| 1 | Magnetically treated water irrigation effect on turnip seed germination,seedling growth and enzymatic activities显示文摘Pre-sowing magnetic field seed treatment effects on biological characteristics of vegetables and crops have been studied well.However,studies reporting irrigation with magnetically treated water are scanty.Therefore,the effect of irrigation with magnetically treated water on turnip seed germination,seedling growth and enzymatic activities was evaluated.The tap water was treated at 211 mT for 30,45 and 60 min and used for irrigation of turnip seed and seedlings.Uniform and healthy turnip seed was sown under randomized complete block design(RCBD).The germination,emergence rate index,vigor index I and vigor index II increased up to 28.33%,11.54%,57.59%and 32.26%,respectively.The growth parameters such as seedling lengths,fresh&dry weights,chlorophyll content were also enhanced in response of irrigation with magnetically treated water.The seedlings irrigated with magnetically treated water showed 28.92%,11.36%and 14.76%higher protein content,alpha amylase and protease activities,respectively vs control.Results revealed that irrigation with magnetically treated water has potential to improve turnip germination,seedling growth and enzymatic activities and this study is also extendable to other vegetables and crops for the improvement of germination and growth. | Zia ul Haq Munawar Iqbal Yasir Jamil Hafeez Anwar Ayesha Younis Muhammad Arif M.Zeshan Fareed Fida Hussain | 2016 | Information Processing in Agriculture2016，3，2： | 5 |
| 2 | Silver modified Cu/SiO2 catalyst for the hydrogenation of methyl acetate to ethanol显示文摘A series of silver modified Cu/SiO2 catalysts were synthesized with ammonia-evaporation method and applied in vapor-phase hydrogenation of methyl acetate to ethanol.The influence of additive‘Ag’on the structural evolution of catalyst was systematically studied by several characterization techniques,such as N2 adsorption–desorption,N2O titration,PXRD,FTIR,in-situ FTIR,H2-TPR,H2-TPD,XPS and TEM.Results showed that incorporation of a small amount of Ag could enhance the structural stability,and the strong interaction between Cu and Ag species was conducive to increase the dispersion of copper species and create a suitable Cu+/(Cu0+Cu+)ratio,which was proposed to be responsible for the improved catalytic activity.The maximum conversion of MA(94.1%)and selectivity of ethanol(91.3%)over optimized Cu-0.5 Ag/SiO2 and 120 h on stream without deactivation under optimal conditions demonstrates its excellent stability. | Zhiheng Ren Muhammad Naeem Younis Hui Zhao Chunshan Li Xiangui Yang Erqiang Wang Gongying Wang | 2020 | Chinese Journal of Chemical Engineering2020，28，6： | 4 |

| 4 | Water-induced softening behavior of clay-rich sandstone in Lanzhou Water Supply Project,China显示文摘The strength of clay-rich sandstone decreases significantly when in contact with water due to softening effects.This scenario can pose a severe threat to the stability of water diversion tunnels during construction and operation periods.To address the issues related to water-induced softening in clay-rich sandstone zones in a water diversion tunnel of Lanzhou Water Supply Project,the microscopic and micromechanical variations of rocks due to increasing water content in two different zones i.e.zones A and B,were determined by various testing methods,such as X-ray diffraction(XRD),scanning electron microscopy(SEM),thin section microscopy,micro-indentation test,sonic velocity test,and slake durability test.The microscopic analysis confirms the presence of montmorillonite mineral which is the dominant problematic geomaterial in engineering application.The integrity and durability of clay-rich sandstone were determined with sonic velocity and slake durability tests to calibrate the results obtained by the micro-indentation test.It shows that the elastic modulus and hardness of clay-rich sandstone decrease with the increase of saturation time,up to 144 h,which is more significant and rapid during early stage of saturation.After 144 h of saturation,the elastic modulus decreases by 89% and 97%,and the hardness decreases by 89% and 99% for zones A and B sandstones,respectively.The results of slake durability and sonic velocity indicate that zone A sandsto ne remains 56.19% durability after 144 h of saturation,while zone B sandstone loses its durability merely after 72 h of saturation.The clay-rich sandstone starts to dissolve in water when the saturation time exceeds 144 h.The significant decreases in strength and durability of clay-rich sandstone due to water-induced softening are serious threats to tunnel stability.The improvements in the strength of surrounding rock mass by grouting and permeability by installation of drainage galleries can reduce the damage caused by water-induced softening. | Muhammad Usman Azhar Hui Zhou Fanjie Yang Adnan Younis Xinjing Lu Houguo Fang Yijun Geng | 2020 | Journal of Rock Mechanics and Geotechnical Engineering2020，12，3： | 3 |
