  • 简介:AbstractIntroduction:Early intervention in patients with congenitally disconnected pulmonary artery improves long-term outcome.Case presentation:We present 3 cases of isolated disconnected pulmonary artery in the absence of associated structural heart disease during a period of 3 years.Conclusion:Transcatheter stenting of the feeding ductus arteriosus re-established pulmonary artery flow and growth. Successful surgical repair was achieved, and normal perfusion and complete function of the ipsilateral lung were regained.

  • 简介:Deduplication通常在两个企业存储系统和云存储被使用了。克服性能挑战为选择恢复deduplication系统的操作,solid-state-drive-based(即,基于SSD)读的缓存能为由缓冲加快被部署流行动态地恢复内容。不幸地,经常的数据更改由古典缓存计划导致了(例如,LRU和LFU)显著地弄短SSD一生当在SSD减慢I/O进程时。处理这个问题,我们建议新解决方案砍缓存极大地由扩大比例象I/O性能一样改进SSD的write耐久性长期流行(砍)在写进基于SSD的缓存的数据之中的数据。砍缓存保留很长时间在SSD缓存砍数据减少的时期缓存代替的数字。而且,它在deduplication集装箱阻止不得人心或不必要的数据被写进SSD缓存。我们在一个原型deduplication系统实现了砍缓存评估它的性能。我们的试验性的结果显示砍缓存弄短潜伏选择与仅仅deduplicated数据的5.56%能力以小基于SSD的缓存的成本由37.3%的一般水准恢复。重要地,砍缓存由9.77的一个因素改进SSD一生。砍缓存为一个成本效率的基于SSD的读的缓存解决方案提供到的证据表演增加性能选择为deduplication恢复系统。

  • 简介:摘要INTRODUCTIONThis case study explores the gains in hand function in an individual with a chronic spinal cord injury (SCI). The intervention was long-term paired associative simulation (PAS). We aimed to provide PAS until full recovery of hand muscle strength occurred, or until improvements ceased.CASE PRESENTATIONA 46-year-old man with traumatic C7 AIS B tetraplegia was administered PAS three times per week. After 24 weeks, PAS was combined with concomitant motor training of the remaining weak hand muscles. Outcome measures included the manual muscle test (MMT), motor-evoked potentials (MEPs), F-responses, hand functional tests, and the spinal cord independence measure (SCIM).DISCUSSIONAfter 47 weeks of PAS the subject had improved self-care and indoor mobility and was able to perform complex motor tasks (SCIM score improved from 40 to 56). His left hand regained maximum MMT score (total 75; increase of score from baseline condition 19); the effect remained stable in the 32-week follow up. In the right-hand muscles, MMT scores of 4-5 were observed in follow up (total 71; increase from baseline 48). Improved values were also observed in other outcomes. This is the first demonstration of long-term PAS restoring muscle strength corresponding to MMT scores of 4-5 in an individual with chronic SCI. The effect persisted for several months, indicating that PAS induces stable plastic changes in the corticospinal pathway.
