Testing Web applications by modeling with FSMs

Abstract: Researchers and practitioners are still trying to find effective ways to model and test Web applications This paper proposes a system-level testing technique that combines test generation based on finite state machines with constraints We use a hierarchical approach to model potentially large Web applications The approach builds hierarchies of Finite State Machines (FSMs) that model subsystems of the Web applications, and then generates test requirements as subsequences of states in the FSMs These subsequences are then combined and refined to form complete executable tests The constraints are used to select a reduced set of inputs with the goal of reducing the state space explosion otherwise inherent in using FSMs The paper illustrates the technique with a running example of a Web-based course student information system and introduces a prototype implementation to support the technique

Identification and functions of usefully disordered proteins.

Abstract: Publisher Summary This chapter illustrates that protein disorder is encoded by the amino acid sequence and that protein disorder is essential for many important biological functions. An ordered protein contains a single canonical set of Ramachandran angles, whereas a disordered protein or region contains an ensemble of divergent angles at any instant and these angles interconvert over time. Intrinsically disordered protein can be extended (random coil–like) or collapsed (molten globule–like). The latter type of disorder typically includes regions of fluctuating secondary structure, so disorder does not mean absence of helix or sheet. Both types of disorders have been observed in apparently native proteins. Intrinsic disorder might not be encoded by the sequence, but rather might be the result of the absence of suitable tertiary interactions. If this were the general cause of intrinsic disorder, any subset of ordered sequences and any subset of disordered sequences would likely be the same within the statistical uncertainty of the sampling. On the other hand, if intrinsic disorders were encoded by the amino acid sequence, any subset of disordered sequences would likely differ significantly from samples of ordered protein sequences.

Stripe rust of wheat and barley in North America: a retrospective historical review.

Abstract: This retrospective review deals with the sequence of events and research progress on control of stripe rust of wheat and barley in North America. From the discovery of stripe rust in 1915, it documents the early years of stripe rust research, the 20-year hiatus when stripe rust was not considered important and research was almost nonexistent, the short period in the 1950s when stripe rust became prevalent in the central United States, and the severe epidemics in the West in the 1960s and the associated revival and expansion of research. Finally, it covers 1968 to 2001 when the earlier information was consolidated and combined with results of new research to enable prediction and control of stripe rust, especially in the West.
