Advancing CO2 Conversion with Cu‐LDHs: A Review of Computational and Experimental Studies

The Chemical Record, EarlyView.
The combination of computational and experimental approaches provides fundamental insights into the electro‐ and photocatalytic conversion of CO2 on complex Layered Double Hydroxide‐based catalysts, enabling to advance the understanding of these critical processes Abstract Layered Double Hydroxides (LDHs) are versatile materials with tuneable ...

The collapsibility of some CAT(0) simplicial complexes of dimension 3 [PDF]

arXiv, 2015
We study the collapsibility of finite simplicial complexes of dimension 3 endowed with a CAT(0) metric. Our main result states that, under an additional hypothesis, finite simplicial 3-complexes endowed with a CAT(0) metric collapse to a point through CAT(0) subspaces.

Modeling fire‐related smoke inhalation injury using the human lung‐on‐a‐chip and organoid platform: Pathogenesis insights and therapeutic evaluation

VIEW, EarlyView.
Fire‐related smoke inhalation‐induced acute lung injury (SI‐ALI) poses a significant public health risk, yet effective treatments are limited due to the lack of suitable models. This study developed a more realistic model of SI‐ALI using organ‐on‐a‐chip and organoid technologies, identified key molecules such as catechol‐O‐methyltransferase and ...

Convergence and collapsing of CAT$(0)$-lattices [PDF]

arXiv
We study the theory of convergence for CAT$(0)$-lattices (that is groups $\Gamma$ acting geometrically on proper, geodesically complete CAT$(0)$-spaces) and their quotients (CAT$(0)$-orbispaces). We describe some splitting and collapsing phenomena, explaining precisely how these action can degenerate to a possibly non-discrete limit action. Finally, we

Undirected Cat-and-Mouse is P-complete [PDF]

arXiv, 2015
Cat-and-mouse is a two-player game on a finite graph. Chandra and Stockmeyer showed cat-and-mouse is P-complete on directed graphs. We show cat-and-mouse is P-complete on undirected graphs. To our knowledge, no proof of the directed case was ever published. To fill this gap we give a proof for directed graphs and extend it to undirected graphs.

Structures of α‐galactosaminidases from the CAZy GH114 family and homologs defining a new GH191 family of glycosidases

Acta Crystallographica Section D, EarlyView.
Structural and functional analysis of a new fungal GH114 endo‐α‐1,4‐galactosaminidase, along with homologs that establish a new GH191 family of glycoside hydrolases, are reported. In addition, various crystal pathologies led to the development of a new refinement procedure for disordered structures.Endo‐galactosaminidases are an underexplored family of

$R\text{-}\mathrm{Mod}$-enriched categories are left $\underline{R}$-module objects of $Cat(\mathbb{A}\mathrm{b})$ and $Cat(\mathbb{A}\mathrm{b})$-enriched functors [PDF]

arXiv
We establish the feasibility of investigating the theory of $R\text{-}\mathrm{Mod}$-enriched categories, for any commutative and unitary ring $R$, through the framework of $\mathbb{A}\mathrm{b}$-enriched category theory. In particular, we prove that the category of $R$-$\mathrm{Mod}$-enriched categories, $Cat(R$-$\mathrm{Mod})$, the category of ...

Can we explain managerial non‐answers during conference call Q&As?

Contemporary Accounting Research, EarlyView.
Abstract Management teams often avoid answering questions during conference call question and answer sessions (Q&As). Viewing this as an information asymmetry issue, accounting scholars have suggested that this behavior is ill‐advised and that non‐answers signal to investors the suppression of bad news.

A Xanthine Derivative With Novel Heat Shock Protein 90‐Alpha Inhibitory and Senolytic Properties

Aging Cell, EarlyView.
This study aimed to find safe senolytic drugs that selectively eliminate senescent cells. Focusing on HSP90 inhibitors, we employed a virtual screening to identify novel, safer compounds (A). K5, a xanthinic candidate, effectively eliminated senescent cells in various cellular models (B), extended lifespan in flies, and reduced aging signs in mice (C).

High‐throughput screen identifies MAS9 as a novel inhibitor of the C‐type lectin receptor‐2 (CLEC‐2)–podoplanin interaction

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose The C‐type lectin‐like receptor‐2 (CLEC‐2) is a platelet receptor for the endogenous ligand podoplanin. This interaction contributes to several (patho)physiological processes, such as lymphangiogenesis, preservation of blood and lymphatic vessel integrity organ development, and tumour metastasis.
