We re-analyzed X-ray data collected with the ROSAT and ASCA observatories on a candidate neutron star (NS) near the center of the supernova remnant PKS 1209–52. We fitted the observed spectra with NS atmosphere models. The hydrogen atmosphere fits yield more realistic parameters of the NS and the intervening hydrogen column than the traditional blackbody fit. In particular, for a NS of mass 1.4...

We report on our search for the optical/infrared counterparts to the central compact objects in four young supernova remnants: Pup A, PKS 1209−52, RCW 103, and Cas A. The X-ray point sources in these supernova remnants are excellent targets for probing the existence of supernova fallback disks, since irradiation of a disk by a central X-ray source should lead to an infrared excess. We used grou...

A~trac t -A recursive, nonparametric method is developed for performing density estimation derived from mixture models, kernel estimation and stochastic approximation. The asymptotic performance of the method, dubbed "adaptive mixtures" (Priebe and Marchette, Pattern Recognition 24, 1197-1209 (1991)) for its data-driven development of a mixture model approximation to the true density, is invest...

Acute aphasia is rare in multiple sclerosis. We describe 3 patients with multiple sclerosis who had acute exacerbations presenting as aphasias. One patient had a mixed transcortical aphasia, 1 had a transcortical motor aphasia, and 1 had a Broca aphasia. Magnetic resonance imaging scans of the brain with contrast enhancement revealed new white matter lesions in the left hemisphere in all 3 pati...

2014 The diamagnetic susceptibilities of some 4,4’-disubstituted biphenyl cyclohexanes are reported as a function of temperature. The order parameters of the uniaxial nematic, smectic A and smectic B phases are calculated. The effect of the terminal substituents and the central groups on the magnetic anisotropy and the order parameter is discussed. J. Physique 44 (1983) 1209-1213 OCTOBRE 1983, ...
