In this work, we address the codiagnosability analysis problem of a networked discrete event system under malicious attacks. The considered system is modeled by a labeled Petri net and is monitored by a series of sites, in which each site possesses its own set of sensors, without requiring communication among sites or to any coordinators. A net is said to be codiagnosable with respect to a fault if at least one site could deduce the occurrence of this fault within finite steps. In this context, we focus on a type of malicious attack that is called stealthy intermittent replacement attack. The stealthiness demands that the corrupted observations should be consistent with the system's normal behavior, while the intermittent replacement setting entails that the replaced transition labels must be recovered within a bounded of consecutive corrupted observations(called as K-corruption intermittent attack). Particularly, there exists a coordination between attackers that are separately effected on different sites, which holds the same corrupted observation for each common transition under attacks. From an attacker viewpoint, this work aims to design Kcorruption intermittent attacks for violating the codiagnosability of systems. For this purpose, we propose an attack automaton to analyze K-corruption intermittent attack for each site, and build a new structure called complete attack graph that is used to analyze all the potential attacked paths. Finally, an algorithm is inferred to obtain the K-corruption intermittent attacks, and examples are given to show the proposed attack strategy.

1. Introduction The tegmental wall of the tympanic cavity is a thin plate of the temporal bone that separates the middle cranial fossa(MCF) from the ear. This anatomical region consists of two areas: an anterior one, comprised of the tegmen tympani(To′th et al., 2007), and a posterior one, formed by the tegmen antri and the tegmen mastoideum(Makki et al., 2011). In some patients, the tegmental region of the temporal bone can be interrupted, causing a tegmen defect(TD). A TD is sometimes associated with a meningoencephalic herniation(MEH), in which brain tissue herniates through a TD.

Tissue or organ regeneration is a complex process with successful outcomes depending on the type of tissue and organism. Upon damage, mammals can only efficiently restore a few tissues including the liver, skin, epithelia of the lung, kidney, and gut. In contrast, lower vertebrates such as zebrafish possess an extraordinary regeneration ability, which restores the normal function of a broad spectrum of tissues including heart, fin, brain, spinal cord, and retina. This regeneration process is either mediated by the proliferation of resident stem cells, or cells that dedifferentiate into a stem cell-like. In recent years, evidence has suggested that the innate immune system can modulate stem cell activity to initiate the regenerative response to damage. This review will explore some of the newer concepts of inflammation in zebrafish regeneration in different tissues. Understanding how inflammation regulates regeneration in zebrafish would provide important clues to improve the therapeutic strategies for repairing injured mammalian tissues that do not have an inherent regenerative capacity.

Objectives: To evaluate the primary lesions, the complications and the evolution of disease in patients affected by H1N1 viral infection. Materials and Methods: 24 Patients affected by H1N1 infection, diagnosed by polymerase chain reaction (PCR) on throat swabs, underwent CT examination. Seven patients were hospitalized in intensive care unit (ICU). In five patients the evolution of disease was monitored. The following features were evaluated: primary lesions significant for viral infection, their possible complications and the evolution of disease in controlled patients. Results: Primary lesions variously associated with each other were found in 22 out of 24 patients: ground glass opacities (19/24, 79.2%), interstitial thickening (13/24, 54.2%), centrilobular nodules (3/24, 12.5%) and consolidation (8/24, 33.3%). The following complications were observed: 3 consolidations with air bronchogram, 9 pleural effusions, 7 ARDS and 1 barotrauma. In the 5 patients who underwent follow-up (including 3 admitted to ICU), complete resolution was demonstrated in 4 cases and focal fibrotic evolution in one case. 3 ICU patients affected by ARDS died. Conclusions: In case of H1N1 virus infection. CT is an important tool for staging the disease, recognize complications and to study disease

Myelofibrosis (MF) represents the major long-term complication of essential thrombocythemia (ET). There is evidence that leukocytosis at diagnosis is associated with poorer survival in patients with ET. In this study, we retrospectively evaluated 143 patients with ET, diagnosed in agreement with WHO criteria, followed in a single centre over >10 years. Nine of them transformed into MF (post-essential thrombocythemia-myelofibrosis PET-MF). We compared PET-MF data at diagnosis with that of the remaining 134 patients (ET-1) and with a selected sub-group of ET-1 (ET-2, 19 pats) sex, age and follow-up duration matched to PET-MF. The PET-MF evolution rate was 4.6 per 1000 person-years;white blood cells count (WBC) count, haemoglobin levels and hematocrit were higher in PET-MF than in ET-1 (P = 0.01) while only WBC was higher than in ET-2 (P = 0.01). With multivariate analysis, only WBC count retained its signifi-cance. Our study highlights the prognostic relevance of leukocytosis on myelofibrotic transformation of ET.
