Impact of Arm Length and Body Mass Index on Abductor Pollicis Brevis (APB) H-Reflex among Females [PDF]
Journal of Clinical and Diagnostic Research, 2019 Introduction: Hoffmann reflex (H-reflex) is an electrically induced reflex analogous to the mechanically induced spinal stretch reflex. H-reflex is useful clinically to diagnose nerve root lesions, particularly involving S1 radiculopathy and in proximal ...

S-duality and helicity amplitudes [PDF]
Journal of High Energy Physics, 2016 We examine interacting Abelian theories at low energies and show that holomorphically normalized photon helicity amplitudes transform into dual amplitudes under SL(2,Z) as modular forms with weights that depend on the number of positive and negative helicity photons and on the number of internal photon lines.

Unitarized pion-nucleon scattering amplitude from inverse amplitude method
, 2003 In a recent work on low energy pion-nucleon scattering, instead of using chiral perturbation theory (ChPT) amplitude, we started from a pion-nucleon {\it soft-pion} result and used elastic unitarity directly as a dynamical constraint to construct first ...
