AN INTEGRATE-AND-DUMP RECEIVER FOR FIBER OPTIC NETWORKS by ANDREW E. STEVENS The receiver in an optical communication system is a key component in determining the overall system performance. This thesis will present a new optical receiver which mathematically integrates the arriving bits with respect to time in order to improve receiver sensitivity. This so-called integrate-and-dump circuit is ...

2'-Fluoro-2'-deoxyuridine 3'-phosphate (dU(F)MP) and arabinouridine 3'-phosphate (araUMP) have non-natural furanose rings. dU(F)MP and araUMP were prepared by chemical synthesis and found to have three- to sevenfold higher affinity than uridine 3'-phosphate (3'-UMP) or 2'-deoxyuridine 3'-phosphate (dUMP) for ribonuclease A (RNase A). These differences probably arise (in part) from the phosphory...

Wikipedia, the well known internet encyclopedia, is nowadays a widely used source of information. To leverage its rich information, already parsed versions of Wikipedia have been proposed. We present an annotated dump of the English Wikipedia. This dump draws upon previously released Wikipedia parsed dumps. Still, we head in a different direction. In this parse we focus more into the syntactica...

1. OVERVIEW An undesirable situation could develop anytime during ERL operation, even if this could be treated as a rare event. So the protection system must be designed so that despite its occasional triggering, it must yield a controllable beam dump with ~100% probability. In mostly situations the faster dump system isthe lesser the damage could be. One typical example could be represented wh...

The enzyme thymidylate synthase (TS) catalyzes the reductive methylation of 2'-deoxyuridine 5'-monophosphate (dUMP) to 2'-deoxythymidine 5'-monophosphate. Using kinetic and X-ray crystallography experiments, we have examined the role of the highly conserved Tyr-261 in the catalytic mechanism of TS. While Tyr-261 is distant from the site of methyl transfer, mutants at this position show a marked...

Purpose – The aim of this work was to investigate longitudinal features of an established social questionanswering site to study how question-answer resources and other community features change over time. Design/methodology/approach – Statistical analysis and visualisation was performed on the full data dump from the StackOverflow social question-answering site for programmers. Findings – The ...

Aiming at developing a simple and efficient collision detection method to support the wandering in equipment deploy scene in land reclamation area of mining dump. This paper presents an efficient algorithm for collision detection in the waste dump land reclamation equipment deploy scene using a bounding volume nestification which consists of an oriented bounding boxes (OBBs) enhanced with axial...
