Simulating Multi-Subject Momentary Time Sampling
This paper presents software for examining measurement error in Momentary Time Sampling—an interval time sampling method commonly used in research domains (e.g., classroom observations) where continuous recording is not feasible. The Parameters for Optimizing Scientific Sampling Using Momentary-time-sampling Simulator (POSSUMS) produces Monte Carlo simulations (based on user-specified values) a...
متن کاملA comparison of momentary time sampling and partial-interval recording for evaluating functional relations.
In the current study, momentary time sampling (MTS) and partial-interval recording (PIR) were compared to continuous-duration recording of stereotypy and to the frequency of self-injury during a treatment analysis to determine whether the recording method affected data interpretation. Five previously conducted treatment analysis data sets were analyzed by creating separate graphic displays for ...
متن کاملValidation of a genus-specific gene; TPS, used as internal control in quantitative Real Time PCR of transgenic cotton
Identification of genes with invariant levels of gene expression is a prerequisite for validating transcriptomic changes accompanying development. Ideally expression of these genes should be independent of the morphogenetic process or environmental condition.We report here the validation of internal control gene i.e.TPS (trehalose 6-phosphate-synthase) in cotton (Gossypium spp), using TaqMan sy...

An Efficient Implementation of Phase Field Method with Explicit Time Integration
The phase field method integrates the Griffith theory and damage mechanics approach to predict crack initiation, propagation, and branching within one framework. No crack tracking topology is needed, and complex crack shapes can be captures without user intervention. In this paper, a detailed description of how the phase field method is implemented with explicit dynamics into LS-DYNA is provide...
