Using the classical twin design, we assessed genetic, shared environmental, and individual-specific environmental influences on individual differences in the size of 96 brain regions of interest (ROIs).
Then, using the classical twin design, we estimated abnormal white matter heritability and the extent of shared genetic overlap with blood pressure.
Using the classical twin design, this study investigates the influence of genetic factors on the large phenotypic variance in inspection time (IT), and whether the well established IT IQ association can be explained by a common genetic factor.
If the study was to be conducted using the classical RCT design, we should have randomly allocated participants to each mode of delivery.
The aim of the present study was hence to investigate the extent to which traits characteristic of ASC and language ability share genetic and environmental influences with one another using the classical twin design.
We hence tested, using the classical twin design, whether specific dimensional autistic traits, including social difficulties, communication atypicalities and repetitive behaviours, would display differential degrees of aetiological overlap with specific traits of ADHD, including hyperactivity/impulsivity and inattention.
These results are used to characterize the potential loss in efficiency, under various situations, in using the classical optimal designs for this problem.
The amount of copper in the superconducting cable has been defined by using the classical hotspot temperature design criterion that is based on the adiabatic condition.
The set point tracking controller is designed using the classical direct synthesis method based on the process model without considering the time delay.
The performance of this device for heat flux inversion was experimentally tested, proving that it was more efficient than a more complex device designed using the classical transformation thermodynamics approach.
