Dear All,

today, Tuesday 26 January 2021 at 15:00 CET, Daniel Sears, Yale 
University, will give a webinar titled:

The energetic cost of biological waves


*Abstract*: Living matter consumes energy at the microscopic scale to 
drive emergent, large-scale behaviors such as traveling waves or 
coherent oscillations. These complex, spatiotemporal phenomena play 
pivotal roles in essential life processes, such as cell division, cell 
polarization, and collective migration. While much work has focused on 
understanding the dynamics of these behaviors, we lack a thorough 
understanding of their energetic underpinnings. To address this, we 
introduce a measure of irreversibility we term the entropy production 
factor that estimates energy dissipation across time and space for 
spatially extended systems. We use our method to study the emergence of 
synchronized oscillations in a model biochemical oscillator, finding 
signatures of the onset of oscillations in the total irreversibility, 
while signatures of synchronization are found in the distribution of 
irreversibility across spatiotemporal frequencies. This work provides a 
tool for understanding the connection between microscopic energy 
consumption and macroscopic dynamic phenomena in non-equilibrium systems.
