Abstract: A method for improving an estimation of a property of a quantum state may include (a) using an interface of a digital computer to receive an indication of the property of the quantum state to be estimated; at least one quantum device; and at least one computational platform. The method may include using the at least one quantum device to obtain a plurality of measurement results of the quantum state. The method may include using the at least one computational platform to construct and train a neural network using the plurality of measurement results, wherein the neural network comprises at least one trainable parameter and wherein the neural network is representative of the quantum state. The method may include using the at least one computational platform and the property of the quantum state to train the at least one trainable parameter of the neural network to variationally improve the quantum state.

Abstract: A multifunctional mobile exercise apparatus and method for exercising the upper extremities is disclosed. The apparatus includes a base, an elongate shaft pivotally coupled to the base, a plurality of ground lockable ground wheels supporting the base. The apparatus includes a resistance clip that is selectively positionable along a length of the elongate shaft. A cylindrical sleeve may also be provided for sliding, with or without a resistance band, along the length of the elongate shaft. The mobile exercise apparatus provides single or bilateral hold for one or more resistance bands and the mobile arm. The resistance band and the mobile arm can be held by the injured or non-injured extremity. The elongate shaft and locks up to 8 feet high, and can also be used for the attachment jumbo resistance clips, or for the sliding exercises.

Abstract: A sealable container for preservation of a biological sample is provided. The container includes a cap comprising a proximal open and a lumen and an elongate body that extends from a handle portion to a specimen portion. A closure portion is disposed between the handle portion and the specimen portion, wherein the closure portion is configured to make surface to surface contact with the cap when the specimen portion is fully inserted within the lumen. The closure portion comprises an outer diameter that gradually decreases in a direction from the handle portion to the specimen portion. The specimen portion comprises a scooped portion where a distance between the upper surface and the lower surface is less than distances between the upper surface and the lower surface along remaining portions of the specimen portion, wherein the scooped portion is spaced proximally from a distal tip of the specimen portion.

Abstract: A bio-composite material comprises protein-containing non-wood fibrous biomass comprising at least 6 wt % protein, and a cross-linking agent. The bio-composite material may optionally further contain wood biomass, or non-protein-containing non-wood biomass, and is formable into a bio-composite board to replace wood-based boards for a variety of applications. A bioplastic material comprises a bioadhesive, fibrous biomass and a plastic material, and is formable into a variety of products, such as a cup, using conventional plastic processing techniques. Suitable fibrous biomass may include used coffee grounds and a variety of other biomass. A method of forming a board from a bio-composite material, and a method of manufacturing a bioplastic are also provided.

Abstract: A jack may comprise a contact clip and a housing. The housing may be generally cylindrical and bounded by an imaginary cylinder. The housing may define a substantially cylindrical cavity and a contact aperture. The substantially cylindrical cavity may have an opening at a first end of the housing. The contact aperture may be configured to receive the contact clip. The contact aperture may extends from an outer surface of the housing to the cylindrical cavity. The contact clip may be friction-fitted into the contact aperture and extend into the substantially cylindrical cavity.
