Some biomechanical characteristics for sprint stride and its relation to foot placement on the curve and straight for 100 and 200 m sprinters [PDF]
Assiut Journal of Sport Science and Arts, 2015 This equation allows the prediction of the angle of lean of a runner for any velocity, v, and cornering radius r. Typically for an athlete running at 10 m/s (a 200 m race) around an athletics track of radius of rotation 40 m, the angle of lean would be ...

AdS field theory from conformal field theory [PDF]
Journal of High Energy Physics, 2013 Abstract We provide necessary and sufficient conditions for a Conformal Field Theory to have a description in terms of a perturbative Effective Field Theory in AdS. The first two conditions are well-known: the existence of a perturbative ‘1/N ’ expansion and an approximate Fock space of states generated by a finite number of low ...
