| 1 | Selective hydrogenation of N-heterocyclic compounds over rhodium-copper bimetallic nanocrystals under ambient conditions显示文摘Bimetallic nanocrystals (BMNCs) with distinguished electronic and chemical properties from those of their parent metals,offer the opportunity to obtain new catalysts with enhanced selectivity,activity,and stability.Here we describe the facile synthesis of rhodium-copper bimetallic system with different compositions and uniform morphology for chemo selective hydrogenation of functionalized quinolines.Our findings demonstrate that Rh-Cu BMNCs exhibited composition dependent activity and selectivity.BMNCs with rhodium to copper ratio 3:1 surpassed individual Rh and Cu and other compositions both in activity and selectivity for quinolines hydrogenation and performed even better than Rh/C with same amount of Rh.Rh3Cui catalyst displayed excellent tolerance for synthetically significant functional groups such as -OH,NH2,F,particularly for aldehyde group which is very reactive towards reduction.These results suggested that the coexistence of rhodium and copper metals play important role in the enhancement of catalytic activity due to synergistic effects and revealed that bimetallic nanocrystals can be promising as practical catalysts for selective hydrogenation of quinoline and other substrates. | Muhammad Mateen Khadim Shah Zheng Chen Chen Chen Yadong Li | 2019 | Nano Research2019，12，7： | 6 |
| 2 | 子宫颈抹片检查常规筛查宫颈组织、癌前病变或癌变在发展中国家门诊中的运用(英文)显示文摘Objective: Papanicolou (Pap) smear screening has dramatically reduced the incidence of invasive cervical cancer worldwide. Pap smear screening is still not widely available in developing countries and therefore cannot be used as mass screening tool. This study was designed to establish the role of Pap smear as a routine investigation for females presented to gynecological department. Methods: It was a hospital based study. Patients attending with complaints including irregular vaginal bleeding, vagina discharge, dyspareunia, low backache or lower abdominal pain and primary or secondary infertility were included in the study. All these patients underwent pap smear. Results: Age of females was 25 to 60 years. Ninety females had dysplasia. Mild to moderate dysplasia was positive in 84 females. Six patients had severe dysplasia suspicious for squamous cell carcinoma (SCC) which was confirmed as invasive SCC on biopsy. All patients with mild to moderate dysplasia were regularly followed at 4 to 6 months. Thirty patients were lost during follow up. Forty had negative smear at 6 months, while fourteen having persistent dysplasia on repeated pap smears were referred for biopsies. Histopathology confirmed invasive SCC in five patients while chronic cervicitis was reported in nine patients. Only two of screened patients with high suspicion for cancer showed false negative results. Directed biopsies done in these confirmed invasive SCC. Conclusion: Pap smear is a useful, simple, non-invasive and reliable screening tool for cervical cancer. It may be practiced as a routine investigation in outpatients in developing countries, where mass screening is not available. | Rubina Mukhtar Maham Munir Allah Rakha Abdul Mateen Rab Nawaz Maken Muhammad Arif | 2011 | The Chinese-German Journal of Clinical Oncology2011，10，10： | 1 |
| 3 | 通过乙胺盐酸盐添加剂工程提升MAPbI3钙钛矿太阳电池的光电性能显示文摘钙钛矿光吸收层的质量对太阳电池的光伏性能有重要的影响.目前,制备甲基铵基碘化铅钙钛矿(MAPbI3)的方法会产生大量缺陷态,特别是在晶界和薄膜表面,这些问题阻碍了钙钛矿太阳电池性能进一步提升.本文介绍了一种采用乙胺盐酸盐(EACl)添加剂制备高质量MAPbI3的特殊方法,发现EACl可以使得钙钛矿晶体不通过中间相形成,并在退火后从钙钛矿中蒸发.此外,该方法还获得了梯度钙钛矿结构,显著提高了钙钛矿薄膜的性能.在最佳EACl用量下,器件的光电转换效率(PCE)达到20.03%.器件在室温老化1000 h后仍能保持原有PCE的89%.这一新方法可以简易制备高质量、缺陷少的钙钛矿薄膜,以生产更加稳定的器件. | Muhammad Mateen Zulqarnain Arain 刘雪朋 Atif Iqbal 任英科 张先付 刘成 陈钦 马爽 丁勇 蔡墨朗 戴松元 | 2020 | Science China Materials2020，63，12： | 1 |
| 4 | Engineering electrophilic atomic Ir sites on CeO_(2) colloidal spheres for selectivity control in hydrogenation of α,β-unsaturated carbonyl compounds显示文摘Selective hydrogenation of the carbonyl bond inα,β-unsaturated carbonyl compounds is rather challenging owing to the more feasible hydrogenation of ethylenic bond from both thermodynamic and kinetic aspects.Here,we demonstrate a facile emulsionbased molecule-nanoparticle self-assembly strategy for the atomic engineering of Ir species on three-dimensional CeO_(2)spheres(Ir1@CeO_(2)).When applied to the hydrogenation ofα,β-unsaturated aldehydes,Ir1@CeO_(2)catalyst remarkably exhibited~100%selectivity towards unsaturated alcohols,whereas the formation of Ir nanoparticles on CeO_(2)drastically decreased the selectivity for unsaturated alcohols.Spectroscopic studies revealed that strong metal-support interactions triggered the charge transfer from Ir to CeO_(2),leading to the partial reduction of Ce^(4+)to Ce^(3+)along with the formation new Ir^(δ+)-O_(2)--Ce^(3+)(OV)interfaces.The electrophilic atomic Ir species at the Ir^(δ+)-O_(2)--Ce^(3+)(OV)interfaces would therefore preferentially adsorb and facilitate hydrogenation of polar C=O bond to achieve exceptional selectivity. | Muhammad Mateen Muhammad Nadeem Akhtar Ling Gao Weng-Chon(Max)CHEONG Shanshan Lv Yan Zhou Zheng Chen | 2022 | Nano Research2022，15，8： | 1 |
