The scope of this work is to develop a technological platform specialized in assessing retinal vessel caliber and describing the relationship of the results obtained to cardiovascular risk. Population studies conducted have found retinal vessel caliber to be related to the risk of hypertension, left ventricular hypertrophy, metabolic syndrome, stroke, and(More)
Isotopic distributions for light particles and intermediate mass fragments have been measured for isotone, and isobar yield ratios are utilized to estimate the isotopic composition of the gas phase at freeze-out. Analyses within the equilibrium limit imply that the gas phase is enriched in neutrons relative to the liquid phase represented by bound nuclei.(More)
Collisions of 112 Sn and 124 Sn nuclei, which differ in their isospin asymmetry, provide information about the rate of isospin diffusion and equilibration. Although several different probes can provide accurate diffusion measurements, the ratios of the mirror nuclei may be the simplest and most promising one. Ratios of the mass seven mirror nuclei yields(More)
This article describes the crystal selection and quality control utilized to develop and calibrate a high resolution array of CsI(Tl) scintillator crystals for the detection of energetic charged particles. Alpha sources are used to test the light output variation due to thallium doping gradients. Selection of crystals with better than 1% non-uniformity in(More)
The caloric curve of the highly excited projectile spectators emerging from peripheral collisions of two Au-nuclei at 600 AMeV was determined by measuring fragments and neutrons of its decay. This analysis will be reviewed and preliminary results obtained from the decay also of the target spectator will be presented.
The energy spectra of light charged particles and intermediate mass fragments from 112 Sn + 112 Sn and 124 Sn + 124 Sn collisions at an incident energy of E/A = 50 MeV have been measured with a large array of silicon strip detectors. We used charged-particle multiplicities detected in an array with nearly 4π coverage to select data from the central(More)
We report on the first direct measurement of the proton separation energy for the proton-unbound nucleus 69 Br. Bypassing the 68 Se waiting point in the rp process is directly related to the 2p-capture rate through 69 Br, which depends exponentially on the proton separation energy. We find a proton separation energy for 69 Br of S p ð 69 BrÞ ¼ À785 þ34 À40(More)
A three parameter scaling relationship between isotopic distributions for elements with Z≤ 8 has been observed that allows a simple description of the dependence of such distributions on the overall isospin of the system. This scaling law (termed iso-scaling) applies for a variety of reaction mechanisms that are dominated by phase space, including(More)

Breakup temperatures in central collisions of 197 Au + 197 Au at bombarding energies E/A = 50 to 200 MeV were determined with two methods. Isotope temperatures, deduced from double ratios of hydrogen, helium, and lithium isotopic yields, increase monotonically with bombarding energy from 5 MeV to 12 MeV, in qualitative agreement with a scenario of chemical(More)
