Introduction: Elephant Moraine (EET) 87521 is a polymict mare basalt breccia containing very-low-titanium (VLT) basalt components and rarer KREEP components. [1] showed that within pyroxene from VLT lithic clasts of EET87521, there were two distinct trends in a plot of Ti/(Ti+Cr) versus Fe/(Fe+Mg) (Figure 1). They suggested that the two fractionation trends (A and B) were the result of differen...

Most of the existing commit protocols try to improve the system performance by allowing a committing cohort to lend its data to an executing cohort, thus reducing data inaccessibility. However, these protocols block the borrower when it tries to send WORKDONE/PREPARED message (Qin & Liu 2003, Haritsa, Ramamritham & Gupta 2000, Gupta, Haritsa, Ramamritham & Seshadri 1996, Gupta, Haritsa, & Ramam...
