Multi-region optimal energy storage arbitrage

Md Umar Hashmi · Harsha Nagarajan · Dirk Van Hertem

The increasing interconnection of power systems through AC and DC links enables energy storage units to access multiple electricity markets yet most existing arbitrage models remain limited to singlemarket participation This gap restricts understanding of the economic value and operational constraints associated with c...

Chiral magnons in altermagnetic hexagonal MnTe

Edward MERCER · Liam SCHMIDT · Rikkie JORIS · Alberto DE LA TORRE · y 1 más

Altermagnets are a new class of magnetic materials exhibiting strong time‐reversal symmetry‐breaking responses, akin to ferromagnets, alongside a fully compensated magnetization typical of collinear antiferromagnets (AFM). Altermagnets are predicted to be ideal platforms for THz spintronic devices due to their tunable...

Counting algebraic points of bounded degree on curves

Matias Alvarado

Let $X$ be a smooth projective curve over a number field $k$. Let $f\colon X \to \mathbb{P}^1$ be a non-constant morphism that realizes the gonality of $X$. In this article we study the growth rate of $\left\{P\in X\left(\overline{k} \right)\left| [k(x):k]=ν, k(x)=k(f(x)), h(x)\leq T \right.\right\}.$

Patrimonio culinario mexicano y banalización cultural: análisis de restaurantes en Barcelona

Oleg Lazovski · Gaspar Berbel · Rafael Paramo

Mexican cuisine, recognised by UNESCO as Intangible Cultural Heritage of Humanity, constitutes a living and territorially diverse culinary system that faces risks of trivialisation when projected internationally. This article analyses the extent to which the offering of Mexican restaurants in Barcelona acts as an authe...

Hair as a window to mood disorders: Discrimination of bipolar affective disorder using mapping spectroscopy

Magdalena Świądro-Piętoń · Gabriela Tajduś · Aleksandra Zając · Paweł Sroga · y 2 más

This study explores the applicability of hair as a non-invasive matrix for the spectroscopic assessment of mood disorders. Hair specimens were collected from individuals diagnosed with: recurrent depressive disorder or depressive episodes, mixed anxiety and depressive disorders, and bipolar affective disorder, alongsid...

Multi-period sparse optimization for proactive grid blackout diagnosis

Qinghua Ma · Reetam Sen Biswas · Denis Osipov · Guannan Qu · y 2 más

Existing or planned power grids need to evaluate survivability under extreme events, like a number of peak load overloading conditions, which could possibly cause system collapses (i.e. blackouts). For realistic extreme events that are correlated or share similar patterns, it is reasonable to expect that the dominant v...

Discovery of sparse invariant subgrid-scale closures via dissipation-controlled training for large eddy simulation on anisotropic grids

Samantha Friess · Aviral Prakash · John A. Evans

Neural networks offer highly expressive turbulence closures, yet their complexity obscures the physical mechanisms they aim to model, and their computational cost can limit their tractability. To address these limitations, we introduce a sparsity-promoting subgrid-scale (SGS) stress closure modeling framework that iden...

A natural fuzzy order on fuzzy numbers

Kou, Hui · Xie, Mingchun

This paper introduces a natural fuzzy order on fuzzy numbers that extends the natural orders on real numbers and interval numbers. We investigate its completeness properties and show that the space of uniformly bounded fuzzy numbers is conically complete and conically cocomplete, and that it is complete if and only if...

Zero-gap cell for CO2 reduction reaction

Valentin VINCI · Jakub DRNEC · Hridya NEDUMKULAM · Marta MIROLO · y 1 más

Investigation of the catalyst evolution and flooding of a newly designed zero-gap cell for CO2 reduction reaction via operando measurements and wide-angle X-ray scattering computed tomography
