What is Special about Diffusion on Scale-Free Nets?
Erik M. Bollt, Daniel ben-Avraham
We study diffusion (random walks) on recursive scale-free graphs, and contrast the results to similar studies in other analytically soluble media. This allows us to identify ways i…
Modulation of spin dynamics in a channel of a non-ballistic spin field effect transistor
Ehud Shafir, Min Shen, Semion Saikin
We have investigated the effect of the gate voltage on spin relaxation in an Al0.3Ga0.7As/GaAs/Al0.3Ga0.7As heterostructure. The study is motivated by a recent proposal for a non-b…
Nanosurgery: Observation of Peptidoglycan Strands in Lactobacillus helveticus Cell Walls
Max Firtel, Grant Henderson, Igor Sokolov
The internal cell wall structure of the bacterium Lactobacillus helveticus has been observed in situ in aqueous solution using an atomic force microscope (AFM). The AFM tip was use…
Visualization of Cytoskeletal Elements by the Atomic Force Microscope
T. Berdyyeva, C. D. Woodworth, I. Sokolov
We describe a novel application of atomic force microscopy (AFM) to directly visualize cytoskeletal fibers in human foreskin epithelial cells. The nonionic detergent Triton X-100 i…
