| 1 | A comparative analysis among computational intelligence techniques for dissolved oxygen prediction in Delaware River显示文摘Most of the water quality models previously developed and used in dissolved oxygen(DO) prediction are complex.Moreover,reliable data available to develop/calibrate new DO models is scarce.Therefore,there is a need to study and develop models that can handle easily measurable parameters of a particular site,even with short length.In recent decades,computational intelligence techniques,as effective approaches for predicting complicated and significant indicator of the state of aquatic ecosystems such as DO,have created a great change in predictions.In this study,three different Al methods comprising:(1) two types of artificial neural networks(ANN) namely multi linear perceptron(MLP) and radial based function(RBF);(2) an advancement of genetic programming namely linear genetic programming(LGP);and(3) a support vector machine(SVM) technique were used for DO prediction in Delaware River located at Trenton,USA.For evaluating the performance of the proposed models,root mean square error(RMSE),Nash-Sutcliffe efficiency coefficient(NS),mean absolute relative error(MARE) and,correlation coefficient statistics(R) were used to choose the best predictive model.The comparison of estimation accuracies of various intelligence models illustrated that the SVM was able to develop the most accurate model in DO estimation in comparison to other models.Also,it was found that the LGP model performs better than the both ANNs models.For example,the determination coefficient was 0.99 for the best SVM model,while it was 0.96,0.91 and 0.81 for the best LGP,MLP and RBF models,respectively.In general,the results indicated that an SVM model could be employed satisfactorily in DO estimation. | Ehsan Olyaie Hamid Zare Abyaneh Ali Danandeh Mehr | 2017 | Geoscience Frontiers2017,8,3: | 11 |
| 2 | One-step synthesis of N-doped metal/biochar composite using NH_3-ambiance pyrolysis for efficient degradation and mineralization of Methylene Blue显示文摘A series of new biochar-supported composite based on the combination of biochar and metallic nanoparticles(NPs)were produced through single-step pyrolysis of FeCl_3–Ti(OBu)_4 laden agar biomass under NH_3 environment.The physiochemical properties of composites were characterized thoroughly.It has found that heating temperature and N-doping through NH_3-ambiance pyrolysis significantly influence the visible-light sensitivity and bandgap energy of composites.The catalytic activities of composites were measured by degradation of Methylene Blue(MB)in the presence or absence of H_2O_2 and visible-light irradiation.Our best catalyst(N–TiO_2–Fe_3O_4-biochar)exhibits rapid and high MB removal competency(99.99%)via synergism of adsorption,photodegradation,and Fenton-like reaction.Continuous production of O_2U^-and UOH radicles performs MB degradation and mineralization,confirmed by scavenging experiments and degradation product analysis.The local trap state Ti^(3+),Fe_3O_4,and N-carbon of the catalyst acted as active sites.It has suggested that the Ti^(3+)and N-doped dense carbon layer improve charge separation and shuttle that prolonged photo-Fenton like reaction.Moreover,the catalyst is highly stable,collectible,and recyclable up to 5 cycles with high MB degradation efficiency.This work provides a new insight into the synthesis of highly visible-light sensitized biocharsupported photocatalyst through NH_3-ambiance pyrolysis of NPs-laden biomass. | Md Manik Mian Guijian Liu Balal Yousaf Biao Fu Rafay Ahmed Qumber Abbas Mehr Ahmed Mujtaba Munir Liu Ruijia | 2019 | Journal of Environmental Sciences2019,31,4: | 8 |
