Accelerated algorithm for calculating spectra of aperiodic gratings

Компьютерная оптика
To compute the spectrum of aperiodic Bragg gratings, we address a direct scattering problem for the Helmholtz equation. Numerically, this problem necessitates the calculation of transfer matrix products, which involves multiple multiplications of matrix ...

The Role of Tip Charges in Dendrite Growth on Lithium Electrodes

ChemElectroChem, Volume 13, Issue 16, 18 August 2026.
During lithium deposition the lithium electrode is negatively charged. The negative charge accumulates at tips and attracts lithium cations, favoring dendrite growth. On metal electrodes, excess charges accumulate on protrusions and dendrites and induce local dipole potentials, which affect the deposition of ions.

A Multimodal Magnetically Driven Soft Robot With Integrated Actuation‐Sensing Based on Photothermal Reprogramming Technology

Advanced Science, Volume 13, Issue 46, 17 August 2026.
This work reports a thermally safe, photothermally reprogrammable magnetic soft robot with its reprogramming temperature tuned to ∼39.5°C for biocompatibility. It achieves multimodal locomotion (max speed of 1.8 BL/s) and integrates liquid‐metal capacitive sensing to monitor self‐motion and detect environmental changes in simulated gastric environments,

Aperiodic EEG and 7T MRSI evidence for maturation of E/I balance supporting the development of working memory through adolescence

Developmental Cognitive Neuroscience
Adolescence has been hypothesized to be a critical period for the development of human association cortex and higher-order cognition. A defining feature of critical period development is a shift in the excitation: inhibition (E/I) balance of neural ...
