Abstract OAuth authorization ecosystems contain a large and diverse collection of capabilities distributed across multiple cloud platforms. Although previous studies have investigated OAuth security, privacy, and authorization management, the structural organization of authorization capabilities across providers has received limited attention. This study presents a cross-provider structural analysis of OAuth capabilities from seven major authorization platforms. A unified capability dictionary is constructed by normalizing publicly documented OAuth scopes into a common semantic representation. The normalized capabilities are transformed into an undirected semantic topology in which nodes represent capabilities and edges represent deterministic semantic relationships.

Abstract Internet of Things (IoT) intrusion detection systems face increasing pressure from adversarial attacks that can manipulate not only feature vectors but also the relational structure on which graph based models rely. This paper proposes Trust Filtered GraphSAGE (TF-SAGE), a graph based intrusion detection system (IDS) pipeline in which edges are assigned trust scores, filtered before message passing, and coupled with uncertainty aware inference to reduce overconfident decisions under unstable neighborhoods. The model is evaluated on NF-ToN-IoT-v2 as the main benchmark and CICIIoT2025 as an independent confirmation benchmark under the same FSAA and GSAA evaluation protocol.… More >

Abstract Scanning tunneling microscopy (STM) images are frequently affected by low-frequency vibrations, substrate-induced background variations, and bias-dependent contrast changes, which degrade molecular feature responses and hinder reliable segmentation. To address this challenge, we develop an STM-oriented Feature Pyramid Network (FPN) + Dual-Path Intensity Calibration (DPIC) framework by adapting a DPIC module, originally derived from a cloud-noise calibration mechanism, to the specific characteristics of STM molecular images. In this framework, DPIC is reformulated as a noise-aware feature calibration module that suppresses low-response background interference while preserving foreground molecular contours. We integrated DPIC into the FPN architecture and… More >

Traditional emotion recognition often uses 2D videos and pictures to stimulate emotions, which do not provide an immersive feeling. Virtual reality (VR) can provide a more immersive and realistic experience, and recent studies are beginning to utilize EEG for emotion recognition in VR. However, due to the limited information on single-modal features, it is not possible to fully recognize individual emotions.

To counteract this, researchers have worked to create methods of data concealment, hiding the existence of sensitive data itself from prying eyes. However, many of these methods lack the necessary ability to balance imperceptibility and payload capacity. In addition, different from generic images, medical images must preserve their structural and visual integrity, requiring frameworks that prioritize maintaining high similarity between images or, at times, complete recovery of the original image.… More >

Abstract Growth of cancerous cells is unpredictable, and their effects vary across organs and levels of aggression. Identification of the pattern, size, and shape of the growth helps assess severity for better treatment. The proposed LiteDKT-Net combines the DK-IRB (Diverse Kernel Inverted Residual Block) block and Transformer to target conceptual information about shape and location. For better edge detection, LiteDKT-Net uses GAG (Group Attention Gate) followed by CBAM (Convolutional Block Attention Module). LiteDKT-Net is a lightweight encoder-decoder-based network optimized for accurate brain tumor segmentation. The network parameter optimization and reduced computational complexity in LiteDKT-Net enable high… More >

Abstract The operation of complex equipment is typically monitored by multiple sensors, and the vast amount of status data generated from this monitoring provides strong support for predicting the remaining useful life (RUL). Due to the influence of unstable operational conditions, the degradation trajectory of the equipment often exhibits a high degree of nonlinearity. Conventional approaches for processing univariate time series data often struggle to effectively identify inherent degradation trends and unstable fluctuations, while exhibiting limited capability in comprehensive modeling of multi-source time series data. This paper proposes a novel spatiotemporal neural network for RUL prediction.… More >

Abstract Feature selection (FS) plays a crucial role in machine learning by reducing data dimensionality and improving learning efficiency. In many real-world scenarios, label information is unavailable, making unsupervised FS particularly important. While Genetic Algorithm (GA) offers a powerful global search mechanism for subset selection, it often suffers from premature convergence and struggles to refine solutions in complex search spaces. To address these limitations, we propose a hybrid GA that integrates an information-theoretic local search strategy for unsupervised FS. The proposed method integrates an information-theoretic local refinement procedure, consisting of DEL and ADD operations based on… More >

Abstract The Artificial Protozoa Optimizer (APO) is a population-based metaheuristic for numerical optimization and engineering design. However, its stochastic initialization and limited local refinement can reduce performance on non-convex, discontinuous, and high-dimensional landscapes. To address these issues, this paper proposes an enhanced Artificial Protozoa Optimizer with a multi-strategy framework (EAPO). The method incorporates three mechanisms: a Symmetry-Enhanced Latin Hypercube Initialization (SELHI) strategy to improve the uniformity of the initial population, an Adaptive Phase Equilibrium Strategy (APES) to regulate the exploration–exploitation balance using iteration progress and population diversity, and an Adaptive Elite Perturbation Strategy (AEPS) to strengthen More >

Steganography, which conceals confidential information within ordinary transmissions, has emerged as a promising approach to strengthen security and privacy in IoT environments. However, despite the growing body of work, existing surveys often address steganography in general contexts without systematically analyzing its adaptation to the unique constraints of IoT systems.

Abstract Robust scene-level classification and semantic understanding from aerial and disaster-related imagery are essential for intelligent vision systems deployed in emergency response, UAV-based monitoring, and safety-critical environments. However, existing deep learning approaches, including convolutional neural networks and Vision Transformers (ViTs), often struggle to simultaneously capture fine-grained local object characteristics and global semantic scene context, while also lacking reliable uncertainty estimation mechanisms for trustworthy decision-making.

Abstract To address the challenge of precise station-keeping for underactuated unmanned surface vehicles (USVs) in unknown current environments, our team previously proposed a solution based on a “virtual anchoring” method. However, field tests revealed that the inherent “virtual anchor line” constraint limits positioning accuracy. This work introduces a novel control strategy to overcome the aforementioned issue, which enables accurate unmanned surface vehicle (USV) station-keeping by significantly reducing the distance constraint inherent to traditional virtual anchoring.

Abstract Recommender systems can alleviate information overload by producing item recommendations tailored to user preferences. The performance usually relies on rich user-item interaction data; however, missing entries introduce sparsity that substantially degrades performance. Early work primarily treated rating imputation as a preprocessing mechanism for mitigating sparsity and alleviating cold-start issues through explicit matrix completion. More recently, missing-data estimation has evolved beyond static preprocessing toward broader inference-oriented paradigms, including pseudo-label estimation, counterfactual inference, and debiasing mechanisms integrated directly into the learning objective. In this paper, we present a structured review of rating imputation and inference-oriented missing-data estimation… More >
