    We use continuation and moving hyperplane methods to prove some existence and a priori estimates for p-Laplace systems of the form { - Δp1 u = f( v ) in Ω, u = 0 on ∂Ω, { - Δp2 v = g( u ) in Ω, v = 0 on ∂Ω, where 1 (p1 - 1)(p2 - 1). We extend results obtained in Azizieh and Clément (J. Differential Equations, 179 (2002), 213-245) where the case of a single equation was considered. © 2002 Elsevier Science (USA).SCOPUS: ar.jinfo:eu-repo/semantics/publishe

    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

    Newspaper article titled "Author Claims Evidence of Second JFK Assassin." The article states that author Richard J. Whalen concluded "that there is circumstantial evidence to support the theory of a second assassin in the shooting of President John F. Kennedy.

    Also By The Same Author: AKTiveAuthor, a Citation Graph Approach to Name Disambiguation

    No full text
    The 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 text
    Jersey 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

    We 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

Several recent publications have highlighted its potential role in the functioning of the immune system. The overall objective of this study was to look into possible correlations between levels of vitamin D and inflammatory markers in sera of healthy adult women. These markers included proinflammatory cytokines (interleukin [IL]-1&beta;, IL-6, IL-8, IL-17, interferon [IFN]-&gamma;, and tumor necrosis factor [TNF]-&alpha;), anti-inflammatory cytokines (IL-4, IL-10, and IL-13), as well as C-reactive protein (CRP) as a general indicator of inflammation. Methods: Venous blood samples were collected from 118 healthy adult women and serum levels of vitamin D, CRP, proinflammatory cytokines (IL-1&beta;, IL-6, IL-8, IL-17, IFN-&gamma;, and TNF-&alpha;), and anti-inflammatory cytokines (IL-4, IL-10, and IL-13) were measured. Results: There were no significant direct correlations between serum levels of vitamin D and any of the inflammatory markers measured. However, subjects with deficient levels of vitamin D and high CRP produced significantly higher levels of the proinflammatory cytokines (TNF-&alpha; and IL-8) as compared to subjects with low CRP levels with nondeficient and deficient levels of vitamin D. Further, the anti-inflammatory/proinflammatory ratios suggest a role of vitamin D in maintaining an anti-inflammatory environment at low levels of CRP, an association that is weaker at high CRP levels in subjects with subclinical inflammatory situations. Conclusion: These data point to a possible role of vitamin D as a contributing factor in balancing cytokines toward an anti-inflammatory role in inflammatory situations. Keywords: vitamin D, cytokines, adult women, CRP, Kuwai

    Mapping the Discipline of the Olympic Games An Author-Cocitation Analysis

    No full text
    The 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

    Symmetry and Monotonicity Results for Positive Solutions of p-Laplace Systems

    No full text
    In this paper, we extend to a system of the type: [-Δp1u=f(v) in Ω, u > 0 in Ω, u=0 on ∂Ω, [-Δp2v=g(u) in Ω, v > 0 in Ω, v=0 on ∂Ω, where Ω ⊂ ℝN is bounded, the monotonicity and symmetry results of Damascelli and Pacella obtained in [5] in the case of a scalar p-Laplace equation with 1 < p < 2. For this purpose, we use the moving hyperplanes method and we suppose that f,g: ℝ → ℝ+ are increasing on ℝ+ and locally Lipschitz continuous on ℝ and p1,P2 ∈ (1,2) or p1 ∈ (1, ∞),p2 = 2.SCOPUS: ar.jinfo:eu-repo/semantics/publishe
