    Differential Evolution-Based Extraction of Impedance Parameters for Wide-Band Equivalent Circuits

    Piotr Musznicki1, Marek Turzyński1, Lyu Guanghua2, Ghulam E Mustafa Abro3,*, Viola Gierszewska1, Arsalan Muhammad Soomar1, Syed Hadi Hussain Shah2

    CMC-Computers, Materials & Continua, Vol.89, No.1, 2026, DOI:10.32604/cmc.2026.082254 - 13 August 2026

    Abstract This paper presents an accurate and efficient methodology for parameter extraction in complex impedance models using Differential Evolution (DE), an evolutionary optimization technique. The proposed approach targets equivalent RLC circuit topologies and aims to match measured impedance characteristics across a wide frequency spectrum. By formulating the extraction process as a global optimization problem, DE enables precise identification of component values, even for high-order models with multiple resonances. The method is implemented in Python using open-source libraries, facilitating reproducibility and integration into broader modeling workflows. Validation is performed on both analytically derived resonant circuits and physically More >

    A Multi-Specialist Stacking Decoder of Cognitive Workload and a Decomposition of the Limits of Cross-Dataset Transfer in Electroencephalography

    Sugeng Rifqi Mubaroq1,*, Rolly Maulana Awangga2, Tegar Ditya Pragama1, Sidiq Fathummubin3, Ali Yusuf Abdulhaq1

    Intelligent Automation & Soft Computing, Vol.41, pp. 27-46, 2026, DOI:10.32604/iasc.2026.088039 - 11 August 2026

    Abstract Decoding cognitive workload from electroencephalography (EEG) underpins passive brain–computer interfaces and adaptive learning technology, yet practical decoders share two weaknesses: they rely on a single family of features, and their accuracy collapses on recordings from an unfamiliar device, montage, or task. We address both. We first build a multi-specialist stacking decoder that fuses complementary spectral, Riemannian, and spatial views through a meta-learner. Evaluated across two public corpora under the leave-one-subject-out MOABB benchmarking protocol, it outperforms the best single specialist on the binary workload contrasts, and the strongest of these effects survives family-wide false-discovery-rate correction. The… More >

    Study on Higher-Order Harmonic Calculation of Neutron Diffusion Equation and Its Application in Core Power Monitoring of the Gas-Cooled Microreactor

    Kui Hu, Peng Zhang*, Xiang Xiao, Yuan Xu, Yunhuang Zhang, Yuan Yuan, Zhiyuan Feng

    Energy Engineering, Vol.123, No.9, 2026, DOI:10.32604/ee.2026.078340 - 06 August 2026

    Abstract The rapid development of gas-cooled microreactors (GMRs) for remote and modular power supply necessitates highly efficient and autonomous core power monitoring systems. Traditional monitoring systems, such as those deployed in commercial power plants, rely on dense in-core instrumentation, whereas due to the limitation of space and simplicity in hardware designs, only sparse ex-core detectors are employed in microreactor designs. To address this challenge, this study proposes an advanced online power reconstruction approach based on the higher-order harmonic expansion. A dedicated higher-order harmonic calculation module was developed within a multi-group diffusion framework, capable of executing rapid… More >

    Effective Pore-Throat Sweep Limits and Microscopic Oil Mobilization during CO2-WAG Flooding in Low-Permeability Conglomerate Reservoirs

    Xiaoguang Wang1,2, Dehua Liu1,2,*, Zhenping Liu3, Zhen Luo3, Guihua Yang1,2, Zongfa Li1,2, Lijuan Huang1,2,*

    FDMP-Fluid Dynamics & Materials Processing, Vol.22, No.7, 2026, DOI:10.32604/fdmp.2026.079864 - 31 July 2026

    Abstract Low-permeability conglomerate reservoirs are characterized by complex pore structures and poor sweep efficiency, making the optimization of carbon dioxide-water alternating gas (CO2-WAG) injection critical for enhanced oil recovery. To evaluate the displacement performance of CO2-WAG and determine the lower limit of effectively swept pore throats, this study presents long-core flooding experiments conducted on cores from the KS Formation of the B Oilfield in the Junggar Basin under reservoir conditions (20.1 MPa and 58°C). Continuous CO2 flooding and CO2-WAG schemes with varying cycle numbers and gas-water ratios (GWRs) were systematically compared. In situ online nuclear magnetic resonance (NMR) monitoring… More >

