Interchanges and statistical designs
Let D be a statistical design consisting of v varieties on b blocks. We say it is binary if a variety occurs at most once on every block. For varieties p and q on blocks x and y respectively, we can obtain design D' from D by interchanging p and q (so p is on y and q is on x). We say that the exchange is binary if either x y, or p q, or: q not on x and p not on y. If D is binary then D' is also...
متن کاملChromosomal Interchanges in Maize.
Chromosomal interchanges, or reciprocal translocations, in maize are of primary interest because of the opportunities they offer for the study of chromosome behavior and crossing over. The great volume of work which has been done on crossing over and on translocations in Drosophila has yielded an abundance of statistical data on crossing over and chromosome distribution. For this type of work D...
متن کاملThe genealogy of genealogy of neurons
Two scenarios of neuronal evolution (monophyly and polyphyly) are discussed in the historical timeline starting from the 19th century. The recent genomic studies on Ctenophores re-initiated a broad interest in the hypotheses of independent origins of neurons. However, even earlier work on ctenophores suggested that their nervous systems are unique in many aspects of their organization and a pos...
متن کاملFloristic Interchanges Between Formosa and the Philippines
THE FLORAS of Formosa and the Philippines are, in spite of the ir geographic proximity , distinctive in their general nature. The tw<? regions wereseparated by the Formosan rift (the Bashi Channel), probably in the early Tertiary, long' before their connections with other respective neighboring areas were severed. Thus the bulk of the Formosan flora was derived from China or from other floras t...
متن کاملA giant graviton genealogy
In this article we extend the construction of giant gravitons from holomorphic surfaces [1] to the ABJM correspondence. We construct a new class of 1 6 -BPS M5-branes wrapping 5-manifolds in S/Zk and supported by a large angular momentum in the orbifold space. These orbifold giant gravitons undergo a supersymmetry enhancement to 1 3 -BPS and 1 2 -BPS configurations in special cases. The compact...
