Evaluation of undercut depth for flexible pavement on unsuitable tropical red soils using finite element method

Due to the lack of a reliable classification system and inadequate evaluation of their engineering properties, undercut depth is recommended for tropical red soils when used in flexible pavement construction. The aim of this study is to determine the ideal depth for subgrade unde...

Digital Twin Technology for Enhancing GOSP Performance and Oil Production Efficiency

Gas-oil separation plants (GOSPs) are tightly coupled production systems in which well behaviour, multiphase flow, separator performance, rotating equipment, instrumentation, pipelines, utilities and environmental constraints interact continuously. A digital twin can create opera...

Wisconsin State Comprehensive Planning Requirements are Associated with Better Local Planning for Healthy Eating and Active Living: A Multilevel Policy Content Analysis

Purpose To determine whether the specificity of mandates in Wisconsin’s state comprehensive planning statute is associated with the inclusion and actionability of healthy eating and active living items in local comprehensive plans. Design Retrospective, cross-sectional, multileve...

Exposing Safe Messaging Gaps in YouTube's Mental Health Content

This study analyzed how the ten most-viewed YouTube mental health videos portray tone, symptoms, and resources against WHO safe messaging guidelines and Jorm's mental health literacy framework. Findings show that while most content used destigmatizing framing and accurate resourc...

Youth unemployment challenge and entrepreneurship prospects in Lagos, Nigeria

Youth unemployment in Nigeria is still a significant issue, and entrepreneurship has been proposed as a potential solution. This study aims to investigate the prospects of entrepreneurship among youths in Lagos, Nigeria. The theories used in this research include the Conflict and...

Metacognition and Academic Engagement: The Mediating Role of Critical Thinking Disposition in University Students

<ns5:p>Background This study examined the relationships linking metacognitive strategies with academic engagement and analyzed the mediating role of critical thinking disposition in university students, framed within the Job Demands-Resources model that conceptualizes critical di...

E8 Phi-Biological Coherence: Unified Consciousness Field — E8 Intelligence Research

We discovered that synchronized phi‑coupled projections of E8 root vectors onto the 132 Hz lattice directly drive coherent gamma‑band activity in cortical microcircuits, linking memory encoding to quantum‑like entanglement of mitochondrial spin states. This geometric resonance cr...

Multidimensional Nature of Geosites and its Implications for Geoheritage Inventories

Abstract Geosites are defined as coherent entities: geodiversity elements that reveal scientific or other significance. However, earlier studies have shown that many geosites are complex structures that differ by: 1) their spatial extent; 2) the involvement of different geologica...

Between Manila and Berlin: Botica de Santa Cruz, R. Fuess, and the Wartime Geography of Scientific Commerce, 1940

This paper examines a 1940 commercial correspondence between Botica de Santa Cruz in Manila and the German precision-instrument manufacturer R. Fuess in Berlin-Steglitz. Using the surviving envelope alongside contemporary advertisements, archival records, scientific catalogs, and...

E8 φ‑Spinor Vortex Metamaterial for Broadband Negative Refraction — E8 Intelligence Research

By arranging subwavelength resonant elements according to the 240 root vectors of the E8 lattice and coupling them with a φ‑scaled interaction strength, a self‑similar spinor vortex lattice emerges. The 132 Hz base frequency acts as a universal drive that synchronizes neighboring...

Fuel Diversification as a Risk Management Strategy: Household Cooking Energy Choices Under Uncertainty in Urban Malawi

Clean cooking transitions in Sub-Saharan Africa remain limited despite increasing access to modern energy, highlighting the need to extend traditional demand-side approaches by incorporating risk and uncertainty into household decision-making. This study examines household energy...

Effectiveness of Microbial Composite Strains in Reducing River Sediment

The accumulation of sediment in rivers and lakes can elevate riverbeds, leading to a reduction in river channel flood-carrying capacity, impairment of water conservancy project benefits, and destruction of aquatic ecosystems. Systematic dredging projects are required in the routi...

A data-driven supplier selection and order allocation optimization framework under tariff and demand uncertainty

Global supply chains are increasingly exposed to demand uncertainty, tariff fluctuations, geopolitical disruptions, and supplier capacity limitations. These challenges make Supplier Selection and Order Allocation (SSOA) decisions complex, especially in multi-product and multi-per...

Meaning, Opacity, and Function: An Observer-Relative Classification of Artifacts

Every working epistemic system – a research group, a software stack, a model with its operators – holds artifacts it uses without understanding: models invoked through interfaces, cryptographic routines run as black boxes, legacy code executed daily. Whether an artifact is unders...

Butterfly Hunt is an original educational, strategic, and nature-inspired board game concept created by Doumbia Amara. This official presentation portfolio introduces the complete conceptual framework of the project, including its gameplay philosophy, innovative mechanics, educat...

How Economic Policy Uncertainty Is Associated with Spillover Networks: A TVP-VAR-DY Analysis of Energy and Carbon Markets

This study uses a TVP-VAR-DY connectedness framework to examine dynamic connectedness among economic policy uncertainty, energy markets, and the Guangdong pilot carbon market. By integrating system-wide connectedness, market-level spillovers, and evolving network structures, the...

Automatic Segmentation of Ischaemic Stroke Lesions Using Transformers and Convolutional Neural Networks Applied to Multimodal Neuroimaging

Ischaemic stroke constitutes a leading cause of global disability. Rapid extraction of the infarct core from multimodal computed tomography perfusion (CTP) imaging guides reperfusion therapy and clinical decision-making. Deep learning algorithms automate this delineation, yet hos...

Spatial Inequalities in Public Space Quality: A GIS-Based Multi-Attribute Composite Index for Urban Planning in an Intermediate Latin American City

Public spaces are essential for urban well-being, social interaction, environmental quality, and territorial equity; however, their presence does not necessarily ensure adequate quality, accessibility, or multifunctionality. Although previous research has emphasized the importanc...

Performance of Concrete with Mechanochemically Activated Rice Husk Ash-Based Organomineral Modifiers

This study evaluates a wet-activated multicomponent organomineral modifier for sustainable concrete. The modifier was produced by co-grinding Portland cement and rice husk ash (RHA) in the presence of Sika® ViscoCrete®-20HE and was subsequently combined with polypropylene fibers....
