| 4 | Splicing operation and fuzzy molecular automaton显示文摘Purpose–The purpose of this study is to develop a Turing machine or a finite automaton,which scans the input data tape in the form of DNA sequences and inspires the basic design of a DNA computer.Design/methodology/approach–This model based on a splicing system can solve fuzzy reasoning autonomously by using DNA sequences and human assisted protocols.Its hardware consists of class IIS restriction enzyme and T4 DNA ligase while the software consists of double stranded DNA sequences and transition molecules which are capable of encoding fuzzy rules.Upon mixing solutions containing these components,the automaton undergoes a cascade of cleaving and splicing cycles to produce the computational result in form of double stranded DNA sequence representing automaton’s final state.Findings–In this work,the authors have fused the idea of a splicing system with the automata theory to develop fuzzy molecular automaton in which 1,018 processors can work in parallel,requiring a trillion times less space for information storage,is 105 times faster than the existing super computer and 1,019 power operations can be performed using one Joule of energy.Originality/value–This paper presents a generalized model for biologically inspired computation in nano scale. | Kumar S.Ray Mandrita Mondal | 2012 | International Journal of Intelligent Computing and Cybernetics2012,5,2: | 0 |
| 5 | Pattern classification using fuzzy relation and genetic algorithm显示文摘Purpose–This paper aims to consider a soft computing approach to pattern classification using the basic tools of fuzzy relational calculus(FRC)and genetic algorithm(GA).Design/methodology/approach–The paper introduces a new interpretation of multidimensional fuzzy implication(MFI)to represent the author’s knowledge about the training data set.It also considers the notion of a fuzzy pattern vector(FPV)to handle the fuzzy information granules of the quantized pattern space and to represent a population of training patterns in the quantized pattern space.The construction of the pattern classifier is essentially based on the estimate of a fuzzy relation Ri between the antecedent clause and consequent clause of each one-dimensional fuzzy implication.For the estimation of Ri floating point representation of GA is used.Thus,a set of fuzzy relations is formed from the new interpretation of MFI.This set of fuzzy relations is termed as the core of the pattern classifier.Once the classifier is constructed the non-fuzzy features of a test pattern can be classified.Findings–The performance of the proposed scheme is tested on synthetic data.Subsequently,the paper uses the proposed scheme for the vowel classification problem of an Indian language.In all these case studies the recognition score of the proposed method is very good.Finally,a benchmark of performance is established by considering Multilayer Perceptron(MLP),Support Vector Machine(SVM)and the proposed method.The Abalone,Hosse colic and Pima Indians data sets,obtained from UCL database repository are used for the said benchmark study.The benchmark study also establishes the superiority of the proposed method.Originality/value–This new soft computing approach to pattern classification is based on a new interpretation of MFI and a novel notion of FPV.A set of fuzzy relations which is the core of the pattern classifier,is estimated using floating point GA and very effective classification of patterns under vague and imprecise environment is performed.This new approach to pattern classification avoids the curse of high dimensionality of feature vector.It can provide multiple classifications under overlapped classes. | Kumar S.Ray | 2012 | International Journal of Intelligent Computing and Cybernetics2012,5,4: | 0 |
| 6 | Na_2O·8TeO_2晶相的转变分解机理探索显示文摘以Na_2O-TeO_2玻璃系统中发现的一个新晶相Na_2O·8TeO_2(NT_8)为研究对象,通过热分析和X-射线衍射等分析手段,着重探讨了该晶相的形成条件和分解条件,分析了该晶相发生转变的过程和机理。结果发现该晶相在330℃下能够稳定存在,而在330~340℃之间则会分解成Na_2O·4TeO_2(NT_4)和TeO_2两种晶体。在由NT_8向NT_4和TeO_2的转变过程中出现了两个热效应,先是一个吸热反应,然后是一个放热反应,这说明在NT_8向NT_4和TeO_2的转变过程中,出现了一个中间相,该中间相为一种非晶相。作者认为,NT_8向NT_4和TeO_2的转变分为两个步骤,第一步是由NT_8向中间非晶相的转变,第二步是中间非晶相向NT_4和TeO_2的转变,而且由NT_8向中间相转变的过程与由中间相向NT_4和TeO_2转变的过程是同时进行的。 | 朱冬梅 罗发 周万城 Chandra S.Ray Delbert E.Day | 2007 | 稀有金属材料与工程2007,36,A02: | 0 |
