    A New Approach for Evaluating and Optimizing Hydraulic Fracturing in Coalbed Methane Reservoirs

    Xia Yan1, Wei Wang1, Kai Shen2,*, Yanqing Feng1, Junyi Sun1, Xiaogang Li1, Wentao Zhu1, Binbin Shi1, Guanglong Sheng2,3

    Energy Engineering, Vol.123, No.1, 2026, DOI:10.32604/ee.2025.070360 - 27 December 2025

    Abstract In the development of coalbed methane (CBM) reservoirs using multistage fractured horizontal wells, there often exist areas that are either repeatedly stimulated or completely unstimulated between fracturing stages, leading to suboptimal reservoir performance. Currently, there is no well-established method for accurately evaluating the effectiveness of such stimulation. This study introduces, for the first time, the concept of the Fracture Network Bridging Coefficient (FNBC) as a novel metric to assess stimulation performance. By quantitatively coupling the proportions of unstimulated and overstimulated volumes, the FNBC effectively characterizes the connectivity and efficiency of the fracture network.

    FeatherGuard: A Data-Driven Lightweight Error Protection Scheme for DNN Inference on Edge Devices

    Dong Hyun Lee1, Na Kyung Lee2, Young Seo Lee1,2,*

    CMC-Computers, Materials & Continua, Vol.86, No.2, pp. 1-17, 2026, DOI:10.32604/cmc.2025.069976 - 09 December 2025

    Abstract There has been an increasing emphasis on performing deep neural network (DNN) inference locally on edge devices due to challenges such as network congestion and security concerns. However, as DRAM process technology continues to scale down, the bit-flip errors in the memory of edge devices become more frequent, thereby leading to substantial DNN inference accuracy loss. Though several techniques have been proposed to alleviate the accuracy loss in edge environments, they require complex computations and additional parity bits for error correction, thus resulting in significant performance and storage overheads. In this paper, we propose FeatherGuard,… More >

    Phyton-International Journal of Experimental Botany, Vol.94, No.12, pp. 3861-3877, 2025, DOI:10.32604/phyton.2025.070988 - 29 December 2025

    Abstract Circadian biorhythms are fundamental in plant adaptability and development. To reveal the effect of organic and inorganic forms of Se, foliar treatments of dandelion with 0.26 mM Se solutions were practiced in two contrasting day times: in the morning with the highest levels of leaf Se and polyphenol (TP) and the lowest dry matter, and in the evening with the opposite characteristics. Compared to the control, the morning Se supply demonstrated a higher increase of root biomass (1.27–1.37 times), Se (1.82–2.85 times), TP content (1.42–1.44 times), and antioxidant activity (AOA) (1.47–1.48 times) than the evening… More > Graphic Abstract

    K. Wanga,b,*, G. L. Lianc, Y. F. Qiaod

    Chalcogenide Letters, Vol.22, No.10, pp. 889-904, 2025, DOI:10.15251/CL.2025.2210.889

    Abstract The remediation of acid mine drainage (AMD), characterized by its high concentrations of toxic metal ions and low pH, presents a significant environmental challenge. In this study, exfoliated two-dimensional MoS nanosheets were prepared using a liquid-phase ultrasonication method and evaluated for their efficiency in removing Cd²⁺, Cu²⁺, and Pb²⁺ from aqueous solutions. Detailed structural and morphological analyses confirmed that the exfoliation process significantly enhanced surface area, pore volume, and exposure of reactive sulfur sites. Through isotherm and kinetic modeling analyses, the adsorption behavior was found to align with the Langmuir model and pseudo-second-order kinetic equation, which implies More >

    Abstract Hydrangea macrophylla is a popular ornamental shrub with a lot of economic and aesthetic value. It is known for its different flower shapes (lacecap and mophead) and the way its flowers change color depending on the pH of the soil. Even though it is important for gardening, we still don’t know much about the molecular processes that lead to flower growth. The purpose of this study was to find and study SNP-related genes and transcription factors that are connected to the growth of H. macrophylla flowers. Genome-wide SNP analysis identified 11 SNPs associated with MYB transcription factors… More >

    Large-Volume Hydraulic Fracturing in Tight Gas Reservoirs: High-Efficiency Stimulation and Geological Adaptability Assessment

    Bo Wang1, Fuyang Wu2, Zifeng Chen2, Libin Dai1, Yifan Dong1, Xiaotao Gao3, Zongfa Li2,*

    FDMP-Fluid Dynamics & Materials Processing, Vol.21, No.11, pp. 2701-2719, 2025, DOI:10.32604/fdmp.2025.067298 - 01 December 2025

    Abstract Tight gas reservoirs are often characterized by pronounced heterogeneity and poor continuity, resulting in wide variability in production enhancement and net present value (NPV) for different geological parameter combinations (see e.g., the Ordos Basin). The conditions governing geological adaptability remain insufficiently defined. To address these challenges, this study integrates large-volume hydraulic fracturing, numerical production simulation, and economic evaluation to elucidate the mechanisms by which large-scale fracturing enhances fracture parameters in tight gas formations. The analysis reveals that, for identical proppant and fluid volumes, increasing the fracturing injection rate leads to longer and taller fractures. Over… More >

    Challenge and Hindrance Academic Stressors and University Students’ Well-Being: The Chain Mediating Roles of Meaning in Life and Academic Self-Efficacy

    Yezi Zeng1,*, Yufei Cong2

    International Journal of Mental Health Promotion, Vol.27, No.11, pp. 1663-1679, 2025, DOI:10.32604/ijmhp.2025.072125 - 28 November 2025

    Abstract Background: Academic stress is a critical factor influencing university students’ well-being. However, research has shown that stress is not a unidimensional construct; different types of stressors (challenge vs. hindrance) may lead to distinct outcomes. This study constructed a structural equation model (SEM) to examine the relationships between challenge and hindrance academic stressors and students’ well-being, as well as the mediating mechanisms. Methods: Data were collected from 836 undergraduates at six universities in China (58.4% female, 41.6% male; Mean age = 20.47 ± 1.46 years). Descriptive statistics, Pearson correlations, and SEM with 5000 bootstrap resamples were conducted… More >

    Journal of Renewable Materials, Vol.13, No.11, pp. 2091-2107, 2025, DOI:10.32604/jrm.2025.02025-0060 - 24 November 2025

    Abstract It is highly attractive for the catalysts prepared from renewable materials and/or industrial by-products. Herein, lignosulfonate (LS) as the by-product in the papermaking industry was utilized to fabricate Sn-containing organic-inorganic complexing catalysts (Sn(x)@LS) by a simple hydrothermal self-assembly process. The fabricated Sn(x)@LS played an excellent performance in the dehydration of xylose into furfural in the carbon tetrachloride (CTC)-water biphasic system, yielding 78.5% furfural at 180°C for 60 min. It was revealed that strong coordination between Sn4+ and the phenolic hydroxyl groups of LS created a robust organic-inorganic skeleton (-Ar-O-Sn-O-Ar-), simultaneously generating potent Lewis acidic sites, and More > Graphic Abstract
