The structure was confirmed by X-ray diffraction(XRD)while morphology was investigated by scanning electron microscopy(SEM). The electrical resistivity was observed to increase from 2.14 * 10~7 to 8.77 * 10~9 Ω-cm and activation energy was found to increase from 0.64 to 0.75 e V, while the drift mobility decreased from 4.75 * 10^(-13) to 1.27 * 10^(-15)cm^2V^(-1)S^(-1) by the substitution of Mn and Nd contents. The dielectric constant, dielectric loss and dielectric loss factor decrease with frequency and Mn-Nd contents. The saturation magnetization was increased from 34 to 70 emu g^(-1) while the coercivity decreased from 705 to 262 Oe with the increase of substituents.The increase in electrical resistivity and saturation magnetization while decrease in dielectric parameters and coercivity make these nanomaterials suitable for applications in microwave devices and longitudinal magnetic recording media. | Abdul Aziz E.Ahmed Muhammad Naeem Ashiq Muhammad Azhar Khan Nazia Karamat Irshad Ali | 2016 | Progress in Natural Science:Materials International2016，26，4： | 1 |

| 4 | Vibration analysis of damaged and undamaged steel structure systems: cantilever column and frame显示文摘This paper presents the experimental and numerical studies conducted on a steel column and a steel frame structure using free vibration analysis.The effects of damages on structures were investigated,which were simulated by introducing multiple cracks at different locations in the experimental and numerical models.The acceleration responses of the test models,were recorded through an accelerometer,and were used to calibrate the numerical models developed in finite element based software.Modal frequencies of damaged and undamaged structures were compared and analyzed,to derive relationships for damaged and undamaged structures’frequencies in terms of crack depth.It was found that,due to the presence of cracks,the mechanical properties of a structure changes,whereby,the modal frequencies decrease.An approximately linear trend was observed for the frequency decrease with the increase in crack depth,which was also confirmed by the numerical models.The derived relationships were extended to further develop a mechanics-based damage scale for steel structures,to help facilitate structural health monitoring and screening of vulnerable structures. | Muhammad Abuzar Khan Kareem Akhtar Naveed Ahmad Feroz Shah Naeem Khattak | 2020 | Earthquake Engineering and Engineering Vibration2020，19，3： | 1 |
| 5 | Weak stem under shade reveals the lignin reduction behavior显示文摘Shades caused by neighboring tall plants in intercropping systems and weak sunlight are constraints in yield optimization. Shade influences many aspects of plant growth and development, leading to weak stems and susceptibility to lodging. The plant cell wall is composed of certain proteins that allow the walls to stretch out, a process called cell wall loosening. Shade affects anatomical, morphological, and physiological traits of plants, thus reducing the physical strength of the stem in crops by changing the loosening of cell walls. Flexibility of cells facilitates further modifications such as wall loosening. In addition, shade stress causes increased internode length, and reduced xylem synthesis and photosynthesis. In shaded plants, lignin deposition in vascular bundles and sclerenchyma cells of stems is decreased. Lignin is a light sensitive phenolic compound and shading decreases the transcript abundance of several phenolic compound(flavone and lignin) related genes. Shading significantly influences the metabolic activities of phenylalanine ammonia-lyase(PAL), peroxidase(POD), 4-coumarate: CoA ligase(4 CL), and cinnamyl alcohol dehydrogenase(CAD) involved in lignin biosynthesis. Furthermore, suppression of lignin biosynthesis activities by abiotic stresses causes abnormal phenotypes such as collapsed xylem, bent stems, and growth retardation. In this review, the underlying mechanisms illustrate that under shading conditions reduced lignin content results in slender, weak, and unstable stems. The objective of this review is to elaborate lignin biosynthesis and its variability under stressful environmental conditions, especially in shade stress environments. The effects of shade on stem lignin metabolism are discussed on the morphogenetic, physiological, and proteomic levels. | Sajad Hussain Nasir Iqbal PANG Ting Muhammad Naeem Khan LIU Wei-guo YANG Wen-yu | 2019 | Journal of Integrative Agriculture2019，18，3： | 1 |

