Information Geometry of Nonlinear Stochastic Systems [PDF]

open access: yesEntropy, 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

open access: yesTranslational 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).

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

open access: yesCommunications 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]

open access: yesKafkas 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

open access: yesIEEE 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

open access: yesJournal 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.

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

open access: yesEuropean 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.

THE WORKSHOPS ON STOCHASTIC GEOMETRY, STEREOLOGY AND IMAGE ANALYSIS

open access: yesImage Analysis and Stereology, 2017
The workshops on stochastic geometry, stereology and image analysis have been held every second year since 1981. Over the years, the workshops have increased in size and in impact too.

HOW MANY LOBSTERS ARE IN THE SEA?

open access: yesImage Analysis and Stereology, 2011
A lobster fishery must have a reasonable estimate of the number of lobsters within the fishery in order to regulate the annual harvest. Stereological sampling procedures are used to estimate the number of lobsters in a defined region of the sea.

Information Geometry on Complexity and Stochastic Interaction

open access: yesEntropy, 2015
Interdependencies of stochastically interacting units are usually quantified by the Kullback-Leibler divergence of a stationary joint probability distribution on the set of all configurations from the corresponding factorized distribution.
