  • Patent number: 11194860
    Abstract: Systems and methods are disclosed for question generation to obtain more related medical information based on observed symptoms from a patient. In embodiments, possible diseases associated with the observed symptoms are generated by querying a knowledge graph. In embodiments, candidate symptoms associated with the possible diseases are also identified and are combined with the observed symptoms to obtain combined symptom sets. In embodiments, discriminative scores for the candidate symptom sets are determined and candidate symptoms with top discriminative scores are selected. In embodiments, these selected candidate symptoms may be checked for conflicts with observed symptoms and removed from further consideration if a conflict exists. In embodiments, one or more questions may be generated based on the remaining selected candidate systems to aid in collecting information about the patient. In embodiments, the process may be repeated with the updated observed symptoms.

    Abstract: A method for reconfiguration of a vortex density in a rare earth manganate, to a non-volatile impedance switch having reconfigurable impedance, and to the use thereof as micro-inductance is disclosed. A unique voltage-time profile is applied between a first and a second electrically conductive contact attached to the rare earth manganate, such that the rare earth manganate passes through an ordering temperature in a region of an electric field forming between the two electrically conductive contacts during a cooling process during and after application of the voltage pulse or the voltage ramp, and the vortex density is thus influenced and adjusted locally in the region of the electric field forming between the two electrically conductive contacts.
