Abstract: Method and apparatus for stress management in a searchable data service. The searchable data service may provide a searchable index to a backend data store, and an interface to build and query the searchable index, that enables client applications to search for and retrieve locators for stored entities in the backend data store. Embodiments of the searchable data service may implement a distributed stress management mechanism that may provide functionality including, but not limited to, the automated monitoring of critical resources, analysis of resource usage, and decisions on and performance of actions to keep resource usage within comfort zones. In one embodiment, in response to usage of a particular resource being detected as out of the comfort zone on a node, an action may be performed to transfer at least part of the resource usage for the local resource to another node that provides a similar resource.

Abstract: The invention relates to Chevrel-phase materials and methods of preparing these materials utilizing a precursor approach. The Chevrel-phase materials are useful in assembling electrodes, e.g., cathodes, for use in electrochemical cells, such as rechargeable batteries. The Chevrel-phase materials have a general formula of Mo6Z8 and the precursors have a general formula of MxMo6Z8. The cathode containing the Chevrel-phase material in accordance with the invention can be combined with a magnesium-containing anode and an electrolyte.

Abstract: Techniques are provided for testing alternative teaching approaches for specific portions of a curriculum. Test-triggering rules are established, each of which corresponds to a specific target-area. Each test-triggering rule specifies conditions which, if satisfied, indicate that a new teaching approach should be tested for the test-triggering rule's target-area. Once the test-triggering rules are established, the assessment results produced by students in instances of courses that implement the curriculum are monitored. If the assessment results satisfy the conditions, a revised teaching approach is selected for the target-area. The revision is then pushed out in waves where some course takers see the revision and others are held constant (A/B analysis). If a hypothesis is validated, then the appropriate revision can be permanently adopted.

Abstract: The invention relates to biodegradable iron alloy-containing compositions for use in preparing medical devices. In addition, biodegradable crystalline and amorphous compositions of the invention exhibit properties that make them suitable for use as medical devices for implantation into a body of a patient. The compositions include elemental iron and one or more elements selected from manganese, magnesium, zirconium, zinc and calcium. The compositions can be prepared using a high energy milling technique. The resulting compositions and the devices formed therefrom are useful in various surgical procedures, such as but not limited to orthopedic, craniofacial and cardiovascular.

Abstract: A system for backend conversion attribution of an advertisement served to a user device. The advertisement server provides an advertisement to the user device. The advertisement server receives user information from the user device. The advertisement server stores attributable event information and the user information into an attributable event record in a data store. Based on a user event, a conversion server receives conversion information and the user information from the user device. The conversion server stores the conversion information and the user information into a conversion record in the data store. An attribution server matches the attributable event record with the conversion record.

Abstract: A method and apparatus for utilizing a course skeleton for adaptive learning is provided. Based on student profile information and course goal information, a query is generated to dynamically determine which learning items should be presented to the student. The query, which is based on a particular learning goal, may differ from student to student, and therefore different students may be presented with different learning items to achieve the same learning goal. In addition, as new learning items is added to the learning item repository, the learning items returned by the query for a particular learning goal may change, even if the query used for the goal does not.

Abstract: A method and apparatus for competitive learning objects in a learning environment is provided. Based on the success that a student has with a particular learning item, a learning recommendation is generated for another student.

Abstract: Method and apparatus for monitoring and maintaining group health and membership in a searchable data service. The searchable data service may provide a searchable index to a backend data store, and an interface to build and query the searchable index, that enables client applications to search for and retrieve locators for stored entities in the backend data store. Embodiments of the searchable data service may implement a group health mechanism that may allow one or more components of the searchable data service to identify sets of nodes that the components may monitor. A group health component may be queried by the other components for automatically-refreshed health information about those nodes. The group health component may perform as a node failure detection mechanism. Node health information may be communicated among nodes at least in part using a gossip protocol.
