Two phase commit (2PC) is used to coordinate the commitment of transactions in distributed systems. The standard 2PC optimization is the presumed abort variant, which uses fewer messages when transactions are aborted and allows the coordinator to forget about aborted transactions. The presumed commit variant of 2PC uses even fewer messages, but its coordinator must do additional logging. We des...

The ECG done on his arrival at the emergency room (see questions) shows (i) sinus tachycardia, (ii) a QRS complex that ends with a positive deflection (or prominent J wave) that is, a rsR9 pattern in V1 and V2, and (iii) an elevated downsloping ST segment ending in a small negative T-wave deflection. This ECG pattern in someone with a history of syncopy and documented ventricular fibrillation/a...

Abstract Between December 2016 and April 2017, a spate of abortions occurred in closed dairy herd from the central eastern region Paraná, Brazil, which 75 cows aborted. To identify its cause, organ fragments were collected an aborted fetus for histopathology, blood samples stillborn, 4 fetuses, 9 farm dogs indirect fluorescent antibody technique (IFAT). These tests found multifocal non-suppurat...
