Composite travel disruption monitoring and mitigation
Systems and methods for composite travel disruption monitoring and mitigation in the travel industry using fragmented source data. Reservation records associated with a user profile are accessed in a reservation database. The reservation records are filtered to create a filter sub-set of reservation records that each have a disruption element storing data that indicates a net difference between a base state of a segment when ticketed and an actual state of the segment when the segment terminates. A disruption metric is determined for each segment quantifying a relative impact of disruption events on the segment using data stored in a corresponding disruption element. A composite disruption metric is determined based on the disruption metrics quantifying a cumulative impact of disruption events on a user associated with the user profile. At least one mitigation option is effectuated based on a comparison between the composite disruption metric and a defined threshold. |

For fluorescent nanoparticles having a zeta potential of −10 mV to −60 mV at pH 7.0 or a zeta potential of 0 mV to −10 mV in a buffer of pH 6.0 to 8.0, an appropriate electrical repulsive force can be generated between biomolecules that are generally negatively charged and the fluorescent nanoparticles.

Further, since an appropriate electrical repulsive force is also generated between the fluorescent nanoparticles themselves, aggregation of the fluorescent nanoparticles can be inhibited and the dispersibility in a staining solution can thereby be maintained. |