| 5 | Optical spin-symmetry breaking for high-efficiency directional helicity-multiplexed metaholograms显示文摘Helicity-multiplexed metasurfaces based on symmetric spin–orbit interactions (SOIs) have practical limits because they cannot provide central-symmetric holographic imaging. Asymmetric SOIs can effectively address such limitations, with several exciting applications in various fields ranging from asymmetric data inscription in communications to dual side displays in smart mobile devices. Low-loss dielectric materials provide an excellent platform for realizing such exotic phenomena efficiently. In this paper, we demonstrate an asymmetric SOI-dependent transmission-type metasurface in the visible domain using hydrogenated amorphous silicon (a-Si:H) nanoresonators. The proposed design approach is equipped with an additional degree of freedom in designing bi-directional helicity-multiplexed metasurfaces by breaking the conventional limit imposed by the symmetric SOI in half employment of metasurfaces for one circular handedness. Two on-axis, distinct wavefronts are produced with high transmission efficiencies, demonstrating the concept of asymmetric wavefront generation in two antiparallel directions. Additionally, the CMOS compatibility of a-Si:H makes it a cost-effective alternative to gallium nitride (GaN) and titanium dioxide (TiO2) for visible light. The cost-effective fabrication and simplicity of the proposed design technique provide an excellent candidate for high-efficiency, multifunctional, and chip-integrated demonstration of various phenomena. | Muhammad Ashar Naveed Muhammad Afnan Ansari Inki Kim Trevon Badloe Joohoon Kim Dong Kyo Oh Kashif Riaz Tauseef Tauqeer Usman Younis Murtaza Saleem Muhammad Sabieh Anwar Muhammad Zubair Muhammad Qasim Mehmood Junsuk Rho | 2021 | Microsystems & Nanoengineering2021，7，2： | 3 |
| 6 | Topological evolution of laminar juncture flows under different critical parameters显示文摘Horseshoe vortex topological structure has been studied extensively in the past,traditional'saddle of separation'and new'attachment saddle point'topologies found in literature both have theoretical basis and experimental and computational evidences for support.The laminar incompressible juncture flows at low Reynolds numbers especially are observed to have new topology.Studies concerning the existence of the new topology though found in literature,the topological evolution and its dependency on various critical flow parameters require further investigation.A Particle Image Velocimetry based analysis is carried out to observe the effect of aspect ratio,?*/D and shape of the obstacle on laminar horseshoe vortex topology for small obstacles.Rise in aspect ratio evolves the topology from the traditional to new for all the cases observed.The circular cross section obstacles are found more apt to having the new topology compared to square cross sections.It is noted that the sweeping effect of the fluid above the vortex system in which horseshoe vortex is immersed plays a critical role in this evolution.Topological evolution is observed not only in the most upstream singular point region of horseshoe vortex system but also in the corner region.The corner vortex topology evolves from the traditional type to new one before the topological evolution of the most upstream singular point,resulting in a new topological pattern of the laminar juncture flows'separation-attachment combination'.The study may help extend the understanding of the three-dimensional boundary layer separation phenomenon. | YOUNIS Muhammad Yamin ZHANG Hua HU Bo MEHMOOD Saqib | 2014 | Science China(Technological Sciences)2014，57，7： | 1 |
