In biomedical studies where patient risk is known to increase over time, estimating the baseline survival function under the Cox proportional hazards (PH) model becomes particularly challenging when data involve delayed entry (left truncati...
Enhancing Team Science by Training Collaborative Biostatisticians to have a Strong Statistical Voice [0.03%]
通过培训具有强大统计声音的合作生物统计学家来增强团队科学能力

Rigorous and transparent research practices are essential for trustworthy scientific findings, particularly in observational studies where data-driven analyses carry risks of questionable research practices. This paper introduces a statisti...
More than presence-absence; modelling (e)DNA concentration across time and space from qPCR survey data [0.03%]
浓度先行：时空视角下的(e)DNA浓度模型构建及其qPCR调查数据应用
Milly Jones,Eleni Matechou,Diana Cole et al.
Milly Jones et al.
Environmental DNA (eDNA) surveys offer a revolutionary approach to species monitoring by detecting DNA traces left by organisms in environmental samples, such as water and soil. These surveys provide a cost-effective, non-invasive, and high...
A Weighted Survival Regression Framework for Incorporating External Prediction Information [0.03%]
一种新的加权生存回归框架：利用外部预测信息提高生存分析性能

In discrete choice experiments, the information matrix depends on the model parameters. Therefore designing optimally informative experiments for arbitrary initial parameters often yields highly nonlinear optimization problems and makes opt...
Applications of Deep Neural Networks with Fractal Structure and Attention Blocks for 2D and 3D Brain Tumor Segmentation [0.03%]
具有分形结构和注意模块的深度神经网络在2D和3D脑肿瘤分割中的应用
Kaiming Cheng,Yueyang Shen,Ivo D Dinov
Kaiming Cheng
In this paper, we propose a novel deep neural network (DNN) architecture with fractal structure and attention blocks. The new method is tested to identify and segment 2D and 3D brain tumor masks in normal and pathological neuroimaging data....
