| 1 | Numerical and experimental comparison of the vaned diffuser interaction inside the impeller velocity field of a centrifugal pump显示文摘The paper refers to the analysis of interactions between the impeller and the vaned diffuser based on the air model of a radial flow pump.The study deals with a numerical simulation of the flow for a full 360°entire impeller and diffuser.The task is carried out closely under the design operating conditions and for one particular position of the impeller blade with respect to the diffuser frame.Among all the results,the focus is mainly on the flow pattern at the exit part inside the impeller facing the diffuser vanes.The results are compared to the available PIV measurements. | ATIF Abdelmadjid BENMANSOUR Saad BOIS Gerard DUPONT Patrick | 2011 | Science China(Technological Sciences)2011，54，2： | 13 |
| 2 | Terlipressin and hepatorenal syndrome: What is important for nephrologists and hepatologists显示文摘Hepatorenal syndrome (HRS) is a reversible form of functional renal failure that occurs with advanced hepatic cirrhosis and liver failure. Despite mounting research in HRS, its etiology and medical therapy has not been resolved. HRS encompasses 2 distinct types. Type 1 is characterized by the rapid development of renal failure that occurs within 2 wk and involves a doubling of initial serum creatinine. Type 2 has a more insidious onset and is often associated with ascites. Animal studies have shown that both forms, in particular type 1 HRS, are often precipitated by bacterial infections and cir-culatory changes. The prognosis for HRS remains very poor. Type 1 and 2 both have an expected survival time of 2 wk and 6 mo, respectively. Progression of liver cir-rhosis and the resultant portal hypertension leads to the pooling of blood in the splanchnic vascular bed. The ensuing hyperdynamic circulation causes an ineffective circulatory volume which subsequently activates neuro-hormonal systems. Primarily the sympathetic nervoussystem and the renin angiotensin system are activated, which, in the early stages of HRS, maintain adequate circulation. Both advanced cirrhosis and prolonged ac-tivation of neurohormonal mechanisms result in fatal complications. Locally produced nitric oxide may have the potential to induce a deleterious vasodilatory effect on the splanchnic circulation. Currently medical therapy is aimed at reducing splanchnic vasodilation to resolve the ineffective circulation and maintain good renal per-fusion pressure. Terlipressin, a vasopressin analogue, has shown potential benefit in the treatment of HRS. It prolongs both survival time and has the ability to re-verse HRS in the majority of patients. In this review we aim to focus on the pathogenesis of HRS and its treatment with terlipressin vs other drugs. | Ahmed A Magan Atif A Khalil Mohamed H Ahmed | 2010 | World Journal of Gastroenterology2010，16，41： | 11 |

| 5 | Visually constructing the chemical structure of a single molecule by scanning Raman picoscopy显示文摘The strong spatial confinement of a nanocavity plasmonic field has made it possible to visualize the inner structure of a single molecule and even to distinguish its vibrational modes in real space.W ith such ever-improved spatial resolution,it is anticipated that full vibrational imaging of a molecule could be achieved to reveal molecular structural details.Here we demonstrate full Raman images of individual vibrational modes at the angstrom level for a single Mg-porphine molecule;revealing distinct characteristics of each vibrational mode in real space.Furthermore,by exploiting the underlying interference effect and Raman fingerprint database,we propose a new methodology for structural determination,which we have called'scanning Raman picoscopy',to show how such ultrahigh-resolution spectromicroscopic vibrational images can be used to visually assemble the chemical structure of a single molecule through a simple Lego-like building process. | Yao Zhang Ben Yang Atif Ghafoor Yang Zhang Yu-Fan Zhang Rui-Pu Wang Jin-Long Yang Yi Luo Zhen-Chao Dong J.G.Hou | 2019 | National Science Review2019，6，6： | 5 |