| 8 | Numerical Simulation and Experimental Verification of CMOD in SENT Specimen: Application on FCGR of Welded Tool Steel显示文摘Single-edged notched tension (SENT) specimen is used to study the fatigue crack growth rate (FCGR) behavior of AISI 50100 steel using MTS 810. Calibration tests are run to get plots of crack mouth opening displacement (CMOD) vs. load and CMOD vs. crack length-to-width ratio with the known crack lengths. Numerical simulation is also done to try to establish a relation between crack length and CMOD. FCGR of welded and un-welded specimens are plotted against stress intensity factor range to show the effect of welding on fatigue crack growth rate of AISI 50100 steel. The experimentally obtained CMOD values are compared with values obtained by numerical simulation using ABAQUS/StandardTM software package. Results show that numerical values are in good agreement with experimental data for small crack lengths and lower values of applied load. | Amir SULTAN Riffat Asim PASHA Mifrah ALI Muhammad Zubair KHAN Muhammad Afzal KHAN Naeem Ullah DAR Masood SHAH | 2013 | Acta Metallurgica Sinica(English Letters)2013，26，1： | 1 |
| 9 | Countrywide Survey for MERS-Coronavirus Antibodies in Dromedaries and Humans in Pakistan显示文摘Middle East Respiratory Syndrome Coronavirus (MERS-CoV) is a zoonotic pathogen capable of causing severe respiratory disease in humans. Although dromedary camels are considered as a major reservoir host, the MERS-CoV infection dynamics in camels are not fully understood. Through surveillance in Pakistan, nasal (n = 776) and serum (n = 1050)samples were collected from camels between November 2015 and February 2018. Samples were collected from animal markets, free-roaming herds and abattoirs. An in-house ELISA was developed to detect IgG against MERS-CoV. A total of 794 camels were found seropositive for MERS-CoV. Prevalence increased with the age and the highest seroprevalence was recorded in camels aged [ 10 years (81.37%) followed by those aged 3.1–10 years (78.65%) and B 3 years (58.19%).Higher prevalence was observed in female (78.13%) as compared to male (70.70%). Of the camel nasal swabs, 22 were found to be positive by RT-qPCR though with high Ct values. Moreover, 2,409 human serum samples were also collected from four provinces of Pakistan during 2016–2017. Among the sampled population, 840 humans were camel herders.Although we found a high rate of MERS-CoV antibody positive dromedaries (75.62%) in Pakistan, no neutralizing antibodies were detected in humans with and without contact to camels. | Ali Zohaib Muhammad Saqib Muhammad Ammar Athar Jing Chen Awais-ur-Rahman Sial Saeed Khan Zeeshan Taj Halima Sadia Usman Tahir Muhammad Haleem Tayyab Muhammad Asif Qureshi Muhammad Khalid Mansoor Muhammad Ahsan Naeem Bing-Jie Hu Bilal Ahmed Khan Ikram Din Ujjan Bei Li Wei Zhang Yun Luo Yan Zhu Cecilia Waruhiu Iahtasham Khan Xing-Lou Yang Muhammad Sohail Sajid Victor Max Corman Bing Yan Zheng-Li Shi | 2018 | Virologica Sinica2018，33，5： | 1 |
| 10 | Influence of Y^(3+),Yb^(3+),Gd^(3+) cations on structural and electromagnetic properties of CuFe_(2)O_(4) nanoferrites prepared via one step sol-gel method显示文摘Rare earths(REs) play a key role in distorting spinel structure by creating some defects at the lattice sites and make them suitable for magnetodielectric applications.In the present study,the nanoferrites of CuRE0.02Fe1.98O4,where REs=Y^(3+),Yb^(3+),Gd^(3+),were prepared using one step sol-gel method.The prepared samples are copper ferrite(CFO),yttrium doped copper ferrite(Y-CFO),ytterbium doped copper ferrite(Yb-CFO) and gadolinium doped copper ferrite(Gd-CFO),respectively.The single-phase structure of all the REs doped nanoferrites was determined by X-ray diffraction(XRD) analysis.The porosity,agglomerations and grain size of the REs doped copper ferrite were examined using field emission scanning electron microscopy(FESEM) analysis.Fourier transform infrared spectroscopy(FTIR)elaborates the phase formation and environmental effects on the REs doped nanoparticles(NPs).The recorded room temperature M-H loops from a vibrating sample magnetometer(VSM) elucidate the magnetic properties of the REs doped spinel nanoferrites.The magnetic saturation(Ms) was calculated in the range of 23.08 to 51.78 emu/g.The calculated coercivity values(272.6 to 705.60 Oe) confirm the soft magnetic behavior of REs doped copper ferrites.Furthermore,the electromagnetic and dielectric properties were assessed using a Vector network analyzer(VNA) from 1 to 6 GHz.The permeability,permittivity,dielectric tangent loss and electric modulus of the REs doped spinel ferrites illustrate that the prepared NPs may be suitable for microwave and high frequency applications. | Aleena Kiran Majid Niaz Akhtar Muhammad Yousaf Khalid Mujassam Batoo Omar MAldossary Salman Naeem Khan | 2021 | Journal of Rare Earths2021，39，10： | 1 |
