Gaussian process emulators for the undrained bearing capacity of spatially random soils using cell-based smoothed finite element method

Journal of Rock Mechanics and Geotechnical Engineering
In this paper, we propose a novel probabilistic method for predicting the undrained bearing capacity of spatially variable soils. Our approach combines a Gaussian process regression (GPR)-based surrogate model with random cell-based smoothed finite ...

Cooperation among Virtual Anthropoids in a Complex Environment [PDF]

Interdisciplinary Description of Complex Systems, 2011
This paper presents an agent based model of the evolution of cooperation in a complex environment. Anthropoid agents reproduce sexually, and live in a world where food is irregularly distributed in space and seasonally produced. They can share food, form

Linking Memories across Time via Neuronal and Dendritic Overlaps in Model Neurons with Active Dendrites

Cell Reports, 2016
Memories are believed to be stored in distributed neuronal assemblies through activity-induced changes in synaptic and intrinsic properties. However, the specific mechanisms by which different memories become associated or linked remain a mystery.

Neural networks and physical systems with emergent collective computational abilities.

Proceedings of the National Academy of Sciences of the United States of America, 1982
Computational properties of use of biological organisms or to the construction of computers can emerge as collective properties of systems having a large number of simple equivalent components (or neurons).

Intrinsic Cellular Properties and Connectivity Density Determine Variable Clustering Patterns in Randomly Connected Inhibitory Neural Networks

Frontiers in Neural Circuits, 2016
The plethora of inhibitory interneurons in the hippocampus and cortex play a pivotal role in generating rhythmic activity by clustering and synchronizing cell firing.

The mechanisms of potassium loss in acute myocardial ischemia: New insights from computational simulations

Frontiers in Physiology, 2023
Acute myocardial ischemia induces hyperkalemia (accumulation of extracellular potassium), a major perpetrator of lethal reentrant ventricular arrhythmias.

A COMPUTATIONAL MODEL OF MOTOR NEURON DEGENERATION

Neuron, 2014
SUMMARY To explore the link between bioenergetics and motor neuron degeneration, we used a computational model in which detailed morphology and ion conductance are paired with intracellular ATP production and consumption.

A Computational Model of Working Memory Based on Spike-Timing-Dependent Plasticity

Frontiers in Computational Neuroscience, 2021
Working memory is closely involved in various cognitive activities, but its neural mechanism is still under exploration. The mainstream view has long been that persistent activity is the neural basis of working memory, but recent experiments have ...

Tinnitus with a Normal Audiogram: Physiological Evidence for Hidden Hearing Loss and Computational Model

Journal of Neuroscience, 2011
Ever since Pliny the Elder coined the term tinnitus, the perception of sound in the absence of an external sound source has remained enigmatic. Traditional theories assume that tinnitus is triggered by cochlear damage, but many tinnitus patients present ...
