Mechanical Performance and Moisture Sensitivity of Sand–Clay Composite Stabilized with Gum Arabic as Partial Cement Replacement for Pavement Foundations

Road construction requires foundation materials with high mechanical performance. Cement is the primary binder used to stabilize these materials, but its widespread use generates substantial CO2 emissions and environmental impacts. Reducing cement demand has therefore stimulated...

Maximal elements in the Hurwitz graph

The Hurwitz graph has as its vertices the maximal chains in the lattice of non-crossing partitions, with an edge between two chains which differ at exactly one place. Adin and Roichman introduced an order on this graph by choosing a base element and showed that the maximal elemen...

Sustainable Raw Earth–Straw Fiber Composites: Estimated Sound Insulation Potential and Building-Relevant Properties

This study presents a comprehensive multiphysics characterization of unstabilized raw earth and earth–wheat straw composites to address the scarcity of data regarding their acoustic performance. Four soils from the Champagne-Ardenne region were initially analyzed to evaluate the...

Uncertainty Quantification in Neural Networks for Latent-Driven Non-Gaussian Outputs

Uncertainty quantification (UQ) is essential for reliable predictions in artificial neural networks when latent sources of randomness produce non-Gaussian outputs for a given deterministic input. We propose UQ-ANN, a data-driven framework composed of two coupled subnetworks. The...

Ground-motion dataset for shallow earthquakes in Colombia

Abstract. The tectonics of Colombia is characterised by the interaction of multiple oceanic plates subducting beneath the continent, generating active transpressional deformation and a wide range of subduction-related and crustal earthquakes. We present a flatfile containing grou...

Foreign aid and power play: Political cycles in world bank’s procurement allocation

This paper examines the existence of political cycles in the awarding of World Bank procurement contracts around elections. We analyze elections in the home country of firms winning these contracts, distinguishing between firms based in the aid recipient country (i.e., domestic f...

Recruitment difficulties in the restaurant industry? A field experiment on discrimination in access to apprenticeships in Paris

Access to apprenticeships remains one of the least explored areas in field experiments on ethnic discrimination. We examine the restaurant sector in Paris, a field notoriously affected by severe recruitment challenges. Our correspondence test targets female students who are seeki...

Walking through the microclimate: potential and limits of two participatory thermal walks

Thermal walks have emerged as a participatory experimentation method that integrates both quantitative and qualitative approaches. Such experimentations are designed to capture real-time thermal perceptions in relation to diverse urban features, such as greenery, urban design, an...

Financial resources as a structuring force in women’s urban mobility: Practices, constraints, and strategies in Yaoundé

Research on transport patterns both in the Global South and the North has revealed the existence of gendered differences in mobility. Women are disproportionately affected by these differences. The existing, Africa-centered, literature on the subject has explored certain aspects...

Mechanisms Governing Rapid Stiffening and Subsequent Structuring in Sodium Carbonate‐Activated Glass Cullet Powder

ABSTRACT This study investigates the mechanisms governing rapid stiffening and subsequent structuring in sodium carbonate (Na 2 CO 3 )‐activated glass cullet powder. Pastes containing 5, 10, 15, or 25 wt% Na 2 CO 3 were monitored from the first minutes after mixing to 28 days by...

A Granger causality-guided multi-graph transformer framework for traffic flow forecasting

Accurate traffic forecasting is challenging because of the difficulty of capturing time-varying propagation and multi-scale spatio-temporal interactions. Most existing deep learning models only learn correlations rather than directional dependencies, which limits interpretability...

On the use of seismic noise studies for landslide rock block hazard assessment

As emphasized by Pazzi et al. 1 , robust constraints on rock-mass volume are essential for landslide hazard assessment. However, such estimates are inherently challenging due to (i) complex geometries, (ii) heterogeneous material properties, and (iii) poorly constrained boundary...

A memory of Paleozoic to Quaternary Greenhouse climates recorded in Southern African regolith

Abstract In this article, we explore the potential of iron-rich duricrust regoliths from old erosional anorogenic surfaces to record clues of the long-term continental paleoclimatic evolution. We coupled geochemical, mineralogical and geochronological analyses on iron oxides and...

Bourdieu in Greenland: coloniality of distinction and the geographies of cultural capital in student migration

How is distinction produced in Greenland? Notwithstanding the process of “Greenlandization”, access to dominant positions remains structured by the former colonial power. Greenland's peripheral status persists in access to cultural goods, the value ascribed to qualifications, and...

CEO stock ownership and firm default risk

Purpose This study examines the effect of chief executive officer (CEO) stock ownership on firm default risk. While equity-based incentives are expected to align managerial and shareholder interests and enhance firm survival, alternative mechanisms – such as CEO under-diversifica...

What kind of cars do people drive? Including fuel type and emission standards in a car ownership model

Car ownership models are essential for understanding travel behavior and informing transportation policy decisions. However, previous research on car ownership modeling has not addressed the determinants of car ownership related to pollutant emissions such as fuel type or emissio...

Detection of a Nirsevimab-Resistant RSV-B Variant (F:K68Q) in an Adult with Severe Infection

Respiratory syncytial virus (RSV) is recognized as a major cause of severe disease in adults, particularly those having cardiorespiratory comorbidities or immunosuppression. The recent deployment of monoclonal antibodies targeting the prefusion F protein could be used in the futu...

Perfectly matched layers for two-dimensional open waveguides: Semi-infinite Laguerre-based and unbounded-function finite-thickness formulations

This paper presents an alternative finite element method for the computation of trapped and leaky waves in two-dimensional elastic open waveguides, relying on a Laguerre spectral representation of perfectly matched layers (PMLs). Using a Gauss-Radau-Laguerre quadrature rule, the...

Harnessing Nonlinear Nanofluidic Rectification to Suppress Concentration Polarization

Abstract Electrokinetic transport in nanoscale systems has garnered significant interest because of its potential applications in desalination, molecular separation, and ion-selective devices. In particular, electroosmotic flow (EOF) through selective membranes offers a promising...

Mortars and plasters at Herod's Caesarea Maritima: integration of imported and local construction technologies

Abstract Building materials from different architectural elements at Herodian Caesarea Maritima (22–4 BCE ) provide evidence for a variety of compositions tailored to specific construction functions, demonstrating the extent of Roman technological influence on Herod's architectur...
