Abstract Background: In March 2026, Nigeria’s financial sector experienced a cascading cybersecurity breach that compromised both a commercial bank and the nation’s primary government payment infrastructure. Objective: This paper provides the first academic analysis of the Sterling Bank–Remita chain breach, examining how a single unpatched vulnerability led to the exposure of approximately 900,000 customer records and 3 terabytes of national payment data. Methods: Using open-source intelligence (OSINT) methodology and the MITRE ATT&CK framework (version 16), the attack chain was reconstructed from actor-published artefacts on the spear.cx cybercrime forum, cross-referenced with regulatory statements and vulnerability databases.

Abstract Objective: To develop a low-cost automated cataract severity classification system operating on standard consumer-grade colour photographs of the eye, without specialised ophthalmic hardware. Methods: A hybrid framework was designed that fuses deep features from a Convolutional Neural Network (CNN) with five handcrafted Grey-Level Co-occurrence Matrix (GLCM) and intensity descriptors—mean intensity, uniformity, standard deviation, contrast, and energy—extracted from a Hough-circle-localised pupil Region of Interest (ROI). A multi-class Support Vector Machine (SVM) with Radial Basis Function (RBF) kernel classifies each image into one of four severity grades: normal, immature, mature, or hypermature cataract. Results: The proposed fused system More >

Abstract Urban blue spaces are increasingly recognized as critical components of sustainable cities. However, a significant gap exists in understanding their role not just as recreational areas, but as functional mobility corridors, especially within urban fabric of Eastern Europe countries. This study addresses this gap by assessing the accessibility and integration potential of blue infrastructure within Bucharest, Romania. The novelty of the research lies in the development of the Blue Areas Accessibility Index (BAAI), using a GIS-based Multi-Criteria Analysis (MCA). Eight spatial parameters were standardized using Likert scale and weighted using the Analytic Hierarchy Process to… More >

Abstract A landslide is the downslope movement of soil, rock, or debris driven by gravity, often triggered by natural or anthropogenic factors. The Philippines is highly susceptible to landslides due to its steep terrain, frequent typhoons, intense rainfall, and seismic activity, resulting in significant socioeconomic and environmental impacts. Despite increasing landslide occurrences in vulnerable coastal and mountainous municipalities in the Philippines, localized and integrated Geographic Information System (GIS)-based landslide risk assessments incorporating hazard, vulnerability, and exposure components remain limited in small island municipalities such as San Andres, Romblon. This study assesses landslide risk in the Municipality… More >

Abstract The hygroscopic growth of engine-emitted particulate matter in exhaust plumes is strongly influenced by surface wettability. In this study, molecular dynamics simulations were performed on biodiesel- and diesel-derived combustion-particle models constructed on a unified defective carbon framework to investigate wetting behavior under representative exhaust-plume temperature and humidity conditions. Under the reference condition of 333 K and a saturation ratio of 1.2, the equilibrium contact angles on smooth biodiesel, rough biodiesel, and rough diesel surfaces were 45.4°, 63.5°, and 95.5°, respectively. The trends in work of adhesion and interfacial hydrogen-bond statistics were consistent with the contact-angle… More > Graphic Abstract

Abstract In this study, selective and non-selective absorber-coated trays were employed to dry carrots and pears. Two trays with a selective absorber coating (1 mm thickness) were used, each loaded with 600 g of sliced carrots and pears. Similarly, two additional trays with a non-selective absorber coating were utilised. Furthermore, the performance of both selective and non-selective absorber-coated trays was compared with conventional open sun drying. The selective absorber-coated tray demonstrated higher thermal energy absorption and enabled the drying of carrots within 2 days, resulting in a weight loss of 529 g. In contrast, owing to… More >

Abstract Transient thermodynamic analysis of a multilayer phase-change material (PCM)–assisted evacuated tube solar collector (PCM–ETSC) is presented. A compact enthalpy-based numerical model is formulated to capture coupled heat transfer among the absorber tube, a mixed-mean heat-transfer fluid (HTF) control volume, and multiple PCM layers with staggered melting temperatures under time-dependent irradiance. Performance is evaluated using solar-referenced thermal and exergy efficiencies and reported over a sunlit window defined by G (t) > 0.1 G_max. For the baseline run, the simulated temperature ranges are Tf∈[298.000,306.489] and Tt∈[298.000,310.432] K with PCM, compared with Tf∈[298.000,306.774] and Tt∈[298.000,310.848] K without… More >

Abstract This paper introduces a novel hybrid method for Power System State Estimation (PS-SE) that effectively integrates the strengths of Weighted Least Squares (WLS) and the Extended Kalman Filter (EKF) through an adaptive weighting mechanism. The proposed method addresses key challenges in modern PS-SE, including measurement uncertainties, bad data detection and handling, and convergence reliability. By incorporating an adaptive weighting mechanism, the hybrid approach dynamically adjusts estimation parameters based on the quality of the measurements, enabling it to maintain high accuracy for clean data while demonstrating exceptional resilience against outliers and noisy measurements. The performance of… More >

Abstract Electric heavy-duty truck battery swapping stations (EHDT-BSS) are emerging as flexible resources for power systems due to their high controllability and significant power capacity. However, the participation of EHDT-BSSs in grid frequency regulation is severely constrained by the limited battery quantity and the high stochasticity of swapping demand, where forecasting errors can affect system reliability. To address these challenges, this paper proposes a two-stage optimization strategy for EHDT-BSSs participating in frequency regulation considering demand uncertainty. First, the basic operation mode of BSS is designed, and a deep learning-based method is utilized to forecast swapping demand. More >
