Talk & Lecture
Speaker: Arnak DalalyanVenue: Room 1417, Administration Building, Zijingang CampusAbstract: Generative modeling aims to produce new random examples from an unknown target distribution, given access to a finite collection of examples. Among the leading approaches, denoising diffusion probabilistic models (DDPMs) construct such examples by mapping a Brownian motion via a diffusio...

14:00
Talk & Lecture
Speaker: Yafei LiangVenue: Room 426, School of Economics, Zijingang CampusAbstract: This study examines how large language models (LLMs) affect language barriers and disparities in publication outcomes and research impact for English-as-a-Foreign-Language (EFL) scholars. Using the release of ChatGPT-3.5 in November 2022 as a natural experiment, we analyze paper metadata from the Soc...

15:00
Talk & Lecture
Speaker: Kallol RayVenue: Room 203, Haina Building 2, Zijingang CampusAbstract: This work investigates both steady and unsteady nonlinear systems that couple the generalized convective Brinkman-Forchheimer model with a system of advection-diffusion equations, commonly referred to as double-diffusion equations. The existence and uniqueness of weak solutions to the governing equations...

Talk & Lecture
Speaker: Yulei LuoVenue: Room 530, Chengjun Building 7, Zijingang CampusAbstract: Using firm-level data, we document that inventory investment rises with contemporaneous sales shocks and falls with lagged sales shocks. This reversal pattern is inconsistent with standard rational-expectations stock-adjustment models, which imply weak or counterfactual inventory-sales comovement. We s...
