The direct reactions of PI(3) with -H or -C(6)H(5) substituted diiminopyridine ligands yield the N,N',N''-chelated P(I) cations. The analogous chemistry with the ubiquitous -CH(3) substituted derivative produces a complex mixture of products underscoring the importance of the substitution on the α-carbon atom. The I(3)(-) counteranion of the compounds could be easily exchanged with the more rob...

The Department of Health first outlined its plan for the implementation of activity-based funding in 2002 (Department of Health 2002). This was a radical move from previous ‘block contract’ arrangements where hospitals were given fixed amounts of money irrespective of their level of activity. Some of the advantages and disadvantages of the two systems are high lighted in Table 1. Payment by res...

Damaged replication forks activate poly(ADP-ribose) polymerase 1 (PARP1), which catalyses poly(ADP-ribose) (PAR) formation; however, how PARP1 or poly(ADP-ribosyl)ation is involved in the S-phase checkpoint is unknown. Here we show that PAR, supplied by PARP1, interacts with Chk1 via a novel PAR-binding regulatory (PbR) motif in Chk1, independent of ATR and its activity. iPOND studies reveal th...

This study experimentally demonstrated a feed-forward inversion control scheme for maintaining an optimum incident irradiance on photobioreactors (PBRs) during batch cultivation. A data-based modelfree optimization using quadratic fit was utilized to rapidly estimate the optimum average fluence rate set point value that rendered maximum microalgae growth rate. Then, the feed-forward inversion c...

The destruction of mass cultures of microalgae by biological contamination of culture medium is a pervasive and expensive problem, in industry and research. A mathematical model has been formulated that attempts to explain contaminant growth dynamics in closed photobioreactors (PBRs). The model simulates an initial growth phase without PBR dilution, followed by a production phase in which cultu...

The Undersea Networking environment presents many challenges, such as limited network throughput and extreme latency. It is further hampered by the challenges faced with all Mobile Ad-Hoc Networks, with regard to rapidly changing network topology, AdHoc routing overhead, and dynamic network size. AUSNet (Autonomous Undersea Systems Network) is an NSF funded STTR Phase 2 program (with support fr...

Requirements inspections are a process for improving the quality of software by allowing software developers to detect defects early in the lifecycle when they are cheaper to fix. One issue that arises is the experience level with a particular inspection technique an inspector needs before he or she is effective and efficient in using that technique. This technical report describes a study run ...

Performance-based regulation (PBR) is influenced by the Bayesian and non-Bayesian incentive mechanisms. While Bayesian incentives are impractical, the insights from their properties can be combined with practical non-Bayesian mechanisms for application to transmission pricing. This combination suggests an approach based on the distinction between ultra-short, short and long periods. Ultra-short...

In this paper, an effective target detection and localization method is proposed for a passive bistatic radar (PBR) system. The PBR system consists of a commercial FM radio station, which is a noncooperative illuminator of opportunity (IO), referred to as the transmitter antenna and multiple surveillance antennas that form an antenna array, e.g., uniform linear array (ULA). Unlike other literat...
