Galois coverings of selfinjective algebras by repetitive algebras [PDF]
Transactions of the American Mathematical Society, 1999 Let \(A\) be a basic and connected selfinjective Artin algebra. Then the right and the left socles of \(A\) coincide and are denoted by \(\text{soc }A\). Two selfinjective algebras \(A\) and \(A'\) are called socle-equivalent if the quotient algebras \(A/\text{soc} A\) and \(A'/\text{soc} A'\) are isomorphic.

Demonstration of an All‐Optical AND Gate Mediated by Photochromic Molecules
Advanced Functional Materials, EarlyView.A logic AND gate that runs on photons is demonstrated. It relies on two spatially separated photochromic molecules that work in tandem. Abstract The realization of a photonic logic AND gate, i.e. a logic AND gate that runs on photons rather than electrons, and where all steps are controlled by light, is demonstrated. In a proof‐of‐principle experiment,

An exceptional cluster algebra for Higgs plus jet production
Journal of High Energy PhysicsA recent evaluation of three-loop nonplanar Feynman integrals contributing to Higgs plus jet production has established their dependence on two novel symbol letters. We show that the resulting alphabet is described by a G 2 cluster algebra, enlarging the

Computer Assisted Methods in Engineering and Science, 2020 This paper presents the application of affine numbers to determine the time of concrete cover cracking in reinforced concrete elements from the initiation of the reinforcement corrosion. This issue is crucial for evaluating sustainability and durability

Galois Coverings of Weakly Shod Algebras [PDF]
Communications in Algebra, 2010 We investigate the Galois coverings of weakly shod algebras. For a weakly shod algebra not quasi-tilted of canonical type, we establish a correspondence between its Galois coverings and the Galois coverings of its connecting component. As a consequence, we show that a weakly shod algebra is simply connected if and only if its first Hochschild ...

Advanced Robotics Research, EarlyView.This work presents a state‐adaptive Koopman linear quadratic regulator framework for real‐time manipulation of a deformable swab tool in robotic environmental sampling. By combining Koopman linearization, tactile sensing, and centroid‐based force regulation, the system maintains stable contact forces and high coverage across flat and inclined surfaces.

On four-point connectivities in the critical 2d Potts model
SciPost Physics, 2019 We perform Monte-Carlo computations of four-point cluster connectivities in the critical 2d Potts model, for numbers of states $Q\in (0,4)$ that are not necessarily integer.

On the Hilbert series of vertex cover algebras of unmixed bipartite graphs [PDF]
, 2010 We compute the reduced Gr\"{o}bner basis of the toric ideal with respect to a suitable monomial order and we study the Hilbert series of the vertex cover algebra $A(G)$, where $G$ is an unmixed bipartite graph without isolated vertices.Comment: 8 ...

A Perspective on Interactive Theorem Provers in Physics
Advanced Science, EarlyView.Into an interactive theorem provers (ITPs), one can write mathematical definitions, theorems and proofs, and the correctness of those results is automatically checked. This perspective goes over the best usage of ITPs within physics and motivates the open‐source community run project PhysLean, the aim of which is to be a library for digitalized physics
