    Abstract: A system for facilitating ray trace operations with shared traversal performs a pre-test operation that includes testing one or more volumes against an acceleration structure associated with a virtual environment to identify a set of candidate nodes of the acceleration structure. The virtual environment comprises one or more virtual objects defined by one or more object components. The system also performs a ray trace operation based upon the set of candidate nodes of the acceleration structure.

    Abstract: A data processing system implements obtaining device information and performance requirements information for a resource-constrained computing device; analyzing the device information and the performance requirements information to determine an amount to compress one or more machine learning models to permit the resource-constrained computing device to operate the one or more machine learning models on the resource-constrained computing device, the one or more machine learning models including a stroke classification model for classifying digital ink stroke information as handwriting or a drawing; compressing the one or more machine learning models to permit the one or more machine learning models to operate on the resource-constrained computing device to generate one or more compressed machine learning models; and deploying the one or more compressed machine learning models to the resource-constrained computing device to process ink stroke information captured by a user interface of the resource-constrained computing device.

    Abstract: Electrode controlled hybridization is used to change local pH and selectively assemble oligonucleotide complexes on the surface of a microelectrode array. The oligonucleotide complexes have sticky ends that provide locations for subsequent oligonucleotide complexes to hybridize. The order in which specific oligonucleotide complexes are joined together encodes information. Controlled activation of individual electrodes in the microelectrode array creates negative voltages that reduces a buffer solution and raises the pH in proximity to the electrodes. At higher pH levels double-stranded oligonucleotides de-hybridize. Nicks between oligonucleotide complexes and oligonucleotides anchored to the microelectrode array are closed creating covalent attachments. De-hybridized single-stranded oligonucleotides are removed leaving only the oligonucleotides connected to microelectrode array. Thus, during a given round of synthesis, oligonucleotide complexes are added only to the locations on the microelectrode array where the electrodes are not activated.

    Abstract: In some aspects, a method of using a virtual medical assistant to assist a medical professional, the virtual medical assistant implemented, at least in part, by at least one processor of a host device capable of connecting to at least one network is provided. The method comprises receiving free-form instruction from the medical professional, providing the free-form instruction for processing to assist in identifying from the free-form instruction at least one medical task to be performed, obtaining identification of at least one impediment to performing the at least one medical task, and inferring at least some information needed to overcome the at least one impediment.

    Abstract: The present concepts relate to lossless data compression techniques for reducing the size of a data structure. Certain data in the data structure that can be either recovered from another source or rebuilt from other available information may be removed from the data structure. To further reduce data size, the retained data in the data structure may be packed into a smaller-bit encoding data type. Additionally, to reduce the data size even more, the packed data may be zipped using a lossless data compression algorithm. To regain the original data structure, the process may be reversed. The zipped data may be unzipped using a lossless data decompression algorithm. The packed data may be unpacked into the original bit-sized data encoding. The removed data may be restored by either recovering it from another source or rebuilding it from other available information.

    Abstract: In various examples, there is a method of enabling an attestable update of a firmware layer that provides a unique identity of a computing device. An immutable firmware layer is used to access a unique device secret. The immutable layer is used to derive a hardware device identity (HDI) from the unique device secret. The immutable layer is used to derive a compound device identity (CDI) from a measurement of the firmware layer and the unique device secret. The CDI and HDI are made available to the firmware layer. The firmware layer is used to issue a local certificate to endorse a device identity key, derived from the CDI, the local certificate signed by a key derived from the HDI.
