The IFN-γ-Inducible GTPase, Irga6, Protects Mice against Toxoplasma gondii but Not against Plasmodium berghei and Some Other Intracellular Pathogens
2011
Clearance of infection with intracellular pathogens in mice involves interferon-regulated GTPases of the IRG protein family. Experiments with mice genetically deficient in members of this family such as Irgm1(LRG-47), Irgm3(IGTP), and Irgd(IRG-47) has revealed a critical role in microbial clearance, especially for Toxoplasma gondii. The in vivo role of another member of this family, Irga6 (IIGP, IIGP1) has been studied in less detail. We investigated the susceptibility of two independently generated mouse strains deficient in Irga6 to in vivo infection with T. gondii, Mycobacterium tuberculosis, Leishmania mexicana, L. major, Listeria monocytogenes, Anaplasma phagocytophilum and Plasmodium …
Efficacy and safety of irinotecan-based chemotherapy for advanced colorectal cancer outside clinical trials: an observational study.
2010
Background: This prospective observational study in typical community-based outpatient clinics evaluated the efficacy and toxicity of weekly and biweekly irinotecan-based chemotherapies and their compatibility depending on age. Methods: 601 patients with advanced or metastatic colorectal cancer receiving first-, second-, or third-line irinotecanbased therapy were regularly analyzed for response and toxicity until the end of therapy. Results: The median age was 65 (28–87) years, approximately one-third of the patients were ≥70 years old. Of all patients, 405 were treated weekly and 68 biweekly. Median overall survival (OS) for first-line therapy was 26.5 months for the <70-year-old patients …
Project Selection by Constrained Fuzzy AHP
2004
The selection of a project among a set of possible alternatives is a difficult task decision makers have to face. Difficulties in selecting a project arise because of the different goals involved and because of the large number of attributes to consider. Our approach is based upon a fuzzy extension of the Analytic Hierarchy Process (AHP). This paper focuses on the constraints that have to be considered within fuzzy AHP in order to take in account all the available information. This study demonstrates that by considering all the information deriving from the constraints better results in terms of certainty and reliability can be achieved.
Adaptive type-2 fuzzy logic control of a bioreactor
2010
Two adaptive type-2 fuzzy logic controllers with minimum number of rules are developed and compared by simulation for control of a bioreactor in which aerobic alcoholic fermentation for the growth of Saccharomyces cerevisiae takes place. The bioreactor model is characterized by nonlinearity and parameter uncertainty. The first adaptive fuzzy controller is a type-2 fuzzy-neuro-predictive controller (T2FNPC) that combines the capability of type-2 fuzzy logic to handle uncertainties, with the ability of predictive control to predict future plant performance making use of a neural network model of the nonlinear system. The second adaptive fuzzy controller is instead a self-tuning type-2 PI cont…
Experimental Comparison of Type-1 and Type-2 Fuzzy Logic Controllers for the Control of Level and Temperature in a Vessel
2011
Abstract The objective of this experimental study is to compare the performance of type-1 and type-2 fuzzy logic controllers on a real system where the control of liquid level and temperature are considered. By the use of genetic algorithms it is possible to optimize the fuzzy sets of each fuzzy controller assuring high control performance. The experimental results show that a better control in terms of robustness can be achieved by type-2 fuzzy logic controllers.
Solving type-2 assembly line balancing problem with fuzzy binary linear programming
2013
This paper deals with the use of fuzzy set theory as a viable alternative method for modelling and solving the stochastic assembly line balancing problem. This paper presents a fuzzy extension of the simple assembly line balancing problem of type 2 SALBP-2 with fuzzy job processing times since uncertainty, variability, and imprecision are often occurred in real-world production systems. The job processing times are formulated by triangular fuzzy membership functions using their statistical distributions. This study proposes to solve a Fuzzy Binary Linear Problem FBLP with fuzzy coefficients in the objective function and in a constraint. Finally, the effect of the unbalancing of a station in…
Algebraic (2, 2)-transformation groups
2009
This paper contains the more significant part of the article with the same title that will appear in the Volume 12 of Journal of Group Theory (2009). In this paper we determine all algebraic transformation groups $G$, defined over an algebraically closed field $\sf k$, which operate transitively, but not primitively, on a variety $\Omega$, provided the following conditions are fulfilled. We ask that the (non-effective) action of $G$ on the variety of blocks is sharply 2-transitive, as well as the action on a block $\Delta$ of the normalizer $G_\Delta$. Also we require sharp transitivity on pairs $(X,Y)$ of independent points of $\Omega$, i.e. points contained in different blocks.
Reminiscencias del ¨servus callidus¨ plautino y terenciano en la caracterización del ribaldo del ¨Libro del cavallero Zifar¨
2018
El presente estudio gira en torno al Libro del cavallero Zifar, obra anónima datada a comienzos del siglo xiv y calificada como un curio-so ejemplo de libro de caballerías. Me centro en la caracterización del personaje de Ribaldo, el fiel y astuto escudero que acompaña y aconseja al protagonista Zifar a lo largo de muchas de sus aventuras, y lo hago desde el punto de vista de su posible configuración a partir del modelo de las comedias de la palliata latina de Plauto y Terencio, con el fin de establecer algunos paralelismos entre el servus callidus que actúa en la comedia latina y el ribaldo del Libro del cavallero Zifar.
Análisis de dos relatos maravillosos del ¨Libro del cavallero Zifar¨
2018
En el presente trabajo nos proponemos estudiar la relación entre dos episodios presentes en la primera novela castellana, el Libro del Cavallero Zifar, y la tradición del maravilloso de influencia bretona. Partiremos para ello de un análisis comparativo de ambos episo-dios y el esquema del relato maravilloso propuesto por L. Harf-Lancner. Una vez establecidos los paralelismos oportunos, trataremos de ampliar el marco de comparación y comprender la presencia de estos elementos bretones en la literatura castellana desde una perspectiva más general.
El cuento de senderos que se bifurcan. El Noble cuento del enperador Carlos Maynes y sus encrucijadas genéricas
2016
International audience; Tras un breve balance del estado de la cuestión en cuanto a las fuentes del Carlos Maynes, este trabajo estudia los cambios genéricos que obran en este relato: paso de «cantar de gesta» a «cuento maravilloso», es decir a relato en prosa de aventuras caballerescas; del docere al delectare; del tema de las reinas injustamente acusadas a la problemática del buen gobierno en el espacio conflictivo de la corte. Estos cruces temáticos nuevos del Carlos Maynes abren, además, muchas puertas: nuevos grupos sociales pueden entrar a formar parte del espacio literario –con la creación de personajes como los villanos Barroquer y Griomoart–, pero también nuevos tonos y estilos com…
