Electrically Tunable Metasurface with Independent Frequency and Amplitude Modulations
, 2020 Metasurfaces with actively tunable features are highly demanded for advanced applications in electronic and electromagnetic systems. However, realizing independent dual-tunability remains challenging and requires more efforts.

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.

Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2015 A brief review is given of why twistor geometry has taken a central place in the theory of scattering amplitudes for fundamental particles. The emphasis is on the twistor diagram formalism as originally proposed by Penrose, the development of which has now led to the definition by Arkani-Hamedet al.of the ‘amplituhedron’.

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.

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.

Complete amplitude and phase control of light using broadband holographic metasurfaces. [PDF]
Nanoscale, 2017 Reconstruction of light profiles with amplitude and phase information, called holography, is an attractive optical technology with various significant applications such as three-dimensional imaging and optical data storage.

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 ...

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.
