let $g=(v, e)$ be a graph. by emph{directional labeling (ord-labeling)} of an edge $x=uv$ of $g$ by an ordered $n$-tuple$(a_1,a_2,...,a_n)$, we mean a labeling of the edge $x$ such thatwe consider the label on $uv$ as $(a_1,a_2,...,a_n)$ in thedirection from $u$ to $v$, and the label on $x$ as$(a_{n},a_{n-1},...,a_1)$ in the direction from $v$ to $u$. inthis paper, we study graphs, called emph{...

Abstract This research is the first to produce induced pluripotent stem cell-derived inner ear sensory neurons in Neurog1 +/? heterozygote mouse using blastocyst complementation. Additionally, this approach corrected non-sensory deficits associated with heterozygosity, indicating that complementation specific endogenous function. work validates use of as a tool create novel insight into functio...

Mutations in many genes can result in a similar phenotype. Finding a number of mutants with the same phenotype tells you little about how many genes you are dealing with, and how mutable those genes are until you can assign those mutations to genetic loci. The genetic assay for gene assignment is called the complementation test. The simplicity and robustness of this test makes it a fundamental ...
