Weekly Seminar
Decision-Making: From Bacteria to Humans

Mehdi Sadeghi


1 JAN 2025
14:00 - 15:00

Life is a set of chemical and physical reactions that occur in a temporal and spatial order and allow a living organism to make decisions. Therefore, we can consider the ability to make decisions by a living organism as its most important feature compared to the non-living world. All living organisms, from single-celled bacteria to humans, have the ability to make decisions, or in other words, choose between the alternatives before them. This ability is due to mechanisms that exist in the living organism and are coded in its genome. When we talk about the behavior of a living organism and its difference from other organisms, we actually mean their different decision-making. With this perspective, I intend to show how living organisms decide which task to do and what they have in common and how the behavior or decision-making mechanism in humans is similar and different from other organisms. What makes us human in this difference is the decision-making algorithm, which, of course, operates in our brain.

This Seminar is free, hybrid, and open to the public.

Hyperbolic Geometry and Continued Fractions

Jafar Shaffaf, Shahid Beheshti University


1 JAN 2025
15:30 - 17:00

In this talk, we are going to uncover a paper written by E. Artin one hundred years ago, in 1924, entitled (in German) "Ein mechanisches System mit quasi-ergodischen Bahnen". "A Mechanical System with Quasi-Ergodic Trajectories " The connection between continued fractions and geodesics in the hyperbolic plane goes back to Humbert (1916) and Smith (1877) and it is used in an ingenious way by E. Artin in the above paper provided the first example of a dense geodesic trajectory on a special Riemann surface, the so-called "modular surface". In the first part of the talk, we will try to cover some preliminaries and generalities about discrete subgroups of the group of isometries of the hyperbolic plane and their relations to the various tessellations of the hyperbolic plane / Poincare disc. In the second part, we will try to talk about a special tessellation called Farey tessellation of the hyperbolic plane and its relation to continued fractions. One of the applications of this connection is the existence of a dense geodesic on the modular surface. If time permits, we will also try to discuss the relationship between the Diophantine approximation of an irrational number and the behavior of the corresponding geodesic on the modular surface.

Cosmic Ray Propagation and Radio-FIR Correlation in IC 342

Mohammad Reza Nasirzadeh

31 DEC 2024
11:00 - 12:30

We will explore a detailed analysis of the radio-far infrared (FIR) correlation in the nearby galaxy IC 342 at an unprecedented 200 pc resolution, using LOFAR LOTSS observations combined with VLA, Herschel, and WISE data. Our multi-frequency study (0.14-4.8 GHz) reveals that while the radio-FIR correlation holds globally, it breaks down at different characteristic scales depending on frequency: ~320 pc at 0.14 GHz versus ~200 pc at 1.4 GHz. This scale-dependent behavior provides direct evidence for cosmic ray electron propagation in the interstellar medium. We find that the nonthermal spectral index flattens at frequencies below 1.4 GHz, a phenomenon observed in both star-forming regions (more pronounced) and diffuse ISM. Our results demonstrate how the detailed analysis of the radio-FIR correlation can serve as a powerful tool for understanding cosmic ray propagation and magnetic field properties in nearby galaxies.

Abstract
We will review the ongoing debates on loop corrections in the multi-phase inflationary universe and their controversial results. Then, we will show that quantum effects can dramatically affect the long CMB-scale modes after regularizing and renormalizing divergences in different stages of inflationary evolution.

IPM Electronics for the CMS phase-2 upgrade of the RPC Link System-Project Annual Review

Dr. Behzad Boghrati - School of Particles and Accelerators, IPM


30 DEC 2024
11:00 - 12:00

Abstract:

In the CMS Muon system, the RPC Link System will upgrade to cope with high luminosity LHC (HL-LHC) conditions and improve the time resolution of the Muon hits detected by the present RPC chambers from 25 ns to 1.5 ns. The upgrade program for the RPC Link System was started in 2017 and endorsed in 2018 by the CMS muon Technical Design Report (TDR). By the end of 2027, the CMS RPC system will install brand-new electronics designed and fabricated by the Tehran IPM. The upgraded RPC Link System consists of several key components: link board (LB), control board (CB), high-speed front panel called Samtec, and control front panel called Harting. For the phase-2 upgrade, 1376 LBs and 216 CBs will be produced. Production of these electronics is split into two phases: pilot production and full production. During the pilot production, only 10% of the boards will be manufactured to ensure the quality of electronics and address any potential failure or complexities in the production process. In this talk, we will review the latest status of the IPM electronics project and explain the following plan for qualification these electronics.