| 5 | Versatile effectors of phytopathogenic fungi target host immunity显示文摘Phytopathogenic fungi secrete a large arsenal of effector molecules,including proteinaceous effectors,small RNAs,phytohormones and derivatives thereof.The pathogenicity of fungal pathogens is primarily determined by these effectors that are secreted into host cells to undermine innate immunity,as well as to facilitate the acquisition of nutrients for their in planta growth and proliferation.After conventional and non-conventional secretion,fungal effectors are translocated into different subcellular compartments of the host cells to interfere with various biological processes.In extracellular spaces,apoplastic effectors cope with physical and chemical barriers to break the first line of plant defenses.Intracellular effectors target essential immune components on the plasma membrane,in the cytosol,including cytosolic organelles,and in the nucleus to suppress host immunity and reprogram host physiology,favoring pathogen colonization.In this review,we comprehensively summarize the recent advances in fungal effector biology,with a focus on the versatile virulence functions of fungal effectors in promoting pathogen infection and colonization.A perspective of future research on fungal effector biology is also discussed. | Muhammad Tariqjaveed Abdul Mateen Shanzhi Wang Shanshan Qiu Xinhang Zheng Jie Zhang Vijai Bhadauria Wenxian Sun | 2021 | Journal of Integrative Plant Biology2021，63，11： | 1 |
| 6 | High glucose microenvironment and human mesenchymal stem cell behavior显示文摘High glucose(HG)culture conditions in vitro and persistent exposure to hyperglycemia in diabetes patients are detrimental to stem cells,analogous to any other cell type in our body.It interferes with diverse signaling pathways,i.e.mammalian target of rapamycin(mTOR)-phosphoinositide 3-kinase(PI3K)-Akt signaling,to impact physiological cellular functions,leading to low cell survival and higher cell apoptosis rates.While elucidating the underlying mechanism responsible for the apoptosis of adipose tissue-derived mesenchymal stem cells(MSCs),a recent study has shown that HG culture conditions dysregulate mTORPI3K-Akt signaling in addition to mitochondrial malfunctioning due to defective mitochondrial membrane potential(MtMP)that lowers ATP production.This organelle-level dysfunction energy-starves the cells and increases oxidative stress and ultrastructural abnormalities.Disruption of the mitochondrial electron transport chain produces an altered mitochondrial NAD+/NADH redox state as evidenced by a low NAD+/NADH ratio that primarily contributes to the reduced cell survival in HG.Some previous studies have also reported altered mitochondrial membrane polarity(causing hyperpolarization)and reduced mitochondrial cell mass,leading to perturbed mitochondrial homeostasis.The hostile microenvironment created by HG exposure creates structural and functional changes in the mitochondria,altering their bioenergetics and reducing their capacity to produce ATP.These are significant data,as MSCs are extensively studied for tissue regeneration and restoring their normal functioning in cell-based therapy.Therefore,MSCs from hyperglycemic donors should be cautiously used in clinical settings for cell-based therapy due to concerns of their poor sur-vival rates and increased rates of post engraftment proliferation.As hypergly-cemia alters the bioenergetics of donor MSCs,rectifying the loss of MtMP may be an excellent target for future research to restore the normal functioning of MSCs in hyperglycemic patients. | Muhammad Abdul Mateen Nouralsalhin Alaagib Khawaja Husnain Haider | 2024 | World Journal of Stem Cells2024，16，3： | 0 |
| 7 | Automated Brain Hemorrhage Classification and Volume Analysis显示文摘Brain hemorrhage is a serious and life-threatening condition. It cancause permanent and lifelong disability even when it is not fatal. The wordhemorrhage denotes leakage of blood within the brain and this leakage ofblood from capillaries causes stroke and adequate supply of oxygen to thebrain is hindered. Modern imaging methods such as computed tomography(CT) and magnetic resonance imaging (MRI) are employed to get an idearegarding the extent of the damage. An early diagnosis and treatment can savelives and limit the adverse effects of a brain hemorrhage. In this case, a deepneural network (DNN) is an effective choice for the early identification andclassification of brain hemorrhage for the timely recovery and treatment of anaffected person. In this paper, the proposed research work is divided into twonovel approaches, where, one for the classification and the other for volumecalculation of brain hemorrhage. Two different datasets are used for twodifferent techniques classification and volume. A novel algorithm is proposedto calculate the volume of hemorrhage using CT scan images. In the firstapproach, the ‘RSNA’ dataset is used to classify the brain hemorrhage typesusing transfer learning and achieved an accuracy of 93.77%. Furthermore,in the second approach, a novel algorithm has been proposed to calculate thevolume of brain hemorrhage and achieved tremendous results as 1035.91mm3and 9.25 cm3, using the PhysioNet CT scan tomography dataset. | Maryam Wardah Muhammad Mateen Tauqeer Safdar Malik Mohammad Eid Alzahrani Adil Fahad Abdulmohsen Almalawi Rizwan Ali Naqvi | 2023 | Computers, Materials & Continua2023，，4： | 0 |
