Determining atmospheric electric fields using MGMR3D

Determining Progression in Glaucoma Using Visual Fields

The standardized visual field assessment, which measures visual function in 76 locations of the central visual area, is an important diagnostic tool in the treatment of the eye disease glaucoma. It helps determine whether the disease is stable or progressing towards blindness, with important implications for treatment. Automatic techniques to classify patients based on this assessment have had ...

Drop manipulation and surgery using electric fields.

We study the dynamics of a slender drop sandwiched between two electrodes using lubrication theory. A coupled system of evolution equations for the film thickness and interfacial charge density is derived and simplified for the case of a highly conducting fluid. The contact line singularity is relieved by postulating the existence of a wetting precursor film, which is stabilised by intermolecul...

Electric and Magnetic Fields

California Electric and Magnetic Fields Program A Project of the California Department of Health Services and the Public Health Institute INTRODUCTION Our daily use of electricity is taken for granted, yet scientific and public concern has arisen about possible health effects from electric and magnetic fields (EMF) that are created by the use of electricity. Because of this concern, the Califor...

Effects of atmospheric electric fields on detection of ultrahigh-energy cosmic rays

We show that atmospheric electric fields may affect the cosmic ray observations in several ways and may lead to an overestimation of the cosmic ray energies. The electric field in thunderclouds can be as high as a few kV/cm. This field can accelerate the shower electrons and can feed some additional energy into the shower. Therefore, ground array observations in certain weather conditions may o...
