We present a novel OPT technique for obtaining 3D images of both anatomy and fluorescent-protein expression in vivo, and we apply these techniques to gene expression mapping of Drosophila melanogaster development.

Free-machining a-b brasses are widely used as raw materials for the fabrication of components used in a broad spectrum of technological applications. Their exceptional free-cutting properties are attributed to
various microstructural features of the material ...

The Pearson correlation coefficient (PCC) is regularly used in colocalization measurements, but it is sensitive to image noise. Images of fluorophores are usually degraded by Poisson and background noise and we have found that, even with apparently high quality images, the measured PCC is substantially understated, to the extent that the numbers become misleading ...
