    Gas Production and Reservoir Settlement in NGH Deposits under Horizontal-Well Depressurization

    Lijia Li, Shu Liu, Xiaoliang Huang*, Zhilin Qi

    FDMP-Fluid Dynamics & Materials Processing, Vol.22, No.1, 2026, DOI:10.32604/fdmp.2026.073294 - 06 February 2026

    Abstract Identifying geohazards such as landslides and methane leakage is crucial during gas extraction from natural gas hydrate (NGH) reservoirs, and understanding reservoir settlement behavior is central to this assessment. Horizontal wells can enlarge the pressure relief zone within the formation, improving single-well productivity, and are therefore considered a promising approach for NGH development. This study examines the settlement response of hydrate-bearing sediments during depressurization using horizontal wells. A fully coupled thermal, hydraulic, mechanical, and chemical (THMC) model with representative reservoir properties (Shenhu region in the South China Sea) is presented accordingly. The simulations show that More >

    Physiological and Metabolic Responses of Red Leaf Lettuce (Lactuca sativa L.) under Low Pressure Conditions

    Wonkyu Yi, Jongseok Park*

    Phyton-International Journal of Experimental Botany, Vol.95, No.1, 2026, DOI:10.32604/phyton.2026.073450 - 30 January 2026

    Abstract Understanding plant responses under low-pressure conditions is important for developing closed cultivation systems that simulate space environments. This study aimed to assess the effects of different pressure levels on growth, photosynthesis, and secondary metabolite accumulation in red leaf lettuce (Lactuca sativa L. var. ‘Super Caesar’s Red’). Plants were cultivated for three weeks in sealed chambers under 101 kPa (atmospheric pressure), 66 kPa (moderate low pressure), and 33 kPa (severe low pressure). Growth analysis showed that leaf length and leaf area decreased significantly with reduced pressure, while chlorophyll content and SPAD values increased gradually. Photosynthetic measurements indicated More >

    Ab initio Investigation of Structural Units and Raman Vibrational Characteristics in Ge-Se-Te Glasses

    Xuecai Han, Yilin Tong, Jiaqi Bao, Kan Yu*

    Chalcogenide Letters, Vol.23, No.1, 2026, DOI:10.32604/cl.2026.075604 - 26 January 2026

    Abstract Chalcogenide glasses in the Ge-Se-Te system possess wide infrared transparency and strong optical nonlinearity, yet the microscopic origin of their vibrational behavior remains unclear. Using ab initio calculations, we analyzed Raman-active modes in GeSexTe4−x (x = 0–4) tetrahedra, edge-sharing tetrahedra, and ethane-like Ge2Se2xTe6−2x (x = 0–3) clusters. For GeSexTe4−x (x = 0–4) tetrahedra, the symmetric stretching vibrations exhibit two families: Ge-Se-dominated and Ge-Te-dominated modes, both showing monotonic redshifts as the number of same-type bonds increases. In edge-sharing tetrahedra, the Ge-Ch-Ge-Ch (Ch = Se or Te) four-membered-ring breathing frequency decreases with higher Te content, and a comparable softening is More >

    Thermal Insulation Performance of Natural Fibre-Reinforced Composites—A Comprehensive Review

    Raviduth Ramful*

    Journal of Renewable Materials, Vol.14, No.1, 2026, DOI:10.32604/jrm.2025.02025-0116 - 23 January 2026

    Abstract Typically used thermal insulation materials such as foam insulation and fibreglass may pose notable health risks and environmental impacts thereby resulting in respiratory irritation and waste disposal issues, respectively. While these materials are affordable and display good thermal insulation, their unsustainable traits pertaining to an intensive manufacturing process and poor disposability are major concerns. Alternative insulation materials with enhanced sustainable characteristics are therefore being explored, and one type of material which has gained notable attention owing to its low carbon footprint and low thermal conductivity is natural fibre. Among the few review studies conducted on… More > Graphic Abstract

    Thimerosal Inhibits Tumor Malignant Progression through Direct Action and Enhancing the Efficacy of PD-1-Based Immunotherapy

    Ping Wang1,2,#, Yan-Han Chen1,2,#, Ze-Tao Zhan1,2, Jun-Xiang Zeng1,2, Yu Chen3,4, Yuan Lin1,2, Tao Chen1,5,*, Wei-Jie Zhou1,2,5,*

