| 1 | 甘肃河东玉米种植区春夏气象干旱时空变化特征及其与环流因子关系显示文摘甘肃河东玉米种植区属于旱作雨养农业区,农作物生长主要依靠自然降水来维持,春夏干旱是影响该区玉米生长发育的关键因素。利用河东地区13个气象站点1957—2012年气象资料,基于标准化降水蒸散指数从干旱趋势、周期、空间特征及其与环流因子关系方面探讨近56 a来河东玉米种植区春夏干旱演变特征。结果表明:近56 a河东玉米种植区春夏两季均呈干旱化趋势,并自20世纪90年代中期以后,干旱呈加重趋势。干旱变化共经历了3个气候阶段,20世纪80年代之前,春夏旱情较轻;80年代—90年代,夏旱较春旱严重;2000年以后,春旱较夏旱严重。干旱周期变化,春夏干旱周期分别为20 a和14 a,干旱周期性变化主要是受太阳黑子活动影响。春夏干旱发生频率在突变前后差异显著,低频区在突变后转为高频区,易旱区呈扩大状态。ENSO事件是影响该区春夏干旱发生的主要环流因子,尤其对夏旱影响最为显著。近20 a来ENSO事件增强是该区干旱事件不断加重的原因,ENSO暖事件爆发时,该区春夏趋于干旱,由湿向干转变;ENSO冷事件爆发,干旱则有所缓解,由干向湿转变。 | 季定民 张勃 王东 马琼 张耀宗 赵一飞 Yousif Elnour Yagoub | 2015 | 自然资源学报2015，30，9： | 17 |
| 2 | 交直流混合电网的多智能体自律分散控制显示文摘针对交直流混合电网传统集中控制缺乏灵活性和鲁棒性的特点,以及分布式控制无法同时兼顾全局最优及响应速度等的不足,提出一种基于多智能体系统的交直流混合电网自律分散控制策略,即在多端直流的每个端子都设置一个智能体,构成多智能体系统,每个智能体都包含两个功能模块:全局信息获取模块和自主决策模块。采用这种控制策略时,上层优化问题与传统的电网调度问题相近,下层系统通过智能体之间以及智能体与系统间的交互、协调,实现群体妥协解。在仅有邻居换流站电压、频率等状态信息基础上,基于多智能体一致性控制实现各端换流站间有功功率的合理分配,平抑负荷波动。最后通过PSCAD仿真搭建典型的交直流混合电网验证所提控制策略的有效性及优越性。 | 高扬 艾芊 郝然 张昭丞 Muhammad Yousif | 2017 | 电网技术2017，41，4： | 15 |

| 4 | Safety and efficacy of ultrasound ciliary plasty as a primary intervention in glaucoma patients显示文摘AIM: To evaluate the safety and the efficacy of the ultrasound ciliary plasty(UCP) on the intraocular pressure(IOP) control in glaucomatous eyes without previous glaucoma surgery.METHODS: A retrospective study included patients with primary and secondary glaucoma who underwent UCP in Dar Al Shifa Hospital, Kuwait between January 2017 to June 2018. High-intensity focused ultrasound procedures were performed under peribulbar anesthesia using the 2^(nd) generation probe with 8 s duration of each of the 6 shots. Complete ophthalmologic examinations were scheduled pre-treatment, and at 1 d, 1 wk, 1, 3, 6 and 12 mo posttreatment. Primary outcomes were the IOP reduction and success rates at 12 mo, while the secondary outcomes were the occurrence of vision threatening complications and visual acuity.RESULTS: The records of 62 eyes of 62 patients were analyzed with mean age of 63.8 y(67.7% males). There was statistically significant reduction in the mean IOP from 35.2±8.3 mm Hg before treatment to 20.6±8.7 mm Hg at 12^(th) month(P<0.0005) with a mean percentage IOP reduction of 42.3% with significant reduction in the mean number of antiglaucomatous drugs from 3.2±0.4 before treatment to 2.1±1.02 at 12 mo(P<0.0005). Qualified success was achieved in 77.4% of eyes at 12 mo. No major intra-or posttreatment complications were reported.CONCLUSION: Second-generation UCP prove to be effective in reducing IOP in naive glaucoma patients with lower success rates in cases of neovascular and uveitic glaucomas. | Magda A.Torky Yousif A Al Zafiri Sherein M.Hagras Abeer M.Khattab Rania M.Bassiouny Tharwat H.Mokbel | 2019 | International Journal of Ophthalmology(English edition)2019，12，4： | 9 |
| 5 | 考虑全局不等约束的多代理系统分布式需求响应优化显示文摘文章深入研究了由批发商和多个需求响应聚合商(demand response aggregators,DRA)参与的分布式需求响应优化策略,其中批发商可根据用户负荷形状确定DRA的电力支付。分布式需求响应能够激励广泛分布的能源系统根据调度请求调整用能计划。然而,需求响应优化问题一般包含全局状态量的和全局不等约束,使得该问题难以通过分布式的方式求解。这限制了需求响应的可行性和盈利潜力。针对这些挑战,设计了一种适用于分布式需求响应的多代理需求响应架构。其次,提出一种基于数据驱动的需求响应弹性特征的在线提取方法。针对目标函数中的全局变量和全局不等约束,在分层优化中分别提出了离散奇异一致性算法和分布式扰动原对偶子梯度(distributed perturbation primal-dual sub-gradient,D-PPDS)算法,该算法支持多个DRA非同步并行优化。最后,利用山东某实际工业园区数据模拟并验证了所提策略的有效性。 | 郝然 艾芊 张宇帆 孙树敏 姜子卿 Mohammed Yousif | 2019 | 电网技术2019，43，9： | 7 |