| 3 | Multigene genetic programming for sediment transport modeling in sewers for conditions of non-deposition with a bed deposit显示文摘It is known that construction of large sewers based on consideration of flow with non-deposition without a bed deposit is not economical. Sewer design based on consideration of flow with nondeposition with a bed deposit reduces channel bed slope and construction cost in which the presence of a small depth of sediment deposition on the bed increases the sediment transport capacity of the flow.This paper suggests a new Pareto-optimal model developed by the multigene genetic programming(MGGP) technique to estimate particle Froude number(Frp) in large sewers with conditions of sediment deposition on the bed. To this end, four data sets including wide ranges of sediment size and concentration, deposit thickness, and pipe size are used. On the basis of different statistical performance indices, the efficiency of the proposed Pareto-optimal MGGP model is compared to those of the best MGGP model developed in the current study as well as the conventional regression models available in the literature. The results indicate the higher efficiency of the MGGP-based models for Frp estimation in the case of no additional deposition onto a bed with a sediment deposit. Inasmuch as the Pareto-optimal MGGP model utilizes a lower number of input parameters to yield comparatively higher performance than the conventional regression models, it can be used as a parsimonious model for self-cleansing design of large sewers in practice. | Mir Jafar Sadegh Safari Ali Danandeh Mehr | 2018 | International Journal of Sediment Research2018,33,3: | 3 |
| 4 | Effectiveness and time-course adaptation of resistance training vs. plyometric training in prepubertal soccer players显示文摘Purpose:This study aimed to assess the effectiveness and time course for improvements in explosive actions through resistance training(RT)vs.plyometric training(PT)in prepubertal soccer players.Methods:Thirty-four male subjects were assigned to:a control group(n=11);an RT group(5 regular soccer training sessions per week,n=12);a PT group(3 soccer training sessions and 2 RT sessions per week,n=11).The outcome measures included tests for the assessment of muscle strength(e.g.,1 repetition maximum half-squat test),jump ability(e.g.,countermovement jump,squat jump,standing long jump,and multiple 5 bounds test),linear speed(e.g.,20m sprint test),and change of direction(e.g.,Illinois change of direction test).Results:The RTG showed an improvement in the half-squat(△=13.2%;d=1.3,p<0.001)and countermovement jump(△=9.4%;d=2.4,p<0.001)at Week 4,whereas improvements in the 20-m sprint(△=4.2%;d=1.1,p<0.01);change of direction(CoD)(△=3.8%;d=2.1,p<0.01);multiple 5 bounds(△=5.1%;d=1.5,p<0.05);standing long jump(△=7.2%;d=1.2,p<0.01);squat jump(△=19.6%;d=1.5,p<0.01);were evident at Week 8.The PTG showed improvements in CoD(△=2.1%;d=1.3,p<0.05);standing long jump(△=9.3%;d=1.1,p<0.01);countermovement jump(△=16.1%;d=1.2,p<0.01);and squat jump(△=16.7%;d=1.4,p<0.01);at Week 8 whereas improvements in the 20-m sprint(△=4.1%;d=1.3,p<0.01);and multiple 5 bounds(△=7.4%;d=2.4,p<0.001);were evident only after Week.The RT and PT groups showed improvements in all sprint,CoD,and jump tests(p<0.05)and in half-squat performance,for which improvement was only shown within the RTG(p<0.001).Conclusion:RT and PT conducted in combination with regular soccer training are safe and feasible interventions for prepubertal soccer players.In addition,these interventions were shown to be effective training tools to improve explosive actions with different time courses of improvements,which manifested earlier in the RTG than in the PTG.These outcomes may help coaches and fitness trainers set out clear and concise goals of training according to the specific time course of improvement difference between RT and PT on proxies of athletic performance of prepubertal soccer players. | Yassine Negra Helmi Chaabene Thomas Stöggl Mehréz Hammami Mohamed Souhaiel Chelly Younés Hachana | 2020 | Journal of Sport and Health Science2020,9,6: | 3 |
