| 6 | 2015年4月25日尼泊尔地震波场传播及烈度初步模拟分析显示文摘2015年4月25日尼泊尔发生Mw7.9地震.本文采用三维曲线坐标网格有限差分方法,依据USGS给出的震源运动学反演结果和震源区域地形数据,模拟了尼泊尔地震波场传播过程,得到震源区域烈度分布模拟结果,与实际观测的地表峰值速度(PGV)大体吻合.结果表明:地震烈度的空间分布整体上受控于震源的单边破裂特征,高烈度区域主要分布在破裂传播方向上,即震源东半部.震源南侧到东南侧近场,由于受到震源和地形的双重影响,形成最大烈度分布区域,最大烈度约为IX.南侧平原受低速沉积层影响形成高烈度区域.震源西侧及盆地内烈度相对较低. | 徐剑侠 张振国 戴文杰 张伟 Naveed Akram 文健 陈晓非 | 2015 | 地球物理学报2015,58,5: | 6 |
| 7 | 不同结构SAPO-34催化剂上1-己烯催化裂解制丙烯(英文)显示文摘制备了100%SAPO-34,30%SAPO-34和介孔-SAPO-34三种不同类型的SAPO-34分子筛催化剂,并采用氮吸附、扫描电镜、X射线衍射和红外光谱等方法对催化剂进行了表征.三种催化剂的微孔结构、比表面积和总酸量近似,但具有不同的催化剂组成和次级结构.以1-己烯裂解为模型反应考察了三种催化剂的催化活性.对于30%SAPO-34催化剂,由于添加了粘结剂,其外表面酸性和扩散性能下降,导致催化活性降低;100% SAPO-34催化剂则具有较好的催化性能;介孔SAPO-34催化剂次级结构的存在使其失活较慢,从而提高了原料的转化率.详细讨论了1-己烯催化裂解制丙烯的活性和选择性曲线,以进一步说明催化剂组成和结构的影响. | Zeeshan NAWAZ 汤效平 朱杰 魏飞 Shahid NAVEED | 2009 | 催化学报2009,30,10: | 5 |
| 8 | Estimating the basic reproductive ratio for the Ebola outbreak in Liberia and Sierra Leone显示文摘Background:Ebola virus disease has reemerged as a major public health crisis in Africa,with isolated cases also observed globally,during the current outbreak.Methods:To estimate the basic reproductive ratio R0,which is a measure of the severity of the outbreak,we developed a SEIR(susceptible-exposed-infected-recovered)type deterministic model,and used data from the Centers for Disease Control and Prevention(CDC),for the Ebola outbreak in Liberia and Sierra Leone.Two different data sets are available:one with raw reported data and one with corrected data(as the CDC suspects under-reporting).Results:Using a deterministic ordinary differential equation transmission model for Ebola epidemic,the basic reproductive ratio R0 for Liberia resulted to be 1.757 and 1.9 for corrected and uncorrected case data,respectively.For Sierra Leone,R0 resulted to be 1.492 and 1.362 for corrected and uncorrected case data,respectively.In each of the two cases we considered,the estimate for the basic reproductive ratio was initially greater than unity leading to an epidemic outbreak.Conclusion:We obtained robust estimates for the value of R0 associated with the 2014 Ebola outbreak,and showed that there is close agreement between our estimates of R0.Analysis of our model also showed that effective isolation is required,with the contact rate in isolation less than one quarter of that for the infected non-isolated population,and that the fraction of high-risk individuals must be brought to less than 10%of the overall susceptible population,in order to bring the value of R0 to less than 1,and hence control the outbreak. | Adnan Khan Mahim Naveed Muhammad Dur-e-Ahmad Mudassar Imran | 2015 | Infectious Diseases of Poverty2015,4,1: | 5 |

| 11 | 在稍尖的巨大的肺的栓塞的机械故障和 thrombolysis : 未来的试用显示文摘 AIM: To assess role of combined modality of mechanical fragmentation and intralesional thrombolysis in patients with massive pulmonary embolism presenting subacutely. METHODS: Eight of 70 patients presenting in tertiary care centre of North India with massive pulmonary embolism within 4 years had subacute presentation (symptom onset more than 2 wk). These patients were subjected to pulmonary angiography with intention to treat basis via mechanical breakdown and intra lesional thrombolysis. Mechanical breakdown of embolus was accomplished with 5-F multipurpose catheter to reestablish flow, followed by intralesional infusion of urokinase (4400 IU/kg over 10 min followed by 4400 IU/kg per hour over 24 h). RESULTS: Eight patients, mean age 47.77±12.20 years presented with subacute pulmonary embolism (mean duration of symptoms 2.4 wk). At presentation, mean heart rate, shock index, miller score and mean pulmonary pressures were 101.5±15.2/min, 0.995±0.156, 23.87±3.76 and 37.62±6.67 mmHg which reduced to 91.5±12.2/min (P=0.0325), 0.789±0.139 (P=0.0019), 5.87±1.73 (P=0.0000004) and 27.75±8.66 mmHg (P=0.0003) post procedurally. Mean BP improved from 80.00±3.09 mmHg to 90.58±9.13 mmHg (P=0.0100) post procedurally. Minor complications in the form of local hematoma-minor hematoma in 1 (12.5%), and pseudoaneurysm (due to femoral artery puncture) in 1 (12.5 %) patient were seen. At 30 d and 6 mo follow up survival rate was 100% and all the patients were asymptomatic and in New York Heart Association class 1. CONCLUSION: Combined modality of mechanical fragmentation and intralesional thrombolysis appears to be a promising alternative to high risk surgical procedures in patients with subacute massive pulmonary embolism. | Bishav Mohan Shibba Takkar Chhabra Naved Aslam Gurpreet Singh Wander Naresh Kumar Sood Sumati Verma Anil Kumar Mehra Sarit Sharma | 2013 | World Journal of Cardiology2013,5,5: | 5 |
