News stories of gun violence have ignited the debate about what public health measures are appropriate for reducing the epidemic of gun injury and death. Although critics of stricter gun policies cite data showing stable rates of gun-related homicide over the past decade, these statistics ignore the increased rate of shootings and that improved trauma care has stabilized the death rate.1 With t...
The next generation light sources such as energy recovery linac (ERL) light sources and X-ray FEL oscillator require high brightness electron gun with megahertz repetition rate. We have developed a DC photoemission electron gun at JAEA for the Japanese ERL light source project. This DC gun employs a segmented insulator with guard rings to protect the insulator from field emission generated from...
In addition to the two monomer subunits of chicken brain-type creatine kinase (B-CK, EC, 2.7.3.2), termed Bb (basic) and Ba (acidic), another subspecies called Bb* was identified by chromatofocussing in the presence of 8 M urea (Quest et al., ). The latter low abundance protein species, isolated from tissue extracts, comigrated on 2D-gels with three minor species (Bb1-3), initially identified i...
Abstract In view of the fuzziness and uncertainty combat effectiveness evaluation index small bore naval gun, combined with AHP fuzzy method, method gun is studied. Firstly, main influencing factors are analyzed, system established. Then, based on theory, a model Finally, an example given to evaluate gun. This can effectively unify qualitative quantitative indexes in indexes, provide effective ...
A preclinical study demonstrated anti-proliferative and apoptotic effect of propranolol on multiple myeloma (MM) cell. Clinical studies suggested that beta-blocker (BB) might impact the prognosis of breast, prostate, colorectal, ovarian, lung, and skin cancer. This retrospective study evaluated the effect of BB in MM disease-specific survival (DSS) and overall survival (OS). Among 1,971 newly d...
Suicide rates are higher among those who own a handgun and among those who [corrected] live in a household with a hand gun. This article examines the association between [corrected] gun ownership and mental health, another risk factor for suicide. Data from the General Social Survey, a series of surveys of U.S. adults, are analyzed to compare general emotional and mental health, sadness and dep...
A number of jurisdictions have been experimenting with new problem-oriented policing frameworks to understand and respond to gun violence among gang-involved offenders. These interventions are based on the “pulling levers” deterrence strategy that focuses criminal justice and social service attention on a small number of chronically offending gang members responsible for the bulk of urban gun v...
The X-Band Test Area (XTA) is being assembled in the NLCTA tunnel at SLAC to serve as a test facility for new RF guns. The first gun to be tested will be an upgraded version of the 5.6 cell, 200 MV/m peak field Xband gun designed at SLAC in 2003 for the Compton Scattering experiment run in ASTA [1]. This new version includes some features implemented in 2006 on the LCLS gun such as racetrack co...
A random sample of more than 10,000 undergraduate students, selected from 119 4-year colleges, answered a mailed questionnaire about gun possession and gun threats. Approximately 4.3% of the students reported that they had a working firearm at college, and 1.6% of them have been threatened with a gun while at school. Students are more likely to have a firearm at college and to be threatened wit...
