Abstract: A system and method of metadata refinement using behavioral patterns is disclosed. In some embodiments, user behavioral data for results of a search query is received. The results can include an untagged item and a plurality of tagged items. A determination can then be made that the tagged items have been assigned a plurality of types of metadata. The untagged item can then be identified as a candidate to be tagged with at least one of the plurality of types of metadata assigned to the tagged items. In some embodiments, the user behavioral data comprises clickstream data indicating that a user selected the untagged item and at least one of the tagged items during a single search event.

Abstract: This disclosure provides systems, methods, and apparatus related to laser ablation spectrometry systems. In one aspect, a system comprises a microscope, a laser, a continuous flow probe, and a gas confinement device. The laser is positioned to emit light through an objective lens of the microscope. The continuous flow probe is coupled to a spectrometer. An end of the continuous flow probe is positioned proximate a sample and between the sample and the objective lens. The gas confinement device defines a gas inlet, a chamber, a platform, a wall surrounding the platform, a plurality of vents, and a plurality of channels. Each of the plurality of vents is positioned to direct a gas substantially parallel to the platform, and each of the plurality of vents is defined in the wall. The plurality of channels is operable to provide fluid communication between the chamber and the plurality of vents.

Abstract: Method and system is described to effectuate a single action upload of images from a mobile device. When the system detects activation of a visual control provided by an on-line service, the system activates a camera provided with the mobile device of the user, detects a resulting image captured by the camera, and uploads the resulting image from the mobile device of the user to a destination computing device. The destination computing device can be a server system associated with the on-line service.

Abstract: A drink container with convertible spouts is provided. The drink container includes a lid that can be removably coupled to a container body having a volume to hold fluids.
