    QIMIG: A Quantum-Inspired Evolutionary Framework for Software Library Migration

    Yun Liu1, Jinghua Zhao1, Liang Ma1, Zijie Huang2,3,*, Lizhi Cai2,3, Jianxin Ge2,3
    CMC-Computers, Materials & Continua, DOI:10.32604/cmc.2026.084179
    Abstract Automated library migration reduces refactoring costs but challenges traditional evolutionary algorithms, which often suffer from premature convergence and poor recall in sparse, complex API mapping spaces. To address this, we propose QIMIG, a multi-objective optimization framework integrating quantum-inspired encoding with quality-aware and greedy heuristic filtering. QIMIG utilizes a probabilistic Q-bit representation to maintain population diversity and avoid local optima. Simultaneously, its heuristic components leverage historical usage context to filter semantic noise and guide the search toward valid mappings. Evaluated on 9 real-world migration rules derived from 57,447 open-source projects, QIMIG statistically significantly outperforms state-of-the-art baselines More >

    Data Mining and Uncertainty-Aware with Missing Modalities for Multimodal Sentiment Analysis

    Ying Cao1, Penghui Zhao1, Xinyu Qiao1, Ningfan Zhan1, Xiaomei Zou2,*
    CMC-Computers, Materials & Continua, DOI:10.32604/cmc.2026.084057
    Abstract Multimodal Sentiment Analysis (MSA) integrates diverse modalities to identify emotional states, yet performance often suffers in scenarios with missing data. In this situation, despite the promising results of recent methods, the failure of part methods to fully exploit the latent valid information contained in incomplete modalities may degrade predictive performance. Besides, to address the oversight of varying contributions across modalities to sentiment understanding, the score-based weighting schemes in the exhibited methods remain overly sensitive to data fluctuations, leading to unstable and unreliable predictions. To this end, we propose a novel method, Data Mining and Uncertainty-Aware… More >

    HiFreq-DETR: A Hierarchical Framework Synergizing High-Resolution Injection and Frequency-Aware Multi-Scale Interaction for Tiny Object Detection

    Linyu Dong1, Tao Li2, Hao Li2,*
    CMC-Computers, Materials & Continua, DOI:10.32604/cmc.2026.083042
    Abstract While Transformer-based detectors excel in global modeling, their efficacy in unmanned aerial vehicle (UAV)-based tiny object detection is limited by information loss during aggressive downsampling and the lack of high-frequency structural cues. To bridge this gap, we propose HiFreq-DETR, a dedicated framework that optimizes the synergy between spatial fidelity and semantic discriminability. The core innovation lies in its hierarchical information preservation strategy, which employs a ResNeSt14d backbone coupled with an S2 spatial injection path to recover critical high-resolution structural anchors, and introduces a frequency-selective interaction module to decouple target saliency from background noise.

    CMC-Computers, Materials & Continua, DOI:10.32604/cmc.2026.083047
    Abstract The modern sports streaming market is severely fragmented, forcing fans into costly, siloed platforms. While blockchain-based decentralized architectures offer a unified, interoperable sport streaming ecosystem, securely delivering commercial video over untrusted infrastructure remains a profound cryptographic challenge. Existing schemes fail to simultaneously support highly granular on-demand highlights and large scale dynamic live subscriptions. To resolve this, we propose a novel decentralized authorization architecture that systematically integrates existing cryptographic primitives into a decoupled three-layer protocol.

    EGAIN: Enhanced Generative Adversarial Networks for Imputing Missing Values

    Abolfazl Saghafi1,*, Soodeh Moallemian2, Miray Budak2, Rutvik Deshpande2
    CMC-Computers, Materials & Continua, DOI:10.32604/cmc.2026.082996
    Abstract Missing data remain a persistent challenge in statistical analysis and machine learning because many predictive methods require complete observations. Generative Adversarial Imputation Networks (GAIN) offer a flexible deep-learning approach for missing value imputation, but their practical use is limited by convergence instability, sensitivity to hyperparameter selection, and dependence on outdated software implementations. To address these limitations, we propose Enhanced Generative Adversarial Imputation Networks (EGAIN), a modernized extension of GAIN implemented in TensorFlow 2.x. EGAIN incorporates convolution-based generator and discriminator networks, a channel-stacked representation of the data and mask, and checkpoint-based training diagnostics to improve stability More >

