Abstract: Rehabilitation or ambulation assistance can be provided to a user by sensing at least one first pressure beneath the user's right foot, sensing at least one second pressure beneath the user's left foot, and predicting the user's gait based on the sensed at least one first pressure and the sensed at least one second pressure. A plurality of motors are energized at a plurality of times that are synchronized with phases of the user's gait so that the plurality of motors pull on respective cables at respective times in a coordinated sequence. Each of the cables has a first end affixed to a pelvic belt or harness that is shaped and dimensioned to fit securely on the user's pelvis, and the timing of the energizing is based on the gait predictions.

Abstract: A copper concentrate such as chalcopyrite is contacted with an aqueous solution includes acids and a reducing agent, such as vanadium (II) ions, chromium (II) ions, or tungstozincic acid (H6ZnW12O40). The aqueous solution reduces the copper in the copper concentrate, which can then dissolve into the solution for recovery therefrom, or precipitate out of solution as copper compounds or elemental copper for recovery in as a solid phase product. The solid phase product can then be isolated, dissolved, and further electrowinned to recover a copper product from the copper concentrate. Oxidized reducing agent can be recovered in an electrochemical device with ferrous iron reactants. Hydrometallurgical routes to convert copper concentrates to copper are potentially less expensive and less polluting than current pyrometallurgical processing and an advantageous response to environmental and economic pressures for increased copper production.

Abstract: Techniques measuring post contrast phase include collecting 3D medical imagery of a subject after injection with a contrast agent. A first set of slices is obtained in which each includes a first anatomical feature selected from a portal vein, aorta, inferior vena cava, liver, spleen or renal cortex. A second set of slices is obtained in which each includes a different second anatomical feature. A first image region is obtained from the first set and a different second image region from the second set. A trained convolutional neural network is configured to input the first image region to a first plurality of convolutional hidden layers and the second image region to a second plurality of convolutional hidden layers and output from both to a fully connected hidden layer that outputs a post contrast phase. Output data is presented based on the post contrast phase.
