Abstract: The invention provides for a low pH disinfectant composition that includes a relatively low amount of alcohol. Also provided is an article of manufacture that includes a textile and the composition, as well as methods of using the composition and article of manufacture (e.g., for reducing the number of microbes located upon a substrate, for killing or inhibiting a broad spectrum of microorganisms, for killing or inhibiting spore forming bacteria, and/or for disinfecting a substrate). The composition can optionally include a stable residual antimicrobial compound, thereby providing a combination of high-level disinfection and long-lasting residual effect.

Abstract: Provided herein is a composition that includes: (i) chelator (e.g., ethylenediaminetetraacetic acid (EDTA)), (ii) buffer system (e.g., potassium phosphate dibasic and sodium hydroxide), (iii) cleaner (e.g., diethyl glycol monoethyl ether), (iv) solubilizer (e.g., propylene glycol), and (v) diluent (e.g., water), wherein the composition has a pH of at least about 9.5. Also provided is a method of cleaning a medical device that includes contacting the medical device with the composition described herein, for a period of time effective to clean the medical device. Subsequent to the cleaning, the medical device can optionally be disinfected, dried, and stored.

Abstract: An online system selects advertisements for presentation a user based on characteristics of the user. The online system monitors performance of advertisements based on a goal for the advertisement and a time interval for achieving the goal. During a time period within the time interval, the online system determines an actual performance of the advertisement and compares the actual performance to a portion of the goal associated with the time period. If the actual performance does not satisfy the portion of the goal associated with the time period, the online system expands targeting criteria of the advertisement to increase a number of users eligible to be presented with the advertisement.

Abstract: An online system selects advertisements for a user based on characteristics of the user. The online system presents advertisements to the user having targeting criteria satisfied by the characteristics of the user. To increase the number of users eligible to be presented with an advertisement, the online system increases the users eligible to be presented with the advertisement to include users that do not meet targeting criteria included in the advertisement. The online system obtains a percentile of users based on a performance metric associated with the advertisement and determines a cutoff measure of affinity based on the percentile and measures of affinity between various users and the advertisement. A user is eligible to be presented with the advertisement if a measure of affinity between the user and the advertisement is greater than the cutoff measure of affinity for the advertisement.

Abstract: A composition that includes: (a) hydrogen peroxide; (b) at least one of an inorganic acid and an organic acid; (c) chelator; (d) anticorrosive agent; and (e) surfactant. Kits that include the composition, as well as methods of using the composition (e.g., as a disinfectant) are provided.

Abstract: The dental composite includes a resin base and a combination of a short-cut fiber filler and a particulate filler. The short-cut fibers may be made of a glass or a polymer, and may have an average length of about 2 mm to about 6 mm. The particulate filler includes a ground structural filler, which consists of particles having an average particle size of between about 0.05 ?m and about 0.5 ?m, and a microfiller, which consists of particles having a mean particle size of about 0.04 ?m or less. The cured dental composite provides high strength, an improved wear resistance, a dramatically improved fracture resistance and a high gloss retention in simulated extended clinical wear.

Abstract: A wheeled vehicle is disclosed where that vehicle includes at least one disk, i.e. wheel, and a plurality of permanent magnets disposed around that wheel. The vehicle further includes a frame, where the wheel is rotatably connected to that frame. The vehicle further includes a source of electric power, and one or more electromagnet assemblies, each assembly comprising a first electromagnetic pole and a second electromagnet pole, where the first electromagnet pole and the second electromagnet pole are separated by a gap, and where one or more electromagnet assemblies are disposed on the frame such that each of the plurality of permanent magnets sequentially passes through the gaps in each assembly as the wheel rotates. The vehicle further includes a control unit capable of receiving power from the power source and selectively providing power to the one or more electromagnet assemblies.
