Three‐dimensional photogrammetry‐based monitoring to enhance site‐level carbonate budget assessments of coral reefs

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Census‐based carbonate budget assessments synthesize metrics on biologically derived carbonate production and erosion rates to generate estimates of net carbonate production (NCP). ReefBudget is a widely used in‐water carbonate budget approach, but this methodology can be field‐intensive and logistically challenging, limiting spatial data ...

Terahertz All‐Dielectric Maxwell Fisheye Lens Waveguide Crossings via Transformation Optics

open access: yesLaser &Photonics Reviews, EarlyView.
All‐silicon terahertz waveguide crossings based on Maxwell fisheye lenses are reshaped using transformation optics to interface with planar waveguides while reducing mode mismatch. Realized via subwavelength perforations in a single etching step, 2 × 2 and 3 × 3 crossings achieve broadband transmission with low loss and ultralow crosstalk across 220 ...

Age‐Dependent Finite Element Analysis of Microneedle Penetration into Human Skin: Influence of Insertion Velocity, and Microneedle's Geometry and Material

open access: yesMacromolecular Materials and Engineering, EarlyView.
This study evaluates the combined effects of microneedle material, geometry, and insertion velocity on insertion force, considering the critical impact of age‐related variations in human skin. The results show that insertion force increases with age due to higher skin stiffness.
