| 11:00 - 12:00 Wednesday Weekly Seminar-google meet Nuclear parton distribution functions with uncertainties in the general mass variable flavor number scheme School PARTICLES AND ACCELERATORS Abstract: The aim of this article is to describe a new set of nuclear parton distribution functions (nuclear PDFs) at next-to-leading order (NLO) and next-to-next-to-leading order (NNLO) accuracy in perturbative QCD. The most commonly used nuclear deep-inelastic scattering (DIS) data analyzed in this study are complemented by the available charged-current neutrino DIS experimental data with nuclear targets. The analysis also incorporates the data from Drell-Yan (DY) cross-section ratios for several nuclear targets. In addition, the most recent DIS data from the Jefferson Lab CLAS and Hall C experiments also added to our data sample. For these ... 13:00 - 16:00 Workshop (online) Google BERT - Pre Training and Fine Tuning for NLP Tasks School COGNITIVE SCIENCES Workshop (online) 13:30 - 15:00 Weekly Seminar (Online) Heavy vs. Light Dark Matter: Theoretical methods and Cosmological Simulations https://www.skyroom.online/ch/soa/weekly-seminar School ASTRONOMY The nature of dark matter is one of the major mysteries in particle physics and cosmology. Among many dark matter scenarios, two prominent candidates are heavy WIMPs and light Axion particles. In this talk, I will start by reviewing some of the theoretical aspects of WIMPs and Axion particles as dark matter candidates. I emphasize the class of axion particles with a mass of about 10^{-22} ev and a de Broglie wavelength of the order of astrophysical distances called Fuzzy dark matter. Then I will discuss the implementation of numerical simulations for both models. In the end, I will present some of the consequences and differences between the ... 14:00 - 15:00 Weekly Webinar Effect of cell-like topography on drug susceptibility of breast cancer cells to doxorubicin School NANO SCIENCES Effect of cell-like topography on drug susceptibility of breast cancer cells to doxorubicin Abstract: This study demonstrates the effect of substrate’s geometrical cues on viability and the efficacy of an anti-cancer drug, doxorubicin (DOX), on breast cancer cells. It is hypothesized that the surface topographical properties can mediate the cellular drug intake. Pseudo-three dimensional (3D) platforms were fabricated using imprinting technique from polydimethylsiloxane (PDMS) and gelatin methacryloyl (GelMA) hydrogel to recapitulate topography of cells’ membranes. The cells exhibited higher viability on the ... 16:00 - 17:30 Theoretical Neuroscience Journal Club (online) Novelty is not Surprise: Human exploratory and adaptive behavior in sequential decision-making School COGNITIVE SCIENCES Organized by: School of Cognitive Sciences to receive the link to join online, please send email to theoretical.neurosci.ipm@gmail.com Abstract: Classic reinforcement learning (RL) theories cannot explain human behavior in response to changes in the environment or in the absence of external reward. Here, we design a deep sequential decision-making paradigm with sparse reward and abrupt environmental changes. To explain the behavior of human participants in these environments, we show that RL theories need to include surprise and novelty, each with a distinct role. While novelty drives explorat ... |
