1基于卷积神经网络的田间多簇猕猴桃图像识别方法显示文摘为实现田间条件下快速、准确地识别多簇猕猴桃果实,该文根据猕猴桃的棚架式栽培模式,采用竖直向上获取果实图像的拍摄方式,提出一种基于Le Net卷积神经网络的深度学习模型进行多簇猕猴桃果实图像的识别方法。该文构建的卷积神经网络通过批量归一化方法,以Re LU为激活函数,Max-pooling为下采样方法,并采用Softmax回归分类器,对卷积神经网络结构进行优化。通过对100幅田间多簇猕猴桃图像的识别,试验结果表明:该识别方法对遮挡果实、重叠果实、相邻果实和独立果实的识别率分别为78.97%、83.11%、91.01%和94.78%。通过与5种现有算法进行对比试验,该文算法相对相同环境下的识别方法提高了5.73个百分点,且识别速度达到了0.27 s/个,识别速度较其他算法速度最快。证明了该文算法对田间猕猴桃图像具有较高的识别率和实时性,表明卷积神经网络在田间果实识别方面具有良好的应用前景。傅隆生 冯亚利 Elkamil Tola 刘智豪 李瑞 崔永杰 2018农业工程学报2018,34,2:98
2Etiology and portal vein thrombosis in Budd-Chiari syndrome显示文摘AIM: To research the etiology, portal vein thrombosis and other features of Budd-Chiari syndrome (BCS) patients prospectively. METHODS: A total of 75 patients (40 female, 35 male) who were diagnosed between January 2002 and July 2004 as having BCS were studied prospectively. Findings from on physical examination, ultrasonography, duplex ultrasonography and venography were analyzed. Hemogram and blood chemistry were studied at the time of diagnosis and on each hospital visit. Bone marrow examination and immune phenotyping were performed by a hematologist when necessary. Protein C, S, antithrombin Ⅲ, activated protein C resistance, and anticardiolipin antibodies, antinuclear antibodies, and anti ds-DNA were studied twice. The presence of ascite, esophageal varices, and portal thrombosis were evaluated at admission and on every visit. RESULTS: At least one etiological factor was determined in 54 (72%) of the patients. The etiology could not be defined in 21 (28%) patients. One etiological factor was found in 39, 2 factors in 14 and 3 factors in 1 patient. The most common cause was the web (16%), the second was Hydatid disease (11%), the third was Behcet’s disease (9%). Portal vein thrombosis was present in 11 patients and at least one etiology was identified in 9 of them (82%). CONCLUSION: Behcet’s disease and hydatid disease are more prominent etiological factors in Turkey than in other countries. Patients with web have an excellent response to treatment without signs of portal veinthrombosis while patients having thrombofilic factors more than one are prone to develop portal vein thrombosis with worse clinical outcome.Oguz Uskudar Meral Akdogan Nurgul Sasmaz Sevinc Yilmaz Muharrem Tola Burhan Sahin 2008World Journal of Gastroenterology2008,14,18:14
3基于高速摄影的冬枣果实振动脱落规律分析显示文摘为研究冬枣振动采收过程中果实的运动规律和脱落轨迹,采用改装的电动往复锯连接自制振动采摘头对树枝进行高速振动,用高速相机记录不同振动频率(15、20、25 Hz)下冬枣果实的运动轨迹,对高速视频进行分析,计算在振动过程中的枣果脱落类型、脱落时间和运动轨迹,以及果实脱落时的速度、加速度和惯性力。结果表明:1)冬枣果实的主要脱落类型是旋倾型,15、20和25Hz时,旋倾型脱落的果实个数比例分别为81%、66%和78%,参考已有研究经验,冬枣机械收获宜选用连续式振动设备;2)随着振动频率的增大,果实的平均脱落时间减小,3个频率的果实脱落时间分别为1.71、0.54和0.43s,15Hz时果实脱落时间与20和25Hz时的果实脱落时间存在显著性差异,而20与25Hz时的果实脱落时间无显著性差异;3)果实的速度和加速度随着振动频率的增大而增大,但不同频率的果实平均脱落惯性力不存在显著性差异,3个频率下分别为0.48、0.43和0.49N。本研究结果可为机械收获装备的设计选型与研发提供理论依据。傅隆生 刘智豪 冯亚利 谢洪起 彭俊 ELKAMIL Tola YAQOOB Majeed 崔永杰 2018中国农业大学学报2018,23,8:5
4Effects of sociodemographic characteristics and patients’health beliefs on tuberculosis treatment adherence in Ethiopia:a structural equation modelling approach显示文摘Background:Patients’beliefs are a major factor affecting tuberculosis(TB)treatment adherence.However,there has been little use of Health Belief Model(HBM)in determining the pathway effect of patients’sociodemographic characteristics and beliefs on TB treatment adherence.Therefore,this study was aimed at determining the effect of sociodemographic characteristics and patients’health beliefs on TB treatment adherence based on the HBM concept in Ethiopia.Methods:A cross-sectional study was conducted in Addis Ababa,Ethiopia among TB patients