Amplitude dependence of image quality in atomically-resolved bimodal atomic microscopy [PDF]

, 2016
In bimodal FM-AFM, two flexural modes are excited simultaneously. The total vertical oscillation deflection range of the tip is the sum of the peak-to-peak amplitudes of both flexural modes (sum amplitude).

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

Consensus for experimental design in electromyography (CEDE) project: Amplitude normalization matrix.

Journal of Electromyography & Kinesiology, 2020
The general purpose of normalization of EMG amplitude is to enable comparisons between participants, muscles, measurement sessions or electrode positions.

Tropical Amplitudes [PDF]

Annales Henri Poincaré, 2017
In this work, we argue that the α′→0 limit of closed string theory scattering amplitudes is a tropical limit. The motivation is to develop a technology to systematize the extraction of Feynman graphs from string theory amplitudes at higher genus.

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.

Model selection for amplitude analysis [PDF]

, 2015
Model complexity in amplitude analyses is often a priori under-constrained since the underlying theory permits a large number of possible amplitudes to contribute to most physical processes.

DYNAMIC AND MATHEMATICAL MODELS OF THE HYDROIMPULSIVE VIBRO-CUTTING DEVICE WITH A PRESSURE PULSE GENERATOR BULT INTO THE RING SPRING

Informatyka, Automatyka, Pomiary w Gospodarce i Ochronie Środowiska, 2022
Structural calculation scheme of the hydropulse device for vibration cutting with built-in ring with pressure pulse generator (PPG) is considered. On the basis of the structural scheme and cyclogram of the working cycle of the device, its dynamic and ...

Shadow celestial amplitudes

Journal of High Energy Physics, 2023
Abstract We study scattering amplitudes in the shadow conformal primary basis, which satisfies the same defining properties as the original conformal primary basis and has many advantages over it. The shadow celestial amplitudes exhibit locality manifestly on the celestial sphere, and behave like correlation functions in conformal ...

The Variation of the Linewidths and Amplitudes of Sub-Doppler Resonances of 87Rb D2 Line with Laser Beam Intensity

Sakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2022
The sub-Doppler resonances linewidths and amplitudes depend on the laser beam intensity. The effect of laser beam intensity on the resonance linewidths and amplitudes obtained from different energy transitions of atoms varies from resonance to resonance.

Scattering amplitude annihilators

, 2020
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.Comment: 31 ...
