STATISTIC OF SEASONAL AND DIURNAL VARIATIONS OF DOPPLER FREQUENCY SHIFT OF HF SIGNALS AT MID-LATITUDE RADIO PATH [PDF]

Radio Physics and Radio Astronomy, 2020
Purpose: An experimental study of signatures of traveling ionospheric disturbances (TID) observed in diurnal-seasonal variations of the parameters of probe HF signals propagating on theoblique single-hop RWM–LFO radio path, derived from the yearlong ...

Algebras for amplitudes [PDF]

Journal of High Energy Physics, 2012
Abstract Tree-level amplitudes of gauge theories are expressed in a basis of auxiliary amplitudes with only cubic vertices. The vertices in this formalism are explicitly factorized in color and kinematics, clarifying the color-kinematics duality in gauge theory amplitudes.

Normative values of visual evoked potential in adults

Indian Journal of Ophthalmology, 2021
Purpose: Visual evoked potentials (VEP) are used to determine the function of visual pathway from the optic nerve to visual cortex. Various factors may affect VEP response, viz., technical and environmental.

Experimental demonstration of a temporal pulse shaping method based on nonlinear chirp [PDF]

EPJ Web of Conferences
We present a general temporal shaping method based on spectral phase-only modulation for ultrafast laser sources. We explain the working principle of this technique and use it experimentally to generate a ramp-shaped pulse at the output of a laser source

Comparison of Propofol and Ketofol on Transcranial Motor Evoked Potentials in Patients Undergoing Thoracolumbar Spine Surgery [PDF]

Asian Spine Journal, 2022
Study Design This was a double-blind randomized study. Purpose The primary purpose was to compare the effects of propofol and ketofol on amplitudes and latencies of transcranial motor evoked potentials (TcMEPs) during thoracolumbar spine surgery.

A course in amplitudes [PDF]

Physics Reports, 2017
This a pedagogical introduction to scattering amplitudes in gauge theories. It proceeds from Dirac equation and Weyl fermions to the two pivot points of current developments: the recursion relations of Britto, Cachazo, Feng and Witten, and the unitarity cut method pioneered by Bern, Dixon, Dunbar and Kosower.
