The straying of hatchery salmon may harm wild salmon populations through a variety of ecological and genetic mechanisms. Surveys of pink (Oncorhynchus gorbuscha), chum (O. keta) and sockeye (O. nerka) salmon in wild salmon spawning locations in Prince William Sound (PWS), Alaska since 1997 show a wide range of hatchery straying. The analysis of thermally(More)
We hypothesized that differences in microbial and plant N demand in balsam poplar and white spruce stands would control in situ net N transformation and retention following N additions. Throughout the study, N fertilizer (NH 4 NO 3) was added in three increments during the growing season, giving an annual N addition of 100 kg ha À1 yr À1. In balsam poplar,(More)
In this paper we describe the status of the first prototype of the 60 GHz wireless Multi-gigabit data transfer topology currently under development at University of Heidelberg using IBM 130 nm SiGe HBT BiCMOS technology. The 60 GHz band is very suitable for high data rate and short distance applications. One application can be a wireless multi Gbps radial(More)
The average sizes of Pacific salmon have declined in some areas in the Northeast Pacific over the past few decades, but the extent and geographic distribution of these declines in Alaska is uncertain. Here, we used regression analyses to quantify decadal trends in length and age at maturity in ten datasets from commercial harvests, weirs, and spawner(More)
The planned upgrade of the Large Hadron Collider, the HL-LHC, will increase the already excessive rates from the ATLAS first level (L1) trigger. The proposed increased luminosity is about five times higher than the design luminosity. This will increase the number of pileup collisions in each event. This means that the L1 trigger must achieve a higher(More)
Floristic succession in the boreal forest can have a dramatic influence on ecosystem nutrient cycling. We predicted that a decrease in plant and microbial demand for nitrogen (N) during the transition from mid- to late-succession forests would induce an increase in the leaching of dissolved inorganic nitrogen (DIN), relative to dissolved organic nitrogen(More)
