| 1 | Geometric Mean Decomposition Based Hybrid Precoding for Millimeter-Wave Massive MIMO显示文摘Hybrid precoding can reduce the number of required radio frequency(RF)chains in millimeter-Wave(mmWave) massive MIMO systems. However, existing hybrid precoding based on singular value decomposition(SVD) requires the complicated bit allocation to match the different signal-to-noise-ratios(SNRs) of different sub-channels. In this paper,we propose a geometric mean decomposition(GMD)-based hybrid precoding to avoid the complicated bit allocation. Specifically,we seek a pair of analog and digital precoders sufficiently close to the unconstrained fully digital GMD precoder. To achieve this, we fix the analog precoder to design the digital precoder, and vice versa. The analog precoder is designed based on the orthogonal matching pursuit(OMP) algorithm, while GMD is used to obtain the digital precoder. Simulations show that the proposed GMD-based hybrid precoding achieves better performance than the conventional SVD-based hybrid precoding with only a slight increase in complexity. | Tian Xie Linglong Dai Xinyu Gao Muhammad Zeeshan Shakir Jianjun Li | 2018 | China Communications2018，15，5： | 17 |
| 2 | Farmers' Perception and Awareness and Factors Affecting Awareness of Farmers Regarding Crop Insurance as a Risk Coping Mechanism Evidence from Pakistan显示文摘This study has been conducted in three districts of Punjab Province namely, Dera Ghazi Khan, Rajan Pur and Bahawalpur of Pakistan. The study showed the results of a survey of 300 farmers which was organized to assess awareness level of farmers regarding crop insurance, factors affecting the awareness level among farmers and the perception of farmers about crop insurance. Based on exploratory research work upon the responses of farmers, the average and standard deviation were calculated. Probit model was applied to explore the factors affecting the awareness level of farmers. SPSS was used for the analysis of the collected data. The results revealed that out of 300 farmers, 184 farmers were aware with crop insurance and rests of the 116 farmers were not aware. Banks and E-media were found to be the two most important sources of the awareness for the respondent farmers. In the study area, the climatic risks were reported as the most severe risks faced by the farmers. The results also revealed the existence of negative perceptions of the farmers about crop insurance i.e. farmers perceived crop insurance as a kind of tax and they believed premium was so high that it was out of range of poor farmers and only large scale farmers could afford it. Results obtained by applying Probit model revealed that 'education' and 'previously availed agricultural credit' were the two most important factors which affected the awareness of the farmers regarding crop insurance. | Sidra Ghazanfar Zhang Qi-wen Muhammad Abdullah Zeeshan Ahmad Majid Lateef | 2015 | Journal of Northeast Agricultural University(English Edition)2015，22，1： | 9 |
| 3 | Enhancing through-plane thermal conductivity of fluoropolymer composite by developing in situ nano-urethane linkage at graphene–graphene interface显示文摘Attributed to the intense development and complexity in electronic devices,energy dissipation is becoming more essential nowadays.The carbonaceous materials particularly graphene(Gr)-based thermal interface materials(TIMs)are exceptional in heat management.However,because of the anisotropic behavior of Gr in composites,the TIMs having outstanding through-plane thermal conductivity(┴TC)are needed to fulfill the upcoming innovation in numerous devices.In order to achieve this,herein,nano-urethane linkage-based modified Gr and carbon fibers architecture termed as nanourethane linkage(NUL)-Gr/carbon fibers(CFs)is fabricated.Wherein,toluene diisocyanate is utilized to develop a novel but simple NUL to shape a new interface between graphene sheets.Interestingly,the prepared composite of NUL-Gr/CFs with polyvinylidene fluoride matrix shows outstanding performance in heat management.Owing to the unique structure of NUL-Gr/CFs,an unprecedented value of┴TC(~7.96 W·m^–1·K^–1)is achieved at a low filler fraction of 13.8 wt.%which translates into an improvement of^3,980%of pristine polymer.The achieved outcomes elucidate the significance of the covalent interaction between graphene sheets as well as strong bonding among graphene and matrix in the composites and manifest the potential of proposed NUL-Gr/CFs architecture for practical applications. | Muhammad Maqbool Haichang Guo Akbar Bashir Ali Usman Adeel YAbid Guansong He Yanjuan Ren Zeeshan Ali Shulin Bai | 2020 | Nano Research2020，13，10： | 3 |
