In many quantum applications it is important to know whether or not a Bell nonlocal two-qudit state exhibits its nonlocality under correlation scenarios with some given numbers S1,S2≥1 of generalized quantum measurements at two sites. In the present article, we find analytically a new general locality condition sufficient for a nonseparable Werner state with a ...

Chow polylogarithms are some special functions arising in explicit description of the Beilinson regulator map. The most interesting functional equation for this function reflects its vanishing on the boundary in the Bloch's cycle complex. We show that this functional equation formally follows from more simple ones, namely skew-symmetry, functoriality and multiplicativity.
To prove this, we study ...

Let K be a field of characteristic zero. We prove that its motivic cohomology in degree m−1 and weight m is rationally isomorphic to the cohomology of the polylogarithmic complex. This gives a partial extension of A. Suslin theorem describing the indecomposable K3 of a field. ...

This paper investigates the problem of statistical inference for a mixture distribution consisting of a discrete and a continuous component, with a particular focus on the class of rational-infinitely divisible distributions. We consider non-parametric estimation of both components of the mixture as well as the quasi-L{é}vy measure, assuming that the mixture belongs to the class ...

A noncommutative projective variety is defined, following Artin and Zhang, by a graded coherent algebra 𝐴. The category of coherent sheaves is then the quotient qgr(𝐴) of the category of finitely presented graded modules by the subcategory of torsion modules. We consider the categorical and polynomial entropies of the Serre twist, that is, of the ...

If a symmetric multilinear algebra is weakly nil, then it is Engel. This result may be regarded as an infinite-dimensional analogue of the well-known Jacobian theorem, which states that if a polynomial mapping has a polynomial inverse, then its Jacobian matrix is invertible. This refines a theorem of Gerstenhaber and partially answers a question posed ...

In this paper, we construct strong approximations for discrete-time Markov chains weakly converging to continuous diffusion processes, as well as for their perturbed counterparts. Under the assumption of bounded coefficients, we construct closely coupled versions of these processes on a shared probability space. In particular, for both non-degenerate and degenerate cases, we maximize the probability ...

A fast simulation of the detector response is a vital task in high-energy physics (HEP). Traditional Monte-Carlo methods form the backbone of modern particle physics simulation software but are computationally expensive. We present a machine-learning-based approach to fast simulation of the Focusing Aerogel Ring Imaging Cherenkov (FARICH) detector response. Given a particle track and momentum, ...

In this paper the structural stability of generic families of vector fields of the PC-HC class on the two-dimensional sphere is proved. A classification of these families up to moderate equivalence in neighborhoods of their large bifurcation supports is presented, based on such invariants as the configuration and the characteristic set. The realization lemma is proved. ...

A vertex subset of a graph is called a \textit{distance-$k$ independent set} if the distance between any two of its distinct vertices is at least $k + 1$. For all $n,k \geq 1$, we determine the minimum possible number of inclusion-wise maximal distance-$k$ independent sets among all $n$-vertex trees. It equals~$n$ if $n \leq k ...

We introduce an explicit class of tempered Laurent polynomials in the sense of Villegas and Doran--Kerr in n⩽4 variables including all Landau--Ginzburg models for smooth Fano threefolds with very ample anticanonical class. We check that it contains Landau--Ginzburg models for various Fano fourfolds which are complete intersections in smooth toric varieties and Grassmannians of planes, ...

Comprehensive data on natural hazards and their consequences are crucial for effective for risk assessment, adaptation planning, and emergency response. However, many countries face challenges with fragmented, inconsistent, and inaccessible data, particularly regarding local-scale events. To address this data gap in Russia, we developed an end-to-end processing pipeline that scrapes news from various online sources, ...

We investigate the spatial overlap of successive spin configurations in Markov chain Monte Carlo simulations using the local Metropolis algorithm and the Svendsen-Wang and Wolff cluster algorithms. We examine the dynamics of these algorithms for two models in different universality classes: the Ising model and the Potts model with three components. The overlap of two ...

We deal with the global in time weak solutions to the 1D compressible Navier-Stokes system of equations for large discontinuous initial data and nonhomogeneous boundary conditions of three standard types. We prove the Lipschitz-type continuous dependence of the solution $(\eta,u,\theta)$, in a norm slightly stronger than $L^{2,\infty}(Q)\times L^2(Q)\times L^2(Q)$, on the initial data $(\eta^0,u^0,e^0)$ in a ...

Statistical evaluation of three-dimensional auto- and cross-correlation functions for increments from the first guess was performed to interpolate the complex forecast (postprocessing) of geopotential height and temperature to regular grid points. The forecast fields from the ICON model were used as the first guess. Positive definiteness was provided in the evaluation. The verification of the ...

Transportation systems are complicated and deal with significant problems. With the pool of possible solutions being wide, extensive transportation planning has to be involved. However, planning based on expert opinions is significantly limited in terms of rapidity, accuracy, and confidence. Computer-aided design and automated decision-making systems are the next step to ensure transportation system development ...

The article announces an analogy of using transport equilibrium models in the problems of distributing computer
network flows. The purpose of the study is to test the possibility of using transport models and algorithms to optimize routing in a software-defined network (SDN) and to build an optimal flow distribution method based on these models. To achieve this goal, integer optimization and computer modeling methods were used. ...

This paper presents an analysis of a new method for retrieving the parameters of the atmospheric boundary layer in hurricanes. This method is based on the approximation of the upper parabolic part of the wind speed profile and the retrieval of the lower logarithmic part.

Описывается исследование возможности реализации виртуальных сетей с учётом различных параметров и их корректировки в программно-конфигурируемых структурах, моделируемых взвешенным графом плоскости данных. В работе исследуются параметры двух типов: «ресурс» и «стоимость». Для параметра типа «ресурс» с ребром ассоциируется его «ёмкость», и число путей, проходящих через ребро, не должно превышать ёмкость ребра. Для параметра типа «стоимость» с ...

Как практикующие историки приходят к тем или иным убеждениям? Как отличить «гипотетическое» от «доказанного»? Почему в определенный момент те или иные интерпретации находят всеобщую поддержку в научном сообществе, а другие нет? И как в дальнейшем общепризнанные интерпретации могут быть опровергнуты?

Многосторонние соглашения используются в системах распределенного реестра и блокчейн-сетях для согласования изменений в системе. Если один из участников сети предлагает транзакцию на запись, то сначала ее должны подтвердить определенные участники сети. Многостороннее соглашение, или консенсус, определяет состав этих участников. На основе предыдущих ответов можно посчитать вероятность подтверждения транзакции для каждого из участников. В настоящей работе ...

Степень применения методов формальной верификации в индустриальных проектах всегда была ограничена. Распространение систем распределенного реестра (СРР), известных также как блокчейн, быстро меняет ситуацию. Поскольку основной областью применения СРР является автоматизация финансовых транзакций, свойства предсказуемости и надежности являются критическими при реализации таких систем. Реальное поведение СРР определяется выбранным протоколом консенсуса, свойства которого нуждаются в строгой спецификации ...
