A Novel Image Steganographic Method Based on Enhanced PIWT and Modified Optimal Pixel Adjustment Process

IET Image Processing, Volume 20, Issue 1, January/December 2026.
This paper proposes a novel image steganographic method based on an enhanced Pyramid Integer Wavelet Transform (PIWT) combined with a Modified Optimal Pixel Adjustment Process (MOPAP). The PIWT enables integer‐to‐integer transformation, avoiding floating‐point computations and improving its suitability for efficient implementation.

Fixed Point Theorems in Neutrosophic Fuzzy Metric Space and a Characterization to its Completeness [PDF]

Neutrosophic Sets and Systems
The present research work aims to establish some basic conventional fixed point theorems such as the Banach fixed point theorem, Edelstein fixed point theorem and Kannan fixed point theorem, for a recently introduced topological space, known as the ...

A Neutrosophic Set‐Based Active Contour Model for Medical Image Segmentation

IET Image Processing, Volume 20, Issue 1, January/December 2026.
We propose a neutrosophic set‐based active contour model for accurate and efficient segmentation of magnetic resonance (MR) and retinal images. By combining neutrosophic truth, falsity, and indeterminacy subsets with a Heaviside‐based level set formulation, the method robustly handles noise, intensity inhomogeneity, and weak edges.

AIRP‐UNet: A Multimodal Brain Tumour Segmentation Method Based on Attention‐Guided Inverted Residual Pyramid Network

IET Image Processing, Volume 20, Issue 1, January/December 2026.
Glioma segmentation from multimodal MRI is challenging due to tumour heterogeneity and imaging noise. To address this, we propose AIRP‐UNet, an asymmetric hybrid network that integrates an attention‐guided inverted residual decoder and a pyramid pooling module to selectively focus on tumour regions and capture multi‐scale context.

Exploring Optimal Locations for Large‐Scale Grid‐Connected Solar Photovoltaic Installation Using Interval‐Valued Spherical Fuzzy MCDM With Multi‐Panel Techno‐Economic Assessment

IET Renewable Power Generation, Volume 20, Issue 1, January/December 2026.
Introduces an Interval‐Valued Spherical Fuzzy SIWEC‐SPOTIS approach for PV site selection. The proposed model is validated through rank reversal, sensitivity, and comparative study. Solar irradiation received the highest weight, while mean wind speed received the lowest. Tangail district was ranked the most suitable, while Shariatpur ranked the lowest.

Big Data and Innovation: The State of the Art and Future Research Directions

R&D Management, Volume 56, Issue 1, Page 3-36, January 2026.
ABSTRACT Companies are increasingly aware of the benefits that can come from using big data. Of the various ways firms can make use of big data, in our research we have focused specifically on its use for innovation. As there are still many aspects that need to be clarified in this respect, our study addresses the following research question: how can ...

Edelstein Fixed Point Theorem in Neutrosophic Metric Spaces With an Application to an SIR‐Type Epidemic Model

International Journal of Differential Equations, Volume 2026, Issue 1, 2026.
In this paper, utilizing the concept of neutrosophic metric spaces proposed by Kirisci and Simsek, we establish a fixed point theorem of Edelstein type within this framework. A numerical example is provided to illustrate the validity of the main result. Furthermore, we present an application to a general SIR‐type epidemic model.
