Abstract: Methods, systems, and techniques for event notification. An event, such as a payment event that represents a payment transaction having been initiated, completed, or that the transaction is in progress, results in an event engine sending an upstream message to one or more servers. The one or more servers receive the upstream message, which is in a first format. The one or more servers convert the upstream message into a downstream message that is in a second format, such as an ISO 20022 format, and the downstream message is subsequently consumed by an event consumer. The event consumer may consume the downstream message in real-time relative to when the event occurs. Undelivered upstream or downstream messages may be stored in a dead letter channel repository for attempted redelivery.

Abstract: A single tracking URL collects tracking information for multiple tracking services based on multiple tracking URL templates. A dynamic link generator generates a tracking URL configured to collect tracking information requested by each of a set of enabled tracking URL templates. The tracking information is transmitted to the tracking services associated with the enabled tracking URL templates. Additionally or alternatively, a tracking URL is configured to redirect a consumer to one of a candidate set of destination URLs. A tracking URL includes a base URL, which is resolved to an IP address of a server of a particular tracking service. Based on tracking data associated with the tracking URL and/or digital body language associated with the consumer, the particular tracking service selects one of a candidate set of destination URLs associated with the tracking URL. A destination page corresponding to the selected destination URL is presented to the consumer.

Abstract: The present disclosure describes methods, devices, and non-transitory computer readable storage medium for managing lifecycle of a knowledge base (KB) in chatbot systems. The method includes receiving an update request and updating a current-version KB as a new current-version KB. The method also includes receiving a first test request from a knowledge point (KP) operator and determining whether the new current-version KB passes a first test; and in response to the determination that the new current-version KB passes the first test, submitting the new current-version KB as a new submit-version KB. The method further includes receiving a second test request from a KP manager and determining whether the new submit-version KB passes a second test; and in response to the determination that the new submit-version KB passes the second test, storing an original production-version KB as a pervious-version KB and submitting the new submit-version KB as a new production-version KB.

Abstract: The present invention provides a formulation and method for preparing a fibrous material comprising nanofibers. The formulation comprises (a) at least one polymer, (b) at least one solvent in which the at least one polymer is dissolved to provide a polymer solution, and (c) at least one functional additive that imparts functionality to the fibrous material. The at least one functional additive is dissolvable or suspensible in the polymer solution. The formulation is able to remove or reduce the concentration of bacteria, viruses and heavy metals while maintaining high filtration efficiency. The invention also relates to a fibrous material prepared by the formulation and applications of the fibrous material.

Abstract: An indirect bandgap thin film semiconductor circuit can be combined with a compound semiconductor LED such as to provide an active matrix LED array that can have high luminous capabilities such as for a light projector application. In another example, a highly efficient optical detector is achievable through the combination of indirect and direct bandgap semiconductors. Applications can include display technologies, light detection, MEMS, chemical sensors, or piezoelectric systems. An LED array can provide structured illumination, such as for a light and pattern source for projection displays, such as without requiring spatial light modulation (SLM). An example can combine light from separate monolithic light projector chips, such as providing different component colors. An example can provide full color from a single monolithic light projector chip, such as including selectively deposited phosphors, such as to contribute individual component colors to an overall color of a pixel.

The technique can also be used to adjust user strokes with respect to image gradients. The stroke refinement technique can comprise a local optimization, a semi-global optimization, and a global optimization to facilitate error tolerant image optimization.

Abstract: When a request is made to retrieve a guest physical page from memory and a page fault occurs, a guest virtual page address that corresponds to the guest physical page is identified along with addresses for guest virtual pages that are near the guest virtual page in the virtual address space. Each identified guest virtual page address is translated into a corresponding guest physical page address and the corresponding guest physical pages are loaded into memory.
