Some results for Volterra integro-differential equations depending on derivative in unbounded domains

Ratio Mathematica, 2019
In this paper we study the existence of continuous solutions of an integro-differential equation in unbounded interval depending on derivative This paper extend some results obtained by the authors using the technique developed in their previous paper ...

Fragmentation–Coagulation Processes With Advection or Diffusion in Space

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT In this paper, we consider a continuous fragmentation–coagulation model in which the reacting particles can be transported in physical space through either advection or diffusion. We prove new results on the generation of C0$$ {C}_0 $$‐semigroups with parameter and use them to show that the abstract Cauchy problem associated with a more ...

An Extension on the Local Convergence for the Multi-Step Seventh Order Method with ψ-Continuity Condition in the Banach Spaces

Fractal and Fractional, 2022
The local convergence analysis of the multi-step seventh order method to solve nonlinear equations is presented in this paper. The point of this paper is that our proposed study requires a weak hypothesis where the Fréchet derivative of the nonlinear ...

Synthetic Imagery Improves Ecological Classification When Real Data Are Scarce, Not Direct Substitutes

Remote Sensing in Ecology and Conservation, EarlyView.
Image generation models can create synthetic ecological datasets and potentially alleviate limitations from sparse real data. Using 20 tree genera across community‐science and street‐view imagery, we tested whether synthetic images could replace or supplement real data for image classification.

Extended Convergence for Two Sixth Order Methods under the Same Weak Conditions

Foundations, 2023
High-convergence order iterative methods play a major role in scientific, computational and engineering mathematics, as they produce sequences that converge and thereby provide solutions to nonlinear equations.

Recent advances in polymeric chemically amplified positive resists: Materials and design strategies

Smart Molecules, EarlyView.
This review summarizes recent advances in the molecular design of positive chemically amplified resists, focusing on photoacid generators and polymer architectures. Key strategies for enhancing sensitivity—including self‐amplification effects, copolymerization of sensitive monomers, controlled polymerization, and photosensitized chemically amplified ...

A Newton-like Midpoint Method for Solving Equations in Banach Space

Foundations, 2023
The present paper includes the local and semilocal convergence analysis of a fourth-order method based on the quadrature formula in Banach spaces. The weaker hypotheses used are based only on the first Fréchet derivative.

DrLS: Distortion‐Resistant Lossless Steganography via Colour Depth Interpolation

CAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT The lossless data steganography is to hide a certain amount of information into a container image. Previous lossless steganography methods fail to strike a balance between capacity, imperceptibility, accuracy, and robustness, commonly vulnerable to distortion on container images.