    Abstract With the proliferation of Internet of Things (IoT) devices, accurate device fingerprinting of highly encrypted traffic has emerged as a critical challenge for ensuring network security. Existing deep learning models are either difficult to deploy in real-time due to excessive computational complexity (e.g., Transformers) or are limited in performance because their structure does not match the inherent hierarchy of traffic data (e.g., flattened state space models). Furthermore, a general lack of transparency in their decision-making processes restricts their trustworthiness in security-critical scenarios.

    Abstract To address trust-score drift and unsafe online adaptation under cross-domain attack-contaminated streams in Industrial Internet of Things (IIoT) edge environments, this paper proposes a risk-aware lightweight test-time adaptation (TTA) framework, named RaL-TTA, for dynamic trust evaluation of edge nodes. RaL-TTA constructs a low-dimensional robust feature space and a source-domain normal-entropy reference baseline, and performs selective online maintenance in the target domain through Kolmogorov–Smirnov (KS) drift detection, SafeBrake risk gating, Adaptive Batch Normalization (AdaBN) anchor protection, and budgeted sample-level safeguards. Low-risk batches are adapted by updating only lightweight Batch Normalization (BN) parameters, whereas high-risk batches freeze… More >

    (This article belongs to the Special Issue: Development and Application of Deep Learning and Image Processing)
    Abstract Underwater imaging facilitates the exploration of the underwater environment. However, irregular optical absorption and light scattering in water, ranging from clear to highly turbid conditions, often result in low visibility, color distortion, and blurriness in underwater images (UWIs). Conventional UWI enhancement methods are limited by inefficient physical modeling, while deep learning-based approaches are constrained by the scarcity of paired training datasets. In this work, we propose a hybrid learning framework for UWI enhancement that leverages the usefulness of both conventional and deep learning-based techniques. At first, we preprocess the UWIs using a revised underwater physical… More >

Differential Privacy (DP) offers formal protection by injecting randomness, but its practical impact on detection utility is not well understood, especially under class imbalance and for rare attacks. This paper presents a controlled empirical study of feature-level DP applied to security telemetry for intrusion detection. Using a fixed model and a fixed train–test split, we vary only the privacy budget and quantify how performance changes across standard metrics, including macro-averaged scores and per-class More >

    Abstract Lecture videos are widely used in modern education, yet answering questions from them remains challenging. Relevant information is often distributed across time and expressed through multiple modalities, including speech, slides, and visual content. Existing VideoQA approaches, including recent retrieval-augmented generation (RAG) methods, typically rely on static text representations or global video features. Consequently, they may retrieve evidence that is semantically relevant but temporally misaligned, leading to inaccurate or weakly grounded responses. In addition, dependence on external knowledge sources can introduce hallucinations and reduce reliability in educational settings. To address these limitations, we propose a temporally More >

    CMC-Computers, Materials & Continua, DOI:10.32604/cmc.2026.081065
    Abstract Federated learning (FL) enables collaborative model training without sharing raw data. However, in real-world applications, clients often exhibit statistical heterogeneity, missing classes, and long-tailed distributions, which can substantially degrade the generalization performance of conventional parameter aggregation and some personalization approaches. Moreover, distillation or alignment-based methods may suffer from unstable supervision and difficult optimization under highly heterogeneous settings. To this end, this paper proposes a novel method called FKD-RTM (Heterogeneous Federated Knowledge Distillation Based on Residual-Enhanced Tree-to-MLP Knowledge Transfer). The key idea is to decouple local teaching from globally aggregatable student learning: we introduce a Gradient… More >

    Abstract The rapid development of digital technology has facilitated data exchange and communication, while simultaneously increasing security threats such as data theft and manipulation. As personal data is highly confidential, effective protection mechanisms are required in the digital era. Audio steganography hides secret messages (payload) within audio signals; however, many existing approaches rely on a single stego-audio output, which can lead to information leakage during storage or transmission if the file is intercepted. This vulnerability allows an attacker to more easily reconstruct the steganographic scheme from a single output. To address this limitation, this study proposes… More >

