Application of a self-injection locked cyan laser for Barium ion cooling and spectroscopy [PDF]

, 2020
Compact, high power lasers with narrow linewidth are important tools for the manipulation of quantum systems. We demonstrate a compact, self-injection locked, Fabry-Perot semiconductor laser diode with high output power at 493 nm.

Concrete in architecture: Redefining form, space, function, and insights from bibliometric analysis

Structural Concrete, EarlyView.
Abstract Concrete has become a cornerstone in architectural and engineering innovation, as it seamlessly integrates structural performance with artistic expression. Its evolution from ancient opus caementicium to contemporary ultra‐high‐performance concrete illustrates its adaptability to the change in technological, environmental, and design paradigms.

Tensions in Fostering Student Epistemic Agency Through Sensemaking in Elementary Science

Journal of Research in Science Teaching, EarlyView.
ABSTRACT Recent reforms in science education emphasize engaging students in authentic sensemaking practices. Central to this vision is positioning students as epistemic agents who generate questions, negotiate ideas, and co‐construct scientific understanding. Yet, classroom realities reveal persistent tensions in implementing these ideals, particularly

Dietary and Ranging Behavior of Semi‐Free Ranging Lemur catta and Varecia rubra at Myakka City Lemur Reserve, Florida, USA

Zoo Biology, EarlyView.
Betsiboka, a female red ruffed lemur (Varecia rubra) eating Carolina redroot in the Tower forest. ABSTRACT Lemurs are severely threatened due to anthropogenic habitat loss and climate change. Therefore, understanding how lemurs adapt their diets to novel habitats is critically important for maintaining healthy wild populations and effectively managing ...
