Perception of Clinical Learning Experience: Dental Student Voices

European Journal of Dental Education, Volume 29, Issue 2, Page 427-432, May 2025.
ABSTRACT Introduction This study sought to explore dental students' perceptions of their clinical learning experience through the use of similes and metaphors in order to provide useful insights for clinical teaching. Materials and Methods 69 dental students in their clinical years (4th, 5th and 6th) participated in this study by responding to an ...

Detection of Low‐Altitude Cislunar Dust With the Lunar Occultation Archive

Geophysical Research Letters, Volume 52, Issue 8, 28 April 2025.
Abstract It is believed that dust formations above the lunar surface, manifested via sunlight scattering and detected in‐situ, are of too low density to pose threats to lunar missions. However, occasionally prolonged fading/kindling of the immersing/emerging stars near the lunar limb indicates much denser low‐altitude dust clouds.

Interpreting Turbulence Anisotropy in a Streamline Coordinate System

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 8, 28 April 2025.
Abstract Mixing and transport in the atmospheric boundary layer are a result of the anisotropic nature of turbulence. Recently the inclusion of anisotropy of the Reynolds stress tensor into similarity theory of near‐surface turbulence has been proposed.

Efficiency of Thermoremanent Magnetization Acquisition in Vortex‐State Particle Assemblies

Geophysical Research Letters, Volume 52, Issue 8, 28 April 2025.
Abstract Magmatic rocks record ambient magnetic fields during cooling, preserving them for billions of years through thermoremanent magnetization (TRM). TRM accuracy depends on particle size, shape, magnetic properties, and the number of particles available to record the field.

Diachronous Accumulation of Mid‐Pleistocene Gravel Beds Driven by Tectonics Across the Tibetan Plateau

Geophysical Research Letters, Volume 52, Issue 7, 16 April 2025.
Abstract Deciphering how the widespread late Cenozoic conglomerates were formed across the Tibetan Plateau is crucial for understanding the competition between tectonics and climate. Here we target the mid‐Pleistocene conglomerate cap along the northern Saishiteng range (SR), North Tibet. 26Al/10Be burial dating constrains the onset accumulation of the