    CMC-Computers, Materials & Continua, DOI:10.32604/cmc.2026.078282
    Abstract In recent years, anomaly detection in Wireless Sensor Networks (WSNs) has been widely studied using Graph Neural Networks and Transformer-based methods. However, in multi-node and multi-modal data scenarios, these approaches still face challenges such as insufficient extraction of spatiotemporal correlation features, limited modeling capabilities when relying solely on either time-domain or frequency-domain information, and high computational overhead. To address these issues, this work aims to develop an anomaly detection model that balances detection performance with computational efficiency, enabling effective identification of complex anomaly patterns.

    Abstract Periodic pattern mining plays an important role in revealing recurring behavioral regularities from temporal sequence data. Most existing approaches, however, are developed for single-sequence settings and rarely account for quantitative information or sequence-level constraints when patterns recur across multiple sequences. This limits their usefulness in practical scenarios, where a pattern is expected to be not only periodic but also quantitatively significant in a sufficiently large portion of sequences. In this work, we formulate the problem of mining High-Quantitative Periodic Frequent Patterns (HQPFPS) from multi-sequence databases and propose an efficient algorithm, termed MHQPFPS.

    Abstract Auditable autonomy is becoming a practical requirement for deploying large language model (LLM) agents in operational workflows where recommendations can trigger consequential actions. Many autonomy claims remain hard to evaluate because studies emphasize task completion or fluent explanations while underreporting tool privileges, verification conditions, rollback feasibility, and trace completeness. This review develops a decision-making–centered framework that treats autonomy as an auditable engineering property. It introduces a three-plane big data foundation: an evidence plane with provenance and freshness constraints; a decision-trace plane that records retrieval identifiers, tool invocations, intermediate checks, and policy evaluations; and an outcomes More >

A point defect was created by removing a single Os/I atom from the perfect crystal lattice of the OsI2 monolayer. For doping, we use an isovalent Ru element from the transition-metal family. Point defects and doping alter the band structure by creating new localized electronic states within the gap. Moreover, the electronic bands show a shift due to point defects.

    Abstract Large multimodal models (LMMs) can produce fluent radiology reports, yet two clinically important error modes remain common: unsupported assertions and missed findings. Optimizing both under open supervision remains difficult because many pipelines still rely on overlapping parser families during training and evaluation. This paper introduces Truth-Anchored Dual-Extractor Counterfactual-Constrained Training (TA-DECT), which combines an ontology-derived atomic finding interface with four coupled objectives: structured prediction, dual-extractor minimax consistency on generated reports, deterministic counterfactual selectivity under evidence removal, and label-anchored completeness.

    Abstract Multimodal sentiment analysis aims to fuse emotional information from data across different modalities to predict human emotional states. Although existing multimodal sentiment analysis methods have made significant progress, the heterogeneity between modalities still leads to an imbalance in feature space distribution, thereby hindering the effective learning and fusion of multimodal representations. In addition, the presence of emotion-irrelevant information in auxiliary modalities is another major factor contributing to differences in feature space distributions.

    Abstract Simultaneous localization and mapping (SLAM) must remain reliable when sensing suites and operating conditions vary across platforms and deployments. Beyond correspondence degradation, a dominant deployment failure mode is misweighted constraints: under distribution shift, uncertainty estimates can become miscalibrated, allowing a small set of overconfident factors to dominate iterative optimization and destabilize inference. This article presents conformal-calibrated foundation-factor graph SLAM (CF2-SLAM), a sensor-agnostic framework that combines frozen foundation representations with lightweight probabilistic factor heads that emit explicit residuals and covariances, and a classical factor-graph back-end for principled multi-modal fusion.

    (This article belongs to the Special Issue: AI-Driven Optimization for Secure and Sustainable Edge IoT Services)
    Abstract This review systematically analyzes Reinforcement Learning approaches for self-healing in energy-constrained secure edge IoT networks across 82 studies from 2020 to 2026. Unlike existing surveys that focus on general RL applications, the proposed review focuses on a three-level taxonomy that uniquely addresses edge IoT deployment realities through formulation-scope-hardware mapping. The work develops a novel three-level taxonomy classifying recovery scope (node, link, service, network), RL formulations (tabular, deep, multi-agent, model-based), and constraint integration (energy, latency, security, hybrid), revealing service migration dominance at 30% coverage and node recovery achieving 38% maximum energy savings.