| 4 | Investigating the impact of Glyoxal retrieval from MAX-DOAS observations during haze and non-haze conditions in Beijing显示文摘This study presents the Multi Axis Differential Optical Absorption Spectroscopy(MAXDOAS) measurements for Glyoxal(CHOCHO) in Beijing, China(39.95°N, 116.32°E). CHOCHO is the smallest compound of di-carbonyl group. As a primary sink of CHOCHO, its photolysis with NOx(oxides of nitrogen) results in the production of tropospheric ozone. Therefore,the focus of CHOCHO DOAS measurements is increasing in trend. We did the measurements from 09 May 2017 to 09 September 2017. The study was conducted to compare different retrieval settings in order to reveal best DOAS fit settings for CHOCHO;furthermore, effect of haze and non-haze days on CHOCHO concentration was examined.The root mean square of residual and Differential Slant Column density(dSCD) error was reduced when measurements were done with lower wavelength limit around 432–438 nm and upper intervals around 455–460 nm. Thus, lower wavelength intervals around432–438 nm and upper intervals around 457–460 nm were best for the retrieval of dSCDs for CHOCHO. Meteorological conditions like haze or non-haze days did not have significant effect on DOAS fit parameters. The CHOCHO vertical column densities range from 1.33 E +14 to 9.77 E + 14 molecules/cm2 during the study period with average of 6.16 E +14 molecules/cm2. The results indicated that during haze days CHOCHO concentration was higher because of lower rate of photolysis and atmospheric oxidation potential. Our results did not show any significant weekend effect on CHOCHO atmospheric concentration. | Zeeshan Javed Cheng Liu Muhammad Fahim Khokhar Chengzhi Xing Wei Tan Muhammad Ahmed Subhani Abdul Rehman Aimon Tanvir | 2019 | Journal of Environmental Sciences2019，31，6： | 3 |

| 6 | Current controversies and advances in the management of pancreatic adenocarcinoma显示文摘Pancreatic adenocarcinoma is a lethal disease with a mortality rate that has not significantly improved over decades.This is likely due to several challenges unique to pancreatic cancer.Most patients with pancreatic cancer are diagnosed at a late stage of disease due to the lack of specific symptoms prompting an early investigation.A small subset of patients who are diagnosed at an early stage have a better chance at survival with curative surgical resection,but most patients still succumb to the disease in a few years.The dismal overall prognosis is due to suspected micro-metastasis at an early stage.Due to this reason,there is a recent interest in treating all patients with pancreatic cancers with systemic therapy upfront(including the ones that are surgically resectable).This approach is still not the standard of care due to the lack of robust prospective data available.Recent advancements in treatment regimens of chemotherapy,radiation and immunotherapy have improved the overall short-term survival but the long-term survival still remains poor.Novel approaches in diagnosis and treatment have shown promise in clinical studies but long-term clinical data is lacking.The following manuscript presents an overview of the epidemiology,diagnosis,staging,recent advances,novel approaches and controversies in the management of pancreatic adenocarcinoma. | Muhammad Shehroz Zeeshan Zeeshan Ramzan | 2021 | World Journal of Gastrointestinal Oncology2021，13，6： | 2 |
| 7 | New Era: Endoscopic treatment options in obesity–a paradigm shift显示文摘The prevalence of obesity continues to rise,and along with it comes a multitude of health-related consequences.The healthcare community has consistently struggled with providing treatment options to obese patients,in part due to the reluctance of patients in pursuing the more effective(yet invasive)surgical approaches such as sleeve gastrectomy and Rou-en-Y gastric bypass.On the other hand,the less invasive approach such as lifestyle/behavioral interventions and pharmacotherapy(Orlistat,Phenteramine,Phentermine/Topiramate,Locaserin,Naltrexon/Buproprion,and Liraglutide)have very limited efficacy,especially in the morbidly obese patients.Despite our best efforts,the epidemic of obesity continues to rise and pose enormous costs on our healthcare