WASP0 is a prototype for what is intended to become a collection of wide-angle survey instruments whose primary aim is to detect extra-solar planets transiting across the face of their parent star. The WASP0 instrument is a wide-field (9-degree) 6.3cm aperture F/2.8 Apogee 10 CCD camera (2Kx2K chip, 16-arcsec pixels) mounted piggyback on a commercial telescope. We present results from analysis ...

Hardware Transactional Memory (HTM) schemes usually piggyback onto the cache coherence protocol to detect data access conflicts between transactions. We identify an intrinsic mismatch between the coherence scheme and transaction execution which causes a sizable amount of unnecessary transaction aborts. This pathological behavior is called false aborting and increases the amount of wasted comput...

Message logging protocols ensure that crashed processes make the same choices when re-executing nondeterministic events during recovery. Causal message logging protocols achieve this by piggybacking the results of these choices (called determinants) on the ambient message traffic. By doing so, these protocols do not create orphan processes nor introduce blocking in failure-free executions. To s...

Recombinant N-myristoyltransferase of Plasmodium falciparum (termed PfNMT) has been used in the development of a SPA (scintillation proximity assay) suitable for automation and high-throughput screening of inhibitors against this enzyme. The ability to use the SPA has been facilitated by development of an expression and purification system which yields considerably improved quantities of solubl...

This is a retrospective analysis of 10 mg metoclopramide, 25 mg diphenhydramine, and 4 mg dexamethasone given intravenous piggyback every 6 hours for nausea or vomiting. Outcome measures were rapidity of symptom relief based on the self-report of the patient and nursing documentation of relief from symptoms of nausea or vomiting. Seven hundred and ninety seven patients were admitted to the inpa...

It has been recently shown that mobility in ad hoc networks can be an advantage instead of an inconvenience. Nevertheless, one class of mobile elements has been neglected up-to-date: data packets. In this paper, we propose to take advantage of the inherent mobility of data packets to disseminate location information throughout the network. We focus on the age-and-position based (APB) routing ca...
