PROJECT SUMMARY Cardiac valve repair or replacement is indicated when progression of degenerative disease or bacterial infection of the native valve results in valvular dysfunction, thereby impacting cardiac output. Both procedures require the use of a woven or knitted polyester material with an internal reinforcement (Teflon, silicone or metal) to either stabilize the native valve (annuloplasty r ...

TIAX will build, characterize and abuse test lithium-ion cells employing LiCoPO4 cathodes and control metal-oxide based cathodes (such as LiCoO2 ) opposite graphite anodes. In Phase I, TIAX will perform overcharge and external short circuit tests to the specification of the UL1642 standard and will also perform nail penetration tests on both types of cells. In the option program TIAX will perfor ...

Although great strides have been made in the development of simulators for training technical and teamwork skills, much less progress has been made with regard to skill assessment. Typically, performance is measured using a rating scale with anchors ranging from"low"to"high."Such methods are too coarse to provide an accurate assessment of individual or team performance. What is needed are unobtrus ...

DESCRIPTION (provided by applicant): We propose to develop a compact, cost-effective Traveling Wave Tube (TWT) amplifier at 263 GHz with 50 W of peak power, 5 W of continuous wave power and 5% instantaneous bandwidth for application in Dynamic Nuclear Polarization (DNP) enhanced solid-state and solution-state NMR and Electron Paramagnetic Resonance (EPR) spectroscopy. With DNP, the inherently smal ...

In this STTR, OASIS Inc, with partners the Massachusetts Institute of Technology (MIT) and the Applied Physics Laboratory University of Washington (APL-UW) proposes to develop an innovative, interactive submarine acoustic counter detect TDA for use by the Submarine Mission Planners, within the AN/BYG-1. Communicating the environmental and tactical uncertainty is of primary importance when present ...

Through this effort, the team of Materials Systems Inc. (MSI) and Sonic Tech, Inc. (STI) will develop a non-destructive evaluation technique for detection of voids and defects underneath Aluminum Matting-2. The MSI scanning concept fully utilizes its expertise in the design and development of piezocomposite transducer arrays, combined with STI's experience in acoustic system development and s ...

DESCRIPTION (provided by applicant): Retransfusion of a patient's shed blood during cardiopulmonary bypass is attractive since it reduces the need for allogeneic transfusion, minimizes cost, and decreases transfusion related morbidity. Heterologous transfusions are linked to increased long term mortality after cardiac surgery. However, brain damage after cardiac surgery with retransfusion of ...

DESCRIPTION (provided by applicant): A Culture-Free Platform for Rapid Pathogen Identification Project Summary Sepsis is a one of the leading causes of morbidity and mortality in the US, with more than 751,000 confirmed cases occurring every year and 210,000 mortalities. This high mortality rate (~30%) means that nearly 600 patients a day succumb to sepsis-related infections. In addition to the hu ...
