Abstract

AbstractThe cDNAs of two opsins (Megopsin1 and Megopsin2) from the vetch aphid, Megoura viciae, have been sequenced and encoded for gene products with 378 and 371 amino acid residues, respectively. Phylogenetic analysis reveals that Megopsin1 falls into the insect long-wavelength opsin group and Megopsin2 is a member of the insect UV-wavelength opsins. Both opsins share the key features of G-protein-coupled receptors and the specific motifs of photopigments. In situ hybridization demonstrated that the transcripts of Megopsin1 and Megopsin2 were expressed in the retinula cells of the compound eyes. [ABSTRACT FROM AUTHOR]

2. Eye don't like it.

Abstract

The article presents the layout for the system of the eye diagram in Great Britain. The figure illustrates the signal measured with a high-bandwidth differential probe at the receiving end of the link. The layout designer wisely chose to keep traces on the top layer, every eye diagram comprises many small segments of the received signal. Unfortunately, the diagram makes a terrible diagnostic tool, it shows aggregate performance but clutters the picture.
