| 1 | 秸秆和地膜覆盖对黄土高原旱作小麦田土壤团聚体氮组分的影响显示文摘利用田间定位试验研究旱作农田不同覆盖措施对土壤团聚体氮组分的影响。基于黄土高原8年冬小麦覆盖定位试验,试验设置生育期秸秆覆盖(SM)、生育期地膜覆盖(PM)和无覆盖对照(CK)3个处理。采用干筛法测定团聚体分布特征及不同粒径团聚体中全氮(STN)、微生物量氮(MBN)和潜在可矿化氮(PNM)含量。结果表明:(1)与CK处理相比,2种覆盖处理均未在各粒径团聚体全氮含量有显著变化,但SM处理相较于PM处理提高了0-10 cm土层的1.00~0.25 mm粒径团聚体STN含量(12.88%,P<0.05)。(2)与CK处理相比,SM处理在0-10 cm土层中>2.00,2.00~1.00,<0.25 mm粒径团聚体MBN含量分别提高18.67%,24.05%,20.08%(P<0.05),且各粒径团聚体PNM含量分别提高35.13%,30.03%,42.88%(P<0.05);SM处理在10-20 cm土层中>2.00 mm粒径团聚体MBN含量提高23.02%(P<0.05),分别提高>2.00,2.00~1.00,<0.25 mm粒径团聚体PNM含量28.59%,31.31%,32.48%(P<0.05)。(3)PM处理较CK处理提高0-10 cm土层中<0.25 mm粒径团聚体PNM含量(32.34%,P<0.05)。(4)微团聚体(<0.25 mm)氮组分含量均高于大团聚(>0.25 mm)氮组分含量,但大团聚体氮组分贡献率为81.88%~87.66%。可见,SM处理可提高土壤表层大团聚体氮组分的贡献率,使更多的氮素储存在大团聚体中,而PM处理对团聚体氮素贡献率的影响作用较小。总体而言,与CK和PM处理相比,SM处理可提高总土壤氮组分含量,提高微团聚体和大团聚体氮组分含量,使更多的氮储存在大团聚体中,促进土壤氮素周转。 | 张少宏 付鑫 IHSAN Muhammad 刘文清 王俊 | 2020 | 水土保持学报2020，34，1： | 14 |

| 5 | Preliminary study of adsorption behavior of bovine serum albumin(BSA) protein and its effect on antibacterial and corrosion property of Ti-3Cu alloy显示文摘The adsorption behavior, antibacterial, and corrosion properties of a Ti-3 Cu alloy were studied in a phosphate-buffered saline solution containing 0, 1, 3, and 6 gL^(-1) bovine serum albumin protein at 37℃ and pH = 7.4(±0.2). The protein adsorption behavior was examined via cyclic voltammetry, secondary ions mass spectroscopy(SIMS), and angle-resolved X-ray photoelectron spectroscopy(ARXPS). The corrosion property was analyzed by the open circuit potential(OCP), potentiodynamic polarization(PD),and electrochemical impedance spectroscopy(EIS) examinations. The antibacterial test was conducted according to the GB/T 21510 China Standard. It was observed that the surface charge density(QA DS) was directly proportional to the amount of the adsorbed BSA protein, signifying that the protein adsorption was accompanied by the charge transfer, pointing to chemisorptions phenomena. BSA amino groups and other organic species were observed in the surface analysis examinations. It was shown that the formation of barrier complexes between the TiO_(2) oxide-layer and PBS solution resulted in decreasing the release of Cu-ions, which consequently reduced the antibacterial activity. On the other hand, these barrier complexes improved the corrosion resistance by increasing the charge transfer resistance and double-layer capacitance of the Ti-3 Cu alloy. | Muhammad Ali Siddiqui Ihsan Ullah Hui Liu Shuyuan Zhang Ling Ren Ke Yang | 2021 | Journal of Materials Science & Technology2021，，21： | 1 |
| 6 | Novel biallelic loss-of-function mutations in CFAP43 cause multiple morphological abnormalities of the sperm flagellum in Pakistani families显示文摘Multiple morphological abnormalities of the sperm flagella(MMAF)is a specific type of asthenoteratozoospermia,presenting with multiple morphological anomalies in spermatozoa,such as absent,bent,coiled,short,or irregular caliber flagella.Previous genetic studies revealed pathogenic mutations in genes encoding cilia and flagella-associated proteins(CFAPs;e.g.,CFAP43,CFAP44,CFAP65,CFAP69,CFAP70,and CFAP251)responsible for the MMAF phenotype in infertile men from different ethnic groups.However,none of them have been identified in infertile Pakistani males with MMAF.In the current study,two Pakistani families with MMAF patients were recruited.Whole-exome sequencing(WES)of patients and their parents was performed.WES analysis reflected novel biallelic loss-of-function mutations in CFAP43 in both families(Family 1:ENST00000357060.3,p.Arg300Lysfs*22 and p.Thr526Serfs*43 in a compound heterozygous state;Family 2:ENST00000357060.3,p.Thr526Serfs*43 in a homozygous state).Sanger sequencing further confirmed