Microcapsule‐Mediated Vibration‐Induced Emission for Real‐Time Visualization of Polymer Deformation

Advanced Optical Materials, EarlyView.
A mechanochromic microcapsule is reported that combines vibration‐induced luminescence (VIE) with mechanically controlled release functionality. By embedding the microcapsules into a polymer matrix, the conformational changes of VIE molecules can be precisely amplified into visual fluorescent color signals, enabling real‐time, high‐sensitivity ...

Random Matrix Theory by the Supersymmetry Method Beyond the Sigma-Model

, 1997
The leading correction to the smoothed connected energy density-density correlation function is obtained for the large energy difference, within the context of the Gaussian Random Matrix Theory.

TreeSpider: In‐Canopy Exploration With Tether‐Based Aerial Modular Arms

Advanced Robotics Research, EarlyView.
A tethered drone with perching arms and a 360° ring enables unprecedented maneuverability within dense forest canopies. By dynamically adjusting tether length and decoupling pitch from the frame, it navigates between branches, senses multiple trees, and interacts physically with foliage.

Lagrangian Duality for Multiobjective Programming Problems in Lexicographic Order

Abstract and Applied Analysis, 2013
This paper deals with a constraint multiobjective programming problem and its dual problem in the lexicographic order. We establish some duality theorems and present several existence results of a Lagrange multiplier and a lexicographic saddle point ...

Strong Proton‐Phonon Coupling Drives Fast Ion Transport in Perovskites

Advanced Science, EarlyView.
Experimental and computational phonon analysis of ABO3‐type proton conductor BaSnO3 shows that substitution on the B‐site with yttrium forms an imaginary phonon mode which is instrumental for the function as proton conductor. This overcompensates the adverse proton trapping effect of the yttrium.
