This paper provides an informative discussion of some aspects of the use of n-position area averaging in absolute testing of optical surfaces. The paper may
The effects of the number of histogram bins on histogram-derived pulse parameters of step-like waveforms is examined. An empirical method for selecting the
The phenomenon of breathing mode excitation or bound state wave packet squeezing and spreading driven by a time-dependent oscillator frequency [due to either a
This paper presents a magnetization interpolation method for micromagnetic exchange energy calculations using a variational procedure to relax spins on a

In this work a method is developed that allows the computation of the single- crystal elastic constants for crystals of cubic symmetry from the diffraction
An atomic-levellmechanical hardness model that is based on screened electrostatics and elastic shear (SEES) is generalized to single-phase substitutional
Using 40 ns laser pulses, we probe the real-time dynamics of ultra-cold ionizing collisions in metastable xenon. We time-resolve both shielding and enhancement

Apparent equilibrium constants and calorimetric enthalpies of reaction have been measured for the following enzyme-catalyzed biochemical reactions at the
Models commonly used to calculate the thermodynamic properties of refrigerants are summarized. For pure refrigerants, the virial, cubic, Martin-Hou, Benedict