| 11 | Basal Application of Zinc to Improve Mung Bean Yield and Zinc-Grains-Biofortfication显示文摘Worldwide,the dietary deficiency of zinc(Zn)is prevailing in almost all arid and semi-arid regions.Zinc deficiency is not only the major constraint of lower yield,but also dietary Zn deficiency in cereals grains may cause increasing malnutrition and chronic health problems in human.Exogenous application of Zn through basal soil nutrition might be a useful option to recover Zn deficiency in mung bean.Therefore,field study was conducted to optimize the optimum level and method of Zn nutrition to enhance crop yield and Zn biofortification of mung bean through basal application.Zinc was applied at 0,5,10 and 15 kg/ha as basal application and side dressing,and in combination(50%basal application+50%side dressing).The results highlighted that Zn nutrition prominently improved the mung bean yield as compared with control(no Zn applied).The maximum grains yield and Zn concentration in grains were obtained where Zn was applied at 15 kg/ha as basal application as compared with all other combinations.Better improvement in grain yield was due to significant increase in more number of pods and grain size owing to well-developed root system,improved leaf area index and high chlorophyll contents in mung beans leaves.Amongst all applied Zn nutrition’s the basal application of Zn(15 kg/ha)was a viable option to get higher yield and Zn biofortification of mung bean. | Aroosa Kanwal Muhammad Bismillah Khan Mubshar Hussain Muhammad Naeem Muhammad Shahid Rizwan Muhammad Zafar-ul-Hye | 2020 | Phyton-International Journal of Experimental Botany2020，89，1： | 0 |
| 12 | Clinical relevance of circulating non-coding RNAs in metabolic diseases:Emphasis on obesity,diabetes,cardiovascular diseases and metabolic syndrome显示文摘Non-coding RNAs(ncRNAs)participate in the regulation of several cellular processes including transcription,RNA processing and genome rearrangement.The aberrant expression of ncRNAs is associated with several pathological conditions.In this review,we focused on recent information to elucidate the role of various regulatory ncRNAs i.e.,micro RNAs(miRNAs),circular RNAs(circRNAs)and long-chain non-coding RNAs(lncRNAs),in metabolic diseases,e.g.,obesity,diabetes mellitus(DM),cardiovascular diseases(CVD)and metabolic syndrome(MetS).The mechanisms by which ncRNAs participated in disease pathophysiology were also highlighted.miRNAs regulate the expression of genes at transcriptional and translational levels.circRNAs modulate the regulation of gene expression via miRNA sponging activity,interacting with RNA binding protein and polymerase II transcription regulation.lncRNAs regulate the expression of genes by acting as a protein decoy,miRNA sponging,miRNA host gene,binding to miRNA response elements(MRE)and the recruitment of transcriptional element or chromatin modifiers.We examined the role of ncRNAs in the disease pathogenesis and their potential role as molecular markers for diagnosis,prognosis and therapeutic targets.We showed the involvement of ncRNAs in the onset of obesity and its progression to MetS and CVD.miRNA-192,miRNA-122,and miRNA-221 were dysregulated in all these metabolic diseases.Other ncRNAs,implicated in at least three diseases include miRNA-15a,miRNA-26,miRNA-27a,miRNA-320,and miRNA-375.Dysregulation of ncRNAs increased the risk of development of DM and MetS and its progression to CVD in obese individuals.Hence,these molecules are potential targets to arrest or delay the progression of metabolic diseases. | Abdullahi Dandare Muhammad Jawad Khan Aisha Naeem Afrose Liaquat | 2023 | Genes & Diseases2023，10，6： | 0 |
| 13 | On Hiding Secret Information in Medium Frequency DCT Components Using Least Significant Bits Steganography显示文摘This work presents a new method of data hiding in digital images,in discrete cosine transform domain.The proposed method uses the least significant bits of the medium frequency components of the cover image for hiding the secret information,while the low and high frequency coefficients are kept unaltered.The unaltered low frequency DCT coefficients preserves the quality of the smooth region of the cover image,while no changes in the high DCT coefficient preserve the quality of the edges.As the medium frequency components have less contribution towards energy and image details,so the modification of these coefficients for data hiding results in high quality stego images.The distortion due to the changes in the medium frequency coefficients is insignificant to be detected by the human visual system.The proposed methods demonstrated a hiding capacity of 43:11%with the stego image quality of a peak signal to the noise ration of 36:3 dB,which is significantly higher than the threshold of 30 dB for a stego image quality.The proposed technique is immune to steganalysis and has proved to be highly secured against both spatial and DCT domain steganalysis techniques. | Sahib Khan M A Irfan Arslan Arif Syed Tahir Hussain Rizvi Asma Gul Muhammad Naeem Nasir Ahmad | 2019 | Computer Modeling in Engineering & Sciences2019，，3： | 0 |

