Storm-Time Evolution of the Equatorial Electron Pitch Angle Distributions in Earth’s Outer Radiation Belt

open access: yesFrontiers in Astronomy and Space Sciences, 2022
In this study we analyze the storm-time evolution of equatorial electron pitch angle distributions (PADs) in the outer radiation belt region using observations from the Magnetic Electron Ion Spectrometer (MagEIS) instrument aboard the Van Allen Probes in

Electron–electron and electron–hole pairing in graphene structures [PDF]

open access: yesPhilosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2010
The superconducting pairing of electrons in doped graphene owing to in-plane and out-of-plane phonons is considered. It is shown that the structure of the order parameter in the valley space substantially affects conditions of the pairing. Electron–hole pairing in a graphene bilayer in the strong coupling regime is also considered.

Outcome of hypofractionated breast irradiation and intraoperative electron boost in early breast cancer: A randomized non‐inferiority clinical trial

open access: yesCancer Reports, 2021
Background Intraoperative electron radiotherapy (IOERT) followed by hypofractionated whole breast irradiation (HWBI) provides the shortest possible time of adjuvant breast irradiation. The efficacy of either method has been described in previous reports;

Learning cellular morphology with neural networks

open access: yesNature Communications, 2019
Volume electron microscopy data of brain tissue can tell us much about neural circuits, but increasingly large data sets demand automation of analysis. Here, the authors introduce cellular morphology neural networks and successfully automate a range of ...

Impact of Electron-Electron Cusp on Configuration Interaction Energies [PDF]

open access: yesJ. Chem. Phys. 115, 1626 (2001), 2001
The effect of the electron-electron cusp on the convergence of configuration interaction (CI) wave functions is examined. By analogy with the pseudopotential approach for electron-ion interactions, an effective electron-electron interaction is developed which closely reproduces the scattering of the Coulomb interaction but is smooth and finite at zero ...

Design and characterization of electrons in a fractal geometry [PDF]

open access: yesNature Physics, 2018
The dimensionality of an electronic quantum system is decisive for its properties. In one dimension, electrons form a Luttinger liquid, and in two dimensions, they exhibit the quantum Hall effect.

Endoscopic diagnosis of Whipple disease in a patient without gastrointestinal symptoms: A case report

open access: yesDEN Open, 2022
Whipple's disease is a systemic chronic bacterial infection caused by Tropheryma whipplei, a gram‐positive bacillus. T. whipplei infection in the small intestine often causes malabsorption and is often accompanied by gastrointestinal symptoms such as ...

The Sub-Molecular and Atomic Theory of Cancer Beginning: The Role of Mitochondria

open access: yesDiagnostics, 2022
Life as we know it is made of strict interaction of atom, metabolism, and genetics, made around the chemistry of the most common elements of the universe: hydrogen, oxygen, nitrogen, sulfur, phosphorus, and carbon.

Electron thermal conductivity owing to collisions between degenerate electrons [PDF]

open access: yesPhys.Rev. D74 (2006) 043004, 2006
We calculate the thermal conductivity of electrons produced by electron-electron Coulomb scattering in a strongly degenerate electron gas taking into account the Landau damping of transverse plasmons. The Landau damping strongly reduces this conductivity in the domain of ultrarelativistic electrons at temperatures below the electron plasma temperature.

ELECTRON-STIMULATED OXYGEN ADSORPTION ON THE SURFACE OF METALS AND SEMICONDUCTORS

open access: yesФизико-химические аспекты изучения кластеров, наноструктур и наноматериалов, 2019
The phenomenon of electron-stimulated adsorption occurs in almost all devices where electron emission is used. Electron-stimulated adsorption can have a significant effect on the state of the adsorbed layer.
