In a study replicated across two states and two years, we tested the sublethal effects on honey bees of the miticides Apistan (tau fluvalinate) and Check Mite+ (coumaphos) and the wood preservative copper naphthenate applied at label rates in field conditions. A continuous covariate, a colony Varroa mite index, helped us disambiguate the effects of the chemicals on bees while adjusting for a pr...

The neuroimmune events leading to human immunodeficiency virus (HIV)-1-associated dementia (HAD) are linked to macrophage secretory neurotoxins (cellular and viral toxins). To study such events, we developed a murine model of HIV-1 encephalitis (HIVE), the pathological equivalent of HAD. Severe combined immunodeficient (SCID) mice injected with HIV-1-infected monocyte-derived macrophages (MDMs)...

The trace consists of cell information of about 29 days spanning across 700k jobs. This paper deals with statistical analysis of this cluster trace. Since the size of trace is very large, Hive which is a Hadoop distributed file system (HDFS) based platform for querying and analysis of Big data, has been used. Hive was accessed through its Beeswax interface. The data was imported into HDFS throu...

Large scale data set provides the better opportunity to find out much better data relationship in the area of business intelligence. In the paper, we implement our systems using Hadoop that has been popular to store and compute Big Data. However, it is not easy to write Hadoop Map Reduce code. Therefore, we use Hive and Hive QL codes to understand the relationships between ratings and the users...

Worker honeybees (Apis mellifera capensis) encapsulate the small hive beetle (Aethina tumida), a nest parasite, in propolis (tree resin collected by the bees). The encapsulation process lasts 1–4 days and the bees have a sophisticated guarding strategy for limiting the escape of beetles during encapsulation. Some encapsulated beetles died (4.9%) and a few escaped (1.6%). Encapsulation has proba...

As honey bee workers switch from in-hive tasks to foraging, they undergo transition from constant exposure to the controlled homogenous physical and sensory environment of the hive to prolonged diurnal exposures to a far more heterogeneous environment outside the hive. The switch from hive work to foraging offers an opportunity for the integrative study of the physiological and genetic mechanis...
