The journal Neural Networks has retracted a 2012 paper by a group of researchers from Spain for publishing what amounted to a repeat of a 2011 article in a different but closely related journal. Scientific publishing, alas, is not like Hollywood, where remakes of movies and TV shows is not only acceptable, it seems to be the only flavor producers are willing to taste.
The article was titled “Hopf Bifurcation Stability in Hopfield Neural Networks” — Hopf, for those keeping score at home, is Eberhard Hopf, a famous (and politically controversial) mathematician and founder of something called ergodic theory — and it came from scientists at the University of La Laguna, in the Canary Islands.
What are the chances of successfully duplicating publication in the Journal of Theoretical Probability? Not too high, it seems.
A pair of South Korean authors have gotten a five-year ban from the journal for double-publishing a paper in the math literature.
The article, “Convergence of Weighted Sums for Arrays of Negatively Dependent Random Variables and Its Applications,” was written by Jong-Il Baek and Sung-Tae Park of Wonkwang University in IkSan.
Here’s the notice, for “Homotopy perturbation method to obtain exact special solutions with solitary patterns for Boussinesq-like B(m,n) equations with fully nonlinear dispersion:” Read the rest of this entry »
The Journal of Multivariate Analysis has retracted a paper it was never meant to publish — a problem, it seems, of multivariate analyses.
The article, titled “Regression estimation with locally stationary long-memory errors,” came from a pair of statisticians in Chile, Wildredo Palma and Guillermo Ferreira.
