Quantitative Life Sciences Monthly Colloquium Series - every 2nd Wednesday (via Zoom)

[Quantitative Life Sciences]

The Quantitative Life Sciences section is glad to announce the QLS 
Monthly Colloquium Series, to be held every 2nd Wednesday as of 9 March, 
2022.

The first Colloquium to be held on 9 March, 2022 at 3:30pm IST (11:00am 
CET) will be "Stochastic thermodynamics of active fluctuations in the 
ear of the bullfrog", by Édgar Roldán, ICTP, Trieste.

Abstract:
Stochastic thermodynamics is an emerging  field that studies the 
thermodynamics of systems driven out of equilibrium in the presence of  
fluctuations.
Unprecedented joint theoretical and experimental advances have revealed 
novel universal thermodynamic laws at the mesoscale, which includes 
fundamental constraints for biological
processes. This colloquium will showcase recent progress on the 
application of stochastic thermodynamics to analyze  fluctuations of 
hair-cell bundles responsible of sound transduction in the bullfrog's 
sacculus. Through a holistic theory-experiment approach, it has been 
shown that spontaneous hair-cell bundle  fluctuations are 
nonequilibrium, i.e. active. Moreover, using time-irreversibility 
measures and thermodynamic uncertainty relations we have estimated the 
rate of entropy production of hair-bundle  fluctuations in different 
experimental, physiological conditions [1]. Furthermore, we have 
introduced and solved analytically a non-Markovian model that we have 
employed successfully in parametric inference and to predict the minimal 
energetic cost required to sustain spontaneous otoacoustic emissions in 
the ear of the bullfrog [2].
