    摘要： 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.

    摘要： A secret sharing scheme with yes and no shares and having a hidden access structure. The secret sharing scheme may include share generation in which yes shares and no shares are generated for, and distributed to, each party in the secret sharing scheme. In turn, upon an attempt to reconstruct the secret, participants in the reconstruction each provide a share, which is unknown to be a yes share or a no share to the other participants. The secret is only reconstructable if the shares used in the reconstruction include yes shares of a minimal authorized subset of the parties. However, prior to secret reconstruction, the access structure remains hidden and the participants in a reconstruction are unaware of the character of the shares provided by other participants in the reconstruction attempt.

    摘要： Failure-domain-specific cryptographic keys for use in control of access to data within failure domains of a storage drive. A unique failure domain-specific cryptographic key may be associated with each of a plurality of failure domains in a storage drive. The failure domains may correspond to any portion of the storage media of a drive that is susceptible to failure while leaving other portions of the storage drive functional. In turn, upon detection of a condition associated with a failure (e.g., an actual or predicted failure) of a failure domain, the associated failure domain-specific cryptographic key may be deleted to preclude further access to data in the failed failure domain. Deletion of the failure domain-specific cryptographic key may be before or after data in the failed failure domain is rebuilt in another portion of a storage drive that is functional.

    摘要： Methods of writing data to a DNA strand by inserting data-encoding oligos or symbols into a DNA backbone. One particular method of synthesizing a DNA strand encoding data includes cleaving a DNA backbone into multiple segments, and pasting a plurality of data-encoding oligo symbols between the multiple segments, with the terminal ends of the segments joining homologous terminal ends of the symbols, resulting in the DNA strand encoding data comprising alternating segments and symbols.