undertaking treatment.Thirty health centres were randomly selected and one hospital was purposely chosen.Six hundred and ninety-eight TB patients who had been on treatment for 1-2 month,were aged 18 years or above,and had the mental capability to provide consent were enrolled consecutively with non-probability sampling technique from the TB registration book until required sample size achieved.Structured questionnaires were used to collect data.Structural equation modelling was employed to assess the pathway relationship between sociodemographic characteristics,patients’beliefs,and treatment adherence.Results:Of the 698 enrolled participants,401(57.4%)were male and 490(70.2%)were aged 35 years and below.The mean age of participants was 32(±11.7)and the age range was 18-90 years.Perceived barrier/benefit was shown to be a significant direct negative effect on TB treatment adherence(ß=−0.124,P=0.032).In addition,cue to action(ß=−0.68,P≤0.001)and psychological distress(ß=0.08,P<0.001)were shown significant indirect effects on TB treatment adherence through perceived barrier/benefit.Conclusions:Interventions intended to decrease perceived barriers and maximize perceived benefits should be implemented to enhance TB treatment adherence.In addition,it is crucial that counselling is incorporated with the regular directly observed therapy program.Motivators(cue to actions)such as friends,family,healthcare workers,and the media could be used to promote TB treatment adherence.Habteyes Hailu Tola Mehrdad Karimi Mir Saeed Yekaninejad 2017Infectious Diseases of Poverty2017,6,1:3

6Impacts of center pivot irrigation system uniformity on growth of potato crop and residual soil nitrogen显示文摘Maintaining the homogeneity of soil nitrogen(N)and plant vigor across agricultural fields is a major concern for farmers and agricultural scheme planners,particularly fields that are irrigated through pressurized systems,such as center pivots.Therefore,this study was carried out on a 30 hm2 potato field located 650 km south of Riyadh,the capital city of the Kingdom of Saudi Arabia,to investigate the impacts of the center pivot irrigation distribution uniformity on the crop development and the spatial distribution of residual soil N.Irrigation performance test was designed to investigate water application rate and distribution uniformities.The overall water application uniformity coefficients(Cu),determined through Christiansen(Cud)and Heerman(CuH)methods,were determined at 81.29%and 80.64%,respectively.However,the overall water distribution uniformity(Du)was determined at 70%.A considerable variability in the distribution uniformity of irrigation water was observed across the experimental field(a Du value of 67%over the medium spans compared to a Du value of 88%over the inner spans).Results of this study showed a linear correlation between the irrigation water distribution uniformity and the soil N(R^(2)=0.88).On the other hand,the vegetation cover distribution,indicated by the Cumulative Normalized Difference Vegetation Index(CNDVI),was not found to be much responsive to the irrigation distribution uniformity(R^(2)=0.11).A time series of successive NDVI maps extracted throughout the potato crop growth stages showed a consistent trend in the distribution of NDVI across the field,with R2 values that ranged between 0.25-0.73.Khalid A.Al-Gaadi Abdalhaleem A.Hassaballa ElKamil Tola Ahmed G.Kayad Rangaswamy Madugundu Fahad Assiri Mohamed Edrris Ahmed Alameen Haroon Edrees 2019International Journal of Agricultural and Biological Engineering2019,12,1:2
