has cardinality r ≥ 1. Let G be the F-rational points of a simple Chevalley group defined over F. In his thesis, Matsumoto [5] gave a beautiful construction for the metaplectic cover G̃ of G, a central extension of G by μr(F) whose existence is intimately connected with the deep properties of the r-th order Hilbert symbol (·, ·)F : F × × F → μr(F). Metaplectic groups figure prominently in the st...

Extension of components should be consistent in the sense that the extending component does not introduce any unexpected behaviour. We formulate requirements which allow consistent extension of components in presence of explicit invariants. We concentrate on the issue of extension consistency with forwarding as the reuse mechanism, and discuss the additional problems which require solution when...

We present an explicit method to produce upper bounds for the dimension of the moduli spaces of complete integral Gorenstein curves with prescribed symmetric Weierstrass semigroups.

Cystic fibrosis (CF) is a multisystemic disease but without a classical disease-specific renal phenotype. A 32-year-old male patient with CF (ΔF508/ΔF508) presented with a nephrotic syndrome. Renal biopsy revealed nodular glomerulosclerosis (NGS) occurring in the absence of diabetes mellitus, amyloidosis and any other known common cause of NGS. He had a progressive decline in estimated glomerul...

Chemical inhibdion of dtiusion flames through addition of halogenatkd “inhibitors is a problem of significant practical and scientific interest. Extensive studies on diffusion flames in microgravity have shown that these flames have significantly different characteristics than those under normal gravity [1,2]. However, the mechanisms through which inhibitors reach the reaction zone to suppress ...

Achromobacter spp. are recognized as emerging pathogens in hospitalized as well as in cystic fibrosis (CF) patients. From 2012 to 2015, we collected 69 clinical isolates (41 patient) of Achromobacter spp. from 13 patients with CF (CF isolates, n = 32) and 28 patients receiving care for other health conditions (non-CF isolates, n = 37). Molecular epidemiology and virulence potential of isolates ...

In patients with cystic fibrosis (CF) and non-CF bronchiectasis, Pseudomonas aeruginosa is the most important respiratory pathogen. It is able to synthesise hydrogen cyanide, a potent inhibitor of cellular respiration. The present study investigated whether cyanide is present in the sputum of CF and non-CF bronchiectasis patients infected with P. aeruginosa, and whether the detection of cyanide...

stereoisograms of octahedral complexes are classified into five types (type i--typev) under the action of the corresponding rs-stereoisomeric group. their enumeration is accomplished in a type-itemized fashion, where fujita's proligand method developed originally for combinatorial enumeration under point groups (s. fujita, theor. chem. acc., 113, 73--79 (2005)) is extended to meet the requireme...
