The Brillouin scattering is one of the strongest nonlinear optical effects in dielectrics[1].In particular,the backward Brillouin scattering(BBS)provides an efficient method to achieve low-noise optical gain for active photonics[2]and the coherent interconnects between 10 GHz phonons and photons[3].However,previous studies on BBS are primarily limited to the unconfined phonons[1]or phonon confined in suspended structures[4-6].

调谐黏滞质量阻尼器(Tuned Viscous Mass Damper,TVMD)是一种有效的被动惯容减震装置,本文针对地震作用下建筑结构TVMD阻尼比增效效应与优化设计展开研究。将TVMD对结构自身阻尼耗能功率的控制效果归纳为TVMD等效附加阻尼比,并基于随机振动理论推导了等效附加阻尼比的理论表达式。为了使TVMD更具实际应用价值,TVMD理论上应取得比同阻尼系数的黏滞阻尼器(VD)更大的等效附加阻尼比,这一现象定义为TVMD阻尼比增效效应,并定义了阻尼比增效系数来量化评估阻尼比增效效应。将等效附加阻尼比和阻尼比增效系数均作为优化目标,提出了TVMD最优设计参数理论解。参数分析结果表明,本文解具有良好的稳定性和适用性,为了更高效地发挥阻尼比增效效应,推荐TVMD质量比不超过0.3或阻尼比不超过0.1。以某七层标准钢框架结构作为工程算例展示了TVMD设计流程,并验证了本文解的有效性和优越性。算例分析结果表明,使用本文解设计TVMD能显著放大其阻尼元件变形,表现出了理想的阻尼比增效效应。与传统解相比,本文解还具有另一个明显优势,即保证TVMD的减震效果优于同阻尼系数的VD,不存在减震效率问题。

This research aimed to examine the diagnostic accuracy and clinical significance of endoscopic ultrasonography(EUS)in the context of small rectal neuroendocrine neoplasms(NENs).A total of 108 patients with rectal subepithelial lesions(SELs)with a diameter of<20 mm were included in the *** diagnosis and depth assessment of EUS was compared to the histology *** prevalence of NENs in rectal SELs was 78.7%(85/108).The sensitivity of EUS in detecting rectal NENs was 98.9%(84/85),while the specificity was 52.2%(12/23).Overall,the diagnostic accuracy of EUS in identifying rectal NENs was 88.9%(96/108).The overall accuracy rate for EUS in assessing the depth of invasion in rectal NENs was 92.9%(78/84).Therefore,EUS demonstrates reasonable diagnostic accuracy in detecting small rectal NENs,with good sensitivity but inferior *** may also assist physicians in assessing the depth of invasion in small rectal NENs before endoscopic excision.
