A Maximum Spreading Speed for Magnetopause Reconnection [PDF]
Geophysical Research Letters, 2018 AbstractPast observations and numerical modeling find magnetic reconnection to initiate at a localized region and then spread along a current sheet. The rate of spreading has been proposed to be controlled by a number of mechanisms based on the properties within the boundary.

Community lockdowns in social networks hardly mitigate epidemic spreading
New Journal of Physics, 2021 Community lockdowns and travel restrictions are commonly employed to decelerate epidemic spreading. We here use a stochastic susceptible-infectious-recovered model on different social networks to determine when and to what degree such lockdowns are ...

Spreading speeds and traveling wavefronts for second order integrodifference equations [PDF]
, 2010 This paper is concerned with the spreading speeds and traveling wavefronts for second order integrodifference equations. By introducing an auxiliary integrodifference system, the spreading speed is established for the integrodifference equation.

Minimal Wave Speed in an Integrodifference System of Predator-Prey Type
Discrete Dynamics in Nature and Society, 2020 This article studies the minimal wave speed of traveling wave solutions in an integrodifference predator-prey system that does not have the comparison principle. By constructing generalized upper and lower solutions and utilizing the theory of asymptotic

Spreading speeds and traveling waves in some population models. [PDF]
, 2015 Virtually every ecosystem has been invaded by exotic organisms with potentially drastic consequences for the native fauna or flora. Studying the forms and rates of invading species has been an important topic in spatial ecology.

Fleet size estimation for spreading operation considering road geometry, weather and traffic
Journal of Traffic and Transportation Engineering (English ed. Online), 2014 Extreme weather conditions(i.e. snow storm) in winter time have caused significant travel disruptions and increased delay and traffic accidents. Snow plowing and salt spreading are the most common counter-measures for making our roads safer for motorists.

Fronts with a growth cutoff but with speed higher than the linear spreading speed
Physical Review E, 2002 Fronts, propagating into an unstable state phi=0, whose asymptotic speed v(as) is equal to the linear spreading speed v* of infinitesimal perturbations about that state (so-called pulled fronts), are very sensitive to changes in the growth rate f(phi) for phi0.

Modelling the biological invasion of Carcinus maenas (the European green crab)
Journal of Biological Dynamics, 2016 This paper proposes a system of integro-difference equations to model the spread of Carcinus maenas, commonly called the European green crab, that causes severe damage to coastal ecosystems. A model with juvenile and adult classes is first studied. Here,
