In this brief report we show that tadpole diagrams due to KK modes of the graviton and radion do not contribute to the vectorial isospin breaking ρ parameter. Our result is fairly general and it holds both for ADD and RS type scenarios. It shows that the difference between the results of different publications on this subject is not due to some of them not having considered tadpole diagrams in ...

Male calls of the katydid Neoconocephalus triops exhibit substantial developmental plasticity in two parameters: (i) calls of winter males are continuous and lack the verse structure of summer calls and (ii) at equal temperatures, summer males produce calls with a substantially higher pulse rate than winter males. We raised female N. triops under conditions that reliably induced either summer o...

Although many similarities in arthropod CNS development exist, differences in axonogenesis and the formation of midline cells, which regulate axon growth, have been observed. For example, axon growth patterns in the ventral nerve cord of Artemia franciscana differ from that of Drosophila melanogaster. Despite such differences, conserved molecular marker expression at the midline of several arth...

A bstract We examine the mechanism of moduli stabilization by fluxes in limit a large number moduli. conjecture that one cannot stabilize all complex-structure F-theory at generic point space (away from singularities) satisfy bound imposed tadpole cancellation condition. More precisely, while goes like 1 / 4 moduli, we amount charge induced stabilizing grows faster than this, and is therefore l...

Erythroid ferritin was isolated from tadpole red blood cells, an unusually abundant source, with an iron content of 12%. The apoprotein was characterized by sedimentation equilibrium studies, sodium dodecyl sulfate gel electrophoresis, and by determination of amino acid composition. Tadpole red cell apoferritin has a molecular weight of 478,000, a subunit size of 19,600, and an amino acid compo...

There have been contradictory reports of the relative proportion of mercury from coal-fired power plants that deposits locally. Our objective was to determine any local effect of coal-fired power plants on total mercury concentrations in wetland sediment and tadpole samples. Four power plants and 45 wetlands were selected for study. Total mercury concentrations were determined in 75 sediment sa...

Models suggest that the mechanism of competition can influence the growth advantage associated with being large (in absolute body size or relative to other individuals in the population). Large size is advantageous under interference, but disadvantageous under exploitative competition. We addressed this prediction in a laboratory experiment on Rana temporaria tadpoles competing for limited food...
