WS2 Micro‐Dome Single Photon Source in a Tunable Open Cavity

Advanced Optical Materials, EarlyView.
In this work, a single‐photon source based on WS2 micro‐domes is realized and integrated into an open, tunable optical microcavity. Single‐photon emission from the coupled emitter–cavity system is observed. Detailed analysis shows that a pronounced acoustic phonon emission sideband contributes specifically to the non‐resonant emitter–cavity coupling in

Strict Avalanche Criterion of SHA-256 and Sub-Function-Removed Variants

Cryptography
The measure of diffusion, the property of dissipating patterns and statistical structures in cryptographic transformations, serves as a valuable heuristic for assessing the obscurity of patterns that could lead to collisions.

Snow variability effect upon avalanching

Ice and Snow, 2015
Thickness, density, shearing strength, and temperature of snow on mountain slopes are considered as stochastic fields or processes. Parameters of these fields (processes) were estimated in several geographical regions. Errors of snow stability estimation are shown to be depending on the above parameters, quantity of point measurements, and the ...

Interacting Parallel Fluidic Hysterons

Advanced Science, EarlyView.
The parallel coupling of fluidic hysterons is introduced, establishing advanced functionalities in inflatable soft systems. A pressure–volume framework reveals how preset volumes Δv∗${\Delta }v^*$ tune nonlinear interactions between hysterons and actuation sequences without changing architecture. Experiments validate the predictions, opening new routes
