This lecture explores the stability of viscous incompressible fluids driven by buoyancy, using the Boussinesq equations as a mathematical model. The speaker will introduce a class of stationary fluid states with a strictly increasing background temperature and investigate how the fluid behaves under small perturbations of these states.

Effective pipeline leak detection and localization are essential for mitigating greenhouse gas emissions in hydrocarbon transportation systems. However, the complex spatiotemporal dynamics, limited sensor coverage, and measurement disturbances pose significant challenges. This talk presents advanced estimation and control strategies designed for pipeline networks modeled by infinite-dimensional systems governed by partial differential equations (PDEs).

Dr. Richard Zhang is Director of the Center for Power Electronics Systems (CPES), the Hugh P. and Ethel C. Kelly Chair Professor in the Bradley Department of Electrical and Computer Engineering at Virginia Tech, and an IEEE Fellow.

Tim Burness is a Professor of Pure Mathematics at the University of Bristol in the UK, where he currently serves as Director of the Institute for Pure Mathematics. Tim works in group theory and related areas, specializing in the study of finite and algebraic simple groups, and the application of probabilistic and computational methods.

Sumit Agarwal is a distinguished professor and thought leader in the fields of finance, economics, and real estate, currently serving as the Low Tuck Kwong Distinguished Professor of Finance, Economics, and Real Estate at the National University of Singapore (NUS). He is the Managing Director of the Sustainable and Green Finance Institute, Head of the Department of Real Estate, and President of the Asian Bureau of Finance and Economic Research.

We estimate the ecological costs of corporate toxic emissions using managerial pressure to meet earnings benchmarks as an instrument for toxic releases. Linking plant-level emissions to millions of U.S. birdwatching records from 2002–2018, we examine changes in local bird populations around manufacturing facilities owned by U.S. public firms.

In this talk, I will introduce the key definitions and I will discuss some of the main methods we use to study subgroup regularity. I will then present some recent results obtained with my PhD student Marina Anagnostopoulou-Merkouri, and I will also discuss work with Hongyi Huang on the regularity of nilpotent subgroups of simple groups, and joint work with Lei Wang on the regularity of irreducible subgroups of classical groups.

Huang Ling, currently an associate professor of economics at the University of Connecticut, graduated from Duke University, with research areas including environmental economics and industrial organization. Professor Huang Ling is committed to designing more effective policies by mining large-scale microdata, with a particular focus on the evaluation of environmental policy effectiveness and the impact of individual strategic behavior.

Neural activities in the human brain exhibit multiple different timescales, such as the duration of neural information processing, which are referred to as Intrinsic Neural Timescales (INT). Previous studies have found that INT display a hierarchical topological structure in the human brain, ranging from sensory regions to higher-order cognitive regions. However, the specific mechanisms by which INT contribute to consciousness remain to be further elucidated.
