Property limits: debates on the body, nature na culture in Melanesia

A aplicação do conceito anglo-americano de propriedade está se expandindo exponencialmente. Novas formas de propriedade têm sido propostas pelas ciências da vida para a informação genética, por governos e Organizações Não Governamentais (ONGs) para o direito de poluir, e por organizações multilaterais para a cultura. Entretanto, essas demandas novas por propriedade precipitaram debates sobre os limites apropriados para regimes de propriedade. Uma conseqüência não intencional desses debates, contudo, tem sido a promoção dos conceitos anglo-americanos de corpo, natureza e cultura. São acionados exemplos da Melanésia, onde a língua das transações desafia as pressuposições que dão suporte aos modelos euroamericanos de propriedade. O artigo examina debates sobre uma patente para uma linha de célula humana, o gerenciamento da poluição de uma mina de cobre e ouro, e se a cultura pode ser apropriada

SMATASY - A program for the model independent description of the Z resonance

SMATASY is an interface for the ZFITTER package and may be used for the model independent description of the Z resonance at LEP 1 and SLC. It allows the determination of the Z mass and width and its resonance shape parameters r and j for cross-sections and their asymmetries. The r describes the peak height and j the interference of the Z resonance with photon exchange in each scattering channel and for $\sigma_T$, $\sigma_{FB}$, $\sigma_{lr}$, $\sigma_{pol}$ etc. separately. Alternatively, the helicity amplitudes for a given scattering channel may be determined. We compare our formalism with other model independent approaches. The model independent treatment of QED corrections in SMATASY is applicable also far away from the Z peak.Comment: 25 pages (LaTeX), 5 figures, 1 table, see also http://www-zeuthen.desy.de/~riemann/ or http://hpl3sn02.cern.ch/homepages/gruenew

Nonlinear time-harmonic Maxwell equations in an anisotropic bounded medium

We find solutions $E:\Omega\to\mathbb{R}^3$ of the problem \begin{eqnarray*} \left\{ \begin{aligned} &\nabla\times(\mu(x)^{-1}\nabla\times E) - \omega^2\epsilon(x) E = \partial_E F(x,E) &&\quad \text{in }\Omega\\%\newline &\nu\times E = 0 &&\quad \text{on }\partial\Omega \end{aligned} \right. \end{eqnarray*} on a bounded Lipschitz domain $\Omega\subset\mathbb{R}^3$ with exterior normal $\nu:\partial\Omega\to\mathbb{R}^3$. Here $\nabla\times$ denotes the curl operator in $\mathbb{R}^3$. The equation describes the propagation of the time-harmonic electric field $\Re\{E(x)e^{i\omega t}\}$ in an anisotropic material with a magnetic permeability tensor $\mu(x)\in\mathbb{R}^{3\times3}$ and a permittivity tensor $\epsilon(x)\in\mathbb{R}^{3\times3}$. The boundary conditions are those for $\Omega$ surrounded by a perfect conductor. It is required that $\mu(x)$ and $\epsilon(x)$ are symmetric and positive definite uniformly for $x\in\Omega$, and that $\mu,\epsilon\in L^{\infty}(\Omega,\mathbb{R}^{3\times 3})$. The nonlinearity $F:\Omega\times\mathbb{R}^3\to\mathbb{R}$ is superquadratic and subcritical in $E$, the model nonlinearity being of Kerr-type: $F(x,E)=|\Gamma(x)E|^p$ for some $2<p<6$ with $\Gamma(x)\in GL(3)$ invertible for every $x\in\Omega$ and $\Gamma,\Gamma^{-1}\in L^\infty(\Omega, \mathbb{R}^{3\times 3})$. We prove the existence of a ground state solution and of bound states if $F$ is even in $E$. Moreover if the material is uniaxial we find two types of solutions with cylindrical symmetries.Comment: to appear in J. Funct. Ana

On the Mass and Width of the Z-boson and Other Relativistic Quasistable Particles

The ambiguity in the definition for the mass and width of relativistic resonances is discussed, in particular for the case of the Z-boson. This ambiguity can be removed by requiring that a resonance's width $\Gamma$ (defined by a Breit-Wigner lineshape) and lifetime $\tau$ (defined by the exponential law) always and exactly fulfill the relation $\Gamma = \hbar/\tau$. To justify this one needs relativistic Gamow vectors which in turn define the resonance's mass M_R as the real part of the square root $\rm{Re}\sqrt{s_R}$ of the S-matrix pole position s_R. For the Z-boson this means that $M_R \approx M_Z - 26{MeV}$ and $\Gamma_R \approx \Gamma_Z-1.2{MeV}$ where M_Z and $\Gamma_Z$ are the values reported in the particle data tables.Comment: 23 page

Model-independent Representation of Electroweak Data

General model-independent expressions are developed for the polarized and unpolarized cross-sections for $e^+e^-\to f\bar f$ near the $Z^0$ resonance. The expressions assume only the analyticity of S-matrix elements. Angular dependence is included by means of a partial wave expansion. The resulting simple forms are suitable for use in fitting data or in Monte Carlo event generators. A distinction is made between model-independent and model-dependent QED corrections and a simple closed expression is given for the effect of initial-final state bremsstrahlung and virtual QED corrections.Comment: 14 pages LaTeX.

Prospects of apoptotic cell-based therapies for transplantation and inflammatory diseases.

International audienceApoptotic cell removal or interactions of early-stage apoptotic cells with immune cells are associated with an immunomodulatory microenvironment that can be harnessed to exert therapeutic effects. While the involved immune mechanisms are still being deciphered, apoptotic cell infusion has been tested in different experimental models where inflammation is deregulated. This includes chronic and acute inflammatory disorders such as arthritis, contact hypersensitivity and acute myocardial infarction. Apoptotic cell infusion has also been used in transplantation settings to prevent or treat acute and chronic rejection, as well as to limit acute graft-versus-host disease associated with allogeneic hematopoietic cell transplantation. Here, we review the mechanisms involved in apoptotic cell-induced immunomodulation and data obtained in preclinical models of transplantation and inflammatory diseases
