Carboxypeptidase Y from bakers’ yeast is a diisopropyl phosphorofluoridate (DFP)-sensitive enzyme. The inactivation by Ia2P]DFP is accompanied by the formation of 1 mole of labeled serine per mole of enzyme. A 15-residue 32Plabeled (*) peptide has been isolated from a peptic digest and shown to have the sequence His-Ile-Ala-Gly-Glu-Ser*-TyrAla-His-Gly-Tyr-Ile-Pro-Val-Phe. The reaction of the se...

Diisopropyl fluorophosphate (DFP) effectively inhibited proteolytic activity in preparations of partially purified Streptomyces albus enzyme used to lyse cell walls of Group A streptococci. Lysis of non-trypsinized Group A cell walls with DFP-treated S. albus enzyme released a soluble protein fraction containing antigenic type-specific M protein, a carbohydrate fraction consisting of Group A an...

This paper presents an improved measure for the dynamic functionality of a logic circuit, called delay fault probability (DFP). The new measure reflects both the nominal delay of the paths and the fact that only few paths are critical for path delay fault testing. An efficient distributed algorithm for computing DFP is presented. The experimental results show that, in contrast to DFP, the conve...

Investigates the effects of two well-known carbamate~, physostigmine and pyridostiginine against organophosphorous compound and nerve gas toxicity. Physostigmine pretreatment for 30 min enhanced the survival time of rats against DFP intoxication whereas it did not have any effect with sarin poisoning. However, pyridostigmine pretreatment did not produce any significant effect on survival time e...

Diisopropylfiuorophosphate {OFP), a general serine protease inhibitor, inhibited the DNA fragme"tatioll and cell death in MDCK cells treated with ricin, modeccin, Ilseudomonas toxin, or dipbtberia toxin. Atrypsin-like serine protease inhibitor, IVLtosyl・L-lysine chleromethyl ketone (TLCK) also prevented ricin-induced DNA fragmentation and cel] death, albeit less effectiyely than DFP. Microscopi...

We study the convergence properties of decentralized fictitious play (DFP) for class near-potential games where incentives agents are nearly aligned with a potential function. In DFP, share information only their current neighbors in sequence time-varying networks, keep estimates other agents' empirical frequencies, and take actions to maximize expected utility functions computed respect estima...

This report describes a Device-Free Passive Localization System (DfP). The system provides a software solution over nominal WiFi equipment to detect the presence and track intruders in an area of interest. The system is based on measuring the changes in the received RSSI at a fixed receiver form a fixed transmitter. Using RSSI values for multiple transmitters and monitoring points, we show a sy...

In this study, a novel system for the detection and quantification of organofluorophosphonates (OFP) has been developed by using an optical sensing polymeric membrane to detect the fluoride ions produced upon OFP hydrolysis. Diisopropyl fluorophosphate (DFP), a structural analogue of type G chemical warfare agents such as Sarin (GB) and Soman (GD), is used as the surrogate target analyte. An op...

A total of 34,399 commercial nursery pigs (initially 12.2 lb) were used in 20 barns with 10 per treatment to determine the effectiveness a dried fermentation product (DFP) on pig mortalities, antibiotic injection frequency, and close-out growth performance. The target dosage DFP for first 14 d was 35 mg/kg BW based actual previous experiment. Following 14-d supplementation period, continued be ...

Dataflow Programming (DFP) has been a research topic of Software Engineering since the ‘70s. The paradigm models computer programs as a direct graph, promoting the application of dataflow diagram principles to computation, opposing the more linear and classical Von Neumann model. DFP is the core to most visual programming languages, which claim to be able to provide end-user programming: with i...
