LIV effects on the quantum stochastic motion in an acoustic FRW-geometry [PDF]

European Physical Journal C: Particles and Fields, 2022
It is well known in the literature that vacuum fluctuations can induce a random motion of particles which is sometimes called quantum Brownian motion or quantum stochastic motion.

Information Geometry of Nonlinear Stochastic Systems [PDF]

Entropy, 2018
We elucidate the effect of different deterministic nonlinear forces on geometric structure of stochastic processes by investigating the transient relaxation of initial PDFs of a stochastic variable x under forces proportional to -xn (n=3,5,7) and ...

Layer III pyramidal cells in the prefrontal cortex reveal morphological changes in subjects with depression, schizophrenia, and suicide

Translational Psychiatry, 2022
Brodmann Area 46 (BA46) has long been regarded as a hotspot of disease pathology in individuals with schizophrenia (SCH) and major depressive disorder (MDD).

Stochastic homogenization on perforated domains Ⅰ – Extension Operators

Networks and Heterogeneous Media, 2023
In this first part of a series of 3 papers, we set up a framework to study the existence of uniformly bounded extension and trace operators for $ W^{1, p} $-functions on randomly perforated domains, where the geometry is assumed to be stationary ergodic.

Cellular 3D-reconstruction and analysis in the human cerebral cortex using automatic serial sections

Communications Biology, 2021
Nick Larsen et al. developed a pipeline to collect and image serial sections from fixed human cortex, then apply deep learning to detect pyramidal cells from 3D reconstructions of these sections.

Unbiased estimate of the epithelial cell number and epithelial cell nuclear volume in the bulbourethral (cowper) glands of holstein bulls - a stereological study [PDF]

Kafkas Universitesi Veteriner Fakültesi Dergisi, 2013
The bulbourethral gland (or Cowper"s gland) plays an important role for fertility. It is, therefore, essential to have quantitative data about the morphological and histomorphological structure of this gland in nonpathological conditions.

A Stochastic Geometry Approach to EMF Exposure Modeling

IEEE Access, 2021
Downlink exposure to electromagnetic fields due to cellular base stations in urban environments is studied using the stochastic geometry framework. A two-dimensional Poisson Point Process is assumed for the base station distribution.

Hidden Geometry of Bidirectional Grid-Constrained Stochastic Processes

Journal of Probability and Statistics, 2021
Bidirectional Grid Constrained (BGC) stochastic processes (BGCSPs) are constrained Itô diffusions with the property that the further they drift away from the origin, the more the resistance to movement in that direction they undergo.
