| 09:00 - 17:30 One day Workshop on Experimental Particle Physics: Detector & Applied Electronics School PARTICLES AND ACCELERATORS The goal of the workshop is to introduce detectors, and the future developing of electronic readout with its application in particle physics. We will also review the IPM engagement in designing electronic upgrades for the Muon detector (RPC) of the CMS experiment at the LHC high luminosity operation. Larak Seminar Room ... 11:00 - 13:00 Theoretical Neuroscience Journal Club A triplet spike-timing-dependent plasticity model generalizes the Bienenstock-Cooper-Munro rule to higher-order spatiotemporal correlations School COGNITIVE SCIENCES Venue: School of Cognitive Sciences, Institute for Research in Fundamental Sciences (IPM), Opposite the ARAJ, Artesh Highway, Tehran, Iran ... 11:00 - 12:00 Computational Nanoscience journal club Using Time-Temperature Superposition for Determining Dielectric Loss in Functionalized Polyethylenes School NANO SCIENCES Using Time-Temperature Superposition for Determining Dielectric Loss in Functionalized Polyethylenes Abstract: Using Molecular Dynamics simulations, we probe the effect of various pendant polar groups on the dielectric loss of polyethylene copolymers. The dielectric loss was computed using the autocorrelation function of the total dipole moment of a completely relaxed PE-X sample. Since this calculation is computationally expensive (wall time ? 4200 h), we explore the use of the time-temperature superposition (tTS) principle to make it more tractable. An important point is that short time MD simulations do ... 13:30 - 15:00 Weekly Seminar Vacuum decay and bubble nucleation inf(R) gravity School ASTRONOMY In this talk, I first review the concept of vacuum decay in quantum mechanics and field theory. Then I will review our study of vacuum decay and bubble nucleation in models of f(R) higher curvature gravity building upon the analysis of Coleman De Luccia (CDL). We could show that higher curvature terms may have nontrivial effects on the tunneling rate and bubble size. Our main focus is on the Starobinsky model and its higher power extensions though the formalism is rather general. Based on arXiv:1810.01391 ... 14:00 - 15:00 Lecture Tangles -vs- Trees School MATHEMATICS The topic of these talks is the structural theory of sparse graphs. More specifically, we study the interplay between highly cohesive substructures, which we figuratively refer to as `tangles', and decompositions over a (graph-theoretic) tree, which we simply call `trees'. At this point, we intentionally leave the meaning of these terms undefined and rely solely on the connotations they may carry. We are primarily interested in situations in which a certain pair of a tangle and a tree cannot coexist: the existence of the specified substructure makes a decomposition of the desired kind impossible and vice versa. For example, tree-dec ... 16:00 - 18:00 Neuroimaging Journal Club Guidelines for reporting an fMRI study School COGNITIVE SCIENCES Venue: School of Cognitive Sciences, Institute for Research in Fundamental Sciences (IPM), Opposite the ARAJ, Artesh Highway, Tehran, Iran ... |
