Objective: To characterize the population dynamics and spatial distribution of in the flour warehouse, so as to provide the basic evidence for improving the sampling guidelines that are essential for effective pest monitoring and management.
Methods: The samples from flour warehouses of four localities were collected, examined and counted for in every month in Wuhu City. The dispersion pattern target, Iwao / regression analysis and Taylor power method were used for analyzing the spatial distribution pattern of in the flour warehouses.
Results: The peaks of population dynamics of were discovered in July and September, respectively. The indexes of dispersion were as follows： > 0, > 0, > 1. At the same time, the parameters in the equation of Iwao：=5.471+1.022 ( = 0.999) and Taylor： lg = 0.697+1.111 lg ( = 0.987) showed that the spatial distribution pattern of was assembled.
Conclusions: The peaks of population dynamics of in the flour warehouse are bimodal pattern, and the spatial distribution pattern of is assembled.

Attention Score-Based Multi-Vision Transformer Technique for Plant Disease Classification.

Department of AI & Big Data, Honam University, Gwangju 62399, Republic of Korea.
This study proposes an advanced plant disease classification framework leveraging the Attention Score-Based Multi-Vision Transformer (Multi-ViT) model. The framework introduces a novel attention mechanism to dynamically prioritize relevant features from multiple leaf images, overcoming the limitations of single-leaf-based diagnoses. Building on the Vision Transformer (ViT) architecture, the Multi-ViT model aggregates diverse feature representations by combining outputs from multiple ViTs, each capturing unique visual patterns.

Extracting fragmented cropland is essential for effective cropland management and sustainable agricultural development. However, extracting fragmented cropland presents significant challenges due to its irregular and blurred boundaries, as well as the diversity in crop types and distribution. Deep learning methods are widely used for land cover classification.

Radiofrequency ablation (RFA) is a minimally invasive procedure that utilizes localized heat to treat tumors by inducing localized tissue thermal damage. The present study aimed to evaluate the temperature evolution and spatial distribution, ablation size, and reproducibility of ablation zones in ex vivo liver, kidney, and lung using a commercial device, i.e.

The Academy of Applied Technical and Preschool Studies, Aleksandra Medvedeva 20, 18000 Nis, Serbia.
This paper presents a Regeneration filter for reducing near Salt-and-Pepper (nS&P) noise in images, designed for selective noise removal while simultaneously preserving structural details. Unlike conventional methods, the proposed filter eliminates the need for median or other filters, focusing exclusively on restoring noise-affected pixels through localized contextual analysis in the immediate surroundings. Our approach employs an iterative processing method, where additional iterations do not degrade the image quality achieved after the first filtration, even with high noise densities up to 97% spatial distribution.

Here we describe the synthesis and evaluation of a molecular corrosion sensor that can be applied in situ in aerospace coatings, then used to detect corrosion after the coating has been applied. A pH-sensitive molecule, 4-mercaptopyridin (4-MP), is attached to a gold nanoparticle to allow surface-enhanced Raman-scattering (SERS) for signal amplification. These SERS nanoparticles, when combined with an appropriate micron-sized carrier system, are incorporated directly into an MIL-SPEC coating and used to monitor the process onset and progression of corrosion using pH changes occurring at the metal-coating interface.