| 7 | Appraisal of Improvement in Physiological and Metabolic Processes by Exogenously Applied Natural and Synthetic Ascorbic Acid in Okra(Abelmoschus esculentus L.)Fruit Subjected to Water Deficit Stress显示文摘To counteract the effects of drought stress,scientists have adopted several approaches including the use of different chemicals both inorganic and organic,which is contemplated as a highly efficient and cost-effective shot-gun approach.Ascorbic acid(AsA)is a potential organic substance,which widely occurs in plants,and is considered to be an effective antioxidant to counteract reactive oxygen species(ROS).Thus,a pot experiment was performed to assess the relative mitigating impacts of synthetic AsA and naturally occurring AsA in the form of lemon juice(LJ)and orange juice(OJ)on two cultivars of okra(Abelmoschus esculentus L.)namely Sabz Pari and Bhindi Sanwali under varying water deficit conditions.After 30 days of seed germination,okra seedlings were subjected to different irrigation regimes,i.e.,water deficit stress[(65%and 50%F.C.)and control conditions(100%F.C.)].Different levels of AsA[control(no spray),14 mg L^(−1)LJ,24 mg L^(−1)OJ and 150 mg L^(−1)AsA]obtained from different sources were applied as a foliar spray to control and water-stressed plants.Drought stress prominently reduced plant growth and yield attributes of the okra cultivars.Water-deficit conditions(65%and 50%F.C.)substantially decreased the fruit chlorophyll(a,b)pigments and the activity of superoxide dismutase(SOD)enzyme,while an increase was observed in the contents of fruit’s hydrogen peroxide(H_(2)O_(2)),malondialdehyde(MDA),total phenolics,total soluble sugars,AsA,and total soluble proteins.Drought stress also increased the activities of antioxidant enzymes like peroxidase(POD)and catalase(CAT).However,plant growth and yield attributes,fruit chlorophyll pigments,total phenolics,total soluble sugars,total free amino acids,total soluble proteins,AsA,GB,H_(2)O_(2),and the activities of antioxidant enzymes(POD and CAT)were increased by the AsA exogenous treatment in both okra cultivars under water deficit and control conditions.Overall,LJ and OJ were more effective than the synthetic AsA in upregulating the physiological and metabolic processes of okra plants.So,cost-effective as well as multi-nutrient natural sources of AsA could be suggested for alleviating the harmful effects of water deficit stress on plants. | Muhammad Younis Nudrat Aisha Akram Arafat Abdel Hamed Abdel Latef Muhammad Ashraf | 2023 | Phyton-International Journal of Experimental Botany2023，92，10： | 0 |
| 8 | Interaction properties of solitons for a couple of nonlinear evolution equations显示文摘We study one-and two-soliton solutions for the Cahn–Allen(CA) equation and the Brethorton equation. The CA equation has broad spectrum of applications especially in anti-phase boundary motion and it is used in phase-field models.While the Brethorton equation is a model for dispersive wave systems, it is used to find the resonant nonlinear interaction among three linear modes. We use the Hirota bilinear method to obtain one-and two-soliton solutions to the CA equation and the Brethorton equation. | Syed Tahir Raza Rizvi Ishrat Bibi Muhammad Younis Ahmet Bekir | 2021 | Chinese Physics B2021，30，1： | 0 |

| 11 | Circulating miR-548c-3p possesses good diagnostic potential for metabolic syndrome显示文摘Studies have shown that dysregulated expression of miRNAs is a major underlying event in the onset and progression of many metabolic diseases.The pathological role of miR-548c-3p in various cancer types,including breast cancer,glioma,prostate cancer,and gastric cancer,has been documented.1 However,experimental evidences validating the role of miR-548c-3p in the development of metabolic diseases are still lacking,and no data is available on its diagnostic potential for metabolic syndrome(MS).Recently,we predicted the involvement of miR-548c-3p in the pathogenesis of MS and its progression to cardiovascular diseases(CVD)via the regulation of target genes necessary for the proper function of insulin resistance,mTOR,and JAK/STAT signaling pathways.2 Therefore,we deemed it necessary to engage in wet laboratory analysis and validate these claims in patients with metabolic syndrome compared to healthy individuals. | Abdullahi Dandare Afrose Liaquat Muhammad Rafiq Mbah Ntepe Leonel Javeres Sidra Younis Muhammad Jawad Khan | 2023 | Genes & Diseases2023，10，3： | 0 |
