The Essence of Aging
The idea that aging is a purposeful, programmed series of events is intuitively appealing based on its many conserved aspects and the demonstrated feasibility of modifying life span by manipulating single genes or pathways. Yet, the case for a nonadaptive basis of aging is strong and now all but generally accepted in the field. Here, we briefly review why the case for programmed aging is weak, ...

متن کاملDancing Combines the Essence for Successful Aging
dementia. A third line of research has focused on how a physically active lifestyle may protect against age related cognitive decline. In several studies it has been shown how elderly that frequently engage in physical activity also have preserved brain structure (Erickson et al., 2009) as well as cognitive functions (Hillman et al., 2008), compared with elderly that do not take part in physica...
متن کاملThe Essence of JavaScript
We reduce JavaScript to a core calculus structured as a small-step operational semantics. We present several peculiarities of the language and show that our calculus models them. We explicate the desugaring process that turns JavaScript programs into ones in the core. We demonstrate faithfulness to JavaScript using real-world test suites. Finally, we illustrate utility by defining a security pr...
متن کاملThe Essence of Multitasking
This article demonstrates how a powerful and expressive abstraction from concurrency theory—monads of resumptions—plays a dual rôle as a programming tool for concurrent applications. The article demonstrates how a wide variety of typical OS behaviors may be specified in terms of resumption monads known heretofore exclusively in the literature of programming language semantics. We illustrate the...
