| 1 | 黄斑色素光学密度、中央黄斑厚度与体重指数的关系(英文)显示文摘目的:评估黄斑色素光学密度(MPOD)、中央黄斑厚度与体重指数(BMI)的关系。方法:这是一项在单一机构中进行比较的横断面研究。本研究共纳入210名符合入选标准的志愿者。使用黄斑色素筛选剂II对受试者MPOD进行测量。使用SD Cirrus OCT测量中央黄斑厚度。记录所有眼MPOD和OCT信息。使用Microsoft~?Excel,SPSS和R进行数据分析。结果:MPOD和中央黄斑厚度之间呈明显正相关(r=0.42,P<0.01)。同时,MPOD和BMI之间呈明显负相关(r=-0.23,P<0.01)。结论:研究得出,MPOD和中央黄斑厚度之间呈明显正相关。还需要进一步研究中央凹的详细结构及其与MPOD的关系。研究发现了MPOD与BMI之间呈明显正相关,且得出BMI的降低可能会增加黄斑色素的密度,这有助于预防年龄相关性黄斑变性(ARMD)。 | Lee Hong Nien Fazliana Ismail Rafidah Sudarno Angela Loo Voon Pei Visvaraja Subrayan | 2019 | 国际眼科杂志2019，19，5： | 3 |
| 2 | Adaptive green traffic signal controlling using vehicular communication显示文摘The importance of using adaptive traffic signal control for figuring out the unpredictable traffic congestion in today's metropolitan life cannot be overemphasized. The vehicular ad hoc network(VANET), as an integral component of intelligent transportation systems(ITSs), is a new potent technology that has recently gained the attention of academics to replace traditional instruments for providing information for adaptive traffic signal controlling systems(TSCSs). Meanwhile, the suggestions of VANET-based TSCS approaches have some weaknesses:(1) imperfect compatibility of signal timing algorithms with the obtained VANET-based data types, and(2) inefficient process of gathering and transmitting vehicle density information from the perspective of network quality of service(Qo S). This paper proposes an approach that reduces the aforementioned problems and improves the performance of TSCS by decreasing the vehicle waiting time, and subsequently their pollutant emissions at intersections. To achieve these goals, a combination of vehicle-to-vehicle(V2V) and vehicle-to-infrastructure(V2I) communications is used. The V2 V communication scheme incorporates the procedure of density calculation of vehicles in clusters, and V2 I communication is employed to transfer the computed density information and prioritized movements information to the road side traffic controller. The main traffic input for applying traffic assessment in this approach is the queue length of vehicle clusters at the intersections. The proposed approach is compared with one of the popular VANET-based related approaches called MC-DRIVE in addition to the traditional simple adaptive TSCS that uses the Webster method. The evaluation results show the superiority of the proposed approach based on both traffic and network Qo S criteria. | Erfan SHAGHAGHI Mohammad Reza JABBARPOUR Rafidah MD NOOR Hwasoo YEO Jason J.JUNG | 2017 | Frontiers of Information Technology & Electronic Engineering2017，18，3： | 3 |

| 7 | 对于非酒精性脂肪肝病的认识——基于亚洲人群的研究显示文摘背景和目的:非酒性脂肪肝病(NAFLD)是最常见的慢性肝病,同时也是代谢综合征的一项危险因素。NAFLD在全球范围内的患病率基于地域差异在5%~30%不等。尽管流行病学资料显示代谢相关性疾病的患病率在新加坡呈快速增长,但对于该地区NAFLD的数据却十分有限。本研究旨在了解新加坡NAFLD的患病率及公众对该病的认识。方法:本研究是一项横断面观察研究,旨在评估NAFLD患者的人口统计学、人体测量学及临床资料,研究对象来自于一项胃肠公众论坛的参会者。NAFLD的诊断基于超声学标准;代谢综合征的诊断则基于国际糖尿病联盟的指南。通过自行设计的调查问卷来了解大家对NAFLD这种疾病的看法。结果:共有227名研究对象纳入研究,其中40%被诊断为NAFLD。相对于那些非NAFLD人群,NAFLD者男性居多,年龄更大,体质指数更高,腰围更宽,患代谢性综合征的比例更高(均P<0.05)。尽管有71.2%的研究对象之前听说过NAFLD,但其中仅25.4%认为自己具有NAFLD的风险。有无代谢风险因素者对NAFLD的认识差不多(P>0.05)。值得注意的是,75.6%的具有代谢危险因素者,并不认为自己存在NAFLD风险。结论:我们的研究显示NAFLD在新加坡具有较高的患病率,包括在那些非肥胖人群中。考虑到人们对NAFLD的发生风险认识不足,有必要加强公众教育,以提高人们对NAFLD的认识。 | George B.B.Goh Clarence Kwan Sze Ying Lim Nanda KK Venkatanarasimha Rafidah Abu-Bakar Thinesh L Krishnamoorthy Hang Hock Shim Kiang Hiong Tay Wan Cheng Chow | 2016 | Gastroenterology Report2016，4，2： | 1 |

