Pasteur's quadrant is a classification of scientific research projects that seek fundamental understanding of scientific problems, while also having immediate use for society. Louis Pasteur 's research is thought to exemplify this type of method, which bridges the gap between " basic " and " applied " research. [ 1 ]
The eukaryotic cell cycle is very complex and is one of the most studied topics, since its misregulation leads to cancers. It is possibly a good example of a mathematical model as it deals with simple calculus but gives valid results. Two research groups [1] [2] have produced several models of the cell cycle simulating several organisms. They ...
Point quadtrees are constructed as follows. Given the next point to insert, we find the cell in which it lies and add it to the tree. The new point is added such that the cell that contains it is divided into quadrants by the vertical and horizontal lines that run through the point. Consequently, cells are rectangular but not necessarily square.

The repair model, instead of the target theory, emphasizes how a cell utilizes said cell’s repair mechanisms up to the limit of the cell’s repair machinery (the end of the shoulder). After the limit of the cell’s machinery is reached, the repair model generally notes that if any damage is left unhealed the dying process will be initiated.
Explicitly, we get that the graph with zero edges has probability , every graph with exactly one edge has probability , every graph with exactly two edges has probability , and the graph with exactly three edges has probability in this example. Intuitively, the structure of graph probabilities in this ERGM example are consistent with typical ...
In network science, the Configuration Model is a family of random graph models designed to generate networks from a given degree sequence. Unlike simpler models such as the Erdős–Rényi model , Configuration Models preserve the degree of each vertex as a pre-defined property.
Cell cycle analysis by DNA content measurement is a method that most frequently employs flow cytometry to distinguish cells in different phases of the cell cycle.Before analysis, the cells are usually permeabilised and treated with a fluorescent dye that stains DNA quantitatively, such as propidium iodide (PI) or 4,6-diamidino-2-phenylindole (DAPI).
