Assessing potential propulsion breakthroughs.

The term, propulsion breakthrough, refers to concepts like propellantless space drives and faster-than-light travel, the kind of breakthroughs that would make interstellar exploration practical. Although no such breakthroughs appear imminent, a variety of investigations have begun. During 1996-2002 NASA supported the breakthrough propulsion physics project to examine physics in the context of b...

ANATOMY OF BREAKTHROUGHS Breakthroughs in Automatic Speech Recognition Technology

This paper will give a short introduction to history behind the development of the most important technologies used in Automatic Speech Recognition systems today. We start from the 1950’s when the first digit recognizer was introduced and explain key points of the following decades until the 1980’s when the Hidden Markov Models became standard. After the Hidden Markov Models, we jump to the cur...

In 2012, research teams used these detectors to fi ngerprint decay products from the long-sought Higgs boson and determine its mass, successfully testing a key prediction of the standard model of particle physics. See the Breakthrough of t...

Breakthroughs and blind ends

Evolution of a through gut with an oral and an anal opening conceivably marked a breakthrough in early animal history, as basal animals have a blind ending gut with only one opening. How this occurred, and whether a through gut evolved only once or several times is a matter of debate. Perhaps the different modes by which guts develop in animal embryos that are used for the classification of ani...
