摘要： Radio frequency (RF) shields used with magnetic resonance imaging (MRI) apparatus may experience gradient field induced eddy currents and RF field induced eddy currents. These eddy currents can cause the RF shield to heat up at an undesirable rate. RF shields are designed to have a desired degree of RF shielding and a desired heating attribute. Design goals for RF shields include gradient field transparency and RF field opacity, both of which can be influenced by eddy currents. Example methods identify a gradient field that will induce eddy currents and identify an RF field that will induce eddy currents. If a region on the RF shield is identified where the desired heating attribute will not be achieved, then a pattern of axial cuts and azimuthal cuts can be made in the RF shield to reduce gradient eddy current heating in the RF shield while maintaining desired RF shielding.

摘要： This invention provides an oral apparatus and method capable of alleviating or curing snore and obstructive sleep apnea by applying a negative pressure through a mini oral interface to the oral cavity. The mini oral interface creates a secure connection between the interface and mouth or teeth and prevents the interface from falling off. The oral interface also provides fixation between upper and lower lips (or tooth) and prevents opening of patient's mouth during sleeping. The negative pressure pulls the tongue toward upper palate and also pulls the soft palate forward as well. By moving the tongue and the soft palate in a forward direction, the patency of the upper airway near the pharynx is maintained to prevent sleep-disordered breathing. The negative pressure will pull the lips inward to close the mouth ad prevent air from entering the oral cavity from atmosphere. The negative pressure will also pull the soft palate into contact with the rear surface of the tongue to create a seal that prevents the air from entering the oral cavity through the nasal airway.
摘要翻译：本发明提供一种能够通过将迷你口腔界面施加负压口腔来缓解或治愈打鼾和阻塞性睡眠呼吸暂停的口腔装置和方法。迷你口腔界面在接口和嘴或牙齿之间产生牢固的连接，并防止接口脱落。口腔界面还提供上唇和下唇（或牙齿）之间的固定，并防止睡眠期间患者口腔的打开。负压将舌头拉向上腭，并将软腭向前拉。通过向前移动舌头和软腭，保持咽部附近上呼吸道的通畅，防止睡眠呼吸紊乱。负压会将嘴唇向内拉，以闭合嘴巴，防止空气从大气进入口腔。负压也会使软腭与舌头的后表面接触，以产生防止空气通过鼻气道进入口腔的密封。

摘要： The selective growth of vertically aligned, highly dense carbon nanotube (CNT) arrays using a thermal catalytic chemical vapor deposition (CCVD) method via selection of the supporting layer where the thin catalyst layer is deposited on. A thin iron (Fe) catalyst deposited on a supporting layer of tantalum (Ta) yielded CCVD growth of the vertical dense CNT arrays. Cross-sectional transmission electron microscopy revealed a Vollmer-Weber mode of Fe island growth on Ta, with a small contact angle of the islands controlled by the relative surface energies of the supporting layer, the catalyst and their interface. The as-formed Fe island morphology promoted surface diffusion of carbon atoms seeding the growth of the CNTs from the catalyst surface.
