The distribution of the Southern Ocean (SO) biota is the result of the separation between Antarctic Peninsula and southern South America around 32 million years ago (Ma). Several groups of organisms exhibit marked taxonomic similarities between these cont

This paper is devoted to the study of positive radial solutions of the scalar curvature equation, i.e. !u(x) +K(|x|)uσ−1(x) = 0 where σ = 2n n−2 and we assume that K(|x|) = k(|x|ε) and k(r) ∈ C1 is bounded and ε >0 is small. It is known that we have at least a ground state with fast decay for eac...

We present a forecasting strategy based on stationary wavelet transform combined with radial basis function (RBF) neural network to improve the accuracy of 3-month-ahead hake catches forecasting of the fisheries industry in the central southern Chile. The general idea of the proposed forecasting ...
