Cortical biopsies of 13 patients with clinical diagnosis of congenital hydrocephalus, Arnold-Chiari malformation and hydrocephalus, and postmeningitis hydrocephalus were examined by transmission electron microscopy to study the damage of endothelial cells, basement membrane, astrocytic end-feet layer, and perivascular space. Capillaries from the parietal and frontal cortex showed increased vesi...

we show that the category of convergence approach spaces is a simultaneously reective and coreective subcategory of the category of latticevalued limit spaces. further we study the preservation of diagonal conditions, which characterize approach spaces. it is shown that the category of preapproach spaces is a simultaneously reective and coreective subcategory of the category of lattice-valued p...

urbanisation is still one of the social themes in developing countries. in china, the rapid process of urbanisation and economic growth bring to people not only more opportunities for creating new life and pursuing happiness, but also the challenge to face various and complex social, economical and environmental problems. among them some are outstanding, like the shrinking plowland devoured by ...

Durchgängige, automatisierte Prozesse können Prozesskosten um 30 bis 40 Prozent senken und Durchlaufzeiten signifikant verkürzen. Der vorliegende Beitrag zeigt anhand eines siebenstufigen Vorgehens, wie umgesetzt werden. Dazu werden die Stufen (wie Aufnahme, Optimierung, Automatisierung Monitoring) inklusive möglicher Methoden Technologien dargestellt. Neben Robotic Process Automation (RPA) kom...

The front end visual system belongs to the best studied brain areas. Scale-space theory, as pioneered by Iijima in Japan [11, 41, 43] and Koenderink [12] has been heavily inspired by the important derivation of the Gaussian kernel and its derivatives as regularized differential operators, and the linear diffusion equation as its generating PDE. The view visual system as a ’geometry’ engine is t...
