    Collaborative Decomposition Multi-Objective Improved Elephant Clan Optimization Based on Penalty-Based and Normal Boundary Intersection

    Mengjiao Wei1,*, Wenyu Liu2

    CMC-Computers, Materials & Continua, Vol.83, No.2, pp. 2505-2523, 2025, DOI:10.32604/cmc.2025.060887 - 16 April 2025

    Abstract In recent years, decomposition-based evolutionary algorithms have become popular algorithms for solving multi-objective problems in real-life scenarios. In these algorithms, the reference vectors of the Penalty-Based boundary intersection (PBI) are distributed parallelly while those based on the normal boundary intersection (NBI) are distributed radially in a conical shape in the objective space. To improve the problem-solving effectiveness of multi-objective optimization algorithms in engineering applications, this paper addresses the improvement of the Collaborative Decomposition (CoD) method, a multi-objective decomposition technique that integrates PBI and NBI, and combines it with the Elephant Clan Optimization Algorithm, introducing the… More >

    Rolling Bearing Fault Diagnosis Method Based on FFT-VMD Multiscale Information Fusion and SE-TCN Model

    Chaozhi Cai, Yuqi Ren, Yingfang Xue*, Jianhua Ren

    Structural Durability & Health Monitoring, Vol.19, No.3, pp. 665-682, 2025, DOI:10.32604/sdhm.2025.059044 - 03 April 2025

    Abstract Rolling bearings are important parts of industrial equipment, and their fault diagnosis is crucial to maintaining these equipment’s regular operations. With the goal of improving the fault diagnosis accuracy of rolling bearings under complex working conditions and noise, this study proposes a multiscale information fusion method for fault diagnosis of rolling bearings based on fast Fourier transform (FFT) and variational mode decomposition (VMD), as well as the Senet (SE)-TCNnet (TCN) model. FFT is used to transform the original one-dimensional time domain vibration signal into a frequency domain signal, while VMD is used to decompose the… More >

    Abstract Traditional Palestinian medicine uses Thymus capitatus (T. capitatus), a plant recognized for its therapeutic properties due to its high concentration of essential oils such as thymol and carvacrol, to treat skin diseases, gastrointestinal disorders, and respiratory infections. The present study was conducted to evaluate the antioxidant and anticancer activities of T. capitatus essential oil (EO). Moreover, this study employed computational methods including ADMET analysis and molecular docking. Using Gas chromatography-mass spectrometry (GC-MS) analysis, the phytochemical composition of T. capitatus essential oil was identified. The DPPH scavenging method was used to assess antioxidant activity. The Michigan Cancer Foundation-7 (MCF-7) and… More >

    Abstract Juniperus oxycedrus (J. oxycedrus) is a traditional culinary spice and medicinal herb with a longstanding history of ethnopharmacological applications across diverse cultures. While prior research has explored the biological activities and phytochemical constituents of extracts derived from its leaves and seed cones, the present study systematically investigates their mineral and phenolic profiles alongside their multifunctional bioactive potential. Inductively coupled plasma-atomic emission spectroscopy (ICP-AES) analysis revealed a substantial abundance of essential macro- and microelements. Reversed-phase high-performance liquid chromatography (RP-HPLC) further identified high concentrations of phenolic acids (e.g., p-coumaric acid) and flavonoids (e.g., rutin and quercetin). The extracts exhibited More >

    Electroless Deposition of Cu Using Dopamine as Flexible Conductive Materials

    Jinliang Luo, Dongliang Li, Yang Li, Miaojiao Wang, Xiaomin Kang, Zhitao Hu*

    Journal of Polymer Materials, Vol.42, No.1, pp. 125-140, 2025, DOI:10.32604/jpm.2024.059636 - 27 March 2025

    Abstract With the rapid development of flexible wearable electronic products, their application fields and demands are increasing, posing new challenges to flexible conductive materials. This paper selected flexible polydimethylsiloxane (PDMS) as the substrate. In order to enhance the adhesion between the substrate and the metal coating, dopamine and silanization were used to co-modify its surface. A conductive layer of metallic copper is deposited on its surface using an inexpensive, easy-to-use electroless plating technique. By optimizing the process conditions, it is found that a uniform copper layer of about 0.6 μm can be formed on the surface More >

