Depolarization of multidomain ferroelectric materials [PDF]
Nature Communications, 2019 AbstractDepolarization in ferroelectric materials has been studied since the 1970s, albeit quasi-statically. The dynamics are described by the empirical Merz law, which gives the polarization switching time as a function of electric field, normalized to the so-called activation field.

The Stroke-Migraine Depolarization Continuum [PDF]
Neuron, 2015 The term spreading depolarization (SD) refers to waves of abrupt, sustained mass depolarization in gray matter of the CNS. SD, which spreads from neuron to neuron in affected tissue, is characterized by a rapid near-breakdown of the neuronal transmembrane ion gradients.

Fast Flavor Depolarization of Supernova Neutrinos. [PDF]
Physical Review Letters, 2020 Flavor-dependent neutrino emission is critical to the evolution of a supernova and its neutrino signal. In the dense anisotropic interior of the star, neutrino-neutrino forward scattering can lead to fast collective neutrino oscillations, which has ...

A potential biomarker of cognitive impairment: The olfactory dysfunction and its genes expression
Annals of Clinical and Translational Neurology, Volume 9, Issue 12, Page 1884-1897, December 2022., 2022 Abstract Objective Accumulation evidence has reported that olfactory impairment may be an essential clinical marker and predictor of mild cognitive impairment or Alzheimer's disease. Method Participants were enrolled in the population‐based, prospective study in Fuxin county, Liaoning province, China between 2019 and 2021.

Does long‐term phenytoin have a place in Dravet syndrome?
Annals of Clinical and Translational Neurology, Volume 9, Issue 12, Page 2036-2040, December 2022., 2022 Abstract Anti‐seizure medications that block sodium channels are generally considered contraindicated in Dravet syndrome. There is, however, considerable debate about the sodium‐channel blocker phenytoin, which is often used for status epilepticus, a frequent feature of Dravet syndrome.

Suppression of Speckle Noise in Digital Holography With Spatial and Temporal Domain Depolarization
IEEE Access, 2020 Speckle noise in digital holography has a great influence on image quality, and one of the reasons for the formation of speckle noise is that the degree of coherence for the reference light and the object light is too high and unnecessary noise is ...

Galaxies, 2021 Polarized synchrotron emission from the radio halos of diffuse intracluster medium (ICM) in galaxy clusters are yet to be observed. To investigate the expected polarization in the ICM, we use high resolution (1 kpc) magnetohydrodynamic simulations of ...

An Insight into the Potassium Currents of hERG and Their Simulation
Molecules, 2023 By assuming that a stepwise outward movement of the four S4 segments of the hERG potassium channel determines a concomitant progressive increase in the flow of the permeant potassium ions, the inward and outward potassium currents can be simulated by ...

Lidar Observed Optical Properties of Tropical Cirrus Clouds Over Gadanki Region
Frontiers in Earth Science, 2020 The presence of cirrus cloud has its impact on the earth’s radiation budget. In order to study the effect of cirrus clouds in the tropical regions, it is essential to understand, and characterize their optical properties.
