The kinetic mechanism of lipoamide dehydrogenase has been studied at pH 8.0, 37”, using the enzyme from rat liver mitochondria. Initial velocity patterns obtained for both the forward and reverse reactions were a series of parallel lines. Michaelis constants for the reactants are: NAD, 0.52 mu; dihydrolipoamide, 0.49 mu; NADH, 0.062 mM; lipoamide, 0.84 mu. Isotopic exchange between NAD and NADH...

A recently developed system that uses pitched sounds to discover relative 3D positions of a group of devices located in a shared physical space is described. The measurements are coordinated over an IP network in a decentralized manner, while the actual measurements are carried out measuring the time-of-flight of the notes played by different devices. Approaches to sonify the discovery process ...

Since Bennett and Brassard presented the pioneer quantum key distribution (QKD) protocol in 1984 [1], there are a lot of theoretical QKD schemes [1-12] today. Recently, Beige et al. proposed a quantum secure direct communication scheme [13], which allows messages communicated directly without first establishing a random key to encrypt them. Bostroem and Felbingeer presented a ping-pong protocol...

Getting to the inner circle ontiguity between the ER and the nuclear envelope means nuclear membrane proteins have a direct shot to their target. In fact, inner nuclear membrane (INM) proteins were thought to need only to diffuse to the nucleus, pass through the nuclear pore, and then be retained by nuclear-localized binding partners. But new results suggest a more active process. Suraj Saksena...

This paper presents an Optimised Handover (HO) Algorithm for Dense Wireless Local Area Networks (WLANs) based on a novel architecture of Software Defined Network (SDWN). The work has been designed to be effective in large network environments with high density Access Points (APs) and stations, which increase the chances Ping-Pong HO effect. Specifically, it considers Quality Experience (QoE) by...

BACKGROUND Cutaneous injury following impact of a high velocity ball to the skin may result in either erythema or purpura or both. The lesion typically appears as an annular ring of erythema with or without accompanying ecchymosis when the skin is contacted by a paintball, a ping pong ball, a racquetball or a squash ball. PURPOSE To describe a girl with targetoid erythema following impact of ...
