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...

Breakthroughs in Lyme Disease

Feature article: a panel of Lyme experts present bold new data demonstrating the therapeutic effects of Pentacyclic Alkaloid Chemotype U n c a r i a tomentosa (TOA-free Cat’s Claw) to be effective in the treatment of chronic Lyme disease. See page 3 Q & A section with Lyme experts about testing methods, natural therapies, neurotoxins associated with Lyme, and dealing with treatment-related toxi...

Breakthroughs in Nonlinear Silicon

We present an overview of the recent developments in nonlinear silicon photonics. There were significant advances in devices exploiting the ð2Þ and ð3Þ nonlinearities. Here, we discuss parametric amplification, wavelength conversion, supercontinuum generation, parametric oscillation, and frequency comb generation in siliconbased devices.

Molecular epidemiology of human pathogens: how to translate breakthroughs into public health practice, Stockholm, November 2011.

This report outlines the main conclusions from an expert consultation on molecular epidemiology held on 22–23 November 2011, hosted and organised by the European Centre for Disease Prevention and Control (ECDC) [1]. The consultation brought together researchers, microbiologists and public health experts to discuss how public health can benefit from the recent scientific and technological advanc...
