Abstract: A computing system cryptographically generates an intermediate message authentication code as a function of the message and a cryptographic key assigned to a first party. The computing system also generates a first instance of an aggregate message authentication code corresponding to the message by combining the intermediate message authentication code with one or more other intermediate message authentication codes of one or more second parties. Each code of the one or more other intermediate message authentication codes is cryptographically generated as a function of the message and individual cryptographic key assigned to each of the one or more second parties.

Abstract: A computing system determines a maximum field size for a field containing values of quantized versions of a weight matrix, an input data matrix, and a bias matrix and determines a weight upper bound of scaling factors for the weight matrix based on values of the weight matrix, an input data upper bound of scaling factors for the input data matrix based on values of the input data matrix, and a bias upper bound of scaling factors for the bias matrix based on values of the bias matrix. The computing system also sets a weight scaling factor of the weight matrix, an input data scaling factor of the input data matrix, and a bias scaling factor for the bias matrix in two different cases: when the sum is less than or equal to the bias upper bound and when the sum is greater than the bias upper bound.

Abstract: A data storage system for use in a high radiation environment has a radiation-hardened storage controller that measures a current draw of a storage drive in a storage array. The storage drive is not radiation-hardened. Based on a characteristic of the current draw, a latch up is detected the storage drive. Based on the detected latch up, power is removed from all or part of the storage drive. After a cooling period has elapsed, the power is reapplied to the storage drive.

Abstract: Methods for analysis of the magnetic grain using a software program effectively and accurately by improving the magnetic grain boundary contrast from an image prior to analyzing the grain size with an imaging analysis program. A method for automated grain size analysis includes obtaining a SEM electronic image of a magnetic material composed of a plurality of grains and modifying the image by smoothing the image, removing high spatial and low spatial frequencies from the image, improving contrast of the image, pixelating the image, processing the image to a binary image, and clearing outer edges of the binary image to remove at least incomplete grains to generate grain size data from the image.

Abstract: A heat-assisted magnetic recording head comprises a near-field transducer (NFT). The NFT comprises a near-field emitter configured to heat a surface of a magnetic disk, and a hybrid plasmonic disk. The hybrid plasmonic disk comprises a plasmonic region and a thermal region. The plasmonic region comprises a first material or alloy that is a plasmonic material or alloy. The thermal region comprises a second material or alloy that is different than the first material or alloy.

Abstract: A secure cartridge-based storage system includes a set of read/write control electronics on a shared controller adapted to removably couple with each of a plurality of storage cartridges. Data blocks within primary non-volatile memory of the cartridge-based storage system collectively comprise a main store with information-theoretic security. The shared controller incorporates various controls for providing selective data access to individual data magazines and/or cartridges as well as for partitioning user data and writing the partitioned data according to an information-theoretic security scheme and reading the partitioned data and reconstructing the user data from the partitioned data.

Abstract: Evolving function secret sharing is performed on a given function by multiple share parties, A dealer selects a random vector for each share party corresponding to an arrival order. The dealer generates an array of function shares for each share party of the set, each array including a function share based on the random vector corresponding to the share party and one or more function shares cryptographically generated based on the random vector corresponding to each previously-arrived share party. The dealer distributes an array of the function shares to each share party, wherein a first function share result resulting from a computation of a first function share on given input data and at least a second function share result resulting from a computation of a second function share on the given input data are combinable to yield a result of the given function executed on the given input data.

Abstract: An apparatus includes a data storage disc having a read/write surface, and an arm extending along an arm axis and having a head end that supports a head that is configured to interact with the read/write surface. The apparatus also includes a rail extending along a rail axis that is normal to the arm axis, and a carriage coupled to the arm and movably coupled to the rail. The apparatus further includes a latch mechanism configured to releasably hold the carriage to the rail at a fixed position.

Abstract: A data storage system may store a first data block having a first data configuration generated by a host in a non-volatile memory that is connected to a data module. A data strategy may be generated with the data module in response to the storage of data with the data strategy consisting of at least one trigger associated with identifying the first data block as hot. The first data block can be replicated to a different memory location with a second data configuration as directed by the data strategy with the first data configuration being different than the second data configuration.

Abstract: The slow speed of conventional selective electroplating and L-PED (and further requirement of a series of masks in the case of selective electroplating) necessary to generate a metallic three-dimensional object makes conventional selective electroplating and L-PED not viable for mass manufacturing metallic three-dimensional objects. The presently disclosed technology generally utilizes electroplating and L-PED technologies with a screen electroplating process. The screen electroplating process disclosed herein is capable of achieving a faster throughput and a lower workpiece temperature than traditional 3D printing processes can provide, particularly traditional metal 3D printing processes. As a result, the presently disclosed screen electroplating process is able to achieve much faster results in printing a complex three-dimensional metallic structure using electroplating.
