摘要：研究目的:评价护士定期随访对管理肺癌患者的效果。 设计:随机对照试验。 研究地点:英国东南部的一所肿瘤专科医院和三家癌症研究中心。 研究对象:203例完成初始治疗并预期存活3个月以上的肺癌患者。 干预措施:对非住院患者,护士定期随访与传统预后随访进行比较。

摘要：The use of near infrared, high intensity femtosecond laser pulses for the inscription of long period fiber gratings in photonic crystal fiber is reported. The formation of grating structures in photonic crystal fiber is complicated by the fiber structure that allows wave-guidance but that impairs and scatters the femtosecond inscription beam. The effects of symmetric and asymmetric femtosecond laser inscriptions are compared and the polarization characteristics of long period gratings and their responses to external perturbations are reported.
