Scattering amplitude annihilators [PDF]
Journal of High Energy Physics, 2020 Abstract Several second order differential operators are shown to annihilate the YM and GR tree scattering amplitudes. In particular we prove a conjecture of Loebbert, Mojaza and Plefka from their investigation of a hidden conformal symmetry in GR.

Quantum Amplitude Amplification and Estimation [PDF]
, 2000 Consider a Boolean function $\chi: X \to \{0,1\}$ that partitions set $X$ between its good and bad elements, where $x$ is good if $\chi(x)=1$ and bad otherwise. Consider also a quantum algorithm $\mathcal A$ such that $A |0\rangle= \sum_{x\in X} \alpha_x

Spinning amplitudes from scalar amplitudes [PDF]
Journal of High Energy Physics, 2021 AbstractWe provide a systematic method to compute tree-level scattering amplitudes with spinning external states from amplitudes with scalar external states in arbitrary spacetime dimensions. We write down analytic answers for various scattering amplitudes, including the four graviton amplitude due to the massive spinJexchange. We verify the results by

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.

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.

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.

Amplitude estimation without phase estimation [PDF]
Quantum Information Processing, 2019 This paper focuses on the quantum amplitude estimation algorithm, which is a core subroutine in quantum computation for various applications. The conventional approach for amplitude estimation is to use the phase estimation algorithm, which consists of ...

Effect of Umbilical Cord Ferritin Level on Auditory Brainstem Response Threshold in Newborns [PDF]
Iranian Journal of Otorhinolaryngology, 2020 Introduction: Iron plays an important role in myelination. Ferritin is a reliable indicator of the tissue iron store and umbilical cord ferritin level reflects the in utero iron stores.

Recovery of harmonic signal from discrete samples
Adaptivni Sistemi Avtomatičnogo Upravlinnâ, 2021 The change–over from direct analog methods of measuring signal parameters to digital methods based on the use of analog–to–digital conversion (ADC) and microprocessor devices can be promising in the construction of various sensors.
