single-stranded DNA by solving the nonlinear Poisson Boltzmann equation. The results show variations of the molecular electrostatic potential (MEP) within 3nm from the center of the sugar backbone, with suitably diﬀerentiable variations at 1.4nm distance. MEP variations among four nucleotide bases are the most signiﬁcant near ∼33.7 and

Suppose you are training using kernel regression using some unspeci ed kernel function. The only thing you know about the kernel function is that it is a monotonically decreasing function of distance that decays to zero at a distance of 3 units (and is strictly greater than zero at a distance of less than 3 units).

When there are sources S(x) of solute (for example, where solute is piped in or where the solute is generated by a chemical reaction), or of heat (e.g., an exothermic reaction), the steady-state diﬀusion is governed by Poisson s equation in the form ∇2 S(x) k.
