The silencing of gene expression by small interfering RNAs has been recognized for only a relatively short time, but this has transformed our understanding of both transcriptional and post-transcriptional gene regulatory mechanisms. Multiple pathways culminate in formation of an RNA-induced silencing complex (RISC) containing a member of the...

There is nothing simple about creating effective, cross-browser, JavaScript code. In addition to the normal challenge of writing clean code you have the added complexity of dealing with obtuse browser complexities. To counter-act this JavaScript developers frequently construct some set of common, reusable, functionality in the form of...

This Handbook explores the history of mathematics under a series of themes which raise new questions about what mathematics has been and what it has meant to practice it. It addresses questions of who creates mathematics, who uses it, and how. A broader understanding of mathematical practitioners naturally leads to a new appreciation of what...

In 1997. there were over 100 commercially supported embedded operating systems, none of which had more than a minority share of the overall embedded OS market, not to mention countless thousands of others developed for specific projects (cell phones, radar arrays, networking equipment, etc.) that had no application developer base beyond that...

My interest in oscillators started many years ago when I was an undergraduate student and one of the laboratory experiments was the design of a Colpitts oscillator. It was amazing to see how a sinusoidal signal appeared when the power supply was turned on. What an interesting way of controlling the motion of electrons in the circuit!...