that these mutations were segregated recessively in the families with the MMAF phenotype.Semiquantitative reverse-transcriptase polymerase chain reaction(qRT-PCR)was carried out to detect the effect of the mutation on mRNA of the affected gene.Previous research demonstrated that biallelic loss-of-function mutations in CFAP43 accounted for the majority of all CFAP43-mutant MMAF patients.To the best of our knowledge,this is the first study to report CFAP43 biallelic loss-of-function mutations in a Pakistani population with the MMAF phenotype.This study will help researchers and clinicians to understand the genetic etiology of MMAF better. | Ihsan Khan Basit Shah Sobia Dil Nadeem Ullah Jian-Teng Zhou Da-Ren Zhao Yuan-Wei Zhang Xiao-Hua Jiang Ranjha Khan Asad Khan Haider Ali Muhammad Zubair Wasim Shah Huan Zhang Qing-Hua Shi | 2021 | Asian Journal of Andrology2021，23，6： | 1 |

| 10 | Machine Learning-Enabled Power Scheduling in IoT-Based Smart Cities显示文摘Recent advancements in hardware and communication technologies have enabled worldwide interconnection using the internet of things(IoT).The IoT is the backbone of smart city applications such as smart grids and green energy management.In smart cities,the IoT devices are used for linking power,price,energy,and demand information for smart homes and home energy management(HEM)in the smart grids.In complex smart gridconnected systems,power scheduling and secure dispatch of information are the main research challenge.These challenges can be resolved through various machine learning techniques and data analytics.In this paper,we have proposed a particle swarm optimization based machine learning algorithm known as a collaborative execute-before-after dependency-based requirement,for the smart grid.The proposed collaborative execute-before-after dependencybased requirement algorithm works in two phases,analysis and assessment of the requirements of end-users and power distribution companies.In the rst phases,a xed load is adjusted over a period of 24 h,and in the second phase,a randomly produced population load for 90 days is evaluated using particle swarm optimization.The simulation results demonstrate that the proposed algorithm performed better in terms of percentage cost reduction,peak to average ratio,and power variance mean ratio than particle swarm optimization and inclined block rate. | Nabeela Awan Salman Khan Mohammad Khalid Imam Rahmani Muhammad Tahir Nur Alam MD Ryan Alturki Ihsan Ullah | 2021 | Computers, Materials & Continua2021，，5： | 0 |
| 11 | Effect of Active Zeolite in the Pyrolysis of Polypropylene and Low Density Polyethylene Types of Plastic Waste显示文摘Plastic is a basic need for humans,but it has also caused big problems for the environment.Then,the purpose of this study was to determine the effect of the type of plastic and the addition of a zeolite catalyst on the oil yield from the pyrolysis of plastic waste.The research stages were natural zeolite activation,pyrolysis reactor settings,pyrolysis of plastic waste(PP and LDPE types),and characterization.The results showed that the used natural zeolite had a mordenite phase and activated natural zeolite had a higher Si/Al ratio than the inactivated one.The addition of a zeolite catalyst had an effect on the produced yield.The yields of oil from plastic waste pyrolysis with zeolite catalyst for PP and LDPE plastics were about 75.9 and 76.9 w/w,respectively.The results of the GCMS analysis showed that the compounds of the pyrolysis oil were thought to be from the alkanes,cycloalkanes,alkenes,carboxylic acids with aromatic rings,and ketones.The results of the GC-MS test showed that the uncatalyzed pyrolysis product consists of compounds with a range of C5-C11 carbon chains.Meanwhile,the ranges of pyrolysis products with active zeolite catalyst were C6-C24 carbon chains. | Aman Santoso Amirotus Sholikhah Sumari Sumari Muhammad Roy Asrori Anugrah Ricky Wijaya Rini Retnosari Ihsan Budi Rachman | 2022 | Journal of Renewable Materials2022，10，11： | 0 |
