Asymptotics of work distributions: the pre-exponential factor [PDF]
The European Physical Journal B, 2011 We determine the complete asymptotic behaviour of the work distribution in driven stochastic systems described by Langevin equations. Special emphasis is put on the calculation of the pre-exponential factor which makes the result free of adjustable parameters.

Theory of the Pre-exponential Factor in Organic Semiconductors [PDF]
The Journal of Chemical Physics, 1970 Tunneling through intermolecular barriers from activated energy levels of molecules is postulated to be the conduction mechanism in some organic semiconductors. The compensation rule follows immediately from this model. The relationship between the characteristic temperature on one hand, and the barrier shape, height, width, and the effective mass of ...

Thermal Degradation of Vegetable Oils
Foods, 2023 Vegetable oils provide lipids and nutrition and provide foods with a desirable flavor, color, and crispy texture when used to prepare fried foods. However, the oil quality is degraded at elevated temperatures, and thus must be examined frequently because

Rheological behavior of rosin-sourced anhydride bio-epoxy resin system
Journal of Aeronautical Materials, 2021 Viscosity is the main rheology parameter of thermosetting resin matrix processing, which is an important factor effecting processing performance. The viscosity-temperature curves at dynamic states and viscosity-time curves at stead state were measured by
