    Abstract Backgrounds: Breast cancer metastasis remains the leading cause of mortality and frequently targets the bone. Breast cancer cells release soluble factors and extracellular vesicles that disrupt bone marrow (BM)/bone homeostasis, promoting osteoclastogenesis and the accumulation of senescent cells. In line with updated cancer hallmarks, senescent mesenchymal stem/ stromal cells (MSCs), osteoblasts, and osteocytes contribute to remodeling of the BM microenvironment, thereby favoring pre-metastatic niche (PMN) formation and subsequent bone metastasis. We previously demonstrated that untreated stage III-B breast cancer patients (BCPs) exhibit increased oxidative stress and elevated reactive oxygen species (ROS) levels, accompanied by senescent… More > Graphic Abstract

    External risk factors for smartphone addiction in adolescents: A systematic literature review

    Wanqing Lin1,2,*, Mohd Azrin Mohd Nasir1, Suzila Binti Ismail1

    Journal of Psychology in Africa, DOI:10.32604/jpa.2026.073231

    Abstract This systematic review synthesizes empirical research on external risk factors for adolescent smartphone addiction. Scopus and Web of Science were searched for English peer-reviewed empirical articles from 2008 onward; 28 met inclusion criteria (excluding non-adolescents, generic internet addiction, non-empirical work, or non-English). Thematic synthesis organized findings into three external risk domains—family, school, and peers—considering cultural/contextual mechanisms. Family dynamics (parental phubbing, harsh parenting, dysfunction), school stressors, and adverse peer relationships were identified as accumulating, direct and indirect contributors to smartphone addiction. These operate within a techno-ecological framework, where digital technologies amplify vulnerabilities and create new pathways More >

    Experimental and Numerical Optimization of Prestressed Anchor Cable Support for In-Situ Large-Span Tunnel Expansion with an Energy Balance Framework

    Ying Zhu1,2, Minghui Hu3, Shengxu Wang1,2, Xiaoliang Dong3,*, Xuewen Xiao1,2, Richeng Liu3, Meng Wang1,2, Zheng Yuan3

    CMES-Computer Modeling in Engineering & Sciences, DOI:10.32604/cmes.2026.076381

    Abstract In-situ enlargement of super-large-span tunnels can intensify excavation-induced unloading in the surrounding rock, increasing deformation demand and failure risk during construction. This study combines laboratory model tests with FLAC3D simulations to evaluate the stabilizing role of prestressed anchor cables and to establish an energy-balance framework for support optimization. Comparative model tests of existing and enlarged tunnel sections, with and without anchors, show that reinforcement increases load-carrying capacity, reduces displacement, and confines damage to more localized zones. The numerical simulations reproduce displacement fields, shear-strain localization, and plastic-zone evolution with good agreement against the experimental observations. The energy More >

    Task Offloading and Edge Computing in IoT—Gaps, Challenges and Future Directions

    Hitesh Mohapatra*

    CMC-Computers, Materials & Continua, DOI:10.32604/cmc.2026.076726

    Abstract This review examines current approaches to real-time decision-making and task optimization in Internet of Things systems through the application of machine learning models deployed at the network edge. Existing literature shows that edge-based distributed intelligence reduces cloud dependency. It addresses transmission latency, device energy use, and bandwidth limits. Recent optimization strategies employ dynamic task offloading mechanisms to determine optimal workload placement across local devices and edge servers without centralized coordination. Empirical findings from the literature indicate performance improvements with latency reductions of approximately 32.8% and energy efficiency gains of 27.4% compared to conventional cloud-centric models.… More >

    NetVerifier: Scalable Verification for Programmable Networks

    Ying Yao1, Le Tian1,2,3, Yuxiang Hu1,2,3,*, Pengshuai Cui1,2,3

    CMC-Computers, Materials & Continua, DOI:10.32604/cmc.2026.075747

    Abstract In the process of programmable networks simplifying network management and increasing network flexibility through custom packet behavior, security incidents caused by human logic errors are seriously threatening their safe operation, robust verification methods are required to ensure their correctness. As one of the formal methods, symbolic execution offers a viable approach for verifying programmable networks by systematically exploring all possible paths within a program. However, its application in this field encounters scalability issues due to path explosion and complex constraint-solving. Therefore, in this paper, we propose NetVerifier, a scalable verification system for programmable networks. To… More >

    Local-Stress-Induced Detwinning in Nanotwinned Al without Shear Stress on Twin Boundaries

    Wenchao Shi1, Tao Wei2, Chuan Yang3, Qichao Fan3, Hongxi Liu4, Bin Shao5,*, Peng Jing4,*

    CMC-Computers, Materials & Continua, DOI:10.32604/cmc.2026.075293

    Abstract Enhancing the strength of nanotwinned aluminum (Al) is essential for the development of next-generation high-end chip technology. To better understand the detwinning behavior of nanotwinned Al under conditions with no resolved shear stress acting on the twin boundaries, we conducted molecular dynamics simulations of uniaxial tensile deformation in nanotwinned single-crystal Al at room temperature. Detwinning is observed only when the twin boundary spacing is 7.01 Å. At larger spacings, twin boundaries remain parallel to the loading direction, with no rotation or bending, indicating negligible migration. Detwinning is triggered by localized stress from dislocation interactions, with More >

    Hierarchical Attention Transformer for Multivariate Time Series Forecasting

    Qi Wang, Kelvin Amos Nicodemas*

    CMC-Computers, Materials & Continua, DOI:10.32604/cmc.2026.074305

    Abstract Multivariate time series forecasting plays a crucial role in decision-making for systems like energy grids and transportation networks, where temporal patterns emerge across diverse scales from short-term fluctuations to long-term trends. However, existing Transformer-based methods often process data at a single resolution or handle multiple scales independently, overlooking critical cross-scale interactions that influence prediction accuracy. To address this gap, we introduce the Hierarchical Attention Transformer (HAT), which enables direct information exchange between temporal hierarchies through a novel cross-scale attention mechanism. HAT extracts multi-scale features using hierarchical convolutional-recurrent blocks, fuses them via temperature-controlled mechanisms, and optimizes More >