| 12 | Bacterial Spectrum and Antimicrobial Profile of Pediatric Blood Stream Infection at a Tertiary Care Hospital in Pakistan显示文摘Objectives Blood stream infections(BSIs)are the main cause of morbidity and mortality in children worldwide.The present study was carried out to determine the prevalence of BSI with a focus on the identification of the causative agent of BSI,and to further evaluate the antibiotic susceptibility profile of the causing bacterial pathogens.Methods A cross-section study was carried out at the tertiary care hospital in Peshawar,Pakistan from January to December,2018.Blood samples were collected in BACTEC™botdes and standard microbiological protocols were applied for the isolation and identification of bacterial strains.The antibiotic susceptibility tests were performed using disc diffusion method as per the 2014 guideline of Clinical Laboratory Standard Institute(CLSI).Results Of 567 blood cultures in total,111(19.6%)were positive for BSI.Male children were 64%(71/111)and female children were 36%(40/111).For the causative predominant group of microorganisms,Gramnegative bacteria were identified in 79(71.1%)isolates,and Gram-positive bacteria in 32(28.9%)isolates.The common bacteria of isolates were S.typhi(n=35,31.5%),E.coli(n=19,17.1%),S.aureus(n=18,16.2%),K.pneumonia(n=12,10.8%),and Enterococcus species(n=7,6.3%).The 36.7%(29/79)isolates of Gram-negative bacteria were ESBL producers,and 61.1%(11/18)of S.aureus isolates were methicillin resistant.Overall,72.9%isolates were multidrug resistant.Conclusions Gram-negative bacteria were the main cause of pediatric BSIs,where the predominant microorganism was S.卯hi.Remarkably,majority of the S.typhi isolates were resistant to ciprofloxacin. | Anees Muhammad Sadiq Noor Khan Tahir Jamal Irshad Ul Haq Abdul Jabbar Ihsan Ali | 2020 | Chinese Medical Sciences Journal2020，35，4： | 0 |
| 13 | Optimized Mechanical Properties,Corrosion Resistance and Bactericidal Ability of Ti-15Zr-xCu Biomedical Alloys During Aging Treatment显示文摘The effects of different aging conditions on the microstructure,strength,corrosion resistance,cytotoxicity and antibacterial ability of Ti-15Zr-xCu(3≤x≤7,wt%)(TZC)alloys were systematically investigated.Microstructural evolution and behavior were analyzed by X-ray diffraction(XRD)patterns and scanning electron microscopy with energy-dispersive spectroscopy(SEM-EDS),while potentiodynamic polarization technique was employed to characterize the corrosion response of the alloys after solution-treatment and aging(STA).High-temperature aging at 660℃ for 4 h(660-4)gave the best combination of properties by enabling significant precipitation of the Cu-rich Ti_(2)Cu and Zr_(2)Cu compounds,and mild formation of the Zr_(7)Cu_(10) secondary phase.The high kinetics at this condition was beneficial to the complete precipitation and more homogeneous distribution of the intermetallic particles.These led to the inhibition of dislocation movements and allowed for significantly improved mechanical strengths with added ductility,availability of more Cu ions for the desired oligodynamic activity without evoking cytotoxicity,better corrosion resistance and very high antibacterial ability(over 99.5%),thus improving the overall properties of the TZC alloys for biomedical applications. | Sharafadeen Kunle Kolawole Ling Ren Muhammad Ali Siddiqui Ihsan Ullah Hai Wang Shuyuan Zhang Ji Zhang Ke Yang | 2022 | Acta Metallurgica Sinica(English Letters)2022，35，2： | 0 |