system and society.Bariatric endoscopy is an evolving field generated to combat this epidemic through minimally invasive techniques.These procedures can be performed in an ambulatory setting,are potentially reversible,repeatable,and pose less complications than their invasive surgical counterparts.These modalities are designed to alter gut metabolism by means of space occupation,malabsorption,or restriction.In this review we will discuss different bariatric endoscopic options(such as intragastric balloons,endoscopic sleeve gastroplasty,endoscopic aspiration therapies and gastrointestinal bypass sleeves),their advantages and disadvantages,and suggest a new paradigm where providers may start incorporating this modality in their treatment approach for obese patients. | Jason Glass Ahson Chaudhry Muhammad S Zeeshan Zeeshan Ramzan | 2019 | World Journal of Gastroenterology2019，25，32： | 1 |
| 8 | Adaptation of Drosophila species to climate change——A literature review since 2003显示文摘Global climate warming has been exerting impacts on agricultural pests. Pests also take some strategies to adapt to climate change. Understanding such adaptation could benefit more accurate predictions and integrated management of pest. However, adaptation to climate change has not been widely investigated in agricultural pests but has been well documented in model species, Drosophila, and reviewed by Hoffmann before 2003. To provide recent progress and references for agricultural entomologists who interested in thermal biology, here we have reviewed literatures since 2003 about adaptation to temperature changes under climate change. We mainly summarized thermal adaptation of Drosophila(especially to high temperatures) from three aspects, behaviors, plastic responses and micro-evolution and discussed how Drosophila increases their heat tolerance through these three mechanisms. Finally, we summarized the measures of thermotolerance and concluded the main progress in recent decade about the behavioral thermoregulation, mortality risks driven by limited evolutionary and plastic response under climate change, geographic distribution based on basal rather than plastic thermotolerance. We propose future work focus on better understanding adaptation of organisms including agricultural pests to climate change. | XUE Qi Muhammad Zeeshan Majeed ZHANG Wei MA Chun-sen | 2019 | Journal of Integrative Agriculture2019，18，4： | 1 |

| 11 | Breeding for pre-harvest sprouting resistance in bread wheat under rainfed conditions显示文摘Pre-harvest sprouting in wheat is the germination of seeds within the spikes when rains occur after or during grain ripening, which occurs commonly in the barani tract of Pakistan. Therefore, 10 cultivars and five advanced lines of spring bread wheat were evaluated for pre-harvest sprouting resistance. After natural rainfall,seeds were immediately collected from the wet spikes and tested for germinating ability. Three different germination tests were applied to hand-threshed seed:(1) spikes threshed on the day of sampling and germination tested immediately,(2) spikes threshed on the day of sampling and germination tested 1 week later, and(3) spikes threshed 1 week after sampling and germination test immediately after threshing. Seeds and spikes kept for 1 week were place on blotting paper at room temperature.Cultivars BARS-09, 09 FJ17, Doukkala-12, NARC-09 and Ouassou-20 exhibited higher sprouting resistance while other genotypes were susceptible to pre-harvest sprouting in each of the three tests. A diallel crossing was conducted with six susceptible and two resistant genotypes to assess the genetic behavior of pre-harvest sprouting resistance.The combining ability(CA) demonstrated a higher proportion of additive genetic effects for sprouting resistance, because of higher variance of general and specific CA for both parameters under study. Doukkala-12 and BARS-09 showed increased pre-harvest sprouting resistance in their F1 descendants. | Muhammad ZEESHAN Waheed ARSHAD Muhammad Imran KHAN Shiraz ALI Ali NAWAZ Amina BATOOL Muhammad TARIQ Muhammad Imran AKRAM Muhammad Amjad ALI | 2018 | Frontiers of Agricultural Science and Engineering2018，5，2： | 1 |
