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.

Platoon Dispersion Analysis Based on Diffusion Theory

MATEC Web of Conferences, 2017
Urbanization and gro wing demand for travel, causes the traffic system to work ineffectively in most urban areas leadin g to traffic congestion. Many approaches have been adopted to address this problem, one among them being the signal co-ordination ...

A probabilistic framework for modeling chloride‐induced corrosion and related load‐deformation behaviour of reinforced concrete

Structural Concrete, EarlyView.
Abstract Chloride‐exposed reinforced‐concrete structures often suffer localized corrosion, so corrosion initiation time and average steel loss are poor indicators of structural performance. This paper presents a spatially resolved, proof‐of‐concept framework that couples diffusion‐based chloride ingress and initiation with a localized morphology model ...

Closed‐form solutions for dynamic punching shear assessment in flat slabs subjected to sudden column removal

Structural Concrete, EarlyView.
Abstract Simplified closed‐form equations are commonly used in structural design to prevent punching shear failures of concrete flat slabs supported on columns in permanent and transient situations, whereas more advanced methods are generally used in verifications at accidental design situations due to the lack of suitable equivalent approaches ...

Host‐mediated filtering and interspecific associations structure strongyle parasite communities in Sable Island horses

Journal of Animal Ecology, EarlyView.
Using individual‐level nemabiome metabarcoding of 3147 samples from 916 horses on Sable Island over 10 years, we generate the largest dataset of its kind to date. This unprecedented scale enables a rare test of the processes structuring parasite communities in a natural system, revealing dominant host‐mediated filtering and predominantly positive ...

The Value of Controlling Wilding Conifers in New Zealand

Australian Journal of Agricultural and Resource Economics, EarlyView.
ABSTRACT Exotic, invasive conifer tree species, known as ‘wilding conifers’, pose a significant threat to natural ecosystems and are costly to manage, creating a need to identify community preferences in order to inform and balance public investment in their control.

Mainland diversification and recent island lineages in the reduviid genus Tapirocoris: an integrative taxonomic framework with four new species

Insect Science, EarlyView.
Using an integrative taxonomic framework that combines COI DNA barcodes, geometric morphometrics and phylogeography, we revise the assassin bug genus Tapirocoris and recover seven well‐supported species, including four newly described cryptic species.

Intra‐ and Interspecific Effects on Spatio‐Temporal Behavior of Common Commensal Rodent Species

Integrative Zoology, EarlyView.
This study revealed major findings on spatio‐temporal behavior of commensal rodents on a pig farm showing the influence of interspecific dominance on movement behavior and the resulting species‐specific ecological adaptations. Additionally, rodents tend to stay in their home ranges and migration to other stable buildings is only rare.

Fishing Activity Affected Odontocete Cetacean Distribution in a Marine Protected Area in the East China Sea

Integrative Zoology, EarlyView.
Spatiotemporal distribution of odontocete cetaceans within China's Jiushan Archipelago National Nature Reserve was investigated. Fishing vessels significantly reduced both cetacean acoustic detections and feeding activity, whereas gillnets selectively suppressed cetacean feeding behavior without affecting overall cetacean detection rates.
