How to make a graph bipartite

Let G be a graph with vertex set V(G) and edge set E(G), respectively. The set of vertices adjacent to an x e V(G) is denoted by F(x), and the degree of x is d(x) = I F(x)l . For any subset V 'g V(G), let G[ V] denote the subgraph of G induced by the vertices of V' . Further, let K n stand for the complete graph on n vertices. It is easily seen (e.g ., Erdös [7]) that every graph G with n verti...

How many random edges make a dense graph hamiltonian?

This paper investigates the number of random edges required to add to an arbitrary dense graph in order to make the resulting graph hamiltonian with high probability. Adding (n) random edges is both necessary and sufficient to ensure this for all such dense graphs. If, however, the original graph contains no large independent set, then many fewer random edges are required. We prove a similar re...

How to make a helix

lant stems twist and turn with the help of aberrant microtubule structures, according to results from Siripong Thitamadee, Kazuko Tuchihara, and Takashi Hashimoto (Nara Institute of Science and Technology, Ikoma, Japan). The insights come from studies of Arabidopsis thaliana , which normally grows straight. Hashimoto’s team isolated lefty1 and lefty2 —which have left-handed helical growth—as su...

How to make a lysosome

How to make a lysosome oated vesicles had been described as early as 1961. These small membranous structures were characterized by a highly organized layer of material on the cytoplasmic surface, “but no one knew their function,” says Marilyn Farquhar, whose lab at the time had become interested in how the Golgi complex helped produce enzymes. Roth and Porter (1964) had provided evidence that c...

How to make a magnetosphere

originates from the Sun and expands radially into the interplanetary space. As it encounters the various bodies in the solar system it creates a variety of disturbances depending on the effective size of the obstacle. Two measures are important: the gyroradius, ρi, is the radius of the particle orbit around the magnetic field (B) due to the Lorentz force, and is given by ρ= vth /Ω= vthm / qB, w...
