Abstract:

A method of forming dummy structures in accordance with the golden ratio to reduce dishing and erosion during a chemical mechanical polish. The method includes determining at least one unfilled portion of a die prior to a chemical mechanical planarization and filling the at least one unfilled portion with a plurality of dummy structures, a ratio of the dummy structures to a total area of the unfilled portion being in the range of 36 percent and 39 percent. A die formed in accordance with the method may include a plurality of metal levels and a plurality of regions at each metal level, each region having a plurality of dummy structures formed as golden rectangles.

Abstract:

Systems and methods for ultrasound shear wave elastography (SWE) are described. According to examples, an ultrasound SWE system includes an ultrasound probe (), an actuation assembly () coupled to the probe and configured to apply an external force against a subject for generating a shear wave within a target region, a controller () coupled to the actuation assembly to control the actuation assembly to apply the force responsive to a trigger signal, and ultrasound scanner () configured to generate the trigger signal, and further configured to generate an elastography image based at least in part on echo signals received from the target region.

Abstract:

Methods of preparing improved metal hydride alloy materials are provided. The alloys include a mixture of at least four of vanadium, titanium, nickel, chromium, and iron. The alloy is processed by at least one of thermal and physical treatment to generate a refined microstructure exhibiting improved kinetics when used as electrodes in MH batteries (e.g., higher discharge current). The thermal treatment includes rapid cooling of the alloy at greater than 10K/s. The physical treatment includes mechanical pulverization of the alloy after cooling. The microstructure is a single phase (body centered cubic) with a heterogeneous composition including a plurality of primary regions having a lattice parameter selected from the range of 3.02 Å to 3.22 Å and a plurality of secondary regions having a lattice parameter selected from the range of 3.00 Å to 3.22 Å and at least one physical dimension having a maximum average value less than 1 μm.
