Physical Activity is Related to Mental Health and Sexual Orientation Among Women in College
International Journal of Exercise Science 15(5): 1347-1356, 2022. Non-heterosexual women tend to report lower physical activity and poorer mental health than their heterosexual counterparts. The purpose of this study was to examine differences in mental health (stress and depression) and physical activity among female college students by sexual orientation. Students self-reported socio-demographic characteristics, physical activity, perceived stress, and depressive symptoms via an online survey. Correlations, independent samples t-tests, and multiple regression analyses were used to examine relationships between perceived stress, depressive symptoms, physical activity, and sexual orientation. Most participants (n = 1072, 20.0 ± 1.5 years) identified as heterosexual (90.1%), non-Hispanic White (73%), and in their fourth semester or higher. Perceived stress and depressive symptoms differed significantly between heterosexual and non- heterosexual women, but physical activity participation did not. Higher participation in vigorous physical activity and strength training predicted both lower depressive symptoms and lower perceived stress while controlling for sexual orientation. For both heterosexual and non-heterosexual sexual women, depressive symptoms had a positive relationship with perceived stress, and a negative relationship to strength training. Depressive symptoms also had negative correlations with vigorous physical activity among heterosexual women. Findings indicate non-heterosexual women experience greater perceived stress and depressive symptoms, and these mental health issues can have multi-level implications. Greater vigorous physical activity and strength training were associated with lower perceived stress and depression regardless of sexual orientation. Administrators and health promoters should consider ways to promote these forms of physical activity among non-heterosexual women. Further research is needed on the potential barriers impacting engagement in physical activity
Restricted Supergauge invariance, N=2 Coadjoint Orbit and N=2 Quantum Supergravity
It is shown that the N=2 superconformal transformations are restricted N=1
supergauge transformations of a supergauge theory with Osp(2,2) as a gauge
group. Based on this result, a canonical derivation of the Osp(2,2) current
algebra in the superchiral gauge formulation of N=2 supergravity is presented.Comment: 20 page
Search for the Proton Decay Mode proton to neutrino K+ in Soudan 2
We have searched for the proton decay mode proton to neutrino K+ using the
one-kiloton Soudan 2 high resolution calorimeter. Contained events obtained
from a 3.56 kiloton-year fiducial exposure through June 1997 are examined for
occurrence of a visible K+ track which decays at rest into mu+ nu or pi+ pi0.
We found one candidate event consistent with background, yielding a limit,
tau/B > 4.3 10^{31} years at 90% CL with no background subtraction.Comment: 13 pages, Latex, 3 tables and 3 figures, Accepted by Physics Letters
Healthcare-associated infections among patients in a large burn intensive care unit: Incidence and pathogens, 2008–2012
Burn injuries are a common source of morbidity and mortality in the United States, with an estimated 450,000 burn injuries requiring medical treatment, 40,000 requiring hospitalization, and 3,400 deaths from burns annually in the United States. Patients with severe burns are at high risk for local and systemic infections. Furthermore, burn patients are immunosuppressed, as thermal injury results in less phagocytic activity and lymphokine production by macrophages. In recent years, multidrug-resistant (MDR) pathogens have become major contributors to morbidity and mortality in burn patients

Heavy Quarks and Heavy Quarkonia as Tests of Thermalization
We present here a brief summary of new results on heavy quarks and heavy
quarkonia from the PHENIX experiment as presented at the "Quark Gluon Plasma
Thermalization" Workshop in Vienna, Austria in August 2005, directly following
the International Quark Matter Conference in Hungary.Comment: 8 pages, 5 figures, Quark Gluon Plasma Thermalization Workshop

Proximity effect at superconducting Sn-Bi2Se3 interface
We have investigated the conductance spectra of Sn-Bi2Se3 interface junctions
down to 250 mK and in different magnetic fields. A number of conductance
anomalies were observed below the superconducting transition temperature of Sn,
including a small gap different from that of Sn, and a zero-bias conductance
peak growing up at lower temperatures. We discussed the possible origins of the
smaller gap and the zero-bias conductance peak. These phenomena support that a
proximity-effect-induced chiral superconducting phase is formed at the
interface between the superconducting Sn and the strong spin-orbit coupling
material Bi2Se3.Comment: 7 pages, 8 figure
Centrality Dependence of the High p_T Charged Hadron Suppression in Au+Au collisions at sqrt(s_NN) = 130 GeV
PHENIX has measured the centrality dependence of charged hadron p_T spectra
from central Au+Au collisions at sqrt(s_NN)=130 GeV. The truncated mean p_T
decreases with centrality for p_T > 2 GeV/c, indicating an apparent reduction
of the contribution from hard scattering to high p_T hadron production. For
central collisions the yield at high p_T is shown to be suppressed compared to
binary nucleon-nucleon collision scaling of p+p data. This suppression is
monotonically increasing with centrality, but most of the change occurs below
30% centrality, i.e. for collisions with less than about 140 participating
nucleons. The observed p_T and centrality dependence is consistent with the
particle production predicted by models including hard scattering and
subsequent energy loss of the scattered partons in the dense matter created in
the collisions.Comment: 7 pages text, LaTeX, 6 figures, 2 tables, 307 authors, resubmitted to

Single Electrons from Heavy Flavor Decays in p+p Collisions at sqrt(s) = 200 GeV
The invariant differential cross section for inclusive electron production in
p+p collisions at sqrt(s) = 200 GeV has been measured by the PHENIX experiment
at the Relativistic Heavy Ion Collider over the transverse momentum range $0.4
<= p_T <= 5.0 GeV/c at midrapidity (eta <= 0.35). The contribution to the
inclusive electron spectrum from semileptonic decays of hadrons carrying heavy
flavor, i.e. charm quarks or, at high p_T, bottom quarks, is determined via
three independent methods. The resulting electron spectrum from heavy flavor
decays is compared to recent leading and next-to-leading order perturbative QCD
calculations. The total cross section of charm quark-antiquark pair production
is determined as sigma_(c c^bar) = 0.92 +/- 0.15 (stat.) +- 0.54 (sys.) mb.Comment: 329 authors, 6 pages text, 3 figures. Submitted to Phys. Rev. Lett.
