2基于变色效应的无机稀土发光材料荧光可逆调控及应用显示文摘无机稀土发光材料在照明、显示、激光和生物医学等领域有着极其广泛的应用。对荧光性能的调控有利于拓展其在温度传感、防伪识别、光开关、光存储等领域的应用。传统的荧光调控方式包括设计核壳结构、改变材料成分控制晶体场、改变稀土离子的掺杂类型或浓度从而控制能量传递等。然而,这些调控方式难以实现荧光性能的可逆调控,限制了其实际应用。对比传统的调控方式,材料在电场、热场或光场等外场刺激下可产生变色效应,通过变色效应可以实现对其荧光性能的可逆调控从而扩展其应用。本文主要综述了在电场、热场和光场刺激下,无机稀土发光材料的变色效应对其荧光性能的可逆调控及应用。白雪 徐赞 字映竹 肖代文 付丽香 何彦妮 赵和平 杨钊烁 宋友艳 HAIDER Asif Ali 向斐斐 宋志国 寸阳珂 邱建备 杨正文 2022发光学报2022,43,4:2
3Dynamics of organic carbon and nitrogen in deep soil profile and crop yields under long-term fertilization in wheat-maize cropping system显示文摘Soil organic carbon(SOC)and nitrogen(N)are two of the most important indicators for agricultural productivity.The primary objective of this study was to investigate the changes in SOC and N in the deep soil profile(up to 100 cm)and their relationships with crop productivity under the influence of long-term(since 1990)fertilization in the wheat-maize cropping system.Treatments included CK(control),NP(inorganic N and phosphorus(P)fertilizers),NPK(inorganic N,P and potassium fertilizers),NPKM(NPK plus manure),and M(manure).Crop yield and the properties of topsoil were measured yearly from 2001 to 2009.C and N contents were measured at five different depths in 2001 and 2009.The results showed that wheat and maize yields decreased between 2001 and 2009 under the inorganic fertilizer(NP and NPK)treatments.The average yield between 2001 and 2009 under the NP,NPK,NPKM,and M treatments(compared with the CK treatment)increased by 38,115,383,and 381%,respectively,for wheat and 348,891,2738,and 1845%,respectively,for maize.Different long-term fertilization treatments significantly changed coarse free particulate(cf POC),fine free particulate(ff POC),intramicroaggregate particulate(i POC),and mineral-associated(m SOC)organic carbon fractions.In the experimental years of 2001 and 2009,soil fractions occurred in the following order for all treatments:m SOC>cf POC>i POC>ff POC.All fractions were higher under the manure application treatments than under the inorganic fertilization treatments.Compared to the inorganic fertilization treatments,manure input enhanced the stocks of SOC and total N in the surface layer(0–20 cm)but decreased SOC and N in the deep soil layer(80–100 cm).This reveals the efficiency of manure in increasing yield productivity and decreasing risk of vertical loss of nutrients,especially N,compared to inorganic fertilization treatments.The findings provide opportunities for understanding deep soil C and N dynamics,which could help mitigate climate change impact on agricultural production and maintain soil health.Muhammad QASWAR LI Dong-chu HUANG Jing HAN Tian-fu Waqas AHMED Sehrish ALI Muhammad Numan KHAN Zulqarnain Haider KHAN XU Yong-mei LI Qian ZHANG Hui-min WANG Bo-ren Ahmad TAUQEER 2022Journal of Integrative Agriculture2022,21,3:2
4Intelligent Islanding Detection of Multi-distributed Generation Using Artificial Neural Network Based on Intrinsic Mode Function Feature显示文摘The integration of distributed energy resources(DERs) into distribution networks is becoming increasingly important, as it supports the continued adoption of renewable power generation, combined heat and power plants, and storage systems. Nevertheless, inadvertent islanding operation is one of the major protection issues in distribution networks connected to DERs. This study proposes an intelligent islanding detection method(IIDM) using an intrinsic mode function(IMF)feature-based grey wolf optimized artificial neural network(GWO-ANN). In the proposed IIDM, the modal voltage signal is pre-processed by variational mode decomposition followed by Hilbert transform on each IMF to derive highly involved features. Then, the energy and standard deviation of IMFs are employed to train/test the GWO-ANN model for identifying the islanding operations from other non-islanding events. To evaluate the performance of the proposed IIDM, various islanding and non-islanding conditions such as faults, voltage sag, linear and nonlinear load and switching, are considered as the training and testing datasets. Moreover, the proposed IIDM is evaluated under noise conditions for the measured voltage signal. The simulation results demonstrate that the proposed IIDM is capable of differentiating between islanding and non-islanding events without any sensitivity under noise conditions in the test signal.Samuel Admasie Syed Basit Ali Bukhari Teke Gush Raza Haider Chul Hwan Kim 2020Journal of Modern Power Systems and Clean Energy2020,8,3:2

