A Comparison of Radar Reflectivity Estimates of Rainfall from Collocated Radars
- E. Brandes, J. Vivekanandan, J. Wilson
- Environmental Science, Geography
- 1 September 1999
Abstract Radar reflectivity–based rainfall estimates from collocated radars are examined. The usual large storm-to-storm variations in radar bias and high correlation between radar estimates and rain… Expand
Quantitative Effects of Contrast Enhanced CT Attenuation Correction on PET SUV Measurements
- Tira Bunyaviroch, T. Turkington, T. Wong, J. Wilson, J. Colsher, R. Coleman
- Materials Science, Medicine
- Molecular Imaging and Biology
- 1 March 2008
PurposeThe presence of contrast materials on computed tomography (CT) images can cause problems in the attenuation correction of positron emission tomography (PET) images. These are because of errors… Expand
Composite Particle Reaction Theory
- J. Wilson
- Materials Science, Physics
- 1975
An effective potential operator is derived from the multiplescattering series expansion of the exact transition amplitude for scattering two composite particles. This effective potential operator is… Expand

NATURAL TRANSFER OF VIABLE MICROBES IN SPACE FROM PLANETS IN EXTRA-SOLAR SYSTEMS TO A PLANET IN OUR SOLAR SYSTEM AND VICE VERSA
- M. Valtonen, P. Nurmi, +7 authors C. Mileikowsky
- Physics
- 2 September 2008
We investigate whether it is possible that viable microbes could have been transported to the Earth from planets in extra-solar systems by means of natural vehicles such as ejecta expelled by comets… Expand
Space radiation dose estimates on the surface of Mars.
- L. Simonsen, J. Nealy, L. Townsend, J. Wilson
- Physics, Medicine
- Journal of spacecraft and rockets
- 1 August 1990
A future goal of the U.S. space program is a commitment to the manned exploration and habitation of Mars. An important consideration of such missions is the exposure of crew members to the damaging… Expand
Mars Surface Ionizing Radiation Environment: Need for Validation
Protection against the hazards from exposure to ionizing radiation ramains an unresolved issue in the Human Exploration and Development of Space (HEDS) enterprise. The major uncertainty is the lack… Expand

Martian regolith as space radiation shielding.
- L. Simonsen, J. Nealy, L. Townsend, J. Wilson
- Physics, Medicine
- Journal of spacecraft and rockets
- 1 February 1991
In current Mars scenario descriptions, an entire mission is estimated to take 500-1000 days round trip with a 100-600 day stay time on the surface. To maintain radiation dose levels below permissible… Expand
MA7-Measurement of the Temperature Dependence of the Vibrational Relaxation Rate of HF and the Effect
- S. Fried, J. Wilson, R. L. Taylor
- Chemistry, Physics
- 1973
Absfract-The vibrational relaxation of HF was measured by the laser-excited fluorescence technique over the temperature range of 295-730 I(. The results are in agreement with the 350 IC measurement… Expand
