A hybrid on-chip optomechanical transducer for ultrasensitive force measurements.
Nanoscale mechanical oscillators are used as ultrasensitive detectors of force, mass and charge. Nanomechanical oscillators have also been coupled with optical and electronic resonators to explore the quantum properties of mechanical systems. Here, we report an optomechanical transducer in which a Si(3)N(4) nanomechanical beam is coupled to a disk-shaped optical resonator made of silica on a si...
متن کاملStimulation and characteristics of secondary oesophageal peristalsis in normal subjects.
The study evaluates the triggering and characteristics of secondary oesophageal peristalsis in 25 healthy volunteers. Secondary peristalsis was stimulated by rapid intraoesophageal injection of boluses of air and water, and by a five second oesophageal distension with a balloon. Air and water boluses triggered secondary peristalsis that started in the proximal oesophagus regardless of injection...
متن کاملPower of oesophageal peristalsis can be controlled voluntarily.
The hypothesis that oesophageal peristalsis can be modified voluntarily was explored. Six healthy male volunteers and eight female patients with angina like chest pain underwent oesophageal manometry. Each was asked to take a series of swallows, and to vary their size, in random order, by taking either a big gulp or a little swallow. None of the subjects experienced difficulty in doing so. In b...
متن کاملAnomalies of peristalsis in idiopathic diffuse oesophageal spasm.
Oesophageal manometry revealed 'interrupted peristalsis'--proximal sequential contraction with simultaneous pressure increases in the mid-oesophagus and sequential contraction distally--and abnormally slow distal propagation of peristalsis in seven of a consecutive series of 12 patients with idiopathic diffuse oesophageal spasm (IDOS). These two abnormalities occurred together in six patients. ...
متن کاملEffect of dystonic movements on oesophageal peristalsis in Sandifer's syndrome.
A 5 year old girl with gross gastrooesophageal reflux had pronounced dystonic neck movements that resolved after fundoplication and resolution of the oesophagitis (Sandifer's syndrome). Oesophageal manometry before operation showed that peristalsis improved when she tilted her head to one side. Dystonic posturing may promote acid clearance from the distal oesophagus.
