Predicting the distribution of serotonergic axons: a supercomputing simulation of reflected fractional Brownian motion in a 3D-mouse brain model

open access: yesFrontiers in Computational Neuroscience, 2023
The self-organization of the brain matrix of serotonergic axons (fibers) remains an unsolved problem in neuroscience. The regional densities of this matrix have major implications for neuroplasticity, tissue regeneration, and the understanding of mental ...

A new view of axon growth and guidance grounded in the stochastic dynamics of actin networks

open access: yesOpen Biology, 2023
The mechanism of axon growth and guidance is a core, unsolved problem in neuroscience and cell biology. For nearly three decades, our view of this process has largely been based on deterministic models of motility derived from studies of neurons cultured

Temperley Lieb stochastic processes [PDF]

open access: yesJournal of Physics A: Mathematical and General, 2002
We discuss one-dimensional stochastic processes defined through the Temperley-Lieb algebra related to the Q=1 Potts model. For various boundary conditions, we formulate a conjecture relating the probability distribution which describes the stationary state, to the enumeration of a symmetry class of alternating sign matrices, objects that have received ...

Modeling Long-Range Dynamic Correlations of Words in Written Texts with Hawkes Processes

open access: yesEntropy, 2022
It has been clarified that words in written texts are classified into two groups called Type-I and Type-II words. The Type-I words are words that exhibit long-range dynamic correlations in written texts while the Type-II words do not show any type of ...

Layout graph model for semantic façade reconstruction using laser point clouds

open access: yesGeo-spatial Information Science, 2021
Building façades can feature different patterns depending on the architectural style, functionality, and size of the buildings; therefore, reconstructing these façades can be complicated.

Stochastic processes in gravitropism [PDF]

open access: yesFrontiers in Plant Science, 2014
In this short review we focus on the role of noise in gravitropism of plants - the reorientation of plants according to the direction of gravity. We briefly introduce the conventional picture of static gravisensing in cells specialized in sensing.

Phase Coherence Induced by Additive Gaussian and Non-gaussian Noise in Excitable Networks With Application to Burst Suppression-Like Brain Signals

open access: yesFrontiers in Applied Mathematics and Statistics, 2020
It is well-known that additive noise affects the stability of non-linear systems. Using a network composed of two interacting populations, detailed stochastic and non-linear analysis demonstrates that increasing the intensity of iid additive noise ...

Brownian Super-exponents [PDF]

open access: yes, 2006
We introduce a transform on the class of stochastic exponentials for d-dimensional Brownian motions. Each stochastic exponential generates another stochastic exponential under the transform.

Active Learning Strategy for Surrogate-Based Quantile Estimation of Field Function

open access: yesApplied Sciences, 2022
Uncertainty quantification is widely used in engineering domains to provide confidence measures on complex systems. It often requires to accurately estimate extreme statistics on computationally intensive black-box models.

The Revised Model State Administrative Procedure Act—Reform or Retrogression? [PDF]

open access: yes, 1963
In this contribution, we deal with the deterministic dominance of the probability moments of stochastic processes. More precisely, given a positive stochastic process, we propose to dominate its probability moment sequence by the trajectory of ...
