| 1 | 冷变形和热处理对TC21钛合金显微组织和力学性能的影响显示文摘研究冷变形、不同冷却速率的固溶处理以及时效处理对TC21钛合金(6.5Al-3Mo-1.9Nb-2.2Sn-2.2Zr-1.5Cr)显微组织、硬度和磨损性能的影响。对退火后试样进行15%(高度降低)的室温冷变形处理;然后,将样品在920℃下进行15min固溶处理,再分别进行不同冷却速率的水淬(WQ)、空冷(AC)和炉冷(FC)至室温;最后,将样品在590℃下时效4 h。结果发现,对于经固溶处理、空冷和时效处理后的样品,其残余β相中有二次α片状晶体析出。WQ和时效处理样品的硬度最高,为HV 470,这是由于存在大量残余β相(69%),而FC样品的硬度最低,为HV328。固溶处理后再时效处理可显著提高试样的耐磨性能,经水淬和时效处理后试样的耐磨性能可达到退火试样的122%。 | Ramadan N.ELSHAER Khaled M.IBRAHIM | 2020 | Transactions of Nonferrous Metals Society of China2020，30，5： | 8 |
| 2 | Multitarget therapeutic strategies for Alzheimer's disease显示文摘Neurodegenerative diseases such as Alzheimer's, Huntington's and Parkinson's diseases have multifaceted nature because of the different factors contributing to their progression. The complex nature of neurodegenerative diseases has developed a pressing need to design multitarget-directed ligands to address the complementary pathways involved in these diseases. The major enzyme targets for development of therapeutics for Alzheimer's disease are cholinesterase and β-secretase enzymes. In this review, we discuss recent advances in profiling single target inhibitors based on these enzymes to multitarget-directed ligands as potential therapeutics for this devastating disease. In addition, therapeutics based on iron chelation strategy are discussed as well. | Mostafa M.Ibrahim Moustafa T.Gabr | 2019 | Neural Regeneration Research2019，14，3： | 8 |
| 3 | Yield and tillering response of super hybrid rice Liangyoupeijiu to tillage and establishment methods显示文摘Tillering is an important agronomic trait for rice grain production. To evaluate yield and tillering response, Liangyoupeijiu(super hybrid rice) was grown in Hunan, China during 2011–2012 under different methods of tillage(conventional and no-tillage system) and crop establishment methods(transplanting at a spacing of 20 cm × 20 cm with one seedling per hill and direct seeding at a seeding rate of 22.5 kg ha-1). Our results revealed that, at maximum tillering(Max.) and at maturity(MA) stages, direct seeding(DS) resulted in 22% more tillers than transplanting(TP) irrespective of tillage system. Tiller mortality reached a peak between panicle initiation(PI) and booting(BT) stages, and was 16% higher under conventional tillage(CT) than under no-tillage(NT). Transplanting required 29% more time for the completion of tillering and less for DS. Tillering rate was 43% higher in DS than TP under either CT or NT. There was a positive correlation between panicle number per m2and maximum tiller number per m2, but not panicle-bearing tiller rate. The panicle bearing tiller rate was higher under DS than TP and higher under NT than CT. Tiller dry weight gradually increased up to heading(HD) stage, and was 14% higher under TP than DS. Leaf area(cm2tiller-1) gradually increased from Max. to HD stage and then decreased by 34% in conventional tillage transplanting(CTTP) and 45% in no-tillage transplanting(NTTP) from 12DAH–24DAH(days after heading), but was similar(35%) under DS under either CT or NT. Grain yield was higher under CTTP owing to the larger sink size(heavier panicle, more spikelets in per cm length of panicle) than under DS. | M.A.Badshah Naimei Tu Yingbin Zou M.Ibrahim Ke Wang | 2014 | The Crop Journal2014，2，1： | 5 |
| 4 | Perovskite Solar Cells Yielding Reproducible Photovoltage of 1.20 V显示文摘High photovoltages and power conversion efciencies of perovskite solar cells(PSCs)can be realized by controlling the undesired nonradiative charge carrier recombination.Here,we introduce a judicious amount of guanidinium iodide into mixed-cation and mixed-halide perovskite flms to suppress the parasitic charge carrier recombination,which enabled the fabrication of>20%efcient and operationally stable PSCs yielding reproducible photovoltageas high as 1.20 V.By introducing guanidinium iodide into the perovskite precursor solution,the bandgap of the resulting absorber material changed minimally;however,the nonradiative recombination diminished considerably as revealed by time-resolved photoluminescence and electroluminescence studies.Furthermore,using capacitance-frequency measurements,we were able to correlate the hysteresis features exhibited by the PSCs with interfacial charge accumulation.Tis study opens up a path to realize new record efciencies for PSCs based on guanidinium iodide doped perovskite flms. | Essa A.Alharbi M.Ibrahim Dar Neha Arora Mohammad Hayal Alotaibi Yahya A.Alzhrani Pankaj Yadav Wolfgang Tress Ahmed Alyamani Abdulrahman Albadri Shaik M.Zakeeruddin Michael Grätzel | 2019 | Research2019，，1： | 4 |

