[Jamme, F.] Synchrotron SOLEIL, F-91192 Gif Sur Yvette, [email protected]; [email protected]; [email protected] audienceHyperspectral imaging in various spectral domains is used to perform in situ biochemical analysis of biological material. In the present work, two complementary microspectroscopies-mid-infrared and fluorescence-were coupled to characterise maize stem cell walls. In practice, each microspectroscopy operates with its own resolution, infrared pixels covering a 5 x 5 mu m(2) surface and fluorescence pixels a 1 x 1 mu m(2) area, making the coupling of both spectral ranges through unfolding the spectral images not straightforward. A data structure that preserved the spatial resolution in the two domains was built resulting in a two-way data table with a spatial way and a spectral way, paired to a three-way data table with two spatial ways and a spectral way. The multivariate inter-battery Tucker analysis was investigated in order to give each spectral domain a symmetric role. First, the inter-battery Tucker analysis was applied after averaging the three-way data table under the third mode to obtain a classical two-way data table. This led to work at the lowest resolution. Second, the method has been extended for coupling the three-way data table with the two-way data table. The spectral loadings were similar in both cases showing that phloem cell walls were rich in hydroxycinnamic acids and sclerenchyma cell walls in lignins. The extended version provided with fluorescence scores that preserved the spatial resolution showing more fluorescence intensity in cell junctions. The strong point of the extended inter-battery Tucker analysis is to allow the joint analysis of the two tables without altering their qualities. (c) 2011 Elsevier B.V. All rights reserved
Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Development of a combined solver to model transport and chemical reactions in catalytic wall-flow filters
No full textIn this work, we develop a non-isothermal model for diesel particulate filters including exothermic and competing chemical reactions. We begin with an isothermal, single-reaction model and we gradually increase its complexity. By comparing various models, we aim at establishing the minimum degree of complexity required to effectively model the system under investigation. Based on the numerical simulations, we conclude that isothermal models are adequate only if the temperature of the catalyst is, at all times, completely below or completely above a critical temperature. However, if the goal is to predict the critical temperature, only non-isothermal models should be used. The results with competing reactions, on the other hand, show that the presence of competing reactions does not affect significantly the overall conversion in the filter

Also By The Same Author: AKTiveAuthor, a Citation Graph Approach to Name Disambiguation
No full textThe desire for definitive data and the semantic web drive for inference over heterogeneous data sources requires co-reference resolution to be performed on those data. In particular, name disambiguation is required to allow accurate publication lists, citation counts and impact measures to be determined. This paper describes a graph-based approach to author disambiguation on large-scale citation networks. Using self-citation, co-authorship and document source analyses, AKTiveAuthor clusters papers, achieving precision of 0.997 and recall of 0.818 over a test group of eight surname clusters
John F. Kennedy telegram to Roosevelt
No full textJersey Homesteads (later the Borough of Roosevelt) was established in the 1930s as an agro-industrial cooperative community. It was established specifically for urban Jewish garment workers, many of whom had emigrated from Europe. President John F. Kennedy sent a telegram to the citizens of Roosevelt, New Jersey, apologizing for not being able to attend the memorial dedication in honor of former President Franklin Delano Roosevelt. (Jersey Homesteads became Roosevelt in 1945 in honor of the president.) President Kennedy expressed his gratitude to the people of Roosevelt for constructing the memorial, and commented that it will serve as a constant reminder of Roosevelt's good works
Logarithmic variance profiles and the corresponding f-1 spectra of temperature fluctuations in turbulent Rayleigh-Bénard convection
No full textWe report experimental results for the temperature variance 2(z) and the corresponding frequency spectra P(f) in turbulent Rayleigh-Bénard convection (RBC) in a cylindrical sample of aspect ratioT= D/L = 1:00 (D = 1:12 m is the diameter and L = 1:12 m the height). The measurements were conducted in the Rayleigh-number range 1011 < Ra < 1:35 1014 and Pr ' 0:8. For Ra = 1:35x1014, 2(z) could be described well by a logarithmic dependence on the vertical position z in a range of z 1 < z < z 2 with z 1 ' 70 and z 2 = 0:1L. Here L=(2Nu) is the thickness of a thin thermal sublayer adjacent to the horizontal plate where the heat flux (denoted by the Nusselt number Nu) is carried mostly by thermal diffusion. In the log layer, we found that the temperature spectra had a significant frequency range over which P(f) f with close to 1. As Ra decreased, increased so that the log layer became thinner. At Ra = 2:05 1011, z 2 < z 1 and therefore there was no range for a log layer. Correspondingly, the temperature spectrum near the horizontal plate did not have the f1 scaling form either

Mapping the Discipline of the Olympic Games An Author-Cocitation Analysis
No full textThe authors conducted an author cocitation analysis on prominent authors writing about the Olympics during the 1990s. Author cocitation is an established bibliometric technique that can be used to measure the relative similarities of topics written about by the cited authors. This enables a visual representation of the “intellectual space” of the discipline, in this case the Olympics, to be created for the period under review. So core and peripheral research areas are identified, along with their major contributors. The representation appears as a two-dimensional cluster-enhanced map. Subject expertise was then applied to the results to place labels on the generated clusters of authors and their topics
Study on Synthesis and Biological Activities of Novel 1,7-dihydropyrazolo[3,4-d] imidazo[1,2-f] pyrimidines
No full textAiming to synthesize new anti-inflammatory 1,7-dihydropyrazolo[3,4-d] imidazo[1,2-f] pyrimidine 5 from aminocyanopyrazole, a forthright method has been developed. It is for their anti-inflammatory, gastroprotective, analgesic, antioxidant and anticandidal activities that these compounds were screened. The investigation of the structure-activity relationships have brought about the choice of compound 6-(4-methoxyphenyl)-3-methyl-1,7-dihydropyrazolo[3,4-d]imidazo[1,2-f]pyrimidine, 5a, which revealed the most powerful activities. All novel compounds’ structures were expounded using IR, 1H NMR, 13C NMR and HRMS
