Perfect Matching Under Precedence Constraints

Networks, Volume 87, Issue 2, Page 175-190, March 2026.
ABSTRACT In this article, we motivate and define variants of perfect matching under precedence constraints where a perfect matching is built incrementally and precedence constraints ensure that an edge may only be added to the matching if the edge's predecessor vertices have already been covered.

AIMNet2‐NSE: A Transferable Reactive Neural Network Potential for Open‐Shell Chemistry

Angewandte Chemie, Volume 138, Issue 5, 28 January 2026.
AIMNet2‐NSE enables accurate modeling of open‐shell radical chemistry through neural spin‐charge equilibration (NSE). This machine learning interatomic potential predicts radical reaction energies, barriers, and spin‐crossing events with near‐DFT accuracy while offering five orders of magnitude computational speedup, making high‐throughput exploration ...

Lattice Strain and Piezoelectric Field Modulated Piezo‐Photocatalytic Nitrate‐to‐Ammonia Conversion in Chemically Bonded S‐Scheme Heterojunction

Advanced Science, Volume 13, Issue 7, 3 February 2026.
Under ultrasonic excitation, 5% compressive strain optimizes the ZnO@ZnSe heterojunction. The strain enhances H2O dissociation into active *H on Zn sites and NO3− adsorption on Se sites, facilitating their hydrogenation into NH4+ with optimal kinetics and thermodynamics. Abstract Piezo‐photocatalysis provides an efficient approach to harness mechanical

Limit Cycles of Continuous–Discontinuous Piecewise Linear Hamiltonian Systems in ℝ2 Separated by the Curve y=sinx

Mathematical Methods in the Applied Sciences, Volume 49, Issue 3, Page 2093-2097, February 2026.
ABSTRACT These last decades piecewise differential systems have been studied intensively, mainly due to their applications. Inside the study of the dynamics of these differential systems, the limit cycles, that is, the isolated periodic orbits inside the set of all periodic orbits of the system, play a main role.

Tracking Structural and Electron Spin Density Changes in a Cooperative Mn3+ Spin Crossover Complex at Atomic Scale via Low Temperature Solid‐State NMR

Angewandte Chemie, Volume 138, Issue 3, 16 January 2026.
The spin transition of a Mn(III) complex is investigated by tracking the evolution of the 1H and 13C NMR signals of individual sites under fast low‐temperature magic angle spinning conditions. The proposed experimental methodology combined with ab initio calculations of the paramagnetic NMR shifts provides a unique toolbox to study the electronic ...
