The domatic partition problem seeks to maximize the partitioning of the nodes of the network into disjoint dominating sets. These sets represent a series of virtual backbones for wireless sensor networks to be activated successively, resulting in more balanced energy consumption and increased network robustness. In this study, we address the domatic partition problem in random geometric graphs ...

In the fractional graph colouring problem, the task is to schedule the activities of the nodes so that each node is active for 1 time unit in total, and at each point of time the set of active nodes forms an independent set. We show that for any α > 1 there exists a deterministic distributed algorithm that finds a fractional graph colouring of length at most α(∆ + 1) in any graph in one synchro...

The present study investigates whether phonetic lessons enable improvement of adult L2 perception and whether 2) L2 perceptual learning in the classroom setting can be explained by the Second Language Linguistic Perception (L2LP) model (Escudero, 2005). Salento Italian (SI) listeners' initial state of perception of American English (AE) vowels was examined. SI listeners performed cross‐ languag...

The number of sensilla campaniformia and sensilla coeloconica + sensilla ampullacea of flagellomeres 2 to 11 of the antennae of three types of males (Italian, African and Africanized) was determined by scanning electron microscopy. Comparison of the three male types showed that Italian males did not differ from African males in number of sensilla coeloconica + sensilla ampullacea and that both ...

In 2015 an ample and challenging discussion regarding professional associations is under way in Italy. Professional associations are self-government institutions that control and monitor the correctness and quality of the activities of the professionals registered in professional records recognized by the law. Professional associations have to prepare and update both their official registers an...

The generic-level taxa included in Pterostichini and Loxandrini from New Caledonia are reviewed and a key to genera and species provided. Two new genera are described, Paniestichus and Abacophrastus, with the following new species: Paniestichus subsolianus, Abacophrastus millei, Abacophrastus chapes, Abacophrastus carnifex, Abacophrastus hobbit, Abacophrastus megalops, Abacophrastus reflexus an...
