Pitch-Tracking Metrics as a Predictor of Future Shoulder and Elbow Injuries in Major League Baseball Pitchers: A Machine-Learning and Game-Theory Based Analysis.

Background: Understanding interactions between multiple risk factors for shoulder and elbow injuries in Major League Baseball (MLB) pitchers is important to identify potential avenues by which risk can be reduced while minimizing impact on player performance.

Purpose: To apply a novel game theory-based approach to develop a machine-learning model predictive of next-season shoulder and elbow injuries in MLB pitchers and use this model to understand interdependencies and interaction effects between the most important risk factors.

Study Design: Case-control study; Level of evidence, 3.

Decreasing expression of the interleukin-13 receptor IL-13Ralpha2 in treated recurrent malignant gliomas.

The IL-13Ralpha2 gene encodes for a 65 kDa protein that forms one of the subunits of the interleukin-13 (IL-13) receptor. This gene is highly expressed in various types of human tumors including malignant gliomas. The expression level of IL-13Ralpha2 was examined in a total of 45 tissue samples of anaplastic astrocytomas (AAs) World Health Organization (WHO) grade III, glioblastomas (GBMs) WHO grade IV, and first-recurrent glioblastomas (frGBMs) after treatment with radiation and chemotherapy.

Search for charged higgs bosons decaying into top and bottom quarks in pp[over ] collisions.

We describe a search for production of a charged Higgs boson, qq[over ];{'}-->H;{+}, reconstructed in the tb[over ] final state in the mass range 180< or =M_{H;{+}}< or =300 GeV. The search was undertaken at the Fermilab Tevatron collider with a center-of-mass energy sqrt[s]=1.96 TeV and uses 0.

Measurement of the lifetime of the Bc+/- meson in the semileptonic decay channel.

Using approximately 1.3 fb(-1) of data collected by the D0 detector between 2002 and 2006, we measure the lifetime of the Bc+/- meson in the Bc-/+-->J/psimicro+/-+X final state. A simultaneous unbinned likelihood fit to the J/psi+micro invariant mass and lifetime distributions yields a signal of 881+/-80(stat) candidates and a lifetime measurement of tau(Bc+/-)=0.

Search for associated W and Higgs Boson production in pp[over ] collisions at sqrt[s]=1.96 TeV.

We present results of a search for WH-->lnubb[over ] production in pp[over ] collisions based on the analysis of 1.05 fb;{-1} of data collected by the D0 experiment at the Fermilab Tevatron, using a neural network for separating the signal from backgrounds. No signal-like excess is observed, and we set 95% C.
