A method, apparatus, system, and signal-bearing medium that, in an embodiment, determine performance data for query optimization of a query directed to a database table having multiple partitions. The performance data for the query optimization is presented in a user interface, and an option is provided in the user interface to create a non-spanning index for any of the partitions mentioned in the performance data. In various embodiments, determining the performance data may include: determining the partitions that were unexpanded by the query optimization, determining the partitions that had a runtime estimate that was different from an actual query runtime by a threshold, determining whether any of the partitions had expansion forced by a client request, determining whether the query performed partition elimination, determining whether any of the partitions has an associated index that is unused by the query and that also has a key that is not present in all of the partitions, and determining a constraint for partition elimination.

Continual generation of index advice that includes generating an index advice for an index of a table in a computer database and recording values of statistical attributes of the index advice accumulated across repeated generations of the index advice. The generating and recording typically are carried out continually without user intervention. Embodiments include recording values of attributes of the index advice that specify an index. Typical embodiments also include, continually and without user intervention, recording values of attributes of the index advice that characterize usefulness of an index and recording values of attributes of the index advice that characterize cost of creating an index.

A system and method for updating a filtering system which controls access to a website/page between a local area network (LAN) and an Internet. The LAN includes an Internet gateway system coupled to a workstation and configured to receive a URL request. The system controls access to the website/page associated with the URL based on one or more categories that are associated with the URL. The Internet gateway system can determine the category that is associated with the URL by referencing a master database or requesting the category from a database factory. The database factory can receive URLs from multiple Internet gateway systems. The database factory determines whether the identifier was previously categorized by the database factory and provides the category to the Internet gateway system. Once the Internet gateway system has the category, it applies rules associated with the category and user to filter access to the requested website/page.

An exemplary embodiment provides a method of eliminating a shrinkage cavity in a metal ingot cast by direct chill casting. The method involves casting an upright ingot having an upper surface at an intended height. Upon completion of the casting, the lower tip of the spout is maintained below the molten metal near the center of the upper surface. The metal flow through the spout is terminated and a partial shrinkage cavity is allowed to form as metal of the ingot shrinks and contracts. Before the partial cavity exposes the lower tip of the spout, the cavity is preferably over-filled with molten metal, while avoiding spillage of molten metal, and then the flow of metal through the spout is terminated. These steps are repeated until no further contraction of the metal causes any part of the upper surface to contract below the intended ingot height.

Methods and systems of maintaining, evaluating, and providing therapy to a lung ex vivo. The methods and systems involve positioning the lung in an ex vivo perfusion circuit; circulating a perfusion fluid through the lung, the fluid entering the lung through a pulmonary artery interface and leaving the lung through a left atrial interface; and ventilating the lung by flowing a ventilation gas through a tracheal interface. Maintaining the lung for extended periods involves causing the lung to rebreath a captive volume of air, and reaching an equilibrium state between the perfusion fluid and the ventilation gas. Evaluating the gas exchange capability of the lung involves deoxygenating the perfusion fluid and measuring a time taken to reoxygenate the perfusion fluid by ventilating the lung with an oxygenation gas.

Compositions and methods for treatment of acute herpetic zoster and post herpetic neuralgia. The compositions comprise the combination of five or six components, namely, a carrier penetrator, an anti-inflammatory agent, a topical analgesic, a nonsteroidal anti-inflammatory penetrator, a direct-application anti-viral agent, and, optionally, an anti-convulsant and calcium-channel blocker. The compositions are formulated to be applied topically to the affected areas.
