Spectrally Adjustable Narrowband Photonic Device Based on Heat‐Driven Amorphous‐to‐Crystal Transformation of Si

Advanced Photonics Research, EarlyView.
The change in the dielectric function from the heat‐driven amorphous‐to‐crystal Si transformation can be used to engineer large spectral adjustability of Si‐based multilayered narrowband photonic devices operating in the IR region. This effect can be utilized to accurately adjust the resonance wavelength of fabricated amorphous multilayered structures ...

Geometrically Confined Strain Engineering of MoS2 via Quasi‐Van Der Waals Recrystallization of Gold Nanopillars

Advanced Science, EarlyView.
Geometrically confined quasi‐van der Waals (qvdW) recrystallization of patterned gold induces localized tensile strain in monolayer MoS2, enhancing its optoelectronic performance. The strain, induced during annealing after hBN encapsulation, leads to a 65‐fold increase in photoluminescence and a two‐order magnitude boost in mobility, offering a ...

Another Characteristic Property of the Cauchy Distribution [PDF]

The Annals of Mathematical Statistics, 1966
1. Main result. The purpose of this paper is to prove the theorem and corollary stated in this section. The corollary answers the question raised in Section 3 of [4] to which we also refer the reader for further motivation. THEOREM. Let X be a symmetric r.v., and Xi, i = 1, 2, , r.v.'s independently and identically distributed as X. The two conditions:

A Programmable, 3D Neuron‐On‐Chip Platform Integrating Near Real‐Time Biosensing and Multiaxial Loading for Mechanobiological Injury Profiling

Advanced Science, EarlyView.
A programmable 3D Neuron‐Injury‐on‐a‐Chip platform integrates multiaxial mechanical loading with ultrasensitive electrochemical biosensing to decode neuronal responses in real time. By mimicking physiologically relevant extension–torsion forces, the system reveals load‐specific biomarker trajectories (T‐Tau, NFL), gene regulation, and apoptosis.

Pre‐Torsion Tubular Metamaterials: Multi‐Effect Integration for Advanced Functional Applications

Advanced Science, EarlyView.
Through a pre‐torsion design paradigm, the authors design and fabricate a class of multi‐effect mechanical metamaterial that synergistically integrates compression‐torsion and auxetic behaviors over an extensive strain range, and their formation mechanisms are quantitatively analyzed and elucidated via experiments and finite element methods.
