Review ArticleOpen accessIn the abstractAstrocytes Store for Memory and CognitionMajid Karimi BaghmalekiIn humans, protoplasmic astrocytes are found with high density in the cortex and hippocampus (both parts responsible for memory and cognition) and each astrocyte is in contact with two million of synapses. Astrocytes are responsible for the synaptogenesis and the removal of synapses, which is the basis of learning and memory. The synaptogenesis increases sevenfold with the addition of astrocytes … …Neuroscience International, Vol. 12, Issue 1 · 21 Apr 2021 · 17,209 accessesView PDFCite
Research ArticleOpen accessIn the abstractFabrication of Ni, Si and Mg Supersaturated Solid Solutions in Al by Mechanical AlloyingA. Sedano, A. Molina, S.A. Serna et al.In this work, a comparison between the synthesis process of nanostructured Al base alloys modified with Si, Ni and Mg and the formation of their respective supersaturated solid solution is presented. The samples were obtained via Mechanical Alloying (MA) at a speed of 300 RPM for 2, 5, 10, 20 and 30 h under an inert Ar atmosphere.

Research NotesOpen accessIn the abstractA Study on Fabrication and Structural Characterization of PbS Thin FilmsMustika Wati, Kamsul AbrahaPbS thin films are fabricated from 99.9% PbS powder on glass substrates using the vacuum evaporation method. Some of the samples are then treated in an advanced process called annealing. Samples are annealed in temperatures of 80, 100, 120 and 150°C for two h. Characterization using an X-Ray Diffractometer (XRD) resulted in values of lattice constant of the films ranging … …American Journal of Biochemistry and Biotechnology, Vol. 13, Issue 4 · 20 Nov 2017 · 7,847 accessesView PDFCite
Research ArticleOpen accessIn the abstractInteraction Model in Statistical MechanicsFarida Kachapova, Ilias KachapovStatistical mechanics considers several models such as Ising model, Potts model, Heisenberg model etc. A rigorous mathematical approach based on the axiomatic foundation of probability would benefit the study and applications of these models. In this paper we use this approach to generalize some of these models into one construction named an interaction model. We introduce a mathematically rigorous definition … …Journal of Mathematics and Statistics, Vol. 13, Issue 4 · 4 Nov 2017 · 7,054 accessesView PDFCite

Research ArticleOpen accessIn the abstractConvergence of Renormalization Group Transformations of Gibbs Random FieldFarida Kachapova, Ilias KachapovStatistical mechanics describes interaction between particles of a physical system. Particle properties of the system can be modelled with a random field on a lattice and studied at different distance scales using renormalization group transformation. Here we consider a thermodynamic limit of a lattice model with weak interaction and we use semi-invariants to prove that random fields transformed by renormalization … …Journal of Mathematics and Statistics, Vol. 12, Issue 3 · 27 Jul 2016 · 7,012 accessesView PDFCite
Research ArticleOpen accessIn the abstractA General Strategy to Enhance Upconversion luminescence in Rare-Earth-Ion-Doped Oxide NanocrystalsGuanying Chen, Lei XuWe report a general strategy to enhance upconversion luminescence from rare-earth-doped oxide nanocrystals through tailoring the local crystal filed around rare earth ions. We show that upconversion luminescence from oxide nanocrystals of various host lattice (Y2O3, Gd2O3 and ZnO) and of diverse rare-earth-ions (such as Er3+, Yb3+/Er3+, Yb3+/Ho3+ and Yb3+/Tm3+) was enhanced by orders of magnitude through an introduction of … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 1 · 18 Feb 2016 · 7,735 accessesView PDFCite
Review ArticleOpen accessIn the abstractMulti-Timescale Microscopic Theory for Radiation Degradation of Electronic and Optoelectronic DevicesDanhong Huang, Fei Gao, D.A. Cardimona et al.A multi-timescale hybrid model is proposed to study microscopically the degraded performance of electronic devices, covering three individual stages of radiation effects studies, including ultra-fast displacement cascade, intermediate defect stabilization and cluster formation, as well as slow defect reaction and migration. Realistic interatomic potentials are employed in molecular-dynamics calculations for the first two stages up to 100 ns as well … …Space Science International, Vol. 3, Issue 1 · 15 Jun 2015 · 10,235 accessesView PDFCite
