Permanent deformation modelling of large-size unbound pavement materials tested in a heavy vehicle simulator under different moisture conditions

, 2022
Climate changes alter the environmental conditions which pavement design is based on, invalidating empirical design methods. Transition to mechanistic design requires the ability to model the behaviour of pavement materials under relevant environmental ...

Evaluation of Performance and Challenges of Use of Waste Materials in Pavement Construction: A Critical Review

Applied Sciences, 2019
Paved surfaces must reliably bear heavy loads, often under challenging environmental and geotechnical conditions. These requirements are addressed through the use of high-quality, newly produced materials in pavement design. However, in remote locations,

A Prospective Study of Individuals at Risk of Multiple Sclerosis Informs the Design of Primary Prevention Studies

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective In multiple sclerosis, the optimal time for deploying a therapeutic intervention is before the central nervous system is damaged; given the success of trials treating the earliest stage of MS, the radiologically isolated syndrome, developing primary prevention strategies is an important next challenge.

RNA Sequencing Resolves Cryptic Pathogenic Variants in Mitochondrial Disease

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Mitochondrial diseases are the most common inherited metabolic disorders, characterized by pronounced clinical and genetic heterogeneity that complicates molecular diagnosis. Although DNA‐based sequencing approaches have become standard in genetic testing, up to half of patients remain without a definitive diagnosis.

Simultaneous analysis of structural reliability and parameter sensitivity of flexible pavements

Case Studies in Construction Materials
To account for the influence of uncertainties in pavement design, adopting a probabilistic limit state-based approach for asphalt pavement structural design is currently the prevailing solution. However, due to the numerous parameters involved in asphalt
