Anomalous dissipation of energy in three dimensional turbulence is one of the basic statements of physical theory [55]. It has been verified experimentally to a large degree [75], but not mathematically. The statement is about the average behavior of the energy dissipation rate = ν〈|∇u|〉 as ν → 0. Here ν is kinematic viscosity, u is the velocity (assumed to have mean zero), ∇ are spatial gradie...

The combined effect of a dissipative fluid and quintessence energy can simultaneously drive an accelerated expansion phase at the present time and solve the coincidence problem of our current Universe. A solution compatible with the observed cosmic acceleration is succinctly presented.

In urban rivers, groups of large waves are generated when boats like tankers pass. These waves are the main cause of reed covered bank erosion. Reed banks are required in order to protect the riverbank and to provide inhabitant for wildlife. Therefore it is important to clarify a relationship between wave energy and rate of bank erosion. For this purpose, we constructed detached breakwaters in ...

Molecular motors are nonequilibrium open systems that convert chemical energy to mechanical work. Here we investigate the nonequilibrium energetics of a single molecule kinesin by measuring the motion of an attached probe particle and its response to external forces with optical tweezers. The sum of the heat dissipation estimated from the violation of the fluctuation-response relation and the o...

Two well known, biologically inspired non-dynamical models of stochastic resonance, the threshold-crossing model and the fluctuating rate model, are analyzed in terms of channel information capacity and dissipation of energy necessary for small-signal transduction. Using analogies to spike propagation in neurons we postulate the average output pulse rate as a measure of dissipation. The dissipa...

In recent years, destructive earthquakes have shown the deficiencies of the existing buildings. One of the most effective mechanisms for dissipating the earthquake energy is inelastic deformation of the steel components. The objective of this research is to study the application of metallic dampers for dissipation of the earthquake energy and to investigate the behavior of concrete structures i...

Clark, Tau Technologies, Albuquerque, NM USA Robert Rubinstein, NASA Langley Research Center, Hampton, VA USA Abstract The response of the small scales of isotropic turbulence to periodic large scale forcing is studied using two-point closures. The frequency response of the turbulent kinetic energy and dissipation rat...

We have identified outflows and bubbles in the Taurus molecular cloud based on the ∼100 deg Five College Radio Astronomy Observatory CO(1-0) and CO(1-0) maps and the Spitzer young stellar object catalogs. In the main 44 deg area of Taurus, we found 55 outflows, of which 31 were previously unknown. We also found 37 bubbles in the entire 100 deg area of Taurus, none of which had been found previo...