7Papaya Ring Spot Virus:An Understanding of a Severe Positive-Sense Single Stranded RNA Viral Disease and Its Management显示文摘Viral diseases have been studied in-depth for reducing quality,yield,health and longevity of the fruit,to highlight the economic losses.Positive-sense single-stranded RNA viruses are more devastating among all viruses that infect fruit trees.One of the best examples is papaya ringspot virus(PRSV).It belongs to the genus Potyvirus and it is limited to cause diseases on the family Chenopodiaceae,Cucurbitaceae and Caricaceae.This virus has a serious threat to the production of papaya,which is famous for its high nutritional and pharmaceutical values.The plant parts such as leaves,latex,seeds,fruits,bark,peel and roots may contain the biological compound that can be isolated and used in pharmaceutical industries as a disease control.Viral disease symptoms consist of vein clearing and yellowing of young leaves.Distinctive ring spot patterns with concentric rings and spots on fruit reduce its quality and taste.The virus has two major strains P and W.The former cause disease in papaya and cucurbits while the later one in papaya.Virion comprises 94.4%protein,including a 36 kDa coat protein which is a component responsible for a non-persistent transmission through aphids,and 5.5%nucleic acid.Cross protection,development of transgenic crops,exploring the resistant sources and induction of pathogen derived resistance have been recorded as effective management of PRSV.Along with these practices reduced aphid population through insecticides and plant extracts have been found ecofriendly approaches to minimize the disease incidence.Adoption of transgenic crops is a big challenge for the success of disease resistant papaya crops.The aim of this review is to understand the genomic nature of PRSV,detection methods and the different advanced control methods.This review article will be helpful in developing the best management strategies for controlling PRSV.Muhammad Umer Mustansar Mubeen Yasir Iftikhar Haider Ali Muhammad Zafar-ul-Hye Rafia Asghar Mazhar Abbas Malik Abdul Rehman Ernesto A.Moya-Elizondo Yuejun He 2022Phyton-International Journal of Experimental Botany2022,91,10:1

16Hereditary hemochromatosis:Temporal trends,sociodemographic characteristics,and independent risk factor of hepatocellular cancer–nationwide population-based study显示文摘BACKGROUND Hereditary hemochromatosis(HH)has an increased risk of hepatocellular cancer(HCC)both due to genetic risks and iron overload as iron overload can be carcinogenic;HH impacts the increasing risk of HCC,not only through the development of cirrhosis but concerning hepatic iron deposition,which has been studied further recently.AIM To evaluate HH yearly trends,patient demographics,symptoms,comorbidities,and hospital outcomes.The secondary aim sheds light on the risk of iron overload for developing HCC in HH patients,independent of liver cirrhosis complications.The study investigated HH(without cirrhosis)as an independent risk factor for HCC.METHODS We analyzed data from National Inpatient Sample(NIS)Database,the largest national inpatient data collection in the United States,and selected HH and HCC cohorts.HH was first defined in 2011 International Classification of Disease-9th edition(ICD-9)as a separate diagnosis;the HH cohort is extracted from January 2011 to December 2019 using 275.01(ICD-9)and E83.110(ICD-10)diagnosis codes of HH.Patients were excluded from the HH cohort if they had a primary or secondary diagnostic code of cirrhosis(alcoholic,non-alcoholic,and biliary),viralhepatitis,alcoholic liver disease,non-alcoholic fatty liver disease(NAFLD),and non-alcoholic steatohepatitis(NASH).We removed these patients from the HH cohort to rule out bias or ICD-10 diagnostic errors.The HCC cohort is selected from January 2011 to December 2019 using the ICD-9 and ICD-10 codes of HCC.We selected a non-HCC cohort with the 1:1 fixed ratio nearest neighbor(greedy)propensity score method using the patients'age,gender,and race.We performed multivariate analysis for the risk factors of HCC in the HCC and non-HCC matched cohort.We further analyzed HH without cirrhosis(removing HH patients with a diagnosis of cirrhosis)as an independent risk factor of HCC after adjusting all known risk factors of HCC in the multivariate model.RESULTS During the 2011-2019 period,a total of 18031 hospitalizations with a primary or secondary diagnosis of HH(excluding liver diseases)were recorded in the NIS database.We analyzed different patients’characteristics,and we found increments in inpatient population trend with a Ptrend<0.001 and total hospital cost of care trend from$42957 in 2011 to$66152 in 2019 with a Ptrend<0.001 despite no change in Length of Stay over the last decade.The multivariate analyses showed that HH without cirrhosis(aOR,28.8;95%CI,10.4–80.1;P<0.0001),biliary cirrhosis(aOR,19.3;95%CI,13.4–27.6;P<0.0001),non-alcoholic cirrhosis(aOR,17.4;95%CI,16.5–18.4;P<0.0001),alcoholic cirrhosis(aOR,16.9;95%CI,15.9–17.9;P<0.0001),hepatitis B(aOR,12.1;95%CI,10.85–13.60;P<0.0001),hepatitis