Exploring the potential of Textile Reinforced Concrete for corrosion‐insensitive retaining walls

Structural Concrete, EarlyView.
Abstract In a context where durability concerns, particularly the corrosion of steel reinforcement, remain a critical challenge for conventional reinforced concrete structures under severe exposure, Textile Reinforced Concrete (TRC) is emerging as a promising alternative.

Analysis of the mechanism and effects of advanced pipes support in roadways

Scientific Reports
With the increasing depth of coal mining, the deformation and instability of high-stress soft rock roadways have become critical challenges in mining engineering. Although various support technologies have been applied to deep soft rock roadways, research on the support mechanism and mechanical effects of advanced pipes remains limited.

Deflection‐based assessment of residual prestress in simply‐supported bridges accounting for creep variability

Structural Concrete, EarlyView.
Abstract Several test methods have been proposed in the literature for measuring the level of residual prestress, most of them involving either semi‐ or fully destructive techniques for local measurements which could be highly sensitive to boundary conditions and execution details.

Research on the dynamic pressure influence and support engineering strategy of roadway group under multi section collaborative mining conditions

Scientific Reports
Multiple roadways have been excavated to form an underground production system, which is used for multi section collaborative mining of room pillar structures, achieving efficient mining of underground inclined and steeply inclined ore bodies; however ...

Experiment and Application of Coalcrete on Roadway Stability: A Comparative Analysis

Advances in Materials Science and Engineering, 2020
Improving roadway stability in deep underground mines is quite challenging, as the conventional support structures easily fail. Roadway collapse and large deformation occur just several months after tunnel excavation.

Looking for Trouble: Pre‐Intervention Monitoring in Human and AI Driver Training

Symbolic Interaction, EarlyView.
We compare two types of situations involving monitoring of car driving: a driving instructor overseeing a trainee driver and a safety driver overseeing the performance of autonomous vehicle (AV) software. Our focus is on instances of monitoring that precede (1) interventions that are aborted before impacting the driving and (2) actual interventions on ...

Differences in mammal community response to highway construction across different levels of human land use

Wildlife Biology, EarlyView.
Worldwide, transportation agencies have been involved in road mitigation efforts to reduce road mortality and promote connectivity of endangered species. Baseline data on how mammals respond to highway construction, however, are rarely collected in road mitigation and monitoring studies, including in the USA.

Monitoring the effects of ovariectomy on seasonal movement behavior in suburban female white‐tailed deer using internet of things‐enabled devices

Wildlife Biology, EarlyView.
Abundant deer populations often cause conflicts in suburban communities, yet traditional population reduction methods, such as controlled hunting, can be challenging to implement. Fertility control, specifically through ovariectomy, can limit reproduction and reduce populations in certain settings, but its effect on movement behavior remains poorly ...

Availability bias and responsive movement during ground‐based wildlife surveys revealed by concurrent thermal drone surveys

Wildlife Biology, EarlyView.
Methods to estimate abundance from unmarked populations of animals are widely used because of their efficiency and presumed accuracy. These methods account for imperfect detection by comparing observed data against the assumed distribution of the entire population.
