We study the maximum weighted independent-set problem on interval graphs with uncertainty on the vertex weights. We use the absolute robustness criterion and the min-max regret criterion to evaluate solutions. For a discrete scenario set, we nd that the problem is NP-hard for each of the robustness criteria; we also provide pseudo-polynomial time algorithms when there is a constant number of scenarios and show that the problem is strongly NP-hard when the set of scenarios is unbounded. When the scenario set is a Cartesian product, we prove that the problem is equivalent to a maximum weighted independent-set problem on the same interval graph but without uncertainty for the rst objective function and that the scenario set can be reduced for the second objective function.

Die Protagonisten der gesellschaftlichen Reformbewegungen der zweiten Hälfte des 20. Jahrhunderts überschreiten zur Zeit traditionelle Altersgrenzen. Sah Gottfried Benn noch „Altern als Problem des Künstlers“, so stellt sich aktuell, nicht nur aus demographischen Gründen, die Frage nach dem „Altern der Avantgarden“ als Problem der Mehrheitsgesell-schaft: Wie konzipieren und diskursivieren die Nachkriegs-Avantgarden, die auf ästheti-sche und soziale Progression abzielten, Altern? Im Altersstil der Avantgarden, ihren Schreibweisen, Lebensformen und Gesellschafts-entwürfen kondensiert sich ein Projekt des Alterns, das in der Verbindung von Kunst und Lebenswelt die historischen Avantgarden fortzuführen verspricht. Doch welchen systemi-schen Platz und ästhetischen Rang kann der Prozess des Alterns in Wertehorizonten einnehmen, innerhalb deren Jugendlichkeit als Voraussetzung der Erneuerung gilt? Was nutzt es, als Avantgarde der Mehrheit voraus zu sein in einer Lebenssituation, die statt durch Zukunftsoffenheit durch Zukunftslosigkeit charakterisiert ist? Der Band untersucht Denk- und Stilfiguren, Erzählmodelle und Bildentwürfe, die den immanenten Widerspruch ‚alternder Avantgarden‘ aufgreifen und in unterschiedlichen Konzepten, Medien und Textformen umsetzen: Altern als Kanonisierung im Mainstream (68er), als Selbsthistorisierung (Frauenbewegung), als Subversion und Resignation (DDR-Avantgarden nach der Wiedervereinigung), als Frage der Halbwertszeit der digitalen Avantgarde und der ‚neuen‘ Medien (Internet und Buchmarkt), als Verdrängungskampf der Generationen (Literaturkritik), als Grenzgang zwischen gesellschaftspolitischer Liberalität und ästhetischer Belastbarkeit (hedonistisch-selbstbewusste Pop-Generation), schließlich: als Prozess im Spannungsverhältnis von progressiver Gesellschaftspolitik und konservativer Geschmacksästhetik.

Symbiotic bacteria are known to play important roles in the biology of insects, but the current knowledge of bacterial communities associated with mosquitoes is very limited and consequently their contribution to host behaviors is mostly unknown. In this study, we explored the composition and diversity of mosquito-associated bacteria in relation with mosquitoes’ habitats. Wild Aedes albopictus and Aedes aegypti were collected in three different geographic regions of Madagascar. Culturing methods and denaturing gradient gel electrophoresis (DGGE) and sequencing of the rrs amplicons revealed that Proteobacteria and Firmicutes were the major phyla. Isolated bacterial genera were dominated by Bacillus, followed by Acinetobacter, Agrobacterium and Enterobacter. Common DGGE bands belonged to Acinetobacter, Asaia, Delftia, Pseudomonas, Enterobacteriaceae and an uncultured Gammaproteobacterium. Double infection by maternally inherited Wolbachia pipientis prevailed in 98% of males (n = 272) and 99% of females (n = 413); few individuals were found to be monoinfected withWolbachia wAlbB strain. Bacterial diversity (Shannon–Weaver and Simpson indices) differed significantly per habitat whereas evenness (Pielou index) was similar. Overall, the bacterial composition and diversity were influenced both by the sex of individuals and by the environment inhabited by the mosquitoes; the latter might be related to both the vegetation and the animal host populations that Aedes used as food sources.

