Abstract:
... Photoacoustic imaging (PAI) is a rapidly developing imaging technique for both fundamental research and clinical applications. Recent studies revealed that PAI in the second near-infrared (NIR-II) region exhibits enhanced deep-tissue imaging capability, which benefits from reduced photon scattering, minimized background noise and increased applicable power in comparison to PAI in the first near-in ...

Deciding what to eat often implies a conflict between immediate goals (I need to eat, ideally something enjoyable) and long-term goals (I need to be healthy), particularly when choosing between foods superior on a hedonic dimension (referred to as vices) and foods superior on an utilitarian dimension (referred to as virtues). One sort of intervention that could potentially shift balance between sh ...

Abstract:
... Fibre migration in yarns is thought to take place in the spinning triangle (ST), where high tensioned edge fibres tend to compete for a low tension state by displacing inner fibres outwards to occupy the core position – the tension mechanism. The angular alignment of fibres in the drafted roving – the geometric mechanism – is also considered to contribute to this movement. Although there is an und ...