| 12 | Evolution of Coulomb failure stress in Sulaiman Lobe,Pakistan,and its implications for seismic hazard assessment显示文摘In this research work,we present the evolution of Coulomb failure stress(CFS)in the Sulaiman Lobe and its implications for seismic hazard assessment.The Chaman transform fault,~1,000 km long,is the major active fault that marks the western boundary between Pakistan and Afghanistan on the Indian Plate.To date,few studies have been conducted to unveil the interactions among earthquakes and the implications of these interactions for seismic hazard assessment in the region.We thoroughly investigated the published and online catalog to construct a sequence of major earthquakes that occurred in this region during the past.The final earthquake sequence was composed of 15 earthquakes of M_(w)≥6.0,beginning with the 1888 earthquake.We used the stress-triggering theory to numerically simulate the evolution of CFS caused by these earthquakes.The numerical results revealed that 8 out of 15earthquakes were triggered by the preceding earthquakes.The earthquakes in 1908,1910,1935,1966,and 1997 were rather independent earthquakes in this sequence.Although the epicenters of the 1975a and 1975b earthquakes were in the stress shadow zone,the partial rupture segments of both these earthquakes were in high-CFS regions.The CFS induced by the 1935 earthquake was notable,as it later triggered the 2008 doublet.Moreover,our results revealed that the northern segment of the Chaman Fault,the southern segment of the Ghazaband Fault,and the northwestern segment of the Urghargai Fault demonstrated a high change in CFS that could trigger seismicity in these regions.The necessary arrangements must therefore be made to mitigate any possible seismic hazards in the region. | Aiza Amjad Muhammad Shahid Riaz Urooj Shakir Muhammad Younis Khan Muhammad Ali Shah | 2023 | Earth and Planetary Physics2023，7，2： | 0 |
| 13 | On global behavior for complex soliton solutions of the perturbed nonlinear Schrödinger equation in nonlinear optical fibers显示文摘In this research article,the perturbed nonlinear Schrödinger equation(P-NLSE)is examined by utilizing two analytical methods,namely the extended modified auxiliary equation mapping and the generalized Riccati equation mapping methods.Consequently,we establish several sorts of new families of complex soliton wave solutions such as hyperbolic functions,trigonometric functions,dark and bright solitons,periodic solitons,singular solitons,and kink-type solitons wave solutions of the P-NLSE.Using the mentioned methods,the results are displayed in 3D and 2D contours for specific values of the open parameters.The obtained findings demonstrate that the implemented techniques are capable of identifying the exact solutions of the other complex nonlinear evolution equations(C-NLEEs)that arise in a range of applied disciplines. | M.S.Osman Hassan Almusawa Kalim U.Tariq Sadia Anwar Sachin Kumar Muhammad Younis Wen-Xiu Ma | 2022 | Journal of Ocean Engineering and Science2022，7，5： | 0 |
| 14 | Modulation instability analysis, optical and other solutions to the modified nonlinear Schr?dinger equation显示文摘This paper studies the new families of exact traveling wave solutions with the modified nonlinear Schrodinger equation,which models the propagation of rogue waves in ocean engineering.The extended Fan sub-equation method with five parameters is used to find exact traveling wave solutions.It has been observed that the equation exhibits a collection of traveling wave solutions for limiting values of parameters.This method is beneficial for solving nonlinear partial differential equations,because it is not only useful for finding the new exact traveling wave solutions,but also gives us the solutions obtained previously by the usage of other techniques(Riccati equation,or first-kind elliptic equation,or the generalized Riccati equation as mapping equation,or auxiliary ordinary differential equation method)in a combined approach.Moreover,by means of the concept of linear stability,we prove that the governing model is stable.3 D figures are plotted for showing the physical behavior of the obtained solutions for the different values of unknown parameters with constraint conditions. | Muhammad Younis Tukur Abdulkadir Sulaiman Muhammad Bilal Shafqat Ur Rehman Usman Younas | 2020 | Communications in Theoretical Physics2020，72，6： | 0 |

