Born in 1938, Lynn was intellectually precocious, earning her bachelor’s degree from the University of Chicago at age 18 and a Berkeley PhD 6 years later. Lynn’s enduring place in science was earned soon thereafter, with the publication of her theory of endosymbiosis...
متن کاملHans Meinhardt (1938–2016)
The famous theoretical biologist Hans Meinhardt died on 11 February 2016 in Tübingen. Meinhardt is well known for mathematical models of biological pattern formation, which he applied to a wide range of problems in developmental biology such as body axis formation, segmentation, limb patterning, regeneration, phyllotaxis and surface patterns — most famously the color patterns on seashells. Hans...

Todetermine useful metrics for assessing streamwater quality in the Southeastern Coastal Plain, we examined differences among two buffered and three unbuffered streams in an agricultural landscape in southwestern Georgia. Potential indicators included amphibian diversity and abundance, aquatic macroinvertebrate populations, riparian vegetative structure, water quality, and stream physical param...
متن کاملA Poisson-Charlier approximation for nonstationary queues
In this paper, we develop a new approximation for nonstationary multiserver queues with abandonment. Our method uses the Poisson–Charlier polynomials, which are a discrete orthogonal polynomial sequence that is orthogonal with respect to the Poisson distribution. We show that by appealing to the Poisson–Charlier polynomials that we can estimate the mean, variance, and probability of delay of ou...

of the nitrogen cycling has major consequences for other biogeochemical processes and ecosystem functions and services, Voss says. Recent research has uncovered an apparent imbalance in the nitrogen budget of the oceans, which isn’t completely understood yet and may point to additional processes that remain to be discovered. The traditional view that bacterial denitrification is the only signif...
