This year marks 200 years of patient care at the Massachusetts General Hospital (MGH). In celebration of this milestone, a unique Grand Rounds case is presented. A 450-year-old rotund man admitted 60 times presents with a classic triad of periumbilical pain, bilateral plantar burns, and a frozen scalp. Although this triad may at first strike a cord of familiarity among seasoned clinicians, the ...

A general-purpose parallel raster processing programming library (pRPL) was developed and applied to speed up a commonly used cellular automaton model with known tractability limitations. The library is suitable for use by geographic information scientists with basic programming skills, but who lack knowledge and experience of parallel computing and programming. pRPL is a general-purpose progra...

An important ingredient in understanding such sentences is resolving the question of: level in/of what? protection from what? what sort of documents? danger from what? Each of these is an example coming from novels, television commercials, and news reports. In the first instance, it is from a commercial for a brand of computers. In the commercial, which is pushing the most recent version of tha...

Among cytoplasmic protein-tyrosine kinases (PTKs) Tec now forms a novel subfamily with recently identified Tec-related PTKs (Btk and ltk/Tsk). Tec is known to be abundantly expressed in myeloid cells, and multiple forms of Tec protein can be generated via the mechanism of alternative splicing. In this report, we have inveatigated 5“terminal diversity of the tec messages to demonstrate a predomi...

This paper investigates how portability of a model between different computer operating systems can lead to increased efficiency in code execution. The portability problem is not a trivial one, as many geographic models are designed to be run inside a set environment (Unix, Solaris, Linux, and Windows), and are further limited by hardware constraints. The SLEUTH urban growth model [K.C Clarke, ...

Software documentation represents a critical resource to the successful functioning of many enterprises. However, because it is static, documentation often fails to meet the needs of the many diverse users who are required to consult it on a regular basis in the course of their daily work. Software documentation is a rich resource that has not been fully exploited. Treatment of software documen...

Taking timely measures for management of the natural resources requires knowledge of the dynamic environment and land use practices in the rapidly changing postindustrial world. We used the SLUETH urban growth modeling and a multi-criteria evaluation (MCE) technique to predict and allocate land available to landfill as affected by the dynamics of the urban growth. The city is Gorgan, the capita...
