Development of Prediction Model for Rutting Depth Using Artificial Neural Network

CivilEng, 2023
One of the most common pavement distresses in flexible pavement is rutting, which is mainly caused by heavy wheel load and various other factors. The prediction of rutting depth is important for safe travel and the long-term performance of pavements ...

Remote Language Assessment in School‐Age Children With Phelan–McDermid Syndrome and Genotype–Phenotype Correlation

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT People with Phelan–McDermid syndrome (PMS) have reduced speech and language abilities, yet little research has profiled the communication abilities in this population. The purpose of this study was threefold: identifying the language and communication profiles of school‐aged children with PMS, identifying genetic contributions to language and ...

Serological and histolomorphological investigation of camel bulls testes (Camelus dromedaries) during the rutting and non-rutting seasons

BMC Veterinary Research
Background Camels are bred for their milk, meat, wool and hair, transportation, and their excrement as fuel. The seasonal reproduction of camel bull is accompanied by changes in sexual activity, the morphology, and function of the testes.

Effect of the Field-Stress State on the Subgrade Resilient Modulus for Pavement Rutting and IRI

Geotechnics, 2023
The new Mechanistic-Empirical Pavement Design Guide (MEPDG) uses the subgrade resilient modulus (MR) as the key input parameter to represent the subgrade soil behavior for pavement design.
