Faraday Rotation and Depolarization of Galactic Radio Emission [PDF]

arXiv, 2004
A joint action of depth and bandwidth depolarization in the interstellar medium is considered using a model of N homogeneous synchrotron layers with Faraday rotation. The bandwidth depolarization can be used in multifrequency polarimetric observations of Galactic diffuse synchrotron radio emission to investigate the interstellar ionized medium and ...

Designing recommender systems to depolarize

First Monday, 2022
Polarization is implicated in the erosion of democracy and the progression to violence, which makes the polarization properties of large algorithmic content selection systems (recommender systems) a matter of concern for peace and security. While algorithm-driven social media do not seem to be a primary driver of polarization at the country level, they

The role of depolarization in the survival and differentiation of cerebellar granule cells in culture

Journal of Neuroscience, 1987
Cultures greatly enriched in granule cells from early postnatal cerebellum (P8) were grown in a medium containing fetal calf serum. Under the conditions used, nerve cells died, usually within a week, unless the K+ concentration in the medium was greater ...

How to Achieve High Spatial Resolution in Organic Optobioelectronic Devices?

Advanced Materials Interfaces, EarlyView.
This study explores how the optoelectronic properties of organic semiconductors impact on the resolution of light‐activated bioelectronic interfaces. Using photovoltage and photocurrent microscopy techniques, the authors show that H2PC/PTCDI heterojunctions enable a resolution down to 6.5 µm due to low carrier mobility along the heterojunction.

Noise effects for the Depolarizing Channel [PDF]

arXiv, 1999
The possibility of stochastic resonance of a quantum channel and hence the noise enhanced capacity of the channel is explored by considering the depolarizing channel. The fidelity of the channel is also considered. Although there is no clear evidence for noise enhanced capacity found, there is enhancement for the fidelity for the depolarizing channel ...
