The semi-aquatic pondweed bugs of a Cretaceous swamp
Pondweed bugs (Hemiptera: Mesoveliidae), considered a sister group to all other Gerromorpha, are exceedingly rare as fossils. Therefore, each new discovery of a fossil mesoveliid is of high interest, giving new insight into their early evolutionary history and diversity and enabling the testing of their proposed relationships. Here, we report the discovery of new mesoveliid material from Spanis...
متن کاملEffects of Turbidity on Fluridone Treatments for Curlyleaf Pondweed Control
PURPOSE: A small-scale study was conducted to evaluate fluridone (1-methyl-3-phenyl-5-[3trifluoromethyl)phenyl]-4(1H)-pyridinone) efficacy under varying levels of turbidity when controlling curlyleaf pondweed (Potamogeton crispus L.). There is no information on the effect of turbidity on fluridone efficacy against curlyleaf pondweed. It is unknown if turbidity impacts aqueous fluridone concentr...
متن کاملFrancis Richardson Cross
sometimes referred with very natural pride. It was in 1878 that he was invited to come to University College, Bristol, as Lecturer in Anatomy, and in the same year he was appointed Assistant Surgeon to the Bristol Royal Infirmary. A year later he became full surgeon, and in 1880 he was appointed Dean of the Faculty of Medicine at University College. Thus, to use his own expression, he had not b...
متن کاملLittlewood–Richardson polynomials
We introduce a family of rings of symmetric functions depending on an infinite sequence of parameters. A distinguished basis of such a ring is comprised by analogues of the Schur functions. The corresponding structure coefficients are polynomials in the parameters which we call the Littlewood–Richardson polynomials. We give a combinatorial rule for their calculation by modifying an earlier resu...
متن کاملSmall Littlewood-Richardson coefficients
We develop structural insights into the Littlewood-Richardson graph, whose number of vertices equals the Littlewood-Richardson coefficient cνλ,μ for given partitions λ, μ and ν. This graph was first introduced in [BI12], where its connectedness was proved. Our insights are useful for the design of algorithms for computing the Littlewood-Richardson coefficient: We design an algorithm for the exa...
