On Chromaticity of Wheels
Let the vertices of a graph such that every two adjacent vertices have different color is a very common problem in the graph theory. This is known as proper coloring of graphs. The possible number of different proper colorings on a graph with a given number of colors can be represented by a function called the chromatic polynomial. Two graphs G and H are said to be chromatically equivalent, if ...
متن کاملCyclins: wheels within wheels.
Cycimns were originally defined as proteins which are synthesized in each cell cycle and destroyed at every mitosis. Cyclins were discovered by T. Hunt and students at the Marine Biological Laboratory, Woods Hole, MA, duningthe 1982 Physiology Course (1). They labeled eggs ofthe sea urchin Arbacia punctulata with [35S]methionine after fertilization and analyzed the temporal pattern of protein s...
متن کاملOptimum Path Packing on Wheels :
We show that, given a wheel with nonnegative edge lengths and pairs of terminals located on the wheel's outer cycle such that no two terminal pairs cross, then a path packing, i. e., a collection of edge disjoint paths connecting the given terminal pairs, of minimum length can be found in strongly polynomial time. Moreover, we exhibit for this case a system of linear inequalities that provides ...
متن کاملOn Wheels, Nuts and Software
In this paper I examine the issue of whether we can trust software systems and put forward an argument that in an absolute sense the answer must necessarily be no for a multitude of reasons. The paper then examines the question of whether this is an actual impediment to the successful application of software with particular reference to automotive applications. In particular I examine the quest...
متن کاملNotes on the sand fly fauna (Diptera:Psychodidae) in the State of Rio Grande do Sul, Brazil.
Proceeding with the study of taxonomy and geographical distribution of American phlebotomine sand flies, a trip was made to the Aparados da Serra National Park and to the Turvo State Park (State of Rio Grande do Sul, Brazil) between 23 January and 4 February 1986. Both parks comprise areas of primitive forest and very little is known about the phlebotomine fauna in this region. Only two reports...
