Provided are techniques for collaborative learned scoping to extend data reach for a search request. From monitoring prior collaboration data of entities discussing topics, the topics, access response times to data sources with content objects for the topics, and topic response content of the content objects are derived. A data reach model is built using the topics, the access response times, the topic response content, and data sources of the topics. For a topic of the topics, the data reach model is used to determine a new data source to be added and a duration of adding the new data source based on real time entity activity. The new data source is added to a data reach of the current group of entities. In response to receiving a search request, the search request is issued against the data sources and the new data source, and results are returned. |

Optimized execution of queries involving early terminable database operators
According to embodiments, a multi-node database management system allows consumer processes (“consumers”) implementing a portion of a distributed data-combination operation to independently send a STOP notification to corresponding producer processes (“producers”). Upon a given consumer determining that the consumer requires no further information from corresponding producers, the consumer sends a STOP notification to the producers. When a given consumer sends out a STOP notification, the producers drop any data destined for the given consumer and also stops preparing data for and sending rows to the given consumer. Furthermore, once the producers receive STOP notifications from all of the consumers corresponding to the producers, the producers stop the current sub plan execution immediately without requiring completion of the sub plan. Thus, embodiments significantly improve the query execution performance by avoiding scanning and distributing data that is not needed for execution of the distributed operation. |

The methods comprise a first round of TPP, including mixing a cell lysate comprising a virus with ammonium sulfate and t-butanol, and separating the mixture, thereby forming a first aqueous phase, a first organic phase, and a first interphase. The first aqueous phase can comprise the virus, which can be subjected to a second round of TPP, resulting in a second aqueous phase, a second organic phase, and a second interphase. The second interphase can comprise highly purified virus. The methods can comprise subjecting a first aqueous phase to further purification by column chromatography or density gradient centrifugation. Purification of AAV, including AAV2, AAV5 and AAV6, from lysates of infected insect cell cultures is demonstrated. TPP-purified AAV particles infect at least as well as those prepared by standard methods. |

Customizable accelerated aging for distilled spirits
Methods, systems, and apparatuses for the accelerated aging of beverages, including distilled spirits are disclosed. A spirit is aged through a modular approach that targets development of individual sensory characteristics. In one embodiment, a spirit undergoes ultrasonic cavitation in the presence of wood chips, heating in the presence of wood chips, ultrasonic cavitation without wood chips, heating without wood chips, and intermittent aeration. The process is operable to produce a highly customized spirit and achieve a taste, bouquet, and color similar to that of traditionally aged spirits. |
