Stochastic Modeling of Calcium in 3D Geometry [PDF]

open access: yesBiophysical Journal, 2009
Release of inflammatory mediators by mast cells in type 1 immediate-hypersensitivity allergic reactions relies on antigen-dependent increases in cytosolic calcium. Here, we used a series of electron microscopy images to build a 3D reconstruction representing a slice through a rat tumor mast cell, which then served as a basis for stochastic modeling of ...

Stochastic Geometry Analysis of Large Intelligent Surface-Assisted Millimeter Wave Networks

open access: yesIEEE Journal on Selected Areas in Communications, 2020
Reliable and efficient networks are the trend for next-generation wireless communications. Recent improved hardware technologies – known as Large Intelligent Surfaces (LISs) – have decreased the energy consumption of wireless networks, while ...

The eternal fractal in the universe [PDF]

open access: yes, 2001
Models of eternal inflation predict a stochastic self-similar geometry of the universe at very large scales and allow existence of points that never thermalize.

An Evaluation of Non-Stochastic Lattice Structures Fabricated Via Electron Beam Melting [PDF]

open access: yes, 2006
Metal foam structures have many applications and can be used as structural supports, heat exchangers, shock absorbers, and implant materials. Stochastic metal foams having different cell sizes and densities have been commercially available for a number

A tractable closed form approximation of the ergodic rate in Poisson cellular networks

open access: yesEURASIP Journal on Wireless Communications and Networking, 2019
The employment of stochastic geometry for the analysis and design of ultra dense networks (UDNs) has provided significant insights into network densification.

Discrete space-time geometry and skeleton conception of particle dynamics

open access: yes, 2011
It is shown that properties of a discrete space-time geometry distinguish from properties of the Riemannian space-time geometry. The discrete geometry is a physical geometry, which is described completely by the world function.

KV. Cohomology and some applications [PDF]

open access: yes, 2020
Two versions of the KV-cohomology are presented and some algebraic and geometrical applications are given. We will see some applications to stochastic manifold. As a consequence, we can apply these ideas in Lorentzian geometry, in particular in

An Exploration Algorithm for Stochastic Simulators Driven by Energy Gradients

open access: yesEntropy, 2017
In recent work, we have illustrated the construction of an exploration geometry on free energy surfaces: the adaptive computer-assisted discovery of an approximate low-dimensional manifold on which the effective dynamics of the system evolves ...

Discrete stochastic approximations of the Mumford-Shah functional [PDF]

open access: yes, 2019
We propose a $\Gamma$-convergent discrete approximation of the Mumford-Shah functional. The discrete functionals act on functions defined on stationary stochastic lattices and take into account general finite differences through a non-convex potential ...
