SUMMARY:Jonathan Ron\, "Deterministic cell motility patterns across scales and sizes"
DESCRIPTION:Cell motility plays a crucial role in various biological processes\, such as embryogenesis\, wound healing\, and immune response. Although the complex molecular machinery driving cell motility is relatively well understood\, it remains unclear how cells exhibit such diverse migration patterns\, both individually and collectively. This seminar will focus on a recently developed theoretical framework for cellular migration\, which couples migration features such as polarization\, speed\, and size to traction forces and adhesion dynamics. The discussion will begin with the model’s predictions for one-dimensional migration of single cells\, emphasizing how symmetry is broken during directional decision-making. The model will then be extended to describe cell-cell interactions and the collective behavior of one-dimensional multicellular trains. A two-dimensional stochastic version of the model will also be introduced\, explaining the run-and-tumble behavior commonly exhibited by cells. Finally\, a new theory will be introduced\, linking cell migration to volume regulation via active ion transport. The results presented in the seminar will be supported by extensive experimental validation conducted on various cell types.\n Ron\, J.E.\, Monzo\, P.\, Gauthier\, N.C.\, Voituriez\, R. and Gov\, N.S.\, 2020.

SUMMARY:Enrico Morgante: Gravitational waves from confinement in improved holographic QCD
DESCRIPTION:I will discuss gravitational waves produced during the confinement phase transition in SU(N) Yang-Mills\, using a holographic description. The key ingredient will be the construction of the effective action\, with the kinetic term playing an important role.\nhttps://indico.ijs.si/event/2680/

SUMMARY:Petr Šulc\, "DNA and RNA nanotechnology: molecular computing\, therapeutics\, and the quest for the holy grail of self-assembly"
DESCRIPTION:The control over the self-assembly of complex structures is a long-standing challenge of biomimetic nanotechnology\, as the desired assembly pathway is often kinetically derailed by the formation of competing alternative structures or amorphous aggregates. The goal of inverse design problem is hence to find a set of blocks that reliably assemble in high yield into a target structure while avoiding kinetic traps and alternative competing states. We present here a framework called SAT-assembly\, which solves this problem by combination of multiscale molecular simulation\, graph theory\, and constrained optimization methods. While the general approach is abstract\, the proposed designs can be realized experimentally e.g. with building blocks made out of DNA or RNA strands. We then show how our models are used to guide experimental realization of highly coveted nanostructure shapes with applications ranging from therapeutic delivery to nanoscale templating\, including designs such as capsids\, diamond lattices\, 3D polycube assemblies\, and dynamic reconfigurable multifarious structures\, which can switch between multiple possible stable folds.\nhttps://indico.ijs.si/event/2744/
