The e ciency of the latter processes depends on the temperature T : we expect it to increase as T is increased. At very low temperatures the dominant scattering is elastic, and then τ does not depend strongly on temperature but instead it depends on the amount of disorder (realized as random static impurities). We expect τ to decrease as the temperature or the amount of disorder in the system a...

Ab&act-The dispersion relation for wave propagation in a homogeneous, electrically neutral electron gas subject to crossed static electric and magnetic fields is derived using the coupled Maxwell-Boltzmann-Vlasov equations. The cutoff condition for transverse circularly polarized electromagnetic waves is obtained from the derived dispersion relation. The variation of the cutoff frequency CO,, w...

The stress-strain relations and the yield behavior of a model glass (a 80:20 binary Lennard-Jones mixture) is studied by means of molecular dynamics simulations. In a previous paper it was shown that, at temperatures below the glass transition temperature, Tg, the model exhibits shear banding under imposed shear. It was also suggested that this behavior is closely related to the existence of a ...

Tapio Schneider Atmospheric and Oceanic Sciences Program, Princeton University Isaac M. Held Geophysical Fluid Dynamics Laboratory, NOAA Introduction. The static stability @z  and the meridional gradient @y  of the longitudinally averaged potential temperature  both play prominent roles in theories for baroclinic eddy uxes (Stone 1972; Green 1970). Despite much ongoing work, there is still n...

New terms are derived for the three-dimensional effective action of the static modes of pure gauge SU(N) at high temperature. In previous works, effective vertices have been obtained by evaluating diagrams involving 2, 3 or 4 external static gluons with one internal nonstatic loop. I take a somewhat different approach by making a covariant derivative expansion of the one loop effective action f...

We study the Chern-Simons number diffusion rate in the (1+1)-dimensional lattice Abelian Higgs model at temperatures much higher than, as well as comparable to, the sphaleron energy. It is found that in the high-temperature limit the rate is likely to grow as power 2/3 of the temperature. In the intermediate-temperature regime, our numerical simulations show that very weak temperature dependenc...

Small alterations in static magnetic fields have been shown to affect certain chemical reaction rates ex vivo. In this manuscript, we present data demonstrating that similar small changes in static magnetic fields between individual cell culture incubators results in significantly altered cell cycle rates for multiple cancer-derived cell lines. This change as assessed by cell number is not a re...

introduction: one of the main sections of warm up is stretching which the importance of them is static and dynamic stretching. the purpose of this study was to examine the effects of static and dynamic stretching within a pre-exercise warm-up on the static and dynamic in soccer players. materials and methods: eighteen physical education female students (height: 159.68 ± 5.94 cm; mass: 60.21 ± 5...

This paper is an attempt to determine quasi-static thermal stresses in a thin elliptical plate which is subjected to transient temperature on the top face with zero temperature on the lower face and the homogeneous boundary condition of the third kind on the fixed elliptical curved surface. The solution to conductivity equation is elucidated by employing a classical method. The solution of stre...
