Talk on Thursday Feb 03, 2022 at 11:00 Place: Zoom Seminar Title: Liquid-Hexatic-Solid phases in active and passive Brownian particles driven by stochastic birth-death events Speaker: Alejandro Almodóvar Del Pozo, IFISC Abstract: The behaviour of active matter has been intensively investigated in the last decades partly because of its many applications to living systems. In this work we add stochastic birth-death dynamics to a system of particles with volume exclusion. This is a simple, but general biological ingredient and has not been studied in detail before. The number of particles in the system at long times depends on the birth and death rates, and on a parameter characterising the activity of self-propelled particles. We find liquid, solid and hexatic phases in the absence of activity. Which one of these phases is realised depends on the birth and death rates. In active systems we also find motility induced phase separation (MIPS) when the self-propulsion velocity is large and the birth rate small enough. In the MIPS phase the solid and liquid states coexist. <a href="https://us02web.zoom.us/j/83829318876?pwd=Z2pqbUtIMEV3NUQvU0hpakp0NGtsUT09">https://us02web.zoom.us/j/83829318876?pwd=Z2pqbUtIMEV3NUQvU0hpakp0NGtsUT09</a> Url event:https://ifisc.uib-csic.es/en/events/seminars/liquid-hexatic-solid-phases-in-active-and-passive/

IFISC Seminar on Wednesday Jan 26, 2022 at 14:30 Place: Zoom Seminar Title: Discrete and continuum methods to investigate pattern formation in growing cell populations Speaker: Fiona Macfarlane, University of St. Andrews Abstract: Stochastic individual-based modelling approaches allow for the investigation of complex biological systems, for example cell populations that exhibit single cell dynamics. These models generally include rules that each cell follows independently of other cells in the population. We have developed a range of IB models that describe biological systems in the context of pattern formation. From these models we have derived the continuum limits from the underlying random walk, providing a deterministic PDE description of these processes. Ultimately, the results illustrate how the simple rules governing the dynamics of single cells in an individual-based model can lead to the emergence of complex spatial patterns of population growth. &nbsp; <a href="https://us02web.zoom.us/j/83829318876?pwd=Z2pqbUtIMEV3NUQvU0hpakp0NGtsUT09">https://us02web.zoom.us/j/83829318876?pwd=Z2pqbUtIMEV3NUQvU0hpakp0NGtsUT09</a> Url event:https://ifisc.uib-csic.es/en/events/seminars/discrete-and-continuum-methods-to-investigate-patt/

IFISC Seminar on Wednesday Jan 19, 2022 at 14:30 Place: Zoom Seminar Title: Quantitative comparisons between models and data to provide new insights in cell and developmental biology Speaker: Ruth Baker, University of Oxford Abstract: &nbsp; Simple mathematical models have had remarkable successes in biology, framing how we understand a host of mechanisms and processes. However, with the advent of a host of new experimental technologies, the last ten years has seen an explosion in the amount and types of quantitative data now being generated. This sets a new challenge for the field &ndash; to develop, calibrate and analyse new models to interpret these data. In this talk I will use examples relating to intracellular transport and cell motility to showcase how quantitative comparisons between models and data can help tease apart subtle details of biological mechanisms.