| 7 | 不同重力环境下硼铅玻璃的二次分相现象研究显示文摘以不同落塔实验所得的硼铅玻璃试样为研究对象,通过微观形貌观察和相分析等手段,研究了硼铅玻璃的二次分相现象。结果发现,所有试样在一次分相形成富硼相和富铅相后,富硼相和富铅相都继续发生了分相,即二次分相现象。不同试样发生二次分相后的微观形貌有很大不同,这主要是由于所发生的二次分相没有遵循现有相图中的不混溶区,而是按照另外一种不混溶区进行的。在PbO-B_2O_3系统中除了已知的不混溶区以外,至少还存在有另外两个不混溶区,这两个不混溶区目前还不能准确定位,本文对这两个不混溶区在相图中的位置进行了大概的估计,而且发现不同重力条件下这些不混溶区在相同中的位置也有很大不同。 | 朱冬梅 罗发 周万城 Chandra S.Ray Delbert E.Day | 2007 | 稀有金属材料与工程2007,36,A02: | 0 |
| 8 | Geochemistry of Harappan potteries from Kalibangan and sediments in the Ghaggar River: Clues for a dying river显示文摘The ephemeral Ghaggar-Hakra River of northwestern India has always been considered to be the remnant of an ancient perennial glacier-fed river(Vedic Saraswati). The exact reason and timing of major hydrological change of this river remains speculative. The river's purported association with the zenith of the Harappan civilisation remains a conjecture because the timings of its fluvial past are still being debated. In this study we have made an attempt to resolve this issue using geochemical provenance of sediments from some dated horizons in the Ghaggar flood plain and that of the material used in the potteries from the Mature Harappan period(4600-3900 yr BP) at Kalibangan. Sampled sedimentary horizons were dated by radiocarbon and optically stimulated luminescence(OSL) methods. Results of our study from the Ghaggar alluvium indicate that the river did have glacial sources during the early Holocene. However, the data from the potteries suggest that during the Mature Harappan period, the sediments in the Ghaggar as used by the potters did not have a higher Himalayan provenance and hence, were not derived from glaciated Himalayas.These findings imply that during the time of the Mature Harappans the Ghaggar had already become a foothill-fed river. | Anirban Chatterjee Jyotiranjan S.Ray | 2018 | Geoscience Frontiers2018,9,4: | 0 |
| 9 | FAST discovery of an extremely radio-faint millisecond pulsar from the Fermi-LAT unassociated source 3FGL J0318.1+0252显示文摘High sensitivity radio searches of unassociated γ-ray sources have proven to be an effective way of finding new pulsars. Using the Five-hundred-meter Aperture Spherical radio Telescope(FAST) during its commissioning phase, we have carried out a number of targeted deep searches of Fermi Large Area Telescope(LAT) γ-ray sources. On February 27, 2018 we discovered an isolated millisecond pulsar(MSP), PSR J0318+0253, coincident with the unassociated γ-ray source 3 FGL J0318.1+0252. PSR J0318+0253 has a spin period of 5.19 ms, a dispersion measure(DM) of 26 pc cm-3 corresponding to a DM distance of about 1.3 kpc, and a period-averaged flux density of(~11±2) μJy at L-band(1.05-1.45 GHz). Among all high energy MSPs, PSR J0318+0253 is the faintest ever detected in radio bands, by a factor of at least ~4 in terms of L-band fluxes. With the aid of the radio ephemeris, an analysis of 9.6 years of Fermi-LAT data revealed that PSR J0318+0253 also displays strong γ-ray pulsations. Follow-up observations carried out by both Arecibo and FAST suggest a likely spectral turn-over around 350 MHz. This is the first result from the collaboration between FAST and the Fermi-LAT teams as well as the first confirmed new MSP discovery by FAST, raising hopes for the detection of many more MSPs. Such discoveries will make a significant contribution to our understanding of the neutron star zoo while potentially contributing to the future detection of gravitational waves, via pulsar timing array(PTA) experiments. | Pei Wang Di Li Colin J.Clark Pablo M.Saz Parkinson Xian Hou Weiwei Zhu Lei Qian Youling Yue Zhichen Pan Zhijie Liu Xuhong Yu Shanping You Xiaoyao Xie Qijun Zhi Hui Zhang Jumei Yao Jun Yan Chengmin Zhang Kwok Lung Fan Paul S.Ray Matthew Kerr David A.Smith Peter F.Michelson Elizabeth C.Ferrara David J.Thompson Zhiqiang Shen Na Wang FAST&Fermi-LAT Collaboration | 2021 | Science China(Physics,Mechanics & Astronomy)2021,64,12: | 0 |
