Abstract: Various embodiments that pertain to a loop antenna are described. The loop antenna can be a single loop antenna that switches between a first phase and a second phase. While operating at different phases, the loop antenna can function at the same frequency. The loop antenna can observe a response to the frequency at the first phase and the frequency at the second phase. This can provide a wider range of information over operation in a single phase.

Perovskites comprise AxA?yA?(1?x?y)BX3, and non-perovskites may comprise A?, B and X, where A is a first cation, A? is a second cation, A? is a third cation, B is a fourth cation, X is an anion. In some instances, A, A?, and A? are each independently (NH2)2CH+, CH3NH3+, Cs+, Rb+, or (NH2)2(C?NH2)+, with the proviso that A, A?, and A? are each different. The perovskite may have a first crystal structure in which the anion is corner-sharing, the non-perovskite may have a second crystal structure comprising at least one of an orthorhombic structure, a hexagonal structure, or a perovskite-like structure, and 1?x?y may be greater than about 0.15.

Abstract: A computing entity accesses instances of medical information corresponding to a population of patients and generates a plurality of medical sentences corresponding to the population by, for each patient of the population, generating one medical sentence corresponding to the patient and a timestamp associated with each instance such that the one medical sentence comprises one or more medical codes in a chronological order. The computing entity generates a vector dictionary comprising a plurality of multi-dimensional vectors based on a vector generation model trained using machine learning and the plurality of medical sentences with each multi-dimensional vector corresponding to a medical code. The computing entity generates a digital representation of a first patient of the population using an anagram model and the vector dictionary, determines a health state of the first patient based on the digital representation, and provides an output indicating the health state of the first patient.

Abstract: A rocket throat insert including an annular body having a radially inner annular wall portion and a radially outer annular portion. The inner wall portion has a contoured radially inner surface defining a nozzle throat. The outer portion includes an annular buttressing structure supporting the inner wall portion and defining one or more insulation gaps arranged annularly around the inner wall portion. The insulation gaps restrict the radial flow of heat through the annular body.

Abstract: An expandable table comprises first and second table surfaces connected by a first hinge at their adjoining short sides. First and second legs are fixed to an underside of the first table surface to support the first table surface. A third leg is fixed to an end of a slidable bar or mechanism wherein the slidable bar or mechanism is installed on an underside of the first table surface, wherein the slidable bar or mechanism is configured to be slid out from under the first table surface wherein the third leg provides support for the second table surface when the second table surface is unfolded and wherein the slidable bar or mechanism is configured to be slid under the first table surface wherein the third leg rests adjacent to the first leg when the second table surface is folded to lie on top of the first table surface.

Abstract: A material deposition system for additive manufacturing including an extruder that defines a first input passage for supplying a first material, a second input passage for supplying a second material, a chamber for combining the first and second materials to form a combined deposition material, and an extrusion port for extruding the combined deposition material. The system further includes an adjustable sleeve that is movable between a first position and a second position to vary the interaction between the first material and the second material in the chamber. For example, the adjustable sleeve may be configured to separate the first and second materials in the chamber, and can vary the point at which the materials interface with each other prior to deposition based on the sleeve position. Such a system may enable a varying degree of infiltration, encapsulation, or other interaction between the first and second materials prior to deposition.

Abstract: A material deposition system for additive manufacturing including an extruder and a measuring device for measuring the viscosity and/or other rheological properties of a build material contained within the extruder. The measuring device may provide feedback to a controller for controlling one or more parameters depending on the measured viscosity and/or other rheological properties of the build material within the extruder.

The mixing device may be operatively coupled to the measuring device for simultaneously measuring the viscosity and/or other rheological properties of the materials during mixing. The controller may be configured to independently control one or more parameters associated with the materials depending on the viscosity and/or other rheological properties measured by the measuring device.
