the k-nearest neighbors of v i. However, this definition leads to a directed graph, as the neighborhood relationship is not symmetric. There are two ways of making this graph undirected. The first way is to simply ignore the directions of the edges, that is we connect v i and v j with an undirected edge if v i is among the k-nearest neighbors ...

Hydrogen Bonds - Brandeis
www.bio.brandeis.eduknow this interaction falls off with 1/r3 so the interaction will only matter between nearest neighbors. This dipole-dipole interaction provides much of the source for a hydrogen bond’s energy. Lets see how much energy this type of interaction is worth. For example in a helix the dipole along the peptide bond is roughly +0.4-0.4.
