Prologue Introduction to Coarse Grained Simulation

Mixing of materials by small scale turbulent motion is a critical element of many flow systems of interest in engineering, geophysics, and astrophysics. Numerical simulation plays a crucial role and turbulent mixing predictability is a major concern. Small scale resolution requirements focus typically on those of continuum fluid mechanics described by Navier–Stokes (NS) equations; different req...

Welcome to Silence

Editorial Welcome to Silence [1], a new open-access journal devoted to RNA silencing and other pathways directed by non-coding RNAs. Silence springs from the extraordinary, yet brief, history of RNA silencing. In just two decades, we have seen the anomalous properties of plant and fungal transgenes connect with a series of amazing experiments in which injected double-stranded RNA triggered sile...

Editorial: Prologue to guidelines for stroke care.

Prologue to Guidelines for Stroke Care • This prologue makes clear the factors that provided incentive for creating the Joint Committee for Stroke Facilities to prepare and publish the series of articles appearing regularly in Stroke (beginning with the May-June, 1972, issue), best described by the general title of Guidelines for Stroke Care. It points out in admirable fashion the many facets o...

Prologue to Set Theory and Logic

First of all, the proof of a theorem is a message. A proof is not a beautiful abstract object with an independent existence. No mathematicians grasps a proof, sits back, and sighs happily at the knowledge that he can now be certain of the truth of his theorem. He runs out into the hall and looks for someone to listen to it. He bursts into a colleague’s office and commandeers the blackboard. He ...