| 16 | Rational design on photoelectrodes and devices to boost photoelectrochemical performance of solar-driven water splitting: a mini review显示文摘As an eco-friendly,efficient,and low-cost technique,photoelectrochemical water splitting has attracted growing interest in the production of clean and sustainable hydrogen by the conversion of abundant solar energy.In the photoelectrochemical system,the photoelectrode plays a vital role in absorbing the energy of sunlight to trigger the water splitting process and the overall efficiency depends largely on the integration and design of photoelectrochemical devices.In recent years,the optimization of photoelectrodes and photoelectrochemical devices to achieve highly efficient hydrogen production has been extensively investigated.In this paper,a concise review of recent advances in the modification of nanostructured photoelectrodes and the design of photoelectrochemical devices is presented.Meanwhile,the general principles of structural and morphological factors in altering the photoelectrochemical performance of photoelectrodes are discussed.Furthermore,the performance indicators and first principles to describe the behaviors of charge carriers are analyzed,which will be of profound guiding significance to increasing the overall efficiency of the photoelectrochemical water splitting system.Finally,current challenges and prospects for an in-depth understanding of reaction mechanisms using advanced characterization technologies and potential strategies for developing novel photoelectrodes and advanced photoelectrochemical water splitting devices are demonstrated. | Siliu Lyu Muhammad Adnan Younis Zhibin Liu Libin Zeng Xianyun Peng Bin Yang Zhongjian Li Lecheng Lei Yang Hou | 2022 | Frontiers of Chemical Science and Engineering2022，16，6： | 0 |
| 17 | A decline in snow cover area of Passu and Ghulkin valleys between 1995 and 2022显示文摘The global cryosphere is experiencing accelerated melting due to climate change.Currently,the Karakoram anomaly is under discussion with a debate about the possibility that the anomaly may have recently ended.This study aims to evaluate the up-to-date changes in snow cover in the western Karakoram region.We observed the snow cover changes in Passu and Ghulkin valleys in the Hunza River basin(HRB)of the Karakoram through multitemporal Landsat satellite data between 1995 and 2022.We found a significant reduction in snow cover in these valleys,with an average reduction rate of 0.42 km~2/yr,resulting in a total reduction of~11.46 km~2 between 1995 and 2022.This reduction in snow cover is consistent with the mass loss of glaciers in the Karakoram region in recent years.The decline in snow cover in these valleys is also consistent with the meteorological data.The temperature in summer(June)has significantly increased whereas the precipitation in the accumulation season(March)has decreased.These rapid changes suggest that it is crucially important to monitor the snow cover on a regular basis to support downstream management of snowmelt runoff.In addition,there is a need of planning for mitigation and adaptation strategies for snow-related hazards. | Imran HUSSAIN Mumtaz ALI Sher MUHAMMAD Wajid HASSAN Salar ALI Zakir HUSSAIN Syed Hammad ALI Shaukat ALI Muhammad Younis KHAN | 2023 | Journal of Mountain Science2023，20，12： | 0 |
| 18 | Mild hyperthermia-enhanced chemo-photothermal synergistic therapy using doxorubicin-loaded gold nanovesicles显示文摘Gold nanovesicles(GVs) with unique plasmonic property and large cavity hold great potential as a stimuli-responsive nanocarrier to deliver drugs for efficient tumor chemotherapy and other therapies synergistically.Herein,we developed doxorubicin-loaded gold nanovesicles(DGVs),offering infrared thermal(IRT) and photoacoustic(PA) dual-modal imaging guided mild hype rthermia-enhanced chemophotothermal cancer synergistic therapy.The DGVs are self-assembled by gold nanoparticles modified with amphiphilic copolymer in a predetermined concentration of doxorubicin through film rehydration method.Under the influence of laser excitation,the as-prepared DGVs exhibited good photothermal effect,which triggered the structural disruption of GVs and thus,allowed the efficient release of encapsulated DOX to enhance cell uptake for fluorescence imaging and tumor chemotherapy,respectively.In addition,DGVs also showed a strong PA and IRT signals in vivo.Our study demonstrated the potential of DGVs as stimuli-responsive drug delivery systems and cancer theranostics. | Zhuoting Deng Chao Jiang Muhammad Rizwan Younis Shan Lei Yaling He Haoxing Zheng Peng Huang Jing Lin | 2021 | Chinese Chemical Letters2021，32，8： | 0 |
