US11501545B2	Smart microscope system for radiation biodosimetry Automation of microscopic pathological diagnosis relies on digital image quality, which, in turn, affects the rates of false positive and negative cellular objects designated as abnormalities. Cytogenetic biodosimetry is a genotoxic assay that detects dicentric chromosomes (DCs) arising from exposure to ionizing radiation. The frequency of DCs is related to radiation dose received, so the inferred radiation dose depends on the accuracy of DC detection. To improve this accuracy, image segmentation methods are used to rank high quality cytogenetic images and eliminate suboptimal metaphase cell data in a sample based on novel quality measures. When sufficient numbers of high quality images are found, the microscope system is directed to terminate metaphase image collection for a sample. The International Atomic Energy Agency recommends at least 500 images be used to estimate radiation dose, however often many more images are collected in order to select the metaphase cells with good morphology for analysis. Improvements in DC recognition increase the accuracy of dose estimates, by reducing false positive (FP) DC detection. A set of chromosome morphology segmentation methods selectively filtered out false DCs, arising primarily from extended prometaphase chromosomes, sister chromatid separation and chromosome fragmentation. This reduced FPs by 55% and was highly specific to the abnormal structures (≥97.7%). Additional procedures were then developed to fully automate image review, resulting in 6 image-level filters that, when combined, selectively remove images with consistently unparsable or incorrectly segmented chromosome morphologies. Overall, these filters can eliminate half of the FPs detected by manual image review. Optimal image selection and FP DCs are minimized by combining multiple feature based segmentation filters and a novel image sorting procedure based on the known distribution of chromosome lengths. Consequently, the average dose estimation error was reduced from 0.4 Gy to <0.2 Gy with minimal manual review required. Automated image selection with these filters reduces the number of images that are required to capture metaphase cells, thus decreasing the number of images and time required for each sample. A microscope system integrates image selection procedures controls with an automated digitally controlled microscope then determines at what point a sufficient number of metaphase cell images have been acquired to accurately determine radiation dose, which then terminates data collection by the microscope. These image filtering approaches constitute a reliable and scalable solution that results in more accurate and rapid radiation dose estimates.

The acts can include obtaining a sequence of stops and service time windows for the stops. The acts also can include generating a sequence of driver states that satisfies the sequence of the stops. The acts further can include determining, for each pair of respective sequential driver states from the sequence of driver states, whether to generate a respective recommendation to add a respective additional driver state within the respective sequential driver states in order to satisfy a set of rules. The acts additionally can include updating the sequence of driver states based on the respective recommendations, such that the sequence of driver states is feasible in view of the service time windows and the set of rules. The acts further can include outputting the sequence of driver states. Other embodiments are described.
US11501240B2	Systems and methods for process design including inheritance Systems and methods for analyzing information are provided in which a plurality of attribute records are stored. Each respective record in at least a subset of the plurality of records comprises a corresponding unique identifier, a superior/inferior attribute reference, and a heritage indicator. A superior/inferior attribute reference of a first record in the plurality of records references a unique identifier of a second record that is different than the first record, thereby indicating that the first record is a nested attribute record of the second record. Moreover, a heritage indicator of the first record references: the corresponding unique identifier of a third record, thereby indicating that the third record is an ancestor record of the first record, or a unique identifier of a first attribute class record, thereby identifying an attribute class record, in a plurality of attribute class records, to which the first record belongs.
