"La novela picaresca entre realismo y representacion de la realidad: El caso del Buscon"
No full textEl autor investiga sobre el concepto de realismo a través de las páginas del Buscón. Se discute sobre el tópico de la literatura realista española y su relación con un estilo literario que triunfa en la segunda mitad del siglo XIX. Para Antonio Gargano hay que tener en cuenta la distancia cómica que el lector está obligado a tomar cuando lee la novela picaresca. The author analyses the concept of Realism throughout the pages of the Buscón by Quevedo. Mainly, he tries to discuss on the well-known topic of Spanish realistic literature and its relations with the literary style of the second half of the XIXth Century. The clue to understand the difference is the funniness of the picaresque novel

Fault-tolerant minimum broadcast networks
No full textAhlswede R, Gargano L, Haroutunian HS, Khachatrian LH. Fault-tolerant minimum broadcast networks. NETWORKS. 1996;27(4):293-307.Broadcasting is the task of transmitting a message originated at one processor of a communication network to all other processors in the network. A minimal k-fault-tolerant broadcast network is a communication network on n vertices in which any processor can broadcast in spite of up to k line failures in optimal time T-n(k). In this paper, we study B-k(n), the minimum number of communication lines of any minimal k-fault-tolerant broadcast network on n processors. We give the value of B-k(n) for several values of n and k and, in case k < [log n], give almost-minimum k-fault-tolerant broadcast networks. (C) 1996 John Wiley & Sons, Inc

Immunization in the Threshold Model: A Parameterized Complexity Study
No full textWe consider the problem of keeping under control the spread of harmful items in networks, such as the contagion proliferation of diseases or the diffusion of fake news. We assume the linear threshold model of diffusion where each node has a threshold that measures the node’s resistance to the contagion. We study the parameterized complexity of the problem: Given a network, a set of initially contaminated nodes, and two integers k and l, is it possible to limit the diffusion to at most k other nodes of the network by immunizing at most l nodes? We consider several parameters associated with the input, including the bounds k and l, the maximum node degree Δ , the number ζ of initially contaminated nodes, the treewidth, and the neighborhood diversity of the network. We first give W[1] or W[2]-hardness results for each of the considered parameters. Then we give fixed-parameter algorithms for some parameter combinations

And 'this is an opportunity to see what has changed in the territorial and socio-economic features of this particular territory, from 2003 at the research done with Viesti
Comparing flower biology in five species of Gagea (Liliaceae) from southern Italy
Get PDFThe reproductive traits in Gagea are affected by both abiotic and biotic environmental factors. However, further intrinsic drivers, like the ploidy level, could also have a significant influence on the sexual efficiency of these geophytes. Here, we present a comparative study involving the reproductive biology of five species of Gagea occurring in southern Italy, and representing different ploidy levels. The experimental investigations included flower phenology, pollen quality (i.e., morphology, viability, and germination), and stigma receptivity. Such data were then combined with information on seed-set available from previous work. All the studied species showed a gradual pollen presentation, and an early and durable stigma receptivity. Such traits represent effective functional adaptations to prevent pollen limitation under the unpredictable weather dynamics typical of the early blooming season of these plants. The use of a diluted substrate favoured the rate of pollen germination in vitro and, likely, it represents a further adaptation versus adverse environmental conditions (i.e., rain damage on exposed pollen). However, the rates of pollen viability and germination were generally low and appeared related to the ploidy level. Data inherent pollen quality (i.e. morphology, viability and germination) and seed-set indicated the hexaploid G. lutea as the most fertile species, while the heptaploid G. fragifera had the lowest scores for all the considered traits. Finally, by considering the isolation and reduced size of the studied population, the unexpected low fertility found in the diploid G. minima was possibly due to inbreeding depression related to the relict status of this species in southern Italy
