    ED-Ged: Nighttime Image Semantic Segmentation Based on Enhanced Detail and Bidirectional Guidance

    Xiaoli Yuan, Jianxun Zhang*, Xuejie Wang, Zhuhong Chu

    CMC-Computers, Materials & Continua, Vol.80, No.2, pp. 2443-2462, 2024, DOI:10.32604/cmc.2024.052285

    Abstract Semantic segmentation of driving scene images is crucial for autonomous driving. While deep learning technology has significantly improved daytime image semantic segmentation, nighttime images pose challenges due to factors like poor lighting and overexposure, making it difficult to recognize small objects. To address this, we propose an Image Adaptive Enhancement (IAEN) module comprising a parameter predictor (Edip), multiple image processing filters (Mdif), and a Detail Processing Module (DPM). Edip combines image processing filters to predict parameters like exposure and hue, optimizing image quality. We adopt a novel image encoder to enhance parameter prediction accuracy by More >

    CMMCAN: Lightweight Feature Extraction and Matching Network for Endoscopic Images Based on Adaptive Attention

    Nannan Chong1,2,*, Fan Yang1

    CMC-Computers, Materials & Continua, Vol.80, No.2, pp. 2761-2783, 2024, DOI:10.32604/cmc.2024.052217

    Abstract In minimally invasive surgery, endoscopes or laparoscopes equipped with miniature cameras and tools are used to enter the human body for therapeutic purposes through small incisions or natural cavities. However, in clinical operating environments, endoscopic images often suffer from challenges such as low texture, uneven illumination, and non-rigid structures, which affect feature observation and extraction. This can severely impact surgical navigation or clinical diagnosis due to missing feature points in endoscopic images, leading to treatment and postoperative recovery issues for patients. To address these challenges, this paper introduces, for the first time, a Cross-Channel Multi-Modal… More >

    Journal of Polymer Materials, Vol.41, No.2, pp. 69-86, 2024, DOI:10.32604/jpm.2024.052695

    Abstract This study aims to synthesize, characterize, and evaluate the photocatalytic efficiency of carboxymethyl cellulose (CMC) wrapped ZnONPs for the degradation of methylene blue (MB) dye under sunlight and also focuses on the effect of varying calcination temperatures on crystallite size of the synthesized ZnONPs@CMC. It focuses on developing biopolymer (CMC) wrapped ZnO nanoparticles (ZnONPs@CMC) at different calcination temperatures. ZnONPs@CMC are synthesized using zinc acetate dihydrate as a precursor under alkaline conditions, followed by adding capping agent CMC at various calcination temperatures ranging from 250°C to 650°C. The nanomaterials are characterized by UV-Vis, FTIR, and powder… More >

    Effect of Lightweight Aggregates Incorporation on the Mechanical Properties and Shrinkage Compensation of a Cement-Ground Granulated Blast Furnace Slag-Phosphogypsum Ternary System

    Yu Wang1,2, Mengyang Ma1,2,*, Yong Long1,2, Qingxiang Zhao1,2, Zhifei Cheng1,2

    FDMP-Fluid Dynamics & Materials Processing, Vol.20, No.8, pp. 1773-1784, 2024, DOI:10.32604/fdmp.2024.048695

    Abstract Shrinkage-induced cracking is a common issue in concrete structures, where the formation of cracks not only affects the aesthetic appearance of concrete but also potentially reduces its durability and strength. In this study, the effect of ceramsite sand addition on the properties of a ternary system of cement-ground granulated blast furnace slag (GGBFS)-phosphogypsum (PG) is investigated. In particular, the fluidity, rheology, hydration heat, compressive strength, autogenous shrinkage, and drying shrinkage of the considered mortar specimens are analyzed. The results indicate that an increase in PG content leads to a decrease in fluidity, higher viscosity, lower More >

    Integrative Analysis of Transcriptome and Phenolic Compounds Profile Provides Insights into the Quality of Soursop (Annona muricata L.) Fruit

    Yolotzin Apatzingán Palomino-Hermosillo1, Ángel Elpidio Díaz-Jasso2, Rosendo Balois-Morales1, Verónica Alhelí Ochoa-Jiménez1,3, Pedro Ulises Bautista-Rosales1, Guillermo Berumen-Varela1,*

    Phyton-International Journal of Experimental Botany, Vol.93, No.7, pp. 1717-1732, 2024, DOI:10.32604/phyton.2024.052216

