A perfect funeral with no corpse
"Indeed, the role in mitosis of the chromosome arms, which carry most of the genetic material, may be compared with that of a corpse at a funeral: they provide the reason for the proceedings but do not take an active part in them." (Mazia, 1961)
متن کاملSensitivity of Perfect and Stone-Wales Defective BNNTs Toward NO Molecule: A DFT/M06-2X Approach
The monitoring and controlling of environmental pollutions are very important in biological and industrial processes, and a great interest is growing with the development of suitable gas–sensitive materials and hazardous chemical removal devices. In this work, the highly parameterized, empirical exchange–correlation functional M06–2X were employed to investigate the electronic sensitivity of pe...
متن کاملPerfect Graphs with No 2k 2 and No K 6
We prove that a 2K 2 minimal imperfect Berge graph (if any) contains a K 6 : A graph is perfect if the vertices of any induced subgraph H can be colored, in such a way that no two adjacent vertices receive the same color, with a number of colors (denoted by (H)) not exceeding the cardinality !(H) of a maximum clique of H. A graph is minimal imperfect if all its proper induced subgraphs are perf...