| 6 | 7种啤酒废酵母酶解液挥发性成分对橘小实蝇的引诱作用显示文摘测试了啤酒废酵母酶解液7种挥发性成分(3-甲基-1-丁醇、苯甲醛、乙酸辛酯、乙酸苯乙酯、辛酸乙酯、苯乙腈和苯乙醇)及其混合物对不同发育期橘小实蝇的引诱效果.结果显示,乙酸辛酯、乙酸苯乙酯和辛酸乙酯对橘小实蝇雌雄成虫的引诱作用显著;利用正交试验方法得到200μL·m L-1乙酸辛酯、200μL·m L-1乙酸苯乙酯和100μL·m L-1辛酸乙酯的混合物对橘小实蝇的引诱效果最好,引诱率达到88.6%. | 杨晴阳 IDREES Atif 杜迎刚 季清娥 蔡普默 谷小红 王波 陈家骅 | 2016 | 福建农林大学学报(自然科学版)2016，45，5： | 5 |
| 7 | Screen printing of silver nanowires: balancing conductivity with transparency while maintaining flexibility and stretchability显示文摘Printing metal nanowires are particularly attractive as compared to conventional coating methods due to the ease of processing,direct patterning,and large-scale fabrication capability.However,it is still challenging to print metal nanowire patterns that simultaneously have high conductivity,high transparency,flexibility,and stretchability.Three steps have been taken in this work to balance the transparency and conductivity of the screen-printed flexible and stretchable silver nanowire films,(1)selection of the ink formulation,(2)optimization of the printing parameters,and(3)posttreatment with a laser.The as-obtained silver nanowire patterns are large-area and demonstrate an ultralow sheet resistance of 1.9 ohm/sq,high transmittance(73%)at the wavelength of 550 nm,and an ultrahigh figure of merit(~136)as compared to the printed silver nanowire electrodes in the literature.The screenprinted transparent patterns exhibit excellent electrical stability and mechanical repeatability when subjected to 1000 bending cycles with a bending radius of 28 mm and 1000 stretch-release cycles with 10%strain,which makes the transparent patterns suitable for the fabrication of flexible,transparent microwave absorbers.The absorption performance of the prepared frequency selective surface absorbers indicates no obvious degradation after various manipulating configurations and multiple bending and stretching cycles.The results are promising enough to make this ink and screen-printing process suitable for many applications of flexible,stretchable,and transparent electronics. | Weiwei Li Shuai Yang Atif Shamim | 2019 | npj Flexible Electronics2019，3，1： | 5 |
| 8 | Enhanced Reversible Zinc Ion Intercalation in Deficient Ammonium Vanadate for High-Performance Aqueous Zinc-Ion Battery显示文摘Ammonium vanadate with bronze structure(NH_(4)V_(4)O_(10))is a promising cathode material for zinc-ion batteries due to its high specific capacity and low cost.However,the extraction of NH^(+)_(4) at a high voltage during charge/discharge processes leads to irreversible reaction and structure degradation.In this work,partial NH^(+)_(4) ions were pre-removed from NH_(4)V_(4)O_(10) through heat treatment;NH_(4)V_(4)O_(10) nanosheets were directly grown on carbon cloth through hydrothermal method.Defi-cient NH_(4)V_(4)O_(10)(denoted as NVO),with enlarged interlayer spacing,facilitated fast zinc ions transport and high storage capacity and ensured the highly reversible electrochemical reaction and the good stability of layered structure.The NVO nanosheets delivered a high specific capac-ity of 457 mAh g^(−1) at a current density of 100 mA g^(−1) and a capacity retention of 81%over 1000 cycles at 2 A g^(−1).The initial Coulombic efficiency of NVO could reach up to 97%compared to 85%of NH_(4)V_(4)O_(10) and maintain almost 100%during cycling,indicating the high reaction reversibility in NVO electrode. | Quan Zong Wei Du Chaofeng Liu Hui Yang Qilong Zhang Zheng Zhou Muhammad Atif Mohamad Alsalhi Guozhong Cao | 2021 | Nano-Micro Letters2021，13，8： | 4 |

