Cation intermixing at the n-type polar LaGaO3/SrTiO3 (001) interface is investigated by first principles calculations. Ti⇔Ga, Sr⇔La, and SrTi⇔LaGa intermixing are studied in comparison to each other, with a focus on the interface stability. We demonstrate in which cases intermixing is energetically favorable as compared to a clean interface. A depopulation of the Ti 3dxy orbitals under cation i...

High-level synthesis consists of many interdependent tasks such as scheduling, allocation and binding. All tasks in high-level synthesis are NP-complete and the design objectives are in conflict for nature, most of the already proposed approaches are not efficient in the exploration of the design space and not effective in the identification of different trade-offs. For these reasons, genetic a...

The occurrence of Alyssum desertorum, a species belonging to A. sect. Alyssum, is reported for the fi rst time in Italy. It was found in Abruzzo (central Italy) in the territory of National Park of Gran Sasso and Laga mountains and surrounding areas. Morphological similarities with the other taxa recorded in Italy belonging to A. sect. Alyssum are briefl y discussed. Information about the typif...
