Semilocal convergence of Newton-like methods under general conditions with applications in fractional calculus

open access: yesJournal of Numerical Analysis and Approximation Theory, 2015
We present a semilocal convergence study of Newton-like methods on a generalized Banach space setting to approximate a locally unique zero of an operator.

On the range of the derivative of a smooth mapping between Banach spaces

open access: yesAbstract and Applied Analysis, 2005
We survey recent results on the structure of the range of the derivative of a smooth mapping f between two Banach spaces X and Y. We recall some necessary conditions and some sufficient conditions on a subset A of ℒ(X,Y) for the existence of a Fréchet ...

Substantial Diel Changes of Cloud Adjustments to Aerosols in Ship‐Tracks

open access: yesGeophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Clouds adjust their albedo, amount and liquid water path to anthropogenic aerosols, and produce a climate forcing. Such cloud adjustments are complex functions of both environmental conditions and interaction time. However, direct observations of temporal changes in cloud adjustments are limited. Here, we develop a method to show observational

Seismic Evidence for Slab Tearing Beneath the Indo‐Myanmar Subduction Zone

open access: yesGeophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Slab tearing has been increasingly recognized as a key geodynamic process influencing the evolution of the eastern Himalayan syntaxis. However, whether, where and how the subducted Indian slab beneath the Indo‐Myanmar subduction zone has been torn remains poorly constrained.

On the semilocal convergence of Newton-type methods, when the derivative is not continuously invertible

open access: yesCubo, 2011
We provide a semilocal convergence analysis for Newton-type methods to approximate a locally unique solution of a nonlinear equation in a Banach space setting. The Frechet-derivative of the operator involved is not necessarily continuous invertible. This

On the Temporal Variability of Precipitation in Iraq: Arid‐Wet Years and Extreme Events

open access: yesInternational Journal of Climatology, Volume 46, Issue 7, 15 June 2026.
Daily and monthly precipitation data in Iraq display high seasonal to interdecadal variability, with arid and wet years that have very distinct seasonal cycles. Monthly rainfall is significantly correlated with the Indian Ocean Dipole. Extreme events are identified and classified as belonging to four different weather patterns, allowing to obtain daily

Construction and Application of GAN Enhanced Virtual Interpretation Model for Sports Communication

open access: yesEngineering Reports, Volume 8, Issue 6, June 2026.
This model is an end‐to‐end framework. Firstly, the style‐based generation network Style‐based GAN2 (StyleGAN2) is used to generate a highly realistic and adjustable static narrator portrait. Then, Bi‐directional Long Short‐Term Memory (Bi‐LSTM) is used to encode the Mel‐frequency Cepstral Coefficients (MFCCs), phonemes, and prosodic features of the ...

A frequency-domain formulation of the Fréchet derivative to exploit the inherent parallelism of the distorted Born iterative method

open access: yes, 2006
With its consideration for nonlinear scattering phenomena, the distorted Born iterative method (DBIM) is known to provide images superior to those of linear tomographic methods.

Stability Results for an Age-Structured SIS Epidemic Model with Vector Population

open access: yesJournal of Applied Mathematics, 2015
We formulate an age-structured SIS epidemic model with periodic parameters, which includes host population and vector population. The host population is described by two partial differential equations, and the vector population is described by a single ...