How I explore : ventricular arrhythmhmias in athletes <br />SUMMARY : Documented ventricular tachyarrhythmias or related symptoms need meticulous cardiac investigations. The mechanism of ventricular arrhythmia must be defined. The prognosis is related to underlying cardiac electrical or structural disorders. In the absence of cardiovascular abnormalities, the prognosis is good. No disqualification to competitive activity is required in most cases. Assessment of the risk of sudden death remains a continuing challenge in athletes. This article reviews the diagnostic and therapeutic approaches of ventricular arrhythmias encountered in trained athletes. [less ▲]

ATP-gated P2X1 ion channels contribute to arterial thrombosis by amplifying platelet activation. In the search for novel anti-platelet strategies, targeting P2X1 ion channels is appealing. However, in this study we found that lack or inhibition of P2X1 channels enhanced neutrophil respiratory burst activity ex vivo. <br />To study the consequence of P2X1 deficiency on neutrophil function in vivo, P2X1-/- mice were used in a model of endotoxin-induced sepsis. Upon injection of lipopolysaccharides (LPS), plasma myeloperoxidase (MPO) concentrations reached higher levels in the P2X1-/- mice, and circulating neutrophils expressed higher levels of surface CD11b compared to wild-type mice. Neutrophil relocalization into the lungs of LPS-treated P2X1-/- mice was also significantly augmented, reflecting a higher activation state of P2X1-/- neutrophils under conditions of sepsis. Accordingly, more extensive lipid peroxidation was observed in the liver of LPS-treated P2X1-/- mice, indicative of exaggerated oxidative damage. Concomitantly, the levels of thrombin-antithrombin complexes were higher in the plasma of LPS-treated P2X1-/- mice and thrombocytopenia was worsened as compared to wild type mice. Elevated numbers of microthrombi were also found in the lungs of these mice. These observations coincided with a higher susceptibility of P2X1-/- mice to LPS-induced septic shock than wild type animals. <br />Our results strongly suggest that P2X1 ion channels play a protective role in sepsis by negatively regulating systemic neutrophil activation, thereby limiting oxidative damage, activation of coagulation and platelet accumulation into the lungs. Therefore, since antagonists of P2X1 ion channels may not only target platelets but also affect neutrophils, inhibiting these channels in the highly inflammatory environment of severe sepsis or of acute coronary syndromes might be detrimental.

Lake Kivu is a deep meromictic and oligotrophic tropical African lake with a permanent thermal- and haline stratification with huge accumulations of dissolved CO2 and CH4 (ca. 300 km3 and 60 km3, respectively) in the deep anoxic monimolimnion (from 60 o 480 m depth). Although there are a wealth of information on the ecology of small eukaryotes and their trophic role on Kivu, available information on prokaryotic planktonic assemblages is scarce. Molecular analysis of archaeal and bacterial communities showed a vertical segregation imposed by the permanent redoxcline. In relation to Bacteria, Actinobacteria, Betaproteobacteria, Green Sulfur Bacteria and Bacteroidetes were the most commonly retrieved groups. For Archaea, a marked dominance of Thaumarchaeota and Crenarchaeota (75% of all archaeal OTUs) over Euryarchaeota was observed. In the anoxic hypolimnion, Euryarchaoeta (Methanosarcinales and Methanocellales) lineages together with Miscellaneous Crenarchaeotic Group phylotypes were mainly recovered. In turn, Thaumarchaeota phylotypes were recovered in oxic and suboxic waters. CARDFISH analyses over the first 100 m revealed the dominance of Bacteria (51.4% – 95.7% of DAPI-stained cells), especially Actinobacteria (epilimnion), Betaproteobacteria (oxic-anoxic interface) and Bacteroidetes (upper hypolimnion), over Archaea (1.0% – 4.5%; maximum abundances at the oxic-anoxic interface). In turn, flow cytometry evidenced the dominance of HNA cells in the euphotic layer, whereas the proportion of LNA cells increased with depth. HNA and LNA populations were still observed in the anoxic hypolimnion suggesting facultative or strict anaerobic metabolisms. The detection of distinct depth maxima of nitrate, nitrite, archaeal amoA and Marine Thaumarchaeota 16S gene copy numbers together with regularly detection of deep maxima of 3H-Thymidine uptake, and the presence of low-light adapted GSB species point towards a strong link of N, C, and S cycles in the redoxcline of Lake Kivu.