    Oncology Research, Vol.34, No.2, 2026, DOI:10.32604/or.2025.071902 - 19 January 2026

    Abstract Background: Thimerosal is a mercury-containing preservative widely used in vaccines. This study aimed to investigate its potential antitumor effects and mechanisms in solid malignancies, particularly colorectal cancer (CRC) and melanoma. Methods: A combination of in vitro and in vivo approaches was employed. Cell proliferation, apoptosis, migration, and invasion were assessed using Cell Counting Kit-8 (CCK-8), colony formation, ATP viability, Western blotting, flow cytometry, wound-healing and Transwell assays. Subcutaneous, lung metastases, and Azoxymethane/Dextran Sulfate Sodium Salt (AOM/DSS)-induced colitis-associated CRC models were established to examine antitumor efficacy and safety. The functional role of mercury ions was validated using structural… More >

    Block-Wise Sliding Recursive Wavelet Transform and Its Application in Real-Time Vehicle-Induced Signal Separation

    Jie Li1, Nan An2,3, Youliang Ding2,3,*

    Structural Durability & Health Monitoring, Vol.20, No.1, 2026, DOI:10.32604/sdhm.2025.072361 - 08 January 2026

    Abstract Vehicle-induced response separation is a crucial issue in structural health monitoring (SHM). This paper proposes a block-wise sliding recursive wavelet transform algorithm to meet the real-time processing requirements of monitoring data. To extend the separation target from a fixed dataset to a continuously updating data stream, a block-wise sliding framework is first developed. This framework is further optimized considering the characteristics of real-time data streams, and its advantage in computational efficiency is theoretically demonstrated. During the decomposition and reconstruction processes, information from neighboring data blocks is fully utilized to reduce algorithmic complexity. In addition, a… More >

    Construction of MMC-CLCC Hybrid DC Transmission System and Its Power Flow Reversal Control Strategy

    Yechun Xin1, Xinyuan Zhao1, Dong Ding2, Shuyu Chen2, Chuanjie Wang2, Tuo Wang1,*

    Energy Engineering, Vol.123, No.1, 2026, DOI:10.32604/ee.2025.069748 - 27 December 2025

    Abstract To enhance power flow regulation in scenarios involving large-scale renewable energy transmission via high-voltage direct current (HVDC) links and multi-infeed DC systems in load-center regions, this paper proposes a hybrid modular multilevel converter–capacitor-commutated line-commutated converter (MMC-CLCC) HVDC transmission system and its corresponding control strategy. First, the system topology is constructed, and a submodule configuration method for the MMC—combining full-bridge submodules (FBSMs) and half-bridge submodules (HBSMs)—is proposed to enable direct power flow reversal. Second, a hierarchical control strategy is introduced, including MMC voltage control, CLCC current control, and a coordination mechanism, along with the derivation of… More >

    Hesitation Analysis with Kullback Leibler Divergence and Its Calculation on Temporal Data

    Sanghyuk Lee1, Eunmi Lee2,*

    CMC-Computers, Materials & Continua, Vol.86, No.2, pp. 1-17, 2026, DOI:10.32604/cmc.2025.070504 - 09 December 2025

    Abstract Hesitation analysis plays a crucial role in decision-making processes by capturing the intermediary position between supportive and opposing information. This study introduces a refined approach to addressing uncertainty in decision-making, employing existing measures used in decision problems. Building on information theory, the Kullback–Leibler (KL) divergence is extended to incorporate additional insights, specifically by applying temporal data, as illustrated by time series data from two datasets (e.g., affirmative and dissent information). Cumulative hesitation provides quantifiable insights into the decision-making process. Accordingly, a modified KL divergence, which incorporates historical trends, is proposed, enabling dynamic updates using conditional More >

    Abstract Objectives: Keratin 6A (KRT6A) has been implicated in the progression of multiple malignancies; however, its expression pattern and biological role in cervical cancer (CC) have not been elucidated. This study aims to investigate KRT6A expression in CC tissues and evaluate its effects on cellular proliferation, migration, and invasion, thereby assessing its potential as a biomarker and therapeutic target. Methods: Differentially expressed genes were screened from the Gene Expression Omnibus (GEO) dataset (GSE9750) using the thresholds |log2FC| > 2 and false discovery rate (FDR) < 0.05. Immunohistochemistry was performed to evaluate KRT6A protein expression in tumor… More >
