TenonOS: A Self-Generating LibOS-on-LibOS Framework for Time-Critical Embedded Operating Systems

Xinkui Zhao, Yifan Zhang, Haidan Zhao, Hao Ran Zhang et autres

The growing complexity of embedded systems creates tension between rich functionality and strict resource and real-time constraints. Traditional monolithic operating system and hypervisor designs suffer from resource bloat and unpredictable scheduling, making them unsuitable for time-critical workloads where low latency and low …

Removal of 2-Methyl-4-Isothiazolin-3-One by VUV/UV/Persulfate for Sustainable Wastewater Reclamation: Effects of Inorganic Anions on the Concentrations and Contributions of Hydroxyl Radicals and Sulfate Radicals

Yifan Zhang, Hongwei Xu, Nan Huang

The non-oxidizing antimicrobial 2-Methyl-4-Isothiazolin-3-one (MIT) poses a significant environmental risk given its frequent detection in municipal wastewater. This study showed that the combination of Vacuum UV/UV (VUV/UV) and persulfate (PDS) efficiently achieved the rapid transformation and removal of 10 μM MIT within …

Transient Stability Study of Grid-Forming Energy Storage Converters Based on Mixed Potential Function

Meng Sun, Qianjin Zhang, Chengqiang Yin, Lin Zhang et autres

In the study of grid-forming energy storage converters, simplified modeling of high-order nonlinear systems is critical for large-signal stability (LSS) analysis. However, existing approaches predominantly rely on single mathematical frameworks, which struggle to simultaneously capture multi-timescale coupling characteristics and accurately represent nonlinear …

STS MICCAI 2023 Challenge: Grand challenge on 2D and 3D semi-supervised tooth segmentation

Yaqi Wang, Yifan Zhang, Xiao-Diao Chen, Shuai Wang et autres

Computer-aided design (CAD) tools are increasingly popular in modern dental practice, particularly for treatment planning or comprehensive prognosis evaluation. In particular, the 2D panoramic X-ray image efficiently detects invisible caries, impacted teeth and supernumerary teeth in children, while the 3D dental cone …

Network Threshold Games

Alastair Langtry, Sarah Taylor, Yifan Zhang

This paper proposes a new lens for studying threshold games played on networks when the thresholds are heterogeneous. These are games where agents have two possible actions, and prefer action 1 if and only if enough of their neighbours choose action 1. …
