EEG of human and experimental injury model of rats are investigated. In both conditions TE decreases in bad physiological functional outcome. As the brain recovers from injury, the TE will also gradually return to normal level. Meanwhile, TE also shows good sensitivity to different grades of asphyxic injury. This method provides a novel real time brain injury indicator and may be a useful in developing a diagnostic monitoring tool.

The basis of the HiRad design is the Stepped Frequency Microwave Radiometer (SFMR) that has successfully measured surface wind speed and rain rate in hurricanes from the NOAA Hurricane Research Division s P-3 aircraft. Unlike the SFMR that views only at nadir, the HiRad provides wide-swath measurements between +/- 45 deg. in incidence angle with a spot-beam spatial resolution of approximately 1-3 km. The system operates at four equally spaced frequency channels that cover a range between 4 GHz and 6 GHz. The final report consists of two parts. Part 1 is a reprint of a conference proceeding presented at the 2002 International Geoscience and Remote Sensing Symposium and authored by the principle members of the HiRad design team. Part 2 is a summary of the MMIC receiver design developed to support the HiRad sensor.

Four groups of clinical applications of dynamic infrared imaging are reviewed from the standpoint of their data processing following FFT analysis of temperature modulation and modulation of perfusion of the cutaneous capillary bed. These include: 1, Visual assessment of spatial abnormalities in perfusion kinetics that can be used in diagnosis of joint disease and of advanced cancer, as well as visual identification of abnormalities in subcutaneous circulation, 2, Objective computerized diagnosis of systemic chronic neuronal disorders that may affect modulation amplitudes and their spatial distribution, 3, Objective computerized detection of cancer, breast and skin cancer in particular, by their effect on the spatial distribution of attenuated subareas at specific frequencies of modulation, 4, Objective assessment of transient mental stress (psychological testing) and of exposure to neurotoxic agents that may affect modulation amplitudes and their distribution over limited periods of time. Following time- dependent changes in temperature modulation at specific frequencies one can assess the severity of functional perturbation of the autonomic nervous system.

These biosensors will provide a novel tool which permits major advances in the investigation and control of fundamental molecular and cellular physiological processes. There are three aspects of our approach: 1. Using nanotechnology and existing sensing mechanisms for nanometer level biosensor development; 2. Using molecular beacon DNA molecules for development of new biomolecule recognition mechanisms; 3. Using single molecule microscopy techniques for molecular interaction studies. Over the three years of this grant, we have published 20 papers and filed two patents (one granted and one pending). The grant also has helped us to train six graduate students, three postdoctoral researchers, five undergraduate students. Among all the students, there are two African American graduate students, one Hispanic graduate student and three minority undergraduate students. The grant has also enabled us to build a world class research laboratory in the area of biomolecular interaction and recognition studies.

T.; Maitland, D. J.; Dec. 10, 1999; 16 pp.; In English Report No.(s): DE2002-791683; No Copyright; Avail: Department of Energy Information Bridge Imaging through biologic tissue relies on the discrimination of weakly scattered from multiply scattered photons. The degree of polarization can be used as the discrimination criterion by which to reject multiply scattered photons. Polarized light propagation through biologic tissue is typically studied using tissue phantoms consisting of dilute aqueous suspensions of microspheres. We show that, although such phantoms are designed to match the macroscopic scattering properties of tissue, they do not accurately represent biologic tissue for polarization-sensitive studies. In common tissue phantoms, such as dilute Intralipid and dilute 1-microm-diameter polystyrene microsphere suspensions, we find that linearly polarized light is depolarized more quickly than circularly polarized light. In dense tissue, however, where scatterers are often located in close proximity to one another, circularly polarized light is depolarized similar to or more quickly than linearly polarized light. We also demonstrate that polarized light propagates differently in dilute versus densely packed microsphere suspensions, which may account for the differences seen between polarized light propagation in common dilute tissue phantoms versus dense biologic tissue.

Darren; Harper, D. Al; Jhabvala, Murzy D.; [2002]; 10 pp.; In English; SPIE Conference on Astronomical Telescopes and Instrumentation, 22-28 Aug. 2002, Waikoloa, HI, USA; Original contains black and white illustrations; Copyright; Avail: CASI; A02, Hardcopy The High resolution Airborne Wideband Camera (HAWC) and the Submillimeter High Angular Resolution Camera II (SHARC II) will use almost identical versions of an ion-implanted silicon bolometer array developed at the National Aeronautics and Space Administration’s Goddard Space Flight Center (GSFC). The GSFC ‘Pop-up’ Detectors (PUD’s) use a unique folding technique to enable a 12 x 32-element close-packed array of bolometers with a filling factor greater than 95 percent. A kinematic Kevlar(trademark) suspension system isolates the 200 mK bolometers from the helium bath temperature, and GSFC - developed silicon bridge chips make electrical connection to the bolometers, while maintaining thermal isolation. The JFET preamps operate at 120 K. Providing good thermal heat sinking for these, and keeping their conduction and radiation from reaching the nearby bolometers, is one of the principal design challenges encountered. Another interesting challenge is the preparation of the silicon bolometers. They are manufactured in 32-element, planar rows using Micro Electro Mechanical Systems (MEMS) semiconductor etching techniques, and then cut and folded onto a ceramic bar. Optical alignment using specialized jigs ensures their uniformity and correct placement. The rows are then stacked to create the 12 x 32-element array. 90
