  • Publication number: 20250156792
    Abstract: A system determines an amount of time available for responding to a request regarding eligibility for a client account for a modification based on a confidence grade for the client. The system transmits a first query and a second query. The system uses trained machine learning model(s) to determine respective estimated receipt times of first and second datasets responsive to the first and second queries, and to determine respective importance levels of the first and second datasets to determining the confidence grade. The system generates a preliminary confidence grade based on the first dataset, and delays generation of the confidence grade until the second dataset is received based on the estimated receipt times and importance levels. The system updates the preliminary confidence grade using the second dataset to generate the confidence grade, determines the eligibility determination, and updates the training of the machine learning models.

  • Patent number: 12254288
    Abstract: Data selection systems and techniques are described. For instance, a system receives a data set with a plurality of data elements. The system generates a plurality of random values. The system generates a ranking of the plurality of random values. The system selects a subset of the plurality of data elements based on a comparison between the ranking and a predetermined threshold. The predetermined threshold is based on a predetermined proportion of the plurality of data elements to be included in the subset. The system outputs a randomization scheme that includes the ranking and the predetermined proportion, wherein a second selection of a second subset of the plurality of data elements is based on the randomization scheme. The system output an indication of the subset and the second subset.

  • Publication number: 20250065336
    Abstract: An apparatus includes a housing and a sample preparation module disposed within the housing. The sample preparation module has a base including a wall defining a sample reservoir. The apparatus includes a flexible heater having a first end and a second end. The first end of the flexible heater is coupled to a connector to be in electrical communication with a power source. A carrier is coupled to and supports the flexible heater such that the second end of the flexible heater is disposed within the sample reservoir spaced apart from the wall. The apparatus can also include an input retention lid that can be disposed partially within the sample reservoir and includes a retention screen to prevent solid reagents within the sample reservoir from migrating upward.

  • Publication number: 20210319385
    Abstract: In response to receipt of a request for an assessment of a user at a system and from a client terminal, the system identifies a duration of time available for responding to the request and starts a timer. The system transmits requests for information about the user to data sources. The system can and receive some responsive datasets back from the data sources, and can determine which responsive datasets are optimal to wait for and which are not based on how closely the timer is approaching the duration of time available for responding to the request. The system generates the assessment of the user based on the datasets that the system received before the timer reached a threshold time that is based on the duration of time available for responding to the request, and sends the assessment of the user to the client terminal.

  • Publication number: 20090291939
    Abstract: Certain atypical antipsychotic medications (particularly clozapine) or combinations of medications are useful to treat alcohol or other substance abuse, particularly in the general (non-schizophrenic) population. Generally stated, one aspect of the invention features a method of treating a patient suffering from alcohol or other substance abuse by administering to the patient medication effective to rectify an abuse-associated dysfunction in the DA-mediated brain reward circuit. A second aspect of the invention features administering medication that strongly antagonizes ?2 andrenergic receptors and weakly antagonizes dopamine D2 receptors. Preferably, the ratio of ?2 receptor blockade to D2o receptor blockade is similar to that of clozapine. The medication may be a single compound (such as clozapine or risperidone), or it may include two or more compounds which together achieve the specified function.
