| 1 | High-efficiency,large-area,topologyoptimized metasurfaces显示文摘Metasurfaces are ultrathin optical elements that are highly promising for constructing lightweight and compact optical systems.For their practical implementation,it is imperative to maximize the metasurface efficiency.Topology optimization provides a pathway for pushing the limits of metasurface efficiency;however,topology optimization methods have been limited to the design of microscale devices due to the extensive computational resources that are required.We introduce a new strategy for optimizing large-area metasurfaces in a computationally efficient manner.By stitching together individually optimized sections of the metasurface,we can reduce the computational complexity of the optimization from high-polynomial to linear.As a proof of concept,we design and experimentally demonstrate large-area,high-numerical-aperture silicon metasurface lenses with focusing efficiencies exceeding 90%.These concepts can be generalized to the design of multifunctional,broadband diffractive optical devices and will enable the implementation of large-area,high-performance metasurfaces in practical optical systems. | Thaibao Phan David Sell Evan W.Wang Sage Doshay Kofi Edee Jianji Yang Jonathan A.Fan | 2019 | Light(Science & Applications)2019,8,1: | 12 |
| 2 | PREDICTING THE DEPTH OF EROSION IN RESERVOIRS FOLLOWING DAM REMOVAL USING BANK STABILITY ANALYSIS显示文摘Dam removal has emerged in the U.S. as a critical concern for river management. Of particular interest is predicting the quantity of sediment that will be eroded from a reservoir following dam removal, which necessitates predicting the geometry a channel will approach as it forms in the reservoir. The geometry and sediment characteristics of the Koshkonong River were measured as it adjusted to the removal of the Rockdale Dam. Bank stability modeling was used as a tool for predicting the maximum depth of the evolving channel and general agreement was found between depths predicted with the model and those observed up to one year following dam removal. Model sensitivity analysis showed strong control of bank heights by groundwater levels in the reservoir sediment, as well as some control by vegetation established on the sediment surface. Long-term monitoring is needed to assess the accuracy of the model, but preliminary agreement is encouraging for applying this model and similar models to future dam removals. | Martin W.

| 4 | 广泛经皮针刀筋膜切断术联合脂肪移植术:一种治疗掌腱膜挛缩的新疗法显示文摘背景手术切除治疗掌腱膜挛缩症复发率高且康复时间延长。本文将介绍一种新型微创手术替代治疗掌腱膜挛缩症的方法及其成果。方法过程包括采用广泛经皮针刀筋膜切断术将束带完全松解,并与真皮分离。随后,由此产生的松弛组织用以自体脂肪填充。术后伸直位制动1周,然后,建议术后3~6个月患者白天可以正常用手,夜间伸直位固定。本组患者共91例(99只手),手术在迈阿密和鹿特丹进行;对50例患者的手部伸展角度进行测量(平均随访44周)。结果近端指间关节挛缩的治疗效果显著,伸展角度由61°改善至27°,掌指关节挛缩的伸展角度由37°改善至-5°。94%患者在2~4周内手部恢复正常功能,95%患者对结果非常满意。无新的瘢痕生成,大部分恢复了柔软的手掌脂肪垫。发生了1例神经损伤的并发症,1例术后切口感染,4例复杂区域疼痛综合征。结论这一新的微创技术缩短了康复时间,增加了缺损的皮下脂肪组织,产生了柔软无痕的皮肤。并且有能力处理多个掌指纹,可解决整只手的异常情况。治疗过程安全有效,尤其对首次治疗者。目前,前瞻性随机对照研究过程充分确定了其治疗掌腱膜挛缩症的作用。(循证医学证据等级:Ⅳ级,疗法) | Steven E.

| 10 | Epiretinal membrane following pars plana vitrectomy for rhegmatogenous retinal detachment repair显示文摘AIM: To determine the rate and possible contributors for post-pars plana vitrectomy(PPV) epiretinal membrane(ERM) in patients treated for rhegmatogenous retinal detachment(RRD). METHODS: This prospective, nonrandomized study comprised 47 consecutive patients(47 eyes) with acute RRD treated with 23 G post-PPV. All participants were followed prospectively for 6 mo for the development of ERM using spectral domain optical coherence tomography. Preoperative and intraoperative data were collected by questionnaires to surgeons. Main outcome measure was the percentage of the ERM formation following post-PPV for RRD. RESULTS: ERM developed postoperatively in 23 eyes(48.9%), none necessitated surgical removal. There was a statistically significant difference between patients with and without ERM postoperatively in preoperative best corrected visual acuity(median log MAR 1.9 vs 0.3, respectively;P=0.003) rate of macula-off(69.6% vs 37.5%, respectively, P=0.028), and rate of ≥5 cryo-applications(55.6% and 18.8%, respectively, P=0.039). ERM developed mainly between the 1st and 3rd months of follow-up. Macula-off status increased the risk of ERM, with the odds ratio of 3.81(P=0.031). CONCLUSION: ERM is a frequent post RRD finding, and its development is associated with macula-off RRD. | Ruti Sell Amir Sternfeld Ivan Budnik Ruth Axer-Siegel Rita Ehrlich | 2019 | International Journal of Ophthalmology(English edition)2019,12,12: | 2 |
