Work-stealing is an efficient method to implement load balancing in fine-grained task parallelism. Typically, concurrent deques are used for this purpose. A disadvantage of many concurrent deques is that they require expensive memory fences for local deque operations. In this paper, we propose a new non-blocking work-stealing deque based on the split task queue. Our design uses a dynamic split ...

We derive a lace expansion for the survival probability for critical spread-out oriented percolation above 4+1 dimensions, i.e., the probability θn that the origin is connected to the hyperplane at time n, at the critical threshold pc. Our lace expansion leads to a nonlinear recursion relation for θn, with coefficients that we bound via diagrammatic estimates. This lace expansion is for point-t...

an unimportant amount of time bending over his desk, so that bad positions have not the opportunity of making more or less "staying" faults. But at this time a beginning may be made, either for good or bad. The boy may. be trained to sit correctly at his seat, especially when writing or drawing. lie may be trained to read with his book held before his eyes, not with the book flat upon the desk....

BACKGROUND Unplanned hospital readmissions are common, expensive and often preventable. Strategies designed to reduce readmissions should target patients at high risk. The purpose of this study was to describe medical patients identified using a recently published and validated algorithm (the LACE index) as being at high risk for readmission and to examine their actual hospital readmission rate...

The effects of azalea lace bug, Stephanitis pyrioides (Scott), feeding injury on azalea growth and development were investigated using 'Girard's Rose' azaleas during a 2-yr field study in Georgia Low, medium, and high injury treatments, which corresponded to 6, 8, and 14% maximum canopy area injury, were compared with control azaleas that received no lace bug infestation. Flower number, whole-s...

An undescribed cecidomyiid was discovered in Miami-Dade Co., Florida, during a survey for predators of the avocado lace bug, Pseudacysta perseae (Heidemann), a native pest of avocados, Persea americana , and redbay, Persea borbonia , in the USA. The avocado lace bug was considered a minor pest of avocados until the mid-1990s. Persistent outbreaks of this insect have been observed in Florida and...
