Energy Landscapes in Chemical Reactions and Transport

ChemPhysChem, Volume 26, Issue 6, March 15, 2025.
Kinetics/dynamics of chemical reactivity and transport of chemical species in a solid are both determined by the energy landscape in which they take place. Discussing common grounds but also distinct differences may help in advancing the understanding in both fields.

TopoMAS: Large Language Model Driven Topological Materials Multi‐Agent System

Materials Genome Engineering Advances, EarlyView.
TopoMAS is an interactive multi‐agent framework that revolutionizes topological materials discovery through human–AI collaborative intelligence. The system integrates natural language processing, knowledge retrieval from literature and databases, crystal structure generation, and automated first‐principles calculations within a unified workflow.

Framework for canonical quantum plasmonics for finite structure in three dimensions [PDF]

EPJ Web of Conferences
We provide the framework and the tools for canonical quantization of plasmon polaritons from metallic or dielectric finite nanostructures. They allow one to diagonalize the Hamiltonian and to exactly determine the quantized electromagnetic field and an ...

Supersymmetric backgrounds in (1 + 1) dimensions and inhomogeneous field theory

Journal of High Energy Physics, 2023
We find a (1 + 1)-dimensional metric solution for a background hosting various supersymmetric field theories with a single non-chiral real supercharge. This supersymmetric background is globally hyperbolic even though it contains a naked null singularity.

Equivariant toric geometry and Euler–Maclaurin formulae

Communications on Pure and Applied Mathematics, Volume 79, Issue 3, Page 451-557, March 2026.
Abstract We first investigate torus‐equivariant motivic characteristic classes of toric varieties, and then apply them via the equivariant Riemann–Roch formalism to prove very general Euler–Maclaurin‐type formulae for full‐dimensional simple lattice polytopes.

Explaining the Comprehension–Production Vocabulary Gap Through Neural Networks and Cross‐Syndrome Evidence: Insights From Williams Syndrome

Developmental Science, Volume 29, Issue 2, March 2026.
ABSTRACT The comprehension–production vocabulary gap is a well‐documented hallmark of language development; however, anecdotal evidence suggests that this asymmetry may be reduced in children with Williams syndrome (WS). Here, we use empirical data to characterise the comprehension–production gap and computational modelling to investigate potential ...

APPROXIMATE CANONICAL QUANTIZATION FOR COSMOLOGICAL MODELS [PDF]

International Journal of Modern Physics D, 1999
In cosmology minisuperspace models are described by nonlinear time-reparametrization invariant systems with a finite number of degrees of freedom. Often these models are not explicitly integrable and cannot be quantized exactly. Having this in mind, we present a scheme for the (approximate) quantization of perturbed, nonintegrable, time ...

Securing the Unseen: A Comprehensive Exploration Review of AI‐Powered Models for Zero‐Day Attack Detection

Expert Systems, Volume 43, Issue 3, March 2026.
ABSTRACT Zero‐day exploits remain challenging to detect because they often appear in unknown distributions of signatures and rules. The article entails a systematic review and cross‐sectional synthesis of four fundamental model families for identifying zero‐day intrusions, namely, convolutional neural networks (CNN), deep neural networks (DNN ...

Wavepacket Evolution in Unimodular Quantum Cosmology

Galaxies, 2018
The unimodular theory of gravity admits a canonical quantization of minisuperspace models without the problem of time. We derive instead a kind of Schrödinger equation.

Metabolic reprogramming of efferocytosis in the tumour microenvironment: From apoptotic‐cell clearance to therapeutic targeting

Clinical and Translational Medicine, Volume 16, Issue 2, February 2026.
This review systematically deconstructs the pathological efferocytic—metabolic axis in tumours, framing it as a three‐stage, self‐reinforcing cycle: from metabolite‐driven macrophage recruitment, through hijacked surface recognition, to post‐phagocytic metabolic reprogramming that locks in immunosuppression.