| 15 | Strong interfacial charge transfer between hausmannite manganese oxide and alumina for efficient photocatalysis显示文摘Well crystalline manganese oxide(Mn_(3)O_(4))nanoparticles anchored on gamma alumina(γ-Al_(2)O_(3))have been successfully tailored via a proficient and cost effective chemical process as an efficient material for photo catalysis.XRD indicated the composite formation ofγ-Al_(2)O_(3) and hausmannite structure of Mn_(3)O_(4).SEM and TEM revealed that hetero structure of Mn_(3)O_(4)/γ-Al_(2)O_(3) exhibits an amalgam of aggregated nanoparticles and nanorods.XPS demonstrated the chemical states of binary nanocomposite.The band gap tuning has been performed withγ-Al_(2)O_(3) nanoparticles by assimilating hausmannite Mn_(3)O_(4) particles into flower like microstructure of Al_(2)O_(3).The photoluminescence spectra affirmed the enhancement in charge separation in Mn_(3)O_(4)/γ-Al_(2)O_(3) binary hybrid photocatalyst.The band gap becomes narrow with the increase in concentrations of Mn_(3)O_(4).The narrowing of band gap is concorded with crystalline domains of primary aggregated particles.To elucidate the mechanism of the photocatalytic activity linear sweep voltammetry was performed.The results showed that Mn_(3)O_(4)/γ-Al_(2)O_(3) nanocomposite revealed the enhancement in current density as compared to pureγ-Al_(2)O_(3) which confirmed the electron transfer from Mn_(3)O_(4) toγ-Al_(2)O_(3) through the interfacial potential gradient in conduction bands.The optimum concentration of 6.0%Mn_(3)O_(4)/γ-Al_(2)O_(3) for hybrid structure showed an excellent photocatalytic activity under visible light due to narrow band gap energy.High degree distribution of Mn_(3)O_(4) nano architects overlying onγ-Al_(2)O_(3) induces a significant synergic effect betweenγ-Al_(2)O_(3) and hausmannite phase of manganese oxide(Mn_(3)O_(4)).This strong interfacial contact betweenγ-Al_(2)O_(3) and Mn_(3)O_(4) endures the quick transfer of photo generated charge carriers across interface. | Aisha Kanwal Shamaila Sajjad Sajjad Ahmed Khan Leghari Muhammad Naeem Khan | 2021 | Chinese Journal of Chemical Engineering2021，34，5： | 0 |

| 17 | In vitro-in vivo correlation study on nimesulide loaded hydroxypropylmethylcellulose microparticles显示文摘This study involves mathematical simulation model such as in vitro-in vivo correlation(IVIVC) development for various extended release formulations of nimesulide loaded hydroxypropylmethylcellulose(HPMC) microparticles(M1,M2 and M3 containing 1,2,and 3 g HPMC,respectively and 1 g drug in each) having variable release characteristics.In vitro dissolution data of these formulations were correlated to their relevant in vivo absorption profiles followed by predictability worth analysis of these Level A IVIVC.Nimaran was used as control formulation to validate developed formulations and their respective models.The regression coefficients of IVIVC plots for M1,M2,M3 and Nimaran were 0.834 9,0.831 2,0.927 2 and 0.898 1,respectively.The internal prediction error for all formulations was within limits,i.e.,<10%.A good IVIVC was found for controlled release nimesulide loaded HPMC floating M3 microparticles.In other words,this mathematical simulation model is best fit for biowaiver studies which involves study parameters as those adopted for M3 because the value of its IVIVC regression coefficient is the closest to 1 as compared to M1 and M2. | Shujaat Ali KHAN Mahmood AHMAD Ghulam MURTAZA Muhammad Naeem AAMIR Rozina KOUSAR Fatima RASOOL Shahiq-u-ZAMAN | 2010 | 药学学报2010，45，6： | 0 |
| 18 | A Hybrid Duo-Deep Learning and Best Features Based Framework for Action Recognition显示文摘Human Action Recognition(HAR)is a current research topic in the field of computer vision that is based on an important application known as video surveillance.Researchers in computer vision have introduced various intelligent methods based on deep learning and machine learning,but they still face many challenges such as similarity in various actions and redundant features.We proposed a framework for accurate human action recognition(HAR)based on deep learning and an improved features optimization algorithm in this paper.From deep learning feature extraction to feature classification,the proposed framework includes several critical steps.Before training fine-tuned deep learning models–MobileNet-V2 and Darknet53–the original video frames