Introduction Up to 80% of post-stroke patients present upper-limb motor impairment (ULMI), causing functional limitations in daily activities and loss independence. UMLI is seldom fully recovered after stroke when using conventional therapeutic approaches. Functional Electrical Stimulation Therapy (FEST) controlled by Brain–Computer Interface (BCI) an alternative that may induce neuroplastic ch...

A Gram-positive, short, rod-shaped, cream-coloured actinobacterium, designated MSL-04(T), was isolated from a soil sample collected from an agricultural field on Bigeum Island (Republic of Korea) and was subjected to polyphasic characterization to unravel its taxonomic position. The optimum growth temperature and pH were 28-30 degrees C and pH 7.2-7.4. Chemotaxonomic characteristics such as B2b...

Clonal organisms with occasional sex are important for our general understanding of the costs and benefits that maintain sexual reproduction. Cyclically parthenogenetic aphids are highly variable in their frequency of sexual reproduction. However, studies have mostly focused on free-living aphids above ground, whereas dispersal constraints and dependence on ant-tending may differentially affect...

Current approaches in schema mapping and matching focus on pair-wise comparison of schemas. This chapter gives an overview of how n-way comparison of schemas via a unified data model for large-scale multi-schema integration (ULMI) can benefit to schema matching and mapping processes. The approach integrates a set of input schemas into one comprehensive representation. Thus, a unified data model...

This report presents a survey of previous and more recent ultrastructural and cytochemical investigations of disease development in elm, caused by Ophiostoma novo-ulmi, with results of some comparative studies of other wilt diseases caused by f.spp., of Fusarium oxysporum and of Verticillium sp. For cytochemical studies, probes complexed to colloidal gold to detect cellulose, pectin, chitin, an...

Elms, especially Ulmus minor and U. americana, are carrying out a hard battle against Dutch elm disease (DED). This vascular wilt disease, caused by Ophiostoma ulmi and O. novo-ulmi, appeared in the twentieth century and killed millions of elms across North America and Europe. Elm breeding and conservation programmes have identified a reduced number of DED tolerant genotypes. In this study, thr...

Hydrophobins are components of microbial cell walls that contribute tocell surface hydrophobicity. The hydrophobic nature of the surfaces of many microbes, both prokaryotic and eukaryotic, is important to such processes as adhesion of pathogens to host structures and dispersa1 of aerial spores (Beever and Dempsey, 1978; Doyle and Rosenberg, 1990; Stringer et al., 1991). A class of peptide hydro...
