Amplifying asymmetry with correlating catalysts

Photoswitchable catalysts: correlating structure and conformational dynamics with reactivity by a combined experimental and computational approach.

Photocontrol of a piperidine's Brønsted basicity was achieved by incorporation of a bulky azobenzene group and could be translated into pronounced reactivity differences between ON- and OFF-states in general base catalysis. This enabled successful photomodulation of the catalyst's activity in the nitroaldol reaction (Henry reaction). A modular synthetic route to the photoswitchable catalysts wa...

Correlating Text with Prosody

The prediction of prosody from text information has long been recognised as a requirement for natural sounding speech synthesis. While an examination of the relationship between text information and prosody typically focuses on the role of accent, duration and phrasing both from a statistical and rulebased perspective, this paper investigates the correlation between the similarities calculated ...

Amplifying Head Movements with Head-Mounted Displays

The head-mounted display (HMD) is a popular form of virtual display, due to its ability to immerse users visually in virtual environments (VEs). Unfortunately, the user’s virtual experience is compromised by the narrow field of view (FOV) it affords, which is less than half that of normal human vision. This paper explores a solution to some of the problems caused by the narrow FOV, by amplifyin...

Wish: Amplifying Creative Ability with Expert Crowds

We present Wish, a system that uses expert members of an online crowd to amplify a user’s ability to carry out complex creative tasks. When presented with an incomplete or rough draft of creative content (for example, writing, programming, or art), Wish finds and recruits an expert to suggest a possible realization of the user’s vision. Wish contributes a new approach to crowdsourcing complex w...
