Disease extinction in the presence of non-Gaussian noise
Mark Dykman, Ira B. Schwartz, Alexandra S. Landsman
We investigate stochastic extinction in an epidemic model and the impact of random vaccinations in large populations. We show that, in the absence of vaccinations, the effective en…
Stochastic extinction of epidemics in large populations and role of vaccinations
Alexandra S. Landsman, Ira B. Schwartz
We investigate stochastic extinction in an epidemic model and the impact of random vaccinations in large populations formulated in terms of an optimal escape path. We find that dif…
Zero Lag Synchronization of Mutually Coupled Lasers in the Presence of Delays
Alexandra S. Landsman, Leah B. Shaw, Ira B. Schwartz
We consider a line of three mutually coupled lasers with time delays and study chaotic synchronization of the outer lasers. Two different systems are presented: optoelectronically…
Complete chaotic synchronization in mutually coupled time-delay systems
Alexandra S. Landsman, Ira B. Schwartz
Complete chaotic synchronization of end lasers has been observed in a line of mutually coupled, time-delayed system of three lasers, with no direct communication between the end la…
Predictions of ultra-harmonic oscillations in coupled arrays of limit cycle oscillators
Alexandra S. Landsman, Ira B. Schwartz
Coupled distinct arrays of nonlinear oscillators have been shown to have a regime of high frequency, or ultra-harmonic, oscillations that are at multiples of the natural frequency…
