Effect of wetting-drying cycles on physical and mechanical behavior of soil-aggregate-cement mixtures

Transportes
Soil-aggregate-cement (SAC) mixtures have been used in Brazil as base and/or subbase in pavements of heavy and very heavy volume roads, however, still lacks standardized protocols concerning material dosage and assessment of its performance and ...

T‐800: An 800 Hz Data Glove for Precise Hand Gesture Tracking

SmartBot, EarlyView.
Hand motion capture provides critical insights into human dexterity and facilitates advancements in robotic manipulation, yet existing systems are limited by a trade‐off between temporal resolution and visual occlusion. Here, the authors present T‐800, a high‐bandwidth data glove achieving synchronized full‐hand motion capturing at 800 Hz.

Analysis of nonlinear responses of asphalt pavements under overloading and tropical climate temperature conditions

Case Studies in Construction Materials
The design of asphalt pavement in many developing nations still relies on an empirical approach, often leading to either premature failure of the pavement or overdesign.

High‐Density Iron Nanostructures Grown on Electrospun PVA/Pectin Fibers via Seed‐Mediated Strategy for As(V) Remediation

Small Methods, EarlyView.
A seed‐assisted anisotropic growth strategy enabling unprecedented iron loading and controlled anisotropic nanostructure formation on electrospun PVA/pectin nanofibers is presented. By decoupling nucleation and growth through sequential Fe2+ then Fe3+ doping, it achieves a 12‐fold increase in accessible iron content, producing rice‐grain‐like ...

Damage Investigation of the Preform Operations for the Production of Rings for Ring Rolling

steel research international, EarlyView.
Void evolution during the preforming operations of two industrial ring rolling process routes is investigated by combining metallographic characterization with a two‐scale finite element simulation approach. The results reveal that, despite differing initial void conditions, the preforming operations can be designed to effectively influence void ...

Rotation capacity of continuous reinforced concrete slab strips revisited

Structural Concrete, EarlyView.
Abstract Rotation capacity is a key characteristic of statically indeterminate reinforced concrete structures, as it (i) enables bending moment redistributions, whether intentionally introduced through optimized reinforcement layouts or arising from unforeseen self‐equilibrated stress states, and (ii) promotes large rotations at failure load, thereby ...

4D imaging of a porous carbonate rock under triaxial loading: quantitative correlation between local porosity and strain

Journal of Synchrotron Radiation, EarlyView.
A 4D X‐ray computed tomography experimental campaign was carried out on a porous carbonate rock to investigate the link between initial porosity and deformation modes. This paper presents the experiment and the methods used to explore this relationship.The study of the mechanical behaviour of carbonate rocks has benefited from the evolution of ...

Identification of Activity, Insulin, and Dietary Thresholds Associated With Exercise‐Related Hypoglycaemia and Hyperglycaemia in Children With Type 1 Diabetes: A Free‐Living Study Using Explainable Machine Learning

Diabetes, Obesity and Metabolism, EarlyView.
ABSTRACT Aims Some studies have explored associations between physical activity (PA) and hypoglycaemia in real‐life in type 1 diabetes (T1D) but without fully accounting for two major confounders, diet and insulin. We aimed to identify thresholds of PA characteristics, insulin, and carbohydrates associated with dysglycaemia across the exercise‐recovery
