Generalized snapshot isolation extends snapshot isolation as used in Oracle and other databases in a manner suitable for replicated databases. While (conventional) snapshot isolation requires that transactions observe the “latest” snapshot of the database, generalized snapshot isolation allows the use of “older” snapshots, facilitating a replicated implementation. We show that many of the desir...

there are much heterogeneity in the genetic variation of type 2 diabetes (t2d). the purpose of this study was to investigate the association of seven novel genetic loci identified in a recent genome-wide association studies (gwas) with t2d in chinese dong populations.a case-controlled study was performed in individuals of chinese dong nationality. the genotypes of pard3b (rs849230), loc729993 (...

Omentectomy is usually indicated for an oncological viewpoint, but in case of signs omental ischemia, necrosis and infection acute omentectomy can be a lifesaving procedure.

Checkpoint-rollback recovery, which is a universal method for restoring distributed systems after faults, requires a sophisticated snapshot algorithm especially if the systems are large-scale, since repeatedly taking global snapshots of the whole system requires unacceptable communication cost. As a sophisticated snapshot algorithm, a partial snapshot algorithm has been introduced that takes a ...

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 ...
