Postsynaptic Ca2+, but not cumulative depolarization, is necessary for the induction of associative plasticity in Hermissenda [PDF]

open access: yes, 1993
The neuronal modifications that underlie associative memory in Hermissenda have their origins in a synaptic interaction between the visual and vestibular systems, and can be mimicked by contiguous in vitro stimulation of these converging pathways. At the

Acetylcholine Depolarizes Barnacle Photoreceptors [PDF]

open access: yesJournal of Experimental Biology, 1985
ABSTRACT A variety of vertebrate and invertebrate sensory cells are known to be sensitive to acetylcholine (ACh), although the purpose of ACh receptors on these cells is not understood. Acetylcholine elicits action potentials from the sensory cell of the crayfish stretch receptor organ, which receives inhibitory but not excitatory ...

SU(2)-invariant depolarization of quantum states of light [PDF]

open access: yes, 2013
We develop an SU(2)-invariant approach to the depolarization of quantum systems as the effect of random unitary SU(2) transformations. From it we derive an SU(2)-invariant Markovian master equation.

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

open access: yesFrontiers 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.

Depolarization Measurement through a Single-Mode Fiber-Based Endoscope for Full Mueller Endoscopic Polarimetric Imaging

open access: yesPhotonics, 2023
Coupled to endoscopic techniques, Mueller polarimetry has been proven to be promising for early detection of certain diseases which affect biological tissues of inner organs.

Gravitational depolarization of ultracold neutrons: comparison with data [PDF]

open access: yes, 2015
We compare the expected effects of so-called gravitationally enhanced depolarization of ultracold neutrons to measurements carried out in a spin-precession chamber exposed to a variety of vertical magnetic-field gradients.

Lidar Observed Optical Properties of Tropical Cirrus Clouds Over Gadanki Region

open access: yesFrontiers 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.

Relaxation of Spin Polarized $^3$He in Mixtures of $^3$He and $^4$He Below the $^4$He Lambda Point [PDF]

open access: yes, 2008
We report the first study of the depolarization behavior of spin polarized 3He in a mixture of 3He-4He at a temperature below the 4He Lambda point in a deuterated TetraPhenyl Butadiene-doped deuterated PolyStyrene (dTPB-dPS) coated acrylic cell.

An Approach to Extended Fresnel Scattering for Modeling of Depolarizing Soil-Trunk Double-Bounce Scattering

open access: yesRemote Sensing, 2016
Focusing on scattering from natural media, dihedral (double bounce) scattering is often characterized as a soil-trunk double Fresnel reflection, like for instance, in most model-based decompositions.

Modulation of Depolarization for Optical Data Links

open access: yesIEEE 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.
