This article applauds the declaration of 2005 as the International Year of Physics by the United Nations General Assembly, and hopes that the observance will help all concerned to explore ways of shifting the physics ...

We analyze the properties and stability of two-color discrete localized modes in arrays of channel waveguides where tunable quadratic nonlinearity is introduced as a nonlinear defect by periodic poling of a single waveguide ...

We discuss a nonhomogeneous population of pulsatil integrate-and-fire neural oscillators, coupled through purely inhibitory synapses. For instantaneous communication, we provide a strategy to generate synaptic couplings ...

Hydrostatic studies fluids at rest. Fluids have characteristic properties such as surface tension, density, specific gravity and viscosity.

It is shown that in a current-carrying cylindrical plasma with a free boundary, viscosity and thermal conductivity can lead to large scale steady convection. The physical situation is identical to the case when the plasma ...

Physical exercise has frequently been the target of research studies related to the treatment of Alzheimer's disease. The level and routine of physical exercise can influence the progression of the disease, as well as ...
