Microscopic Eye Movements Compensate for Nonhomogeneous Vision within the Fovea

Humans rely on the fovea, the small region of the retina where receptors are most densely packed, for seeing fine spatial detail. Outside the fovea, it is well established that a variety of visual functions progressively decline with eccentricity. In contrast, little is known about how vision varies within the central fovea, as incessant microscopic eye movements prevent isolation of adjacent f...

Microscopic dynamics in the liquid Li-Na alloy: an ab initio molecular dynamics study.

We present results for several structural and dynamical properties of the liquid Li(1-x)Na(x) alloy. The study has been carried out by means of the orbital-free ab initio molecular dynamics method, combined with local ionic pseudopotentials constructed within the same framework. We obtain good agreement with the available experimental data, reproducing accurately, the strong homocoordinating te...

A ug 1 99 8 Microscopic calculation of 6 Li elastic and transition form factors

Variational Monte Carlo wave functions, obtained from a realistic Hamilto-nian consisting of the Argonne v 18 two-nucleon and Urbana-IX three-nucleon interactions, are used to calculate the 6 Li ground-state longitudinal and transverse form factors as well as transition form factors to the first four excited states. The charge and current operators include one-and two-body components , leading ...

Electrochemical and electron microscopic characterization of Super-P based cathodes for Li–O2 batteries

Aprotic rechargeable Li-O2 batteries are currently receiving considerable interest because they can possibly offer significantly higher energy densities than conventional Li-ion batteries. The electrochemical behavior of Li-O2 batteries containing bis(trifluoromethane)sulfonimide lithium salt (LiTFSI)/tetraglyme electrolyte were investigated by galvanostatic cycling and electrochemical impedanc...
