International Year of Physics
(Daily Express, 2005-03)
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 ...
Two-color discrete localized modes and resonant scattering in arrays of nonlinear quadratic optical waveguides
(2005)
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 ...
Firing sequence storage using inhibitory synapses in networks of pulsatil nonhomogeneous integrate-and-fire neural oscillators
(2002)
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 ...
Stationary convection in a cylindrical plasma
(1994)
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 ...
Structure of liquid GeO2 from a computer simulation model
(2004)
The structural properties of liquid GeO2 were investigated using molecular dynamics simulation. A comparison of the obtained pair correlation functions, coordination number, angular distribution, and both the neutron and ...
Physical Exercise and Its Effects on Alzheimer's Disease
(2017-01-04)
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 ...
The physical status of a selected population

Physical activity, physical condition and quality of life in schoolchildren
(Research Group on Physical Activity and Sports Sciences (GICAFD), 2021)
The study analyses the physical condition and quality of life on the physical activity of schoolchildren in a Peruvian educational institution, applying a non-probability and convenience sampling, to 168 first-year high ...
Circularly polarized alfven and ion cyclotron waves in space plasmas
(1995)
The linear and nonlinear theory of circularly-polarized Alfvdn and ion-cyclotron waves in multicomponent plasmas is reviewed. It is shown that minor heavy- ion components play an important role in the dispersive properties ...
Simplified calculations for radiation reaction forces
(1974)
The Lorentz-Dirac equation of motion for the electron is derived by a new method which makes tedious power series expansions unnecessary. Copyright © 1975 American Institute of Physics.
