Non-contact wide-field viewing system-assisted scleral buckling surgery for retinal detachment in silicone oilfilled eyes

AIM:To evaluate scleral buckling(SB)surgery using a noncontact wide-field viewing system and 23-gauge intraocular illumination for the treatment of rhegmatogenous retinal detachment in silicone oil(SO)-filled eyes.METHODS:Totally 9 patients(9 eyes)with retinal detachment in SO-filled eyes were retrospectively analyzed.All patients underwent non-contact wide-field viewing system-assisted buckling surgery with 23-gauge intraocular illumination.SO was removed at an appropriate time based on recovery.The patients were followed up for at least 3mo after SO removal.Retinal reattachment,complications,visual acuity and intraocular pressure(IOP)before and after surgery were observed.RESULTS:Patients were followed up for a mean of 8.22mo(3-22mo)after SO removal.All patients had retinal reattachment.At the final follow-up,visual acuity showed improvement for 8 patients,and no change for 1 patient.The IOP was high in 3 patients before surgery,but it stabilized after treatment;it was not affected in the other patients.None of the patients had infections,hemorrhage,anterior ischemia,or any other complication.CONCLUSION:This new non-contact wide-field viewing system-assisted SB surgery with 23-gauge intraocular illumination is effective and safe for retinal detachment in SO-filled eyes.

Ecosystem Services of Grazed Grasslands in the Flooding Pampa

The Flooding Pampa grasslands are the last remnant of the Rio de la Plata grasslands in Argentina.Anthropo-genic interventions have led to severe degradation and,as a result,the ecosystem services provided by the grass-lands are declining,in terms of provisioning,regulating,and supporting services.We synthesized the existing literature on the ecosystem goods and services provided by these grasslands under grazing in different conditions and conservation status.We found that plant and animal diversity and primary production are the most studied ecosystem services,while climate regulation,water supply,nutrient cycling,meat production and erosion control,in that order,are less studied.Cultural services are under-researched.Continuous grazing and glyphosate spraying are the main drivers of grassland degradation.Controlled grazing and conservative stocking rates have been shown to reverse degradation and demonstrate that livestock production is compatible with ecosystem conserva-tion by maintaining regulating and provisioning services.As these management strategies are poorly integrated,improving their implementation will require important changes in farmers’decisions and the development of policies that create the economic conditions for this to happen.Research is needed to understand the conditions that prevent the knowledge generated from being transferred to producers and translated into practices that would improve the provision of ecosystem services.

Sickle cell retinopathy and systemic disease

Sickle cell disease(SCD)is a widespread hemoglobinopathy that results in significant patient morbidity and mortality.Vascular occlusion can cause acute pain,acute chest syndrome,and avascular necrosis,while hemolysis and endothelial disruption can cause ischemic stroke,leg ulcers,pulmonary hypertension,and priapism.All ocular and orbital structures can be affected by SCD ischemic events,including orbital bone infarction,ischemic optic neuropathy,retinal artery occlusion,hyphema,secondary glaucoma,sickle cell maculopathy,and sickle cell retinopathy.Proliferative sickle cell retinopathy(PSR)is the most common cause of vision loss.Untreated PSR can lead to macular ischemia,vitreous hemorrhage,and tractional retinal detachment.Ophthalmic screening exams and multimodal imaging can lead to earlier detection of sickle cell retinopathy and improved patient outcomes.SCD patients undergoing vitreoretinal surgery may require coordination of care with hematologists to avoid ischemic complications.While hydroxyurea was the only United States Food and Drug Administration approved treatment for several decades,patients with SCD now have several more treatment options.Despite the United States screening all infants for SCD,there can be delays in diagnosis and treatment.This review article aims to provide an overview of sickle disease for the ophthalmologist,and to discuss emerging treatment options and current management of SCD ocular complications.