C(aOR,8.58;95%CI,8.20–8.98;P<0.0001),Wilson disease(aOR,4.27;95%CI,1.18–15.41;P<0.0001),NAFLD or NASH(aOR,2.96;95%CI,2.73–3.20;P<0.0001),alpha1-antitrypsin deficiency(aOR,2.10;95%CI,1.21–3.64;P<0.0001),diabetes mellitus without chronic complications(aOR,1.17;95%CI,1.13–1.21;P<0.0001),and blood transfusion(aOR,1.80;95%CI,1.69–1.92;P<0.0001)are independent risk factor for liver cancer.CONCLUSION Our study showed an increasing trend of in-hospital admissions of HH patients in the last decade.These trends were likely related to advances in diagnostic approach,which can lead to increased hospital utilization and cost increments.Still,the length of stay remained the same,likely due to a big part of management being done in outpatient settings.Another vital part of our study is the significant result that HH without cirrhosis is an independent risk factor for HCC with adjusting all known risk factors.More prospective and retrospective large studies are needed to re-evaluate the HH independent risk in developing HCC.Maryam Bilal Haider Ali Al Sbihi Ahmed Jamal Chaudhary Syed M Haider Ahmed Iqbal Edhi 2022World Journal of Hepatology2022,14,9:1
17Boosting the electrochemical performance and reliability of conducting polyme microelectrode via intermediate graphene for on-chip asymmetric micro-supercapacitor显示文摘High-performance anode is hurdle for on-chip planar microsupercapacitor(MSC).Polypyrrole(PPy)is a highly attractive pseudocapacitive material,but its low cycling stability,and low adhesion with current collector hinder its practicability.Herein we propose one-prong generic strategy to boost the cycling stability of PPy.For our strategy,the electrochemical deposition of multilayered reduced graphene oxide(rGO)on micropatterned Au is utilized,and the resultant rGO@Au pattern is then used for growing highly porous PPy nanostructures by facile electrochemical polymerization.The fabricated PPy anode on rGO@Au has quasi rectangular cyclic voltammetry curves up to-0.7 V and exceptional cycling stability,retaining82%of capacitance after 10,000 charge/discharge cycles in 2 M KCl electrolyte.The outstanding reliability of PPy on rGO@Au is due to the flexibility of rGO,accommodating structural pulverization and providing a promising background for the nucleation of highly porous nanostructure.Further,an all-polymer based asymmetric aqueous MSC(AMSC)is constructed with PPy anode and PEDOT cathode,which exhibited excellent electrochemical performance compared with conventional symmetric MSCs based on conducting polymers.The constructed AMSC delivered a maximum areal capacitance of 15.9 m F cm^-2(99.3 F cm^-3),high specific energy and power densities of 4.3μWh cm^-2(27.03 mWh cm^-3)and 0.36 W cm^-2(0.68 W cm^-3)at 1.4 V,respectively.The enhanced electrochemical performances can be illustrated by nucleation mechanism,in which surface topology of r GO generates a promising background for nucleation and electrochemical growth of nanoporous pseudocapacitive conducting polymers with superior interfacial contact and improved surface area.Muhammad Tahir Liang He Wei Yang Xufeng Hong Waqas Ali Haider Hui Tang Zhe Zhu Kwadwo Asare Owusu Liqiang Mai 2020Journal of Energy Chemistry2020,29,10:1

19Intelligent Breast Cancer Prediction Empowered with Fusion and Deep Learning显示文摘Breast cancer is the most frequently detected tumor that eventually could result in a significant increase in female mortality globally.According to clinical statistics,one woman out of eight is under the threat of breast cancer.Lifestyle and inheritance patterns may be a reason behind its spread among women.However,some preventive measures,such as tests and periodic clinical checks can mitigate its risk thereby,improving its survival chances substantially.Early diagnosis and initial stage treatment can help increase the survival rate.For that purpose,pathologists can gather support from nondestructive and efficient computer-aided diagnosis(CAD)systems.This study explores the breast cancer CAD method relying on multimodal medical imaging and decision-based fusion.In multimodal medical imaging fusion,a deep learning approach is applied,obtaining 97.5%accuracy with a 2.5%miss rate for breast cancer prediction.A deep extreme learning machine technique applied on feature-based data provided a 97.41%accuracy.Finally,decisionbased fusion applied to both breast cancer prediction models to diagnose its stages,resulted in an overall accuracy of 97.97%.The proposed system model provides more accurate results compared with other state-of-the-art approaches,rapidly diagnosing breast cancer to decrease its mortality rate.Shahan Yamin Siddiqui Iftikhar Naseer Muhammad Adnan Khan Muhammad Faheem Mushtaq Rizwan Ali Naqvi Dildar Hussain Amir Haider 2021Computers, Materials & Continua2021,,4:1
