We report a measurement of the parity-violating asymmetry in fixed target electron-electron (Møller) scattering: A(PV)=[-175+/-30(stat)+/-20(syst)] x 10(-9). This first direct observation of parity nonconservation in Møller scattering leads to a measurement of the electron's weak charge at low energy Q(e)(W)=-0.053+/-0.011. This is consistent with the(More)
UNLABELLED USES: Diquat (1,1'-ethylene-2,2'-bipyridilium) is a nonselective bipyridyl herbicide, related structurally to paraquat, which is used both as a contact herbicide and a preharvest desiccant. In comparison to paraquat, diquat is used much less widely in agriculture. MECHANISMS OF TOXICITY Diquat is a potent redox cycler and is readily converted(More)
Pseudopseudohypoparathyroidism and pseudohypoparathyroidism have been thought to represent variants of the same disease process, Albright hereditary osteodystrophy. A 31-year-old woman with the characteristic features of pseudopseudohypoparathyroidism, such as shortened metacarpals and metatarsals, round facies, and normal serum calcium values, was studied.(More)
When possible, many species will shift in elevation or latitude in response to rising temperatures. However, before such shifts occur, individuals will first tolerate environmental change and then modify their behavior to maintain heat balance. Behavioral thermoregulation allows animals a range of climatic tolerances and makes predicting geographic(More)
We present data on the inclusive scattering of polarized electrons from a polarized 3He target at energies from 0.862 to 5.06 GeV, obtained at a scattering angle of 15.5 degrees. Our data include measurements from the quasielastic peak, through the nucleon resonance region, and beyond, and were used to determine the virtual photon cross-section difference(More)
Using an InAs/GaSb composite quantum well, we demonstrate an enhancement mode single electron transistor. With a Hall bar geometry, we show that the device undergoes a transition from accumulation of two-dimensional (2D) holes in GaSb to a complete depletion and finally to an inversion layer of 2D electrons in InAs. When the top-gate area is reduced to(More)
We assessed the occupancy dynamics of 275 California Spotted Owl (Strix occidentalis occidentalis) territories in 4 study areas in the Sierra Nevada, California, USA, from 1993 to 2011. We used Landsat data to develop maps of canopy cover for each study area, which we then used to quantify annual territory-specific habitat covariates. We modeled the(More)
A method for rapidly determining bound and free testosterone in human plasma is evaluated and described, in which dextran-coated charcoal is used to separate bound and free testosterone. Intra- and inter-assay CV's were 1.9 and 3.8%, respectively. At least 50% of the "bound" testosterone was associated with species that behaved like sex steroid(More)
