The global electroweak Standard Model fit after the Higgs discovery

We present an update of the global Standard Model (SM) fit to electroweak precision data under the assumption that the new particle discovered at the LHC is the SM Higgs boson. In this scenario all parameters entering the calculations of electroweak precision observalbes are known, allowing, for the first time, to over-constrain the SM at the electroweak scale and assert its validity. Within the SM the W boson mass and the effective weak mixing angle can be accurately predicted from the global fit. The results are compatible with, and exceed in precision, the direct measurements. An updated determination of the S, T and U parameters, which parametrize the oblique vacuum corrections, is given. The obtained values show good consistency with the SM expectation and no direct signs of new physics are seen. We conclude with an outlook to the global electroweak fit for a future e+e- collider.Comment: 10 pages, 7 figures. Update: added a reference.

Marktafbakening in de verzekeringssector

Dit artikel gaat over de vraag hoe in het licht van het mededingingsrecht de afbakening van de relevante markt in de verzekeringssector dient plaats te vinden. Marktafbakening speelt een belangrijke rol bij de mededingingsrechtelijke beoordeling van samenwerkingsvormen in de verzekeringssector. In deze bijdrage worden de problematische aspecten van de afbakening van verzekeringsmarkten onder het mededingingsrecht in kaart gebracht en worden in verband daarmee oplossingen en aanbevelingen gegeven

Bionomía del mosquito Aedes (Stegomyia) aegypti Ll.) En iglesias y cementerio de la ciudad de Mérida, Yucatán, México, y la identificación de arbovirus.

RESUMEN: Aedes aegypti es el vector principal de los virus dengue (VDEN), Zika (VZIK) y chikungunya (VCHIK). Aunque su bionomía es bien documentada para casas, su comportamiento es poco conocido en sitios públicos. En el presente estudio, la bionomía de Ae. aegypti fue descrito en iglesias y cementerio de la ciudad de Mérida, Yucatán. Los sitios de estudio fueron visitados cuatro veces por mes entre septiembre de 2015 y octubre de 2016. Los mosquitos adultos, fueron capturados con aspiradores de mochila. Las larvas y pupas fueron colectadas con la ayuda de pipetas de plástico. La duración del ciclo gonotrófico fue estimado con el análisis de correlación cruzada, basado en la paridad diaria de Ae. aegypti durante 25 días. La preferencia alimenticia del mosquito fue determinada con el gen del citocromo b de humanos y mamíferos. Los arbovirus fueron identificados con RT-PCR mediante la amplificación de regiones específicas de los genes de VDEN, VZIK y VCHIK. Durante todo el periodo de estudio, en las iglesias se colectaron 6,051 larvas y 315 pupas. Mientras que, en el cementerio se colectaron 8,052 larvas y 575 pupas. En cuanto los mosquitos adultos de Ae. aegypti, se colectaron en iglesias 1,380 hembras. De las cuales, 1,178 en la estación de lluvias y 202 en la de seca; la mayoría estaban alimentadas (615). En el cementerio se obtuvieron 1,648 hembras con 1,471 en periodo de lluvias y solo 177 en el de secas; la mayoría estaban sin alimentar (823). En ambos sitios de estudio, la duración del ciclo gonotrófico fue de cuatro días en temporada de lluvia y tres días en la temporada de secas. El 76% (223/292) de hembras de Ae. aegypti con alimentación reciente fueron analizadas y todas fueron identificadas con sangre de humano. En las iglesias fueron identificados dos pools de Ae. aegypti infectadas con el virus dengue (DEN-1 y 2). En el cementerio, un pool de Ae. aegypti fue infectado con dengue (DEN-1) y otro con el virus Zika. Los resultados sugieren que las iglesias y el cementerio de la ciudad de Mérida, Yucatán representan riesgo potencial en la transmisión de arbovirus. ABSTRACT: Aedes aegypti is the main vector of the dengue, Zika and chikungunya viruses. Although its bionomy is well documented in houses, their behavior is little known in public places. In the present study, the bionomy of Ae. aegypti was described in churches and cemetery of the Mérida city, Yucatán. Field work was undertaken from September 2015 to October 2016 and sampling was conducted four times per month. Resting mosquitoes were collected by using backpack-mounted aspirators. Nets, turkey basters, or pipettes were used to collect immatures from water-holding containers. Daily changes in the parous–nulliparous ratio was recorded for 25 days, and the gonotrophic cycle length was estimated by a time series analysis and the source of bloodmeal of Ae. aegypti. The host preference of Ae. aegypti was determined with the human and mammalian cytochrome b gene. Aedes aegypti females were processed for VDEN, VZIK and VCHIK identification by RT-PCR. For the entire study, 6,051 larvae and 315 pupae were collected in churches. In cemetery, 8,052 larvae and 575 pupae were collected. Of the Ae. aegypti adults, 1,380 females were collected in churches. Of which, 1,178 in the rainy season and 202 in the dry season; most were fed (615). In cemetery, 1,648 females were collected, with 1,471 in the rainy season and 177 in the dry season; most were unfed (823). In both study sites, the duration of the gonotrophic cycle was four and three days in rainy and dry season, respectively. For source of bloodmeal, we processed 76% (223/292) of Ae. aegypti females with freshly blood and all females tested were identified with human blood. In churches, two positive pools to dengue virus (DENV-1 and DENV-2) were identified. In cemetery, one pool was positive a DEN-1 and another to Zika virus. The results suggest that churches and cemetery represents potential risk of arbovirus transmission in Merida city

On the Cauchy--Rassias Inequality and Linear n-Inner Product Preserving Mappings

We prove the Cauchy-Rassias stability of linear n-inner product preserving mappings in $n$-inner product Banach spaces. We apply the Cauchy-Rassias inequality that plays an influencial role in the subject of functional equations. The inequality was introduced for the first time by Th.M.Rassias in his paper entitled: On the stability of the linear mapping in Banach spaces, Proc. Amer. Math.Soc. 72(1978), 297-300.Comment: 13 pages, Added references, and title and abstract change
