Abstract: Systems and methods are described for configuring a document management system. In various aspects, post data of a user who submitted an online posting to one or more document management systems is collected. The post data includes a node that identifies the user. Metadata is extracted from the post data, in which the metadata includes an identifier for identifying the posting distributed by the one or more document management systems. The identifier is used to collect reaction data from the one or more document management systems, where the reaction data is associated with the user's posting. A mapping is generated from the post data and the reaction data, in which the mapping includes an association of the node with at least one edge, the edge identifying a second user who reacted to the posting. At least one of the document management systems is then configured with the mapping.

Abstract: Embodiments of the disclosure include implementing a ML-enabled cellular disease model for validating an intervention, identifying patient populations that are likely responders to an intervention, and developing a therapeutic structure-activity relationship screen. To generate a cellular disease model, data is combined from human genetic cohorts, from the literature, and from general-purpose cellular or tissue-level genomic data to unravel the set of factors (e.g., genetic, environmental, cellular factors) that give rise to a particular disease. In vitro cells are engineered using the set of factors to generate training data for training machine learning models that are useful for implementing cellular disease models.

Abstract: Additive manufacturing or 3D printing produces considerable quantities of waste ink or resin during the course of additive manufacture. The waste ink is a hazardous substance and must be collected and disposed of accordingly. The present embodiments provide a waste ink collection device that collects the waste ink from the printing process, or from head cleaning and other incidental operations, stores the waste and cures it. The waste ink is thus rendered safe for conventional disposal. A waste ink disposal cartridge collects the waste ink and carries out curing.

In one example, a method may include sealing the crankcase from the vent hose, initiating cranking of the engine, monitoring a series of pressure pulsations during a monitoring window duration via a pressure sensor positioned between a crankcase oil separator and the vent hose, and indicating a presence of degradation associated with the vent hose based on the series of pressure pulsations and the monitoring window duration. In this way, diagnosis of a state of the vent hose may be reliably assessed without crankcase pressures confounding pressure measurements as recorded via the pressure sensor.

Abstract: Techniques for minimizing data flow from a first computing infrastructure hosting an email service platform to a second computing infrastructure at least partly hosting an email security platform that provides security analysis on emails of the email service. The email security platform may extract metadata from emails received at the first computing infrastructure, and send that metadata to the second computing infrastructure that is hosting a back end of the email service platform. The metadata extracted from the emails may include less confidential contained in an email, but enough information for the email security platform to determine whether an email is potentially malicious. Thus, the security analysis performed on emails to detect malicious attacks may be offloaded to the second computing infrastructure, but the metadata that leaves the first computing infrastructure and flows to the second computing infrastructure may be minimized by extracting meaningful metadata.
