The characteristics and infraciliature of a new euplotid ciliate, Euplotes qingdaoensis.n. sp., discovered from the coastal waters of Jiaozhou Bay, northern China, were studied us.n. live observation and silver impregnation. The new marine species is characterized by a slightly flattened body （90-110 um×70- 80 um, in vivo）, an adoral zone of 26-29 membranelles, 10 strong frontoventral and five transverse cirri, two caudal cirri, a s.n.le left marginal cirrus, seven dorsal kineties, a middle kinety with about 15 pairs of basal bodies, a silverline system of the double-eurystomus type, and a C-shaped macronucleus.

search for heavy sterile neutrinos in trileptons at the LHC

Chinese Physics C 2017年第10期41卷 31-36页

作者： Claudio O.Dib C.s.Kim Kechen Wang CCTVal and Department of Physics Universidad Técnica Federico Santa María Department of Physics and IPAP Yonsei University DEsY Center for Future High Energy Physics Institute of High Energy PhysicsChinese Academy of Sciences

We pres.n. a search strategy for both Dirac and Majorana sterile neutrinos from the purely leptonic decays of W^±→e^±e^±μ ν and μ^±^±e ν at the 14 TeV LHC. The discovery and exclusion limits for sterile neutrinos are shown us.n. both the Cut-and-Count（CC） and Multi-Variate Analysis（MVA） methods. We also discriminate between Dirac and Majorana sterile neutrinos by exploiting a set of kinematic observables which differ between the Dirac and Majorana cases. We find that the MVA method, compared to the more common CC method, can greatly enhance the discovery and discrimination limits. Two benchmark points with sterile neutrino mass m n =20 GeV and 50 GeV are tested. For an integrated luminosity of 3000 fb^-1, sterile neutrinos can be found with 5σ significance if heavy-to-light neutrino mixings ｜U_（ne）｜^2~｜U_（nμ）｜^2~10^-6, while Majorana vs. Dirac discrimination can be reached if at least one of the mixings is of order 10^-5.

The Use of Rank Histograms and MVL Diagrams to Characterize Ensemble Evolution in Weather Forecasting

引用

Advances in Atmospheric sciences 2010年第6期27卷 1425-1437页

作者： Jorge A.REVELLI Miguel A.RODRIGUEZ Horacio s.WIO Instituto de Fisica de Cantabria (UC and CsIC) Avda.de los Castross/nE-39005 SantanderSpain

Rank Histograms are suitable tools to assess the quality of ensembles within an ensemble prediction system or framework. By counting the rank of a given variable in the ensemble, we are basically making a sample analysis, which does.n.t allow us to distinguish if the origin of its variability is external noise or comes from chaotic sources. The recently introduced Mean to Variance Logarithmic （MVL） Diagram accounts for the spatial variability, being very s.n.itive to the spatial localization produced by infinitesimal perturbations of spatiotemporal chaotic systems. By us.n. as a benchmark a simple model subject to noise, we show the distinct information given by Rank Histograms and MVL Diagrams. Hence, the main effects of the external noise can be visualized in a graphic. From the MVL diagram we clearly observe a reduction of the amplitude growth rate and of the spatial localization （chaos suppression）, while from the Rank Histogram we observe changes in the reliability of the ensemble. We conclude that in a complex framework including spatiotemporal chaos and noise, both provide a more complete forecasting picture.

