Abstract: A lithography system for extreme ultraviolet (EUV) radiation includes a housing (25) with an interior (24) containing a residual gas (27), and at least one gas-binding component (29) which is arranged in the interior (24) and has a gas-binding material for binding contaminating substances (28). The gas-binding component (29) has at least one flow duct (33) having at least one surface with the gas-binding material, with a gas flow of the residual gas (27) in the flow duct (33) having a Knudsen number of between 0.01 and 5, preferably between 0.01 and 0.5, in particular between 0.01 and 0.3, and with a casing (26) which encapsulates a beam path of the EUV lithography system (1) being arranged in the interior (24) of the housing (25). The casing (26) preferably has an opening (37) with a maintenance shaft (36) in which the gas-binding component (29) is arranged.

Abstract: Some embodiments are directed to magnetic puncture access and delivery systems and methods, including creating a passageway, such as a fistula, between two vessels or segments of a vessel. A system can include two catheters, each carrying a plurality of magnets along a longitudinal axis of each catheter.

Abstract: In one implementation, a method includes obtaining a data entry from a user of a device, and obtaining a first time entry related to a first time zone. The first time entry and the first time zone are selected by a user of the device and the device converts the first time entry to a second time in a second time zone associated with a user of the device. The device then stores the data entry with the second time in the device. The method and device can thus be used to schedule a meeting in a selected local time in selected time zone, which is then converted to a local time in a time zone associated with the device.

Abstract: A method of, and computer device for, processing a time-related data entry is provided. The method comprises obtaining the data entry from a user of the device, and obtaining a first time entry related to a first time zone. The first time entry and the first time zone are selected by a user of the device and the device converts the first time entry to a second time in a second time zone associated with a user of the device. The device then stores the data entry with the second time in the device. The method and device can thus be used to schedule a meeting in a selected local time in selected time zone, which is then converted to a local time in a time zone associated with the device.

Abstract: Techniques are provided for executing distinct aggregation operations in a manner that is more scalable and efficient than prior techniques. A three-stage technique is provided to parallelize aggregation operations that involve both grouping and multiple distinct-key columns. Such queries are handled by splitting rows into as many pieces as there are distinct aggregates in the query, and processing the row pieces. During the first-stage, a set of slave processes scans the rows of the base tables and performs partial duplicate elimination. During the second-stage, a set of slave processes completes the duplicate elimination and performs partial set function aggregation. During the third-stage, a third set of slave processes completes the set aggregation to produce the results of the distinct aggregation operation.