| 10 | Prevalence of unsuspected thyroid nodules in adults on contrast enhanced 16-and 64-MDCT of the chest显示文摘AIM: To determine the prevalence of unsuspected thyroid nodules on contrast enhanced 16and 64-modified discrete cosine transform (MDCT) of the chest, in a population of adult outpatients imaged for indications other than thyroid disease. METHODS: This retrospective study involved review of intravascular contrast-enhanced MDCT scans of the chest from 3077 consecutive adult outpatients, to identify unsuspected thyroid nodules. Exclusion criteria included history of thyroid cancer, known thyroid nodules or thyroid disease and risk factors for thyroid cancer, as evidenced by their medical records. One of 9 radiologists recorded number of nodules, location and bidirectional measurement of largest nodule, as well as amount of thyroid visualized on the chest computed tomography (CT). Presence of nodule was correlated with age, gender, race and percentage of thyroid imaged. RESULTS: A total of 2510 (2510/3077 or 81.6%) study subjects were included in the data analysis; among them,one or more nodules were identified in 629 subjects (629/2510 or 25.1%), with 242 (242/629 or 38.5%) having multiple nodules. Patients with nodule(s) were significantly older than those without (64 ± 13 years vs 58 ± 14 years, P < 0.0001), and female gender was associated with presence of nodule(s) (373/1222 or 30.5% vs 256/1288 or 19.9%, P < 0.0001). Women were also more likely having multiple nodules (167/373 or 44.8%) compared to men (75/256 or 29.3%, P < 0.0001). The majority of nodules (427/629 or 67.9%) were less than 1 cm. CONCLUSION: This retrospective review revealed a prevalence of 25.1% for unsuspected thyroid nodules on contrast-enhanced chest CT. | Sameer Ahmed Pamela T Johnson Karen M Horton Atif Zaheer Saline Tsai Elliot K Fishman | 2012 | World Journal of Radiology2012，4，7： | 4 |

| 12 | Viral respiratory infections among Hajj pilgrims in 2013显示文摘Middle East respiratory syndrome coronavirus(MERS-Co V) has emerged in the Arabian Gulf region, with its epicentre in Saudi Arabia, the host of the ‘Hajj' which is the world's the largest mass gathering. Transmission of MERS-Co V at such an event could lead to its rapid worldwide dissemination. Therefore, we studied the frequency of viruses causing influenza-like illnesses(ILI) among participants in a randomised controlled trial at the Hajj 2013. We recruited 1038 pilgrims from Saudi Arabia, Australia and Qatar during the first day of Hajj and followed them closely for four days. A nasal swab was collected from each pilgrim who developed ILI. Respiratory viruses were detected using multiplex RT-PCR. ILI occurred in 112/1038(11%) pilgrims. Their mean age was 35 years, 49(44%) were male and 35(31%) had received the influenza vaccine pre-Hajj. Forty two(38%) pilgrims had laboratory-confirmed viral infections; 28(25%) rhinovirus, 5(4%) influenza A, 2(2%) adenovirus, 2(2%) human coronavirus OC43/229 E, 2(2%) parainfluenza virus 3, 1(1%) parainfluenza virus 1, and 2(2%) dual infections. No MERS-Co V was detected in any sample. Rhinovirus was the commonest cause of ILI among Hajj pilgrims in 2013. Infection control and appropriate vaccination are necessary to prevent transmission of respiratory viruses at Hajj and other mass gatherings. | Osamah Barasheed Harunor Rashid Mohammad Alfelali Mohamed Tashani Mohammad Azeem Hamid Bokhary Nadeen Kalantan Jamil Samkari Leon Heron Jen Kok Janette Taylor Haitham El Bashir Ziad A.Memish Elizabeth Haworth Edward C.Holmes Dominic E Dwyer Atif Asghar Robert Booy | 2014 | Virologica Sinica2014，29，6： | 3 |
| 13 | Surface plasmon polariton at the interface of dielectric and graphene medium using Kerr effect显示文摘We theoretically investigate the control of surface plasmon polariton(SPP) generated at the interface of dielectric and graphene medium under Kerr nonlinearity. The controlled Kerr nonlinear signal of probe light beam in a dielectric medium is used to generate SPPs at the interface of dielectric and graphene medium. The positive, negative absorption, and dispersion properties of SPPs are modified and controlled by the control and Kerr fields. A large amplification(negative absorption) is noted for SPPs under the Kerr nonlinearity. The normal/anomalous slope of dispersion and propagation length of SPPs is modified and controlled with Kerr nonlinearity. This leads to significant variation in slow and fast SPP propagation. The controlled slow and fast SPP propagation may predict significant applications in nano-photonics, optical tweezers, photovoltaic devices, plasmonster, and sensing technology. | Bakhtawar Muhammad Haneef B A Bacha H Khan M Atif | 2018 | Chinese Physics B2018，27，11： | 3 |
