Refining the timing of Middle Pleistocene (MIS 12 to MIS 6) ice advances into northern central Europe: sedimentological analysis and single‐grain luminescence dating of glaciotectonic complexes and tunnel‐valley fills

open access: yesBoreas, EarlyView.
We summarize the current state of knowledge on the age of the Middle Pleistocene ice advances into northern central Europe and provide 25 new single‐grain feldspar luminescence ages of Elsterian and Saalian glacigenic sediments to constrain the age of the ice advances and their tentative correlation with marine isotope stages/substages.

Droughts and human impact in the ancient Uaymil region of the Maya lowlands inferred from a 2800‐year sedimentary archive at Lake Kaná, Mexico

open access: yesBoreas, EarlyView.
The relationship between the climate and societal transformation in Maya lowlands has long been debated, particularly the role of drought in shaping the civilization trajectory during the Classic Period. A high‐resolution, multi‐proxy, geochemical record from Lake Kaná, located in the underexplored Uaymil region of the Yucatán Peninsula in Mexico ...

Assessment of Different Technologies in the Fabrication of 3D Printed Tooth Models for Dental Education

open access: yesEuropean Journal of Dental Education, EarlyView.
ABSTRACT Background 3D printing has emerged as a practical method for fabricating customisable, accurate and affordable dental training models. Numerous 3D printing technologies exist, though there is no standardised comparison to inform their implementation in dental education.

Network Games With Triadic Interactions

open access: yesInternational Economic Review, EarlyView.
ABSTRACT We propose a model for network‐mediated interactions incorporating higher‐order relationships such as triadic interactions. The marginal utility of an individual's action depends explicitly on endogenous actions of multiple units. Conditions ensuring a unique Nash equilibrium are derived using a variational inequality approach. We estimate the

3D morphological analysis of age and sex‐related changes in human cortical bone remodeling spaces using micro‐CT

open access: yesJournal of Anatomy, EarlyView.
This study investigates human cortical bone remodeling space morphology and its relationship with age and sex using micro‐CT imaging. Remodeling space morphology exhibits great inter‐ and intraindividual variation. Its dimensions decrease with increasing age, but do not differ between sexes.
