Quantification of scaling exponents and crossover phenomena in nonstationary heartbeat time series.
Chaos, 1995The healthy heartbeat is traditionally thought to be regulated according to the classical principle of homeostasis whereby physiologic systems operate to reduce variability and achieve an equilibrium-like state [Physiol. Rev. 9, 399-431 (1929)]. However,

The case-crossover design: a method for studying transient effects on the risk of acute events.
American Journal of Epidemiology, 1991A case-control design involving only cases may be used when brief exposure causes a transient change in risk of a rare acute-onset disease. The design resembles a retrospective nonrandomized crossover study but differs in having only a sample of the base

Developing Mixed Methods Crossover Analysis Approaches
Journal of Mixed Methods Research, 2020Onwuegbuzie and Hitchcock (2015) provided an initial framework for conceptualizing and conducting advanced-level mixed analysis approaches. In the present article, we build on these efforts by altering the framework to focus on crossover analyses, which ...

Prucalopride in Gastroparesis: A Randomized Placebo-Controlled Crossover Study.
American Journal of Gastroenterology, 2019OBJECTIVES Prokinetics are considered the preferred treatment option for gastroparesis, but evidence of their efficacy is scarce. Prucalopride, a selective 5-hydroxytryptamine 4 receptor agonist used in the treatment of constipation, is able to enhance ...

WIREs Computational Statistics, 2010
AbstractCrossover designs and within‐subject designs are designs where each experimental unit receives a series of treatments over time. Because treatments are assigned at different time points, one must worry about whether there is carryover or residual effects from a treatment given in a previous period to a subsequent period. This article introduces

Superconductivity In conventional superconductors, the electron pairs responsible for superconductivity are large and overlapping. Starting from this so-called Bardeen-Cooper-Schrieffer (BCS) limit, increasing interactions can set the system on a path of crossover to the opposite limit of small, tightly bound electron pairs that undergo Bose-Einstein ...

Dimensional crossover of thermal transport in few-layer graphene.
Nature Materials, 2010Graphene, in addition to its unique electronic and optical properties, reveals unusually high thermal conductivity. The fact that the thermal conductivity of large enough graphene sheets should be higher than that of basal planes of bulk graphite was ...

Advancements in crossover theory
Journal of Managerial Psychology, 2009PurposeThe central aim of this paper is to give an overview of theory and research on the crossover of (work‐related) wellbeing from employees to their partners at home. In addition, it seeks to discuss studies on the crossover of wellbeing from employees to their colleagues in the workplace.
