Generation of Granule Cell Dendritic Morphologies by Estimating the Spatial Heterogeneity of Dendritic Branching

open access: yesFrontiers in Computational Neuroscience, 2020
Biological realism of dendritic morphologies is important for simulating electrical stimulation of brain tissue. By adding point process modeling and conditional sampling to existing generation strategies, we provide a novel means of reproducing the ...

Markov chain Monte Carlo methods for state-space models with point process observations [PDF]

open access: yes, 2012
This letter considers how a number of modern Markov chain Monte Carlo (MCMC) methods can be applied for parameter estimation and inference in state-space models with point process observations.

Point Process Flows

open access: yesCoRR, 2019
Event sequences can be modeled by temporal point processes (TPPs) to capture their asynchronous and probabilistic nature. We propose an intensity-free framework that directly models the point process distribution by utilizing normalizing flows. This approach is capable of capturing highly complex temporal distributions and does not rely on restrictive ...

A Statistical Model for Earthquake And/Or Rainfall Triggered Landslides

open access: yesFrontiers in Earth Science, 2021
Natural hazards can be initiated by different types of triggering events. For landslides, the triggering events are predominantly earthquakes and rainfall.

Stream-Processing Points [PDF]

open access: yesIEEE Visualization 2005 - (VIS'05), 2006
With the growing size of captured 3D models it has become increasingly important to provide basic efficient processing methods for large unorganized raw surface-sample point data sets. In this paper we introduce a novel stream-based (and out-of-core) point processing framework.

On the Superposition of Point Processes

open access: yesJournal of the Royal Statistical Society Series B: Statistical Methodology, 1968
Summary Given point processes N1, …, Nm their superposition is the point process N defined by N(t) = N1(t) + … + Nm(t), t ≥ 0. An equivalent description of the system (N1, …, Nm) is by the process (Xn, Tn) where the Tn are the points of N, and Xn = k if and only if Tn is a point of Nk.

Effect of Mixing on Microorganism Growth in Loop Bioreactors

open access: yesInternational Journal of Chemical Engineering, 2012
The impact of mixing on the promotion of microorganism growth rate has been analyzed using a multiphase forced-circulation pipe-loop reactor model capable of identifying conditions under which it is possible to convert natural gas into Single-Cell ...
