Non-Hermitian delocalization and the extinction transition
David A. Kessler, Nadav M. Shnerb
Logistic growth on a static heterogenous substrate is studied both above and below the drift-induced delocalization transition. Using stochastic, agent-based simulations the deloca…
Extinction transition on diffusive substrate: a different universality class?
Galit Evron, David A. Kessler, Nadav M. Shnerb
The extinction transition on a one dimensional heterogeneous substrate with diffusive correlations is studied. Diffusively correlated heterogeneity is shown to affect the location…
Singularities in Speckled Speckle: Screening
David A. Kessler, Isaac Freund
We study screening of optical singularities in random optical fields with two widely different length scales. We call the speckle patterns generated by such fields speckled speckle…
Singularities in Speckled Speckle: Statistics
Isaac Freund, David A. Kessler
Random optical fields with two widely different correlation lengths generate far field speckle spots that are themselves highly speckled. We call such patterns speckled speckle, an…
Novel exponents control the quasi-deterministic limit of the extinction transition
David A. Kessler, Nadav M. Shnerb
The quasi-deterministic limit of the generic extinction transition is considered within the framework of standard epidemiological models. The susceptible-infected-susceptible (SIS)…
The fixation probability of rare mutators in finite asexual populations
C. Scott Wylie, Cheol-Min Ghim, David A. Kessler +1
A mutator is an allele that increases the mutation rate throughout the genome by disrupting some aspect of DNA replication or repair. Mutators that increase the mutation rate by th…
