Generalized geometric cubic splines [PDF]

, 1996
A constructive approach has been adopted to build interpolatory and freeform cubic spline curves with a more general continuity than -continuity. This method provides not only a large variety of very interesting shape controls like biased, point and ...

Temperature and heat‐load exposure effects on preterm births: Insights from a population‐based study using distributed lag non‐linear models

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective Preterm birth presents a substantial health, psychological, and economic burden worldwide. Environmental factors, including temperature fluctuations, are known to influence the risk of preterm birth. This study aimed to investigate the association between high temperatures and heat load and preterm births. Methods Using a time‐series

Nonlinear Relations Between Resting Heart Rate Measures and Health Risk Behavior in Emerging Adulthood

Journal of Adolescence, EarlyView.
ABSTRACT Introduction Resting heart rate (HR) measures reflect autonomic processes that could predict health risk behavior (HRB) in emerging adulthood when risky behavior is prominent. However, prior studies and extant theories are inconsistent, such that the relationships between HR measures and HRB could be positive or negative in direction.
