Abstract: Methods, computer program products, and systems are presented. The methods include, for instance: obtaining a request for a predicted ensemble score in real-time. A subset of base model instances is formed by use of a preconfigured priority policy. A fitness score of the formed subset, quantifying the accuracy of the subset, is calculated as a sum of weights respective to the base model instances in the subset. A number of base models represented in the subset is less than or equal to a number of all based models.

Abstract: Provided is a linker element and a method of using the linker element to construct a sequencing library, wherein the linker element consists of a linker A and a linker B, the linker A is obtained through the complementary pairing of a long nucleic acid strand and a short nucleic acid strand, the 5? end of the long strand has a phosphoric acid modification, and the 3? end of the short strand has an enclosed modification, with enzyme sites in the short strand; and the linker B is a nucleic acid single strand, and the 3? end thereof can be in a complementary pairing with the 5? end of the long strand of the linker A.

Abstract: Provided are techniques for supporting a join operation against multiple NoSQL databases. A search request with a field and a value for the field is received, wherein the search request is to be issued against a plurality of database divisions formed from NoSQL databases. A simple database search is performed against a structured index to generate a first result set. An extended database search is performed against a linear database division index to generate a second result set by: identifying a relationship for the field that identifies related fields and identifying documents for the field and the related fields using a linear database division index. The first result set and the second result set are merged to form a merged result set of documents. The documents from the merged result set are displayed in response to the search request.

Abstract: It is determined an ADV is inevitable to collide with at least one of the objects surrounding the ADV based on the relative positions and speeds between the ADV and the objects in view of the physical dimensions of the ADV. An object may be another vehicle, a pedestrian, a bicycle, a static obstacle. For each of the objects, a collision cost between the ADV and the object is calculated using a set of one or more cost functions or cost algorithms. A collision cost represents an amount of potential damage if the collision is to occur. One of the objects is selected whose collision cost is the least amongst the objects. A path or trajectory is planned for the ADV leading or towards to the selected object to minimize the potential damage when the ADV potentially collide with the selected object compared to the remaining objects.
