用纵向标记器对间隔审查的故障时间数据进行动态预测

Survival analysis is a statistical method used to analyze time-to-event data, often employed in fields such as medicine, engineering, and social sciences. One of the key challenges in survival analysis is dealing with incomplete data, a phenomenon known as "censoring." Censoring occurs when the event of interest (such as death, relapse, or system failure) has not occurred for some individuals by the end of the study period or is otherwise unobservable, and it might have many different...

Intravital microscopy allows the study of dynamic biological processes such as tissue regeneration and tumor development. The calvarial bone marrow, a highly dynamic tissue, offers insights into hematopoiesis and vascular function. Using a biocompatible 3D-printed head fixation implant allows for repetitive longitudinal imaging, enhancing our understanding of tissue dynamics and the tumor...

Sometimes we want to see how people change over time, as in studies of human development and lifespan. When we test the same group of individuals repeatedly over an extended period of time, we are conducting longitudinal research. Longitudinal research is a research design in which data-gathering is administered repeatedly over an extended period of time. For example, we may survey a group of individuals about their dietary habits at age 20, retest them a decade later at age 30, and then again...

One challenge of analyzing synchronized time-series experiments is that the experiments often differ in the length of recovery from synchrony and the cell-cycle period. Thus, the measurements from different experiments cannot be analyzed in aggregate or readily compared. Here, we describe a method for aligning experiments to allow for phase-specific...

The ValsalvaAnalyzer software includes functions to analyze continuous beat-to-beat electrocardiogram and blood pressure (BP) measurements recorded during the Valsalva maneuver (VM). The computed clinical biomarkers and estimated model outputs provide insight into sympathetic and parasympathetic regulation of heart rate and BP during the...
