SAFE HAVENS AND HOT SPOTS: IONIZING RADIATION IN MARTIAN PERMAFROST AND ITS INFLUENCE ON THE SURVIVAL OF ANCIENT LIFE
(East Carolina University, 2022-06-20)Permafrost on Mars is considered a primary target for the search for life. On a microscopic scale permafrost is highly non-uniform and the effective radiation dose absorbed by a microbe, and thus its survival probability, ... -

Secondary Electron Emission Yields from Fast Fluorine Ions on Copper and Amorphous Solid Water Foils
(East Carolina University, 2011)The biological outcomes from charged particle radiation exposure are heavily influenced by the spatial patterns of energy distributed within the biological system. Monte Carlo track structure codes can be used to model ... -
Soundscapes from a Saltwater Creek Captured by a Hydrophone Array
(2022-07-11)Soundscape recordings allow listeners to know about the presence and activities of soniferous animals in an area, and these recordings have been used to learn about both terrestrial and aquatic environments. If we want to ... -
Study of Morphology Based Cell Assay by Diffraction Imaging Flow Cytometry
(East Carolina University, 2015)Development of an accurate and label-free method for single cell assay attracts intensive research efforts for its importance to cell biology research and clinicG14G7al applications. Flow cytometry is one of the most widely ... -
Superdormant Spores of Bacillus Species Have Elevated Wet-Heat Resistance and Temperature Requirements for Heat Activation
(East Carolina University, 2009-09)Purified superdormant spores of Bacillus cereus, B. megaterium, and B. subtilis isolated after optimal heat activation of dormant spores and subsequent germination with inosine, D-glucose, or L-valine, respectively, germinate ... -
The Effects of Low-Energy Heavy Charged Particles on the Optically Stimulated Luminescence and Thermoluminescence of Aluminum Oxide and Beryllium Oxide
(East Carolina University, 2021-06-02)Optically Stimulated Luminescence (OSL) and Thermoluminescence (TL) are methods utilized to evaluate the energy absorbed by crystalline insulators. It is necessary to test luminescent materials in a controlled environment ... -
The shear viscosity of quark-gluon plasma under anisotropic scatterings
(East Carolina University, 2022-05-02)Quark-gluon plasma (QGP) is a state of matter that is formed from relativistic heavy-ion collisions and also in the early universe. The quarks and gluons as quasi-free particles resemble an expanding viscous liquid under ... -
uantitative characterization of turbidity by radiative transfer based reflectance imaging
(2018-04-04)A new and noncontact approach of multispectral reflectance imaging has been developed to inversely determine the absorption coefficient of μ a , the scattering coefficient of μs and the anisotropy factor g of a turbid ...
