The performance of a new high-flux solar simulator consisting of 18 × 2.5 kWel radiation modules has been evaluated. Grayscale images of the radiative flux distribution at the focus are acquired for each module individually using a water-cooled Lambertian target plate and a CCD camera. Raw images are corrected for dark current, normalized by the exposure time and calibrated with local absolute ...

A contact interaction analysis is presented to search for new phenomena beyond the Standard Model in deep inelastic ep → e hadrons scattering. The data are collected with the H1 detector at HERA and correspond to integrated luminosities of 0.909 pb and 2.947 pb for electron and positron beams, respectively. The differential cross sections dσ/dQ are measured in the Q range between 160 GeV and 20...

On May 24, 2001 United States Senator James Jeffords announced that he was switching from Republican to independent and would vote with Democrats on organizational matters, effectively taking majority party control of the Senate from the Republicans and giving it to the Democrats. This created an unusually well controlled quasi-experimental opportunity for learning about the role of parties in ...

The purpose of the study was to examine the effects of computer use on children’s social skills in kindergarten. Early Childhood Longitudinal Study-Kindergarten Class of 1998-99 (ECLS-K), conducted by National Center for Educational Statistics, was utilized to analyze differential effects of home and school computer use on kindergarten social skills gains. The sample included 12,929 kindergarte...

Within drug discovery, it is desirable to determine whether a compound will penetrate and distribute within the central nervous system (CNS) with the requisite pharmacokinetic and pharmacodynamic performance required for a CNS target or if it will be excluded from the CNS, wherein potential toxicities would mitigate its applicability. A variety of in vivo and in vitro methods for assessing CNS ...

The olive fruit fly Bactrocera oleae targets the fruits of olive trees in the Mediterranean and has been causing increasing economic harm to Californian growers. Past efforts to combat Bactrocera oleae by limiting the spread of its population have included traps, bait sprays, barrier films, and the release of natural predators, but these methods do little against large populations and many frui...

What is the impact of a legislature’s institutions on the representational roles its members adopt? We address this question by examining the role orientation of state legislators in eight states, explaining why some legislators identify more with a trustee model of representation and others identify more with the delegate model. Using ordinal logistic regression analysis on data from a survey ...
