Bridging the Late Antique Gap in Northwest Arabia: New Archaeological Evidence on the Occupation of Wādī al‐Qurā (al‐ʿUlā [AlUla], Saudi Arabia) Between the Third and Seventh Centuries CE

Arabian Archaeology and Epigraphy, EarlyView.
ABSTRACT In 2019, the Dadan Archaeological Project (CNRS/RCU/AFALULA) identified a Late Antique village 1 km south of ancient Dadan in the al‐ʿUlā valley (northwest Saudi Arabia). Three excavation seasons at this site (2021–2023) have uncovered a massive building constructed in the late third or early fourth cent.

The Recruitment and Retention of Individuals With Intellectual Disability in Randomized Controlled Trials: A Scoping Review

British Journal of Learning Disabilities, EarlyView.
ABSTRACT Background People with intellectual disabilities face significant health disparities and often encounter barriers in accessing healthcare services. Although research supports the need for reasonable adjustments to improve healthcare access for this population, implementation in acute healthcare settings remains limited.

Red era: Dyeing yak hair fibres red with in situ generated silver nanoparticles using silver nitrate and a flavonoid‐containing plant extract

Coloration Technology, EarlyView.
Abstract Plants and their extracts have been used for dyeing fabrics, skin and hair for thousands of years and have been experiencing a revival in the last years due to increasing health risks arising from oxidative hair dye precursors. We developed a novel two‐step method to dye keratin fibres based on in situ formed silver nanoparticles including a ...

Spontaneously formed phonon frequency combs in van der Waals solid CrGeTe3 and CrSiTe3

Nature Communications
Optical phonon engineering through nonlinear effects has been utilized in ultrafast control of material properties. However, nonlinear optical phonons typically exhibit rapid decay due to strong mode-mode couplings, limiting their effectiveness in ...
