Semantically-enhanced EMR data derived from the ontology processing engine is incorporated into both real-time ‘track and trigger” rule engines and machine learning training algorithms using aggregated data. The resulting rule engines and machine-learnt models provide enhanced diagnostic and prognostic information respectively, to assist in clinical dual modes of reasoning (analytical rules and models based on experiential data) to assist in decisions associated with the specific disease in acute critical care settings. |

Hence, multiple memory cells are concurrently accessed. In some aspects, the memory cells are accessed using a self-referenced read (SRR), which improves read margin. Concurrently accessing more than one memory cell in a cross-point memory array improves bandwidth. Moreover, such concurrent accessing allows the memory system to be constructed with fewer, but larger cross-point arrays, which increases array efficiency. Moreover, concurrent access as disclosed herein is compatible with memory cells such as MRAM which require bipolar operation. |

Machine learning systems, methods, components, and software for recommending and ordering independent medical examinations
Millions of bodily injury insurance claims are filed yearly to help people who've suffered accidents from work, slip-and-falls, and auto collisions. In processing these claims, insurance companies, TPAs, and law firms routinely hire experts, such as physicians, to conduct independent medical evaluations (IMEs) to assist claims adjusters and attorneys in analyzing the eligibility of claimants for indemnity and medical benefit payments. IMEs typically cost thousands of dollars each. Yet, many are ordered too early, wasting money that could otherwise be used to reduce insurance premiums. To reduce this waste, the inventors devised, among other things, one or more exemplary systems which not only predict the outcomes of IMEs based on claimant medical records and/or or activity data before ordering them, but also presents selected claims and predictions within a graphical user interface that facilitates ordering the IMEs from a list of available physicians. |

System, method, and computer program for obtaining a unified named entity recognition model with the collective predictive capabilities of teacher models with different tag sets using marginal distillation
The present disclosure sets forth a marginal distillation approach to obtaining a unified name-entity recognition (NER) student model from a plurality of pre-trained teacher NER models with different tag sets.

A distillation loss is computed between the student and each of the teacher models. If teacher's predictions are less fine-grained than the student's with respect to a node in the tag hierarchy, the student's more fine-grained predictions for the node are marginalized in computing the distillation loss. The overall loss is minimized, resulting in the student model acquiring the collective predictive capabilities of the teacher models. |

System and method for finite elements-based design optimization with quantum annealing
A method and system perform quantum-assisted finite elements-based, design optimization of an object to minimize a shape-specific quantity by manipulating the shape of the object using a processing unit, for example, a Quantum Processing Unit (QPU). As a result, a shape-specific quantity, such as an approximation of sound pressure at a specific position around an object, can be minimized by manipulating the object shape using the QPU. |

Generating a debris model for a structure
A computer generates a computer model based on the output data of a finite element analysis (FEA) performed on a structure that has experienced a break up event. The output data is processed to generate a debris model. The debris model comprises data defining the structure, as well as any fragments or pieces of debris caused by forces exerted on the structure during the break up event. The debris model can then be utilized as input data to generate other computer models. |

Simulating a cable driven system representative of a robot
A cable driving a large system such as cable driven machines, cable cars or tendons in a human or robot is typically modeled as a large number of small segments that are connected via joints. The two main difficulties with this model are satisfying the inextensibility constraint and handling the typically large mass ratio between the segments and the objects they connect. This disclosure introduces an effective approach to solving these problems. The introduced approach simulates the effect of a cable using a new type of distance constraint called ‘cable joint’ that changes both its attachment points and its rest length dynamically. The introduced approach models a cable connecting a series of objects, e.g., components of a robot, as a sequence of cable joints, reducing the complexity of the simulation from the order of the number of segments in the cable to the number of connected objects. |

Method and system for brace designing
Method and system for brace designing. The method comprises the following steps: S1) fixing a subject requiring a brace; S2) acquiring skeletal image information of the subject; S3) determining an adjustment solution for implementing an adjustment with respect to the subject and a target state that is to be achieved ultimately; S4) adjusting the subject to alter the skeletal structure of the subject; S5) acquiring adjusted skeletal image information of the subject; S6) determining whether the skeleton of the subject has been adjusted to the target state; if yes, then terminating adjustment and entering step S7; if not, then returning to step S4; S7) acquiring the body surface three-dimensional shape of the subject having achieved the target state and recording information of the force applied by an adjusting head to the subject for use in manufacturing a corresponding brace; thus allowing the highly efficient designing of a brace. |
