Biases and Variability from Costly Bayesian Inference
Arthur Prat-Carrabin, Florent Meyniel, Misha Tsodyks +1
When humans infer underlying probabilities from stochastic observations, they exhibit biases and variability that cannot be explained on the basis of sound, Bayesian manipulations…
High-Fidelity Coding with Correlated Neurons
Rava Azeredo da Silveira, Michael J. Berry
Positive correlations in the activity of neurons are widely observed in the brain. Previous studies have shown these correlations to be detrimental to the fidelity of population co…
Steady-State Chemotactic Response in E. coli
Yariv Kafri, Rava Azeredo da Silveira
The bacterium E. coli maneuvers itself to regions with high chemoattractant concentrations by performing two stereotypical moves: `runs', in which it moves in near straight lines,…
Critical Hysteresis from Random Anisotropy
Rava A. da Silveira, Stefano Zapperi
Critical hysteresis in ferromagnets is investigated through a -component spin model with random anisotropies, more prevalent experimentally than the random fields used in most t…
Temperature and Disorder Chaos in Low Dimensional Directed Paths
Rava A. da Silveira, Jean-Philippe Bouchaud
The responses of a dimensional directed path to temperature and to potential variations are calculated exactly, and are governed by the same scaling form. The short scale dec…
Ultrasharp Crossover from Quantum to Classical Decay in a Quantum Dot Flanked by a Double-Barrier Tunneling Structure
Denis A. Gorokhov, Rava A. da Silveira
The decay of metastable states is dominated by quantum tunneling at low temperatures and by thermal activation at high temperatures. The escape rate of a particle out of a square w…
