We present AutoWitness, a system to deter, detect, and track personal property theft, improve historically dismal stolen property recovery rates, and disrupt stolen property distribution networks. A property owner embeds a small tag inside the asset to be protected, where the tag lies dormant until it detects vehicular movement. Once moved, the tag uses(More)
The fluorescence emission maximum of a polar fluorophore in viscous medium often shows a dependence on excitation wavelength, a phenomenon which is named red edge excitation shift (REES). We have found that the fluorescence spectra of the tubulin tryptophans exhibit a REES of about 7 nm. Also, their steady state fluorescence polarization and mean lifetimes(More)
The study included 45 consecutive patients in the age group of 27 to 39 years presenting with AMI diagnosed by typical history, ECG changes and enzyme response. Prognostic significance of various risk factors in AMI in young was evaluated. There were 41 M (91.1%) and 4 F (8.9%) with mean age of 34.6 years. ECG showed anterior myocardial infarction (MI) in(More)
AIMS & OBJECTIVES Platelet aggregation is a key factor behind coronary artery disease. Various complications after an attack of acute coronary syndrome are often related to the platelet hyperactivity in the early hours following the event. There is a growing concern regarding aspirin & clopidogrel resistance, which has put the time-tested therapies under(More)
Body area sensor networks measure biomedical signals from subjects continuously, as they go about their daily lives. Signals measured in these conditions are affected by anomalies, such as artifacts and noise. Some anomalies can be corrected, if detected in real-time, for example, ECG electrode detachment. We present energy and computationally efficient(More)
BACKGROUND AND OBJECTIVE The incidence of coronary artery disease (CAD) is increasing in India. Recent data suggesting insulin resistance can predict cardiovascular disease independently of the other risk factors, such as hypertension, visceral obesity, or dyslipidemia, so a focus on the relation between acute coronary syndrome (ACS) and insulin resistance(More)
BACKGROUND AND OBJECTIVES India is the second most populous country in the world and two-thirds of its population is less than 35 years old. This survey was conducted to assess the level of health awareness of cardiovascular disease in adolescent school-aged children 14-16 years old, with the goal of establishing school-based health education and(More)
The AutoWitness project aims to deter, detect, and track theft of everyday objects using a combination of ultra lowpower mobile tags and a wide-area network of static anchors. Key research challenges include dramatically driving down the cost and size of tags and increasing their lifetime, discriminating between normal activities and theft using motion(More)
AIMS AND OBJECTIVES Recurrent ischemic events continue to occur despite combination anti-platelet therapy. Currently aspirin, clopidogrel and dual resistance are increasingly recognized entities. The relationship of such resistance to recurrent ischemic events is largely unknown. In this study, we tried to gain an insight into the role of antiplatelet drug(More)
