Logging is crucial to performance in modern multicore main-memory database management systems (DBMSs). Traditional data logging (ARIES) and command logging algorithms enforce a sequential order among log records using a global log sequence number (LSN). Log flushing and recovery after a crash are both performed in the LSN order. This serialization of transaction logging and recovery can limit t...

Understanding the causes underlying changes in species diversity is a fundamental pursuit of ecology. Animal species richness and composition often change with decreased forest structural complexity associated with logging. Yet differences in latitude and forest type may strongly influence how species diversity responds to logging. We performed a meta-analysis of logging effects on local specie...

Pervasive logging devices capture everything along with the public nearby without their consent, thus, possibly troubling people who prefer their privacy. This has issues for privacy and, furthermore, the widespread use of such logging devices may affect people’s behavior, as they may feel uncomfortable that they are constantly being monitored. People may wish to have some control over the life...

The distributed shared memory(DSM) system transforms an existing network of workstations to a powerful shared-memory parallel computer which could deliver superior price/performance. However, with more workstations engaged in the system and longer execution time, the probability of faults increases which could render the system useless. Several checkpointing and logging schemes have been propos...

Primary tropical forests are lost at an alarming rate, and much of the remaining forest is being degraded by selective logging. Yet, the impacts of logging on biodiversity remain poorly understood, in part due to the seemingly conflicting findings of case studies: about as many studies have reported increases in biodiversity after selective logging as have reported decreases. Consequently, meta...

Throughout the 700-yearlong coal exploration period in Ruhr region, an abundance of geological, geophysical, seismic, and situ stress data was obtained from Carboniferous strata. In this study, we take advantage unique dataset to develop a static 3D geomechanical model predict spatially continuous distribution undisturbed state evaluate reactivation risk major fault zones. Compared point-wise i...

At present, great progress has been made in the prediction of undercompaction and fluid expansion overpressure. However, recent years, field frequently encountered pressure relief-type Different from primary overpressure, such as expansion, this type overpressure belongs to secondary which a certain concealment response seismic velocity logging data. Based on this, geological analysis model was...

As a sedimentary mineral, most sandstone type uranium deposits are formed in petroliferous basins. Therefore, we can fully tap the residual economic value of historical logging and 3D seismic data measured for oil gas to search deposits. However, large amount acoustic missing target stratum reservoir that it is not main gas. A reconstructed method based on clustering analysis with low-frequency...
