Nitrosation in the environment: can it occur?
coumarin dissolved in acetone or dichloromethane (1), might nevertheless be expected. A nonvolatile test chemical would still be retained on surfaces exterior to the embryo after evaporation of the solvent. Subsequent imbibition by the seeds in water would then introduce the test chemical into the embryo just as readily as if the test chemical had originally been in aqueous solution. LARRY L. T...

متن کاملWhen can perfect state transfer occur?
Let X be a graph on n vertices with adjacency matrix A and let H(t) denote the matrix-valued function exp(iAt). If u and v are distinct vertices in X, we say perfect state transfer from u to v occurs if there is a time τ such that |H(τ)u,v| = 1. The chief problem is to characterize the cases where perfect state transfer occurs. In this paper, it is shown that if perfect state transfer does occu...

Developmental plasticity describes situations where a specific input during an individual's development produces a lasting alteration in phenotype. Some instances of developmental plasticity may be adaptive, meaning that the tendency to produce the phenotype conditional on having experienced the developmental input has been under positive selection. We discuss the necessary assumptions and pred...
