Filament attachment dynamics in actin-based propulsion
J. I. Katz, A. E. Carlsson
Theory and experiment have established that F-actin filaments are strongly attached to the intracellular parasites (such as Listeria) they propel with ``comet tails''. We consider…
Low Frequency Radio Pulses from Gamma-Ray Bursts?
Vladimir V. Usov, Jonathan I. Katz
Gamma-ray bursts, if they are generated in the process of interaction between relativistic strongly magnetized winds and an ambient medium, may be accompanied by very short pulses…
Compton Electrons and Electromagnetic Pulse in Supernovae and Gamma-Ray Bursts
J. I. Katz
When gamma-rays emerge from a central source they may undergo Compton scattering in surrounding matter. The resulting Compton-scattered electrons radiate. Coherent radiation by suc…
A Cubic Micron of Equilibrium Pair Plasma?
J. I. Katz
Is it possible to create a small volume of equilibrium pair plasma in the laboratory with an intense laser pulse? No. The required power would exceed 10^{18} W. The number of seed…
After HETE
J. I. Katz
The outstanding task of gamma-ray burst astronomy is to test the hypothesis that they are at cosmological distances. This can be done by determining the coordinates of at least a f…
Statistics and Microphysics of the Fracture of Glass
J. I. Katz
The tensile strength of fused silica fibers is believed to approach its intrinsic value at low temperature, and modern experiments indicate very small, perhaps unmeasured, intrinsi…