| 6 | Etiological risk factors for subfertility among Palestinian women in Gaza显示文摘The inability to procreate is frequently considered a personal tragedy and a hardship for couples, impacting on the entire family and even the local community. In Gaza strip, Palestine, there has been no study on etiological risk factors for subfertility. The present study aimed to identify risk factors associated with subfertility among women in Gaza, Palestine. One hundred and sixty-nine women in the study group and 115 women in the control group were included. Cases were selected randomly from those referred to the Al Basma Fertility Center, Gaza, Palestine. Data were collected through close-ended questionnaire, sonography, hormonal analysis and thrombophilia profile that included the methylenetetrahydrofolate reductase (MTHFR 677 C > T), factor V leiden (1691 G > A) and prothrombin (20210 G > A) genes. By using univariate analyses, the effects of different patient-related variables on the presence of subfertility were evaluated. A multiple logistic regression model was constructed, crude and adjusted odds ratios (OR) and 95% confidence intervals (95% CI) were calculated. The findings showed that 73.5 % (169/230) of the women referred to the Al Basma Center sought treatment for subfertility. Different etiological risk factors were associated with subfertility, the most frequent of which in descending order were: thrombophilic disorders, fallopian tube problems, sex hormone abnormalities and polycystic ovary syndrome with an adjusted OR of 21.42, 13.63, 11.69 and 10.29, respectively. In conclusion, several etiological risk factors are responsible for subfertility among women in Gaza. Comprehensive evaluation of infertile women should be considered in the course of treatment; otherwise, the duration of sterility may be extended. | Mahmoud Mohammed Sirdah Abdelnasser Kassem Abushahla Bahaa Yousif Ghalayeni Ahmed Gamel Aburamadan | 2013 | The Journal of Biomedical Research2013，27，2： | 4 |

| 8 | An Optimal Dispatch Strategy for Distributed Microgrids Using PSO显示文摘Grid structures are rapidly evolving in view of contemporary energy policies which ensure the addition of more renewable sources to reduce the carbon footprint.Compared to a centralized approach,low voltage grids(decentralized and distributed)are promising approaches to integrating nondispatchable renewable energy sources(RESs).Installing local micro level power generation sources such as fuel cells,microturbines,and energy storage systems are a recent trend which helps in the intermittent effects of RESs and makes microgrids less dependable on the main grid.Due to the increasing variety of distributed generation sources having diverse characteristics,power dispatch scheduling of distributed microgrids is becoming challenging.A dispatch scheduling solution from an operator’s point of view is presented by the authors.The core objective of this study is to minimize the carbon emissions and the cost of each microgrid.Further,it is observed that sales and purchases from the main grid are reduced.Consequently,transmission losses are also decreased. | Muhammad Yousif Qian Ai Yang Gao Waqas Ahmad Wattoo Ziqing Jiang Ran Hao | 2020 | CSEE Journal of Power and Energy Systems2020，6，3： | 3 |

Patients with portal hypertension presenting with acute variceal haemorrhage secondary to either liver cirrhosis(group A) or schistosomal periportal fibroses(group B) presenting within 24 h of the onset of the bleeding were enrolled in the study and followed for a period of 6 wk. Analysis of data was done by Microsoft Excel and comparison between groups was done by Statistical Package of Social Sciences version 20 to calculate means and find the levels of statistical differences and define the mortality rates, the P value of < 0.05 was considered to be significant. RESULTS A total of 94 patients were enrolled in the study. Thirtytwo patients(34%) had liver cirrhosis(group A) and62(66%) patients had periportal fibrosis(group B).Mortality: The 6-wk and 5-d mortality were 53% and16% respectively in group A compared to 10% and 0%in group B(P value < 0.000 and < 0.004). In group A;a