Abstract: A mechanoionic current generator comprising: a working electrode including an activated carbon cloth; and a counter electrode including a raw carbon cloth and a hydrogel; wherein the hydrogel has a plurality of flexible and asymmetrically shaped structures; and the working electrode has a surface immersed in the hydrogel and provided with a plurality of oxygen-containing functional groups. The ionic current generation mechanism of the current generator is naturally compatible with living organisms and living hydrogels, as exemplified by a self-powered drug delivery patch for wound healing. The current generator provides excellent outputs of current and charge transfer which are advantageous for various biomedical applications.

Abstract: Provided herein are apparatus and methods for batch rebalance in distributed data parallel DNN training. An apparatus includes interface circuitry; and processor circuitry coupled with the interface circuitry, wherein the processor circuitry is to: obtain sorted samples of a mini batch via the interface circuitry, wherein the sorted samples are in an ascend or descend order based on a volume of each of the samples; and assign the sorted samples to each of a plurality of local batches one by one in an order from a first local batch to a last local batch of the plurality of local batches and then from the last local batch to the first local batch until all of the sorted samples are assigned. Other embodiments may also be disclosed and claimed.

Abstract: A composite nanofiber aerogel (CNA) is formed from aramid nanofibers (ANFs) combined with polyvinyl alcohol (PVA). These nanoscale constituents of the aerogel form 3D networks with high nodal connectivity and strongly welded connectivity joints between fibrils so that the structure has high stiffness and strength compared to other polymeric aerogels and successive breakage of crosslinks at the connectivity nodes affords energy dissipation while maintaining the overall structural integrity. A specific class of CNA with a specific solid content may be used to form a thin firm with a composite nanofiber framework (CNFF) that is useful in the manufacture of kirigami wearable electronics.

Abstract: Method, systems and apparatuses may provide for technology that identifies first data and second data to be stored in a data storage. Each of the first data and the second data are in a first data format. Some technology may also interleave the first data with the second data. The interleaved first and second data are in a second data format. The second data format is different from the first data format.

Abstract: Systems, apparatuses and methods may provide for technology that identifies an embedding table associated with a neural network. The neural network is associated with a plurality of compute nodes. The technology further identifies a number of entries of the embedding table, and determines whether to process gradients associated with the embedding table as dense gradients or sparse gradients based on the number of entries.

Abstract: Systems, apparatuses and methods may provide for technology that determines a ratio of floating point instructions to memory read instructions and controls a dimension size of a matrix kernel based at least in part on the ratio. In one example, the matrix kernel conducts an operation between a first matrix and a second matrix and the technology reuses elements of the first matrix for multiple vector lines of the second matrix.
