Monte-Carlo calculation of the lateral Casimir forces between rectangular gratings within the formalism of lattice quantum field theory
We propose a new Monte-Carlo method for calculation of the Casimir forces.
Our method is based on the formalism of noncompact lattice quantum
electrodynamics. This approach has been tested in the simplest case of two
ideal conducting planes. After this the method has been applied to the
calculation of the lateral Casimir forces between two ideal conducting
rectangular gratings. We compare our calculations with the results of PFA and
"Optimal" PFA methods.Comment: 12 pages, 6 figures, accepted in Int. J. Mod. Phys.
Existence and large time behavior for generalized Kelvin-Voigt equations governing nonhomogeneous and incompressible fluids
Generalized Kelvin-Voigt equations governing nonhomogeneous and incompressible
fluids are considered in this work. We assume that, in the momentum equation, the diffusion
and relaxation terms are described by two distinct power-laws. Moreover, we assume that the
momentum equation is perturbed by an extra term, which, depending on whether its signal is
positive or negative, may account for the presence of a source or a sink within the system. For
the associated initial-boundary value problem, we study the existence of weak solutions as well
as the large time behavior of the solutions.Portuguese Foundation for Science and Technology: UID/MAT/04561/2019info:eu-repo/semantics/publishedVersio
Outbreaks of Tularemia in a Boreal Forest Region Depends on Mosquito Prevalence
Background. We aimed to evaluate the potential association of mosquito prevalence in a boreal forest area with transmission of the bacterial disease tularemia to humans, and model the annual variation of disease using local weather data