Child-Turcotte-Pugh class C and rebleeding within 5 d were significantly associated with 5-d mortality(P value< 0.029 and < 0.049 respectively) and Child- TurcottePugh class C was also a significant risk factor for 6-wk mortality(P value < 0.018). In group B; mortality was significantly associated with rebleeding within the 6-wk follow-up period and requirement for blood transfusion on admission(P value < 0.005 and < 0.049). Rebleeding:The 6-wk and 5-d rebleeding rate in group A were 56%and 25% respectively compared to 32% and 3% in group B(P value < 0.015 and < 0.002). Clinical presentation with encephalopathy was a significant risk factor for 5 d rebleeding in group A(P value < 0.005) while grade Ⅲperiportal fibrosis and requirement for blood transfusion on admission were significant risk factors for 6-wk rebleeding in group B(P value < 0.004 and < 0.02).CONCLUSION The 6-wk and 5-d mortality and rebleeding rate were significantly higher in patients with liver cirrhosis compared to patients with schistosomal periportal fibrosis. | Sara Elfadil Abbas Mohammed Abdelmunem Eltayeb Abdo Hatim Mohamed Yousif Mudawi | 2016 | World Journal of Hepatology2016，8，31： | 3 |

| 15 | Effect of vitamin E and human placenta cysteine peptidase inhibitor on expression of cathepsins B and L in implanted hepatoma Morris 5123 tumor model in Wistar rats显示文摘AIM: To examine the effectiveness of human placental inhibitors, by injecting vitamin E to rats with transplanted Norris-5123 hepatoma, on the expression of cathepsins B and L in tumor, liver, lung and blood sera after transplantation of Norris 5123 hepatoma.METHODS: Animals were divided into 10 groups receiving three different concentrations of vitamin E and inhibitors along or in combination and compared with negative control (healthy rats) and positive control (tumor rats). Effectiveness of treatment was evaluated with regard to survival time,tumor response and determination of the activities of proteolytic enzymes and their inhibitors using flurogenic substrates.RESULTS: Cathepsins B and L activities were elevated by 16-fold in comparison with negative control tissues, and their endogenous inhibitor activity decreased by 1.2-fold before treatment. In several cases, tumors completely disappeared following vitamin E plus human placental cyteine protease inhibitor (CPI) compared with controls.The number of complete tumor responses was higher when 20 m/kg vitamin E plus 400 μg of CPI was used, i.e.7/10 rats survived more than two mo. Cathepsins B and L were expressed significantly in tumor, liver, lung tissues and sera in parallel to the increasing of the endogenous inhibitor activity compared with the controls after treatment (P<0.0001).CONCLUSION: The data indicate formation of metastasis significantly reduced in treated rats, which might provide a therapeutic basis for anti-cancer therapy. | Tadeusz Sebzda Piotr Hanczyc Yousif Saleh Bernice F Akinpelumi Maciej Siewinski Jerzy Rudnicki | 2005 | World Journal of Gastroenterology2005，11，4： | 2 |
| 16 | Interval Type-2 fuzzy position control of electro-hydraulic actuated robotic excavator显示文摘This paper deals with fuzzy intelligent position control of electro-hydraulic activated robotic excavator for the control of boom, arm and bucket axes. Intelligent control systems are required to overcome undesirable stick-slip motion, limit cycles and oscillations. Models of electro-hydraulic servo controlled front end loader excavators are highly nonlinear. The nonlinear model accounts for fluid flow rate of valve, pump hydraulics, and friction forces. The friction forces are modelled by Coulomb, viscous and Stribeck function. Interval Type-2 Fuzzy Logic Controller (IT2FLC) is used to study the time-domain position responses of axes in the presence of external applied load. It has the ability to control the position of each of the three axes with minimum actuator position errors. Models presented are accurate and study the dynamics of the actuator and load. To improve the transient behaviour of the robotic excavator, we eliminated jitter of the bucket movement in the presence of nonlinearities. | Hassan Mohammed Yousif Kothapalli Ganesh | 2012 | International Journal of Mining Science and Technology2012，22，3： | 2 |

