Abstract: A method for analyzing an aggregation-crystallization process of a calcium phosphate prenucleation cluster. A small amount of the aggregation-induced emission organic molecule and the rare earth ion are doped into the calcium phosphate prenucleation cluster, and the two are used as a fluorescent dual probe to participate in the subsequent evolution process. The organic molecule binds to the calcium ion in the cluster. As the local molecular density of the aggregated organic molecules of the PNCs increases, the limitation of intramolecular motion is further strengthened, the energy loss of the excited state is reduced, resulting in opening of the electron transition channel and showing a phenomenon of enhanced fluorescence signal.

Abstract: Generating a synthetic dataset from road vehicle positioning data. The method involves iteratively selecting a seed record and determining a set of candidate partner records based on matching bigrams between the selected seed record and potential partner records. The method further includes determining subsequences for the candidate partner records and selected seed record based on locations of the matching bigrams. A candidate partner record is selected based on whether a length difference, in terms of time, distance, or number of road events, between the subsequences is less than a defined threshold. The subsequence of the selected seed record is replaced with the subsequence of the selected candidate partner record to produce a mutated seed record. The mutated seed records to produce a synthetic dataset.
