Speaker: Jiayu Li, University of Science and Technology of ChinaVenue: 210 Haina Complex Building 2， Zijingang CampusAbstract: In the talk we will review PDE methods in geometric analysis, mainly Li Yau gradient estimates, Sacks-Uhlenbeck blow-up analysis, and the geometric flow method. We will also talk our results in the fields.

Speaker: Zhipei LiangVenue: Lecture Theater East 102/103, Haining CampusAbstract: Scientific research requires powerful tools for clucidating the secrets of nature. Today, understanding the brain — how itworks and what goes wrong when it is injured or diseased—is considered one of the last frontiers in science, and it has posed significant challenges for scientists and engineers to develop effective tools to meet this objective.Since its invention in the early 1970s, magnetic resonance imaging (MRI) has revolutionized radiology, neuroscience andmedicine.And yet, the magnetic resonance phenomenon (often known as spin in physics) has never ceased to amaze those inthe field with new capabilities emerging every few years. Recent synergistic integration of AI with MRI is transforming the field and producing unprecedented imaging capabilities to unravel the mystery of the brain. This talk will give an overview of the major scientific discoveries and technical innovations behind the development of MRI and discuss new exciting opportunities available to develop next-generation AI-powered MRI systems.

Speaker: Andrew T. ForcehimesVenue: Chengjunyuan, Building 4, Room 311Time: 27th December, 2024 14:00Abstract:Reasonableness lies at the heart of normativity. To claim that you are being reasonable is to claim that you have lived up to the standards of reason. To claim that you are being unreasonable is to claim that you have not. Yet not everything is open to assessments of reasonableness. The actions and attitudes of cognitively unsophisticated animals are neither reasonable nor unreasonable. They are areasonable, falling outside the domain of reason. This talk is concerned with locating and explaining this boundary. The view I aim to defend holds that something is assessable for reasonableness if and only if and because it is the functional effect of reasoning.

Speaker:Shiyang Ma (Shanghai Jiaotong University)Venue: Zijingang Campus, Administration Building, Room 1417Time: 20th December, 2024 14:00Abstract: Local genetic correlation analysis is an important tool for identifying genetic loci with shared biology across traits. Recently Border et al. have shown that the results of these analyses are confounded by cross-trait assortative mating (xAM) leading to many false positive findings. Here we describe LAVA-Knock, a local genetic correlation method that builds off an existing genetic correlation method, LAVA, and augments it by generating synthetic data in a way that preserves local and long-range linkage disequilibrium (LD), allowing us to reduce the confounding induced by xAM. We show in simulations based on a realistic xAM model and in GWAS applications for 630 trait pairs that LAVA-Knock can greatly reduce the bias due to xAM relative to LAVA. Furthermore, we show a significant positive correlation between the reduction in local genetic correlations and estimates in the literature of cross-mate phenotype correlations; in particular, pairs of traits that are known to have high cross-mate phenotype correlation values have a significantly higher reduction in the number of local genetic correlations compared with other trait pairs. A few representative examples include education and intelligence, education and alcohol consumption, and attention-deficit hyperactivity disorder and depression. These results suggest that LAVA-Knock can reduce confounding due to both short range LD but also long-range LD induced by xAM.
