A remark concerning the paper "An equivalence between the convergence of Ishikawa, Mann and Picard iterations"

open access: yesJournal of Numerical Analysis and Approximation Theory, 2004
In this note we show that a result previously obtained by us [An equivalence between the convergences of Ishikawa, Mann and Picard iterations, Math. Commun., 8, pp.~15--22, 2003], holds under weaker assumptions.

Nonlinear Effects on the Convergence of Picard and Newton Iteration Methods in the Numerical Solution of One-Dimensional Variably Saturated–Unsaturated Flow Problems

open access: yesHydrology, 2017
Finite element discretization of the pressure head form of the Richards equation leads to a nonlinear model, which yields numerical convergence difficulties.

Power bounded prolongations and Picard-Lindel�f iteration

open access: yesNumerische Mathematik, 1990
The author continues several earlier studies of Picard-Lindelöf iteration of linear constant coefficient systems \(\dot x+Ax=f(t),\) \(x(0)=x_ 0\), where the matrix A is assumed to be split as \(A=M-N\) for iteration \(\dot x^ n+Mx^ n=Nx^{n-1}+f(t),\) \(x^ n(0)=x_ 0\) [see e.g. the author, ibid. 57, No.2, 147-156 (1990; Zbl 0697.65058)].

Phylogenomics of the American robin (Turdus migratorius) reveals hidden lineages and introgression

open access: yesJournal of Systematics and Evolution, EarlyView.
Phylogenomic analyses of Turdus migratorius uncover four previously unrecognized lineages, including a divergent Baja California lineage (T. m. confinis). The results reveal complex evolutionary relationships that depart from simple models of continuous divergence, supported by evidence of introgression between the Mexican lineage and its previously ...

Reactivating a Relaxation Exercise During Sleep to Influence Cortical Hyperarousal in Individuals With Frequent Nightmares

open access: yesJournal of Sleep Research, EarlyView.
ABSTRACT High‐frequency EEG activity during sleep, reflecting cortical hyperarousal, has recently been incorporated into aetiology models of nightmares. However, its precise role remains insufficiently understood because experimental approaches to manipulate hyperarousal during sleep are limited.

Commission pathways for sexual offences against children: A novel methodological approach exposing distinct pathways as a function of offending history

open access: yesLegal and Criminological Psychology, EarlyView.
Abstract Purpose Using neural network analysis, we examined how specific dispositional and situational factors influence pathways for the commission of sexual offending against children. Use of non‐linear multifactorial models is still developing in psychological and criminological research, making this a unique contribution to these fields.

Space-Time Discrete Picard Iterations

open access: yesInternational Journal of Applied and Computational Mathematics
Abstract The numerical solution of time-dependent systems is often carried out using a step-wise updating procedure known as marching in time or simply time-marching methods. They require completing previous steps to yield an update for the next time step.

Genetic Architecture of Southern Stem Canker Resistance in Elite Southern Soybean (Glycine max [L.] Merr.) Germplasm

open access: yesPlant Breeding, EarlyView.
ABSTRACT Southern stem canker (SSC), caused by the fungus Diaporthe aspalathi, is one of the major constraints to soybean (Glycine max [L.] Merr.) production in the southern United States and South America. Genetic resistance is the most effective strategy for managing SSC; however, the genetic architecture underlying resistance in elite southern ...
