Context. A promising model for normal Type Ia supernova (SN Ia) explosions are delayed detonations of Chandrasekhar-mass white dwarfs, in which the burning starts out as a subsonic deflagration and turns at a later phase of the explosion into a supersonic detonation. The mechanism of the underlying deflagration-to-detonation transition (DDT) is unknown in detail, but necessary conditions have b...

Do-It-Yourself (DIY) open-source hardware allows users of technology (and/or their community members) to create their own tools and designs. In recent years, resources and components for DIY electronics have emerged that allow for the development of customized, affordable assistive technologies. These resources, which can be shared online, open doors for new ways to create and share technology ...

In a fully soluble system from resting human neutrophils, activation of the respiratory burst oxidase under defined conditions was found to follow first-order kinetics. The manner in which this first-order activation process varied with the concentrations of the individual components in the activating system suggested the following. 1) The respiratory burst oxidase occurs in two forms that can ...

Speaker adaptation for TTS applications has been receiving more attention in recent years for applications such as voice customisation or voice banking. If these applications are offered as an Internet service, there is no control on the quality of the data that can be collected. It can be noisy with people talking in the background or recorded in a reverberant environment. This makes the adapt...

When individuals lose the ability to produce their own speech, due to degenerative diseases such as motor neurone disease (MND) or Parkinson’s, they lose not only a functional means of communication but also a display of their individual and group identity. In order to build personalized synthetic voices, attempts have been made to capture the voice before it is lost, using a process known as v...

The problems of composing and inverting schema mappings specified by source-to-target tuple-generating dependencies (st-tgds) have attracted a lot of attention, as they are of fundamental importance for the development of Bernstein’s metadata management framework. In the case of the composition operator, a natural semantics has been proposed and the language of second-order tuple generating dep...
