Effects of temporal correlations on cascades: Threshold models on temporal networks [PDF]

open access: yesPhysical Review E, 2014
A person's decision to adopt an idea or product is often driven by the decisions of peers, mediated through a network of social ties. A common way of modeling adoption dynamics is to use threshold models, where a node may become an adopter given a high enough rate of contacts with adopted neighbors.

Temporal distribution characteristics of earthquakes in Taiwan, China

open access: yesFrontiers in Earth Science, 2023
The characteristics of seismic temporal distribution represent an important basis for earthquake prediction and seismic hazard analysis. In this paper, based on the seismic catalogs in Taiwan, and using Poisson (exponential distribution), Gamma ...

Long-range, critical-point dynamics in oil field flow rate data [PDF]

open access: yes, 2006
Earthquake triggering data exhibit long-range spatio-temporal correlations of the power-law form C(l) ∼ l−α and anomalously-slow temporal diffusion of the mean triggering distance of the form: 〈l〉 ∼ tH, with H < 0.5.

Recurrent Neural Network Based Link Quality Prediction for Fluctuating Low Power Wireless Links

open access: yesSensors, 2022
One of the main methods for link quality prediction is to predict the physical layer parameters first, and then evaluate the link quality based on the mapping models between such parameters and packet reception ratio (PRR).

The neural correlates of temporal reward discounting [PDF]

open access: yesWIREs Cognitive Science, 2013
Temporal reward discounting (TD) refers to the decrease in subjective value of a reward when the delay to that reward increases. In recent years, a growing number of studies on the neural correlates of temporal reward discounting have been conducted. This article focuses on functional magnetic resonance imaging (fMRI) studies on TD in humans. First, we