Surgical Approaches in Primary Rhegmatogenous Retinal Detachment: A Systematic Review and Meta-Analysis Comparing Vitrectomy vs. Vitrectomy Combined with Scleral Buckling, Lens-Sparing vs. Phako Procedures

Aim: This study aimed to assess and compare the functional and anatomical results of pars plana vitrectomy (PPV) alone versus PPV combined with scleral buckling (SB), and lens-sparing versus phaco-procedures for treating rhegmatogenous retinal detachment. Methods: A comprehensive literature search was performed using the Web of Science, MEDLINE, EMBASE, and Cochrane Library databases to retrieve comparative studies. The main objective was to assess the BCVA, while reattachment rates and ocular adverse events were considered secondary measures. Rev Manager software was used for statistical analysis. Results: The literature search identified 10 articles comprising 1518 eyes, with 682 eyes in the PPV group, 193 eyes in the lens-sparing versus phaco-procedure group, and 643 eyes in the combined PPV and SB surgery group. Quality assessment revealed a low risk of bias in most domains. The meta-analysis results revealed a significant difference in postoperative BCVA between the PPV and PPV combined with SB groups (WMD = −0.17, 95% CI [0.27, 0.07], p = 0.001). The primary reattachment rates were 82.80% for PPV alone and 87.52% for PPV combined with SB (p = 0.34). The final reattachment rates did not differ significantly between PPV and PPV combined with SB (99% vs. 99.8%;RR = 1.00, 95% CI [1.01, 0.99], p = 0.96). PPV alone demonstrated a significantly reduced risk of macular edema compared to PPV combined with scleral buckling (9.9% vs. 23%;p = 0.006). The incidences of macular hole development (p = 0.46), recurrent retinal detachment (p = 0.27), proliferative vitreoretinopathy development (p = 0.48), epiretinal membrane proliferation (p = 0.77), and limited choroidal hemorrhage (p = 0.69) were not significantly different between the two groups. Conclusions: These findings suggest that PPV alone may be a more effective treatment option in terms of visual acuity (VA) improvement, lower risk of macular edema and cataract development. However, there was no significant difference in VA improvement or complication rates between the lens-sparing and phaco-procedure groups. .

Spatial Multi-Presence System to Increase Security Awareness for Remote Collaboration in an Extended Reality Environment

Enhancing the sense of presence of participants is an important issue in terms of security awareness for remote collaboration in extended reality.However,conventional methods are insufficient to be aware of remote situations and to search for and control remote workspaces.This study pro-poses a spatial multi-presence system that simultaneously provides multiple spaces while rapidly exploring these spaces as users perform collaborative work in an extended reality environment.The proposed system provides methods for arranging and manipulating remote and personal spaces by creating an annular screen that is invisible to the user.The user can freely arrange remote participants and their workspaces on the annular screen.Because users can simultaneously view various spaces arranged on the annular screen,they can perform collaborative work while simultaneously feeling the presence of multiple spaces and can be fully immersed in a specific space.In addition,the personal spaces where users work can also be arranged through the annular screen.According to the results of the performance evaluations,users participating in remote collaborative works can visualize the spaces of multiple users simultaneously and feel their presence,thereby increasing their understanding of the spaces.Moreover,the proposed system reduces the time to perform tasks and gain awareness of the emergency in remote workspaces.

Investigating the components of fintech ecosystem for distributed energy investments with an integrated quantum spherical decision support system

This study aimed to evaluate the components of a fintech ecosystem for distributed energy investments.A new decision-making model was created using multiple stepwise weight assessment ratio analysis and elimination and choice translating reality techniques based on quantum spherical fuzzy sets.First,in this model,the criteria for distributed energy investment necessities were weighted.Second,we ranked the components of the fintech ecosystem for distributed energy investments.The main contribution of this study is that appropriate strategies can be presented to design effective fintech ecosystems to increase distributed energy investments,by considering an original fuzzy decision-making model.Capacity is the most critical issue with respect to distributed energy investment necessities because it has the greatest weight(0.261).Pricing is another significant factor for this condition,with a weight of 0.254.Results of the ranking of the components of the fintech ecosystem indicate that end users are of the greatest importance for the effectiveness of this system.It is necessary to develop new techniques for the energy storage process,especially with technological developments,to prevent disruptions in energy production capacity.In addition,customers’expectations should be considered for the development of effective and user-friendly financial products that are preferred by a wider audience.This would have a positive effect on fintech ecosystem performance.

