Abstract: Disclosed are systems and methods of accessing content items stored at a content management system by a mobile device, when the mobile device is not communicatively coupled to the content management system. The content management system can receive an indication to mark a content item (e.g., folder and the content items associated with the folder) as available to a mobile device when the mobile device is offline. The content management system can mark the content item, and any content items associated with the content item, for offline access by the mobile device and determine a synchronization schedule for the content item(s). The content management system can then initially send to the mobile device, the marked content item(s) in accordance with the synchronization schedule. While offline, the mobile device can make changes to the marked content items. The changes can be synchronized between the mobile device and content management system when the mobile device is online.

Abstract: A method for using distributed representations of data items within a first set of data documents clustered in a first two-dimensional metric space to generate a cluster of distributed representations in a second two-dimensional metric space includes clustering in a first two-dimensional metric space, by a reference map generator, a set of data documents, generating a semantic map. A parser generates an enumeration of data items occurring in the set of data documents. A representation generator generates a distributed representation using occurrence information about each data item. A sparsifying module receives an identification of a maximum level of sparsity and reduces a total number of set bits within the distributed representation. The reference map generator clusters, in a second two-dimensional metric space, a set of SDRs retrieved from the SDR database and selected according to a second at least one criterion, generating a second semantic map.

Abstract: A word completion system based on a partial but exact template that entails a finite number of matches. A primary component is a close ended template made up of cues representing one or more characters, constrained by the exact number of characters in the desired word. It can be edited with pinpoint accuracy to regenerate a new result set in real time to reflect the change. The exact number of characters in the template can be indicated by a discrete signal with a designated gesture or keying in a number. The system is substantially interactive without requiring command line input or a scripting language. A delimiter or a designated signal is used to select an entry from the result set to complete the target word. The proposed method is inherently deterministic and extensible to different writing systems, and adaptable and portable to a wide range of hardware platforms.

Abstract: Systems, methods and computer-readable media are provided for facilitating patient health care by providing discovery, validation, and quality assurance of nomenclatural linkages between pairs of terms or combinations of terms in databases extant on multiple different health information systems that do not share a set of unified codesets, nomenclatures, or ontologies, or that may in part rely upon unstructured free-text narrative content instead of codes or standardized tags. Embodiments discover semantic structures existing naturally in documents and records, including relationships of synonymy and polysemy between terms arising from disparate processes, and maintained by different information systems. In some embodiments, this process is facilitated by applying Latent Semantic Analysis in concert with decision-tree induction and similarity metrics.

Abstract: A computer-based real-world evidence (CRWE) solution that can handle disparities in real-world data (RWD) that might otherwise not be combinable or that might originate from disparate or heterogeneous sources. The CRWE solution is designed such that it can build up RWD data from the ground up (for example, from the atomic level) into a canonical relational database by converting or linking the raw RWD data to its canonical versions such that reliable canonical answers can be mined from large datasets and consistently provided in response to queries to the solution for an answer. The CRWE solution is designed to gather and analyze large amounts of RWD data from heterogeneous, multi-national, and unverifiable data sources, and provide canonical results that are constituently reliable and can expose, for example, clinically-significant correlations between medical products or treatments and outcomes.

Abstract: In connection with processing asynchronous streams of aircraft telemetry data, data processing logic is developed to run on multiple aircraft, even if the aircraft use different avionics equipment. An electronic data inventory system tracks data available on a set of aircraft. A set of “global” data elements applicable to aircraft in a fleet is defined and tracked in the electronic inventory system, along with the relationship to the underlying native data elements and specific aircraft. The global units are derived as appropriate, for each specific aircraft's avionics and/or sensor environment. An interface enables definition of data processing logic that is integrated with the electronic inventory system and ensures the general validity of the defined logic. The data processing logic may be deployed to one or more aircraft in a function integrated with the electronic inventory system, to ensure the validity of the data processing logic for each aircraft specified as a deployment target.

Abstract: The present disclosure provides a method of reading data maintained in a tree data structure, such as B+ tree, using near data processing (NDP) in a cloud native database. According to embodiments, a desired LSN will be used in NDP page reads on the master computing node (e.g. master SQL node). When the master computing node (e.g. master SQL node) reads the regular page, the maximum desired LSN (e.g. the latest page version number) for that regular page will be used. Embodiments use features of the desired LSN and page locking, wherein correct versions of pages can be obtained by using the desired LSN associated with a page, in combination with page locking, and can enable the reading of a consistent tree structure and achieve good read/write concurrency.
