The Northern Cross radiotelescope in Medicina is being used by the Basic Element for SKA Training project (BEST, Montebugnoli et al. 2006) as test bed for technological developments aimed at the Square Kilometer Array (SKA),within the SKA-Design Studies (SKA-DS) programme. In the framework of these activities, 6 of the 24 East-West arm sections of the original telescope will be refurbished, alo...

Nucleotide sequences of Rubisco Large Subunit (rbcL) and the internal transcribed spacers (ITS) of nrDNA were obtained for the five species of Larrea and one species each of Bulnesia (ITS only) and Plectrocarpa (rbcL only). Parsimony analyses were conducted, including sequences from seven genera of Zygophyllaceae reported by other authors-Kallstroemia, Zygophyllum, Augea, Fagonia, Pintoa, Guaia...

The closed-loop product lifecycle management (PLM) system focuses on tracking and managing the information of the whole product lifecycle, with possible feedback of information to product lifecycle phases. It provides opportunities to reduce the inefficiency of lifecycle operations and gain competitiveness. Thanks to the advent of hardware and software related to product identification technolo...

Based on molecular and morphological data we investigated the taxonomy and phylogeny of the ectomycorrhizal genus Tricholoma in northern Europe. Our phylogenetic tree confirmed the presence of at least 72 well circumscribed species within the region. Of these, three species, viz. T. boreosulphurescens, T. bryogenum and T. ilkkae are described as new to science, based on morphological, distribut...

gramineis foliis capitulis parvis." Linnaeus (1759) published alter­ nate names for Sloane's plant under both Peetis and Verbesina. The history of sect. longc Pectidium is closely intertwined with a ­ standing misapplication of the name Pectis linifolia. Only a year after Linnaeus described P. linifolia, {f . Jacquin (1760) published Pectis punctata. P. now to be tax-­ e ll Although punctata is...

Quantum error-correcting codes have attracted much attention. Among many research articles, the most general and systematic construction is the so called stabilizer code construction [6] or additive code construction [2], which constructs a quantum error-correcting code as an eigenspace of an Abelian subgroup S of the error group. Thereafter Calderbank et al. [3] proposed a construction of S fr...

This article is devoted to the most recent, i.e. taking place within the last few years, theoretical developments in the field of intermolecular interactions. The most important advancement during this time period was the creation of a new version of symmetry-adapted perturbation theory (SAPT) which is based on the density-functional theory (DFT) description of monomers. This method, which will...

In this study, we expanded Acer sect. Rubra Pax to include A. sect. Hyptiocarpa Fang. Traditionally, section Rubra comprises two iconic species, Acer rubrum Linnaeus (red maple) and A. saccharinum Linnaeus (silver maple), of eastern North American forests as well as the rare Japanese montane species, A. pycnanthum K. Koch. Section Hyptiocarpa consists of A. laurinum Hasskarl and A. pinnatinervi...
