Abstract: Systems and methods are disclosed for dynamically analyzing and providing the quality of one or more content items at the time, or substantially close to the time, they are received by a data processing system. The systems and methods described herein can maintain and update the quality score for improving previously created content items after they have been published. The one or more content items can include one or more assets (e.g., one or more headlines, one or more descriptions, images, video, etc.). The data processing system can use numerical analysis methods to determine an overall quality (e.g., estimated clicks) of the content items received by the data processing system using a trained model.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for providing a customized content item. A method includes: receiving a content request; identifying one or more user device attributes and/or a context of the request; identifying a content item having distribution parameters matching the context and/or user device attributes and including one or more variables that are resolved based on the context or the one or more user device attributes; selecting, as modifying data, a subset of feed data to which the one or more variables for the content item will be resolved, including: identifying the feed data, evaluating the feed data to locate the subset; and selecting the modifying data; and modifying the content item, at least in part, by including, in place of the one or more variables, the selected modifying data; and providing the modified content item in response to the request.

Abstract: Razors are described herein. In some instances the razors include a safety razor blade unit that includes a guard, a cap, and at least two blades with parallel sharpened edges located between the guard and cap. A first blade defines a blade edge nearer the guard and a second blade defines a blade edge nearer the cap. The first blade has a cutter force greater than the cutter force of the second blade. In some instances the razors provide a comfortable shave having improved closeness.

Abstract: The invention includes a tankless liquid heater that employs a series of chambers, each having a plurality of heating tubes, with heating elements positioned thereon, and a control unit comprising a switch, controller, and power distributor to control the flow and heating of liquid in the system. In one embodiment, the control unit takes input from a liquid flow sensor that monitors the passage of liquid through the system, a temperature sensor adapted to monitor liquid temperature, and a current leakage sensor adapted to monitor the current leakage in the system. In response to these sensors, the control controller actuates the relay between an closed position, which allows current from the power distributor to pass to a plurality of heating elements, and an open position, which prevents the current from flowing from the power distributer to the plurality of heating elements.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for creating advertisements are disclosed. In one aspect, a method includes receiving an advertisement request that includes user context data. An advertisement having distribution parameters matching the user context data is identified. The identified advertisement can include one or more variables that are resolved based on the user context data. A proper subset of feed data to which the one or more variables for the advertisement will be resolved can be selected based on the user context data and performance measures for portions of the feed data that have been previously used to resolve the one or more variables. The advertisement is modified, at least in part, by including, in place of the one or more variables, the selected modifying data. The modified advertisement is provided in response to the advertisement request.

Abstract: Methods treating razors blade cutting edges having an adherent polyfluorocarbon coated thereon are described. The coated razor blade edges are treated with a solvent, which partially removes the coating from the razor blade edge. Addition of an antioxidant to the solvent improves the effectiveness of the treatment.

Abstract: A method of forming a polyfluorocarbon coating on a razor blade cutting edge comprises subjecting a fluorocarbon polymer having a molecular weight of at least 1,000,000 in dry powder form to ionizing irradiation to reduce the molecular weight of the polymer forming a dispersion of the irradiated polymer in a volatile organic liquid, spraying the dispersion on to a razor blade cutting edge, and heating the coating obtained to sinter the polyfluorocarbon. The polyfluorocarbon preferably is polytetrafluoroethylene and irradiation preferably is effected to obtain a telomer having a molecular weight of about 25,000.
