Solving Systems of Random Quadratic Equations via Truncated Amplitude Flow [PDF]
IEEE Transactions on Information Theory, 2016 This paper presents a new algorithm, termed truncated amplitude flow (TAF), to recover an unknown vector $ {x}$ from a system of quadratic equations of the form $y_{i}=|\langle {a}_{i}, {x}\rangle |^{2}$ , where $ {a}_{i}$ ’s are given random ...

Waveforms from amplitudes [PDF]
Physical Review D, 2022 We show how to compute classical wave observables using quantum scattering amplitudes. We discuss observables both with incoming and with outgoing waves. The required classical limits are naturally described by coherent states of massless bosons.

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 ...

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 ...
