Information Theory in Transmembrane Transport

The past decades have seen the advent of information theory in various fields, from quantum physics to cosmology.At an intermediary scale between atomic and cosmological scales are biological systems and in particular the cell, as a constitutive element of ...

Gyrokinetic simulations of turbulence and zonal flows driven by steep profile gradients using a delta-f approach with an evolving background Maxwellian

Laurent Villard, Stephan Brunner, Alberto Bottino, Ben McMillan, Moahan Murugappan

Long global gyrokinetic turbulence simulations are particularly challenging in situations where the system deviates strongly from its initial state and when fluctuation levels are high, for example, in strong gradient regions. For particle-in-cell simulati ...

Dissipation-driven selection of states in non-equilibrium chemical networks

Paolo De Los Rios, Daniel Maria Busiello, Shiling Liang, Francesco Piazza

Life has most likely originated as a consequence of processes taking place in non-equilibrium conditions (e.g. in the proximity of deep-sea thermal vents) selecting states of matter that would have been otherwise unfavorable at equilibrium. Here we present ...

Negentropic linguistic evolution: A comparison of seven languages

Frédéric Kaplan, Vincent Christian Buntinx

The relationship between the entropy of language and its complexity has been the subject of much speculation – some seeing the increase of linguistic entropy as a sign of linguistic complexification or interpreting entropy drop as a marker of greater regul ...

Approximate Cloaking via Transformation Optics for Electromagnetic Waves

Xuan Loc Tran

Cloaking via transformation optics was introduced by Pendry, Schurig, and Smith for the Maxwell system and Leonhardt in the geometric optics setting. They used a singular change of variables which blows up a point into a cloaked region. The same transforma ...

Optimal Search Strategies for Pollutant Source Localization

Auke Ijspeert, Howard Li

This paper is aimed at developing optimal motion planning for a single autonomous surface vehicle (ASV) equipped with an on-board pollutant sensor that will maximize the sensor-related information available for source seeking. The ASV uses a nonlinear diff ...

Theory of the jamming transition at finite temperature

Matthieu Wyart, Eric DeGiuli

A theory for the microscopic structure and the vibrational properties of soft sphere glass at finite temperature is presented. With an effective potential, derived here, the phase diagram and vibrational properties are worked out around the Maxwell critica ...

Asymmetric Particle Behavior during Size Segregation

Christophe Ancey, Kasper van der Vaart

We have performed oscillatory shear experiments on a bidisperse granular mixture in combination with refractive index matched scanning in order to resolve particle motion in three-dimensions during size-segregation. We find that small particles segregate f ...

The quest for the most spherical bubble: experimental setup and data overview

Mohamed Farhat, Nicolas Dorsaz, Danail Obreschkow, Philipp Kobel, Aurèle De Bosset, Marc Tinguely

We describe a recently realized experiment producing the most spherical cavitation bubbles today. The bubbles grow inside a liquid from a point plasma generated by a nanosecond laser pulse. Unlike in previous studies, the laser is focussed by a parabolic m ...

Hydrodynamics and the Fluctuation Theorem

Giuseppe Foffi, Maxim Belushkin

The fluctuation theorem is a pivotal result of statistical physics. It quantifies the probability of observing fluctuations which are in violation of the second law of thermodynamics. More specifically, it quantifies the ratio of the probabilities of obser ...
