Non-perturbative matching of Wilson coefficients from four-flavor to three-flavor theories using lattice QCD

The first lattice result for direct CP violation in \(K \to \pi\pi\) decay in the Standard Model published by RBC/UKQCD in 2015 is desired to be more precise to see the deviation from the experimental value more clearly. In this talk, I will overview RBC/UKQCD’s calculation of \(K \to \pi\pi\) matrix elements mentioning a particular error
source: Since RBC/UKQCD calculated the matrix elements with the four-quark operators without the charm quark, we need the
corresponding Wilson coefficients in the three-flavor theory, which can be obtained by converting from the four-flavor theory.
Perturbative matching may result in a significant uncertainty since it
needs to be done below charm threshold. To resolve this problem, we are trying to do this matching in a non-perturbative prescription using lattice QCD. I will explain the strategy of the matching and show some results of an exploratory calculation.

Electronic Structure and Topology in f-Electron Quantum Matter

In recent years there has been a surge of interest in quantum materials with topologically protected properties, which are robust against disorder effects. Interesting examples are topological insulators and three-dimensional Weyl metals. Electronic structure has played an important role in the exotic properties of these materials. In this talk, I will present our recent theoretical study of electronic structure and its topology in f-electron PuB\({}_4\) [1] and Ce\({}_3\)(Pt,Pd)\({}_3\)Bi\({}_4\) [2] compounds. In addition to uncovering topologically nontrivial electronic states, the role of f-electron and in particular the electronic correlation effects are discussed in the framework of density functional theory and its combination with the dynamical mean-field theory.

"Misregulation of splicing factors in breast cancer"
Alternative RNA splicing is a key step in gene expression regulation and contributes to proteomic and functional diversity. Our lab studies the splicing machinery and its misregulation in human tumors, with the goal of identifying novel tumor biomarkers and therapeutic targets.

Dr. Olga Anczukow's lab investigates how changes in RNA splicing contribute to cancer, with the goal of developing novel therapeutic strategies to target splicing alterations and their regulators.
Dr. Anczuków’s interest in RNA splicing started during her Ph.D. at University Claude Bernard Lyon 1 in France. Her research characterized the effect of mutations in breast-cancer-predisposing genes on RNA splicing and stability, and contributed to improving the molecular diagnosis and classification of hereditary breast cancers. As a Postdoctoral Fellow and then Senior Fellow at Cold Spring Harbor Laboratory, NY, she demonstrated that splicing regulators are frequently expressed at high levels in human breast tumors and contribute to cancer initiation and metastasis. Using RNA sequencing and 3D organoid models of breast cancer, she identified and validated novel targets of the oncogenic splicing factor SRSF1. In addition, she demonstrated that RNA-based therapeutics can correct aberrant splicing defects caused by a BRCA2 mutation in hereditary breast cancer. At The Jackson Laboratory, she uses patient-derived organoids, mouse models, and next-generation RNA-sequencing to identify alterations in RNA splicing that contribute to tumor initiation, metastasis, and drug resistance in breast cancer.

EDUCATION
The Institute of Materials Science (IMS) supports over 100 graduate students in three primary fields of study, Materials Science and Engineering, Polymer Science, and Materials Science. In addition, graduate students in affiliated departments use IMS facilities to perform materials-related research.

RESEARCH
IMS provides superior graduate research education in the interdisciplinary fields of materials science and engineering, and provides materials-related technical outreach to Connecticut’s industries. IMS operates and maintains extensive state-of-the-art instrumentation including a wide range of laboratories. Support facilities include an electronics shop and an instrument and machine shop.

Over 100 faculty members from twenty departments including the UConn Health Center are affiliated with IMS, contributing to the Institute’s interdisciplinary research programs. Primary disciplines represented are chemistry, physics, chemical engineering, materials science and engineering, polymer science, pharmacy, molecular and cell biology, mechanical engineering, electrical engineering, biomaterials, and biosciences.

OUTREACH
The Institute is also home to the Industrial Affiliates Program, an industry outreach program which assists Connecticut companies in their research and development efforts to improve new and existing products. The Industrial Affiliates Program provides many benefits for member companies, including access to facilities and faculty at UConn, short courses, and other resources that can assist in materials-related problem solving for industry.
