Amy Berning served as the project's Contracting Officer's Technical Representative. The National Institute on Alcohol Abuse and Alcoholism (NIAAA) provided funding and support for the assessment of alcohol use disorders. The National Institute on Drug Abuse (NIDA) provided funding for the collection of additional blood samples and the administration of the drug use disorders assessment. The National Institute of Justice (NIJ) provided support for querying participants about interaction with the criminal justice system. AbstractThis report presents the first national prevalence estimates for drug-involved driving derived from the recently completed 2007 National Roadside Survey (NRS). The NRS is a national field survey of alcohol-and drug-involved driving conducted primarily among nighttime weekend drivers, but also daytime Friday drivers. The survey involved randomly stopping drivers at 300 locations across the continental United States; sites were selected through a stratified random sampling procedure. This included data that we collected during a two-hour Friday daytime session at 60 locations and during four 2-hour nighttime periods (10 p.m. to midnight and 1 a.m. to 3 a.m. on both Friday and Saturday) at 240 locations. Both self-report and biological measures were taken. Biological measures included breath alcohol measurements on 9,413 respondents, oral fluid from 7,719 respondents, and blood samples from 3,276 respondents. Oral fluid and blood samples were subjected to laboratory screening and LC/MS-MS and GC/MS confirmation for 75 drugs and metabolites, including illegal, prescription, and over-the-counter drugs. These data were analyzed to develop the first national prevalence estimate of alcohol-and drug-involved driving. Two prior reports on the 2007 NRS described: (1) the sampling plan and data collection methodology, summarizing the response patterns to the various stages of the multi-part survey; and (2) the prevalence estimates for alcohol-involved driving derived from the study, and comparing them with the three previous National Roadside Surveys (NRS). iii AcknowledgementsThe authors received extensive assistance from State and local officials in the conduct of this project. Our data collection procedures were not routine. The willingness of officials to help us identify cooperating local law enforcement agencies and the willingness of agencies to participate in the project were essential to our success.

MethodologyThree prior national roadside surveys of drivers to estimate prevalence of drinking and driving and determine changes over time have been conducted in the United States. These surveys, which included a brief interview and a breath sample to determine blood alcohol concentration (BAC), were conducted on a s...

Future liquid-argon DarkSide-20k and Argo detectors, designed for direct dark matter search, will be sensitive also to core-collapse supernova neutrinos, via coherent elastic neutrino-nucleus scattering. This interaction channel is flavor-insensitive with a high-cross section, enabling for a high-statistics neutrino detection with target masses of ∼50 t and ∼360 t for DarkSide-20k and Argo respectively. Thanks to the low-energy threshold of ∼0.5 keV nr achievable by exploiting the ionization channel, DarkSide-20k and Argo have the potential to discover supernova bursts throughout our galaxy and up to the Small Magellanic Cloud, respectively, assuming a 11-M progenitor star. We report also on the sensitivity to the neutronization burst, whose electron neutrino flux is suppressed by oscillations when detected via charged current and elastic scattering. Finally, the accuracies in the reconstruction of the average and total neutrino energy in the different phases of the supernova burst, as well as its time profile, are also discussed, taking into account the expected background and the detector response.

Excited states in 58,60,62 Ni were populated via inelastic proton scattering at the Australian National University as well as via inelastic neutron scattering at the University of Kentucky Accelerator Laboratory. The Super-e electron spectrometer and the CAESAR Compton-suppressed HPGe array were used in complementary experiments to measure conversion coefficients and δ(E2/M 1) mixing ratios, respectively, for a number of 2 + → 2 + transitions. The data obtained were combined with lifetimes and branching ratios to determine E0, M 1, and E2 transition strengths between 2 + states. The E0 transition strengths between 0 + states were measured using internal conversion electron spectroscopy and compare well to previous results from internal pair formation spectroscopy. The E0 transition strengths between the lowest-lying 2 + states were found to be consistently large for the isotopes studied.

The level structures of 130,132 Xe were studied with the inelastic neutron scattering reaction followed by γ-ray detection. Level lifetimes were measured using the Doppler-shift attenuation method and low-lying excited states in these nuclei were characterized. With a focus on the decay properties of the 0 + states, these nuclei were examined as representations of the E(5) critical-point symmetry.

Double differential cross sections of neutrons from d + 63,65 Cu reactions have been measured at deuteron energies of 6 and 7.5 MeV. The cross sections measured at backward angles have been compared to theoretical calculations in the framework of the statistical Hauser-Feshbach model. Three different level density models were tested: the Fermi-gas model, the Gilbert-Cameron model, and the microscopic approach through the Hartree-Fock-Bogoliubov method (HFBM). The calculations using the Gilbert-Cameron model are in best agreement with our experimental data. Level densities of the residual nuclei 64 Zn and 66 Zn have been obtained from statistical neutron evaporation spectra. The angle-integrated cross sections have been analyzed with the exciton model of nuclear reaction.
