String topology for Lie groups [PDF]
Journal of Topology, 2010 In 1999 Chas and Sullivan showed that the homology of the free loop space of an oriented manifold admits the structure of a Batalin-Vilkovisky algebra. In this paper we give a direct description of this Batalin-Vilkovisky algebra in the case that the manifold is a compact Lie group G. Our answer is phrased in terms of the homology of G, the homology of

Harnessing Machine Learning to Understand and Design Disordered Solids
Advanced Intelligent Discovery, EarlyView.This review maps the dynamic evolution of machine learning in disordered solids, from structural representations to generative modeling. It explores how deep learning and model explainability transform property prediction into profound physical insight.

A Novel Linear Circuit For Current Equalization In Led Strings
Eletrônica de Potência, 2013 This paper deals with the problem of current sharing in parallel strings of LEDs. As there is no guarantee that the string voltages are the same, some strategy for equalizing their currents must be used.

Advanced Intelligent Discovery, EarlyView.A machine learning framework simultaneously predicts four critical properties of monomers for emulsion polymerization: propagation rate constant, reactivity ratios, glass transition temperature, and water solubility. These tools can be used to systematically identify viable bio‐based monomer pairs as replacements for conventional formulations, with ...

Worldsheet formalism for decoupling limits in string theory
Journal of High Energy PhysicsWe study the bosonic sector of a decoupling limit of type IIA superstring theory, where a background Ramond-Ramond one-form is fined tuned to its critical value, such that it cancels the associated background D0-brane tension.

Regge limit of one-loop string amplitudes
SciPost PhysicsWe study the high-energy limit of $2 \to 2$ one-loop string amplitudes at fixed momentum transfer. For the closed string, the high-energy behavior of the amplitudes can be determined from Regge theory just like in field theory, as was first discussed by ...

Animal Research and One Health, EarlyView.This study delineates the early sex differentiation timeline in the northern snakehead (Channa argus). These findings provide a foundation for future sex‐control breeding in this economically important species. ABSTRACT The northern snakehead (Channa argus) is an economically important aquaculture species in China.

Finite temperature Casimir effect for a spinor field in cosmic dispiration spacetime
Journal of High Energy PhysicsThis study explores the finite temperature Casimir effect for a massive spinor field in cosmic dispiration spacetime, formed by the combination of a cosmic string and a screw dislocation, using the generalized zeta function regularization method.

Chemistry – A European Journal, EarlyView.ABSTRACT Molecules that violate Hund's rule by exhibiting an inverted singlet–triplet gap (STG), where the first excited singlet (S1${\rm S}_1$) lies below the triplet (T1${\rm T}_1$), are rare but hold great promise as efficient fifth‐generation light emitters.

Other Classes of Generalized Compact Spaces Based on New Generalized ω-Open Sets [PDF]
مجلة جامعة الانبار للعلوم الصرفةThe concept of generalized compactness is very useful and essential concept not only in general topology but also in the other advanced branches of pure and applied mathematics.