Hybrid Optimization Based PID Controller Design for Unstable System

PID controllers play an important function in determining tuning para-meters in any process sector to deliver optimal and resilient performance for non-linear,stable and unstable processes.The effectiveness of the presented hybrid metaheuristic algorithms for a class of time-delayed unstable systems is described in this study when applicable to the problems of PID controller and Smith PID controller.The Direct Multi Search(DMS)algorithm is utilised in this research to combine the local search ability of global heuristic algorithms to tune a PID controller for a time-delayed unstable process model.A Metaheuristics Algorithm such as,SA(Simulated Annealing),MBBO(Modified Biogeography Based Opti-mization),BBO(Biogeography Based Optimization),PBIL(Population Based Incremental Learning),ES(Evolution Strategy),StudGA(Stud Genetic Algo-rithms),PSO(Particle Swarm Optimization),StudGA(Stud Genetic Algorithms),ES(Evolution Strategy),PSO(Particle Swarm Optimization)and ACO(Ant Col-ony Optimization)are used to tune the PID controller and Smith predictor design.The effectiveness of the suggested algorithms DMS-SA,DMS-BBO,DMS-MBBO,DMS-PBIL,DMS-StudGA,DMS-ES,DMS-ACO,and DMS-PSO for a class of dead-time structures employing PID controller and Smith predictor design controllers is illustrated using unit step set point response.When compared to other optimizations,the suggested hybrid metaheuristics approach improves the time response analysis when extended to the problem of smith predictor and PID controller designed tuning.

Selection of Wind Turbine Systems for the Sultanate of Oman

The Sultanate of Oman has been dealing with a severe renewable energy issue for the past few decades,and the government has struggled to find a solution.In addition,Oman’s strategy for converting power generation to sources of renewable energy includes a goal of 60 percent of national energy demands being met by renewables by 2040,including solar and wind turbines.Furthermore,the use of small-scale energy from wind devices has been on the rise in recent years.This upward trend is attributed to advancements in wind turbine technology,which have lowered the cost of energy from wind.To calculate the internal and external factors that affect the small-scale energy of wind technologies,the study used a fuzzy analytical hierarchy process technique for order of preference by similarity to an ideal solution.As a result,in the decision model,four criteria,seventeen sub-criteria,and three resources of renewable energy were calculated as options from the viewpoint of the Sultanate of Oman.This research is based on an examination of statistics on energy produced by wind turbines at various locations in the Sultanate of Oman.Further,six distinct miniature wind turbines were investigated for four different locations.The outcomes of this study indicate that the tiny wind turbine has a lot of potential in the Sultanate of Oman for applications such as homes,schools,college campuses,irrigation,greenhouses,communities,and small businesses.The government should also use renewable energy resources to help with the renewable energy issue and make sure that the country has enough renewable energy for its long-term growth.

藏南拆离系活动与淡色花岗岩就位——以希夏邦马峰地区为例

藏南拆离系是世界上最大的拆离断层系统,也是喜马拉雅造山带的重要构造边界,对喜马拉雅造山过程起着重要的控制作用。在拆离断层内部和断层下盘的高喜马拉雅单元,出露了大量的同构造淡色花岗岩;近期研究工作发现,这些淡色花岗岩具有良好的稀有金属成矿潜力,因此,研究藏南拆离系的活动历史和淡色花岗岩的就位过程,对理解拆离断层变形和演化过程、熔体-断层相互作用和成矿有着重要的启示意义。针对该问题,本文选择喜马拉雅造山带中段希夏邦马峰附近的两条经典剖面——吉隆和聂拉木,开展系统的构造地质学研究,就藏南拆离系的演化过程和淡色花岗岩的同构造迁移-就位机制进行初步探讨。研究表明,吉隆地区的拆离断层厚度数十米到上百米,影响范围小,下盘吉隆岩体和高喜马拉雅的向北拆离变形较弱;聂拉木拆离断层为藏南拆离系深部构造层次,拆离断层厚度达数千米,强烈的构造变形导致肉切村群和高喜马拉雅顶部发生强烈的糜棱岩化,韧性剪切后的淡色花岗岩以平行拆离断层的岩席或岩脉产出;由此,我们认为吉隆和聂拉木的拆离断层分别代表了藏南拆离系的不同构造层次,受控于后期不均一的构造隆升剥露过程,进而可以解释两个地区不同的构造特征。综合前人的研究工作,我们提出藏南拆离系内部拆离断层活动存在逐渐向上迁移现象,而淡色花岗岩的侵位对该过程有着重要的促进作用。早期藏南拆离系的主拆离断层层次较深,控制了淡色花岗岩的顺层迁移和就位;而晚期熔体向更浅层次的运移,也促使藏南拆离系的主拆离断层也向上部迁移。

