FROM AWARENESS TO ACTION: HOW BROADCAST MEDIA ONE HEALTH MESSAGES SHAPE PUBLIC BEHAVIOUR IN SOUTH-SOUTH NIGERIA

This study examined how One Health messages disseminated through broadcast media shape awareness, perception, reaction and behaviour among broadcast journalists and members of the public in South-South Nigeria. The study was anchored on the Agenda Setting Theory, Diffusion of Innovation theory and the Health Belief Mod...

Scaling of phase-change relaxation in VOF simulations of convection-driven melting

Phase-change relaxation is commonly introduced in Volume-of-Fluid (VOF) simulations of melting through a relaxation rate that controls the conversion between phases. Although this parameter strongly influences interface evolution and temperature fields, its selection remains largely empirical and often varies from one...

The role of white matter microstructure in the association between childhood maltreatment and adult post-traumatic symptoms

Abstract Childhood maltreatment (CM) is a risk factor for adult post-traumatic symptoms and white matter (WM) alterations. It remains unknown how WM microstructure is affected alongside two common military conditions, post-traumatic stress disorder (PTSD) and mild traumatic brain injury (mTBI). Data from 299 participan...

Noncommutative Cultural Dynamics: A Unified State-Space Framework for Weakly and Strongly Correlated Cultural Fields

This work proposes a unified mathematical framework for cultural dynamics that integrates state-space modeling, noncommutative transition operators, correlation structures, and generational modes. The model distinguishes between weakly correlated cultural fields—typical of ancient and pre-modern societies—and strongly...

Noncommutative Cultural Dynamics: A Unified State-Space Framework for Weakly and Strongly Correlated Cultural Fields

This project develops a unified mathematical and computational framework for cultural dynamics based on noncommutative operators, state-space modeling, and multi-scale correlation structures. Cultural change is represented as the evolution of latent cultural fields that may be weakly correlated (ancient and pre-modern...

Collaborative-Guided Diffusion for Sequential Recommendation

Sequential recommendation aims to predict the next item that aligns with user preferences based on their historical interaction sequence. Traditional sequential recommendation methods can be seen as understanding-based approaches, where the next relevant item is determined by analyzing user historical interactions and...

PATE-TDPM: Differentially Private Tabular Data Synthesis on Long-Tailed Distribution

While the tension between sharing valuable data and safeguarding individual privacy has grown increasingly acute, differentially private data synthesis has emerged as a principled solution. Although a series of research has been conducted in this field, the effectiveness on datasets with long-tail distribution attribut...

Entity-Dependent Relation Learning for Knowledge Graph Completion

Knowledge graph completion (KGC) aims to predict missing relationships between pairs of entities. Recently, Message Passing Neural Networks (MPNNs) have been employed in KGC and demonstrated superior ability in embedding learning. Current methods, however, face two major dilemmas. One focuses on learning complex entity...

Semiconductor Physics Using Arrows: Ohm's Law, Density of States, Mobility and Conductivity from the Arrow Maxwell Equations

Ohm's law in its usual form, a current proportional to the electric field, does not describe a semiconductor device; therefore Shockley's equations replace it. They rest on empirical parameters: a mobility measured for each material and fitted to the field, a diffusion coefficient tied to it, and the carriers' lifetime...

Mode-Selective and Anharmonicity-Dependent Energy Transport in Cavity-Coupled Water

Abstract Recent experiments demonstrate the modification of chemical dynamics via cavity-enhanced vibrational energy transport. Here, we provide a microscopic account of both photonic and mode-selective energy transport using direct mesoscale on-the-fly simulations of cavity-modified transport under vibrational strong...

Probing Oxygen Transport in β-Cyclodextrin–Cyclohexane Crystal Nanochannels by Luminescence Quenching from Nanoseconds to Seconds

Molecular transport in nanochannels can deviate from normal diffusion and exhibit different regimes depending on the observation timescale. However, resolving them from nanoseconds to seconds remains challenging. Here, oxygen transport in β -cyclodextrin–cyclohexane supramolecular crystals containing solvent-filled nan...