| 12 | Clinical course of suspected small gastrointestinal stromal tumors in the stomach显示文摘BACKGROUND Gastric subepithelial lesions are frequently encountered during endoscopic examinations,and the majority of them are small and asymptomatic.Among these lesions,gastrointestinal stromal tumors(GISTs)are the major concern for patients and clinicians owing to their malignant potentials.Although previous guidelines suggested periodic surveillance for such small(≤20 mm)lesions,several patients and clinicians have still requested or prescribed repeated examinations or radical resection,posing extra medical burdens and risks.AIM To describe the clinical course of suspected small gastric GISTs and provide further evidence for surveillance strategy for tumor therapy.METHODS This single-center,retrospective study was conducted at West China Hospital,Sichuan University.Consecutive patients with suspected small gastric GISTs were reviewed from November 2004 to November 2018.GIST was suspected according to endoscopic ultrasonography features:hypoechoic lesions from muscularis propria or muscularis mucosa.Eligible patients with suspected small(≤20 mm)GISTs were included for analysis.Patients’demographic data,lesions’characteristics,and follow-up medical records were collected.RESULTS A total of 383 patients(male/female,121/262;mean age,54 years)with 410 suspected small gastric GISTs(1 lesion in 362 patients,2 lesions in 16,3 lesions in4,and 4 lesions in 1)were included for analysis.The most common location was gastric fundus(56.6%),followed by body(29.0%),cardia(12.2%),and antrum(2.2%).After a median follow-up of 28 mo(interquartile range,16-48;range,3-156),402 lesions(98.0%)showed no changes in size,and size of 8 lesions(2.0%)was increased(mean increment,10 mm).Of the 8 lesions with size increment,endoscopic or surgical resection was performed in 6 patients(5 GISTs and 1 leiomyoma).For other 2 remaining patients,unroofing biopsy or endoscopic ultrasound-guided fine-needle aspiration was carried out(2 GISTs),while no further change in size was noted over a period of 62-64 mo.CONCLUSION The majority of suspected small(≤20 mm)gastric GISTs had no size increment during follow-up.Regular endoscopic follow-up without pathological diagnosis may be highly helpful for such small gastric subepithelial lesions. | Lian-Song Ye Yan Li Wei Liu Ming-Hong Yao Naveed Khan Bing Hu | 2020 | World Journal of Gastrointestinal Surgery2020,12,4: | 4 |

| 15 | Effect of seedling age and water depth on morphological and physiological aspects of transplanted rice under high temperature显示文摘To study the effect of high temperature, rice seedlings 20, 30, 40 and 50 d were kept at 5, 10, 15 and 20 cm water depth in a water pool. Meteorological findings indicated that water temperature varied up to 10 cm but became stable below this depth. Deep water inflicted higher tiller mortality, minimal increase in dry weight of aerial parts and leaf area, decrease in root length, and decrease in root dry weight especially at 20 cm water depth and produced an unbalanced T/R ratio (top versus root dry weight). However, deep water tended to increase plant length. These parameters, however, excel in shallow water. Older seedlings, with the exception of root dry weight, could not perform well compared to young seedlings in all physiological and morphological aspects. The study revealed that seedlings, particularly young ones, stand well in shallow water and can cope with high temperature. | KHAKWANI Abdul Aziz SHIRAISHI Masaaki ZUBAIR Muhammad BALOCH Mohammad Safdar NAVEED Khalid AWAN Inayatullah | 2005 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2005,6,5: | 4 |