| 14 | Hot-wire chemical vapor deposition low-loss hydrogenated amorphous silicon waveguides for silicon photonic devices显示文摘We demonstrate low-loss hydrogenated amorphous silicon(a-Si:H) waveguides by hot-wire chemical vapor deposition(HWCVD). The effect of hydrogenation in a-Si at different deposition temperatures has been investigated and analyzed by Raman spectroscopy. We obtained an optical quality a-Si:H waveguide deposited at 230°C that has a strong Raman peak shift at 480 cm^(-1), peak width(full width at half-maximum) of 68.9 cm^(-1), and bond angle deviation of 8.98°. Optical transmission measurement shows a low propagation loss of 0.8 dB/cm at the1550 nm wavelength, which is the first, to our knowledge, report for a HWCVD a-Si:H waveguide. | SWE Z.OO ANTULIO TARAZONA ALI Z.KHOKHAR RAFIDAH PETRA YOHANN FRANZ GORAN Z.MASHANOVICH GRAHAM T.REED ANNA C.PEACOCK HAROLD M.H.CHONG | 2019 | Photonics Research2019，7，2： | 0 |
| 15 | Morphology and dielectric properties of single sample Ni_(0.5)Zn_(0.5)Fe_(2)O_(4)nanoparticles prepared via mechanical alloying显示文摘Nickel-zinc ferrite nanoparticles are important soft magnetic materials for high and low frequency device application and good dielectric materials.Nickel-zinc ferrite nanoparticles with composition Ni_(0.5)Zn_(0.5)Fe_(2)O_(4)were prepared using mechanical alloying to analyze the effect of sintering temperature on microstructure evolution of a single sample with dielectric properties.The single sample with nanosized pellet was sintered from 600℃to 1200℃and analyzed by X-ray diffraction(XRD)to investigate the phases of the powders and by field emission scanning electron microscopy(FESEM)for the morphology and microstructure analyses.Dielectric properties such as dielectric constant(e″)and dielectric loss(e′)were studied as functions of frequency and temperature for Ni_(0.5)Zn_(0.5)Fe_(2)O_(4).The dielectric properties of the sample were measured using HP 4192A LF impedance analyzer in the low frequency range from 40 Hz to 1 MHz and at temperature ranging from 30℃to 250℃.The results showed that single phase Ni_(0.5)Zn_(0.5)Fe_(2)O_(4)cannot be formed by milling alone and therefore requires sintering.The crystallization of the ferrite sample increased with increasing sintering temperature,while the porosity decreased and the density and average grain size increased.Evolution of the microstructure resulted in three activation energies of grain growth,where above 850℃there was a rapid grain growth in the microstructure.Dielectric constant and loss factor decreased with the increase in frequency.The optimum sintering temperature of Ni_(0.5)Zn_(0.5)Fe_(2)O_(4)was found to be 900℃which had high dielectric constant and low dielectric loss. | Rafidah HASSAN Jumiah HASSAN Mansor HASHIM Suriati PAIMAN Raba′ah Syahidah AZIS | 2014 | Journal of Advanced Ceramics2014，3，4： | 0 |

| 17 | Unicast routing protocols for urban vehicular networks:review, taxonomy, and open research issues显示文摘Over the past few years, numerous traffic safety applications have been developed using vehicular ad hoc networks(VANETs). These applications represent public interest and require network-wide dissemination techniques. On the other hand, certain non-safety applications do not require network-wide dissemination techniques.Such applications can be characterized by their individual interest between two vehicles that are geographically apart. In the existing literature, several proposals of unicast protocols exist that can be used for these non-safety applications. Among the proposals, unicast protocols for city scenarios are considered to be most challenging.This implies that in city scenarios unicast protocols show minimal persistence towards highly dynamic vehicular characteristics, including mobility, road structure, and physical environment. Unlike other studies, this review is motivated by the diversity of vehicular characteristics and difficulty of unicast protocol adaption in city scenarios.The review starts with the categorization of unicast protocols for city scenarios according to their requirement for a predefined unicast path. Then, properties