A small-correlation expansion to quantify information in noisy sensory systems
Gabriel Mahuas, Olivier Marre, Thierry Mora +1
Neural networks encode information through their collective spiking activity in response to external stimuli. This population response is noisy and strongly correlated, with comple…
Population spiking and bursting in next generation neural masses with spike-frequency adaptation
Alberto Ferrara, David Angulo-Garcia, Alessandro Torcini +1
Spike-frequency adaptation (SFA) is a fundamental neuronal mechanism taking into account the fatigue due to spike emissions and the consequent reduction of the firing activity. We…
3D Spectroscopic Tracking of Individual Brownian Nanoparticles during Galvanic Exchange
Minh-Chau Nguyen, Pascal Berto, Fabrice Valentino +4
Monitoring chemical reactions in solutions at the scale of individual entities is challenging: single particle detection requires small confocal volumes which are hardly compatible…
Hollow-core fibers with reduced surface roughness and ultralow loss in the short-wavelength range
Jonas H. Osório, Foued Amrani, Frédéric Delahaye +9
While optical fibers display excellent performances in the infrared, visible and ultraviolet ranges remain poorly addressed by them. Obtaining better fibers for the short-wavelengt…
Diagrammatics for the Inverse Problem in Spin Systems and Simple Liquids
Tobias Kühn, Frédéric van Wijland
Modeling complex systems, like neural networks, simple liquids or flocks of birds, often works in reverse to textbook approaches: given data for which averages and correlations are…
