μFork: Supporting POSIX fork Within a Single-Address-Space OS
Single-address-space operating systems have well-known lightweightness benefits that result from their central design idea: the kernel and applications share a unique address space. This model makes these operating systems (OSes) incompatible by design with a large class of software: multiprocess POSIX applications. Indeed, the semantics of the primitive used to create POSIX processes, fork, are inextricably tied to the existence of multiple address spaces. Prior approaches addressing this is…

Graph neural networks for learning liquid simulations in dynamic scenes containing kinematic objects
Simulating particle dynamics with high fidelity is crucial for solving real-world interaction and control tasks involving liquids in design, graphics, and robotics. Recently, data-driven approaches, particularly those based on graph neural networks (GNNs), have shown progress in tackling such problems. However, these approaches are often limited to learning fluid behavior in static free-fall environments or simple manipulation settings involving primitive objects, often overlooking complex inte…

Quaternionic MUBs in H^2 and their reflection symmetries
We consider the primitive quaternionic reflection groups of type P for H^2 that are obtained from Blichfeldt's collineation groups for C^4.These are seen to be intimately related to the maximal set of five quaternionic mutually unbiased bases (MUBs) in H2 , for which they are symmetries. From these groups, we construct other interesting sets of lines that they fix, including a new quaternionic spherical 3-design of 16 lines in H^2 with angles {1/5,3/5}, which meets the special bound. Some inter…

DataWink: Reusing and Adapting SVG-based Visualization Examples with Large Multimodal Models
Creating aesthetically pleasing data visualizations remains challenging for users without design expertise or familiarity with visualization tools. To address this gap, we present DataWink, a system that enables users to create custom visualizations by adapting high-quality examples. Our approach combines large multimodal models (LMMs) to extract data encoding from existing SVG-based visualization examples, featuring an intermediate representation of visualizations that bridges primitive SVG an…