| 5 | Combination of sensitivity and uncertainty analyses for sediment transport modeling in sewer pipes显示文摘Mitigation of sediment deposition in lined open channels is an essential issue in hydraulic engineering practice.Hence,the limiting velocity should be determined to keep the channel bottom clean from sediment deposits.Recently,sediment transport modeling using various artificial intelligence(AI)techniques has attracted the interest of many researchers.The current integrated study highlights unique insight for modeling of sediment transport in sewer and urban drainage systems.A novel methodology based on the combination of sensitivity and uncertainty analyses with a machine learning technique is proposed as a tool for selection of the best input combination for modeling process at non-deposition conditions of sediment transport.Utilizing one to seven dimensionless parameters,127 models are developed in the current study.In order to evaluate the different parameter combinations and select the training and testing data,four strategies are considered.Considering the densimetric Froude number(Fr)as the dependent parameter,a model with independent parameters of volumetric sediment concentration(CV)and relative particle size(d/R)gave the best results with a mean absolute relative error(MARE)of 0.1 and a root means square error(RMSE)of 0.67.Uncertainty analysis is applied with a machine learning technique to investigate the credibility of the proposed methods.The percentage of the observed sample data bracketed by 95%predicted uncertainty bound(95PPU)is computed to assess the uncertainty of the best models. | Isa Ebtehaj Hossein Bonakdari Mir Jafar Sadegh Safari Bahram Gharabaghi Amir Hossein Zaji Hossien Riahi Madavar Zohreh Sheikh Khozani Mohammad Sadegh Es-haghi Aydin Shishegaran Ali Danandeh Mehr | 2020 | International Journal of Sediment Research2020,35,2: | 2 |
| 6 | 食物蛋白诱导性小肠结肠炎综合征:一项基于澳大利
亚普通人群的研究,2012-2014显示文摘背景 食物蛋白诱导性小肠结肠炎综合征(FPIES)是一种非IgE 介导的胃肠道过敏性疾病。基于大规模人群的FPIES 流行病学调查尚无报道。目的 本文拟明确澳大利亚婴幼儿中FPIES 的发病率和临床特点。方法 2012 至2014年通过澳大利亚儿科监测体系开展了一项全国范围内的调查,由1 400 名儿科医生每月上报2 岁以下的婴幼儿中诊为急性FPIES 的新病例。结果 230 例患儿被诊为FPIES。FPIES 在澳大利亚2 岁以下儿童中的发病率为15.4/(10 万·年)。首次发作、诊断及上报的中位数年龄分别为5、7 和10 月龄。发病没有性别倾向性。7% 的患儿有兄弟姐妹也患有FPIES,5% 在纯母乳喂养期间发病。68 例患儿仅对单种食物过敏(20% 对2 种食物过敏,12% 对3 种以上食物过敏)。最常见的FPIES 诱因是大米(45%)、牛奶(33%)以及鸡蛋(12%)。51% 的患儿在首次暴露时即有过敏反应。与单种食物过敏相比,多种食物过敏者的首次发病年龄更小(均数分别为4.6 和5.8 月龄,P = 0.001),更容易有水果或蔬菜过敏(P < 0.000 1)。纯母乳喂养4 个月以上的婴儿更不易发生多种食物过敏性FPIES(P = 0.06)。对包括牛奶在内的多种食物过敏的FPIES 患儿中64% 同时对固体食物过敏。42% 鱼类过敏性FPIES 患儿并发其他食物过敏。结论 FPIES并不罕见,估计发病率为15.4/(10 万·年)。大米是澳大利亚最常见的食物诱因。与多重食物过敏性FPIES 相关的危
险因素包括早期起病、对水果或蔬菜不能耐受。 | Sam Mehr FRACP, Katie Frith FRACP Elizabeth H. Barnes BAppSc MStat and Dianne E Campbell | 2018 | 中华临床免疫和变态反应杂志2018,12,1: | 2 |
| 7 | 食物过敏治疗显示文摘IgE 介导的食物过敏患病率在全世界范围内呈升高趋势,已成为困扰数以百万计患者的公共健康问题。但目前的标准治疗方案仅为严格禁食过敏食物及含过敏食物成分的食品,尚无已经审批认证的食物过敏治疗方法。目前已有大量的有关不同形式食物免疫治疗的研究,包括口服、舌下及经皮给药途径。尽管口服免疫治疗因蛋白摄入量最大而疗效最肯定,但与舌下免疫治疗及经皮免疫治疗相比耐受性较差,不良反应重,发生率也较高。经皮免疫治疗虽然疗效相对最弱,但安全性及耐受性最佳。很多研究通过尝试添加佐剂和anti-IgE 提高食物免疫治疗的疗效及安全性。此外还有许多超前于这些第一代食物免疫治疗方法的新概念疗法尚处于动物试验或早期I 期临床试验阶段。 | Sam Mehr Katie Frith Elizabeth H.Barnes BAppSc MStat Dianne E.Campbell 王子熹 王良录 | 2018 | 中华临床免疫和变态反应杂志2018,12,1: | 2 |
