We study the excitation of spin waves in magnetic insulators by the current-induced spin-transfer torque. We predict preferential excitation of surface spin waves induced by an easy-axis surface anisotropy with critical current inversely proportional to the penetration depth and surface anisotropy. The surface modes strongly reduce the critical current and enhance the excitation power of the cu...

in the present paper axial distributions of plasma and floating potentials, electron and iondensities and eedf have been measured in the dl region of a hg discharge constriction. an attempt hasbeen made for the resolution of opposing charged layer structures in dl. excitation processes in theconstriction region are studied. using the linearization method for the nonstationary balance equationss...

No severe or prolonged bodily illness followed this incident in the red-room; it only gave my nerves a shock; of which I feel the reverberation to this day...Next day, by noon I was up and dressed, and sat wrapped in a shawl by the nursery hearth. I felt physically weak and broken down; but my worst ailment was an unutterable wretchedness of mind: a wretchedness which kept drawing from me silen...

We study the time evolution of expectation value Wilson loop as a non-local observable in strongly coupled field theory with critical point at finite temperature and nonzero chemical potential, which is dual to an asymptotically AdS charged black hole via gauge/gravity duality. Due inject energy into plasma, potential increase values plasma experiences out-of-equilibrium process. By defining me...

It is often anticipated that two-photon excitation (TPE) laser scanning microscopy should improve cell survival and tissue penetration relative to conventional one-photon excitation (OPE) confocal scanning laser microscopy (CLSM). However few studies have directly compared live cell imaging using one- vs two-photon laser scanning microscopy. We have used calcein-loaded in situ chondrocytes with...

BACKGROUND Duration and speed of propagation of the pulse are essential factors for stability of excitation waves. We explore the propagation of excitation waves resulting from periodic stimulation of an excitable cable to determine the minimal stable pulse duration in a rate-dependent modification of a Chernyak-Starobin-Cohen reaction-diffusion model. RESULTS Various pacing rate dependent fe...