are normalized.For feature extraction,pre-trained deep models are used,which are fused using the canonical correlation approach.Following that,an improved particle swarm optimization(IPSO)-based algorithm is used to select the best features.Following that,the selected features were used to classify actions using various classifiers.The experimental process was performed on six publicly available datasets such as KTH,UT-Interaction,UCF Sports,Hollywood,IXMAS,and UCF YouTube,which attained an accuracy of 98.3%,98.9%,99.8%,99.6%,98.6%,and 100%,respectively.In comparison with existing techniques,it is observed that the proposed framework achieved improved accuracy. | Muhammad Naeem Akbar Farhan Riaz Ahmed Bilal Awan Muhammad Attique Khan Usman Tariq Saad Rehman | 2022 | Computers, Materials & Continua2022，，11： | 0 |
| 19 | Dry matter degradation kinetics of selected tropical forage in Nili-Ravi buffalo and Cholistani cows at heifer and lactating stages using NorFor in situ standards显示文摘Current methods of ruminant ration formulation in Pakistan use foreign-based nutrient availability values.These values may not be optimal for all geographic areas,as variation in environment,agronomic factors,animal species,and diet characteristics may not be considered.The aim of present study was to establish a database of the chemical composition and dry matter degradation parameters of tropical forage commonly fed to ruminants in Pakistan and South Asian countries using Nili-Ravi buffalo and Cholistani cattle at heifer and lactating stages.Six cereal grain and four legume species were grown in 3 locations under standard agronomic conditions and sampled at booting and at 50%flowering stage for cereal and legumes,respectively.Dried and milled feeds were analyzed for chemical composition and in situ dry matter degradation parameters using 1 g samples in bags placed in the rumen of 2 Nili-Ravi buffalo heifers,2 lactating Nili-Ravi buffaloes,2 Cholistani heifers,and 2 lactating Cholistani cows.The forage family(cereal vs.legumes),species,and geographic location of growth significantly influenced(P<0.001)chemical composition and in situ degradation fractions.Animal species and developmental stage showed no effect on degradation fractions(P>0.05).Legume-by-heifer interactions significantly increased(P<0.05),and legume-by-lactating cow interaction tended(P=0.065),to increase the rate of degradation(Kd).The selected forages were degiaded to a similar extent independent of animal species or developmental stage,and legumes are degraded at higher rates and to a greater extent than are cereals.A moderately significant relationship between Kd and effective dry matter degradability(DMD)suggests tliat Kd co|iild be the single most important predictor of forage degi adability in the rumen. | Muhammad Naeem Tahir Zahid Khan Saima Zahid Kamran Fatma Inal | 2019 | Journal of Zoological Research2019，1，1： | 0 |
| 20 | Role of Organic Amendments to Mitigate Cd Toxicity and Its Assimilation in Triticum aestivum L.显示文摘In soil biota,higher and enduring concentration of heavy metals like cadmium(Cd)is hazardous and associated with great loss in growth,yield,and quality parameters of most of the crop plants.Recently,in-situ applications of eco-friendly stabilizing agents in the form of organic modifications have been utilized to mitigate the adverse effects of Cd-toxicity.This controlled experiment was laid down to appraise the imprints of various applied organic amendments namely poultry manure(PM),farmyard manure(FYM),and sugarcane press mud(PS)to immobilize Cd in polluted soil.Moreover,phytoavailability of Cd in wheat was also accessed under an alkaline environment.Results revealed that the addition of FYM(5–10 ton ha^(-1))in Cd-contaminated soil significantly increased germination rate,leaf chlorophyll content,plant height,spike length,biological and grain yield amongst all applied organic amendments.Moreover,the addition of FYM(5–10 ton ha^(-1))also reduced the phytoavailability of Cd by 73–85%in the roots,57–83%in the shoots,and 81–90%in grains of wheat crop.Thus,it is affirmed that incorporation of FYM(5–10 ton ha^(-1))performed better to enhance wheat growth and yield by remediating Cd.Thus,the application of FYM(5–10 ton ha^(-1))reduced the toxicity induced by Cd to plants by declining its uptake and translocation as compared to all other applied organic amendments to immobilize Cd under sandy alkaline polluted soil. | Tauqeer Ahmad Yasir Sobia Aslam Muhammad Shahid Rizwan Allah Wasaya Muhammad Ateeq Muhammad Naeem Khan Sikander Khan Tanveer Walid Soufan Basharat Ali Allah Ditta Arpna Kumari Ayman EL Sabagh | 2022 | Phyton-International Journal of Experimental Botany2022，91，11： | 0 |
