This background distribution of tags can be estimated from a background window of fixed width ω centered on the specified segment.
It provides the examiner multiple analyses options such as measuring vessel caliber summary, vessel calibre of examiner specified segment, tortuosity and FD of the image for different regions.
We will define the following variables: 1. mean CIMT, defined as the average of 4 to 8 distances between the far wall lumen-intima and media-adventicia ultrasound interfaces taken bilaterally in each of the specified segments mentioned above, and 2. maximum CIMT, defined as the maximum distance in each segment.
The exact relation between a specified vessel segment and a desired parenchymal target zone is today easily recognized with modern imaging techniques.
The homeobox-containing transcription factors that specify segment identity in arthropods and vertebrates have only a minor function in Dictyostelium development.
The Hox complex is an ancient and highly conserved cluster of related transcription factors that specify segment identity in almost all animals, and originated before the divergence of protostomes and deuterostomes.
abdA, which appears to be activated downstream of DSXF in females and repressed downstream of DSXM in males, is a well-characterized homeotic selector gene that was shown to be important for specifying segment identity [ 47, 48].
Products of the Drosophila HOM-C genes positionally specify segment identity along the anteroposterior axis through independent and combinatorial actions reflecting their spatially restricted expression domains.
Hox genes specify segment identity during development: the unique combination of their expression pattern provides correct positional identity along the anterior-posterior (AP) body axis.
Numerical examples are presented to illustrate the fuel consumption for accomplishing the lunar global targeting from a specified two-segment lunar free-return trajectory.
It is of note that Nv odd stripes 4, 5 and 6 appear to emerge from waves of expression at the posterior of the embryo that likely specify segments A3 A5, which are most sensitive to loss of Nv odd function.
