Cannabis is one of the most commonly used illicit drugs, and its effects have traditionally been seen as less harmful than outcomes associated with the highly prevalent use of alcohol and other illicit substances (e.g., cocaine and amphetamines), and injecting drugs. Consequently, less attention has been focused on developing and evaluating interventions in(More)
observable in molecular beam experiments of angular distributions for this reaction at energies well below that of the conical intersection (8). However, other calculations that did not account for the geometric phase gave good agreement with measured angular distributions for this reaction at the same collision energies, which suggests that the effect(More)
This paper outlines a numerical scheme for accurate, detailed, and high-throughput image analysis of plant roots. In contrast to existing root image analysis tools that focus on root system-average traits, a novel, fully automated and robust approach for the detailed characterization of root traits, based on a graph optimization process is presented. The(More)
Large, longitudinal, multivariate population surveys are increasingly common. Many analytic methods inspect changing rates of individual outcomes but ignore heterogeneous subpopulations that may exist. In this document I propose two analytical methods which extend group-based trajectory models to multivariate outcomes. I use group-based longitudinal finite(More)
In this paper we report on development and analysis of a high throughput 3D reconstruction set-up for reconstructing cereal plants grown in pots for their phenotypic analysis. We are motivated with the idea of accurate and high-throughput reconstruction of shoots. We have developed a turntable setup for high-throughput and high accuracy 3D reconstruction of(More)
1 Abstract We report a new resummation procedure for the partial wave series (PWS) representation of the scattering amplitude, when a basis set of Legendre poly-nomials is used for the expansion. The effect of the resummation is to remove from the PWS the factor (α + β cos θ) −r where θ is the scattering angle, α and β are constants and r = 1, 2, 3, ....(More)
