＜正＞ Objective: To compare coronary artery disease pattern and effects of coronary artery bypass grafting （CABG） in diabetics having left ventricular （LV） systolic dysfunction （LVD） with those in non- diabetics. Methods: The study included patients with LVD （ejection fraction （EF） less than 35% on echocardgiography） and undergoing CABG. Group - Ⅰ included diabetics and group - Ⅱ included non -diabetics. Records of coronary angiography were compared. Pre- and post CABG echocardiographic data were also compared. Results: Out of 267 patients included. 116 were in group - Ⅰ and 151 in group - Ⅱ. Relatively more patients in group - Ⅰ had significant stenosis in left anterior descending, obtuse marginal and right posterior descending artery than those in group - Ⅰ. Consistently, there was reduced LV contractility before CABG. in group -Ⅰ （EF: 27.5%） as compared to group- Ⅱ （29.5%）. However, improvement following 2 - months of CABG was greater in group - Ⅰ （EF: 35.3%） than group - Ⅱ （34.4 % ）. Reduction in LV diameters was also greater in group - Ⅰ. Conclusions: Indian diabetics having LVD and undergoing CABG are found with more stenosed coronary arteries. Diabetics gain greater improvement by CABG than non - diabetics.

Structural and photoluminescence properties of terbium-doped zinc oxide nanoparticles

引用

Chinese Physics B 2014年第5期23卷 607-611页

作者： Ningthoujam Surajkumar Singh Shougaijam Dorendrajit Singh Sanoujam dhiren Meetei Department of Physics Manipur UniversityCanchipur Department of Physics Pachhunga University CollegeCollege Veng

We present in this paper a study of the structural and photoluminescence （PL） properties of terbium （Tb） doped zinc oxide （ZnO） nanoparticles synthesized by a simple low temperature chemical precipitation method, using zinc acetate and terbium nitrate in an isopropanol medium with diethanolamine （DEA） as the capping agent at 60 ℃. The as-prepared samples were heat treated and the PL of the annealed samples were studied. The prepared nanoparticles were characterized with X-ray diffraction （XRD）. The XRD patterns show the pattern of typical ZnO nanoparticles and correspond with the standard XRD pattern given by JCPDS card No. 36-1451, showing the hexagonal phase structure. The PL intensity was enhanced due to Tb^3＋ doping, and it decreased at higher concentrations of Tb^3＋ doping after reaching a certain optimum concentration. The PL spectra of Tb^3＋ doped samples exhibited blue, bluish green, and green emissions at 460 nm （5^D3 - 7^F3）, 484 nm （5^D4 - 7^F6）, and 530 nm （5^D4 - 7^F5）, respectively, which were more intense than the emissions for the undoped ZnO sample. Based on the results, an energy level schematic diagram was proposed to explain the possible electron transition processes.

Origin and geochemical characterization of the glauconites in the Upper Cretaceous Lameta Formation, Narmada Basin, central India

引用

Journal of Palaeogeography 2018年第2期7卷 99-116页

作者： Udita Bansal Santanu Banerjee dhiren K.Ruidas Kanchan Pande Department of Earth Sciences Indian Institute of Technology Bombay

This study presents geochemical characteristics of glauconites in estuarine deposits within the Maastrichtian Lameta Formation in central India. Resting conformably over the Bagh Group, the Lameta Formation consists of ~4-5 m thick arenaceous, argillaceous and calcareous green sandstones underlying the Deccan Traps. The sandstone is friable, medium-to coarse-grained, well-sorted and thoroughly crossstratified, and contains marine fossils. Detailed petrography, spectroscopy and mineral chemistry indicates unique chemical composition of glauconite with high KO, MgO, AlOand moderate TFeO. Glauconite is formed by the replacement of K-feldspars, initially as stringers in the cleavages and fractures of feldspars. Incipient glauconite subsequently evolves fully, appearing as pellets. Fully-evolved glauconite pellets often leave tiny relics of K-feldspar. XRD exhibits characteristic peak of 10A from basal(001)reflection of glauconite, indicating the "evolved" character. The KO content of glauconites in the Lameta Formation varies from 5.51% to 8.29%, corroborating the "evolved" to "highly-evolved" maturation *** TFeOcontent of glauconite varies from 12.56% to 18.90%. The PASS-normalized-REE patterns of glauconite exhibit a "hat-shape" confirming the authigenic origin of glauconites. The slightly-negative to slightly-positive Ce anomaly value and the moderate TFeOcontent of glauconite agree well with a suboxic,estuarine condition. The replacement of K-feldspar by the glauconite contributes towards the high KO content. Compositional evolution of glauconites in the Lameta Formation is similar to those observed in many Precambrian sedimentary sequences.

