Recent extreme events such as the devastating 2003 European summer heat wave raise important questions about the possible causes of any underlying trends, or low-frequency variations, in regional climates. Here, we present new evidence that basin-scale changes in the Atlantic Ocean, probably related to the thermohaline circulation, have been an important driver of multidecadal variations in the...
[1] Long-range transport of air across the European and Asian continents brings substantial quantities of ozone and other oxidants to northeast Asia from upwind sources over Europe and North America. This transport differs significantly from that over the Pacific and Atlantic Oceans because of weaker and less frequent frontal systems over the continent and because of weaker convective lifting o...
During a 90-day period in 1994, we measured the availability and connection latency of HTTP (hypertext transfer protocol) information servers. These measurements 'were made from a site in the Eastern United States. The list of servers included 189 servers from Europe and 324 servers from North America. Our measurements indicate that on average, 5.0 percent of North American servers and 5.4 perc...
The deadly poisonous Amanita phalloides is common along the west coast of North America. Death cap mushrooms are especially abundant in habitats around the San Francisco Bay, California, but the species grows as far south as Los Angeles County and north to Vancouver Island, Canada. At different times, various authors have considered the species as either native or introduced, and the question o...
The semi-parasitic European yellow mistletoe (Loranthus europaeus Jacq.) is one of the harmful and damaging factors to the Zagros forests. This study to analyze the causes of infected trees by European yellow mistletoe was conducted in the Ghalajeh forests in Kermanshah province. To carry out this study, completely infected trees were examined by using the tree-to-tree sampling method. Required...
Population structure can provide novel insight into the human past, and recognizing and correcting for such stratification is a practical concern in gene mapping by many association methodologies. We investigate these patterns, primarily through principal component (PC) analysis of whole genome SNP polymorphism, in 2099 individuals from populations of Northern European origin (Ireland, United K...
