Okapi is a new causally consistent geo-replicated keyvalue store. Okapi leverages two key design choices to achieve high performance. First, it relies on hybrid logical/physical clocks to achieve low latency even in the presence of clock skew. Second, Okapi achieves higher resource efficiency and better availability, at the expense of a slight increase in update visibility latency. To this end,...

Due to the ever growing applicability of machine translation, estimating the quality of translations automatically has become a necessary task in various scenarios, for example, when deciding whether a machine translation is good enough for human post-editing. This demonstration presents the outcome of a collaborative project between the University of Sheffield and ENLASO, funded by EAMT, the E...

This is the rst participation of the Graduate School of Library and Information Science, University of California at Los Angeles in the TREC Conference. For TREC{2, Category B, UCLA used a version of the Okapi text retrieval system that was made available to UCLA by City University, London, UK. OKAPI has been described in TREC1 (Robertson, Walker, Hancock-Beaulieu, Gull & Lau, 1993a) as well as...

BACKGROUND The capacity of visually oriented species to perceive and respond to visual signal is integral to their evolutionary success. Giraffes are closely related to okapi, but the two species have broad range of phenotypic differences including their visual capacities. Vision studies rank giraffe's visual acuity higher than all other artiodactyls despite sharing similar vision ecological de...

The okapi is an endangered, evolutionarily distinctive even-toed ungulate classified within the giraffidae family that is endemic to the Democratic Republic of Congo. The okapi is currently under major anthropogenic threat, yet to date nothing is known about its genetic structure and evolutionary history, information important for conservation management given the species' current plight. The d...
