Moore–Gibson–Thompson Stability Model in a Two-Temperature Photonic Semiconductor Excited Medium Affected by Rotation and Initial Stress

open access: yesCrystals, 2022
In this paper, the two-temperature theory is used to examine a novel model that generalizes the Moore–Gibson–Thompson (MGT) effect according to two-dimensional electronic/thermoelastic deformation.

Thermal-Diffusive Processes of an Electron-Hole Non-Local Semiconductor Model with Variable Thermal Conductivity and Hall Current Effect

open access: yesMathematics, 2023
In this work, a novel model is presented that describes thermal diffusion processes through non-local semiconductor materials. The material under study is subjected to the influence of a strong magnetic field, which creates a Hall current.

The biHecke monoid of a finite Coxeter group and its representations [PDF]

open access: yes, 2012
For any finite Coxeter group W, we introduce two new objects: its cutting poset and its biHecke monoid. The cutting poset, constructed using a generalization of the notion of blocks in permutation matrices, almost forms a lattice on W.

Three Hopf algebras from number theory, physics & topology, and their common background I: operadic & simplicial aspects [PDF]

open access: yesCommunications in Number Theory and Physics, 2016
We consider three a priori totally different setups for Hopf algebras from number theory, mathematical physics and algebraic topology. These are the Hopf algebra of Goncharov for multiple zeta values, that of Connes-Kreimer for renormalization, and a ...

A Bayesian homogeneity test for comparing Poisson populations

open access: yesApplied Stochastic Models in Business and Industry, Volume 38, Issue 6, Page 1158-1171, November/December 2022., 2022
Abstract For a wide class of daily applications in industrial quality control, there may be interest in comparing several Poisson means. A large catalogue of frequentist procedures for this hypothesis testing problem is available. However, some common drawbacks of them are their low power, interpretation of the p$$ p $$‐values for multiple comparison ...

Probabilistic logics based on Riesz spaces [PDF]

open access: yesLogical Methods in Computer Science, 2020
We introduce a novel real-valued endogenous logic for expressing properties of probabilistic transition systems called Riesz modal logic. The design of the syntax and semantics of this logic is directly inspired by the theory of Riesz spaces, a mature ...

Isomorphisms between the Batalin-Vilkovisky antibracket and the Poisson bracket [PDF]

open access: yes, 1996
One may introduce at least three different Lie algebras in any Lagrangian field theory : (i) the Lie algebra of local BRST cohomology classes equipped with the odd Batalin-Vilkovisky antibracket, which has attracted considerable interest recently~; (ii ...

Twisted Supergravity and Koszul Duality: A Case Study in AdS₃ [PDF]

open access: yes, 2020
In this note, we study a simplified variant of the familiar holographic duality between supergravity on AdS₃ × S³ × T⁴ and the SCFT (on the moduli space of) the symmetric orbifold theory Sym^N(T⁴) as N→∞.

Bayesian Parameterization of Continuum Battery Models from Featurized Electrochemical Measurements Considering Noise**

open access: yesBatteries &Supercaps, Volume 6, Issue 1, January 2023., 2023
We introduce a computer algorithm that incorporates the experience of battery researchers to extract information from experimental data reproducibly. This enables the fitting of complex models that take up to a few minutes to simulate. For validation, we process full‐cell GITT measurements to characterize the diffusivities of both electrodes non ...

Photo-thermoelastic wave propagation with changing thermal conductivity on excited pulsed laser nanoscale microelongated semiconductor material

open access: yesFrontiers in Physics, 2023
Indroduction: The novel model of a non-local elastic semiconductor material that is microelongated is created. The process of photothermal transfer is responsible for the stimulation of the material. Photo-thermoelastic theories are used when the thermal