On Generalized Non-commuting Graph of a Finite Ring

引用

Algebra Colloquium 2018年第1期25卷 149-160页

作者： Jutirekha Dutta dhiren K. Basnet Rajat K. Nath Department of Mathematical Sciences Tezpur University Napaam-784028 Sonitpur Assam India

Let S and K be two subrings of a finite ring R. Then the generalized non- commuting graph of subrings S, K of R, denoted by [＇S,K, is a simple graph whose vertex set is （S U K）／（CK（S） U Cs（K））, and where two distinct vertices a, b are adjacent if and only if a E S or b E S and ab ≠ ba. We determine the diameter, girth and some dominating sets for FS, K. Some connections between Fs,K and Pr（S, K） are also obtained. Further, Z-isoclinism between two pairs of finite rings is defined, and we show that the generalized non-commuting graphs of two Y_~isoclinic pairs are isomorphic under some conditions.

Relativity of Speed of Light with Speed of Universe Expansion

引用

Journal of Modern Physics 2014年第14期5卷 1332-1339页

作者： dhiren Sampat Mumbai University Mumbai India

Theory of “Relativity of speed of light with speed of universe expansion” explains relation of speed of light with speed of universe expansion. This theory provides an evidence that the time cannot be relative as stated by Theory of General Relativity. Theory of Special Relativity and Theory of General Relativity were based on two fundamental propositions i.e. constancy of speed of light and independence of physical laws (especially the constancy of speed of light) from the choice of inertial system. However, postulate of these theories is not correct. Theory of “Relativity of speed of light with speed of universe expansion” answers fundamental propositions i.e. constancy of speed of light and independence of physical laws in logical manner. This theory also explains real reason behind E = mc2.

A Quantitative Analysis of Collision Resolution Protocol for Wireless Sensor Network

引用

Journal of Software Engineering and Applications 2015年第8期8卷 361-371页

作者： Reema Patel dhiren Patel Computer Engineering Department NIT Surat India

In this paper, we present formal analysis of 2CS-WSN collision resolution protocol for wireless sensor networks using probabilistic model checking. The 2CS-WSN protocol is designed to be used during the contention phase of IEEE 802.15.4. In previous work on 2CS-WSN analysis, authors formalized protocol description at abstract level by defining counters to represent number of nodes in specific local state. On abstract model, the properties specifying individual node behavior cannot be analyzed. We formalize collision resolution protocol as a Markov Decision Process to express each node behavior and perform quantitative analysis using probabilistic model checker PRISM. The identical nodes induce symmetry in the reachable state space which leads to redundant search over equivalent areas of the state space during model checking. We use “ExplicitPRISMSymm” on-the-fly symmetry reduction approach to prevent the state space explosion and thus accommodate large number of nodes for analysis.

Evaluation of Modified Vector Space Representation Using ADFA-LD and ADFA-WD Datasets

引用

Journal of Information Security 2015年第3期6卷 250-264页

作者： Bhavesh Borisaniya dhiren Patel Computer Engineering Department NIT Surat India

Predicting anomalous behaviour of a running process using system call trace is a common practice among security community and it is still an active research area. It is a typical pattern recognition problem and can be dealt with machine learning algorithms. Standard system call datasets were employed to train these algorithms. However, advancements in operating systems made these datasets outdated and un-relevant. Australian Defence Force Academy Linux Dataset (ADFA-LD) and Australian Defence Force Academy Windows Dataset (ADFA-WD) are new generation system calls datasets that contain labelled system call traces for modern exploits and attacks on various applications. In this paper, we evaluate performance of Modified Vector Space Representation technique on ADFA-LD and ADFA-WD datasets using various classification algorithms. Our experimental results show that our method performs well and it helps accurately distinguishing process behaviour through system calls.
