About Cosmic Ray Modulation in the Heliosphere

open access: yesUniverse, 2022
Cosmic ray fluxes in the heliosphere are modulated by solar wind with an embedded solar interplanetary magnetic field. The solar activity changes with a period of ~11 year, and this is the main reason for the observed 11-year variations of cosmic ray ...

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 ...

Vacuum Spin LED: First Step towards Vacuum Semiconductor Spintronics

open access: yesNanomaterials, 2023
Improving the efficiency of spin generation, injection, and detection remains a key challenge for semiconductor spintronics. Electrical injection and optical orientation are two methods of creating spin polarization in semiconductors, which traditionally

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.

Counting electrons in electrides [PDF]

open access: yes, 2023
The wave nature of electrons makes the quantification of charge fundamentally challenging. In complex materials like electrides, this challenge is amplified by the small charge and complex shape of electride wavefunctions.

Correlated Electron Transport in Molecular Electronics [PDF]

open access: yesPhysical Review Letters, 2004
Theoretical and experimental values to date for the resistances of single molecules commonly disagree by orders of magnitude. By reformulating the transport problem using boundary conditions suitable for correlated many-electron systems, we approach electron transport across molecules from a new standpoint.

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;
