Comparison of Two DXA Systems, Hologic Horizon W and GE Lunar Prodigy, for Assessing Body Composition in Healthy Korean Adults [PDF]
Endocrinology and Metabolism, 2021 Background Dual-energy X-ray absorptiometry (DXA) is the most widely used method for evaluating muscle masses. The aim of this study was to investigate the agreement between muscle mass values assessed by two different DXA systems.

Frontiers in Physics, 2021 In this work, we postulate that Schwinger’s threshold for a dynamic electric field intensity to induce spatial nonlinearity is a special case and, more generally, it is the threshold field for both static and dynamic electric fields.

Photon albedo coefficients as functions of μ/Zeff parameter [PDF]
Nuclear Technology and Radiation Protection, 2013 This paper presents the results of the analyses of photon reflection from planar targets for normal photon incidence and for different shielding materials (water, concrete, aluminum, iron, and copper), in the range of the initial photon energies from ...

A semiclassical approach reproducing asymptotically the Heitler formula for atomic photoionization
Учёные записки Казанского университета: Серия Физико-математические науки, 2020 The wave-corpuscle method for description of atomic photoionization by a flux of photons in the visible and X-ray range was developed and applied. Using the calculated photoionization probability in the asymptotics, we obtained the desired approximate ...

Single-photon microwave photonics
Science Bulletin, 2022 With the rapid development of microwave photonics technology, high-speed processing and ultra-weak signal detection capability have become the main bottlenecks in many applications. Thanks to the ultra-weak signal detection capability and the extremely low timing jitter properties of single-photon detectors, the combination of single-photon detection ...

VIRTUAL PHOTON–PHOTON SCATTERING [PDF]
International Journal of Modern Physics: Conference Series, 2014 Based on analyticity, unitarity, and Lorentz invariance the contribution from hadronic vacuum polarization to the anomalous magnetic moment of the muon is directly related to the cross section of e + e − → hadrons .
