Firm Productivity and Exit During Economic Crisis: Does Market Potential Foster Resilience?
ABSTRACT This paper examines the relationship between firm productivity, market potential, and firm exit over the economic cycle, focusing on the COVID‐19 crisis. Using Spanish firm‐level data (2011–2022), we analyse how market potential shapes the link between productivity and survival.

WHAT ONCE WAS SHALL BE AGAIN: PALAEOLITHIC BIFACES AT THE NEOLITHIC SITE OF GIV'AT RABI EAST
Summary Giv'at Rabi East is a Pre‐Pottery Neolithic B site located in northern Israel, interpreted as a flint workshop. One area has been spatially identified as a ‘biface locality’; it is characterized by the presence of finished axes and preforms alongside débitage. Interestingly, Acheulean bifaces have also been recovered from this area.

A Stable Formulation for Wave‐Induced Fracture in Peridynamics
ABSTRACT The bond‐associated quadrature point formulation is a very accurate peridynamic formulation for elasticity, but modeling fracture by the traditional deletion of bonds can trigger severe numerical instabilities. These instabilities are most pronounced for wave‐induced fracture, where stress waves continue to propagate through already damaged ...

Abstract Spatial heterogeneity, manifested as strong variability in hydraulic conductivity (K) within geological formations, exerts a fundamental control on groundwater flow and solute transport. Because K can vary over multiple orders of magnitude in complex three‐dimensional patterns, predicting contaminant plume migration remains a long‐standing ...

Alkoxy side chains regulate hydrazone‐linked COF nanochannel microenvironments by tuning pore polarity, reactant adsorption, and charge‐separation behavior. The optimized framework facilitates oxygen activation and hydrogen peroxide photosynthesis in real water and a 1 L natural‐sunlight reactor. LCA further shows that natural sunlight and larger‐scale

Tensor‐Train Compression of a Volume Integral Eddy Current Problem in Discontinuous Galerkin
ABSTRACT The paper presents a low‐rank tensor compression strategy based on the tensor‐train (TT) format for the integral operator arising in eddy current problems. Unlike classical matrix compression techniques such as the fast multipole method (FMM) or hierarchical matrices (ℋ$$ \mathscr{H} $$‐matrices), which typically compress only far‐field ...

Mechanistic Insights Into Zn‐Promoted CO2 Electroreduction on α‐CuZn Alloys in Aprotic Media
Elucidating nonaqueous CO2 reduction: Zinc boosts copper activity by tuning surface interactions for improved CO2 activation. How Zn enhances the performance of Cu electrocatalysts for CO2${\mathrm{CO}}_{2}$RR in nonaqueous electrolytes remains an open question.

Multiple Solutions of a Nonlocal Problem with Nonlinear Boundary Conditions
In this article, we consider a class of nonlocal p(x)-Laplace equations with nonlinear boundary conditions. When the nonlinear boundary involves critical exponents, using the concentration compactness principle, mountain pass lemma, and fountain theorem,
