objectives: the purpose of this study was to compare scapular kinematics during elevation phase of abduction, flexion, and scapular plane elevation phase between fifteen persons with shoulder impingement syndrome (sis) and thirteen persons without it. methods: values of scapular kinematics include scapular superior and lateral translations, upward rotation, external rotation, and posterior tipp...

We use the perturbative QCD methods of Lepage and Brodsky, together with the current field identity, to calculate the rate for ¯ B s → ρK s , with an eye toward the CP violating unitarity triangle angle γ. We show that , although the penguins are large, there are regions of the allowed parameter space of the Cabibbo-Kobayashi-Maskawa mixing matrix wherein γ is measurable in the sense that pengu...

We show that , although the penguins are large, there are regions of the allowed parameter space of the Cabibbo-Kobayashi-Maskawa mixing matrix wherein γ is measurable in the sense that penguins change the value of sin(2γ) one would e...

We present a new method for describing the kinematics of the rotational motion of a rigid body The new kinematic formulation provides a three dimensional parameterization of the rotation group using two perpendicular rotations thus it complements the Eulerian angles three rotations and Euler Rodrigues parameters one rotation The di erential equations can be described by two scalar equations We ...