Effect of Chemical seed Treatment and BAU-Biofungicide on <i>Alternaria</i>Blight <i>(Alternaria brassicae)</i>of Mustard

引用

Agricultural sciences 2018年第5期9卷 566-576页

作者： M. Ahmed n. n. Tonu K. Hornaday F. M. Aminuzzaman M. s. M. Chowdhury M. R. Islam Department of Plant Pathology sher-e-Bangla Agricultural University Dhaka Bangladesh University of British Columbia Vancouver Canada

The efficacy of three seed treating chemicals viz. Provax 200 WP, Brine solution, Rovral 50 WP and one Biofungicide viz. BAU-Biofungicide were evaluated against Alternaria blight of mustard caused by Alternaria brassicae and Alternaria brassicicola. Three varieties viz. var. BARI-6, Tori-7 and sAU-shorisha-1 were used in this study. The field experiment was conducted in the farm of sher-e-Bangla Agricultural University, Dhaka and laboratory experiment was conducted in the seed health Laboratory, Department of Plant Pathology, sher-e-Bangla Agricultural University, Dhaka-1207 during the period from november 2008 to July 2009. Among the seed treating chemicals, Rovral 50WP showed the best performance in reducing disease incidence and severity as well as increas.n. seed yield. Application of Rovral 50 WP gave the best result in increas.n. the number of pod per plant, pod length (cm), number of branch per plant, 100 siliqua weight (g) and 1000 seed weight (g). BAU-Biofungicide also showed promis.n. performance in controlling Alternaria blight of mustard and reduced 36% and 53% disease incidence and disease severity respectively over untreated control. BAU-Biofungicide may be recommended as an alternative means of chemical fungicide such as Rovral 50 WP for controlling Alternaria blight of mustard.

Influences of Annealing Temperature and Doping Concentration on Microstructural and Optical Properties of CeO_2:sm^(3+) nanocrystals

引用

Acta Metallurgica s.n.ca(English Letters) 2015年第6期28卷 758-765页

作者： G.Vimal Kamal P.Mani P.R.Biju Cyriac Joseph n.V.Unnikris.n.n M.A.Ittyachen school of Pure and Applied Physics Mahatma Gandhi University

nanocrystals of CeO2 with different doping concentrations of sm3＋ were s.n.hesized by a novel and cost- effective method. The crystal structure, morphology and particle size were systematically investigated by X-ray diffraction, scanning electron microscopy and transmission electron microscopy. Effects of the annealing temperature and doping concentrations on the microstructural properties of the crystals were studied. X-ray diffraction analysis indicates that the cubic structure of the CeO2 is.n.t affected by the doping of sm3＋ up to a doping concentration of 20%. Different structural parameters such as lattice constant, surface area, bulk density and porosity of the crystal were determined and discussed. Microscopic images of the CeO2：sm3＋ suggest that the thermal decomposition of oxalate precursor is a suitable s.n.hesis pathway to produce uniform-sized microparticles and nanoparticles. The influences of annealing temPerature and doping concentration of sm3＋ on the optical properties of the nanocrystals were also discussed. The photoluminescence excitation spectra reveal that the charge transfer band is redshifted with increas.n. annealing temperatures. Emission attains its maximum intensity for sm3＋ concentration of 1%, and higher concentrations lead to emission quenching.

structural,electrical and optical characterization of InGan layers grown by MOVPE

We pres.n. a study on n-type ternary InGan layers grown by atmospheric pressure metalorganic vapour phase epitaxy （MOVPE） on Gan template/（0001） sapphire substrate. An investigation of the different growth conditions on n-type InxGa1-xn （x = 0.06 -- 0.135） alloys was done for a series of five samples. The structural, electrical and optical properties were characterized by high resolution x-ray diffraction （HRXRD）, Hall effect and photolumineseence （PL）. Experimental results showed that different growth conditions, namely substrate rotation （sR） and change of total H2 flow （THF）, strongly affect the properties of InGan layers. This case can be clearly observed from the analytical results. When the sR speed decreased, the HRXRD scan peak of the samples shifted along a higher angle. Therefore, increas.n. the sR speed changed important structural properties of InGan alloys such as peak broadening, values of strain, lattice parameters and defects including tilt, twist and dislocation density. From PL results it is observed that the growth conditions can be changed to control the emission wavelength and it is possible to shift the emission wavelength towards the green. Hall effect measurement has shown that the resistivity of the samples changes dramatically when THF changes.
