We argue in favor of the presumed commit protocol by proposing two new presumed commit variants that significantly reduce the cost of logging activities associated with the original presumed commit protocol. Furthermore, for read-only transactions, we apply our unsolicited updatevote optimizationand show that the cost associated with this type of transactions is the same in both presumed commit...

Experiment 864 at the BNL-AGS was designed to search for exotic states of strange quark matter and other rare composite particles. The experiment was commissioned in 1994 and completed its final run in 1998. Here, we present an overview of the experimental results for the production of light nuclei up to A = 7, antiprotons and antideuterons, hypernuclei and production limits on new states of qu...

background: detection of best predictor of ovarian reserve in patients with temporarily or consistently elevated early follicular phase serum levels of fsh is one of the most important goals in assisted reproductive technique (art). objective: to evaluate whether high level of anti-mullerian hormone level is related to success of art in patients with temporarily or consistently elevated early f...

This paper addresses the scheduling of systems that implement the abort and restart (AR) model. The AR model requires that preempted tasks are aborted. As a result high priority tasks run quickly and shared resources need not be protected (as tasks only work on copies of these resources). However there is significant wastage as low priority tasks may be subject to a series of aborts. We show th...