| 14 | 怀豆和黑麦草绿肥残体还田对旱地土壤温室气体排放的影响显示文摘以怀豆和黑麦草两种绿肥为对象,分别进行了为期63 d的不同绿肥残体还田量和残体混合比例室内培养试验,其中绿肥残体还田量试验分别设0、1、2、4、6 t·hm^(-2)共5个水平;残体混合比例试验设100%怀豆、25%怀豆+75%黑麦草、50%怀豆+50%黑麦草、75%怀豆+25%黑麦草和100%黑麦草共5个处理,还田量均为4 t·hm^(-2)。采用气相色谱法观测了培养期间土壤温室气体(CO_(2)、N_(2) O、CH_(4))通量变化。结果表明:(1)与未添加绿肥残体相比,绿肥残体还田土壤CO_(2)累积排放通量提高了11.3%~80.2%,土壤N_(2) O排放提高了15.8%~51.1%,综合增温潜势(GWP)提高了11.9%~79.4%(P<0.05)。随绿肥残体还田量的增加,土壤CO_(2)排放通量和综合增温潜势(GWP)均呈线性增加,土壤CH_(4)吸收通量则呈线性下降趋势,而土壤N_(2) O排放通量呈现先增后减趋势,并在还田量约为3 t·hm^(-2)时达到最大。相同还田量下添加黑麦草残体较怀豆残体具有更高的土壤CO_(2)排放和CH_(4)吸收,而添加怀豆残体较黑麦草残体显著促进了土壤N_(2) O排放;(2)土壤温室气体累计通量与绿肥残体混合物中黑麦草比例存在线性相关,随黑麦草添加比例的提高,土壤CO_(2)排放通量显著增加了5.8%~19.7%(P<0.05),GWP显著增加了5.3%~17.7%(P<0.05),而N_(2) O排放通量显著下降了11.2%~41.5%(P<0.05),CH_(4)吸收通量则显著下降了13.4%~50.9%(P<0.05)。综合来看,选择非豆科作物比例较低的绿肥残体,并以较低生物量进行还田,能在保持低GWP的同时获得生态效益。 | 谈光野 IHSAN Muhammad 杨彩迪 王俊 | 2024 | 干旱地区农业研究2024，42，2： | 0 |
| 15 | Hydrological response under CMIP6 climate projection in Astore River Basin,Pakistan显示文摘Climate change strongly influences the available water resources in a watershed due to direct linkage of atmospheric driving forces and changes in watershed hydrological processes.Understanding how these climatic changes affect watershed hydrology is essential for human society and environmental processes.Coupled Model Intercomparison Project phase 6(CMIP6)dataset of three GCM's(BCC-CSM2-MR,INM-CM5-0,and MPIESM1-2-HR)with resolution of 100 km has been analyzed to examine the projected changes in temperature and precipitation over the Astore catchment during 2020-2070.Bias correction method was used to reduce errors.In this study,statistical significance of trends was performed by using the Man-Kendall test.Sen's estimator determined the magnitude of the trend on both seasonal and annual scales at Rama Rattu and Astore stations.MPI-ESM1-2-HR showed better results with coefficient of determination(COD)ranging from 0.70-0.74 for precipitation and 0.90-0.92 for maximum and minimum temperature at Astore,Rama,and Rattu followed by INM-CM5-0 and BCC-CSM2-MR.University of British Columbia Watershed model was used to attain the future hydrological series and to analyze the hydrological response of Astore River Basin to climate change.Results revealed that by the end of the 2070s,average annual precipitation is projected to increase up to 26.55%under the SSP1-2.6,6.91%under SSP2-4.5,and decrease up to 21.62%under the SSP5-8.5.Precipitation also showed considerable variability during summer and winter.The projected temperature showed an increasing trend that may cause melting of glaciers.The projected increase in temperature ranges from-0.66℃ to 0.50℃,0.9℃ to 1.5℃ and 1.18℃ to 2℃ under the scenarios of SSP1-2.6,SSP2-4.5 and SSP5-8.5,respectively.Simulated streamflows presented a slight increase by all scenarios.Maximum streamflow was generated under SSP5-8.5 followed by SSP2-4.5 and SSP1-2.6.The snowmelt and groundwater contributions to streamflow have decreased whereas rainfall and glacier melt components have increased on the other hand.The projected streamflows(2020-2070)compared to the control period(1990-2014)showed a reduction of 3%-11%,2%-9%,and 1%-7%by SSP1-2.6,SSP2-4.5,and SSP5-8.5,respectively.The results revealed detailed insights into the performance of three GCMs,which can serve as a blueprint for regional policymaking and be expanded upon to establish adaption measures. | Zeshan ALI Mudassar IQBAL Ihsan Ullah KHAN Muhammad Umer MASOOD Muhammad UMER Muhammad Usama Khan LODHI Muhammad Atiq Ur Rehman TARIQ | 2023 | Journal of Mountain Science2023，20，8： | 0 |
