Conditionals And Modalities In Constructive Quantum Logics, Juan P. Aguilera, Guillaume Massas
Mathematics, Physics, and Computer Science Faculty Articles and Research
We investigate logics that generalize both intuitionistic logic and quantum logic. In earlier work, we introduced Ex-logic, an extension of Holliday's fundamental logic that coincides with the intersection of orthologic and the implication-free fragment of intuitionistic logic. In this paper, we add an implication connective to Ex-logic and axiomatize iEx-logic, the intersection of full intuitionistic logic and orthomodular logic with the implication connective interpreted as the Sasaki hook. As a consequence, we obtain a characterization of the lattice of logics extending iEx-logic as the product of the lattice of intermediate logics and the lattice of orthomodular logics. We also explore …

Coastal Landforms Analysis Of Al-Kharrar Lagoon And Rabigh Coast Using Aster (Ast_L1t) Imagery, Western Saudi Arabia, Omar A. Alharbi
Journal of King Abdulaziz University: Marine Science
The current study sought to examine the coastal geomorphology throughout the entire length of the Al-Kharrar Lagoon, in addition to the coastal region of Rabigh City, situated on the western coast of Saudi Arabia. The mechanisms underlying the formation of the wide variety of natural land features were also studied. These include sandy, pebble and rocky beaches and sand dunes; intertidal areas; salt flats (sabkhas) and marshes; elevated, terraced or fringing coral reefs; water inlets; and the deposition of terrigenous or alluvial materials, all reflecting the swift transformation that has impacted the region. Evaluation of the ASTER (AST_L1T) data enabled …

This study evaluates the effectiveness of deep learning and machine learning models for classifying seabed images into three ecologically significant categories: algae, rocks, and sand. We investigated five models: ResNet50, VGG16, a custom-designed convolutional neural network (CNN), support vector machines (SVM), and random forests (RF). Deep learning models were fine-tuned on 1259 seabed images, with the custom CNN architecture optimized using depthwise separable convolutions and global average pooling. For SVM and RF, features were extracted using a pre-trained VGG16 network. Class weighting was applied to address potential imbalances in the dataset. The custom CNN achieved the highest validation accuracy (82.01%), …

Senior high school (SHS) students in the Philippines are required to produce various academic papers that adhere to the properties of well-written texts. However, studies found that SHS students encounter difficulties with writing across a variety of content and ideas, vocabulary, diction, sentence and paragraph structures, language usage, and referencing (Pablo et al., 2018; Urbano et al., 2021). Despite these concerns, they are expected to persevere and show interest in improving their writing skills. In this context, this quantitative-descriptive study aimed to analyze the potential influences of sociocultural factors on the writing mindset and grit of the SHS students in …

Deep learning-based malware classification using image representations has emerged as a highly effective paradigm for threat detection. However, training robust neural networks is frequently bottlenecked by data scarcity and severe class imbalances in real-world repositories. This study investigates the viability of using an autoregressive PixelCNN framework to synthesize high-fidelity, class-specific malware images to augment limited training distributions. Utilizing the benchmark Malimg dataset, we systematically evaluate a Convolutional Neural Network (CNN) classifier across varying ratios of synthetic-to-authentic data under strict data scarcity constraints (ranging from 10 to 80 authentic samples per family). Our experimental results reveal that while PixelCNN successfully replicates …
