Sinclair and several other prominent gerontologists are presently seeking human therapies based on the long-standing observation that lifelong restriction of caloric intake considerably extends both the healthy and total life span of nearly all species in which it has been tried, including rodents and dogs. Drugs that elicit the gene expression changes that result from caloric restriction might, these workers assert, extend human life span by something approaching the same proportion as seen ...

 The von Neumann Model for Computing Machines

At the highest level, the major hardware components of most boards can be classifi ed into fi ve major categories: Central processing unit (CPU). The master processor. Memory. Where the system’s software is stored. Input device(s). Input slave processors and relative electrical components. Output device(s). Output slave processors and relative electrical components. Data pathway(s)/bus(es). Interconnects the other components, providing a “highway” for data to travel on from one compone...
