Disease Phenotypes and Mechanisms of iPSC-Derived Cardiomyocytes From Brugada Syndrome Patients With a Loss-of-Function SCN5A Mutation

Frontiers in Cell and Developmental Biology, 2020
Brugada syndrome (BrS) is one of the major causes of sudden cardiac death in young people, while the underlying mechanisms are not completely understood.

A Framework on Polarization, Cognitive Inflexibility, and Rigid Cognitive Specialization

Frontiers in Psychology, 2022
Polarization is pervasive in the current sociopolitical discourse. Polarization tends to increase cognitive inflexibility where people become less capable of updating their beliefs upon new information or switching between different ways of thinking ...

L-Band Vegetation Optical Depth Estimation Using Transmitted GNSS Signals: Application to GNSS-Reflectometry and Positioning

Remote Sensing, 2020
At L-band (1–2 GHz), and particularly in microwave radiometry (1.413 GHz), vegetation has been traditionally modeled with the τ-ω model. This model has also been used to compensate for vegetation effects in Global Navigation Satellite Systems ...

The role of action potential changes in depolarization-induced failure of excitation contraction coupling in mouse skeletal muscle

eLife, 2022
Excitation-contraction coupling (ECC) is the process by which electrical excitation of muscle is converted into force generation. Depolarization of skeletal muscle resting potential contributes to failure of ECC in diseases such as periodic paralysis ...

Modulation of Depolarization for Optical Data Links

IEEE Photonics Journal, 2022
Controlled depolarization of a polychromatic carrier can be applied simultaneously with polarization-shift keying (PolSK) to achieve a three-dimensional symbol space using only a direct-detection Stokes-vector receiver.

Guaranteeing Completely Positive Quantum Evolution [PDF]

, 2021
In open quantum systems, it is known that if the system and environment are in a product state, the evolution of the system is given by a linear completely positive (CP) Hermitian map. CP maps are a subset of general linear Hermitian maps, which also include non completely positive (NCP) maps.

PINK1 stabilized by mitochondrial depolarization recruits Parkin to damaged mitochondria and activates latent Parkin for mitophagy

Journal of Cell Biology, 2010
Defective mitochondrial quality control is shown to be a mechanism for neurodegeneration in some forms of Parkinson's disease.

Correlation between Lesion Progression and Depolarization Assessed by Polarization-Sensitive Optical Coherence Tomography

Applied Sciences, 2020
The detection of early stages of caries is still one of the major challenges in preservative dentistry. Since it is known from polarized light microscopy (PLM) that intrinsic enamel birefringence is affected by demineralization, polarization-sensitive ...

Depolarization and lidar ratios at 355, 532, and 1064 nm and microphysical properties of aged tropospheric and stratospheric Canadian wildfire smoke

Atmospheric Chemistry and Physics, 2018
. We present spectrally resolved optical and microphysical properties of western Canadian wildfire smoke observed in a tropospheric layer from 5–6.5 km height and in a stratospheric layer from 15–16 km height during a record-breaking smoke event on 22 ...
