Can't surf, won't surf: The digital divide in mental health
BACKGROUND New health information technology (HIT) increasingly plays a role in health care as technology becomes cheaper and more widespread. However, there is a danger that those who do not use or have access to technology will not benefit from HIT innovations, thus creating a "digital divide". AIMS To assess the extent to which mental health service users have access to, skills in using an...
متن کاملSpeeding up SURF Imaging
Any good medical ultrasound imaging system must be able to resolve anatomical structures properly, and simultaneously provide adequate frame rate so that moving structures can be studied with ease. In a conventional imaging system these properties are related by a trade-off, but is it possible to have one and the other by applying more advanced post-processing to acquired RF data? Two new metho...
متن کاملThe surf is up
still remember that brief moment that revealed the astonishment of everyone in the audience. Andrew Cleland had just concluded his talk at the conference ‘Quantum Optics of Nanoand Micromechanical Systems’, which was held last July in Bad Honnef, Germany. He had taken us all by surprise. Andrew’s talk had begun as a review of recent results of his and John Martinis’ team — they had achieved an ...
متن کاملScaling surf zone turbulence
[1] Turbulence in the surf zone, the shallow region adjacent to the shoreline, has a key role in beach erosion, fertilization, dispersal, and larval settlement of marine invertebrates, and microbial contamination dilution in beach waters. Breakingwave generated (the dominant source) surf zone turbulence is understood poorly. A new surf zone turbulent dissipation rate scaling is derived, that co...
متن کاملGauge-SURF descriptors
In this paper, we present a novel family of multiscale local feature descrip1 tors, a theoretically and intuitively well justified variant of SURF which is 2 straightforward to implement but which nevertheless is capable of demon3 strably better performance with comparable computational cost. Our family 4 of descriptors, called Gauge-SURF (G-SURF), are based on second-order 5 multiscale gauge d...
