PLoS Genetics, 2014 Dietary restriction extends longevity in organisms ranging from bacteria to mice and protects primates from a variety of diseases, but the contribution of each dietary component to aging is poorly understood. Here we demonstrate that glucose and specific

Angewandte Chemie International Edition, Accepted Article.O‐aminophenol oxidases, a specialized subclass of type‐III copper proteins, play a crucial role in the biosynthesis of bioactive nitrosophenols which display antiretroviral and blood cholesterol lowering activity. Another related subclass of type‐III copper proteins, tyrosinases, closely resemble o‐aminophenol oxidases both structurally and ...

Speex: A Free Codec For Free Speech [PDF]
arXiv, 2016 The Speex project has been started in 2002 to address the need for a free, open-source speech codec. Speex is based on the Code Excited Linear Prediction (CELP) algorithm and, unlike the previously existing Vorbis codec, is optimised for transmitting speech for low latency communication over an unreliable packet network. This paper presents an overview

A New Robust Frequency Domain Echo Canceller With Closed-Loop Learning Rate Adaptation [PDF]
, 2016 One of the main difficulties in echo cancellation is the fact that the learning rate needs to vary according to conditions such as double-talk and echo path change. Several methods have been proposed to vary the learning. In this paper we propose a new closed-loop method where the learning rate is proportional to a misalignment parameter, which is in ...

Ruthenium Catalyzed ortho‐Arylation Reaction of Benzoic Acids with Arylthianthrenium Salts
Angewandte Chemie International Edition, Accepted Article.Arylthianthrenium salts have become key intermediates for late‐stage functionalizations of drug‐like molecules. Ruthenium‐phosphine catalysts are now shown to enable their use as aryl sources in high‐yielding ortho‐C–H arylations of benzoic acids. The arylthianthrenium salts are converted chemo‐selectively, leaving aryl halides and boronates untouched.
