  • Patent number: 11201243
    Abstract: The current disclosure describes techniques for forming a gate-all-around device where semiconductor layers are released by etching out the buffer layers that are vertically stacked between semiconductor layers in an alternating manner. The buffer layers stacked at different vertical levels include different material compositions, which bring about different etch rates with respect to an etchant that is used to remove at least partially the buffer layers to release the semiconductor layers.

  • 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.