| 16 | Optimal Deep Reinforcement Learning for Intrusion Detection in UAVs显示文摘In recent years,progressive developments have been observed in recent technologies and the production cost has been continuously decreasing.In such scenario,Internet of Things(IoT)network which is comprised of a set of Unmanned Aerial Vehicles(UAV),has received more attention from civilian tomilitary applications.But network security poses a serious challenge to UAV networks whereas the intrusion detection system(IDS)is found to be an effective process to secure the UAV networks.Classical IDSs are not adequate to handle the latest computer networks that possess maximumbandwidth and data traffic.In order to improve the detection performance and reduce the false alarms generated by IDS,several researchers have employed Machine Learning(ML)and Deep Learning(DL)algorithms to address the intrusion detection problem.In this view,the current research article presents a deep reinforcement learning technique,optimized by BlackWidow Optimization(DRL-BWO)algorithm,for UAV networks.In addition,DRL involves an improved reinforcement learning-based Deep Belief Network(DBN)for intrusion detection.For parameter optimization of DRL technique,BWO algorithm is applied.It helps in improving the intrusion detection performance of UAV networks.An extensive set of experimental analysis was performed to highlight the supremacy of the proposed model.From the simulation values,it is evident that the proposed method is appropriate as it attained high precision,recall,F-measure,and accuracy values such as 0.985,0.993,0.988,and 0.989 respectively. | V.Praveena A.Vijayaraj P.Chinnasamy Ihsan Ali Roobaea Alroobaea Saleh Yahya Alyahyan Muhammad Ahsan Raza | 2022 | Computers, Materials & Continua2022，，2： | 0 |
| 17 | Machine Learning-based Stable P2P IPTV Overlay显示文摘Live video streaming is one of the newly emerged services over the Internet that has attracted immense interest of the service providers.Since Internet was not designed for such services during its inception,such a service poses some serious challenges including cost and scalability.Peer-to-Peer(P2P)Internet Protocol Television(IPTV)is an application-level distributed paradigm to offer live video contents.In terms of ease of deployment,it has emerged as a serious alternative to client server,Content Delivery Network(CDN)and IP multicast solutions.Nevertheless,P2P approach has struggled to provide the desired streaming quality due to a number of issues.Stability of peers in a network is one of themajor issues among these.Most of the existing approaches address this issue through older-stable principle.This paper first extensively investigates the older-stable principle to observe its validity in different scenarios.It is observed that the older-stable principle does not hold in several of them.Then,it utilizes machine learning approach to predict the stability of peers.This work evaluates the accuracy of severalmachine learning algorithms over the prediction of stability,where the Gradient Boosting Regressor(GBR)out-performs other algorithms.Finally,this work presents a proof-of-concept simulation to compare the effectiveness of older-stable rule and machine learning-based predictions for the stabilization of the overlay.The results indicate that machine learning-based stability estimation significantly improves the system. | Muhammad Javid Iqbal Ihsan Ullah Muhammad Ali Atiq Ahmed Waheed Noor Abdul Basit | 2022 | Computers, Materials & Continua2022，，6： | 0 |
