Abstract: Fully automated computer-implemented deep learning techniques of contrast-enhanced cardiac MRI segmentation are provided. The techniques may include providing cardiac MRI data to a first computer-implemented deep learning network trained in order to identify a left ventricle region of interest to generate left ventricle region-of-interest-identified cardiac MRI data. The techniques may also include providing the left ventricle region-of-interest-identified cardiac MRI data to a second computer-implemented deep learning network trained in order to identify myocardium to generate myocardium-identified cardiac MRI data. The techniques may further include providing the myocardium-identified cardiac MRI data to at least one third computer-implemented deep learning network trained to conform data to geometrical anatomical constraints in order to generate anatomical-conforming myocardium-identified cardiac MRI data.

Abstract: Computer-implemented neural network techniques for predicting patient-specific arrhythmic sudden cardiac death survival are presented. The techniques can include obtaining cardiac image data for a patient; obtaining cardiac covariate data for the patient; providing the cardiac image data to a first subnetwork; providing the cardiac covariate data to a second subnetwork; combining an output from the first subnetwork with an output from the second subnetwork to produce survival probability data; and outputting patient-specific arrhythmic sudden cardiac death survival prediction data based on the survival probability data.

Abstract: A method includes receiving a plurality of inputs including domain parameters and initial weights. The method also includes providing the plurality of inputs to an optimization model. The method also includes performing, using a first layer of the optimization model, a training and optimization process based on the plurality of inputs and based on a training objective, The method also includes performing, using a second layer of the optimization model, a differencing operation on an output of the first layer. The method also includes recording, using a third layer of the optimization model, a loss based on the training objective used by the optimization model. The method also includes calculating and storing, using a fourth layer of the optimization model, metrics regarding the training and optimization process. The method also includes outputting, using the optimization model, updated weights.

Abstract: Described herein is a method of setting-up a range-based tracking system utilising a tracking coordinate system that uses a plurality of spaced apart stationary nodes for tracking objects within a tracking environment. The method includes the step of transmitting signals between the stationary nodes to obtain range information between at least a subset of pairs of the nodes and determining coordinates for all of the stationary nodes in a node coordinate system using these range information. The method also includes the step of obtaining spatial information related to at least one of the nodes, the spatial information being indicative of one or more features or locations within the tracking environment and determining the location of all stationary nodes in the tracking coordinate system, wherein some or all of the coordinates of the stationary nodes are used for tracking objects in the tracking system.

Abstract: An aluminum power transmission rail product comprises a profile main component made from molten aluminum onto which a stainless steel cap has been co-cast. Preferably, this main component has a locking feature such as a down-turn on at least one edge of the stainless steel cap. The rail product is preferably cast on a casting unit selected from the group consisting of a horizontal caster, a horizontal DC caster, an MDC caster and a semi-solid casting unit.

Abstract: A method of manufacturing an aluminum power transmission rail product with a metallurgically bonded stainless steel cap comprises providing molten aluminum in a tundish; providing a roll formed stainless steel wear cap; pretreating and preheating the stainless steel cap, then introducing that cap into the tundish; co-casting the aluminum and cap through one or more dies; and tensioning the stainless steel cap at an exit of the casting die and rapidly cooling the same. An aluminum-stainless composite product is also disclosed.

Abstract: A wheel brake for a vehicle including a brake disc unit adapted to brake the rotation of a rotation element, which is adapted to be drivingly connected to the wheel. The brake disc unit includes a first set of discs and a second set of discs arranged in an alternating manner in an axial direction. The discs in the first disc set are adapted to be rotationally rigidly connected to the rotation element. The brake disc unit includes at least one separator element, which is adapted to keep a sufficient distance between two adjacent discs of one of the disc sets for an intermediate disc from the other disc set to rotate at least substantially freely relative to the spaced discs when the brake disc unit is in a deactivated condition.
