Linear analysis of the Kelvin-Helmholtz instability in relativistic magnetized symmetric flows
Anthony Chow, Michael E. Rowan, Lorenzo Sironi +3
We study the linear stability of a planar interface separating two fluids in relative motion, focusing on the symmetric configuration where the two fluids have the same properties…
Neural Intersection Function
Shin Fujieda, Chih-Chen Kao, Takahiro Harada
The ray casting operation in the Monte Carlo ray tracing algorithm usually adopts a bounding volume hierarchy (BVH) to accelerate the process of finding intersections to evaluate v…
Progressive Material Caching
Shin Fujieda, Takahiro Harada
The evaluation of material networks is a relatively resource-intensive process in the rendering pipeline. Modern production scenes can contain hundreds or thousands of complex mate…
DiffProtect: Generate Adversarial Examples with Diffusion Models for Facial Privacy Protection
Jiang Liu, Chun Pong Lau, Zhongliang Guo +3
The increasingly pervasive facial recognition (FR) systems raise serious concerns about personal privacy, especially for billions of users who have publicly shared their photos on…
Particle-in-Cell Simulations of Relativistic Magnetic Reconnection with Advanced Maxwell Solver Algorithms
Hannah Klion, Revathi Jambunathan, Michael E. Rowan +7
Relativistic magnetic reconnection is a non-ideal plasma process that is a source of non-thermal particle acceleration in many high-energy astrophysical systems. Particle-in-cell (…
