Evolution of longevity improves immunity in Drosophila

Bruno Lemaitre

Much has been learned about the genetics of aging from studies in model organisms, but still little is known about naturally occurring alleles that contribute to variation in longevity. For example, analysis of mutants and transgenes has identified insulin ...

Status Updates in a multi-stream M/G/1/1 preemptive queue

Emre Telatar, Elie Najm

We consider a source that collects a multiplicity of streams of updates and sends them through a network to a monitor. However, only a single update can be in the system at a time. Therefore, the transmitter always preempts the packet being served when a n ...

Spatial variability of potassium in agricultural soils of the canton of Fribourg, Switzerland

Stéphane Joost, Nicolas Rossier, Guillaume Blanchet, André Schneider

Potassium (K) is a crucial element for plant nutrition and its availability and spatial distribution in agricultural soils is influenced by many agro-environmental factors. In Switzerland, a soil monitoring network (FRIBO) was established in 1987 with 250 ...
