09:00 - 17:00 The 14th Seminar on Commutative Algebra and Related TopicsSchool MATHEMATICS The 14th Seminar on Commutative Algebra and Related Topics ... 10:00 - 12:00 Short CourseModel Theory, p-adic Integration, and Applications to Algebra and Number Theory School MATHEMATICS This course is concerned with model-theoretic results for local fields and finite fields, and p-adic and motivic integration. The main results concern analytic properties of Euler products and applications to various zeta functions and Dirichlet series in algebra and number theory. ... 11:00 - 12:00 Computational Nano Science journal clubBorn-Oppenheimer Dynamics, Electronic Friction, and the Inclusion of Electron-Electron Interactions School NANO SCIENCES Born-Oppenheimer Dynamics, Electronic Friction, and the Inclusion of Electron-Electron InteractionsWe present a universal expression for the electronic friction as felt by a set of classical nuclear degrees of freedom (DOFs) coupled to a manifold of quantum electronic DOFs; no assumptions are made regarding the nature of the electronic Hamiltonian and electron-electron repulsions are allowed. Our derivation is based on a quantum-classical Liouville equation for the coupled electronic-nuclear motion, followed by an adiabatic approximation whereby electronic transitions are assumed to equilibrate faster than nuclear movement. ... 11:00 - 12:00 Special HEP SeminarFormation probabilities, Post-measurement entanglement entropy and Casimir effect School PHYSICS Seminar Room Class D, Farmanieh Building ... 14:00 - 15:30 Weekly SeminarSeparate Universe approach and soft modes in cosmological perturbation theory School ASTRONOMY Understanding most interesting things in the universe from fluctuations on CMB, large scales structures to galaxies and stars needs studying universe beyond homogeneous and isotropic limit. This study is the subject of the so-called "cosmological perturbation theory". In this talk, I will start off by a brief review of the cosmological perturbation theory. Afterwards, I will turn to separate universe approach to the evolution of long wave length limit of these perturbations. Then I will make a detour to Weinberg theorem of the adiabatic modes. Finally, I will briefly present our heuristic approach to study soft gravitational perturbations in ... 14:00 - 16:00 SeminarModern object detection for autonomous driving systems School COGNITIVE SCIENCES Venue: School of Cognitive Sciences, Institute for Research in Fundamental Sciences (IPM), Opposite the ARAJ, Artesh Highway, Tehran, Iran * To join the mailing list: Send an empty email to: scs at ipm dot ir on the subject of: #join ... 14:00 - 15:00 Weekly Seminar on Combinatorics and ComputingCombinatorial aspects of VC theory School MATHEMATICS Combinatorial aspects of VC theory ... 14:00 - 15:00 Weekly Seminar on Operator Algebra and its Applications (OAA) Weakly exact von Neumann algebras (I) School MATHEMATICS Weakly exact von Neumann algebras (I) ... 14:00 - 15:00 Weekly SeminarMembrane Remodeling in Cellular Organelles School NANO SCIENCES Membrane Remodeling in Cellular OrganellesMembrane remodeling plays a crucial role in the formation and function of organelles. Prime expamples are the extensive network of tubular structures in the ER and the unusual cup-shaped membranes in autophagy. We investigate the membrane shape remodeling processes establishing and maintaining these structures by using a membrane elastic model combined with explicitly modeled proteins. Our simulations indicate that control of the area-to-volume ratio is a key factor in driving biological membrane shape transitions to form tubular ER 15:30 - 17:00 Geometry and Topology Weekly SeminarOn Curtis Conjecture on Spherical Classes in H_*QS^0 School MATHEMATICS The problem of determining spherical classes in homology of spaces seems to be an elementary problem that one can stated once the Hurewicz map is defined. However, in some cases of interest such as the infinite loop space associated to the sphere spectrum, the answer still is unknown. In this talk, I will start with an introduction to spherical classes and their basic properties, and then state some recent developments in this direction which are obtained by geometric methods. ... 15:30 - 16:30 Weekly SeminarAn Introduction to Ion Sources and Simulation of the ECR Ion Source School PARTICLES AND ACCELERATORS The first stage of many particle accelerators is an ion source, responsible for producing the charged particles and pre-accelerating them to form an ion beam. Ion sources have many applications, not just in the field of scientific studies, but also for medical applications, material processing and surface treatments. In this talk I will explain the physical mechanisms involved in some famous types of ion sources used in accelerator machines. I will also review my past experiences on the research and development of the DC and RF ion sources used in high vacuum coating systems. Finally, I will present preliminary results of the simulation of th ... 16:00 - 18:00 Neuroimaging Journal ClubNeural correlates of evidence accumulation during value-based decisions revealed via simultaneous EEG-fMRI School COGNITIVE SCIENCES Venue: School of Cognitive Sciences, Institute for Research in Fundamental Sciences (IPM), Opposite the ARAJ, Artesh Highway, Tehran, Iran ... |
