Anthropogenic effects on watersheds are important in explaining the decline of Pacific Northwest salmon stocks. Associations were tested between thirteen anthropogenic variables in 202 watersheds in Washington, Oregon, Idaho and California and the stock status of summer, spring and fall Chinook Onchorhynchus tshawytsha, coho O. kisutch, and winter steelhead O. mykiss. Summer Chinook had the hig...

Detecting races is important for debugging shared-memory parallel programs , because the races result in unintended nondeterministic executions of the programs. Previous on-they techniques to detect races in programs with nested parallelism cannot guarantee that the race detected rst is not preceded by events that also participate in a race (occurred rst in our terminology). This paper presents...

One hundred thirty-eight isolates of Heterodera glycines from nine states in the United States, People's Republic of China, and Indonesia were tested on the four standard soybean race differentials. A total of 12 variants were found, including the five races described previously. The seven variants that did not correspond to one of the described races and reports from other areas of populations...

Detecting races is important for debugging shared-memory parallel programs, because the races result in unintended nondeterministic executions of the programs. Previous on-they techniques to detect races in programs with inter-thread coordination such as ordered synchronization cannot guarantee that the race detected rst is not preceded by events that also participate in a race. This paper pres...

Detecting data races in multi-threaded programs is a challenging problem in debugging, because the races could reveal nondeterministic program behavior in execution of such programs. Nondeterministic runtime effects of a race are hard to identify and it is difficult to decide whether the reported data races can appear or not in the actual program executions. Previous techniques for detecting ra...

phytophthora root and crown rot of soybean is known as a destructive disease of soy-bean both through out the world and in iran. physiologic races of phytophthora soja were determined in this research and also a fast, accurate and simple method for inoculation of soybean to test race specific resistance. during the years　2001-4, infected soybean plants at different growth stages were collected ...

Roughly speaking, a (data) race on a shared variable arises in a concurrent program if two threads access that variable simultaneously and the accesses are conflicting, that is, at least one of them writes to the variable. Although some races are benign, races often are an indication of bugs. Hence, tools that detect them are invaluable to those writing concurrent programs. Many tools have been...
