Abstract: Systems, methods, and devices can be utilized to verify wireless local area networks (WLANs) using fingerprints. An example method includes identifying a received fingerprint comprised in an advertisement message that is received by a user equipment (UE) at a time and within a coverage area. A source of the advertisement message is determined to be a rogue WLAN by determining that the received fingerprint is different than a verified fingerprint transmitted by an authorized WLAN at the time and in the coverage area. The UE outputs an alert indicating the rogue WLAN.

Abstract: Interactive search trust assessment systems and techniques are described. In some examples, an interactive search trust assessment system receives a prompt associated with a search for information about an object. The prompt is based on a user input and data from a data structure. The interactive search trust assessment system processes the prompt using a trained machine learning model to generate a response. The response is responsive to the prompt. The response includes the information about the object retrieved from the data structure as a result of the search. The interactive search trust assessment system generates a response trust score associated with the response. The response trust score is based on one or more trust scores associated with the information about the object retrieved from the data structure. The interactive search trust assessment system outputs the response based on the response trust score exceeding a threshold.

Abstract: This document describes a process of producing gel microparticles, which are consistent in size and morphology. Through the process of coacervation, large volumes of gel microparticle slurry can be produced by scaling up reactor vessel size. Particles can be repeatedly dehydrated and rehydrated in accordance to their environment, allowing for the storage of particles in a non-solvent such as ethanol. Gel slurries exhibit a Bingham plastic behavior in which the slurry behaves as a solid at shear stresses that are below a critical value. Upon reaching the critical shear stress, the slurry undergoes a rapid decrease in viscosity and behaves as a liquid. The rheological behavior of these slurries can be adjusted by changing the compaction processes such as centrifugation force to alter the yield-stress. The narrower distribution and reduced size of these particles allows for an increase in FRESH printing fidelity.

Abstract: An infrastructure system facilitates trace-based surveys to query users their experiences with pull request workflows. For example, the infrastructure system may receive from a client device associated with a user a pull request for making one or more changes to a programming code repository. The infrastructure system may generate a trace based on a pull request workflow including operations for making the change(s). The trace includes spans, each of which correspond to one or more operations in the pull request workflow. The infrastructure system generates log files, each log file includes data logged during the one or more operations of a span. The log files may be stored as a dataset of the trace. The infrastructure system may transmit a survey to the client device based on the dataset. The infrastructure system may also modify the pull request workflow based on the user's response to the survey.

Abstract: A system preventing an impaired driver from starting a vehicle has a mobile application executing on a portable communication device having a display screen, user-operable input elements, a microphone audio input, a speaker and wireless communication circuitry, a hardware component integrated into wiring of the vehicle, the hardware component comprising a normally open switching element operable by wireless signal from the portable communication device, that when open prevents the vehicle from starting, and an interactive interface displayed on the display screen. The interactive interface requests specific action from a candidate driver, records the candidate driver's action, determines if the action indicates the candidate driver is impaired, and if not impaired, signals the hardware component wirelessly to close the normally open switching element for a predetermined time, enabling the candidate driver to start the vehicle.
