The Local Press as a Medium to Create Diversion
No full textInternational audienceThe press with the largest circulation in France—and which is virtually unknown abroad—are regional newspapers (around 50 dailies and 150 weeklies). In this chapter, Loïc Ballarini explores the content in these newspapers. Through an analysis of more than 1500 articles, he examines how the French regional press can claim (or not) to reflect the geographical area it covers. Despite the apparent diversity of news, the research shows a strict hierarchy of local information, which is voluntarily complacent about those in power and almost never critical. As if it were stuck in the consensus-based model that made it successful a century ago, the local press is unable to put its finger on long-term shifts and changes in the region. The author describes it as a diversion of attention away from social dynamics towards extremely simplified social constructs

Modelling the induction of cell death and chromosome damage by therapeutic protons
No full textA two-parameter biophysical model cal led BIANCA (BIophysical ANalysis of Cell death and chromosome Aberrations), which assumes a pivotal role for DNA cluster damage and for “lethal” chromosome aberrations, was applied to calculate cell death and chromosome aberrations for normal and radio-resistant cells along a 62-MeV eye melanoma proton beam. The yield of DNA “Cluster Lesions” and the probability for a chromosome fragment of not being rejoined with any partne r were adjustable parameters. In line with other works, the beam effectiveness at inducing both biological endpoints was found to increase with increasing depth, and high levels of damage were found also beyond the dose fall-off, due to the higher biological effectiveness of low-energy protons. This implies that assuming a constant RBE along the whole SOBP, as is currently done in clinical practice, may be sub-optimal, also implying a possible underestimation of normal tissue damage. Furthermore, the calculations suggested that for higher fractional doses, like those delivered in hypo-fractionation regimes, the relative increase in effectiven ess along the SOBP may be less pronounced than for lower fractional doses

No full textEfficient Parallel Statistical Model Checking of Biochemical Networks
No full textWe consider the problem of verifying stochastic models of biochemical networks against behavioral properties expressed in temporal logic terms. Exact probabilistic verification approaches such as, for example, CSL/PCTL model checking, are undermined by a huge computational demand which rule them out for most real case studies. Less demanding approaches, such as statistical model checking, estimate the likelihood that a property is satisfied by sampling executions out of the stochastic model. We propose a methodology for efficiently estimating the likelihood that a LTL property P holds of a stochastic model of a biochemical network. As with other statistical verification techniques, the methodology we propose uses a stochastic simulation algorithm for generating execution samples, however there are three key aspects that improve the efficiency: first, the sample generation is driven by on-the-fly verification of P which results in optimal overall simulation time. Second, the confidence interval estimation for the probability of P to hold is based on an efficient variant of the Wilson method which ensures a faster convergence. Third, the whole methodology is designed according to a parallel fashion and a prototype software tool has been implemented that performs the sampling/verification process in parallel over an HPC architecture
