New national and regional bryophyte records, 52
Marchantia paleacea is a new species for the Umbria Region and is rare in central and southern Italy.
This record is in a Site of Community Importance (SCI) IT5220017 and a Special Area of Conservation (SAC) of the Natura 2000 EU-wide network due to the presence of the 7220* ‘Petrifying springs with tufa formation (Cratoneurion)’ Annexe I priority habitat. The particular environment, with a gorge and waterfall, created a very special microclimate that allowed the establishment of interesting liverworts and mosses
Asymptotic Behavior of Nonlinear Networked Control Systems
The dening characteristic of a networked control system (NCS) is having a feedback loop that passes through a local area computer network. Our two-step design approach includes using standard control methodologies and choosing the network protocol and bandwidth in order to ensure important closed-loop properties are preserved when a computer network is inserted into the feedback loop. For su#ciently high data rates, global exponential stability is preserved. Simulations are included to demonstrate the theoretical result. KeywordsNetworked control systems, asynchronous packets. I
Città per tutti
Dal 2003, Anno Europeo delle Persone Disabili, l’inclusione delle persone con disabilità in tutti gli aspetti della vita civile, è diventata una priorità degli Stati membri. Si tratta infatti di tener conto dei bisogni di tutti nella progettazione architettonica e urbana, riuscendo ad individuare soluzioni in grado di privilegiare utenze con necessità diverse quali quella motoria, visiva, uditiva, psichica, mentale e/o cognitiva. L'accessibilità dello spazio pubblico nella città è la prima chiave verso un abitare autonomo.Since 2003, the European Year of Disabled Persons, the inclusion of persons with disabilities in all aspects of personal and civic life has become a priority for the member states. Accessibility needs to be taken into account when planning architectural and urban projects. Access to public space is the first key to indipendent living

Optimality conditions for approximate solutions of vector optimization problems
In this paper, we introduce a new kind of properly approximate efficient solution of vector optimization problems. Some properties for this new class of approximate solutions are established. Also necessary and sufficient conditions via nonlinear scalarizations are obtained for properly approximate solutions. And under the assumption of cone subconvexlike functions, we derive linear scalarizations for properly approximate efficient solutions
