Tunable optical delay lines are one of the key building blocks in optical communication and microwave *** this work, tunable optical delay lines based on integrated grating-assisted contradirectional couplers are proposed and experimentally demonstrated. The device performance is comprehensively improved in terms of parameter optimization, apodization analysis, and electrode design. Tunable group delay lines of 50 ps at different wavelengths within the bandwidth of 12 nm are realized with a grating length of 1.8 mm. Under thermal tuning mode, the actual delay tuning range is around 20 ps at 7.2 V voltage. At last, a new scheme adopting an ultra-compact reflector for doubling group delay is proposed and verified, achieving a large group delay line of 400 ps and a large dispersion value up to 5.5 × 10~6 ps∕(nm · km) within bandwidth of 12 nm. Under thermal tuning mode, the actual delay tuning range is around 100 ps at 8 V voltage.

Objective Structural changes,like atrial fibrosis,may increase the likelihood of atrial fibrillation (AF) occurring in response to triggering *** influence of atrial amyloidosis is largely unknown. Methods Right atrial appendages(1 or 2 entire cross sections) were obtained from 27 patients undergoing open-heart *** amyloid was identified by Congo red staining and classified by *** was found every patient,significant amyloidosis(the Amyloidosis area accounted for more than 50%of the total area)was found in 20(74.1%) of 27 patients,and all deposits were immunoreactive for transthyretin(TTR) and trial natriuretic peptide(ANP),of which TTR is more significant. Results Fourteen(51.9%) patients suffered from persistent *** presence of amyloid correlated with age and P-wave duration and was related to sex,valve diseases,and the presence of AF(P=0.043). The association between atrial amyloid,AF,and P wave duration was independent of age and sex. According to multiple logistic regression analysis,amyloid was the only age- and sex-independent predictor for the presence of *** fibrosis was not a predictor for AF,but the amount of atrial fibrosis was related with atrial fibrillation. Conclusions Our study provides evidence that atrial amyloidosis affects atrial conduction and increases the risk of *** occurrence of atrial amyloidosis depends on age leading to the formation of an amyloid *** progression and consequences of atrial amyloidosis are then influenced by pathological conditions,such as valve *** correlation between atrial amyloidosis and atrial fibrillation suggests that these patients may not benefit from treatment with ACE inhibitors to reduce the amount of atrial fibrosis.

常规虚源点Marchenko自聚焦多次波预测方法只适用于预测不含自由表面的多次波模型,局限于压制层间多次波,该方法在构建上下行格林函数场前,必须从反射响应中去除所有与表面相关的多次波.本文对构建上下行Marchenko格林函数方程进行改进,得到了包含一次波、层间多次波和自由表面多次波的格林函数,利用改进的Marchenko自聚焦预测方法预测自由表面多次波.本文利用水平层状模型数据及SMARRT模型数据证明,改进后的Marchenko法预测海底相关的自由表面多次波效果较为理想,该方法避免了常规SRME自由表面多次波预测方法需要近道重构的缺陷,能够有效提高地震资料的信噪比和分辨率.

高精度的速度建模作为强非线性问题,需要一个比较正确的初始速度模型,而基于CMP道集的初始背景速度扫描估计是最稳健的方法。面对规模巨大的CMP道集,研究智能化的初始背景速度扫描估计方法是有必要的,其核心是合理的速度谱解释。这可以看作是基于速度谱解释人员的先验知识和层位约束信息,在Bayes决策意义下,在高维速度谱数据体中,以风险决策函数值最小为原则、挑选最合理的时间—速度(TV)对。为此,提出了一套以人工交互拾取速度谱逻辑思想为指导的决策框架。首先生成速度谱数据体及类叠加剖面,通过计算相干属性从类叠加剖面提取层位结构;再依据结构信息对速度谱能量团进行K均值聚类,对于每个类别以先验信息和数据空间分析的统计信息为约束,自动迭代搜寻使代价函数最小的TV对;最后通过插值平滑生成速度场,且经过基于统计量约束的质量控制降低了横向不连续性。该方法将层位信息的利用贯穿到从聚类到自动拾取的整个过程,并且将解释人员的先验认识及邻域拾取结果量化为自动拾取时的约束量,体现了速度谱解释的智能化,缩短了速度建模周期。
