Exploring the threshold of epidemic spreading for a stochastic SIR model with local and global contacts
(Elsevier Science, 2019-10)
The spread of an epidemic process is considered in the context of a spatial SIR stochastic model that includes a parameter 0 ≤ p ≤ 1 that assigns weights p and 1−p to global and local infective contacts respectively. The ...
Near-threshold properties of the electronic density of layered quantum dots
(American Physical Society, 2012-04)
We present a way to manipulate an electron trapped in a layered quantum dot based on near-threshold properties of one-body potentials. First, we show that potentials with a simple global parameter allow the manipulation ...
Model-based local thresholding for canopy hemispherical photography
(National Research Council Canada-NRC Research Press, 2018-07)
Canopy hemispherical photography (HP) is widely used to estimate forest structural variables. To achieve good results with HP, a classification algorithm is needed to produce binary images to accurately estimate the gap ...
Activation thresholds in epidemic spreading with motile infectious agents on scale-free networks

Determining fuel moisture thresholds to assess wildfire hazard: A contribution to an operational early warning system
(Public Library of Science, 2018-10-04)
Fuel moisture content (FMC) is an important fuel property for assessing wildfire hazard, since it influences fuel flammability and fire behavior. The relationship between FMC and fire activity differs among land covers and ...
Forest cover, extinction thresholds and time lags in woody plants (Myrtaceae) in the Brazilian Atlantic Forest: resources for conservation
(2013)
Efforts to conserve tropical forests could be strengthened based on ecological knowledge, such as extinction thresholds in ecological processes. Many studies of extinction thresholds associated with habitat reduction have ...
Threshold temperatures and degree-day estimates for embryonic development of the invasive apple snail Pomacea canaliculata (Caenogastropoda: Ampullariidae)
(Institute of Malacology, 2012-12)
Pomacea canaliculate is a freshwater snail native to subtropical-temperate South America that has invaded several countries around the world. Temperature is probably one of the main limitations to the expansion of this and ...
