We investigate stochastic models for the lay-down of flexible fibers on a moving conveyor belt for the case of small stochasticity and small belt velocity. Using a suitable scaling we obtain a ...

We solve the one-dimensional Fokker-Planck equation for radiation belt electrons under the assumption of the conservation of the first and second adiabatic invariants (so-called radial diffusion). We ...

(Nanowerk News) All the objects around us emit thermal radiation. Usually, this radiation can be described very accurately using Planck’s law. If, however, the radiating object is smaller than the ...

Planck’s constant is one of the most important numbers in science. It describes the relationship between the energy and frequency of an electromagnetic wave in an equation known as the Planck-Einstein ...
