摘要： 与docker相关的集群平台逐渐成为SaaS平台的主流框架体系,而且在企业单位中被广泛采用,各大商业企业都在容器及集群管理方向开展未来云平台项目.因为基于Kubernetes的SaaS架构式的集群平台,不仅具有功能模块化、资源可重组化的主要优点,而且能够保障集群可靠性和安全性.因此,面对空间复杂的服务要求和有限的资源能力,基于Kubernetes的SaaS平台成为首选集群平台.同样,平台状态和服务信息的监控成为空间环境下保障系统健康程度的重要方式.主要介绍利用Lens开源工具以实现对SaaS微服务进行监控的方式,首先介绍这2种工具的优势,接下来介绍监控系统的实现方式,并说明如何利用2种工具构建监控系统.

摘要： Quantum light sources serve as one of the key elements in quantum photonic technologies. Such sources made from semiconductor material, e.g., quantum dots (QDs), are particularly appealing because of their great potential of scalability enabled by the modern planar nanofabrication technologies. So far, non-classic light sources based on semiconductor QDs are currently outperforming their counterparts using nonlinear optical process, for instance, parametric down conversion and four-wave mixing. To fully exploring the potential of semiconductor QDs, it is highly desirable to integrate QDs with a variety of photonic nanostructures for better device performance due to the improved light-matter interaction. Among different designs, the photonic nanostructures exhibiting broad operation spectral range is particularly interesting to overcome the QD spectral inhomogeneity and exciton fine structure splitting for the generations of single-photon and entangled photon pair respectively. In this review, we focus on recent progress on high-performance semiconductor quantum light sources that is achieved by integrating single QDs with a variety of broadband photonic nanostructures i.e. waveguide, lens and low-Q cavity.

摘要： Background: It is unclear whether post-operative errors after toric intraocular lens implantation would be more amenable to pre-operative correction with a fixed adjustment or a correction ratio that scales with the magnitude of pre-operative astigmatism. Purpose: To investigate the effect of pre-operative anterior corneal astigmatism orientation on outcomes of toric intraocular lens implantation in a large population. Methods: A retrospective cohort study of 625 patients undergoing refractive lens exchange through a superior clear corneal incision with Oculentis M-Plus toric intraocular lens implantation at an Optical Express, Inc. located in the United Kingdom and Ireland. Patients were stratified by axis of astigmatism on automated keratometry as with-the-rule, against-the-rule, or oblique. Analysis of visual acuity and refractive outcomes was performed using American National Standards Institute (ANSI) guidelines on astigmatic corrections with non-vector as well as vector analyses. Analysis was limited to one eye per patient. Results: Patients who had with-the-rule (WTR) astigmatism, compared with oblique and against-the-rule (ATR), had higher vector magnitudes of surgically induced refractive correction (2.89D, 2.55D, 2.42D;p Conclusions: Refractive lens exchange surgery using toric intraocular lenses overcorrected patients who had with-the-rule astigmatism. Degree of overcorrection did not vary with severity of pre-operative astigmatism. Incorporation of axis of astigmatism in lens selection and reduction of astigmatic correction among with-the-rule patients by an absolute value of 0.25D - 0.35D, rather than proportional adjustments, may reduce cylindrical over-correction.

摘要： Background: Many reasons can lead to an aphakia without adequate capsular support for implantation of a posterior chamber intraocular lens (IOL), such as intraoperative unintentional rupture of posterior capsule during phacoemulsification, planned intracapsular cataract extraction, ocular trauma and lens dislocation due to congenital and acquired causes. Purpose: To compare Y-shaped intra-scleral fixation of a posterior chamber IOL with retro pupillary fixation of an iris-claw intraocular lens (IOL) for Aphakic eyes without sufficient capsular support as respects safety, visual recovery and complications of both methods. Patients and Methods: One hundred Aphakic eyes were arbitrarily distributed between two groups. Group A included 50 eyes treated with retropupillary fixation of iris claw lens and group B included 50 eyes treated with Y-shaped intra-scleral fixation technique. Preoperative, intraoperative and postoperative data were analysed including best corrected visual acuity (BCVA), intraocular pressure (IOP), surgical time, intraoperative problems, IOL malposition and postoperative complications. Following up on patients was carried out for at least six months. Results: The mean duration of surgery was 21 ± 5.3 min in group A and was 53.4 ± 6.9 min in group B (p-value 0.05). IOL tilt was found in 0 (0%) eyes in group A and in 5 (10%) eyes in group B (p 0.05). Conclusion: The results of our study indicated that both methods are satisfactory in correcting aphakia without sufficient capsular support as regards postoperative best corrected visual acuity (BCVA);however the surgical technique of retropupillary iris claw lens is easier, shorter, with low intra- and postoperative complications and safer than those used for intra-scleral fixation of IOL. But for eyes which lack both iris and capsular support, a scleral fixation of a posterior chamber IOL remains the only option.

摘要： Purpose: To evaluate the histopathologic alterations of organelles in the epithelium of the anterior lens capsule. Methods: The interventional study included 26 eyes;of which 11 had non-proliferative diabetic retinopathy (diabetic group) and cataract, and 15 had age-related cataract (control group). We investigated the anterior lens capsule in patients with diabetes mellitus by using electron microscopy and to compare it between diabetic eyes and healthy eyes. Anterior capsule samples were obtained by circular continuous capsulorhexis during phacoemulsification procedures. All the samples were fixed and conventionally processed for electron microscopy analysis. Results: Demographic characteristics of the diabetic group and the control group were similar (p > 0.05). In the diabetic group, electron dense cells with an apoptotic appearance were seen and these cells had an apoptotic nucleus and prominent mitochondrial crystalysis. In addition, there was dilatation of the endoplasmic reticulum cistern. In the control group, lens epithelial cells and all their elements had a normal pattern. Neither cells with an apoptotic appearance nor mitochondrial crystalysis was seen, but there was dilatation of the endoplasmic reticulum cistern. Conclusions: Diabetes mellitus can engender structural abnormalities of organelles in the epithelium of the anterior lens capsule including mitochondrial crystalysis, dilatation of the endoplasmic reticulum cistern and apoptotic dense nucleus. It can be suggested that diabetes mellitus affects organelles of anterior lens epithelium in eyes with cataracts, while it causes non-proliferative changes in the retina.

摘要： Objective: To determine the protective effects of intraocular lens implantation without viscoelastic agents on corneal endothelial cells. Methods: Patients with age-related cataract were randomly divided into two groups: Group A (24 patients, 30 eyes) underwent phacoemulsification and intraocular lens implantation without viscoelastic agents, and group B (21 patients, 30 eyes) underwent phacoemulsification and intraocular lens implantation with viscoelastic agents. The corneal endothelial cell counts, percentages of hexagonal cells, and central corneal thicknesses were evaluated at 1 week, 1 month, and 6 months after surgery. Results: There was no significant difference in preoperative basic characteristics between the two groups (p > 0.05). The postoperative corneal endothelial cell count and percentage of hexagonal cells in both groups decreased compared with preoperative values at 1 week, 1 month, and 6 months after surgery, and the decrease of group A was significantly lower than that of group B at all time points (p p > 0.05). Conclusions: Compared with regular intraocular lens implantation, intraocular lens implantation without viscoelastic agents is less damaging to corneal endothelial cells, resulting in greater corneal safety.