| 12 | Changes in Germination and Seedling Traits of Sesame under Simulated Drought显示文摘Drought is considered one of the leading abiotic constraints to agricultural crop production globally.Present study was conducted to assess the effects of different drought treatments(viz.Control,10%PEG,and 20%PEG)on seed germination,germination indices,seedling traits,and drought tolerance indices of sesame.Our results showed that maximum reduction in the studied parameters was observed at higher PEG concentration(i.e.,20%PEG).As compared to control,the drought treatments viz.10%and 20%PEG decreased the values for germination indices,such as germination percentage,coefficient of variation of germination time,germination index,and seedling vigor index.Similarly,for seedling traits,the values were decreased for root length,shoot length,root shoot ratio,root fresh weight,shoot fresh weight,root dry weight and shoot dry weight under 10%and 20%PEG treatments significantly in comparison with control.Furthermore,relative to control,the values for drought tolerance indices,such as germination drought tolerance index,root length drought tolerance index,shoot length drought tolerance index,total seedling length drought tolerance index,root fresh weight drought tolerance index,shoot fresh weight drought tolerance index,total fresh weight drought tolerance index,root dry weight drought tolerance index,shoot dry weight drought tolerance index and total dry weight drought tolerance index were also reduced under 10%and 20%PEG treatments,respectively.Our results confirms that drought impact on seed germination and seedling traits could be quantified by using different indices which can further help to design drought adaptation and mitigation strategies.Based on these results it can be concluded that germination indices,seedling traits,and drought tolerance indices have great potential to simulate drought stress impacts on different crop traits thus they should be used in all kinds of stress related studies. | Mukhtar Ahmed Ahmed M.S.Kheir Muhammad Zeeshan Mehmood Shakeel Ahmad Mirza Hasanuzzaman | 2022 | Phyton-International Journal of Experimental Botany2022，91，4： | 1 |
| 13 | Outcomes after stenting for malignant large bowel obstruction without radiologist support显示文摘AIM:To assess outcomes after colonic stent insertion for obstructing colorectal malignancies performed by an endoscopist without radiologist support.METHODS:This is a retrospective study of all stents inserted by a single surgeon in a District General Hospital over an eight year period.All stents were inserted for patients with acute large bowel obstruction secondary to a malignant colorectal pathology either for palliation or as a bridge to surgery.Procedures were performed by a single surgeon endoscopically with fluoroscopic control in the X-ray department but withoutthe support of an interventional radiologist.Data was collected prospectively on a pre-designed database.RESULTS:The indication for all stent procedures was an obstructing colorectal malignancy.Out of 53patients,the overall success rate was 90.6%.Eight patients had a stent intended as a bridge to surgery and 45 as a palliative procedure.Technical success was achieved in 50 out of 53 procedures(94.3%)and clinical success in 48 of those remaining 50(96.0%).Those with unsuccessful technical or clinical procedures went on to have defunctioning stomas to treat their obstruction.There were six complications from the technically successful stents(12.0%).These included one migration,one persisting obstructive symptoms and four cases of tumour overgrowth of the stents at a later date.Haemorrhagic complications,perforation or mortality were not observed in our series.Our results are comparable to several other studies assessing stent outcomes for obstructing bowel cancer.CONCLUSION:Our data suggests that colorectal stents can be inserted without radiologist support by an adequately trained individual with good outcomes. | Rao Khalid Mehmood Jody Parker Patricia Kirkbride Shakil Ahmed Fayyaz Akbar Eays Qasem Muhammad Zeeshan Ernest Jehangir | 2014 | World Journal of Gastroenterology2014，20，20： | 1 |
