UNLABELLED The purpose of this study was to describe antecedents and characteristics of same level fall injuries. Fall incidents and costs were compiled from the Bureau of Labor Statistics and other sources from 2006-2010. This study indicated that over 29% of 'fall on same level' injuries resulted in 31 or more workdays lost. The major source of injury was 'floors, walkways or ground surfaces'...

Incision of the Colorado River in the Grand Canyon, widely thought to have happened between ca. 6 and 1.2 Ma, has continued at variable rates along the canyon over the past ;500 k.y., based on measurements of bedrock incision combined with U-series and 40Ar/ 39Ar ages. River incision rates downstream of the Toroweap fault in the western Grand Canyon are about half the ;140 m/m.y. incision rate ...

The semileptonic CP asymmetry in B-B̄ mixing, asl, is measured in proton-proton collision data, corresponding to an integrated luminosity of 3.0 fb−1, recorded by the LHCb experiment. Semileptonic B decays are reconstructed in the inclusive final states D−μþ and D −μþ, where the D− meson decays into theKþπ−π− final state and theD − meson into the D̄0ð→ Kþπ−Þπ− final state. The asymmetry between t...

In this paper we compute the radiation of the massless closed string states due to the non-vanishing coupling to the rolling open string tachyon with co-dimensions larger than 3, and discuss the effect of back reaction to the motion of the rolling tachyon. We find that for small string coupling, the tachyonic matters remain in the late time, but it will completely evaporate away over a string s...

The light quarks inside B mesons are usually treated as spectators and do not affect the decay rates which are assumed to be purely due to b quark decays. In this paper we calculate the non-spectator contributions to inclusive charmless B decays due to the spectator effects. We find that the non-spectator contributions to the branching ratio for B̄ are small (< 2 × 10), but the contributions to ...

In the decay of Υ(4S), the decay time distribution of Υ(4S) → f + X, where f is a final state that both B and B 0 can decay to, is the sum of the decay time distributions of B → f and B → f . Using this general rule, we estimate the sensitivity of single lepton CP violation measurements with respect to that of traditional di-lepton measurements. We find that the sensitivity of the single lepton...