| 16 | Effects of viscous dissipation and slip velocity on two-dimensional and axisymmetric squeezing flow of Cu-water and Cu-kerosene nanofluids显示文摘Squeezing flow of nanofluids has been taken into account under the effects of viscous dissipation and velocity slip.Two types of base fluids are used to study the behavior of Copper nanoparticles between parallel plates.Nonlinear ordinary differential equations governing the flow are obtained by imposing similarity transformations on conservation laws.Resulting equations are solved by using an efficient analytical technique the variation of parameters method(VPM).Influences of nanoparticle concentration and different emerging parameters on flow profiles are presented graphically coupled with comprehensive discussions.A numerical solution is also sought for the sake of comparison.Effect of different parameters on skin friction coefficient and Nusselt number is also discussed. | Umar Khan Naveed Ahmed Mir Asadullah Syed Tauseef Mohyud-din | 2015 | Propulsion and Power Research2015,4,1: | 4 |
| 17 | 乳酸菌发酵制备大豆奶酪豆坯的工艺研究(英文)显示文摘采用3种乳酸菌干酪乳杆菌(LC)、瑞士乳杆菌(LH)和干酪乳杆菌鼠李糖亚种6013(LR)和葡萄糖酸内酯(GDL)凝固豆乳制备豆坯,并对其质构和风味进一步改善。在6 h的凝乳发酵中可以发现LC+LH样品中发酵剂生长良好,豆乳pH下降比LC+LH+LR样品要多。GDL的添加可以促进发酵剂生长,降低豆乳pH,但是它对豆坯的质构的改善并不明显。在GDL+LH+LC+LR制备的豆坯样品中,检测到7种提供风味的和另外11种不同种类不同含量的游离氨基酸(FAA),同时,该样品的脂肪酸(FA)情况也发生显著变化(C18∶3.C20∶0,C20∶1和C22∶0除外)。除了10种常规大豆脂肪酸外,C22∶1和C24∶0也被检测到。后熟过程中这些游离氨基酸和脂肪酸的变化将会导致大豆奶酪质构和风味的改善和提高。从质构和风味上讲,LC+LH制备的豆坯是最好的,其次是LC+LH+GDL制备的豆坯。 | Naveed Ahmad 陈则华 李理 宁正祥 王永华 杨晓泉 | 2008 | 食品与机械2008,24,6: | 4 |
| 18 | Gene-gene,gene-environment,gene-nutrient interactions and single nucleotide polymorphisms of inflammatory cytokines显示文摘Inflammation plays a significant role in the etiology of type 2 diabetes mellitus(T2DM).The rise in the pro-inflammatory cytokines is the essential step in glucotoxicity and lipotoxicity induced mitochondrial injury,oxidative stress and beta cell apoptosis in T2 DM.Among the recognized markers are interleukin(IL)-6,IL-1,IL-10,IL-18,tissue necrosis factor-alpha(TNF-α),C-reactive protein,resistin,adiponectin,tissue plasminogen activator,fibrinogen and heptoglobins.Diabetes mellitus has firm genetic and very strong environmental influence; exhibiting a polygenic mode of inheritance.Many single nucleotide polymorphisms(SNPs) in various genes including those of pro and antiinflammatory cytokines have been reported as a risk for T2 DM.Not all the SNPs have been confirmed by unifying results in different studies and wide variations have been reported in various ethnic groups.The inter-ethnic variations can be explained by the fact that gene expression may be regulated by gene-gene,gene-environment and gene-nutrient interactions.This review highlights the impact of these interactions on determining the role of single nucleotide polymorphism of IL-6,TNF-α,resistin and adiponectin in pathogenesis of T2 DM. | Amina Nadeem Sadaf Mumtaz Abdul Khaliq Naveed Muhammad Aslam Arif Siddiqui Ghulam Mustafa Lodhi Tausif Ahmad | 2015 | World Journal of Diabetes2015,6,4: | 4 |

| 20 | Location-allocation modeling for emergency evacuation planning with GIS and remote sensing:A case study of Northeast Bangladesh显示文摘This work developed models to identify optimal spatial distribution of emergency evacuation centers(EECs)such as schools,colleges,hospitals,and fire stations to improve flood emergency planning in the Sylhet region of northeastern Bangladesh.The use of location-allocation models(LAMs)for evacuation in regard to flood victims is essential to minimize disaster risk.In the first step,flood susceptibility maps were developed using machine learning models(MLMs),including:Levenberg-Marquardt back propagation(LM-BP)neural network and decision trees(DT)and multi-criteria decision making(MCDM)method.Performance of the MLMs and MCDM techniques were assessed considering the area under the receiver operating characteristic(AUROC)curve.Mathematical approaches in a geographic information system(GIS)for four well-known LAM problems affecting emergency rescue time are proposed:maximal covering location problem(MCLP),the maximize attendance(MA),p-median problem(PMP),and the location set covering problem(LSCP).The results showed that existing EECs were not optimally distributed,and that some areas were not adequately served by EECs(i.e.,not all demand points could be reached within a 60-min travel time).We concluded that the proposed models can be used to improve planning of the distribution of EECs,and that application of the models could contribute to reducing human casualties,property losses,and improve emergency operation. | Mahfuzur Rahman Ningsheng Chen MdMonirul Islam Ashraf Dewan Hamid Reza Pourghasemi Rana Muhammad AliWashakh Nirdesh Nepal Shufeng Tian Hamid Faiz Mehtab Alam Naveed Ahmed | 2021 | Geoscience Frontiers2021,12,3: | 3 |
