The well-known Late Cretaceous Lameta Ghat locality (Jabalpur, India) provides a window of opportunity to study a large stable, near shore sandy beach, which was widely used by sauropod dinosaurs as a hatchery. In this paper, we revisit the eggs and eggshell fragments previously assigned to lizards from this locality and reassign them to crocodylomorphs.(More)

This paper presents different techniques to improve the bandwidth and power efficiency of negative-C compensated amplifiers for high speed applications. Criteria for stability and other design aspects are also discussed. Bandwidth enhancement and power efficiency of proposed approaches when compared to the classical negative-C compensation technique are(More)
INTRODUCTION We report the case of an unusual association of Coffin-Siris syndrome with Mayer-Rokitansky-Küster-Hauser syndrome. This association has never previously been reported in the medical literature. CASE PRESENTATION A nine-year-old Indian girl was referred to our hospital for growth retardation, mental retardation, lax joints, generalized(More)
—Ultra-wideband (UWB) technology is being proposed for several short range wireless applications. Some of the applications, such as position location devices for rescue personnel, may require the antenna height to be close to the ground. In scenarios where the antenna height is very low (from 0 to 30 cm), propagation characteristics and channel modeling are(More)
