This article describes the use of optical methods based on picosecond transient gratings to stimulate and detect ultrasonic acoustic modes in several important structures with dimensions less than
Coherent-based systems are very good candidates to upgrade 10 Gb/s WDM infrastructures thanks to their high spectral efficiency and unique resistance to linear impairments, but their poor tolerance
We present ab initio calculations of the cohesive properties of Ge, Si and Diamond.
ADAR systems in current use radiate short bursts of energy developed by pulsing a high-frequency generator, usually a magnetron.
A generalization of Zimm's bead-spring model for dilute solutions of flexible polymers that accounts for the influence of coil distortion on hydrodynamic interaction is used to calculate molecular
The construction of coin-collectors, their operating features and the requirements and limits of different types in general use in the United States are discussed.
Cerebellar long-term depression (LTD) is a calcium-dependent process in which coincident activity of parallel fiber (PF) and climbing fiber (CF) synapses causes a long-lasting decrease in PF synapt
We demonstrate the flexibility that a wavelength selective switch could offer to bandwidth provisioning of potential multi-user quantum key distribution networks based on entangled pair sources.
A number of practical problems are questions about what we call "coincidences" in Poisson patterns.
Gas discharge tubes have found extensive use in telephone switching and other digital systems.
