BCH and LCD cyclic codes of length n = λ(qm + 1) over finite fields

Jinle Liu · Hongfeng Wu · Li Zhu

BCH and LCD cyclic codes of length $n=λ(q^m+1)$ with $λ\mid q-1$ are studied. A complete characterization of $q$-cyclotomic cosets modulo $n$ is given: Theorem \ref{th4} provides a necessary and sufficient condition for any $0\le γ

Mordell-Tornheim multiple zeta-functions, their integral analogues, and relations among multiple polylogarithms

Matsumoto, Kohji · Onodera, Kazuhiro · Sahoo, Dilip K.

We study the asymptotic behavior of a multiple series of Mordell-Tornheim type and its integral analogue at x=0. Our approach is to show a relation between the multiple series and its integral analogue by using Abel's summation formula, and to deeply investigate the behavior of the integral analogue. Additionally, we e...

Darboux first integrals of Kolmogorov systems with invariant n-sphere

Jana, Supriyo · Sarkar, Soumen

In this paper, we characterize all polynomial Kolmogorov vector fields for which the standard $n$-sphere is invariant. We exhibit completely integrable Kolmogorov vector fields of degree $m$ on $\mathbb{S}^n$ for any $m >2$. Then, we show that there is no cubic Hamiltonian Kolmogorov vector field that makes an odd-dime...

Endogenies and linearisation

Deloro, Adrien · Wagner, Frank Olaf

We show that the action of two infinite commuting invariant rings of endomorphisms of a finite-dimensional virtually connected irreducible bi-module linearizes into a vector space over a definable field. The same holds if the action is merely by strongly commuting endogenies, modulo some finite katakernel.

Simplifying preference elicitation in local energy markets: Combinatorial clock exchange

Shobhit Singhal · Lesia Mitridati

As distributed energy resources (DERs) proliferate, future power system will need new market platforms enabling prosumers to trade various electricity and grid-support products. However, prosumers often exhibit complex, product interdependent preferences and face limited cognitive and computational resources, hindering...

Recommendations for the initial management of septicshock in children

Guillermo, Kohn-Loncarica · Josefina, Pérez · Gustavo A, González · Roberto, Jabornisky · y 2 más

We present an update on recommendations for managing septic shock in the emergency department during the "golden hour," highlighting the importance of early recognition and rapid implementation of therapeutic measures to reduce morbidity and mortality. It includes specific diagnostic criteria (the Phoenix Sepsis Scale)...

Nonlinear diffusion limit of non-local interactions on a sphere

Mark A. Peletier · Anna Shalova

We study an aggregation PDE with competing attractive and repulsive forces on a sphere of arbitrary dimension. In particular, we consider the limit of strongly localized repulsion with a constant attraction term. We prove convergence of solutions of such a system to solutions of the aggregation-diffusion equation with...

On amenability and LEF-ness for topological full groups

Ma, Xin

In this paper, we prove that for a topologically free distal action $α$ of a countable discrete group $G$ on the Cantor set, the topological full group $[[α]]$ is amenable if and only if $G$ is amenable. This generalizes a result by Cortez and Medynets. In addition, we obtain negative results on the amenability of topo...

Byzantine-robust distributed sparse learning revisited

Yuxuan Wang · Lixin Zhang · Kangqiang Li

We revisit Byzantine robust distributed estimation for high-dimensional sparse linear models. By combining local $\ell_1$-regularized robust estimation with robust aggregation at the server, the framework applies to pseudo-Huber regression, quantile regression, and sparse SVM. We show that the resulting estimators yiel...

Microscopic anatomy of the heart and aortic crest of the sea hare Aplysia depilans (Gastropoda: Euopisthobranchia)

Alexandre, Lobo-da-Cunha

The heart of the sea hare Aplysia depilans, located within the pericardial cavity, consists of an auricle and a ventricle connected to an aortic crest. The auricular epicardium is composed of thin, flattened epithelial cells containing vesicles that may be involved in transport by transcytosis between the heart lumen a...
