متن کاملReticulation in Evolution
Molecular phylogenetics, the study of reconstructing evolutionary trees, is a well-established field of scientific endeavor. However, in certain circumstances evolution is not completely tree-like. For example, a comparison of gene trees representing a set of present-day species and reconstructed for different genetic loci often reveals conflicting tree topologies. These discrepancies are not a...
متن کاملReticulation-Visible Networks
Let X be a finite set, N be a reticulation-visible network on X, and T be a rooted binary phylogenetic tree. We show that there is a polynomial-time algorithm for deciding whether or not N displays T . Furthermore, for all |X| ≥ 1, we show that N has at most 8|X| − 7 vertices in total and at most 3|X| − 3 reticulation vertices, and that these upper bounds are sharp.
متن کاملHypernephroma and Spindle-cell Sarcoma of the Kidney
There has been continued interest in the nature of tumours arising in the kidney and suprarenal glands since Grawitz in 1883 described renal tumours arising from suprarenal rests, which he called hypernephroma. Others have described tumours varying from the hypernephroma type in cell structure, while yet maintaining in part the character of the true Grawitz tumour. The case which is presented h...
