Identification of putative markers linked to grain plumpness in rice (Oryza sativa L.) via association mapping

BMC Genetics, 2017
Background Poor grain plumpness (GP) is one of the main constraints to reaching the yield potential of hybrid rice. Results In this study, the GP of 177 rice varieties was investigated in three locations across 2 years.

Robust statistical methods and the credibility movement of psychological science [PDF]

PeerJ
The general linear model (GLM) is the most frequently applied family of statistical models in psychology. Within the GLM, the effects under study are estimated using the ordinary least squares (OLS) estimation.

Stereoscopic processing of crossed and uncrossed disparities in the human visual cortex

BMC Neuroscience, 2017
Background Binocular disparity provides a powerful cue for depth perception in a stereoscopic environment. Despite increasing knowledge of the cortical areas that process disparity from neuroimaging studies, the neural mechanism underlying disparity sign

GLMdenoise: a fast, automated technique for denoising task-based fMRI data

Frontiers in Neuroscience, 2013
In task-based functional magnetic resonance imaging (fMRI), researchers seek to measure fMRI signals related to a given task or condition. In many circumstances, measuring this signal of interest is limited by noise. In this study, we present GLMdenoise,
