Johnstone, J. (AM) – The Effects of Asymmetry on Overshooting and Magnetic Pumping from Compressible Convection Zones

Engineering 2 Engineering 2 1156 High Street, Santa Cruz
Hybrid Event

We present a comprehensive numerical investigation examining how vertical asymmetry in compressible convection affects overshooting and the transport of large-scale magnetic fields from convective to stably stratified regions. Using three-dimensional direct numerical simulations, we systematically vary the superadiabaticity and stratification of a convective layer to control the vertical asymmetry of the flow and analyze its […]

Yang, J. (CSE) – Towards Controllable and Compositional Generative Vision

Virtual Event

Diffusion-based text-to-image models can generate impressive images, but they largely treat an image as a single, flat output, which makes precise editing of individual elements difficult. This proposal studies layered generative representations that align with professional editing workflows, enabling users to manipulate foreground objects while preserving the rest of the scene. A central focus is […]
