Abstract: Embodiments described herein provide for systems and methods for verifying authentic JIPs associated with ANIs using CLLIs known to be associated with the ANIs, allowing a computer to authenticate calls using the verified JIPs, among various factors. The computer builds a trust model for JIPs by correlating unique CLLIs to JIPs. A malicious actor might spoof numerous ANIs mapped to a single CLLI, but the malicious actor is unlikely to spoof multiple CLLIs due to the complexity of spoofing the volumes of ANIs associated with multiple CLLIs, so the CLLIs can be trusted when determining whether a JIP is authentic. The computer identifies an authentic JIP when the trust model indicates that a number of CLLIs associated with the JIP satisfies one or more thresholds. A machine-learning architecture references the fact that the JIP is authentic as an authentication factor for downstream call authentication functions.

Abstract: Embodiments described herein provide for authenticating callers to call centers using browser fingerprinting. A call center system or third-party analytics system includes a server that transmits notifications to a caller device that includes an interactive hyperlink or URL to a particular webpage. When a browser of the caller device navigates to the webpage, the server captures certain types of information about the caller device and generates a browser fingerprint for the caller device. The browser fingerprint is compared against a database of registered browser fingerprints to verify that the caller device of the current call is the registered, expected caller device. The server transmits the notification via any number of communication channels and protocols, such as text messages (e.g., SMS messages, MMS messages), emails, and push notifications associated with client-side software, among others.

Abstract: Provided are graphene-based nanopore and nanostructure devices, which devices may include an insulating layer disposed atop the graphene, which can be in a planar shape or nanostructured into a ribbon or other shapes, containing a single graphene layer or several layers. Graphene layers and nanostructures can be placed nearby horizontally or stacked vertically. Also provided are related methods of fabricating and processing such devices and also methods of using such devices in macromolecular analysis.

Abstract: Apparatus for testing the solubility of a medical dosage form includes a chamber (12) for holding a solvent medium (18), in the preferred embodiment a bicarbonate based buffer system. The apparatus also includes a pH probe (66) which is connectable to a supply of carbon dioxide (32, 34), as well as to a supply of helium (40), the supplies being controlled by a control unit (50). The control unit (50) monitors changes in pH of the solvent medium (18) and, as appropriate, feeds pH increasing and/or pH reducing gas from the supplies (32, 34, 40) into the chamber (12). The control unit (50) is able to maintain a uniform pH during testing or to provide a dynamically adjustable pH during testing, for example to three or more different pH levels in order to test the performance of a drug carrier at different levels of acidity or alkalinity for example, mimicking the conditions of the gastrointestinal tract.

Abstract: A supersonic aircraft engine axial fan that includes a rotating blade row having blades that receive a supersonic entry flow in the absolute frame and decelerate the flow to a lower supersonic or subsonic velocity exit flow while adding work to the flow to increase stagnation pressure. It is preferred that the lower velocity be subsonic. When the fan is combined with a suitably designed inlet, the propulsion system is compact and lighter in weight than conventional engines for supersonic aircraft.
