Toward the center of the ring-shaped magnet, the attachment assembly has an accommodating recess. The support assembly includes a handle that is movable on a hinge in and out of the accommodating recess. The joint permits the handle to rotate about a first axis and a second axis not parallel to the first axis.

Abstract: Mechanisms are provided for implementing a framework to learn multiple drug-adverse drug reaction associations. The mechanisms receive and analyze patient electronic medical record data and adverse drug reaction data to identify co-occurrences of references to drugs with references to adverse drug reactions (ADRs) to thereby generate candidate rules specifying multiple drug-ADR relationships. The mechanisms filter the candidate rules to remove a subset of one or more rules having confounder drugs specified in the subset of one or more candidate rules, and thereby generate a filtered set of candidate rules. The mechanisms further generate a causal model based on the filtered set of candidate rules. The causal model comprises, for each ADR in a set of ADRs, a corresponding set of one or more rules, each rule specifying a combination of drugs having a causal relationship with the ADR.

The 3D geological model can be used in conjunction with a fluid-flow simulator to generate a first 3D resistivity distribution. A second 3D resistivity distribution can be generated based on electromagnetic survey data of the formation. The 3D geological model can be updated based on differences between the first and second 3D resistivity distributions. The simulation and subsequent update to the 3D geological model can be repeated until differences between the first and second 3D resistivity distributions satisfy a stopping criterion. Data characterizing properties of the formation can be extracted from the resulting 3D geological model.
