A survey for gamma-ray emission from OB associations with INTEGRAL: some preliminary results

Recent studies indicated that there might be a correlation between OB associations and unidentified gamma-ray sources from the 3EG catalogue. Moreover, when extrapolating the fluxes measured by EGRET at energies higher than 100 MeV with a power-law down to the energy range of ISGRI, the expected count rates should be large enough to be detected with INTEGRAL. As most of these OB associations are located within the Galactic plane, they are being observed by INTEGRAL as part of the Core Program (CP) during both the Galactic Plane Scans (GPS) and the Galactic Center Deep Exposure (GCDE). Combining public and CP data, we have performed a survey for gamma-ray emission from OB associations and the first results are presented in this paper. [less ▲]

The purpose of the study was to investigate the prevalence of gastric lesions and to provide diagnostic values for serum pepsinogen in non-infected pigs and in pigs with gastric disease. In an abattoir survey, the pepsinogen concentrations were measured in the serum from 62 non-infected pigs, 33 pigs with gastric lesions and 17 pigs infected with Hyostrongylus rubidus, using a specific radioimmunoassay (RIA). The mean (+/-SE) pepsinogen concentrations in the serum of non-infected pigs, in pigs with gastric ulcers, and in pigs with a heavy H. rubidus infection were 630.8 +/- 39.2 ng/ml, 1084.5 +/- 166.2 ng/ml and 1095.2 +/- 102.3 ng/ml, respectively (p < 0.05). Because of the higher concentrations of pepsinogen in the blood of pigs with gastric ulcers or parasitic infections, it is suggested that the measurement of serum pepsinogen by RIA may be an effective biochemical approach to the diagnosis of chronic gastric disorders in pigs.

In the last few years, there has been a large body of literature on congestion control based on optimization and control theories. This paper provides an overview of optimization flow control starting from the first original papers, and traces the development in a unified framework, from unicast to multicast, from theory to algorithms to implementation issues. The optimal congestion control problem is formulated, both for unicast and multicast. Decentralized theoretical solutions are derived by applying duality theory. Based on these results, actual generic algorithms and implementations are proposed for solving these problems in a distributed way. Some alternative methods not based on duality theory are also reviewed. Finally the complementary problem of choosing suitable utility functions in the optimization problem is addressed.