| 18 | A recurrent homozygous missense mutation in CCDC103 causes asthenoteratozoospermia due to disorganized dynein arms显示文摘Asthenoteratozoospermia is one of the most severe types of qualitative sperm defects.Most cases are due to mutations in genes encoding the components of sperm flagella,which have an ultrastructure similar to that of motile cilia.Coiled-coil domain containing 103(CCDC103)is an outer dynein arm assembly factor,and pathogenic variants of CCDC103 cause primary ciliary dyskinesia(PCD).However,whether CCDC103 pathogenic variants cause severe asthenoteratozoospermia has yet to be determined.Whole-exome sequencing(WES)was performed for two individuals with nonsyndromic asthenoteratozoospermia in a consanguineous family.A homozygous CCDC103 variant segregating recessively with an infertility phenotype was identified(ENST00000035776.2,c.461A>C,p.His154Pro).CCDC103 p.His154Pro was previously reported as a high prevalence mutation causing PCD,though the reproductive phenotype of these PCD individuals is unknown.Transmission electron microscopy(TEM)of affected individuals’spermatozoa showed that the mid-piece was severely damaged with disorganized dynein arms,similar to the abnormal ultrastructure of respiratory ciliary of PCD individuals with the same mutation.Thus,our findings expand the phenotype spectrum of CCDC103 p.His154Pro as a novel pathogenic gene for nonsyndromic asthenospermia. | Muhammad Zubair Ranjha Khan Ao Ma Uzma Hameed Mazhar Khan Tanveer Abbas Riaz Ahmad Jian-Teng Zhou Wasim Shah Ansar Hussain Nisar Ahmed Ihsan Khan Khalid Khan Yuan-Wei Zhang Huan Zhang Li-Min Wu Qing-Hua Shi | 2022 | Asian Journal of Andrology2022，24，3： | 0 |
| 19 | Adaptive Power Control Aware Depth Routing in Underwater Sensor Networks显示文摘Underwater acoustic sensor network(UASN)refers to a procedure that promotes a broad spectrum of aquatic applications.UASNs can be practically applied in seismic checking,ocean mine identification,resource exploration,pollution checking,and disaster avoidance.UASN confronts many difficulties and issues,such as low bandwidth,node movements,propagation delay,3D arrangement,energy limitation,and high-cost production and arrangement costs caused by antagonistic underwater situations.Underwater wireless sensor networks(UWSNs)are considered a major issue being encountered in energy management because of the limited battery power of their nodes.Moreover,the harsh underwater environment requires vendors to design and deploy energy-hungry devices to fulfil the communication requirements and maintain an acceptable quality of service.Moreover,increased transmission power levels result in higher channel interference,thereby increasing packet loss.Considering the facts mentioned above,this research presents a controlled transmission power-based sparsity-aware energy-efficient clustering in UWSNs.The contributions of this technique is threefold.First,it uses the adaptive power control mechanism to utilize the sensor nodes’battery and reduce channel interference effectively.Second,thresholds are defined to ensure successful communication.Third,clustering can be implemented in dense areas to decrease the repetitive transmission that ultimately affects the energy consumption of nodes and interference significantly.Additionally,mobile sinks are deployed to gather information locally to achieve the previously mentioned benefits.The suggested protocol is meticulously examined through extensive simulations and is validated through comparison with other advanced UWSN strategies.Findings show that the suggested protocol outperforms other procedures in terms of network lifetime and packet delivery ratio. | Ghufran Ahmed Saiful Islam Ihsan Ali Isra Adil Hayder Abdelmuttlib Ibrahim Abdalla Ahmed Muhammad Talha Sultan S.Alshamrani Ag Asri Ag Ibrahim | 2021 | Computers, Materials & Continua2021，，10： | 0 |