| 18 | Experimental evaluation of Candonocypris novaezelandiae(Crustacea:Ostracoda) in the biocontrol of Schistosomiasis mansoni transmission显示文摘Objective:To test Candonocypris novaezelandiae(Baird)(C.novaezelandiae),sub-class Ostracoda,obtained from the Nile,Egypt for its predatory activity on snail,Biomphalaria alexandrina(B.alexandrina),intermediate host of Schistosoma mansoni(S.mansoni)and on the free-living larval stages of this parasite(miracidia and cercariae).Methods:The predatory activity of C.novaezelandiae was determined on B.alexandrina snail(several densities of eggs,newly hatched and juveniles).This activity was also determined on S.mansoni miracidia and cercariae using different volumes of water and different numbers of larvae.C.novaezelandiae was also tested for its effect on infection of snails and on the cercarial production.Results:C.novaezelandiae was found to feed on the eggs,newly hatched and juvenile snails,but with significant reduction in the consumption in the presence of other diet like the blue green algae(Nostoc muscorum).This ostracod also showed considerable predatory activity on the free-living larval stages of S.mansoni which was affected by certain environmental factors such as volume of water,density of C.novaezelandiae and number of larvae of the parasite.Conclusions:The presence of this ostracod in the aquatic habitat led to significant reduction of snail population,infection rate of snails with schistosme miracidia as well as of cercarial production from the infected snails.This may suggest that introducing C.novaezelandiae into the habitat at schistosome riskv sites could suppress the transmission of the disease. | Fouad Yousif Sherif Hafez Samia El Bardicy Menerva Tadros Hoda Abu Taleb | 2013 | Asian Pacific Journal of Tropical Biomedicine2013，3，4： | 2 |
| 19 | Truth lies below: A case report and literature review of typical appearing polyps yet with an atypical diagnosis显示文摘BACKGROUND Enteropathy associated T-cell lymphoma(EATL) is a rare form of peripheral Tcell lymphoma and makes up less than 5% of gastrointestinal lymphomas. EATL can be divided into type 1 which is associated with celiac disease, and monomorphic epitheliotropic intestinal T-cell lymphoma(MEITL), formally type 2, which is not associated with celiac disease.CASE SUMMARY We present a 60-year-old African American female, without celiac disease, who presented with abdominal pain, diarrhea, and 30 lb. weight loss over a 3 month period. She was subsequently diagnosed with EATL throughout her entire gastrointestinal tract. She is currently undergoing chemotherapy with EOCH(Etoposide, Oncovin, Cyclophosphamide, and Hydroxydaunorubicin). EATL is most common in the Asian and Hispanic population yet the incidence in African Americans is uncertain and emphasizes the rarity of this case. A literature review was included to further emphasize similarities and differences between our case and previously reported cases of MEITL.CONCLUSION The patient was diagnosed with EATL, immunochemical testing was not conclusive for MEITL however was suggestive of the disease. | Aaron Fisher Edward Yousif Marc Piper | 2019 | World Journal of Gastrointestinal Endoscopy2019，11，1： | 2 |
