Journal ArticleDOI
Reduction for 3-Connected Graphs of Minimum Degree at Least Four
Sheng Bau,Akira Saito +1 more
TL;DR: It is proved that for every vertex x in a graph G, there exists either an edge e such that its contraction yields a graph in P and at least one of its endvertices is of distance at most two from x.
Journal ArticleDOI
A note on graphs contraction-critical with respect to independence number
Michael D. Plummer,Akira Saito +1 more
TL;DR: It is shown that C C R graphs can be recognized in polynomial time and defined as a class of all contraction-critical graphs with bipartite characteristics.
Journal ArticleDOI
Forbidden pairs for k-connected Hamiltonian graphs
TL;DR: For an integer k with k>=2 and a pair of connected graphs F"1 and F"2 of order at least three, the strong 2-forbidden pairs were determined by Faudree and Gould (1997) and Bedrossian (1991).
Journal ArticleDOI
On the Countint Methods of White Blood Cells in the Peripheral Blood and Nucleated Cells in the Bone Marrow, with Special Reference to Biological Significance of the Absolute Count and the Percentage of the Leucocytes
TL;DR: The distribution of body defence energy was studied from the standpoint of the hematopoietic phases of the bone-marrow and the fields and times of blood defense reaction and it was found that the cell-bacterium reaction and antibody-antigen reaction show a constant-antagonistic relation.
