Abstract: Knee implants having a convex outer surface formed of a stack of sheets of bacterial cellulose that is between 2-10 mm thick and has been impregnated and crosslinked to form a hydrogel having a concentration of cross-linked bacterial cellulose nanofibers of between 2-20 weight % of the hydrogel, so that the hydrogel has a tensile strength of greater than 5 MPa, a tensile modulus of greater than 8 MPa, and a compression strength of greater than 14 MPa. The implant may have a metallic body and may be generally mushroom-shaped.

Abstract: Conventional high performance computer connections are electron-based systems, which require the memory packages to be as close as mechanically possible to the computation engine. Low power and high bandwidth communication, e.g. photonic, links can drastically change the architecture of high-performance computers by eliminating the bottlenecks in communication. A computer system comprises: a plurality of memory aggregation devices configured to retrieve data from and store data in a plurality of random access memory modules forming a unified contiguous memory address space disaggregated from a processing unit; a plurality of computational devices configured for simultaneously launching a plurality of data signals including memory read and/or write requests for the data to the plurality of memory aggregation devices; and a plurality of communication links coupling each of the plurality of memory aggregation devices to each of the plurality of computational devices for transferring the data therebetween.

Abstract: Artificial cartilage materials for repair and replacement of cartilage (e.g., load-bearing, articular cartilage). The artificial cartilage materials described herein include triple-network hydrogels including a cross-linked fiber network (e.g., a bacterial cellulose nanofiber network) and a double-network hydrogel (e.g., a double-network hydrogel including polfacrylamide-methyl propyl sulfonic acid). The artificial cartilage may be coated onto or formed into an implant (e.g., plug). The artificial cartilage may include a surface macroporosity, e.g., 0.1-300 micrometers diameter. Also described herein are methods of forming and methods of using the triple-network hydrogel artificial cartilage materials.

Abstract: Compact logic evaluation gates are built using null convention logic (NCL) circuits. The inputs to a null convention circuit include a NCL true input and a NCL complement input. The NCL circuit includes a gate coupled to the pair of inputs, where the gate comprises a plurality of transistors. The transistors allow for logical signal capture, provide a pair of cross-coupled inverters for data storage, and include a first and second pull-down device. The first pull-down device causes a first side of the pair of cross-coupled inverters to go to a “0” state when a “1” is applied to the NCL true input, and the second pull-down device causes a second side of the pair of cross-coupled inverters to go to a “0” state when a “1” is applied to the NCL complement input.
