An Effective Approach for Recognition of Crop Diseases Using Advanced Image Processing and YOLOv8

Food Science &Nutrition, Volume 14, Issue 2, February 2026.
The performance of processed images is evaluated using mean‐squared‐error and peak‐signal‐to‐noise ratio. After the processing phase, an advanced deep learning model, YOLOv8, was used for the segmentation and classification of crop diseases. Using a large dataset comprising 32 diseases to train our model, we implemented Transfer Learning using YOLOv8 ...

Generalized \((h,r)\)-harmonic convex functions and inequalities

International Journal of Analysis and Applications, 2018
Summary: The main aim of this paper is to introduce a new class of harmonic convex functions with respect to non-negative function \(h\), which is called generalized \((h,r)\)-harmonic convex functions. We derive some new Fejer-Hermite-Hadamard type inequalities for generalized harmonic convex functions. Some special cases are also discussed. The ideas

Modular and Automated Workflow for Streamlined Raman Signal Analysis

Journal of Raman Spectroscopy, Volume 57, Issue 2, Page 360-377, February 2026.
This study presents an automated workflow for preprocessing and analyzing Raman spectroscopy data, addressing key challenges such as noise suppression, baseline correction, and peak fitting using Voigt profiles. The method is validated on both synthetic and experimental spectra, demonstrating improved spectral fidelity and peak detection for biomedical

Solvability of invariant systems of differential equations on H2$\mathbb {H}^2$ and beyond

Mathematische Nachrichten, Volume 299, Issue 2, Page 456-479, February 2026.
Abstract We show how the Fourier transform for distributional sections of vector bundles over symmetric spaces of non‐compact type G/K$G/K$ can be used for questions of solvability of systems of invariant differential equations in analogy to Hörmander's proof of the Ehrenpreis–Malgrange theorem.

Theoretical Study of Electrostatic Embedding and Properties of a Novel Quinolinone‐Chalcone Crystal and a Comparative Analysis with Dihydroquinolinone Analogs

ChemistryOpen, Volume 15, Issue 2, February 2026.
This graphical abstract highlights the molecular framework, electronic features, and nonlinear optical response of the quinolinone–chalcone crystal QCCP. The left panel displays the full molecular structure and the electrostatic environment introduced by iterative charge embedding, illustrating the crystal‐packing–induced dipole enhancement observed in

Attractors and upper semicontinuity for an extensible beam with nonlocal structural damping

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, Volume 106, Issue 2, February 2026.
Abstract We analyze the asymptotic behavior of a class of extensible beam models governed by a nonlocal structural damping mechanism of the form φ(El)(−Δ)βut$\varphi (E_l)(-\Delta)^{\beta }u_t$, where β∈λ=(0,1]$\beta \in \lambda =(0,1]$. The coefficient φ$\varphi$ is a degenerate C1$C^{1}$‐function depending on the linear energy El$E_l$ of the system ...

Statistical Characteristics of Electron Precipitation During HSS‐ and ICME‐Driven Storms Observed by the EISCAT Radar

Journal of Geophysical Research: Space Physics, Volume 131, Issue 2, February 2026.
Abstract The 1–100 keV electron precipitation during storm time has been studied by applying the updated ELSPEC inversion method to field‐aligned electron density profiles measured by the EISCAT Tromsø radar at L = 6.5. The statistical properties of peak energy, total energy flux, and total number flux as a function of MLT have been studied for the two
