251   Pulsar timing for the Fermi gamma-ray space telescope Pulsar timing for the Fermi gamma-ray space telescope    2008 We describe a comprehensive pulsar monitoring campaign for the Large Area Telescope (LAT) on the Fermi Gamma-ray Space Telescope (formerly GLAST). The detection and study of pulsars in gamma rays give insights into the populations of neutron stars and supernova rates in the Galaxy, into particle acceleration mechanisms in neutron star magnetospheres, and into the "engines" driving pulsar wind nebulae. LAT's unprecedented sensitivity between 20 MeV and 300 GeV together with its 2.4 sr field-of-vi... 查看全文

252   Facile Exchange of Ligands on the 6-Mercaptopurine-Monolayer Protected Gold Clusters Surface† Facile Exchange of Ligands on the 6-Mercaptopurine-Monolayer Protected Gold Clusters Surface† Encarnación Reyes, Rafael Madueño, Manuel Blázquez, and Teresa Pineda*    2010 We have investigated the exchange of 6-mercaptopurine (6MP) molecules by 11-mercaptoundecanoic acid (MUA) and 11-mercapto-1-undecanol (MUOH) on the surface of monolayer protected gold clusters (6MP-MPCs) of 2.4 nm diameter. After the addition of MUA or MUOH to the 6MP-MPC solutions the absorption band at 312 nm due to 6MP is suddenly observed. The monitoring of this signal allows us the study of the place-exchange reactions. The final products obtained from the exchange at different molecular ra... 查看全文

253   The hottest white dwarfs in the Local Group The hottest white dwarfs in the Local Group    2006 The nature of the progenitor stars of supernovae of type la, the "standard candles" on which much of what we know on the dynamics and geometry of the Universe is based, is still a matter of debate. Close binary supersoft X-ray sources (CBSS) are among likely progenitors: they are often observed, yet are still-elusive for many observational and technical difficulties involved. Our own galactic backyard, the Local Group, is ideal to study these stars, because of to the low column density of neutra... 查看全文

255   X-ray emission line gas in the LINER galaxy M 81 X-ray emission line gas in the LINER galaxy M 81    2003 We present the soft X-ray spectrum of the LINER galaxy M 81 derived from a long observation with the XMM-Newton RGS. The spectrum is dominated by continuum emission from the active nucleus, but also contains emission lines from Fe L, and H-like and He-like N, O, and Ne. The emission lines are significantly broader than the RGS point-source spectral resolution; in the cross dispersion direction the emission lines are detected adjacent to, as well as coincident with, the active nucleus. This impli... 查看全文

Buchmueller, Anthony T. Lo Sasso, Ithai Lurie and Sarah Dolfin    2008 Five patients with either “diencephalic” or “brainstem” epilepsy or “diencephalosis” were examined EEGcally during the course of their hospitalization. The significant changes were detected, mainly by diphenhydramine activation as to the distribution of the 6–14/sec positive spike pattern on the scalp.

262   Abstract IS CYBER RESILIENCE IN MEDICAL PRACTICE SECURITY ACHIEVABLE? Abstract IS CYBER RESILIENCE IN MEDICAL PRACTICE SECURITY ACHIEVABLE? Patricia A. H. Williams    0 Australia is moving to a national e-health system with a high level of interconnectedness. The scenario for recovery of such a system, particularly once it is heavily relied upon, may be complex. Primary care medical practices are a fundamental part of the new e-health environment yet function as separate business entities within Australia’s healthcare system. Individually this means that recovery would be reliant on the selfsufficiency of each medical practice. However, the ability of these pra 查看全文

The density of the ambient medium where the supernova remnant evolves is a relevant parameter for its hydrodynamical evolution, for the mechanism of particle acceleration, and for the emission at TeV energies. Aims. Using XMM-Newton X-ray observations, we present a study of the ambient medium density of the historical supernova remnant SN 1006. Methods. We modelled the post-shock thermal emission to constrain the ambient medium density. Our study is focused on the North-west and the Sou... 查看全文

270   Conclusions from a dynamic population model for tsetse: response to comments Conclusions from a dynamic population model for tsetse: response to comments Hugh J. Barclay;Marc J. B. Vreysen    2011 The critique by Hargrove et al. (Popul Ecol, 2011) of our recently published paper on a tsetse population model (Barclay and Vreysen in Popul Ecol 53:89–110, 2011) has made some good points but has also misinterpreted the intent of some of our results as we presented them. Hargrove et al. rightly say that there is a mismatch between the size of the unit cells in the model (1 ha) and the iteration rate of the model (every 5 days), yielding too low a dispersal... 查看全文

274   X-ray line emission from supernova ejecta fragments X-ray line emission from supernova ejecta fragments    2002 We show that fast moving isolated fragments of a supernova ejecta composed of heavy elements should be sources of Kα X-ray line emission of the SN nuclear-processed products. Supersonic motion of the knots in the intercloud medium will result in a bow-shock/knot-shock structure creation. Fast nonthermal particles accelerated by Fermi mechanism in the MHD collisionless shocks diffuse through a cold metallic knot, suffering from Coulomb losses and producing the X-ray emission. We modeled the... 查看全文

277   X-ray synchrotron emission from supernova remnants X-ray synchrotron emission from supernova remnants    2006 X-ray synchrotron emission tells us of the highest energy reached by accelerated electrons. In a few supernova remnants (SN 1006, G347.3-0.5) this is the dominant form. of X-ray radiation, but in most it is superposed to the dominant thermal emission. Thanks to the spectro-imaging capability of Chandra and XMM-Newton, X-ray synchrotron emission has now been unambiguously detected in most young supernova remnants (Cas A, Tycho, Kepler). It arises in a very thin shell (a few arcsecs) at the blast ... 查看全文

Recent developments in the study of mixed morphology supernova remnants (MMSNRs) have revealed the presence of metal-rich X-ray emitting plasma inside a fraction of these remnants, a feature not properly addressed by traditional models for these objects.Aims. Radial profiles of thermodynamical and chemical parameters are needed for a fruitful comparison of data and model of MMSNRs, but these are available only in a few cases.Methods. We analyzed XMM-Newton data of two MMSNRs, namely IC ... 查看全文
