    This study was undertaken to examine the operation of the United States Court of Military Appeals, and the effects of that Court\u27s decisions upon military justice in the armed services. Of particular interest was the Court\u27s concern for safeguarding the constitutional rights of military personnel. Extensive study of cases revealed an improving trend in the administration of military justice at the trial and investigative level and an increasing concern at all command levels for fairness and impartiality in military judicial proceedings. Study of congressional hearings on constitutional rights of military personnel confirmed that there has been remarkable progress from the ancient condition of military servitude to the modern position of recognition of the serviceman as an individual citizen. From the results of this study, it is apparent that the Uniform Code of Military Justice provides protections for an accused serviceman, that are equal to and in many regards superior to civilian systems of justice. Furthermore, the United States Court of Military Appeals, through its painstaking dedication to protect those accused of crime, has had a profound effect on the quality of military justice

    Instability of a two-dimensional extremal black hole

    We consider the perturbation of tachyon about the extremal ground state of a two-dimensional (2D) electrically charged black hole. It is found that the presenting potential to on-coming tachyonic wave takes a double-humped barrier well. This allows an exponentially growing mode with respect to time. This extremal ground state is classically unstable. We conclude that the 2D extremal electrically charged black hole cannot be a candidate for the stable endpoint of the Hawking evaporation.Comment: 9 pages 2 figures, RevTeX, to be published in Phys.

    High Energy Quark-Antiquark Elastic scattering with Mesonic Exchange

    Full text link
    We studies the high energy elastic scattering of quark anti-quark with an exchange of a mesonic state in the tt channel with −t/Λ2≫1-t/\Lambda^{2} \gg 1. Both the normalization factor and the Regge trajectory can be calculated in PQCD in cases of fixed (non-running) and running coupling constant. The dependence of the Regge trajectory on the coupling constant is highly non-linear and the trajectory is of order of 0.20.2 in the interesting physical range.Comment: 29 page

    Hip fracture, mortality risk, and cause of death over two decades

    Summary: Men and women with hip fracture have higher short-term mortality. This study investigated mortality risk over two decades post-fracture; excess mortality remained high in women up to 10 years and in men up to 20 years. Cardiovascular disease (CVD) and pneumonia were leading causes of death with a long-term doubling of risk. Introduction: Hip fractures are associated with increased mortality, particularly short term. In this study with a two-decade follow-up, we examined mortality and cause of death compared to the background population. Methods: We followed 1013 hip fracture patients and 2026 matched community controls for 22 years. Mortality, excess mortality, and cause of death were analyzed and stratified for age and sex. Hazard ratio (HR) was estimated by Cox regression. A competing risk model was fitted to estimate HR for common causes of death (CVD, cancer, pneumonia) in the short and long term (>1 year). Results: For both sexes and at all ages, mortality was higher in hip fracture patients across the observation period with men losing most life years (p <0.001). Mortality risk was higher for up to 15 years (women (risk ratio (RR) 1.9 [95 % confidence interval (CI) 1.7–2.1]); men (RR 2.8 [2.2–3.5])) and until end of follow-up ((RR 1.8 [1.6–2.0]); (RR 2.7 [2.1–3.3])). Excess mortality by time intervals, censored for the first year, was evident in women (80 years, for 5 years) and in me

    Entropy of Extremal Black Holes in Two Dimensions

    Full text link
    Entropy for two dimensional extremal black holes is computed explicitly in a finite-space formulation of the black hole thermodynamics and is shown to be zero {\it locally}. Our results are in conformity with the recent one by Hawking et al in four dimensions.Comment: 11 page

    Consequence of Hawking radiation from 2d dilaton black holes

    Get PDF
    We investigate the CGHS model through numerical calculation. The behavior of the mass function, which we introduced in our previous work as a ``local mass'', is examined. We found that the mass function takes negative values, which means that the amount of Hawking radiation becomes greater than the initial mass of the black hole as in the case of the RST model.Comment: 17pages, 5 figures (three of them are attached, the other 2 figures are available on request.

    Simvastatin is associated with superior lipid and glycaemic control to atorvastatin and reduced levels of incident Type 2 diabetes, in men and women, in the UK Biobank

    INTRODUCTION: Cardiovascular disease (CVD) is the leading cause of mortality in people with Type 2 diabetes mellitus (T2DM). Statins reduce low‐density lipoproteins and positively affect CVD outcomes. Statin type and dose have differential effects on glycaemia and risk of incident T2DM; however, the impact of gender, and of individual drugs within the statin class, remains unclear. AIM: To compare effects of simvastatin and atorvastatin on lipid and glycaemic control in men and women with and without T2DM, and their association with incident T2DM. METHODS: The effect of simvastatin and atorvastatin on lipid and glycaemic control was assessed in the T2DM DiaStrat cohort. Prescribed medications, gender, age, BMI, diabetes duration, blood lipid profile and HbA1c were extracted from Electronic Care Record, and compared in men and women prescribed simvastatin and atorvastatin. Analyses were replicated in the UKBiobank in those with and without T2DM. The association of simvastatin and atorvastatin with incident T2DM was also investigated in the UKBiobank. Cohorts where matched for age, BMI and diabetes duration in men and women, in the UKBioBank analysis, where possible. RESULTS: Simvastatin was associated with better LDL (1.6 ± 0.6 vs 2.1 ± 0.9 mmol/L, p < .01) and total cholesterol (3.6 ± 0.7 vs 4.2 ± 1.0 mmol/L, p < .05), and glycaemic control (62 ± 17 vs 67 ± 19 mmol/mol, p < .059) than atorvastatin specifically in women in the DiaStrat cohort. In the UKBiobank, both men and women prescribed simvastatin had better LDL (Women: 2.6 ± 0.6 vs 2.6 ± 0.7 mmol/L, p < .05; Men: 2.4 ± 0.6 vs 2.4 ± 0.6, p < .01) and glycaemic control (Women:54 ± 14 vs 56 ± 15mmol/mol, p < .05; Men, 54 ± 14 vs 55 ± 15 mmol/mol, p < .01) than those prescribed atorvastatin. Simvastatin was also associated with reduced risk of incident T2DM in both men and women (p < .0001) in the UKBiobank. CONCLUSIONS: Simvastatin is associated with superior lipid and glycaemic control to atorvastatin in those with and without T2DM, and with fewer incident T2DM cases. Given the importance of lipid and glycaemic control in preventing secondary complications of T2DM, these findings may help inform prescribing practices

    Radiative Kaon Decays K±→π±π0ÎłK^\pm\to\pi^\pm\pi^0\gamma and Direct CP Violation

    Full text link
    It is stressed that a measurement of the electric dipole amplitude for direct photon emission in \kpm decays through its interference with inner bremsstrahlung is important for differentiating among various models. Effects of amplitude CP violation in the radiative decays of the charged kaon are analyzed in the Standard Model in conjunction with the large NcN_c approach. We point out that gluon and electromagnetic penguin contributions to the CP-violating asymmetry between the Dalitz plots of \kpm are of equal weight. The magnitude of CP asymmetry ranges from 2×10−62\times 10^{-6} to 1×10−51\times 10^{-5} when the photon energy in the kaon rest frame varies from 50 MeV to 170 MeV.Comment: Latex, 11 pages, ITP-SB-93-36, IP-ASTP-22-9
