support to immobilize Pd nanoparticles that were reduced by Heracleum persicum extract. The characterization of the catalyst established that the loading of Pd in Fe3O4/Hal-Mel-TEA(IL)-Pd was very low (0.93 wt%) and its specific surface area was 63 m2g−1. Moreover, the catalyst showed magnetic property (Ms = 19.75 emu g−1) and could be magnetically separated from the reaction. The catalytic performance of the magnetic catalyst for reductive degradation of methyl orange and rhodamine B in the presence of NaBH4 in aqueous media was investigated. The activation energy, enthalpy, and entropy for the reduction of methyl orange were estimated as 42.02 kJ mol−1, 39.40 kJ mol−1, and −139.06 J mol−1 K−1, respectively. These values for rhodamine B were calculated as 39.97 kJ mol−1, 34.33 kJ mol−1, and −155.18 Jmol−1K−1, respectively. Notably, Fe3O4/Hal-Mel-TEA(IL)-Pd could be reused for eight reaction runs with negligible loss of the catalytic activity (~3%) and Pd leaching (0.01 wt% of the initial loading).

description: Unawareness of the risk factors is one of the most important issues that need to be settled for stroke prevention. We aimed to evaluate the awareness of risk factors for cerebrovascular diseases (CVDs) among acute ischemic stroke patients and to investigate the characteristics of patients who were unaware of their risk factors in Shenzhen, China. Registered data on awareness of CVD risk factors of patients with confirmed acute ischemic stroke (AIS) from June 2020 to December 2022 were analyzed in May 2023. The data were extracted from the database of Shenzhen Quality Control Center for Management of Cerebrovascular Diseases. Totally, there were 5147 AIS patients with complete data eligible for this study. AIS patients’ awareness regarding existing hypertension, diabetes, dyslipidemia, and atrial fibrillation (AF) was 76.1%, 76.2%, 24.2%, and 53.4%, respectively. Patients who were lack of awareness of the CVD risk factors were more likely to be males, individuals with younger ages, and those without medical insurance or a CVD history. The overall awareness of the CVD risk factors was suboptimal among AIS patients in Shenzhen, especially for the existing dyslipidemia. The health education of AIS should be further improved in males as well as individuals without medical insurance or any CVD histories. Age was an independent factor associated with the lack of awareness of the CVD risk factors. The stroke screening program should be extended to younger people.

description: We conjecture that the set of homogeneous probability measures on the maximal Satake compactification of an arithmetic locally symmetric space $S=Γ\backslash G/K$ is compact. More precisely, given a sequence of homogeneous probability measures on $S$, we expect that any weak limit is homogeneous with support contained in precisely one of the boundary components (including $S$ itself). We introduce several tools to study this conjecture and we prove it in a number of cases, including when $G={\rm SL}_3(\mathbb{R})$ and $Γ={\rm SL}_3(\mathbb{Z})$.

Praktiken des Trinkens in Schülervereinen der Küsnachter Seminaristen zu Beginn des 20. Jahrhunderts: Überlegungen zum Fokus auf Praktiken als Möglichkeit einer radikalen Historisierung

description: Beitrag im Sammelband «Praxeologie in der Historischen Bildungsforschung: Möglichkeiten und Grenzen eines Forschungsansatzes» 10.5281/zenodo.4045831. Als die Seminargemeinschaft gefährdend wurde die im Beitrag von Andrea De Vincenti fokussierte »Fidelitas«, eine abstinente Vereinigung von Zöglingen am Kantonalen Lehrerseminar Küsnacht, angesehen, während andere Zöglingsvereinigungen am Seminar nicht nur gebilligt, sondern gar breite Unterstützung durch Lehrerkonvent und Direktor erfuhren. Ausgehend von der Feststellung, dass Praktiken des Trinkens von Alkohol im Turnverein gebilligt, in der »Fidelitas« aber umgehend sanktioniert wurden und letztlich zu ihrer Auflösung führten, fragt die Autorin nach den jeweiligen Trinkpraktiken und den Gründen für die zwei so unterschiedlichen Umgangsweisen der Seminarleitung mit diesen Praktiken, respektive mit den sie praktizierenden Vereinen. Mit einer durch unterschiedliche Quellengattungen gegebenen mehrperspektivischen Auswertung der Praktiken des Trinkens im sanktionierten Verein sowie des Umgangs mit dem Verein und der Vereinszugehörigkeit einzelner Zöglinge des Seminars arbeitet De Vincenti die spezifischen Sinn- und Bedeutungsstrukturen der auf den ersten Blick mit dem anderen Verein überlappenden Trinkpraktiken heraus. Obwohl in beiden Vereinen das Trinken als gesellige Praxis etabliert und fest verankert war, können die jeweils unterschiedlichen sinnhaften Codierungen Aufschlüsse darüber geben, weshalb das Trinken einmal als legitim, einmal aber als Grund für harsche Sanktionen erschien. Anhand von theoretischen Überlegungen zu Praktiken, die eng auf das Fallbeispiel bezogen werden, plausibilisiert der Beitrag schliesslich die These, dass es keine Praktik des Trinkens per se geben könne, sondern jede Praktik stets nur in ihrem spezifischen Kontext, das heisst unter Berücksichtigung der stets orts- und zeitspezifischen Sinn- und Bedeutungsstrukturen, zu verstehen sei – auch wenn sie vordergründig, also auf der wahrnehmbaren körperlich-materialen Ebene, vielleicht identisch mit anderen erscheint. Vor dem Hintergrund dieser Überlegungen sieht die Autorin in einer praxeologischen Perspektive die Möglichkeit einer radikalen Historisierung: Praktiken seien erst durch eine möglichst vielperspektivische Kontextualisierung in ihrer »Doppelstruktur« (Reckwitz) von einerseits direkt wahrnehmbaren Bewegungen und Äusserungen und andererseits darin codierten Wissens- und Bedeutungsstrukturen zu erfassen, sodass Letztere immer auf den konkreten historischen Fall verwiesen.

description: We construct motives over the rational numbers associated with symmetric power moments of Kloosterman sums, and prove that their L-functions extend meromorphically to the complex plane and satisfy a functional equation conjectured by Broadhurst and Roberts. Although the motives in question turn out to be "classical", we compute their Hodge numbers by means of the irregular Hodge filtration on their realizations as exponential mixed Hodge structures. We show that all Hodge numbers are either zero or one, which implies potential automorphy thanks to recent results of Patrikis and Taylor.
description: v2: Results and exposition improved. v3: Substantial revision after referee reports. The main construction now takes place in the setting of exponential mixed Hodge structures. We partially reorganized the material and removed one of the appendices. Some statements have been strengthened, several proofs simplified, and a few mistakes corrected. v5: Final published version
