Abstract: The present disclosure generally relates to semiconductor processing in which an alignment mark is formed. An example is method of semiconductor processing. First and second recesses are formed in a semiconductor substrate. A conformal dielectric layer is formed in the first and second recesses and over the semiconductor substrate. A fill material is formed over the conformal dielectric layer in the first recess and over the conformal dielectric layer in the second recess. The fill material fills at least the first recess over the conformal dielectric layer. The fill material in the first and second recesses is recessed to below a top surface of the conformal dielectric layer. The recessed fill material in the first and second recesses is etched. Exposed portions of the conformal dielectric layer are etched. The second recess including the conformal dielectric layer and the recessed fill material disposed therein forms an alignment mark.

Abstract: A method for performing vector-matrix multiplication may include converting a digital input vector comprising a plurality of binary-encoded values into a plurality of analog signals using a plurality of one-bit digital to analog converters (DACs); sequentially performing, using an analog vector matrix multiplier and based on bit-order, vector-matrix multiplication operations using a weighting matrix for the plurality of analog signals to generate analog outputs of the analog vector matrix multiplier; sequentially performing an analog-to-digital (ADC) operation on the analog outputs of the analog vector matrix multiplier to generate binary partial output vectors; and combining the binary partial output vectors to generate a result of the vector-matrix multiplication.

Abstract: A storage system includes a panel secured to a support surface and a storage container removably supported on the panel. The panel includes a plurality of cleats. The storage container includes a first container portion, a second container portion, and a support feature engageable with the cleats. The second container portion and the first container portion are pivotably movable between a closed position and an open position. The support feature includes a first partial mounting portion and a second partial mounting portion. The second partial mounting portion is movable between a stowed position and an extended position. The first partial mounting portion and the second partial mounting portion cooperate to provide a mounting interface to engage the cleats while the second partial mounting portion is in the extended position.

Abstract: Provided herein are methods of treating a COVID-19 infection in a subject, comprising administering to the subject an effective amount of a composition that reduces the superantigen character of SARS-CoV-2 Spike protein. In some embodiments, the compositions are mimetic peptides of the superantigen region. In some embodiments, the compositions are humanized antibodies, such as humanized mAb 6D3, that bind to the superantigen region.

Abstract: A casement operator for opening and closing a window includes a housing, a cover and a crank assembly. The cover is moveable between a closed position and an open position. The crank assembly is pivotable and includes a crank handle and a gear mounted to the crank handle. The crank handle is pivotable between a retracted position and an extended position. The crank handle is enclosed within a storage cavity in a storage position. The crank handle includes a bore proximate a base end and the gear has a first detent and a second detent. A biasing member is mounted within the bore and a securing plug is mounted at least partially within the bore. The biasing member biases the securing plug toward the gear such that the securing plug is located in the first detent in the retracted position and in the second detent in the extended position.

Abstract: A non-handed actuator for window locks of the type in which a lock control member is moved by the actuator to control the locking of a window sash to a window frame. The actuator includes a housing base that is securable to the window frame and a handle is secured to the base for pivoting about a first axis and a drive link is secured for pivoting with the handle. A connecting link is securable at its distal end to the lock control member of a window lock. The connecting link is pivotally secured at its proximal end to the drive link. The connecting link is provided as a selectable pair which are generally a mirror image of each other, one provided and dimensioned for right-hand operation of the lock control member and the other provided for left-hand operation of a lock control. The unneeded connecting link is discarded. The connecting links are generally L-shaped so that the proximal end of the connecting link is received in a cavity provided in the base.

Abstract: A bearing assembly for use with a window operator has a housing with an operator slot and a bore through which is threaded an adjustable bearing. The bearing contains a smooth end with two walls of differing diameter that form shoulders. The shoulders fit substantially against an inner and outer surface of the slot to rotatably position and secure an operator arm therein.

Abstract: The invention provides a biodegradable thermoplastic composition made of soy protein, a plasticizing agent, a foaming agent, and water, that can be molded into biodegradable articles that have a foamed structure and are water-resistant with a high level of physical strength and/or thermal insulating properties.