    Comparative Physiological Responses of Two Bougainvillea Cultivars to Shade Conditions

    Nan Zhao1,2,*, Qianru Zhao1, Xiangyu Wu1, Jiawei Hong1, Luanmei Lu1

    Phyton-International Journal of Experimental Botany, Vol.95, No.7, 2026, DOI:10.32604/phyton.2026.083994 - 30 July 2026

    Abstract The growth and landscape application of Bougainvillea, a widely cultivated ornamental plant, are often influenced by light conditions. The effects of shade on two Bougainvillea cultivars, ‘Imperial Delight (ID)’ and ‘San Diego Red (SDR)’, cultivated under full sunlight (CK) and 50% shade (S) were investigated. Under shading, both cultivars presented decreased leaf thickness; increased chlorophyll a, b and total contents; and reduced light compensation points (LCPs) and dark respiration rates (Rds), reflecting morphological and photosynthetic acclimatization. Decreased superoxide dismutase (SOD) activity and malondialdehyde (MDA) contents indicated attenuated membrane lipid peroxidation. In ‘ID’, shading significantly reduced the leaf,… More >

    Can Causal Circuits Enable Efficient Spatial Reasoning for Geoinformatics in Large Language Models?

    Sahil Tripathi1, Manaswi Kulahara2, Abdul Khader Jilani Saudagar3, Hatoon S. AlSagri3,*

    CMES-Computer Modeling in Engineering & Sciences, Vol.148, No.1, 2026, DOI:10.32604/cmes.2026.083755 - 27 July 2026

    Abstract Spatial reasoning, defined as the ability to infer and compose relations among entities—is fundamental to geoinformatics applications such as spatial querying and map understanding. However, existing works such as Bidirectional Encoder Representations from Transformers (BERT)-based spatial Question Answering (QA) models and neuro-symbolic models rely on dataset-specific patterns, leading to shortcut learning, where reliance on superficial lexical cues rather than true relational understanding. Recent Large Language Models (LLMs)-based works, including fine-tuning and Chain-of-Thought (CoT) prompting, partially alleviate shortcut learning but remain limited by non-causal reasoning, where predictions depend on spurious correlations rather than stable relational structure. To address these… More >

    Hybrid Classical-Quantum Transfer Learning with Noisy Quantum Circuits

    Daniel Martín-Pérez1, Francesc Rodríguez-Díaz1, David Gutiérrez-Avilés2, Alicia Troncoso1, Francisco Martínez-Álvarez1,*

    CMES-Computer Modeling in Engineering & Sciences, Vol.148, No.1, 2026, DOI:10.32604/cmes.2026.082712 - 27 July 2026

    Abstract Hybrid classical-quantum architectures have emerged as a practical response to the data and compute demands of modern deep learning, since a pretrained classical backbone can carry the feature extraction while a compact quantum head provides the trainable component. Quantum transfer learning is the most active instance of this idea. However, existing quantum transfer learning pipelines have been evaluated in isolation, typically on a single software framework and without a structured treatment of noise or statistical significance, which makes it difficult to assess how this paradigm contributes over fair classical baselines. A methodological benchmark for quantum… More >

    Integrative Analysis Identified an Eight-Gene Risk Signature Linked to CDK7 and Explored Its Association with HCC Progression via RelA Phosphorylation

    Bin Lan1, Jie Tan1, Qing Wang1, Siyuan Zeng2,*

    Oncology Research, Vol.34, No.8, 2026, DOI:10.32604/or.2026.081711 - 16 July 2026

    Abstract Backgrounds: Cyclin-dependent kinase 7 (CDK7) plays key roles in transcription and cell cycle regulation, and its inhibition has been proposed as a potential therapeutic strategy for hepatocellular carcinoma (HCC). The primary research objective of this study is to identify and validate CDK7-associated prognostic genes in HCC using bioinformatics approaches, construct a reliable prognostic risk model, and explore the functional role of CDK7 in HCC progression through in vitro and in vivo experiments, with a specific focus on its association with RelA/p65 phosphorylation, so as to provide evidence supporting CDK7 as a potential prognostic biomarker and therapeutic target for… More >
