Comprehensive X-ray study of giant radio galaxies with XMM-Newton and Chandra

Niraj Maurya · Satish S. Sonkamble · Suraj Dhiwar · M.B. Pandge · y 2 más

We present a systematic X-ray spectral analysis of 27 giant radio galaxies (GRGs) using archival \textit{XMM-Newton} and \textit{Chandra} data. Roughly 44\% of the sample show intrinsic absorption ($N_{\mathrm{H,int}} \gtrsim 10^{21}\,\mathrm{cm}^{-2}$), while several exhibit narrow Fe K$α$ emission lines with equivale...

Many (most?) column subset selection criteria are NP hard for a few columns

Ilse C.F. Ipsen · Arvind K. Saibaba

We consider a variety of criteria for selecting k representative columns from a real mxn matrix A, when sufficiently few columns are required, i.e., 1<= k<= min{rank(A), m/3}. The criteria include the following optimization problems: absolute volume and S-optimality maximization; norm, pseudo-inverse norm, and conditio...

Where should control sit? Reliability-cost trade-offs in delegating water distribution network optimisation to LLM agents

Jian Wang · Shuming Liu · Guangtao Fu · Dragan Savic

Computational optimisation is now routinely used to support the design and operation of water distribution networks (WDNs). However, formulating optimisation problems, configuring solution workflows and interpreting results still depend heavily on manual effort, making even standard studies time-consuming to reproduce...

Curve reconstruction in inverse problems: From divergence-measure vector fields to density Lebesgue measures

Tsafack, Anéva Doliciane · Blanc-Féraud, Laure · Aubert, Gilles

Nous présentons un nouveau cadre variationnel pour la reconstruction de courbes en problèmes inverses, formulé via l’optimisation de champs de vecteurs. Le problème est défini dans un espace de mesures vectorielles absolument continues par rapport à la mesure de Lebesgue, avec des densités de type Sobolev. Dans ce cadr...

Annihilators of (co)homology and their influence on the trace ideal

Justin Lyle · Sarasij Maitra

Let $(R,\mathfrak{m})$ be a commutative Noetherian local ring, and suppose $R$ is Cohen-Macaulay with canonical module $ω_R$. We develop new tools for analyzing questions involving annihilators of several homologically defined objects. Using these, we study a generalization introduced by Dao-Kobayashi-Takahashi of the...

Exploring the effect of vitamin D on the inflammatory microenvironment of breast tumor in the context of obesity using an in vitro 3D triculture model

Aoun, Jessy · Habanjar, Ola · Nehme, Rawan · Decombat, Caroline · y 7 más

Obesity is a recognized risk factor for breast cancer, the leading cause of cancer death worldwide. Vitamin D (vit D), a molecule with anti-inflammatory effects, can act on different cell types through the presence of its VDR receptor. Our aim was therefore to study the impact of vit D in a 3D co-culture model between...

Another look at the control properties of the Korteweg-de Vries equation

Roberto de A. Capistrano-Filho · Fernando Gallego

This paper represents a new perspective in understanding the controllability of the Korteweg-de Vries (KdV) equation on unbounded domains. By studying the equation on both the right and left half-line with a single control input, we show that a class of solutions exists for which the KdV equation is exactly controllabl...

The European Battery Hub

Irina PROFATILOVA · Ambroise VAN ROEKEGHEM · David PERALTA · Jan JAMROZ · y 10 más

This project is the continuation of the Battery Pilot Hub (MA4929), a pioneer initiative at ESRF designed to achieve large-scale synchrotron-based correlative characterization of battery materials (2021-24). The European Battery Hub is the demonstrator of this new community-driven approach, where we will develop, expan...
