ABSTRACT: The objective of this effort is to develop next-generation architectural and operational concepts, leveraging recent advances in High Performance Computing (HPC) technologies, to improve Wide Area Motion Imagery (WAMI) tracking capacity and performance. WAMI systems typically produce tens of thousands of moving target indicator (MTI) detections from city-sized urban areas at update rat ...

DESCRIPTION provided by applicant Cancer is the second leading cause of death after heart disease in the US Chemotherapy is a mainstay of treatment after surgical removal of tumors but the balance of clinical benefit versus disabling or life threatening side effects is often uncertain Genotyping of cancers to identify mutated oncogenes has enabled an era of targeted therapy Drugs targeting ...

DESCRIPTION provided by applicant Neurodegeneration in Alzheimerandapos s disease AD may result from deposition of A as plaques in brain tissue However less effort has been made to elucidate the role of tau containing neurofibrillary tangles NFTs in AD Accumulating evidence suggests that tau containing NFTs is an important component in the initiation and progression of AD and other neu ...

ABSTRACT: Shared Spectrum Company (SSC) partners with Virginia Tech (VT) to develop resilient and agile space communication systems using innovative cognitive radio techniques. The objective of this STTR Phase II project is to develop anti-jamming capability using frequency agility provided by Dynamic Spectrum Access (DSA) technology for satellite communications (SATCOM) systems. The SSC team foc ...

DESCRIPTION provided by applicant For this Phase II STTR proposal the investigators plan to develop and commercialize the radiofrequency RF coil technology to make T body MRI possible and to translate this new technology to vastly improve T clinical MRI as well In the Phase I project leading to this proposal all specific aims were accomplished to demonstrate the feasibility of safely an ...

ABSTRACT: Close integration of photonic devices with silicon complementary metal-oxide semiconductor (CMOS) electronics can yield significant performance improvements in many applications. The recent development of novel integrated structures in silicon including waveguides, resonators, and photodetectors will enable dramatic reductions in size, weight, and power for components implementing compl ...

ABSTRACT: Low frequency antennas provide us with the most critical challenge in small UAVs due to the limited available real estate on the platform. The primary objective of our Phase I research was to fill a critical technology gap in small UAVs for low frequency communication and SIGINT applications. We carried out a very comprehensive Phase I research to develop light-weight, conformal volumet ...

ABSTRACT: SSC and VT develop algorithms and approaches to manage uncertainty in dynamic spectrum access (DSA) systems for small satellite constellations. We use various DSA rule sets such as sensing, database, and monitoring systems to reduce the uncertainty on a systems level. We investigate uncertainty modeling using Dempster-Schafer theory to build belief, disbelief and ignorance maps of spe ...

ABSTRACT: Due to scarcity of spectrum, Dynamic Spectrum Access (DSA) becomes a needed technology to improve the utilization of electromagnetic spectrum for DoD satellite communication. However, current DSA approaches are developed for terrestrial communications without addressing the unique challenges for SATCOM environments such as error-prone spectrum sensing, high mobility, and large coverage. ...

DESCRIPTION provided by applicant The thalassemias and sickle cell disease are serious genetic blood diseases which are WHO designated as a growing global health burden The disorders decrease production or alter structure of the b chain of adult hemoglobin A and are characterized by anemia chronic organ damage and early mortality HbF is another type of normal hemoglobin which is suppres ...
