| 11:00 - 12:00 Wednesday Weekly Seminar - Hybrid Format Using Heavy-Ion Collisions to Investigate Nuclear Structure School PARTICLES AND ACCELERATORS Abstract: The main purpose of heavy-ion collision (HIC) is to create a liberated state of quark and gluon to study the macroscopic state of QCD matter. This includes the transport coefficient of the produced plasma as well as mapping the configuration of QCD degrees of freedom in various phases. To achieve this goal, it is crucial to model different stages after the collision, from the formation of the initial state to the final state and hadronization at freeze-out. In this context, the nuclear structure plays an important role in determining the initial conditions of the collision. Understanding the spatial distribution of nu ... 14:00 - 15:00 Combinatorics and Computing Weekly Seminar Proof of a Conjecture of Cavenagh, Hamalainen, Lefevre, and Stones School MATHEMATICS An $r imes r$ {it $lambda$-Latin square} ({it rectangle}, respectively) is an $r imes r$ array in which each cell contains a multiset of $lambda$ elements from the set ${1,dots,r}$ of symbols such that each symbol occurs exactly $lambda$ times (at most $lambda$ times, respectively) in each row and column. Cavenagh, Hämäläinen, Lefevre, and Stones asked for conditions that ensure a simple λ-Latin rectangle can be extended to a simple λ-Latin square. We solve this problem in a more general setting by allowing the number of occurrences of each symbol to be prescribed. Cavenagh et al. also conjectured that for each r,λ there exi ... 16:00 - 17:00 Mathematics Colloquium Secret Sharing Schemes School MATHEMATICS Secret sharing is a cryptographic concept introduced in 1979. In a secret sharing scheme, a secret is distributed among a set of participants by giving each one a share. The shares are computed by applying a public rule to the secret and some randomness. Only certain pre-specified subsets of participants are qualified to recover the secret, while the secret remains hidden from all other subsets. Secret sharing is significant from both theoretical and practical perspectives. In this talk, I will survey our results from 2018 to 2024 and introduce several open problems.

Venue: Online Link https://www.skyroom.online/ch/schoolofphysics/colloquium Abstract In this talk, I will start with a brief introduction of the two statistical approaches for probabilistic inference, namely, the frequentist and the Bayesian methods. Then, I will bridge between them by asking how the frequentist inference may be understood from the Bayesian perspective. If time permits, I turn to a discussion on "forecasting" (whic ... |
