Space Weather Effects from Observations by Moscow University Cubesat Constellation

Universe, 2022
Moscow State University is developing a project for a multi-satellite constellation intended for the monitoring of space radiation. A number of small satellites of CubeSat format were launched into selected orbits crossing the wide range of magnetic ...

Electronic Markets and Electronic Hierarchies [PDF]

Communications of the ACM, 1987
Abstract The innovations in information technologies of the past two decades have radically reduced the time and cost of processing and communicating information. These reductions have in turn brought many changes in the ways that tasks are accomplished in firms.

Electron-acoustic_solitary_structures_in_two-electron-temperature_plasma_with_superthermal_electrons

, 2011
The propagation of nonlinear electron- acoustic waves (EAWs) in an unmagnetized collision- less plasma system consisting of a cold electron fluid, superthermal hot electrons and stationary ions is investigated. A reductive perturbation method is employed

Role of electron-electron and electron-phonon interaction effect in the optical conductivity of VO2 [PDF]

, 2006
We have investigated the charge dynamics of VO2 by optical reflectivity measurements. Optical conductivity clearly shows a metal-insulator transition. In the metallic phase, a broad Drude-like structure is observed.

Electron-electron interaction in carbon nanostructures

, 2006
The electron-electron interaction in carbon nanostructures was studied. A new method which allows to determine the electron-electron interaction constant $\lambda_c$ from the analysis of quantum correction to the magnetic susceptibility and the ...

Mapping the evolution of mitochondrial complex I through structural variation

FEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)
