We have measured the inclusive $b\ensuremath{\rightarrow}s\ensuremath{\gamma}$ branching ratio to be $(2.32\ifmmode\pm\else\textpm\fi{}0.57\ifmmode\pm\else\textpm\fi{}0.35)\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}4}$, where first error is statistical and second systematic. Upper lower limits on ratio, each at 95% C.L., are $B(b\ensuremath{\rightarrow}s\ensuremath{\gamma})<4.2\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}4}$...
A data-fitting method based on the whale optimization algorithm (WOA) is proposed to determine thickness and refractive index of films measured by spectroscopic ellipsometry (SE). To demonstrate this method, tin oxide (SnO2) with transparent wavelength coverage (400–800 nm) are evaluated. The comparative analysis indicates that Psi Delta parameter curves WOA fitting align more closely those obtained through experiments. Furthermore, in nearly agreement results from well-known...
We observe a narrow enhancement near 2m(p) in the invariant mass spectrum of pp pairs from radiative J/psi-->gammapp decays. No similar structure is seen J/psi-->pi(0)pp The results are based on an analysis 58 x 10(6) event sample J/psi decays accumulated with BESII detector at Beijing electron-positron collider. can be fit either S- or P-wave Breit-Wigner resonance function. In case S-wave fit, peak below M=1859(+3)(-10) (stat)+5-25(syst) MeV/c(2) and total width Gamma<30 90% confidence...
The BES experiment at the Beijing electron-positron collider has observed ξ(2230) signal in π+π−, K+K−, K0SK0S, and p¯p final states with 4.6σ, 4.1σ, 4.0σ, 3.8σ statistical significances, respectively. new observations of two nonstrange decay modes ξ→π+π− are important evidence for glueball interpretation ξ(2230).Received 30 October 1995DOI:https://doi.org/10.1103/PhysRevLett.76.3502©1996 American Physical Society
Results are presented on ψ(2S) and J/ψ hadronic decays to K0SpK−n̄ K0S¯pK+n final states from data samples of 14 million 58 events accumulated at the BES II detector.

Ocean acts as a "sink" for pollutants in the natural environment. Consequently, issues focused on marine pollution from terrestrial origin is attracting increasing attention. Persistent organic (POPs), including organochlorine pesticides (OCPs), polychlorinated biphenyls (PCBs), short-chain chlorinated paraffins (SCCPs), and dechlorane plus isomers (DPs), are serious hazards both environment humans. These POPs have been widely detected typically present at trace levels; however, separating...
Abstract Introduction Predicting discharge disposition for burn patients with large total body surface area (TBSA) is essential to optimizing care and improving long-term outcomes. Patient recovery, expectations, goal setting require early physician planning, but recovery rarely based solely on TBSA. A multidisciplinary approach, paired simple yet comprehensive assessment tools, can enhance patient discussions family preparedness. The Activity Measure Post-Acute Care Six-Clicks, a functional...
Abstract Introduction Burn injuries are some of the most severe that enter hospitals. Length stay (LOS) is often difficult to predict in these patients, and variability individual responses care makes it estimate burn recovery. mortality prediction well-established, but as survival rates rapidly increase, formulas have be readjusted. Physical therapists gauge mobility with a tool known AM-PAC 6-clicks on scale 6 24, lower scores implying worse mobility. These tools offer an interprofessional...
