Abstract: Enabling quick feature delivery is essential for product success and is therefore a goal of software architecture design. But how may we determine if and to what extent an architecture is “good enough” to support feature addition and modification, or determine if a refactoring effort is successful in that features may be added more easily? The applications may use Feature Space and Feature Dependency, derived from a software project's revision history that capture the dependency relations among the features of a system in a feature dependency structure matrix (FDSM), using features as first-class design elements. The applications may also use a Feature Decoupling Level (FDL) metric that may be used to measure the level of independence among features.

Abstract: One embodiment of the invention provides a variable pitch impeller for a blood pump. The variable pitch impeller includes: a flexible polymer defining a plurality of blades extending from a first end to a second end, the blades having a resting non-zero pitch; an external shaft coupled to a first end of the flexible polymer; and an internal shaft received within the external shaft and coupled to the second end of the flexible polymer. The internal shaft and the external shaft are rotatable with respect to each other to achieve a blade pitch between about 0.0001° and about 2,880°.

Abstract: In an effort to discover therapies for treating diseases caused by EBV, a novel screening assay for identifying compounds that reactivate EBV latent infection and a family of small molecules based on a tetrahydrocarboline backbone were discovered. Specifically, the compounds have the structure of the formula (I), wherein R1-R11 are defined herein and activate/reactivate EBV in a variety of cell types in a patient and are, therefore, useful in preventing or treating EBV-positive cancer, optionally with an anti-viral agent. In screening these compounds, novel compositions, EBV-positive cell lines, and methods are provided.
