Quartet Compatibility and the Quartet Graph
A collection P of phylogenetic trees is compatible if there exists a single phylogenetic tree that displays each of the trees in P. Despite its computational difficulty, determining the compatibility of P is a fundamental task in evolutionary biology. Characterizations in terms of chordal graphs have been previously given for this problem as well as for the closely-related problems of (i) deter...
متن کاملWhat is a staph infection?
A staff infection might be when all your coworkers call in sick on the same day. But a staph (pronounced "staff") infection is an infection typically caused by staphylococcus aureus bacteria. This pesky bacterium is very common (most people have some living on their skin all the time), but when it enters the human body, usually through a break in the skin, it can cause infection anywhere in the...
متن کاملMethicillin-sensitive Staph. aureus (MSSA) and methicillin-resistant Staph. aureus (MRSA) bacteraemia decline simulaneously
Methods From April 2008 to March 2010, at Imperial College Healthcare NHS Trust (ICHNT), electronic microbiological records of patients with SAB were linked with patient administration data to determine if the S. aureus was meticillin-sensitive or resistant, and if infection was CA or HA. SAB within 2 days of admission was defined as CA, 2 days or more after admission as HA and a new episode if...
متن کاملAIDS Quartet
Not long ago, I e-mailed Donald McNeil, Jr. I wanted to know how many HIV/AIDS articles the New York Times reporter had written over the years. “Fiddling with the Times’ website and internal library . . . produces 201 to 495,” McNeil replied. “I think it’s safe to say I’ve written 400 stories about AIDS.” At the end of this piece I’ll share McNeil’s favorite, but for now I’ll state the obvious....
متن کاملShort Quartet Puzzling: A New Quartet-Based Phylogeny Reconstruction Algorithm
Quartet-based phylogeny reconstruction methods, such as Quartet Puzzling, were introduced in the hope that they might be competitive with maximum likelihood methods, without being as computationally intensive. However, despite the numerous quartet-based methods that have been developed, their performance in simulation has been disappointing. In particular, Ranwez and Gascuel, the developers of ...