| 6 | Highly transmitted silver nanowires-SWCNTs conductive flexible film by nested density structure and aluminum-doped zinc oxide capping layer for flexible amorphous silicon solar cells显示文摘Indium tin oxide(ITO)is widely used in transparent conductive films(TCFs);however,several disadvan-tages,such as high cost and toxicity of indium,limit its applications.Therefore,it is necessary to develop other materials that can replace ITO.Silver nanowires or single walled carbon nanotubes(SWCNTs)have attracted considerable interest owing to their unique electrical,optical,and thermal stabilities,and thus,they are ideal for transparent electrodes for flexible or stretchable devices.In this study,we develop a novel architecture of composite TCFs on a polyethylene naphthalate(PEN)flexible substrate.Herein,the silver nanowires-SWCNTs films with nested density structure were fabricated through ultrasonic spraying technology by varying the spraying width.For achieving enhanced transmittance,we combined the larger irregular grids and holes with fewer nanowires stacked in the longitudinal direction,more optical chan-nels,and good carrier transport.Thereafter,aluminum-doped zinc oxide(AZO)was used as capping to the structure for enhancing the optical properties of the TCFs.The silver nanowires-SWCNTs/AZO(ASA)bilayer was obtained in the optimized architecture,which showed superior optoelectronic performance to that shown by commercial ITO with a high optical transmittance of 92%at the wavelength of 550 nm and low sheet resistance of 17/sq.In the specially structured conductive film,the significant improvement in the transmittance and uniformity of the sheet resistance was attributed to the effective nanowire junc-tion contact compared to that in ordinary structure of silver nanowires,which reduced the mean density of small clusters of nanowires.Compared with the silver nanowires-SWCNTs films,the ASA bilayer film exhibited excellent resistance to boiling,mechanical bending(10,000 cycles),and CO_(2)plasma.Moreover,the sheet resistance of ASA changed slightly after the tape tests,thereby illustrating a strong adhesion to the PEN substrate after the enclosure of AZO.Meanwhile,the AZO capping layer can enhance the op-tical transmittance between 600 and 1500 nm.In addition,the amorphous silicon photovoltaic devices with flexible ASA TCFs exhibited a power conversion efficiency(PCE)of 8.67%.After bending for 3000 times,the PCE was decreased to 8.20%,thereby demonstrating the potential of developed films to replace traditional ITO. | Shunliang Gao Xiaohui Zhao Qi Fu Tianchi Zhang Jun Zhu Fuhua Hou Jian Ni Chengjun Zhu Tiantian Li Yanlai Wang Vignesh Murugadoss Gaber A.M.Mersal Mohamed M.Ibrahim Zeinhom M.El-Bahy Mina Huang Zhanhu Guo | 2022 | Journal of Materials Science & Technology2022，，31： | 2 |
| 7 | Medical Image Compression Based on Wavelets with Particle Swarm Optimization显示文摘This paper presents a novel method utilizing wavelets with particle swarm optimization(PSO)for medical image compression.Our method utilizes PSO to overcome the wavelets discontinuity which occurs when compressing images using thresholding.It transfers images into subband details and approximations using a modified Haar wavelet(MHW),and then applies a threshold.PSO is applied for selecting a particle assigned to the threshold values for the subbands.Nine positions assigned to particles values are used to represent population.Every particle updates its position depending on the global best position(gbest)(for all details subband)and local best position(pbest)(for a subband).The fitness value is developed to terminate PSO when the difference between two local best(pbest)successors is smaller than a prescribe value.The experiments are applied on five different medical image types,i.e.,MRI,CT,and X-ray.Results show that the proposed algorithm can be more preferably to compress medical images than other existing wavelets techniques from peak signal to noise ratio(PSNR)and compression ratio(CR)points of views. | Monagi H.Alkinani E.A.Zanaty Sherif M.Ibrahim | 2021 | Computers, Materials & Continua2021，，5： | 1 |