    Exploring the Temporal Degradation and Drift of AS Path Inference

    Xionglve Li1, Changsheng Hou2,*, Yuzhou Huang3, Zhenyu Qiu1, Gang Hu1, Bingnan Hou1, Wei Dong1, Zhiping Cai1
    CMC-Computers, Materials & Continua, DOI:10.32604/cmc.2026.080452
    Abstract The Internet inter-domain paths, i.e., the AS paths, are important for network management, traffic engineering, and security. Due to business confidentiality, security, and privacy, the AS path information is non-public. Due to limited measurement resources, obtaining AS path information by measurement-based approaches is not scalable. Therefore, path inference approaches are proposed to broaden the availability of path information. These approaches assume that AS paths remain stable over a certain period of time, yet conflicting research findings question this assumption. Furthermore, the duration of the “certain period of time” is not clearly defined. Thus, we aim… More >

    CMC-Computers, Materials & Continua, DOI:10.32604/cmc.2026.079080
    (This article belongs to the Special Issue: Mechanical Behavior of Materials with Advanced Modeling and Characterization)
    Abstract The potential of nontoxic elastomers like polydimethylsiloxane (PDMS) and bioceramic hydroxyapatite (HA) crystals has been demonstrated in numerous advanced applications. However, their crosslinking behavior in a composite system has not yet been modeled through simulation. Therefore, we employed a simulation-based approach to construct initial unit cell models of PDMS and HA, and for the first time, created PDMS-HA molecular structures using Materials Studio (MS) software. Molecular dynamics (MD) methods were applied to gain deeper insight into the structural framework and physical properties of PDMS, HA, and PDMS-HA composite. Equilibrium state via Forcite, physical, chemical, and thermal… More >

    Global-Local Embedding Gating Network for Part-Wise Text-to-Motion Generation

    Chanyoung Kim, Jion Kim, Byeong-Seok Shin*
    CMC-Computers, Materials & Continua, DOI:10.32604/cmc.2026.080992
    Abstract Diffusion-based methods have substantially improved the performance of full-body Text-to-Motion (T2M) generation from natural language descriptions. Despite this progress, accurately capturing the fine-grained semantics of composite prompts remains challenging. Approaches that rely solely on a single global text condition often fail to retain part-specific semantic cues, leading to deviations in the motions of certain body parts from the intended descriptions. Recent methods have attempted to address this by incorporating both global and local conditions, yet these are typically combined using fixed ratios or applied in separate stages, which restricts their adaptability to evolving semantic requirements… More >

    Zhaoxu Zhou, Yanjiang Liu, Zibin Dai*, Junwei Li
    CMC-Computers, Materials & Continua, DOI:10.32604/cmc.2026.080072
    Abstract Stream ciphers are simple to implement and fast at encrypting and decrypting data, making them very important in information security. Boolean functions are a core part of stream ciphers. However, their mainstream hardware implementations face two main problems, including wasted area resources and excessive critical path delay. These issues limit the energy efficiency and integration level of stream cipher chips. To address these problems, this paper proposes an energy-efficient design method for a 64-bit Boolean function reconfigurable operation unit (BFROU), aiming to improve the computational efficiency of Boolean functions in stream ciphers.

    Abstract Wireless Sensor Networks (WSNs) play a vital role in smart city Internet of Things (IoT) applications, including environmental monitoring, intelligent transportation, and infrastructure management. However, limited battery capacity, uneven energy consumption, and inefficient clustering and routing mechanisms significantly reduce network lifetime, reliability, and scalability, especially in large-scale IoT deployments. Traditional routing protocols often rely on single-objective optimization or static clustering strategies, which fail to maintain long-term energy balance and stable communication performance. To address these challenges, this paper proposes iPAFAR, a Pareto-based multi-objective clustering and routing framework designed for IoT-enabled WSNs. The proposed model formulates… More >
