Journal ArticleDOI
Self-organization and a dynamical transition in traffic-flow models.
TL;DR: A simple model that describes traffic flow in two dimensions finds a sharp jamming transition that separates between the low-density dynamical phase in which all cars move at maximal speed and the high-density jammedphase in which they are all stopped.
Journal ArticleDOI
Is the Geometry of Nature Fractal
TL;DR: In this paper, the authors surveyed the physics literature for objects that were declared to be fractal and found that most of these declarations were made on the basis of very limited ranges of data.
Journal ArticleDOI
Molecular Hydrogen Formation on Astrophysically Relevant Surfaces
TL;DR: In this paper, the authors analyzed the formation of molecular hydrogen on astrophysically relevant surfaces under conditions close to those encountered in the interstellar medium using rate equations and fitted the parameters of the rate equation model to temperature-programmed desorption curves obtained in the laboratory.
Journal ArticleDOI
Regulation of phenotypic variability by a threshold-based mechanism underlies bacterial persistence
Eitan Rotem,Adiel Loinger,Irine Ronin,Irit Levin-Reisman,Chana Gabay,Noam Shoresh,Ofer Biham,Nathalie Q. Balaban +7 more
TL;DR: It is concluded that toxin–antitoxin modules in general represent a mixed network motif that can serve to produce a subpopulation of dormant cells and to supply a mechanism for regulating the frequency and duration of growth arrest.
Journal ArticleDOI
Regulation of gene expression by small non-coding RNAs: a quantitative view.
Yishai Shimoni,Gilgi Friedlander,Guy Hetzroni,Gali Niv,Shoshy Altuvia,Ofer Biham,Hanah Margalit +6 more
TL;DR: It is shown quantitatively that regulation by sRNAs is advantageous when fast responses to external signals are needed, consistent with experimental data about its involvement in stress responses, and thatregulation by sRNA may provide fine‐tuning of gene expression.