| 12 | Detection of natural structures and classification of HCI-HPR data using robust forward search algorithm显示文摘Purpose-The purpose of this paper is to proposes a forward search algorithm for detecting and identifying natural structures arising in human-computer interaction(HCI)and human physiological response(HPR)data.Design/methodology/approach-The paper portrays aspects that are essential to modelling and precision in detection.The methods involves developed algorithm for detecting outliers in data to recognise natural patterns in incessant data such as HCI-HPR data.The detected categorical data are simultaneously labelled based on the data reliance on parametric rules to predictive models used in classification algorithms.Data were also simulated based on multivariate normal distribution method and used to compare and validate the original data.Findings-Results shows that the forward search method provides robust features that are capable of repelling over-fitting in physiological and eye movement data.Research limitations/implications-One of the limitations of the robust forward search algorithm is that when the number of digits for residuals value is more than the expected size for stack flow,it normally yields an error caution;to counter this,the data sets are normally standardized by taking the logarithmic function of the model before running the algorithm.Practical implications-The authors conducted some of the experiments at individual residence which may affect environmental constraints.Originality/value-The novel approach to this method is the detection of outliers for data sets based on the Mahalanobis distances on HCI and HPR.And can also involve a large size of data with p possible parameters.The improvement made to the algorithm is application of more graphical display and rendering of the residual plot. | Fatima Isiaka Kassim S.Mwitondi Adamu M.Ibrahim | 2016 | International Journal of Intelligent Computing and Cybernetics2016，9，1： | 0 |
| 13 | Assessing the Performance of Some Ranked Set Sampling Designs Using Hybrid Approach显示文摘In this paper,a joint analysis consisting of goodness-of-fit tests and Markov chain Monte Carlo simulations are used to assess the performance of some ranked set sampling designs.The Markov chain Monte Carlo simulations are conducted when Bayesian methods with Jeffery’s priors of the unknown parameters of Weibull distribution are used,while the goodness of fit analysis is conducted when the likelihood estimators are used and the corresponding empirical distributions are obtained.The ranked set sampling designs considered in this research are the usual ranked set sampling,extreme ranked set sampling,median ranked set sampling,and neoteric ranked set sampling designs.An intensive Monte Carlo simulation study is conducted using Lindley’s approximation algorithm to compute the different designs’-based estimators.The study showed that the dependent design“neoteric ranked set sampling design”is superior to other ranked set designs and the total relative efficiency is higher than the other designs’total relative efficiency. | Mohamed.A.H.Sabry Ehab M.Almetwally Hisham M.Almongy Gamal M.Ibrahim | 2021 | Computers, Materials & Continua2021，，9： | 0 |

| 17 | Improving Date Fruit Classification Using Cycle GAN-Generated Dataset显示文摘Dates are an important part of human nutrition.Dates are high in essential nutrients and provide a number of health benefits.Date fruits are also known to protect against a number of diseases,including cancer and heart disease.Date fruits have several sizes,colors,tastes,and values.There are a lot of challenges facing the date producers.One of the most significant challenges is the classification and sorting of dates.But there is no public dataset for date fruits,which is a major limitation in order to improve the performance of convolutional neural networks(CNN)models and avoid the overfitting problem.In this paper,an augmented date fruits dataset was developed using Deep Convolutional Generative Adversarial Networks(DCGAN)and CycleGAN approach to augment our collected date fruit datasets.This augmentation is required