Electronic Markets and Electronic Hierarchies [PDF]

open access: yesCommunications 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–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.

A semiclassical approach reproducing asymptotically the Heitler formula for atomic photoionization

open access: yesУчёные 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 ...

Recent insights into the molecular mechanism of ubiquinol oxidation by cytochrome bc<sub>1</sub>. [PDF]

open access: yesFEBS Open Bio
The review reflects on the mechanism of the catalytic reaction in cytochrome bc1: the electron bifurcation that involves the separation of two electrons derived from the quinol oxidation to opposite sides of the enzyme across the membrane. This review summarizes the long‐standing effort to understand the mechanism of quinol oxidation catalyzed by ...

Photoluminescence and thermoluminescence in a Li2SO4 crystall

open access: yesEurasian Journal of Physics and Functional Materials, 2022
The nature of intrinsic emission and the creation of electron-hole trapping centers in irradiated with ultraviolet and X-rays at 15 K and 300 K was investigated in Li2SO4 by methods of spectroscopy. It is shown that in activated Li2 SO4 with an energy of
