Geometry of depolarizing channels [PDF]
Physical Review A, 2008 Depolarizing maps acting on an N dimensional system are completely positive maps resulting into compression of the Bloch ball along the different polarization directions. In the qubit case these maps are a convex sum of four extremal maps and form a simplex in the space of compression coefficients along the three polarization directions.

Correcting Bandwidth Depolarization by Extreme Faraday Rotation [PDF]
, 2023 Measurements of the polarization of radio emission are subject to a number of depolarization effects such as bandwidth depolarization, which is caused by the averaging effect of a finite channel bandwidth combined with the frequency-dependent polarization caused by Faraday rotation.

Brainstem spreading depolarization and cortical dynamics during fatal seizures in Cacna1a S218L mice
Brain : a journal of neurology, 2019 Sudden unexpected death in epilepsy (SUDEP) is a fatal complication of epilepsy in which brainstem spreading depolarization may play a pivotal role, as suggested by animal studies.

Canals beyond Mars: Beam depolarization in radio continuum maps of the warm ISM [PDF]
Astron.Astrophys. 421 (2004) 1011-1019, 2004 Multi-frequency radio polarimetric observations of the diffuse Galactic synchrotron background enable us to study the structure of the diffuse ionized gas via rotation measure maps. However, depolarization will introduce artifacts in the resulting rotation measure, most notably in the form of narrow, elongated ``depolarization canals''.

Analysis of Antimicrobial-Triggered Membrane Depolarization Using Voltage Sensitive Dyes
Front. Cell Dev. Biol., 2016 The bacterial cytoplasmic membrane is a major inhibitory target for antimicrobial compounds. Commonly, although not exclusively, these compounds unfold their antimicrobial activity by disrupting the essential barrier function of the cell membrane.

Polyamidoamine dendrimer impairs mitochondrial oxidation in brain tissue [PDF]
, 2013 Background: The potential nanocarrier polyamidoamine (PAMAM) generation 5 (G5-NH2) dendrimer has been shown to evoke lasting neuronal depolarization and cell death in a concentration-dependent manner. In this study we explored the early progression of G5-

Landscape of the PARKIN-dependent ubiquitylome in response to mitochondrial depolarization
Nature, 2013 The PARKIN ubiquitin ligase (also known as PARK2) and its regulatory kinase PINK1 (also known as PARK6), often mutated in familial early-onset Parkinson’s disease, have central roles in mitochondrial homeostasis and mitophagy. Whereas PARKIN is recruited
