For each pair of the plurality of pairs, a respective issue representation of core content of the respective issue and a linear expression of the one or more separate code snippets in a respective code representation is constructed and a model to correlate the respective code representation as resolving the respective issue representation is trained. The model is queried with a new issue and a selected one of the one or more separate code snippets. The model returns a classification indicating whether the selected one of the one or more separate code snippets is likely to resolve the new issue.

Abstract: A computer-implemented method, system and computer program product for identifying implicit dependencies between code artifacts. Co-defect association rules between code artifacts are generated, where such co-defect association rules include a prediction of how likely there will be a defect in a code artifact when there is a defect in an associated code artifact. After detecting a defect in a first code artifact, the co-defect association rules are reviewed to identify any code artifacts associated with the first code artifact. If there is a code artifact associated with the first code artifact, and if the probability of the associated code artifact being defected when the first code artifact is defected exceeds a threshold value, then a recommendation is made to the user to review not only the first code artifact that was defected but also its associated code artifact for a potential defect.

For each pair, the service constructs a respective issue representation of core content of the respective issue, constructs a linear expression of the one or more separate code snippets in a respective code representation, and trains a model to correlate the respective code representation as resolving the respective issue representation. The service queries the model with a new issue and a selected one of the one or more separate code snippets, wherein the model returns a classification indicating whether the selected one of the one or more separate code snippets is likely to resolve the new issue.

In embodiments, an adhesive that is configured to shrink up on curing can be applied (e.g., using a pick and place tool) to a location between the MEMS device and the PM. As a result of curing, the adhesive can pull the PM towards the MEMS device. In embodiments, an adhesive that is configured to expand as a result of curing can be applied to a location between the PM and a sidewall of the chassis. As a result of curing, the adhesive can push the PM towards the MEMS device. The adhesive can also secure the PM in place.

Abstract: Tubular casting processes, such as dip-coating, may be used to form substrates from polymeric solutions which may be used to fabricate implantable devices such as stents. The polymeric substrates may have multiple layers which retain the inherent properties of their starting materials and which are sufficiently ductile to prevent brittle fracture. Parameters such as the number of times the mandrel is immersed, the duration of time of each immersion within the solution, as well as the delay time between each immersion or the drying or curing time between dips and withdrawal rates of the mandrel from the solution may each be controlled to result in the desired mechanical characteristics. Additional post-processing may also be utilized to further increase strength of the substrate or to alter its shape.

Abstract: An artificial intelligence system monitors and records usage of a set of mobile devices that have been “paired” or grouped together. The system, over time, accumulates a history of times and locations associated with events that occur with respect to the devices. From this history, the system develops a usage model for the devices. The system, if it detects current usage diverges significantly from an expected usage, performs responsive actions which may include: notifying a user, via a paired device, that the mobile device may be lost or misplaced; command the “lost” mobile device to enter a reduced power state, to prolong battery life; and/or command the “lost” device to emit audible and/or visible signals intended to facilitate locating the device. In some embodiments, the system predicts an imminent loss of the device before it becomes lost, based on current usage vs. expected usage embodied in the model.
