Considerations for crossover design in clinical study [PDF]
Korean Journal of Anesthesiology, 2021 This article introduces a crossover design that is often used in clinical studies, with the advantage of comparing treatment effects within one study subject.

Study of universality crossover in the contact process [PDF]
Journal of Physics A: Mathematical and General, 2005 We consider a generalization of the contact process stochastic model, including an additional autocatalitic process. The phase diagram of this model in the proper two-parameter space displays a line of transitions between an active and an absorbing phase which starts at the critical point of the contact process and ends at the transition point of the ...

A novel crossover operator for genetic algorithm: Stas crossover [PDF]
Decision Science Letters, 2023 The genetic algorithm (GA) is a natural selection-inspired optimization algorithm. It is a population-based search algorithm that utilizes the concept of survival of the fittest. This study creates a new crossover operator called “Stas Crossover”

A μSR study of the spin-crossover
Journal of Physics and Chemistry of Solids, 2004 The spin-crossover phenomenon is a cooperative low-spin to high-spin transition which can be initiated using temperature or light-irradiation. We have used muon-spin relaxation (μSR) to study this effect in Fe(PM-PEA)2(NCS)2 and Fe(PMAzA)2(NCS)2. We find Gaussian or exponential muon relaxation in the high-spin phase for the two compounds, reflecting ...

Increase of 4-Hydroxybenzoic, a Bioactive Phenolic Compound, after an Organic Intervention Diet
Antioxidants, 2019 Consumption of organic products is increasing yearly due to perceived health-promoting qualities. Several studies have shown higher amounts of phytochemicals such as polyphenols and carotenoids in foods produced by this type of agriculture than in ...

BMC Medical Research Methodology, 2021 Background Case-crossover studies have been widely used in various fields including pharmacoepidemiology. Vines and Farrington indicated in 2001 that when within-subject exposure dependency exists, conditional logistic regression can be biased.

The use of baseline covariates in crossover studies [PDF]
Biostatistics, 2009 It is our experience that in many settings, crossover trials that have within-period baseline measurements are analyzed wrongly. A "conventional" analysis of covariance in this setting uses each baseline as a covariate for the following outcome variable in the same period but not for any other outcome.