Normal Subgroups in the Automorphism Group of Models of Peano Arithmetic

Saeideh Bahrami, Institute for Research in Fundamental Sciences (IPM)


26 DEC 2024
14:00 - 16:00

It is well-known that the family of automorphisms of any structure constitutes a topological group. In the late 1980s and 1990s, significant progress was made in the understanding of the automorphism group of models of Peano arithmetic (PA). In particular, Richard Kaye provided a landmark characterization of the closed normal subgroups of the automorphism group of a countable recursively saturated model M of PA. His work established an infinite Galois-like correspondence between these closed normal subgroups and invariant initial segments of M. He also conjectured the existence of another correspondence between the non-closed normal subgroups of the automorphism group of M and its invariant initial segments; a conjecture which has remained unproved. In this talk, I will first revisit Kaye�s characterization, and then explore some progress on his conjecture, confirming it in some cases.

25 DEC 2024
09:00 - 17:00

Abstract:

This workshop will delve into cutting-edge developments in particle physics aimed at advancing our understanding beyond the Standard Model (SM). While the SM has provided a robust framework for describing elementary particles and their interactions, evidenced by its success up to TeV-scale energies at the LHC and the 2012 discovery of the Higgs boson by the ATLAS and CMS collaborations, it leaves several profound questions unanswered. The workshop will explore recent theoretical advancements and experimental results from the LHC with a focus on Higgs boson, top quark, and bottom quark physics, alongside pivotal topics in Beyond the Standard Model (BSM) physics, such as dark matter and baryogenesis. By bringing together experts in these fields, the workshop aims to foster discussions on potential extensions of the SM above the electroweak scale, addressing key challenges in particle physics and the search for new phenomena that could illuminate the mysteries of dark matter and the origin of matter-antimatter asymmetry.

Mathematics Colloquium
Affine Lie superalgebras and their representations

Malihe Yousofzadeh, University of Isfahan and IPM


25 DEC 2024
16:00 - 17:00

This talk is based on a project started since 2016 on representations theory of affine Lie superalgebras. The study of representations over affine Lie (super)algebras has a long history; the first attempt in this regard dates back to 1974 when a certain class of modules over affine Lie algebras were studied and classified by the eminent mathematician, Victor Kac. In this talk, we will discuss different classes of modules over an affine Lie (super)algebra and state the difficulties appearing to obtain a classification and that how we can overcome these difficulties.

The MST-Ratio: A New Measure of Mixedness for Colorful Point Sets

Morteza Saghafian, ISTA (Institute of Science and Technology Austria), Klosterneuburg, Austria


25 DEC 2024
14:00 - 15:00

Recently, motivated by applications in spatial biology, we explored the interactions between color classes in a colored point set from a topological perspective. We introduced MST-ratio as a measure for quantifying the mingling of points with different colors. Investigating this measure raises intriguing questions in discrete geometry, which is the primary focus of this talk.
In this talk, I will introduce the concept of the MST-ratio, present the best-known bounds and key complexity results for computing its maximum, and share new findings on its behavior in both random and arbitrary point sets. Finally, I will highlight several open questions in discrete and stochastic geometry that arise from this work.

24 DEC 2024

Abstract:

The first and most important part of the study of star clusters is the detection of reliable members. Two critical conditions for achieving this goal are accurate data and methods that can work with comprehensive data sources. One of the powerful methods for selecting relevant data within a huge data source is machine learning. In the last decade, several research studies have been conducted based on machine learning algorithms for detecting cluster members. In this presentation, we introduce a suitable combination of machine learning algorithms for detecting reliable open cluster members inside and beyond the tidal radius. The tidal radius and the mass segregation are examined for understudied clusters. Finally, we discuss the efficiency of these methods for detecting different structures around star clusters.
