We revisit the dynamics of the curvaton in detail taking account of effects from thermal environment, effective potential and decay/dissipation rate for general field values and couplings. We also consider the curvature perturbation generated through combinations of various effects: large scale modulation of the oscillation epoch, the effective dissipation rate and the timing at which the equat...

Accreting black holes radiate in one of several spectral states, switching from one to another for reasons that are as yet not understood. Using the best studied example, Cyg X-1, we identify the geometry and physical conditions characterizing these states. In particular, we show that in the hard state most of the accretion energy is dissipated in a corona-like structure which fills the inner f...

persistence of benthiocarb in soil as affected by uv and sunlight exposure was studied. treated soil was placed in petri plate, brought to field capacity moisture and then exposed to uv and sunlight. residues of benthiocarb in soil dissipated with half lives of 2.10, 11.85 and 43.63 days under uv, sunlight and dark condition, respectively. soil samples kept under dark showed the slowest dissipa...

Piezoelectric transducer (PZT) patches can be attached to structures in order to reduce vibration. The PZT patches essentially convert vibrational mechanical energy to electrical energy. The electrical energy can be dissipated via an electrical impedance. This paper introduces a method of implementing an arbitrary impedance using a current source and digital signal processor (DSP). The \synthet...

According to the International Technology Roadmap for Semiconductors in the next 10-15 years the limits imposed by the physics of switch operation will be the major roadblock for future scaling of the CMOS technology. Among these limits the most fundamental is represented by the so-called Shannon-von Neumann-Landauer limit that sets a lower bound to the minimum heat dissipated per bit erasing o...

ATP-hydrolysis is the basic energy source of many physiological processes, but there is a lack of knowledge regarding its biological role other than energy transfer and thermogenesis. Not all the energy released by ATP-hydrolysis could be used in powering target biological processes and functions. Partial energy dissipates into water. By validating the impact of this dissipated energy, we found...

A friction energy formalism is considered and adapted to formalize the fretting wear responses of adhesive wear and non-adhesive wear interfaces. It is shown that for non-adhesive wear tribocouples like hard coatings (TiN, TiC, etc.) the wear kinetics can be formalized using the accumulated friction dissipated energy. By contrast, adhesive wear contacts involving aluminium and titanium alloys d...
