Singularities in Speckled Speckle
Isaac Freund, David A. Kessler
Speckle patterns produced by random optical fields with two (or more) widely different correlation lengths exhibit speckle spots that are themselves highly speckled. Using computer…
Short and Long Range Screening of Optical Singularities
David A. Kessler, Isaac Freund
Screening of topological charges (singularities) is discussed for paraxial optical fields with short and with long range correlations. For short range screening the charge variance…
Epidemic Size in the Sis Model of Endemic Infec- Tions
David A. Kessler
We study the Susceptible-Infected-Susceptible model of the spread of an endemic infection. We calculate an exact expression for the mean number of transmissions for all values of t…
Transition Phenomena Induced by Internal Noise and Quasi-absorbing State
Jun Ohkubo, Nadav Shnerb, David A. Kessler
We study a simple chemical reaction system and effects of the internal noise. The chemical reaction system causes the same transition phenomenon discussed by Togashi and Kaneko [Ph…
Solution of an infection model near threshold
David A. Kessler, Nadav M. Shnerb
We study the Susceptible-Infected-Recovered model of epidemics in the vicinity of the threshold infectivity. We derive the distribution of total outbreak size in the limit of large…
