A mosaic of 7 ROSAT PSPC pointed observations in the direction of (l, b ∼ 10◦, 0◦) reveals deep X-ray shadows in the 0.5 − 2.0 keV band cast by dense molecular gas. The comparison between the observed on-cloud and off-cloud X-ray fluxes indicates that ∼ 43% of the diffuse X-ray background in this direction in both the 34 keV and 1.5 keV bands originates behind the molecular gas, which is locate...

With the continued expansion of corporate information systems and the increasing use of networks, information security management (ISM) has become more important than ever. However, few empirical studies have examined the effects of firms’ internal and external factors on their ISM processes. This study investigates the role of Need Pull and Technology Push on the ISM process, and examines the ...

An atlas of the Galactic plane along with the molecular clouds in Orion, o Oph, ([4¡.7 \ b \ 4¡.7), and Taurus-Auriga, has been produced at 60 and 100 km from IRAS data. The atlas consists of resolution-enhanced co-added images with 1@È2@ resolution and co-added images at the native IRAS resolution. The IRAS Galaxy Atlas, together with the Dominion Radio Astrophysical Observatory H I line/21 cm...

OBJECTIVES The interferon (IFN) signature (IS) in patients with systemic lupus erythematosus (SLE) includes over 100 genes induced by type I IFN pathway activation. We developed a method to quantify the IS using three genes-the IS metric (ISM)-and characterised the clinical characteristics of patients with SLE with different ISM status from multiple clinical trials. METHODS Blood microarray e...

This paper uses recent gridded climatological data and a coupled general circulation model (GCM) simulation in order to assess the relationships between the interannual variability of the Indian summer monsoon (ISM) and the El Niño-Southern Oscillation (ENSO). The focus is on the dynamics of the ISMENSO relationships and the ability of the state-of-theart coupled GCM to reproduce the complex le...

We discuss the possibility of mapping interstellar clouds at unprecedentedly high spatial resolution by means of near–IR imaging of their scattered light. We calculate the scattering of the interstellar radiation field by a cloud model obtained from the simulation of a supersonic turbulent flow. Synthetic maps of scattered light are computed in the J, H and K bands and are found to allow an acc...

Dense, small molecular cloud cores have been identified as the direct progenitors of stars. One of the best studied examples is Barnard 68 which is considered a prototype stable, spherical gas core, confined by a diffuse high-pressure environment. Observations of its radial density structure however indicate that Barnard 68 should be gravitationally unstable and collapsing which appears to be i...

Wide angle Hubble Space Telescope (HST/ACS) images of the Helix Planetary Nebula (NGC 7293) are interpreted using the hydro-gravitational theory (HGT) of Gibson 1996-2000 that predicts the baryonic dark matter and interstellar medium (ISM) consist of Mars-mass primordial-fog-particle (PFP) frozen H-He planets. The new ACS images confirm and extend the O’Dell and Handron 1996 WFPC2 images showin...
