A method is presented that uses a vectorial multiscale feature image for wave front propagation between two or more user defined points to retrieve the central axis of tubular objects in digital images. Its implicit scale selection mechanism makes the method more robust to overlap and to the presence of adjacent structures than conventional techniques that propagate a wave front over a scalar image representing the maximum of a range of filters. The method is shown to retain its potential to cope with severe stenoses or imaging artifacts and objects with varying widths in simulated and actual two-dimensional angiographic images.

Generational diversity and team innovation: the roles of conflict and shared leadership.
Front Psychol

School of Business, Macau University of Science and Technology, Taipa, Macau SAR, China.
The increasing generational diversity in modern teams has sparked an ongoing debate about its impact on team performance. Grounded in decision-making and social identity theories, this study explores the multifaceted relationship between generational diversity and team innovation performance, examining the mediating roles of cognitive and affective conflicts and the moderating role of shared leadership. The findings from a three-wave survey of five multi-generational teams in a Chinese organization reveal that generational diversity predicts both cognitive and affective conflicts, which subsequently exert opposing effects on team innovation.

Neuromuscular factors predicting lower limb explosive strength in male college sprinters.
Front Physiol
January 2025
Sports Science School, Beijing Sport University, Beijing, China.
Purpose: This study aimed to explore the effects of neural and muscular factors on lower limb explosive strength in male college sprinters, and build models based on those factors to identify the key neuromuscular factors that predict the rate of force development (RFD) and 30 m sprint time.
Method: 15 male college sprinters were recruited in this study, with 100 m personal best times under 10.93 s.
Early-life famine exposure and subsequent risk of chronic diseases in later adulthood: a population-based retrospective cohort study.
Front Public Health
January 2025
School of Physical Education, Shanxi Normal University, Taiyuan, China.
Background: Over the past few decades, China has experienced significant demographic and epidemiological changes. The sharp decline in fertility and mortality rates has accelerated population aging, contributing to an increase in the prevalence of chronic diseases. The nutritional condition during early life is associated with the onset of chronic illnesses later in adulthood.
