The synthetic sex pheromone (gossyplure) of the pink bollworm was evaporated into the atmosphere of three cotton fields during an entire growing season. The resulting disruption of premating pheromone communication between male and female moths led to a reduction in the population of larvae infesting cotton bolls. This larval control was comparable, in(More)
The Laser Interferometer Gravitational-Wave Observatory has performed a third science run with much improved sensitivities of all three interferometers. We present an analysis of approximately 200 hours of data acquired during this run, used to search for a stochastic background of gravitational radiation. We place upper bounds on the energy density stored(More)
The standardized uptake value (SUV) and the slope of the Patlak plot ( K) have both been proposed as indices to monitor the progress of disease during cancer therapy. Although a good correlation has been reported between SUV and K, they are not equivalent, and may not be equally affected by metabolic changes occurring during disease progression or therapy.(More)
UNLABELLED Standardized uptake value (SUV) is often used to quantify (18)F-FDG tumor use. Although useful, SUV suffers from known quantitative inaccuracies. Simplified kinetic analysis (SKA) methods have been proposed to overcome the shortcomings of SUV. Most SKA methods rely on a single time point (SKA-S), not on tumor uptake rate. We describe a hybrid(More)
Enzymes that efficiently hydrolyze highly toxic organophosphorus nerve agents could potentially be used as medical countermeasures. As sufficiently active enzymes are currently unknown, we synthesized twelve fluorogenic analogues of organophosphorus nerve agents with the 3-chloro-7-oxy-4-methylcoumarin leaving group as probes for high-throughput enzyme(More)
The efficacy of lithium carbonate as a treatment for alcoholism was examined in a double-blind, placebo-controlled study of 104 men and women meeting DSM-III criteria for alcohol dependence. Subjects entered the study during inpatient treatment and were subsequently followed up for 12 months. Survival analysis disclosed essentially three categories of(More)
The efficacy of lithium therapy for alcoholism was examined in 84 alcoholic volunteers admitted for rehabilitation. Subjects were randomly assigned to a lithium or placebo treatment condition for 18 months, and were reinterviewed monthly to document their compliance, drinking status, and mood. Two separate factors contributed to abstinent outcome:(More)
The internal consistency of the Beck Depression Inventory (BDI) is assessed in 106 inpatient alcoholics by using a latent trait model. The analysis confirms that the BDI measures a single underlying dimension of depressive severity among alcoholics. Seven symptoms discriminate well for severity of depression. These seven--work inhibition, guilt,(More)
We present a LIGO search for short-duration gravitational waves (GWs) associated with soft gamma ray repeater (SGR) bursts. This is the first search sensitive to neutron star f modes, usually considered the most efficient GW emitting modes. We find no evidence of GWs associated with any SGR burst in a sample consisting of the 27 Dec. 2004 giant flare from(More)
The Laser Interferometer Gravitational-wave Observatory (LIGO) has performed the fourth science run, S4, with significantly improved interferometer sensitivities with respect to previous runs. Using data acquired during this science run, we place a limit on the amplitude of a stochastic background of gravitational waves. For a frequency independent(More)
