We consider a simple gravitational-heating mechanism for the long-term quenching of cooling flows and star formation in massive dark-matter haloes hosting elliptical galaxies and clusters. The virial shock heating in haloes > 10M⊙ triggers natural quenching in 10M⊙ haloes (Birnboim et al. 2007). Analytic estimates and simple simulations argue that the long-term quenching in haloes > Mmin ∼ 7×10...

in 1890, coley observed that cancer patients who developed infections had smaller tumors. from this, he developed coley’s toxin and treated tumors with injections of infectious materials. in 1960s,  mahaley used monoclonal antibodies to treat central nervous system(cns)  tumors, that research and clinical investigations in brain tumor immunotherapy became a serious undertaking. there are severa...

Hisao Mabuchi, MD, Department of Internal Medicine and Nephrology, Nishijin Hospital, Kamigyo-Ku, Kyoto 602 (Japan) Dear Sir, The accumulation of endogenous fluorescent substances in uremic sera is well documented [for example, see ref. 1], but the nature and the origin of these substances are conflicting. It is important to distinguish the nondialyzable albumin-associated fluorescent substance...

In this paper we present an Õ(m √ n log U) time algorithm for solving the maximum flow problem on directed graphs with m edges, n vertices, and capacity ratio U . This improves upon the previous fastest running time of O(mmin ( n,m ) log ( n/m ) logU) achieved over 15 years ago by Goldberg and Rao [8] and improves upon the previous best running times for solving dense directed unit capacity gra...
