Abstract: A sodium-cooled nuclear reactor includes at least one electromagnetic pump assembly and a backflow reduction pipe. The backflow reduction pipe may include an inlet, an outlet, at least one tubular section having a first length and a first diameter, and at least one fluid diode section between the inlet and the outlet.

Abstract: A leverage curve progression adjustment assembly for a rear suspension of a two wheeled vehicle, such as a mountain bicycle, adjusts the rate of change (slope/progression) of the leverage curve for the vehicle's suspension linkage while maintaining the same leverage ratio at the suspension's fully extended position. The leverage curve progression is adjusted by translating the first and second mounting locations of a spring/damper member along an axis of the spring/damper member using mounting hardware segments with spring/damper mounting holes positionable at multiple locations, such as flip chips with offset mounting holes, and/or mounting plates with mounting holes located at different locations.

Abstract: Certain aspects of the present disclosure provide techniques for managing a search engine based on search performance metrics. An example method generally includes dividing a set of search history data into a first subset of search history data and a second subset of search history data. The first subset of data is associated with interaction with search results, and the second subset of data is associated with non-interaction with search results. A first quality score is generated for searches in the first subset of data. A second quality score is generated for searches in the second subset of data based on different search intents identified for each temporally related group in the second subset of data. An overall quality score is generated for a search engine, and one or more actions with respect to the search engine are taken based on the overall quality score.

Abstract: A bicycle rear suspension based on a four bar configuration comprises an upper connecting member, a rear axle floating member, a lower connecting member, an upper shock actuation member, a pushrod member, and a damper member. A pivotable coupling couples a first location on the upper shock actuation member to a location on the front triangle, another pivotable coupling couples a second location on the upper shock actuation member to a first location on the pushrod member, and another pivotable coupling couples a second location on the pushrod member to a location on the lower connecting link member. The upper shock actuation member is pivotably coupled to the damper member. The upper shock actuation member and the pushrod member and the geometries of their respective pivotable couplings allow the leverage curve for the suspension to be defined independently of their kinematic traits, thereby providing improved rider feel and/or performance.

Abstract: An audio system with first and second discrete audio drivers that are in a listening space, wherein each driver is configured to radiate sound into the listening space, and wherein the radiated sound from each driver at a listening location in the listening space has a frequency, phase, and magnitude. The audio system is configured to modify a phase of the sound radiated by at least one of the first or second drivers such that a phase response difference between the first and second drivers at the listening location is closer to zero degrees than it was before the modification.

Abstract: A technique for identifying deviations in patterns of data traffic between host devices communicating over a network involves establishing a baseline traffic distribution by categorizing data traffic during a learning period. The baseline traffic distribution includes a list of categories and a metric value and a measure of variability of the metric value for each category in the list. An observed traffic distribution is generated by categorizing data traffic during an observation period. The observed traffic distribution includes a list of categories and a metric value associated with each category in the list. An alarm is generated in response to at least one of the metric values of the categories of the observed traffic distribution deviating significantly from the corresponding metric value in the baseline traffic distribution based on a pair-wise comparison of the observed metric values with respective thresholds established for corresponding categories of the baseline traffic distribution.
