Abstract: Techniques for context-based queryless presentation of recommendations are described. Without receiving an explicit query, an inferred query is determined based on a first set of context signals associated with a recommendation triggering event. Items matching the inferred query are selected based on a second set of one or more context signals associated with the recommendation triggering event. One or more results items identifying the one or more matching items are caused to display. A result items may be displayed in association with an explanation that identifies context values used to select an item for recommendation or one or more attributes of the item that are relevant to a user or the inferred query.

Abstract: According to various embodiments, a system includes a fuel controller configured to control a fuel transition between a first flow of a first fuel and a second flow of a second fuel into a fuel nozzle of a combustion system. The fuel controller is configured to adjust a third flow of a diluent in combination with the second flow of the second fuel to maintain a pressure ratio across the fuel nozzle above a predetermined operating pressure ratio.

Abstract: A method for recycling AgInCd control rod absorber bar material from a used control rod from a nuclear power plant includes sectioning AgInCd absorber bar from a used control rod into a first section and a second section, the first section having a higher radioactivity than the second section; and recycling the material of the second section of the AgInCd absorber bar.

Abstract: Devices and methods for use in detecting an optical signal, such as from a fluorescent agent, and converting it to a visible signal are provided. Aspects of the devices include a first light source that emits light onto a region of interest such as a body tissue, body fluid, or agent such as a fluorescent agent introduced into the body; a detector for detecting light emitted or reflected from the region of interest; and a visible light source that emits visible light onto the region of interest, where the color or intensity of the visible light is selected based on the amount of light at one or more wavelengths detected by the detector. Devices and methods of the invention find use in a variety of applications, such as in applications in which it is desired to identify an anatomical structure during surgery, without the need to eliminate ambient light.

Abstract: An online system provides users with tools to annotate publications and share such annotations with other users. Publications annotated by a community of users become a richer source of information for the community.

Abstract: The present invention provides a system and method for selectively removing one or more organic and inorganic and also preferably one or more inorganic contaminants from plating baths. More particularly, the invented method relates to the use of a source of energy in combination with chemical oxidants, alone or in conjunction with a catalyst to oxidize organic contaminants in the plating bath to a level such that the electroplating bath can be recovered and reused after appropriate chemical adjustment. The oxidative treatment method may be a continuous process or a batch process that is performed in a single pass. Residual organics, if desired and chloride ions in the bath are removed from the solution by a chemisorption or physisorption treatment. Inorganic contaminants are removed from the electroplating bath by selective ion exchange resins or electrodialysis, while particulate and suspended colloidal particles are removed by filtration before the treated plating bath is recycled.

Abstract: Optical alignment apparatus includes a first element mounting a first lens and a light source and a second element mounting a second lens and a light receiving structure. The first lens is placed a first distance from the light source and is constructed to collimate light received from the light source. The first and second elements are mounted relative to each other to position the second lens a third distance from the first lens and to receive the collimated light from the first lens. The second lens is positioned a second distance from the light receiving structure to focus the collimated light on the light receiving structure. The first and second lens are constructed so that the first and second distances are dependent upon each other and the third distance is independent of the first and second distances.

Abstract: The optoelectric alignment apparatus and lens system includes a glass ball positioned to receive light from a light source along an optical axis. A second lens is positioned to receive light from the glass ball and to supply the received light to a light receiving structure. The glass ball provides most of the optical power of the lens system so that the second lens provides only minor optical correction. The lens system is mounted by means of a molded plastic body that extends axially along the optical axis with the second lens molded into the body. The body includes a light inlet end and a light outlet in a surface lateral to the optical axis and defines a glass ball receiving cavity adjacent the light inlet end fixedly gripping the glass ball.
