Abstract: An apparatus for producing Pb-212. The apparatus comprises an emanation box that comprises an emanation source comprising a porous non-reactive material. The emanation box receives at least one of Th-228 and Ra-224, wherein the at least one of Th-228 and Ra-224 decays to Rn-220 within the emanation box. The apparatus further includes a carrier gas feed coupled to the emanation box. The carrier gas feed directs an inert gas into the emanation box and the inert gas carries the Rn-220 out of the emanation box through a carrier gas exit port of the emanation box. The apparatus also includes one or more Rn-220 targets coupled to the carrier gas exit port. The carrier gas carries the Rn-220 from the emanation box to the one or more Rn-220 targets and the Rn-220 decays into Pb-212 within the one or more Rn-220 targets. The Pb-212 is directed into the Pb-212 collection container.

Abstract: Techniques for using online engagement footprints for video engagement prediction are provided. In one technique, events are received from multiple client devices, each event indicating a type of engagement of a video item from among multiple types of engagement. One or more machine learning techniques are used to train a prediction model that is based on the events and multiple features that includes the multiple types of engagement. In response to receiving a content request, multiple entity feature values are identified for a particular entity that is associated with the content request. Two or more of the entity feature values correspond to two or more of the types of engagement. A prediction is generated based on the entity feature values and the prediction model. The prediction is used to determine whether to select, from candidate content items, a particular content item that includes particular video.

The method includes a step of securing a first pipe segment of the pipeline segments at a top end of the conduit, a step of aligning a main axis of a second pipe segment of the pipeline segments with the main axis of the pipeline, a step of lifting the second pipe segment from a first position associated with a bottom end of the conduit to a second position adjacent to the first pipe segment, a step of abutting a top rim of the second pipe segment against a bottom rim of the first pipe segment, and a step of attaching the top rim of the second pipe segment to the bottom rim of the first pipe segment.

Abstract: A method for producing Pb-212 isotope comprises introducing Th-228 into an emanation box. The emanation box comprises an emanation source comprising a high-surface area material. The method also includes introducing a carrier gas into the emanation box through a carrier gas feed. The method also includes separating the Rn-220 from the carrier gas in the one or more Rn-220 targets, directing the carrier gas out of the one or more Rn-220 targets through a carrier gas exhaust port, directing a liquid through a liquid feed into the one or more Rn-220 targets, and allowing the Rn-220 to undergo radioactive decay into Pb-212 isotope within the one or more Rn-220 targets. The liquid dissolves the Pb-212 isotope produced by radioactive decay of Rn-220 within the one or more Rn-220 targets. The method further includes directing the liquid containing the Pb-212 isotope from the one or more Rn-220 targets to a Pb-212 collection container, and separating the Pb-212 isotope from the liquid.

Abstract: Techniques for modifying training data for video response quality optimization are provided. In one technique, training data is identified that is generated based on video presentation data that indicates multiple video items were presented to multiple entities. The training data comprises multiple training instances, each indicating a presentation of at least a portion of a video item to an entity. For each training instance in a subset of the training instances, a quality metric of the presentation of the video item indicated in said each training instance is computed and that training instance is modified based on the quality metric. After modifying one or more of the training instances, the model is trained using one or more machine learning techniques. In response to a content request, the model is used to determine whether to transmit a particular video item over a network to a computing device of a particular entity.
