In the words of D D Jackson, the data of real-world inverse problems tend to be inaccurate, insufficient and inconsistent (1972 Geophys. J. R. Astron. Soc. 28 97–110). In view of these features, the characterization of solution uncertainty is an essential aspect of the study of inverse problems. The development of computational technology, in particular of multiscale and adaptive methods and ro...

Sensor array imaging arises in applications such as nondestructive evaluation of materials with ultrasonic waves, seismic exploration, and radar. The sensors probe a medium with signals and record the resulting echoes, which are then processed to determine the location and reflectivity of remote reflectors. These could be defects in materials such as voids, fault lines or salt bodies in the ear...

S 73 comprehensive phylogeny for Arachis is lacking. Sequence information from plastid trnT-trnF and nuclear ITS from a total of 47 species representing all nine sections have been used to reconstruct the first molecular phylogeny for the entire genus, with Chapmannia and Stylosanthes as outgroup. Our results from ITS sequences show that the allotetraploid species A. hypogaea and A. monticola c...

Objective: We aimed to evaluate the inactivation of COX-2 , HMLH1 and CDKN2A by promoter methylation and its relationship with the infection by different Helicobacter pylori strains in gastric cancer. Methods: DNA extracted from 76 H. pylori -positive gastric tumor samples was available for promoter methylation identification by methylation-specific PCR and H. pylori subtyping by PCR. Immunohis...

Alcoholic hepatitis is an acute manifestation of alcoholic liver disease with mortality as high as 40-50% in severe cases. Patients usually have a history of prolonged alcohol abuse with or without a known history of liver disease. Although there is significant range in severity at presentation, patients with severe alcoholic hepatitis typically present with anorexia, fatigue, fever, jaundice, ...

I first summarize Baltag and Smets’ contribution to this volume, and praise their work. Then I compare the anti-lexicographic plausibility update that they propose to a proposal by Aucher, as an illustration of the difference between a qualitative and a quantitive formulation of updates. I quote Spohn’s original work that is at the root of research in plausibility updates and of the notion of a...

We examine the effects of weekend versus weekday and work versus nonwork experiences on mood and other well-being indicators in a sample of 74 men and women employed in a wide variety of occupations. It was hypothesized that both weekends and nonworking times would be associated with enhanced well-being, and that these relations would be mediated by greater satisfaction of autonomy and relatedn...