| 8 | Mask guided diverse face image synthesis显示文摘Recent studies have shown remarkable success in face image generation task.However,existing approaches have limited diversity,quality and controllability in generating results.To address these issues,we propose a novel end-to-end learning framework to generate diverse,realistic and controllable face images guided by face masks.The face mask provides a good geometric constraint for a face by specifying the size and location of different components of the face,such as eyes,nose and mouse.The framework consists of four components:style encoder,style decoder,generator and discriminator.The style encoder generates a style code which represents the style of the result face;the generator translate the input face mask into a real face based on the style code;the style decoder learns to reconstruct the style code from the generated face image;and the discriminator classifies an input face image as real or fake.With the style code,the proposed model can generate different face images matching the input face mask,and by manipulating the face mask,we can finely control the generated face image.We empirically demonstrate the effectiveness of our approach on mask guided face image synthesis task. | Song SUN Bo ZHAO Muhammad MATEEN Xin CHEN Junhao WEN | 2022 | Frontiers of Computer Science2022，16，3： | 0 |
| 9 | Pyridine-triphenylamine hole transport material for inverted perovskite solar cells显示文摘In the light of superior interaction between pyridine unit and perovskite,a facile star-shaped triphenylamine-based hole transport material(HTM)incorporating pyridine core(coded as H-Pyr)is designed and synthesized.A reference HTM with benzene core,coded as H-Ben,is also prepared for a comparative study.The effects of varying core on HTMs are investigated by comparing the photophysical,electrochemical and hole mobility properties.It is found that pyridine core exhibits better conjunction and decreased dihedral angles with triphenylamine side arms than that of benzene,leading to obviously better hole mobility and well-matched work function.The perovskite film prepared on H-Pyr also shows improved crystallization than on H-Ben.Photoluminescence and electrochemical impedance studies indicate improved charge extraction and reduced recombination in the H-Pyr-based perovskite solar cells.Consequently,H-Pyr-based device exhibits higher efficiency than H-Ben-based one.After doping with a Lewis acid,tris(pentafluorophenyl)borane,H-Pyr-based device delivers a champion efficiency of 17.09%,which is much higher compared with 12.14% of the device employing conventional poly(3,4-ethy lenedioxythiophene)polystyrene sulfonate(PEDOT:PSS)as HTM.Moreover,the H-Pyr-based device displays good long-term stability that the power conversion efficiency remains over 80% of the initial value after storage in ambient(relative humidity=50±5%)for 20 days. | Shuang Ma Xianfu Zhang Xuepeng Liu Rahim Ghadari Molang Cai Yong Ding Muhammad Mateen Songyuan Dai | 2021 | Journal of Energy Chemistry2021，30，3： | 0 |
| 10 | Tuning-up Learning Parameters for Deep Convolutional Neural Network:A Case Study for Hand-Drawn Sketch Images显示文摘Several recent successes in deep learning(DL),such as state-of-the-art performance on several image classification benchmarks,have been achieved through the improved configuration.Hyperparameters(HPs)tuning is a key factor affecting the performance of machine learning(ML)algorithms.Various state-of-the-art DL models use different HPs in different ways for classification tasks on different datasets.This manuscript provides a brief overview of learning parameters and configuration techniques to show the benefits of using a large-scale handdrawn sketch dataset for classification problems.We analyzed the impact of different learning parameters and toplayer configurations with batch normalization(BN)and dropouts on the performance of the pre-trained visual geometry group 19(VGG-19).The analyzed learning parameters include different learning rates and momentum values of two different optimizers,such as stochastic gradient descent(SGD)and Adam.Our analysis demonstrates that using the SGD optimizer and learning parameters,such as small learning rates with high values of momentum,along with both BN and dropouts in top layers,has a good impact on the sketch image classification accuracy. | Shaukat Hayat Kun She Muhammad Mateen Parinya Suwansrikham Muhammad Abdullah Ahmed Alghaili | 2022 | Journal of Electronic Science and Technology2022，20，3： | 0 |