| 14 | Enhanced adsorptive removal of Cr(VI)in aqueous solution by polyethyleneimine modified palygorskite显示文摘Polyethyleneimine(PEI)modified palygorskite(Pal)was used for the adsorption of Cr(VI)in aqueous solution.The absorbent was characterized by Fourier transform infrared spectroscopy(FT-IR)and thermogravimetric analysis(TGA).Characterized results confirmed that the Pal has been successfully modified by PEI.The modification of PEI increased the Cr(VI)adsorption performance of the Pal by the adsorption combined reduction mechanism,and amino groups of the adsorbent play the main role in the enhanced Cr(VI)adsorption.The maximum adsorption capacity was 51.10 mg·g^-1 at pH4.0 and 25°C.The adsorption kinetics of Cr(VI)on the adsorbent conforms to the Langmuir isotherm model.The maximum adsorption occurs at pH3,and then the adsorption capacity of PEI-Pal was decreased with the increase of p H values.The adsorption kinetics of Cr(VI)on PEI-Pal was modeled with pseudo-second-order model.The addition of Cl^-,SO4^2-and PO4^3-reduced the Cr(VI)adsorption by competition with Cr(VI)for the active sites of PEI-Pal.The Cr(VI)saturated PEI-Pal can be regenerated in alkaline solution,and the adsorption capacity can still be maintained at 30.44 mg·g^-1 after 4 cycles.The results demonstrate that PEI-Pal can be used as a potential adsorbent of Cr(VI)in aqueous solutions. | Jiahong Wang Tongtong Sun Atif Saleem Yao Chen | 2020 | Chinese Journal of Chemical Engineering2020，28，10： | 3 |
| 15 | Coat-and-print patterning of silver nanowires for flexible and transparent electronics显示文摘Silver nanowires(Ag NWs)possess excellent optoelectronic properties,which have led to many technology-focused applications of transparent and flexible electronics.Many of these applications require patterning of Ag NWs into desired shapes,for which maskbased and printing-based techniques have been developed and widely used.However,there are still several limitations associated to these techniques.These limitations,such as complicated patterning procedures,limited patterning area,and compromised optical transparency,hamper the efficient fabrication of high-performance Ag NW patterns.Here,we propose a coat-and-print approach for effectively patterning Ag NWs.We printed a polymer-based ink on the spin-coated Ag NW films.The ink acts as a protective layer to help remove excess Ag NWs from the substrate and then dissolves itself into an organic solvent.In this way,we can take advantage of both coating-based techniques(lead to Ag NWs with high transparency)and printing-based techniques(efficiently pattern diverse shapes).The resultant Ag NW patterns exhibit comparable conductivity(sheet resistance:7.1 to 30 Ohm/sq)and transparency(transmittance:84 to 95%atλ=550 nm)to those made by conventional coating methods.In addition,the patterned Ag NWs exhibit robust mechanical stability and reliability,surviving extensive bending and peeling tests.Due to higher conductivity,efficient patterning ability and inherent transparency,this material system and application method is highly suitable for transparent and flexible electronics.As a proof of concept,this research demonstrates a wide-band antenna,operating in the mm-wave range that includes the 5G communication band.The proposed antenna exhibits a wide bandwidth of 26 GHz(from 17.9 GHz to 44 GHz),robust return loss under 1000 cyclic bending(bending radius of 3.5 mm),and decent transparency over the entire visible wavelength(86.8%transmittance atλ=550 nm).This work’s promising results indicate that this method can be adapted for roll-to-roll manufacturing to efficiently produce patterned and optically transparent devices. | Weiwei Li Azat Meredov Atif Shamim | 2019 | npj Flexible Electronics2019，3，1： | 3 |

