We demonstrate low residual timing jitter of 10 GHz pulses from a 1.55 m optical frequency comb generator based on a doubly-resonant electro-optic modulator
Correlations are one of the central features of modern condensed matter physics. They arise in systems where the behavior of any given particle in a system
Molecular dynamics simulations are used to examine the local solvation structure of single octane and perfluorooctane molecules in liquid water, methanol
Low water to cement ratio (w/c) concrete exhibits increased occurrences of early-age shrinkage cracking. These occurrences have spawned innovative developments

The pair correlation functions for a mixture of two Lennard-Jones (LJ) particles were computed by both the Percus-Yevick equations and by molecular dynamics
Ratio calibration of a digital voltmeter (DVM) is critical for some applications such as load cell response for force measurement. The NIST DVM ratio service
Consider an ill-posed problem transformed if necessary so that the errors in the data are independent, identically normally distributed with mean zero and
Pairwise testing has become a popular approach to software quality assurance because it often provides effective error detection at low cost. However, pairwise
