Learning cellular morphology with neural networks
Nature 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 ...

About Cosmic Ray Modulation in the Heliosphere
Universe, 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 ...

Counting electrons in electrides [PDF]
, 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.

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

Correlated Electron Transport in Molecular Electronics [PDF]
Physical 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.

Surfatron and stochastic acceleration of electrons in astrophysical plasmas [PDF]
, 2005 Electron acceleration by large amplitude electrostatic waves in astrophysical plasmas is studied using particle-in-cell (PIC) simulations. The waves are excited initially at the electron plasma frequency $\omega_{\rm pe}$ by a Buneman instability driven ...

Electron loss rates from the outer radiation belt caused by the filling of the outer plasmasphere: The calm before the storm [PDF]
, 2009 Measurements from seven spacecraft in geosynchronous orbit are analyzed to determine the decay rate of the number density of the outer electron radiation belt prior to the onset of high-speed-stream-driven geomagnetic storms.