    Preparation and Properties of Acrylonitrile Butadiene Styrene/Polycarbonate Composite Filament for Fused Deposition Modeling

    Shanlong Che, Guangliang Qu, Jin Ding*, Guochen Wang, Yunyan Hao, Dianchen Li

    Journal of Polymer Materials, Vol.42, No.1, pp. 221-236, 2025, DOI:10.32604/jpm.2025.058587 - 27 March 2025

    Abstract Acrylonitrile–butadiene–styrene (ABS) is the main material used in fused deposition modeling (FDM), which has good toughness and strength, but the single ABS material has poor heat resistance, which tends to cause warping and deformation during the printing process. Polycarbonate (PC) exhibits good performance in heat resistance, allowing it to maintain stable performance at higher temperatures. In this work, PC was used as a blending modifier to prepare five kinds of ABS/PC composite filaments, and the mechanical and thermal properties of the ABS/PC (Acrylonitrile–butadiene–styrene/Polycarbonate) composite filaments were studied and analyzed. Results showed that the glass transition… More >

    Gabrielle Yankelevich1,*, Jessica Swaim1, Ian Coate1, Margaret Stroud1, William Stallings1, Virgilio George2, M. Lance Tavana3, Harry Clarke1

    Canadian Journal of Urology, Vol.32, No.1, pp. 37-42, 2025, DOI:10.32604/cju.2025.064684 - 20 March 2025

    Abstract Objectives: To assess outcomes of rectourethral fistula repair utilizing a gracilis flap in a largely radiated cohort. Patients and Methods: We performed a retrospective review of all gracilis interposition flap reconstruction surgeries performed for RUF at a university hospital in South Carolina between January 2010 and June 2023. All repairs utilized a multidisciplinary approach with urology, colorectal, and plastic surgery teams. Post-operatively, patients were maximally drained with foley catheter and suprapubic tube (SPT). Initial voiding cystourethrogram (VCUG) was performed at 4 weeks post-repair. If there was a persistent leak, catheter drainage was maintained for 4 additional… More >

    ProNet: Underwater Forward-Looking Sonar Images Target Detection Network Based on Progressive Sensitivity Capture

    Kaiqiao Wang1,2, Peng Liu1,2,*, Chun Zhang1,2

    CMC-Computers, Materials & Continua, Vol.82, No.3, pp. 4931-4948, 2025, DOI:10.32604/cmc.2025.060547 - 06 March 2025

    Abstract Underwater target detection in forward-looking sonar (FLS) images is a challenging but promising endeavor. The existing neural-based methods yield notable progress but there remains room for improvement due to overlooking the unique characteristics of underwater environments. Considering the problems of low imaging resolution, complex background environment, and large changes in target imaging of underwater sonar images, this paper specifically designs a sonar images target detection Network based on Progressive sensitivity capture, named ProNet. It progressively captures the sensitive regions in the current image where potential effective targets may exist. Guided by this basic idea, the… More >

    A Base Station Deployment Algorithm for Wireless Positioning Considering Dynamic Obstacles

    Aiguo Li1, Yunfei Jia2,*

    CMC-Computers, Materials & Continua, Vol.82, No.3, pp. 4573-4591, 2025, DOI:10.32604/cmc.2025.059184 - 06 March 2025

    Abstract In the context of security systems, adequate signal coverage is paramount for the communication between security personnel and the accurate positioning of personnel. Most studies focus on optimizing base station deployment under the assumption of static obstacles, aiming to maximize the perception coverage of wireless RF (Radio Frequency) signals and reduce positioning blind spots. However, in practical security systems, obstacles are subject to change, necessitating the consideration of base station deployment in dynamic environments. Nevertheless, research in this area still needs to be conducted. This paper proposes a Dynamic Indoor Environment Beacon Deployment Algorithm (DIE-BDA)… More >