| 11 | Effort-aware cross-project just-in-time defect prediction framework for mobile apps显示文摘As the boom of mobile devices,Android mobile apps play an irreplaceable roles in people’s daily life,which have the characteristics of frequent updates involving in many code commits to meet new requirements.Just-in-Time(JIT)defect prediction aims to identify whether the commit instances will bring defects into the new release of apps and provides immediate feedback to developers,which is more suitable to mobile apps.As the within-app defect prediction needs sufficient historical data to label the commit instances,which is inadequate in practice,one alternative method is to use the cross-project model.In this work,we propose a novel method,called KAL,for cross-project JIT defect prediction task in the context of Android mobile apps.More specifically,KAL first transforms the commit instances into a high-dimensional feature space using kernel-based principal component analysis technique to obtain the representative features.Then,the adversarial learning technique is used to extract the common feature embedding for the model building.We conduct experiments on 14 Android mobile apps and employ four effort-aware indicators for performance evaluation.The results on 182 cross-project pairs demonstrate that our proposed KAL method obtains better performance than 20 comparative methods. | Tian CHENG Kunsong ZHAO Song SUN Muhammad MATEEN Junhao WEN | 2022 | Frontiers of Computer Science2022，16，6： | 0 |
| 12 | Adaptive Multi-Cost Routing Protocol to Enhance Lifetime for Wireless Body Area Network显示文摘Wireless Body Area Network(WBAN)technologies are emerging with extensive applications in several domains.Health is a fascinating domain of WBAN for smart monitoring of a patient’s condition.An important factor to consider in WBAN is a node’s lifetime.Improving the lifetime of nodes is critical to address many issues,such as utility and reliability.Existing routing protocols have addressed the energy conservation problem but considered only a few parameters,thus affecting their performance.Moreover,most of the existing schemes did not consider traffic prioritization which is critical in WBANs.In this paper,an adaptive multi-cost routing protocol is proposed with a multi-objective cost function considering minimum distance from sink,temperature of sensor nodes,priority of sensed data,and maximum residual energy on sensor nodes.The performance of the proposed protocol is compared with the existing schemes for the parameters:network lifetime,stability period,throughput,energy consumption,and path loss.It is evident from the obtained results that the proposed protocol improves network lifetime and stability period by 30%and 15%,respectively,as well as outperforms the existing protocols in terms of throughput,energy consumption,and path loss. | Muhammad Mateen Yaqoob Waqar Khurshid Leo Liu Syed Zulqarnain Arif Imran Ali Khan Osman Khalid Raheel Nawaz | 2022 | Computers, Materials & Continua2022，，7： | 0 |
| 13 | Aloe vera Coating Efficiency on Shelf Life of Eggplants at Differential Storage Temperatures显示文摘The core objective of instant study was to check the effectiveness of Aloe vera edible coating on postharvest life and physicochemical characteristics of eggplants under different storage temperatures. For this purpose, different formulations of Aloe vera based coating(non-poisonous) was applied at concentration of 0, 0.1%, 0.5%, and 1.0%, respectively on eggplants.The coated eggplants were stored at two different temperatures [10℃ and(30±2)℃] and examined for weight loss, fi rmness, stem color, shriveling, total soluble solids, p H, acidity, vitamin C, sugar(total sugar, reducing sugar and non-reducing sugar) and N, P, K, Ca and Na for two weeks. The obtained results showed that weight loss, shriveling, total soluble solids, p H, sugar(total sugar and non-reducing sugar) increased and fi rmness, stem color, acidity, reducing sugar, vitamin C minimized during the storage period. The 0.5% Aloe coating at 10℃ showed signifi cant effect and delayed the changes in above parameters. Aloe vera coating remained almost ineffective in altering nutrient homeostasis(N, P, K, Ca and Na) of eggplants. The optimistic results gained in the current study could additionally investigate in larger market experiments and also could extensive to other tropical/subtropical fruits and vegetables. | Sikandar Amanullah Mtthammad Muzammil Jahangir Rao Muhammad Ikram Mateen Sajid Farhat Abbas Ali Inayat Mallano | 2016 | Journal of Northeast Agricultural University(English Edition)2016，23，4： | 0 |
