Willis coupling, also known as pressure-velocity cross in acoustic materials has received much attention the past years. This effect been found useful metasurface designs for wave redirection. We find that coupling phononic crystals provides rich physics to manipulate waves. Here, we report extreme asymmetric lateral sound beaming a two-dimensional crystal composed of scatterers. By matching se...

Coupling of the previously characterized beta1- and beta2-like adrenoceptors in the sea pansy Renilla koellikeri with adenylate cyclase was examined in membrane preparations from this cnidarian. Adenylate cyclase activity was stimulated by several guanine nucleotides, such as GTP, Gpp(NH)p and GTPgammaS. Fluoride ions and cholera toxin greatly enhanced the enzyme activity, whereas forskolin had...

We examine diierent possibilities of coupling saturation-based theorem pro-vers by exchanging positive/negative information. We discuss which positive or negative information is well-suited for cooperative theorem proving and show in an abstract way how this information can be used. Based on this study, we introduce a basic model for cooperative theorem proving. We present theoretical results r...

We demonstrate a novel platform to control the thermo-optic sensitivity in nanophotonic devices by evanescent coupling of light with bimaterial cantilevers. The cantilever can be designed to provide a negative thermal feedback to passively compensate for the positive thermo-optic effect in the waveguide core. We demonstrate athermal operation over 14 deg in cantilever coupled Silicon ring reson...

molecular dynamics simulation has been performed to analyze the effect of the presence of gold nanoparticle on dynamics of kob-anderson binary lennard-jones (blj) mixture upon supercooling within the framework of the mode coupling theory of the dynamic glass transition. the presence of gold nanoparticle has a direct effect on the liquid structure and causes the peaks of the radial distribution ...