| 14 | Unfolding the structural features of NASICON materials for sodium-ion full cells显示文摘Sodium-ion batteries(SIBs)are potential candidates for the replacement of lithium-ion batteries to meet the increasing demands of electrical storage systems due to the low cost and high abundance of sodium.Sodium superionic conductor(NASICON)structured materials have attracted enormous interest in recent years as electrode materials for safer and long-term performance of SIBs for electric energy storage smart grids.These materials have a threedimensional robust framework,high redox potential,thermal stability,and a fast Na^(+)-ion diffusion mechanism.However,NASICON has low intrinsic electronic conductivity,which limits the electrochemical performance.This review describes the structural features of NASICONs to illustrate the ion storage mechanism and electrochemical performance of SIBs.Details of the NASICON crystal structure,the affiliated Na^(+)-ion diffusion mechanism,morphology,and electrochemical performance of these materials in sodiumion half-cells as well as full cells are described.In addition to the application as electrode materials,the use of NASICONs as solid electrolytes is also elaborated in solid-state SIBs.Based on these aspects,we have provided more perspectives in terms of the commercialization of SIBs and strategies to overcome the limitations of NASICONs.Hence,this review is expected to provide the researchers of energy storage with an in-depth understanding of NASICON materials with the knowledge of structural features,which will provide a new avenue on the practicality of SIBs. | Muhammad Tayyab Ahsan Zeeshan Ali Muhammad Usman Yanglong Hou | 2022 | Carbon Energy2022，4，5： | 1 |
| 15 | Burning Regression Analysis for 3D Grain Configurations显示文摘Grain design is essentially filling a prescribed volume (chamber case) with a certain shape of propellant so as to ensure mission requirements. An infinite number of possibilities exist, covering from two dimensional to three dimensional grain designs. Accurate calculation of grain geometrical properties plays a vital role in performance prediction. In this paper a methodology has been presented for designing 3D grain configuration for Solid Rocket Motors (SRMs). The design process involves parametric modeling of the geometry in CAD software through dynamic variables that define the complex configuration. Initial geometry is defined in the form of a surface which defines the grain configuration. Grain burn back is achieved by making new surfaces at each web increment and calculating geometrical properties at each step. Geometrical calculations are based on volume and change in volume calculations. Models for Axisymetric and Finocyl grain configuration have been developed. Equilibrium pressure method is used to calculate the internal ballistics. The procedure adopted can be applied to any complex geometry in a relatively simple way for preliminary designing of grain configuration. | ALI Kamran LIANG Guozhu MUHAMMAD Zeeshan Siddiqui | 2010 | Computer Aided Drafting,Design and Manufacturing2010，20，1： | 1 |

| 17 | Seasonal variations in dissolved organic matter concentration and composition in an outdoor system for bank filtration simulation显示文摘Dissolved organic matter(DOM)in surface waters can vary markedly in character depending on seasonal variations such as rainfall intensity,UV radiations and temperature.Changes in DOM as well as temperature and rainfall intensity over the year can affect the biochemical processes occurring in bank filtration(BF).Identification and characterization of DOM in the surface water could help to optimize the water treatment and provide stable and safe drinking water.This study investigated year-long variations of DOM concentrations and compositions in a surface water of a circulated outdoor pond(research facility)connected to a BF passage.DOM was dominated by humic substances and a changing pattern of DOM in surface water was observed throughout the year.A significant increase of DOM(~38%)in surface water was noted in August compared to November.The fluorescent DOM showed that DOM in summer was enriched with the degradable fraction whilst non-degradable fraction was dominated in winter.A constant(1.7±0.1 mg/L)effluent DOM was recirculated in the system throughout the year.DOM removal through BF varied between 4%to 39%and was achieved within a few meters after infiltration and significantly correlated with influent DOM concentration(R^(2)=0.82,p<0.05).However,no significant(p>0.05)change in the removal of DOM was observed in two subsurface layers(upper and lower).This study highlights the presence of a constant non-degradable DOM in the bank filtrate,which was not affected by temperature,redox conditions and UV radiations. | Muhammad Zeeshan Omamah Ali Shamas Tabraiz Aki Sebastian Ruhl | 2024 | Journal of Environmental Sciences2024，，1： | 1 |
| 18 | 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 |
