High-temperature ratchets with sawtooth potentials
Physical Review E, 2016The concept of the effective potential is suggested as an efficient instrument to get a uniform analytical description of stochastic high-temperature on-off flashing and rocking ratchets. The analytical representation for the average particle velocity, obtained within this technique, allows description of ratchets with sharp potentials (and potentials ...

Percolation temperature and the ‘‘instability’’ of the effective potential
Physical Review D, 1985We show that in spontaneously broken lambdaphi/sup 4/ theory the percolation temperature coincides with the temperature at which the semiclassical (loop) expansion of the effective potential (free energy) of the system around a uniform field configuration fails. This allows us to extract the percolation temperature directly from the effective potential.

Effect of Temperature on the Equilibrium Endplate Potential
Nature, 1972IT has been suggested1 that during the interaction of acetylcholine (ACh) with the cholinergic receptor (ChR) each elementary ionic channel of the postsynaptic membrane (PSM) becomes active, that is accessible for K+ and Na+ ions, for such short a time that the equilibrium potential (Ep) of PSM is determined by a current which is far from stationary ...

Effect of Temperature on PV Potential in the World
Environmental Science & Technology, 2011This work aims to identify the geographic distribution of photovoltaic (PV) energy potential considering the effect of temperature on PV system performance. A simple framework is developed that uses the JIS C 8907 Japanese industrial standard to evaluate the effects of irradiation and temperature on PV potential.

The temperature acclimation potential of tropical bryophytes
Plant Biology, 2013AbstractBryophyte biomass and diversity in tropical moist forests decrease dramatically from higher altitudes towards the lowlands. High respiratory carbon losses at high temperatures may partly explain this pattern, if montane species are unable to acclimatise their metabolic rates to lowland temperatures.

Temperature and potential temperature beneath island arcs
Tectonophysics, 1970Abstract Potential temperature within a convecting fluid is a useful concept if the distance which heat diffuses in the time taken for the material to overturn is appreciably smaller than the scale height. This condition is satisfied within the mantle, and therefore the equation governing the conservation of energy may be simplified by using ...

Bonn potential model at finite temperature
Physical Review C, 1996By using the thermofield dynamics, we have calculated the effective coupling of nucleon-nucleon mesons by summing the three-lines vertices and the masses of nucleon and mesons by summing the corresponding self-energy diagrams of the Bonn potential model at finite temperature.

Atmospheric Stability and Potential Temperature
2021The culmination of the implications of the Ideal Gas Law, hydrostatic balance, and humidity leads naturally to an ability to describe the path of a hypothetical blob of air—called an air parcel—as it is forced to rise in the atmosphere. This tendency to rise is a measure of atmospheric stability.

Potential Temperature and the Stratosphere
Nature, 1931THE high coefficients of correlation between the measures of certain meteorological elements at the tropopause and the air-pressure at 9 kilometres cited by L. H. G. Dines in his letter in NATURE of May 30 may be welcomed as a reminder of the intricate but regular associations of the meteorological elements in the sequence of weather-changes which are ...

The actions of interferon are potentiated at elevated temperature
Nature, 1978INTERFERON was discovered1 because of its antiviral properties, but interferon preparations have other biological activities. These include inhibition of transplanted tumours in vivo2 and of cell multiplication in vitro3,4, as well as regulatory roles in the immune response5.