| 17 | Multiple Deep-Belief-Network-Based Spectral-Spatial Classification of Hyperspectral Images显示文摘A deep-learning-based feature extraction has recently been proposed for HyperSpectral Images(HSI)classification. A Deep Belief Network(DBN), as part of deep learning, has been used in HSI classification for deep and abstract feature extraction. However, DBN has to simultaneously deal with hundreds of features from the HSI hyper-cube, which results into complexity and leads to limited feature abstraction and performance in the presence of limited training data. Moreover, a dimensional-reduction-based solution to this issue results in the loss of valuable spectral information, thereby affecting classification performance. To address the issue, this paper presents a Spectral-Adaptive Segmented DBN(SAS-DBN) for spectral-spatial HSI classification that exploits the deep abstract features by segmenting the original spectral bands into small sets/groups of related spectral bands and processing each group separately by using local DBNs. Furthermore, spatial features are also incorporated by first applying hyper-segmentation on the HSI. These results improved data abstraction with reduced complexity and enhanced the performance of HSI classification. Local application of DBN-based feature extraction to each group of bands reduces the computational complexity and results in better feature extraction improving classification accuracy. In general, exploiting spectral features effectively through a segmented-DBN process and spatial features through hyper-segmentation and integration of spectral and spatial features for HSI classification has a major effect on the performance of HSI classification. Experimental evaluation of the proposed technique on well-known HSI standard data sets with different contexts and resolutions establishes the efficacy of the proposed techniques,wherein the results are comparable to several recently proposed HSI classification techniques. | Atif Mughees Linmi Tao | 2019 | Tsinghua Science and Technology2019，24，2： | 3 |
| 18 | 磷肥对甜玉米籽粒植酸和锌有效性的影响显示文摘为明确磷肥对甜玉米籽粒营养特性的影响,利用不同品种的磷肥定位试验以及磷肥梯度水平试验,探讨甜玉米籽粒植酸、磷(P)、锌(Zn)含量及Zn有效性的时间(不同灌浆期)和空间(果穗上、中、下部;籽粒果皮、胚乳和胚)变化及其对外源磷肥的响应特性。试验结果表明,甜玉米籽粒的P和植酸含量随磷肥用量的增加而增加,Zn含量及其有效性则呈现下降趋势。磷肥投入对吐丝后16~24 d籽粒的植酸、P和Zn的积累(mg plant(^-1))的影响最为显著,而对不同灌浆时期Zn有效性均表现出抑制效应。在中磷水平下,果穗不同穗位籽粒植酸(g kg^(-1))和Zn有效性的差异并不显著。高磷水平显著提高了中、下部果穗植酸的含量,但对不同穗位籽粒Zn含量和Zn有效性均存在抑制效应。对籽粒内不同部位(果皮、胚乳和胚)进行比较,植酸、P以及Zn含量均以胚中含量最高,积累量占比则以胚乳中最高;而Zn有效性以胚中最高。高磷处理可显著提高籽粒内不同部位植酸和磷含量,降低Zn含量及其有效性。综上,合理磷肥施用可促进籽粒Zn积累,而过量磷肥投入会显著增加不同灌浆时期,以及胚乳和胚中的植酸含量和积累量,并最终对甜玉米不同穗位籽粒和籽粒内不同部位Zn有效性都产生一定程度的抑制效应,相关研究或为甜玉米籽粒Zn有效性的提高提供理论参考。 | 苏达 颜晓军 蔡远扬 梁恬 吴良泉 MUHAMMAD Atif Muneer 叶德练 | 2022 | 作物学报2022，48，1： | 3 |

| 20 | Bed planting of wheat(Triticum aestivum L.)improves nitrogen use efficiency and grain yield compared to flat planting显示文摘Conventional flat planting is commonly used for growing wheat in Pakistan and the crop is irrigated by flood irrigation, but it leads to ineffective use of applied nitrogen owing to poor aeration and leaching and volatilization losses. The practice also results in greater crop lodging, lower water use efficiency, and crusting of the soil surface. In contrast, bed planting of wheat not only saves water but improves fertilizer use efficiency and grain yield. Three years of pooled data from the present study showed that wheat planting on beds and nitrogen application at 120 kg ha-1produced 15.06% higher grain yield than flat planting at the same nitrogen rate. Similarly, 25.04%, 15.02%, 14.59%, and 29.83% higher nitrogen uptake, nitrogen use, and agronomic and recovery efficiencies, respectively, were recorded for bed compared to flat planting. Wheat planting on beds with a nitrogen application of80 kg ha-1gave a yield similar to that of flat planting with 120 kg ha-1nitrogen. However,the economic return was 29% higher in bed planting as compared to flat planting, when nitrogen was applied at 120 kg ha-1. | Abdul Majeed Atif Muhmood Abid Niaz Shahid Javid Zahid Ashfaq Ahmad Syed Shahid Hussain Shah Asrar Hussain Shah | 2015 | The Crop Journal2015，3，2： | 3 |
