The Geometry of Information Coding in Correlated Neural Populations
Rava Azeredo da Silveira, Fred Rieke
Neurons in the brain represent information in their collective activity. The fidelity of this neural population code depends on whether and how variability in the response of one n…
Interpretation of Correlated Neural Variability from Models of Feed-Forward and Recurrent Circuits
Volker Pernice, Rava Azeredo da Silveira
The correlated variability in the responses of a neural population to the repeated presentation of a sensory stimulus is a universally observed phenomenon. Such correlations have b…
Chemotaxis When Bacteria Remember: Drift versus Diffusion
Sakuntala Chatterjee, Rava Azeredo da Silveira, Yariv Kafri
{\sl Escherichia coli} ({\sl E. coli}) bacteria govern their trajectories by switching between running and tumbling modes as a function of the nutrient concentration they experienc…
Formation and Stability of Synaptic Receptor Domains
Christoph A. Haselwandter, Martino Calamai, Mehran Kardar +2
Neurotransmitter receptor molecules, concentrated in postsynaptic domains along with scaffold and a number of other molecules, are key regulators of signal transmission across syna…
Non-Linear Stochastic Equations with Calculable Steady States
Rava A. da Silveira, Mehran Kardar
We consider generalizations of the Kardar--Parisi--Zhang equation that accomodate spatial anisotropies and the coupled evolution of several fields, and focus on their symmetries an…
The Random Fuse Network as a Dipolar Magnet
Marc Barthelemy, Rava da Silveira, Henri Orland
We introduce an approximate mapping between the random fuse network (RFN) and a random field dipolar Ising model (RFDIM). The state of the network damage is associated with a metas…
Rippling Instability of a Collapsing Bubble
Rava da Silveira, Sahraoui Chaieb, L. Mahadevan
When a bubble of air rises to the top of a highly viscous liquid, it forms a dome-shaped protuberance on the free surface. Unlike a soap bubble, it bursts so slowly as to collapse…
An Introduction to Breakdown Phenomena in Disordered Systems
Rava da Silveira
The rupture of a medium under stress typifies breakdown phenomena. More generally, the latter encompass the dynamics of systems of many interacting elements governed by the interpl…
Critical Hysteresis for n-Component Magnets
Rava da Silveira, Mehran Kardar
Earlier work on dynamical critical phenomena in the context of magnetic hysteresis for uniaxial (scalar) spins, is extended to the case of a multicomponent (vector) field. From sym…
Comment on "Tricritical Behavior in Rupture Induced by Disorder"
Rava da Silveira
In their letter, Andersen, Sornette, and Leung [Phys. Rev. Lett. 78, 2140 (1997)] describe possible behaviors for rupture in disordered media, based on the mean field-like democrat…
