Rip-NeRF: Anti-aliasing Radiance Fields with Ripmap-Encoded Platonic Solids
Junchen Liu, Wenbo Hu, Zhuo Yang +6
Despite significant advancements in Neural Radiance Fields (NeRFs), the renderings may still suffer from aliasing and blurring artifacts, since it remains a fundamental challenge t…
A Nonparametric Statistical Method for Two Crossing Survival Curves
Xinghui Huang, Jingjing Lyu, Yawen Hou +1
In comparative research on time-to-event data for two groups, when two survival curves cross each other, it may be difficult to use the log-rank test and hazard ratio (HR) to prope…
Dynamic prediction and analysis based on restricted mean survival time in survival analysis with nonproportional hazards
Zijing Yang, Hongji Wu, Yawen Hou +2
In the process of clinical diagnosis and treatment, the restricted mean survival time (RMST), which reflects the life expectancy of patients up to a specified time, can be used as…
Combined tests based on restricted mean time lost for competing risks data
Jingjing Lyu, Yawen Hou, Zheng Chen
Competing risks data are common in medical studies, and the sub-distribution hazard (SDH) ratio is considered an appropriate measure. However, because the limitations of hazard its…
The use of restricted mean time lost under competing risks data
Jingjing Lyu, Yawen Hou, Zheng Chen
Background: Under competing risks, the commonly used sub-distribution hazard ratio (SHR) is not easy to interpret clinically and is valid only under the proportional sub-distributi…
Automatic Segmentation of Non-Tumor Tissues in Glioma MR Brain Images Using Deformable Registration with Partial Convolutional Networks
Zhongqiang Liu
In brain tumor diagnosis and surgical planning, segmentation of tumor regions and accurate analysis of surrounding normal tissues are necessary for physicians. Pathological variabi…
