Magnetic spectrum of trigonally warped bilayer graphene - semiclassical analysis, zero modes, and topological winding numbers

open access: yes, 2013
We investigate the fine structure in the energy spectrum of bilayer graphene in the presence of various stacking defaults, such as a translational or rotational mismatch.

ATP13A2 is involved in intracellular polyamine transport in lung epithelial cells

open access: yesFEBS Open Bio, EarlyView.
Spermidine transport in lung epithelial cells involves the polyamine transporter ATP13A2. Cell proliferation is associated with the upregulation of ATP13A2. Polyamines are present in all living cells and are implicated in various crucial cellular processes such as proliferation, apoptosis and autophagy.

Lassoing saddle splay and the geometrical control of topological defects

open access: yes, 2016
Systems with holes, such as colloidal handlebodies and toroidal droplets, have been studied in the nematic liquid crystal (NLC) 4-cyano-4'-pentylbiphenyl (5CB): both point and ring topological defects can occur within each hole and around the system ...

Enzymatic degradation of biopolymers in amorphous and molten states: mechanisms and applications

open access: yesFEBS Open Bio, EarlyView.
This review explains how polymer morphology and thermal state shape enzymatic degradation pathways, comparing amorphous and molten biopolymer structures. By integrating structure–reactivity principles with insights from thermodynamics and enzyme engineering, it highlights mechanisms that enable efficient polymer breakdown.

Experimental Investigation on Cumulative Effects of Transformer Winding Deformation Under Short‐Circuit Impulses

open access: yesIET Electric Power Applications
Power transformer windings are susceptible to deformation after multiple short‐circuit impulses, threatening power grid stability. Currently, there is a lack of experimental data on various characteristic parameters of failures after multiple short ...

Investigation of Stator Windings Looseness of Polyphase Induction Machine after Rewinded in Workshop: Numerical and Experimental Analysis

open access: yesMajlesi Journal of Electrical Engineering, 2022
Electric machines, particularly induction motors, are widely used in industry as they are robust in construction and require less maintenance. These machines are continuously operated under high loading conditions, which may result in machine vibrations.

Analysis of coil slumping [PDF]

open access: yes, 2009
Steel strip is usually stored as a coil, which will slump to some degree after the removal of the mandrel. More often than not, the amount of slumping is so minor that it is assumed not to have occurred.

The Relationship Between Inflammation and Central Nervous System in Multiple Sclerosis

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Aim Multiple sclerosis is an autoimmune demyelination disease that is seen especially in the young population and has a progressive course, causing motor, sensory, and cognitive deficits. In the literature, the pathogenesis of MS disease and the interconnection between the immune and central nervous system in the disease have not been fully ...