希夏邦马峰淡色花岗岩岩石成因初步研究

淡色花岗岩是研究碰撞造山带地球动力学过程的重要对象。本文对喜马拉雅造山带希夏邦马峰海拔5800m大本营附近的淡色花岗岩样品进行了独居石U-Th-Pb年代学和全岩地球化学初步分析。研究样品根据矿物组合可分为黑云母花岗岩和二云母花岗岩,二者地球化学特征以及变形程度都有所差异,全岩地球化学中弱变形的黑花岗岩表现出低Si和富Al、Mg、Fe、K、Ti的特征,铝饱和指数A/CNK为1.06;强变形和弱变形的二云母花岗岩均表现出高Si和贫Mg、Fe、K、Ti的特征,A/CNK为1.11~1.17。同黑云母花岗岩相比,二云母花岗岩稀土元素中Eu元素负异常明显,微量元素中富集Sn、U,亏损Ba、Sr、Zr、Hf、LREE等元素,暗示岩浆经历了斜长石、黑云母、锆石、独居石和磷灰石的分离结晶作用。黑云母花岗岩和二云母花岗岩中的独居石给出U-Th-Pb年龄为22.9±0.2Ma、22.7±0.5Ma和22.7±0.7Ma的一致结果,这一年龄略早于前人报道的结果,指示藏南拆离系活动时间在该区域与喜马拉雅中段具有一致性。本文认为希夏邦马淡色花岗岩岩浆作用与碰撞后伸展阶段发育的藏南拆离系活动具有同时性。

近断层地震动引起的公路桥梁车桥分离现象的统计分析

近年来,随着我国人均汽车保有量的增加,国内交通密度增大,交通拥堵加剧,再加上重卡超载现象越来越严重,机动车辆荷载对中小跨径桥梁的影响显著增大,也提高了地震发生时桥上有车的概率;另一方面,近断层地震动具有显著的竖向效应,已有震害表明车辆与桥梁在较强的竖向地震动作用下容易产生车桥分离或碰撞的现象。因此,考虑近断层地震动作用下车辆对桥梁动力响应的影响将有助于准确评估桥梁的抗震性能。文章以一座典型的3跨连续梁桥为工程背景,采用考虑车辆与桥面动态接触或分离的模型对实际近断层地震动作用下的车桥耦合系统的动力响应进行统计分析,研究车辆对桥梁的动力放大作用、车桥分离现象及其影响规律。结果表明,在车桥不分离的情况下,考虑车辆影响在80%的工况下会减小桥梁的竖向位移响应,但随着竖向PGA的增大,车辆对桥梁的动力作用逐渐趋于不利;其次,车桥之间的动力相互作用可能导致不止一次的车桥分离,最大接触力在大多数情况下发生在首次分离与二次分离之间,最大可能达到车辆重量的7.9倍,会对桥面局部受力产生极其不利的影响,且车桥分离的时间随着车辆竖向频率的增大而增加,但这种现象与地震动的竖向PGA没有直接关系,对桥梁的竖向位移响应影响也不大。

目的探讨近视患者视网膜脱离的危险因素及风险预测模型。方法回顾性分析2021年1月至2023年12月于我院就诊的近视患者的临床资料,选择符合条件的近视性视网膜脱离患者128例(128眼)作为视网膜脱离组,没有视网膜脱离的近视患者128例(128眼)作为对照组。收集两组患者的临床资料,包括年龄、性别、屈光度、文化程度、病侧、是否负重、有无震动、有无白内障、是否存在视疲劳、血压、糖尿病史、眼外伤史、眼科手术史、视网膜厚度等。采用多因素Logistic回归分析确定近视性视网膜脱离的危险因素,并据以建立多因素联合应用的风险预测模型,应用受试者工作特征曲线(ROC)进行预测评估价值分析。结果视网膜脱离组患者的年龄、屈光度、收缩压、白内障发生率、视疲劳发生率、眼外伤发生率以及眼科手术史率均显著高于对照组(均为P<0.05);视网膜脱离组患者的视网膜厚度与脉络膜厚度均显著低于对照组(均为P<0.05)。近视患者发生视网膜脱离的危险因素为年龄(较大),屈光度(绝对值较大),伴有白内障或视疲劳或眼外伤等眼部疾患或不适状况,脉络膜厚度(较小),视网膜厚度(较小)(均为OR>1,P<0.05)。年龄、眼部疾患或不适、屈光度、脉络膜厚度、视网膜厚度等5项指标单独及联合应用时ROC曲线下面积(AUC)(0.95 CI)分别为0.668(0.382~0.936)、0.645、0.676(0.407~0.942)、0.731(0.503~0.933)、0.745(0.499~0.983)、0.844(0.692~0.983),联合应用预测评估效能更高,AUC(0.844)及灵敏度、特异度、准确度均较单独应用指标有明显提升。结论近视患者发生视网膜脱离的危险因素为较大的年龄,较大的屈光度(绝对值),伴有包括白内障、视疲劳、眼外伤在内的眼部疾患或不适,较小的脉络膜厚度、较小的视网膜厚度。由这些因素构建的风险预测模型评估效能较高。