of typical city roads are discussed, which helps to explore limitations in efficient unicast communication. Through an exhaustive literature review, we propose a thematic taxonomy based on different aspects of unicast protocol operation. It is followed by a review of selected unicast protocols for city scenarios that reveal their fundamental characteristics. Several significant parameters from the taxonomy are used to qualitatively compare the reviewed protocols. Qualitative comparison also includes critical investigation of distinct approaches taken by researchers in experimental protocol evaluation. As an outcome of this review, we point out open research issues in unicast routing. | Syed Adeel Ali SHAH Muhammad SHIRAZ Mostofa Kamal NASIR Rafidah Binti MD NOOR | 2014 | Journal of Zhejiang University-Science C(Computers and Electronics)2014，15，7： | 0 |
| 18 | A cooperative heterogeneous vehicular clustering framework for显示文摘Heterogeneous vehicular clustering integrates multiple types of communication networks to work efficiently for various vehicular applications.One popular form of heterogeneous network is the integration of long-term evolution(LTE)and dedicated short-range communication.The heterogeneity of such a network infrastructure and the non-cooperation involved in sharing cost/data are potential problems to solve.A vehicular clustering framework is one solution to these problems,but the framework should be formally verified and validated before being deployed in the real world.To solve these issues,first,we present a het-erogeneous framework,named destination and interest-aware clustering,for vehicular clustering that integrates vehicular ad hoc networks with the LTE network for improving road traffic efficiency.Then,we specify a model system of the proposed framework.The model is formally verified to evaluate its performance at the functional level using a model checking technique.To evaluate the performance of the proposed framework at the micro-level,a heterogeneous simulation environment is created by integrating state-of-the-art tools.The comparison of the simulation results with those of other known approaches shows that our proposed framework performs better. | Iftikhar AHMAD Rafidah Md NOOR Zaheed AHMED Umm-e-HABIBA Naveed AKRAM Fausto Pedro GARCIA MARQUEZ | 2021 | Frontiers of Information Technology & Electronic Engineering2021，22，9： | 0 |
| 19 | Deep Reinforcement Learning for Addressing Disruptions in Traffic Light Control显示文摘This paper investigates the use of multi-agent deep Q-network(MADQN)to address the curse of dimensionality issue occurred in the traditional multi-agent reinforcement learning(MARL)approach.The proposed MADQN is applied to traffic light controllers at multiple intersections with busy traffic and traffic disruptions,particularly rainfall.MADQN is based on deep Q-network(DQN),which is an integration of the traditional reinforcement learning(RL)and the newly emerging deep learning(DL)approaches.MADQN enables traffic light controllers to learn,exchange knowledge with neighboring agents,and select optimal joint actions in a collaborative manner.A case study based on a real traffic network is conducted as part of a sustainable urban city project in the Sunway City of Kuala Lumpur in Malaysia.Investigation is also performed using a grid traffic network(GTN)to understand that the proposed scheme is effective in a traditional traffic network.Our proposed scheme is evaluated using two simulation tools,namely Matlab and Simulation of Urban Mobility(SUMO).Our proposed scheme has shown that the cumulative delay of vehicles can be reduced by up to 30%in the simulations. | Faizan Rasheed Kok-Lim Alvin Yau Rafidah Md Noor Yung-Wey Chong | 2022 | Computers, Materials & Continua2022，，5： | 0 |
