Hydrodynamization in the first-order causal and stable hydrodynamics- part1


Abstract: In my first talk, I review some basic concepts such as the early thermalization puzzle, hydrodynamization paradigm, and stability/casualty problem. I also speculate on a possible way to understand hydrodynamization in conformal theories. In my second talk, I present our results on the hydrodynamization in the first-order causal and stable(FOCS) hydrodynamics, with an emphasis on the differences between the FOCS and more traditional approaches.

DM halo morphological types of MW-like galaxies in the TNG50 simulation: Simple Twisted or Stretched


One of the most intriguing properties of the dark matter (DM) halos in the Milky Way galaxy is its morphological structure. It is well motivated to approximate the DM halo shape with a triaxial ellipsoid and find the radial profile of the semi-major and semi-minor axes of that ellipsoid. Yet the correspondence between the Eigen-Values and Eigen-Vectors of this ellipsoid is left to be understood and contains novel information about the halo structure and its merger history. In this talk I will present a new way of analyzing the DM morphology and more general galactic shape that enables us to categorize different halo types. Using TNG50 run of ...

Computational membrane remodeling in soft matter and biophysics


Computational membrane remodeling in soft matter and biophysics


Membrane remodelling plays a critical role in many physical and biological/cellular processes including synthetic biology, drug delivery, cellular uptake of nano containers, and self-assembly of nanostructures at membrane interface. We have developed a triangulated coarse-grained membrane model which is capable of rapid and efficient simulation of membrane remodelling. We report tubular membrane structures induced by adsorbed nanoparticles on vesicles and investigate the role of membrane curvature and size and shape of the particles o ...

The role of noise correlations in information coding by neural populations

In sensory cortices, information about external stimuli is conveyed by collective neural activities. Small neural populations often express perceptual sensitivity of psychophysical observers, suggesting that stimulus properties are redundantly coded by correlated neurons. This implies the existence of 'information-limiting' structures in noise correlations, which limit information as the population size increases. However, the existence of such correl ...

Generalized Descriptive Set Theory under I0


At the beginning of the 20th century some �pathological� sets appeared in the theory of the reals, like the Vitali set and the Bernstein set, that were somewhat counterintuitive. Descriptive set theory was developed initially to make sense of this: it creates a hierarchy of sets of reals, from the simplest ones to the most complex, both from logical and topological points of view. It turns out that �simple� sets are well-behaved, and they agree to our intuition (for example, all Borel sets are Lebesgue measurable). The question is, then, where exactly is the border, in the hierarchy, between well-behaved and pathol ...
