In a distributed system multiple nodes may initiate snapshot collection concurrently. In this paper we present a global snapshot collection algorithm that combines the information collected by each initiator. This generates a maximal, consistent global snapshot that is more recent than the snapshot collected by any initiator. Global snapshots are used to establish checkpoints for recovery from ...

Syntheses of organometallic initiators were conducted under a nitrogen atmosphere using standard Schlenk techniques. All reagents were of commercial grade and obtained from Sigma-Aldrich Co.. Solvents and the propionic acid used for the preparation of initiators were carefully dried and distilled under nitrogen atmosphere prior to use. TEMPO was sublimated and stored under nitrogen atmosphere. ...

By using a two stage model of carcinogenesis, we generated Monte Carlo studies to assess the efficiency and robustness of the 3-poly test for animal carcinogenicity experiments. The Monte Carlo results indicate that the 3-poly test is quite powerful for detecting the carcinogenic effects of complete carcinogens, moderate promoters, and initiators with moderate or large effect, but, in some case...

The iSCSI protocol provides access to SCSI devices over a TCP transport. Using the iSCSI protocol enables one to build a Storage Area Network using standard Ethernet infrastructure and standard networking management tools. This paper outlines how we implemented a family of iSCSI initiators on a common core. The initially supported initiators were on the Windows NT and the Linux Operating System...

The suitability of various peroxide initiators for a radical polymerization-based self-healing system is evaluated. The initiators are compared using previously established criteria in the design of ring opening metathesis polymerizationbased self-healing systems. Benzoyl peroxide (BPO) emerges as the best performing initiator across the range of evaluation criteria. Epoxy vinyl ester resin sam...