    Abstract Soursop (Annona muricata L.) is a tropical fruit highly valued for its unique flavor, nutritional value, and health-promoting properties. The ripening process of soursop involves complex changes in gene expression and metabolite accumulation, which have been studied using various omics technologies. Transcriptome analysis has provided insights into the regulation of key genes involved in ripening, while metabolic compound analysis has revealed the presence of numerous bioactive compounds with potential health benefits. However, the integration of transcriptome and metabolite compound data has not been extensively explored in soursop. Therefore, in this paper, we present a comprehensive analysis… More >

    Summer Warming Limited Bud Output Drives a Decline in Daughter Shoot Biomass through Reduced Photosynthetis of Parent Shoots in Leymus chinensis Seedlings

    Song Gao1, Ruocheng Xu2, Lin Li3, Jiao Wang2, Nian Liu2, Johannes M. H. Knops4, Junfeng Wang2,*

    Phyton-International Journal of Experimental Botany, Vol.93, No.7, pp. 1667-1675, 2024, DOI:10.32604/phyton.2024.051548

    Abstract Understanding how summer warming influences the parent and daughter shoot production in a perennial clonal grass is vital for comprehending the response of grassland productivity to global warming. Here, we conducted a simulated experiment using potted Leymus chinensis, to study the relationship between the photosynthetic activity of parent shoots and the production of daughter shoots under a whole (90 days) summer warming scenario (+3°C). The results showed that the biomass of parents and buds decreased by 25.52% and 33.45%, respectively, under warming conditions. The reduction in parent shoot biomass due to warming directly resulted from decreased… More >

    Fangye Liu1,#, Jiaping Qu1,#, Yajun Li1, Jiawei Fan1, Yumeng Cui1, Jingwen Wu1, Xueqi Gu1, Xia Li2,*, He Huang1,*

    Phyton-International Journal of Experimental Botany, Vol.93, No.7, pp. 1599-1621, 2024, DOI:10.32604/phyton.2024.051386

    Abstract Chrysanthemum × morifolium is a horticultural crop which plays a vital role in the flower industry with significant economic value and has a cultivation history of over three thousand years in China. The accumulation of anthocyanins is always affected by light. Here, we revealed that anthocyanin accumulation is highly dependent on light in ‘2021135’ genotype chrysanthemum, while it is light-independent in ‘2001402’ genotype chrysanthemum. However, no literature has been reported regarding the non-photosensitive chrysanthemum in anthocyanins light-independent synthesis pathways. Through the phenotype analysis of 44 F generations, we found that light-independence is a dominant trait which… More >

    Congenital Heart Disease, Vol.19, No.3, pp. 267-273, 2024, DOI:10.32604/chd.2024.051642

    Abstract The aorto-ventricular tunnel is a rare congenital cardiac anomaly. We present a case of aorto-ventricular tunnel diagnosed via fetal echocardiography. Emergency surgery was performed on the 2nd day of life to close the tunnel, located just in front of the right coronary ostium, due to the patient’s unstable health condition. The postoperative period revealed complete occlusion of the right coronary artery. Due to the patient’s stability, we opted not to reintervene on the right coronary artery. The patient fully recovered without the need for further coronary intervention. In cases of patients with an aorto-ventricular tunnel More >

    Numerical Simulation of Oil-Water Two-Phase Flow in Low Permeability Tight Reservoirs Based on Weighted Least Squares Meshless Method

    Xin Liu1,*, Kai Yan2, Bo Fang3, Xiaoyu Sun3, Daqiang Feng4, Li Yin5

    FDMP-Fluid Dynamics & Materials Processing, Vol.20, No.7, pp. 1539-1552, 2024, DOI:10.32604/fdmp.2024.047922

    Abstract In response to the complex characteristics of actual low-permeability tight reservoirs, this study develops a meshless-based numerical simulation method for oil-water two-phase flow in these reservoirs, considering complex boundary shapes. Utilizing radial basis function point interpolation, the method approximates shape functions for unknown functions within the nodal influence domain. The shape functions constructed by the aforementioned meshless interpolation method have δ-function properties, which facilitate the handling of essential aspects like the controlled bottom-hole flow pressure in horizontal wells. Moreover, the meshless method offers greater flexibility and freedom compared to grid cell discretization, making it simpler… More >
