Designing Elastic Softening Under Compression via Dipole-Dipole Interactions: The Case of Na₂TiSiO₅. [PDF]

Small
Pressure usually stiffens solids, yet Na2TiSiO5 exhibits anomalous elastic softening under compression. Unlike conventional mechanisms driven by geometric rearrangements or electronic spin‐state transitions, the softening originates from enhanced dipole coupling along head‐to‐tail TiO5 chains.

SPICE‐Compatible Compact Modeling of Cuprate‐Based Memristors Across a Wide Temperature Range

Advanced Electronic Materials, EarlyView.
A physics‐guided compact model for YBCO memristors is introduced, incorporating carrier trapping, field‐induced detrapping, and a differential balance equation to describe their switching dynamics. The model is compared with experiments and implemented in LTspice, allowing realistic circuit‐level simulations.

A Unifying Approach to Self‐Organizing Systems Interacting via Conservation Laws

Advanced Intelligent Discovery, EarlyView.
The article develops a unified way to model and analyze self‐organizing systems whose interactions are constrained by conservation laws. It represents physical/biological/engineered networks as graphs and builds projection operators (from incidence/cycle structure) that enforce those constraints and decompose network variables into constrained versus ...

Incomplete climate‐driven peripatric speciation in Moehringia sect. Moehringia (Caryophyllaceae) in the European Alps

American Journal of Botany, EarlyView.
Abstract Premise The origin of endemic species in the European Alps is commonly attributed to the climatic oscillations of the Quaternary. Moehringia sect. Moehringia, with 12 of 15 species endemic to the Alps and mostly restricted to well‐known glacial refugia, is a prime system for investigating the diversification of a lineage originating in the ...
