Abstract: This disclosure relates to identifying and presenting differences between a plurality of recorded executions of an executable entity. One or more models are created over the plurality of recorded prior executions of at least a portion of an executable entity. These models include at least one of (i) a control flow model, or (ii) a data model. An anomalous model data point is identified within these models, and a first location in at least one of the plurality of recorded executions that corresponds to the anomalous model data point is identified. A second location in the at least one of the plurality of recorded executions is also identified. This second location is causal to the anomalous model data point at the first location. The identity of the first and/or second locations in the least one of the plurality of recorded executions is presented.

Abstract: Techniques are provided to use historic execution state information to visualize tracepoint data. For example, historic execution state information corresponding to an application's previous execution is accessed. This historic execution state information was collected while the application was executing. After correlating the historic execution state information to the application's code, a tracepoint is associated with a portion of the code. Consequently, when the code is replayed based on the historic execution state information, the tracepoint causes a behavior of that code portion to be logged while the code is replayed uninterrupted. The code is then actually replayed based on the historic execution state information. During the replay, the tracepoint causes the behavior of the code portion to be logged. The logged behavior is visualized on a user interface.

Abstract: Designs, strategies and methods for forming tube shaped batteries are described. In some examples, hermetic seals may be used to seal battery chemistry within the tube-shaped batteries. This may improve biocompatibility of energization elements. In some examples, the tube form biocompatible energization elements may be used in a biomedical device. In some further examples, the tube form biocompatible energization elements may be used in a contact lens.

Abstract: The present approach assigns a code to each node class of a data tree modeling a database. The node class codes may be used to generate a node class path for each node class. This class path may be used as a discriminator to reference a given node class or portion of the tree including the class path and may be stored in a field of the database and/or cached. Use of the class path in query operations reduces the complexity of certain queries, thereby speeding up query performance.