to address the issue of a restricted number of images in our datasets,as well as to establish a balanced dataset.There are three types of dates in our proposed dataset:Sukkari,Ajwa,and Suggai.After dataset augmentation,we train our created dataset using ResNet152V2 and CNN models to assess the classification process for our three categories in the dataset.To train these two models,we start with the original dataset.Thereafter,the models were trained using the DCGAN-generated dataset,followed by the CycleGAN-generated dataset.The resulting results demonstrated that when using the ResNet152V2model,the CycleGAN-generated dataset had the highest classification performance with 96.8%accuracy,followed by the CNN model with 94.3%accuracy. | Dina M.Ibrahim Nada M.Elshennawy | 2022 | Computer Modeling in Engineering & Sciences2022，，4： | 0 |
| 18 | An efficient nano-adsorbent via surfactants/dual surfactants assisted ultrasonic co-precipitation method for sono-removal of monoazo and diazo anionic dyes显示文摘To preserve the environment for civilization,we should remove the pollutants like toxic dyes by friendly and cost efficacious method.In this study,the effect of surfactants or mixed surfactants on physicochemical,optical and adsorption properties of ternary mixed oxide CeO_(2)-ZrO_(2)-Al_(2) O_3(CZA) are investigated.The ternary mixed oxide CZA was prepared by surfactants or mixed surfactants assisted ultrasonic coprecipitation method.The physicochemical and optical properties are estimated by different techniques like XRD,TEM,EDX,FTIR,S_(BET) and UV-Vis/DR.The CZA_T and CZA_C have hybrid shapes and high surface area.The adsorption properties of ternary mixed oxides adsorbents were characterized by sono-removing anionic dyes such as Congo red(CR) and Remazol red RB-133(RR).The different factors like contact time,different dye concentrations and temperatures also studied.The kinetics and isotherms applications showed that,the adsorption process was followed pseudo second order kinetics and the Freundlich isotherm model.Also,the adsorption is spontaneous and endothermic process through the thermodynamic study.Finally,the results showed that the ternary mixed oxide nano-adsorbent(CeO_(2)-ZrO_(2)-Al_(2) O_3) is promising and functional materials for anionic dye sweep from wastewater. | Marwa M.Ibrahim | 2021 | Chinese Journal of Chemical Engineering2021，34，12： | 0 |

| 20 | HLR-Net: A Hybrid Lip-Reading Model Based on Deep Convolutional Neural Networks显示文摘Lip reading is typically regarded as visually interpreting the speaker’s lip movements during the speaking.This is a task of decoding the text from the speaker’s mouth movement.This paper proposes a lip-reading model that helps deaf people and persons with hearing problems to understand a speaker by capturing a video of the speaker and inputting it into the proposed model to obtain the corresponding subtitles.Using deep learning technologies makes it easier for users to extract a large number of different features,which can then be converted to probabilities of letters to obtain accurate results.Recently proposed methods for lip reading are based on sequence-to-sequence architectures that are designed for natural machine translation and audio speech recognition.However,in this paper,a deep convolutional neural network model called the hybrid lip-reading(HLR-Net)model is developed for lip reading from a video.The proposed model includes three stages,namely,preprocessing,encoder,and decoder stages,which produce the output subtitle.The inception,gradient,and bidirectional GRU layers are used to build the encoder,and the attention,fully-connected,activation function layers are used to build the decoder,which performs the connectionist temporal classification(CTC).In comparison with the three recent models,namely,the LipNet model,the lip-reading model with cascaded attention(LCANet),and attention-CTC(A-ACA)model,on the GRID corpus dataset,the proposed HLR-Net model can achieve significant improvements,achieving the CER of 4.9%,WER of 9.7%,and Bleu score of 92%in the case of unseen speakers,and the CER of 1.4%,WER of 3.3%,and Bleu score of 99%in the case of overlapped speakers. | Amany M.Sarhan Nada M.Elshennawy Dina M.Ibrahim | 2021 | Computers, Materials & Continua2021，，8： | 0 |
