Advanced Optical Materials, EarlyView.Whispering‐gallery‐mode microresonators with sharp resonant peaks enable photonic barcoding. Similar to a chameleon, a rare‐earth‐free microcavity with π‐conjugated PAHs enables visibleto‐near infrared color generation from a single microbead. The unique resonat emission (spectral barcode) can be dynamically transformed via excitation wavelength change,

The non-isothermal spreading of a thin drop on a heated or cooled horizontal substrate [PDF]
, 2005 We revisit the spreading of a thin drop of incompressible Newtonian fluid on a uniformly heated or cooled smooth planar surface. The dynamics of the moving contact line are modelled by a Tanner Law relating the contact angle to the speed of the contact ...

Nanocrystal Quality–Controlled Scintillation in Porous YAG:Ce Aerogels
Advanced Optical Materials, EarlyView.High‐temperature thermal treatment of YAG:Ce nanoscintillator aerogels increases light yield under ionizing radiation by up to eightfold without affecting timing performance. Additionally, low‐temperature atmospheric treatments reversibly modify the cerium oxidation state, revealing strong defect sensitivity and offering new strategies to optimize ...

Electronic Journal of Differential Equations, 2014 This article concerns the traveling wave solutions of nonlocal delay reaction-diffusion equations without local quasimonotonicity. The existence of traveling wave solutions is obtained by constructing upper-lower solutions and passing to a limit ...

Intermittent Motion, Nonlinear Diffusion Equation and Tsallis Formalism
Entropy, 2017 We investigate an intermittent process obtained from the combination of a nonlinear diffusion equation and pauses. We consider the porous media equation with reaction terms related to the rate of switching the particles from the diffusive mode to the ...

Dynamics of drop impact on solid surfaces: evolution of impact force and self-similar spreading
, 2017 We investigate the dynamics of drop impacts on dry solid surfaces. By synchronising high-speed photography with fast force sensing, we simultaneously measure the temporal evolution of the shape and impact force of impacting drops over a wide range of ...

Formation Control of Multi‐Agent System with Local Interaction and Artificial Potential Field
Advanced Robotics Research, EarlyView.This article proposes a local interaction‐based formation control method for Multi‐Agent system, integrating consensus and leader‐follower strategies with a stress response mechanism—artificial potential field to reduce communication overhead and enable obstacle avoidance. Experimental results on triangular, square, and hexagonal formations confirm its

Rumor Spreading Model Considering Individual Activity and Refutation Mechanism Simultaneously
IEEE Access, 2020 With the rapid development of social networks, an increasing number of factors will affect the spread of rumors. In this paper, we simultaneously consider individual activity differences and rumor-refuting nodes, and we propose a new multifactor model ...