基于DDES耦合FW-H方法的吊舱推进器水动力噪声特性

为研究吊舱推进器非定常流场和诱发的声场结构,采用DDES耦合FW-H方法,对其开展了高精度非定常数值计算.结果表明:由于吊柱诱发的强烈动静干涉作用,使螺旋桨至吊柱区域内的压力脉动幅值上升;吊舱推进器的涡量分布较为复杂,由于吊舱体的扰流作用,除螺旋桨本身产生的主、副涡外,还出现干涉尾涡结构,且主涡区向上偏移.通过计算盘面上各个声接收点处的谐波频率标准差发现,声场在浆盘面上无明显声指向性.通过设置空间曲面内的声接收点阵列,获得了吊舱推进器的声场空间分布特性.发现轴频和叶频始终是其主要频率;在螺旋桨桨盘面附近的声压脉动无明显指向性,但在空间曲面上,轴频和叶频的分布特征明显,存在有明显形状的高低值区;在吊舱推进器后方,声压逐渐衰减,但叶频处能量衰减趋势小于轴频处.

Evaluation of Linear Precoding Schemes for Cooperative Multi-Cell MU MIMO in Future Mobile Communication Systems

In Mobile Communication Systems, inter-cell interference becomes one of the challenges that degrade the system’s performance, especially in the region with massive mobile users. The linear precoding schemes were proposed to mitigate interferences between the base stations (inter-cell). These schemes are categorized into linear and non-linear;this study focused on linear precoding schemes, which are grounded into three types, namely Zero Forcing (ZF), Block Diagonalization (BD), and Signal Leakage Noise Ratio (SLNR). The study included the Cooperative Multi-cell Multi Input Multi Output (MIMO) System, whereby each Base Station serves more than one mobile station and all Base Stations on the system are assisted by each other by shared the Channel State Information (CSI). Based on the Multi-Cell Multiuser MIMO system, each Base Station on the cell is intended to maximize the data transmission rate by its mobile users by increasing the Signal Interference to Noise Ratio after the interference has been mitigated due to the usefully of linear precoding schemes on the transmitter. Moreover, these schemes used different approaches to mitigate interference. This study mainly concentrates on evaluating the performance of these schemes through the channel distribution models such as Ray-leigh and Rician included in the presence of noise errors. The results show that the SLNR scheme outperforms ZF and BD schemes overall scenario. This implied that when the value of SNR increased the performance of SLNR increased by 21.4% and 45.7% for ZF and BD respectively.

基于知识图谱多跳推理的中文矿物知识问答方法与系统

已有相关矿物数据库用于存储和查询相关矿物知识,常用的搜索引擎也可以对矿物知识进行查询,但无法回答用自然语言进行提问的矿物问题,查询返回的答案需要进一步筛选。亦有基于知识图谱进行矿物知识问答的相关研究,但只能回答涉及知识图谱中一个三元组的简单问题,无法回答涉及多个三元组的多跳复杂问题。为此,本文提出基于知识图谱多跳推理的矿物复杂知识问答方法,采用ComplEx模型将矿物实体、关系和问句表示为复数向量,以更好地获取相互之间的语义及推理关系。输入矿物问句后,通过Bert-LSTM-CRF获取其中心词,采用基于编辑距离及分词的方法获得中心词的候选实体集合,然后采用全连接网络确定最相关的实体作为推理起点,与矿物问句拼接后通过全连接网络获得当前跳的最相关关系。根据当前跳的起始实体及最相关关系,在矿物知识图谱中获得另一实体作为下一跳的推理起点,并将下一跳的问句更新为原问句,与当前跳最相关关系拼接,以将当前跳的推理信息带入到下一跳推理中,直到获得的最相关推理关系为预定义的结束标识符,推理结束,返回最后一跳的实体为答案,并给出推理路径。采用Python语言,在Tensorflow框架下实现了本文提出的矿物复杂知识问答并与相关模型进行对比,证明了本文方法的有效性。采用前后端分离架构,使用RESTful API、React、Ajax、echarts和Flask等框架和技术,开发了基于知识图谱多跳推理的矿物复杂知识问答系统,为矿物知识获取及相关地质研究提供了平台和工具。
