"Table 4" of "A study of tau decays involving eta and omega mesons."
2015
Background-subtracted $\omega\pi$ mass spectrum for the data from the ND experiment [S.I. Dolinski et al., Phys. Rep. 202 (1991) 99], plotted as open circles. The error has been set to zero if it is smaller than the point size.

$\pi^+\pi^-\pi^0$ mass distribution (two entries per event) in the $\pi^{\pm}\pi^+\pi^-\pi^0$ final state for the one-photon sample. The bin size has been chosen to display the detailed shape of the $\omega$ peak. The non-resonant contribution is represented by a simple polynomial. Non-$\tau$ background has been subtracted. The error has been set to zero if it is smaller than the point size.

Background-subtracted $\omega\pi$ mass spectrum for the data presented here, plotted as black dots. The error has been set to zero if it is smaller than the point size.
Evidence against a key role for transforming growth factor-beta1 in cytomegalovirus-induced bone marrow aplasia.
1998
During immunodeficiency after sublethal haematoablative treatment, cytomegalovirus (CMV) infection interferes with haematopoietic reconstitution and can cause lethal bone marrow (BM) aplasia. The in vivo model of murine CMV infection has identified the BM stroma as the principal target site of CMV in the haematopoietic cord. The infected cell type is the reticular stromal cell which forms the stromal network and produces essential haemopoietins, such as stem-cell factor (SCF). The expression of SCF was found to be reduced in the infected stroma, but the stromal network was not disrupted and the number of infected stromal cells was too low to explain the functional deficiency. These facts ca…
Existence, nonexistence and uniqueness of positive solutions for nonlinear eigenvalue problems
2017
We study the existence of positive solutions for perturbations of the classical eigenvalue problem for the Dirichlet $p-$Laplacian. We consider three cases. In the first the perturbation is $(p-1)-$sublinear near $+\infty$, while in the second the perturbation is $(p-1)-$superlinear near $+\infty$ and in the third we do not require asymptotic condition at $+\infty$. Using variational methods together with truncation and comparison techniques, we show that for $\lambda\in (0, \widehat{\lambda}_1)$ -$\lambda>0$ is the parameter and $\widehat{\lambda}_1$ being the principal eigenvalue of $\left(-\Delta_p, W^{1, p}_0(\Omega)\right)$ -we have positive solutions, while for $\lambda\geq \widehat{\…
Aspects de la gestion des dolmens et des tombes collectives actuels dans les sociétés de l’île de Sumba (Indonésie)
2021
L’article présente une étude ethnoarchéologique dont l’objectif est de cerner les principales caractéristiques de la pratique de la tombe collective dans les sociétés traditionnelles de l’île de Sumba (Indonésie) et de montrer comment les éléments recueillis peuvent nous conduire à modifier notre manière d’appréhender les tombes collectives du Néolithique européen. Les sociétés sélectionnées sont les dernières au monde à construire des monuments mégalithiques dans le but d’en faire des tombes collectives. La maîtrise de l’arrière-plan social et religieux et une connaissance du vécu subjectif des individus impliqués constituent ici les principaux atouts de la démarche ethnoarchéologique. Dan…
Societal premises for sustainable development in large southern cities
2005
Abstract This article examines considerations related to the societal premises of a ‘sustainable city’ in the context of large southern cities. The article also reviews some alternative concepts to ‘sustainable city’ such as ‘eco-city’ and ‘ecological city’ and examines their suitability in the South. The article proposes that the greatest challenge of environmental urban development in the South is not necessarily the lack of environmental services and infrastructure, but the societal structures reproducing unequal distribution and malfunctioning of these services. The authors’ empirical evidence and personal experience from Lagos, New Delhi, Cairo and Manila is presented to elaborate the …
Molecules and morphology reveal cryptic variation among digeneans infecting sympatric mullets in the Mediterranean.
2009
SUMMARYWe applied a combined molecular and morphological approach to resolve the taxonomic status of Saccocoelium spp. parasitizing sympatric mullets (Mugilidae) in the Mediterranean. Eight morphotypes of Saccocoelium were distinguished by means of multivariate statistical analyses: 2 of Saccocoelium obesum ex Liza spp.; 4 of S. tensum ex Liza spp.; and 2 (S. cephali and Saccocoelium sp.) ex Mugil cephalus. Sequences of the 28S and ITS2 rRNA gene regions were obtained for a total of 21 isolates of these morphotypes. Combining sequence data analysis with a detailed morphological and multivariate morphometric study of the specimens allowed the demonstration of cryptic diversity thus rejecting…
Venom gland and reservoir morphology in the Doryctinae and related braconid wasps (Insecta, Hymenoptera, Braconidae)
1992
Detailed venom reservoir and venom gland intima morphology has been investigated in reprsentatives of 84 genera and 10 subfamilies of Braconidae with particular reference to the Doryctinac, basal cyclostomes and related groups including the Opiinae, Alysiinae and Rogadinae sens. lat. Several new phylogenetically significant characters are described and illustrated. Extcnsivc secretory ductules on the primary venom duct is suggested as a synapomorphy for the subfamilies Braconinac, Doryctinae, Opiinae, Alysiinae and Gnamptodontinae. The presence of two separate venom gland insertions and their position beyond the spiral sculpture of the reservoir are suggested as synapomorphies for the subfa…
