Abstract: A combined hydrothermal liquefaction (HTL) and catalytic hydrothermal gasification (CHG) system and process are described that convert various biomass-containing sources into separable bio-oils and aqueous effluents that contain residual organics. Bio-oils may be converted to useful bio-based fuels and other chemical feedstocks. Residual organics in HTL aqueous effluents may be gasified and converted into medium-BTU product gases and directly used for process heating or to provide energy.

Abstract: Embodiments of the present invention provide systems and methods for generation and maintenance of verified data records. The system may receive a data submission from a user device over one or more communication channels and convert the data submission into a normalized text format for processing and analysis. The data submission may then be analyzed using one or more trained machined learning models in order to identify factual statements and modifiers within the data submission, and generate a confidence score of verified factual information based on corroboration with one or more additional data sources. Additionally, identified modifiers may be analyzed to determine positive or negative sentiment.

Abstract: Embodiments of the invention are directed to systems, methods, and computer program products for protection of network-based resource transfers via the use of encrypted tags. As such, the system allows for generation of unique encrypted tags which encode authorization parameters for denominations of electronic resources. The system may then authorize or deny requested network-based transfers by utilizing a decryption module to access the authorization parameters for a specific electronic resource denomination. Furthermore, the system may manipulate the encrypted tags to alter the authorization parameters or to track an electronic resource denomination across multiple network-based transfers.

Abstract: Verification of the identities of parties participating in network-based communication, such as telephone communication, including SMS/text communication, email communication and the like is provided. Communication identifiers (IDs) (e.g., telephone numbers, email addresses or the like) are verified as being associated with one or more communication parties and, in response, a verified communication (ID) database is established. The verified communication ID database is relied upon when a user/communication is selecting a communication ID as an address for an impending communication or receiving a communication for determining whether the communication ID is verifiably associated with a known communication party. If the communication ID is determined to be verifiably associated with a known communication party, a visual or audible output may be provided on the user's device or within the communication that indicates that the communication ID is verifiably associated with the known communication party.

Abstract: Resource event patterns are identified in previously conducted resource events based on historical resource event data and, in some embodiments, pending and/or previous resource event request data. Specifically, the resource event patterns indicate a timing pattern for when resource events included in the pattern are conducted. Based at least on the timing pattern, an optimal time or time period is determined for communicating a notification to the user that is configured to notify a user that a next occurrence of a time within the timing pattern is imminent and that a resource event within the resource event pattern is pending. The optimal time may be close in proximity of the next occurrence of the time within the timing pattern or, depending on other factors, such as user preference, resource volume due, resource volume availability, resource volume due in comparison to typical resource volume due, the optimal time may be farther out from the next occurrence of a time within the timing pattern.

Abstract: A thermoplastic filament comprising multiple polymers of differing flow temperatures in a geometric arrangement is described. A method for producing such a filament is also described. Because of the difference in flow temperatures, there exists a temperature range at which one polymer is mechanically stable while the other is flowable. This property is extremely useful for creating thermoplastic monofilament feedstock for three-dimensionally printed parts, wherein the mechanically stable polymer enables geometric stability while the flowable polymer can fill gaps and provide strong bonding and homogenization between deposited material lines and layers. These multimaterial filaments can be produced via thermal drawing from a thermoplastic preform, which itself can be three-dimensionally printed. Furthermore, the preform can be printed with precisely controlled and complex geometries, enabling the creation of a filament or fiber with a wide range of applications.

Abstract: Systems and methods are described for optimizing resource utilization in a communications network while also optimizing subscriber engagement with media content over the communications network. Requested content objects can be identified as delayable objects that can be queued for opportunistically delayed communication to both requesting and non-requesting subscribers. Queued delayed content objects are scored with an eye toward optimizing both subscriber engagement and utilization of opportunistically available communications link resources. For example, a storage manager calculates a likelihood that each subscriber will engage with the content if it is opportunistically delivered, and a scheduler calculates a priority order in which to queue each requested delayable content object.
