• #### A laser diode system and its use in a laser cooling experiment ﻿

(1992)
A system to control and stabilize the output of visible laser diodes was developed and used to measure the velocity distribution of lithium atoms in a laser cooling experiment. Circuitry was designed and built for controlling ...
• #### A quasi-elastic neutron scattering study of hydrogen dynamics in trypsin-deuterium oxide solution (deuterium oxide) ﻿

(1993)
The quasi-elastic neutron scattering (QNS) method is a useful technique to study biomolecular dynamics. The versatility of the method makes possible motional studies of biomolecules in different forms: powder, crystalline, ...
• #### Analysis and interpretation of gamma-ray burst continuum spectral evolution with BATSE data ﻿

(1999)
Once a day, a flash of gamma-rays erupts somewhere in space and is detected by an international fleet of satellites. Since their first detection over a quarter century ago, these gamma-ray bursts have puzzled researchers ...
• #### Analysis of a Liquid Droplet Radiator by Galerkin's method with an improved profile ﻿

(1989)
The Liquid Droplet Radiator is a proposed lightweight radiator for the dissipation of waste heat generated by power plants in space. The hot working fluid is sprayed into space as coherent streams of tiny, discrete droplets, ...

(1972)
• #### Experimental setup for the operation of gas electron multipliers in liquid-gas xenon detectors ﻿

(2004)
A setup for the realization of dual-phase experiments using xenon as the active medium in a radiation detector has been built. The setup consists of a gas purification system capable of achieving a purity of the gas in the ...

• #### Gamma radiation from certain nuclear reactions ﻿

(1953)
A study of the emission of gamma rays from excited nuclei is an important means to the identification of the nuclear levels involved. By observations of cascade versus single transitions and the relative probabilities of ...
• #### Gamma ray observations of black hole candidates nova Ophiuchus 1993 and nova Velorum 1993 ﻿

(1997)
Results of spectral analysis and time series analysis of the transient source x-ray nova Velorum 1993 (GRS 1009-45) and x-ray nova Ophicuhus 1993 (GRS 1716-249) are presented. These data were accumulated using the OSSE ...
• #### Helium gas Cherenkov detector ﻿

(1989)
We designed and built a large gas Threshold Cherenkov Counter at the Bonner Nuclear Laboratory of Rice University to be used in Fermilab-experiment E-704. We tested and calibrated the detector with an electron beam of 30 ...
• #### Investigation of atomic motion in an intense standing light wave and application to adiabatic laser cooling of atoms ﻿

(1993)
The effect of the dipole force and its fluctuation on the motion of Li atoms in an intense, one-dimensional, near-resonant standing light wave has been investigated, both theoretically and experimentally. The duration of ...
• #### Numerical Investigation of Medical Applications of Nanoparticles toward Tumor/Cancer Diagnosis and Treatment of ﻿

(2013-07-24)
Almost a decade has passed ever since the first time nanoparticles were proposed to be used for tumor/cancer diagnosis and treatment. For tumor/cancer treatments, nanoparticles are usually engineered to be the photo-thermal ...
• #### Observational and theoretical interpretation of energetic particle transport in solar flares ﻿

(2008)
The combination of excellent space-based remote sensing, and image reconstruction techniques, as well as improvements in numerical modeling, help enhance our understanding of particle transport in solar flares. We conduct ...
• #### Phase modulation by high density laser-produced plasmas ﻿

(1994)
A model for simulation of laser produced plasmas that couples absorbed energy, plasma dynamics and radiation pressure was developed. The unusual experimental result of spectral narrowing of reflected laser pulses was ...
