We report the discovery of the galaxy cluster ClJ1226.9+3332 in the Wide Angle ROSAT Pointed Survey (WARPS). At z = 0.888 and LX = 1.1× 10 45 h 50 erg s −1 (0.5− 2.0 keV) ClJ1226.9+3332 is the most distant X-ray luminous cluster currently known. The mere existence of this system represents a huge problem for Ω0 = 1 world models. At the modest (off-axis) resolution of the ROSAT PSPC observation ...

This study investigated the prevalence of oral soft tissue lesions in children infected with HIV and the relationship of CD4 lymphocyte levels with the prevalence of those lesions. Sixty HIV-positive children enrolled in the Children's Hospital AIDS Program (age 5.8 +/- 3 years) were selected for study. Only five subjects (8%) had healthy gingiva and a low mean plaque index (22%). The remainder...

The discovery of alleles that are able to distort segregation during meiosis in their favour raises the question of why Mendelian segregation is the rule and segregation distortion the exception. Previous research on this topic was limited by an unrealistic assumption: equal segregation in the two sexes. Ubeda and Haig [(2005) Genetics 170, 1345-1357] provide a new model allowing sex-specific s...

This paper describes a new methodology for automatic location of the optic disc in retinal images, based on the combination of information taken from the blood vessel network with intensity data. The distribution of vessel orientations around an image point is quantified using the new concept of entropy of vascular directions. The robustness of the method for OD localization is improved by cons...
