| 1 | 一种使用静态分析和遗传搜索在Android恶意软件检测中搜索最优特征的方法(英文)显示文摘移动设备制造商在全球范围内快速开发各种Android版本。同时,网络罪犯也在实施各种恶意行为,例如跟踪用户活动、窃取个人数据以及实施银行诈骗。由于在日常生活中使用Android进行重要通信的人群数量庞大,这些网络罪犯从中获得了巨大非法收益。为此,安全从业者通过静态和动态分析对恶意软件进行识别。静态分析具有整体代码覆盖、低资源消耗和快速处理的优势。然而,静态分析需要最少量的特征才能对恶意软件进行有效分类。因此,我们采用基于遗传算法(GA)的遗传搜索(GS)在106个字符串中选择特征。为评估由GS确定的最佳特征,我们使用了5种机器学习分类器,分别是Na?ve Bayes(NB)、功能树(FT)、J48、随机森林(RF)和多层感知器(MLP)。在这5种分类器中,FT仅使用6种特征,获得最高准确度(95%)和最高真正率(TPR)(96.7%)。 | Ahmad FIRDAUS Nor Badrul ANUAR Ahmad KARIM Mohd Faizal Ab RAZAK | 2018 | Frontiers of Information Technology & Electronic Engineering2018，19，6： | 5 |

| 3 | Current molecular methods for the detection of hepatitis C virus in high risk group population:A systematic review显示文摘Hepatitis C virus(HCV) is an emerging infection worldwide and the numbers of persons infected are increasing every year. Poor blood transfusion methods along with unsafe injection practices are potential sources for the rapid spread of infection. Early detection of HCV is the need of the hour especially in high riskgroup population as these individuals are severely immunocompromised. Enzyme Immunoassays are the most common detection techniques but they provide no evidence of active viremia or identification of infected individuals in the antibody-negative phase and their efficacy is limited in individuals within high risk group population. Molecular virological techniques have an important role in detecting active infection with utmost specificity and sensitivity. Technologies for assessment of HCV antibody and RNA levels have improved remarkably, as well as our understanding of how to best use these tests in patient management. This review aims to give an overview of the different serological and molecular methods employed in detecting HCV infection used nowadays. Additionally, the review gives an insight in the new molecular techniques that are being developed to improve the detection techniques particularly in High Risk Group population who are severely immunocompromised. | Rushna Firdaus Kallol Saha Aritra Biswas Provash Chandra Sadhukhan | 2015 | World Journal of Virology2015，4，1： | 4 |
| 4 | Variational Mode Decomposition for Rotating Machinery Condition Monitoring Using Vibration Signals显示文摘The failure of rotating machinery applications has major time and cost effects on the industry.Condition monitoring helps to ensure safe operation and also avoids losses.The signal processing method is essential for ensuring both the efficiency and accuracy of the monitoring process.Variational mode decomposition(VMD)is a signal processing method which decomposes a non-stationary signal into sets of variational mode functions(VMFs)adaptively and non-recursively.The VMD method offers improved performance for the condition monitoring of rotating machinery applications.However,determining an accurate number of modes for the VMD method is still considered an open research problem.Therefore,a selection method for determining the number of modes for VMD is proposed by taking advantage of the similarities in concept between the original signal and VMF.Simulated signal and online gearbox vibration signals have been used to validate the performance of the proposed method.The statistical parameters of the signals are extracted from the original signals,VMFs and intrinsic mode functions(IMFs)and have been fed into machine learning algorithms to validate the performance of the VMD method.The results show that the features extracted from VMD are both superior and accurate for the monitoring of rotating machinery.Hence the proposed method offers a new approach for the condition monitoring of rotating machinery applications. | Muhd Firdaus Isham Muhd Salman Leong Meng Hee Lim Zair Asrar Ahmad | 2018 | Transactions of Nanjing University of Aeronautics and Astronautics2018，35，1： | 3 |
| 5 | Antioxidant and cytotoxic activity of Acanthus ilicifolius flower显示文摘Objective:To investigate the antioxidant and cytotoxic activity of the flower of Acanthus ilicifolius(A.ilicifolius).Methods:Antioxidant activity was determined as antiradical efficiency with diphenyl picrylhydrazil(DPPH)method and cytotoxic assay was undertaken using brine shrimp lethal toxicity test.Results:A.ilicifolius flower contained terpenoid,phenolic compounds,and alkaloid.The methanol extract of A.ilicifolius flower showed the highest antiradical efficiency(AE=1.41×10^(-3))against DPPH radicals and the highest cytotoxicity(LC_(50)=22μg/mL)against brine shrimp nauplii.Conclusions:It is suggested that active compounds of A.ilicifolius flower solved in methanol play a role to inhibit free radical activity and kill Artemia salina nauplii.The substances can be considered as potential antioxidant and cytotoxic agents as well as imminent candidate for cancer therapy. | Muhamad Firdaus Asep Awaludin Prihanto Rahmi Nurdiani | 2013 | Asian Pacific Journal of Tropical Biomedicine2013，3，1： | 3 |
| 6 | SARS-CoV-2 spike protein binds to bacterial lipopolysaccharide and boosts proinflammatory activity显示文摘There is a link between high lipopolysaccharide(LPS)levels in the blood and the metabolic syndrome,and metabolic syndrome predisposes patients to severe COVID-19.Here,we define an interaction between SARS-CoV-2 spike(S)protein and LPS,leading to aggravated inflammation in vitro and in vivo.Native gel electrophoresis demonstrated that SARS-CoV-2 S protein binds to LPS.Microscale thermophoresis yielded a of〜47 nM for the interaction.Computational modeling and all-atom molecular dynamics simulations further substantiated the experimental results,identifying a main LPS-binding site in SARS-CoV-2 S protein.S protein,when combined with low levels of LPS,boosted nuclear factor-kappa B(NF-k B)activation in monocytic THP-1 cells and cytokine responses in human blood and peripheral blood mononuclear cells,respectively.The in vitro inflammatory response was further validated by employing NF-kB reporter mice and in vivo bioimaging.Dynamic light scattering,transmission electron microscopy,and LPS-FITC analyses demonstrated that S protein modulated the aggregation state of LPS,providing a molecular explanation for the observed boosting effect.Taken together,our results provide an interesting molecular link between excessive inflammation during infection with SARS-CoV-2 and comorbidities involving increased levels of bacterial endotoxins. | Ganna Petruk Manoj Puthia Jitka Petrlova Firdaus Samsudin Ann-Charlotte Stromdahl Samuel Cerps Lena Uller Sven Kjellstrom Peter J.Bond Artur Schmidtchen | 2020 | Journal of Molecular Cell Biology2020，12，12： | 3 |
| 7 | Flapping wing micro-aerial-vehicle: Kinematics, membranes, and flapping mechanisms of ornithopter and insect flight显示文摘The application of biomimetics in the development of unmanned-aerial-vehicles(UAV)has advanced to an exceptionally small scale of nano-aerial-vehicles(NAV), which has surpassed its immediate predecessor of micro-aerial-vehicles(MAV), leaving a vast range of development possibilities that MAVs have to offer. Because of the prompt advancement into the NAV research development, the true potential and challenges presented by MAV development were never solved,understood, and truly uncovered, especially under the influence of transition and low Reynolds number flow characteristics. This paper reviews a part of previous MAV research developments which are deemed important of notification; kinematics, membranes, and flapping mechanisms ranges from small birds to big insects, which resides within the transition and low Reynolds number regimes. This paper also reviews the possibility of applying a piezoelectric transmission used to produce NAV flapping wing motion and mounted on a MAV, replacing the conventional motorized flapping wing transmission. Findings suggest that limited work has been done for MAVs matching these criteria. The preferred research approach has seen bias towards numerical analysis as compared to experimental analysis. | Mohd Firdaus Bin Abas Azmin Shakrine Bin Mohd Rafie Hamid Bin Yusoff Kamarul Arifin Bin Ahmad | 2016 | Chinese Journal of Aeronautics2016，29，5： | 3 |
| 8 | Cold Plasma:A Potential Alternative for Rice Grain Postharvest Treatment Management in Malaysia显示文摘Use of pesticides,herbicides and fertilizers is among the techniques to control insect pests and fungal pathogens.However,the technique is the major contributor to severe environmental implications in terms of air,water and soil pollution.Besides,variable inconsistency becomes an important issue in the implementation of inclined bed dryers,leading to significant rice grain loss.Cold plasma technology has been widely proposed as a potential alternative for rice grain postharvest treatment management due to the presence of generated ionised gas that eventually produces reactive oxygen species or reactive nitrogen species.These species are used to decontaminate foodborne pathogens,mycotoxins and bacterial diseases.This review explores the current literature regarding cold plasma treatment technology,focusing on its efficiency as the microbial decontamination medium and insect pest mortality medium,and on the enhancement functional,nutritional and cooking properties,especially in rice grains.Previous studies have successfully demonstrated the ability of cold plasma treatment to significantly reduce the microbial count of foodborne pathogens,detoxify mycotoxins,and control seedborne rice seedling bacterial diseases.Previous studies have also proved that the implementation of cold plasma technology in postharvest management should be seriously considered for improving rice grain quantity and quality in Malaysia. | Mohd Fadthul Ikmal MISNAL Norizah REDZUAN Muhamad Nor Firdaus ZAINAL Norhayati AHMAD Raja Kamarulzaman RAJA IBRAHIM Linda AGUN | 2022 | Rice science2022，29，1： | 2 |
