From the Capital to the Interior: Urban Planning's Impact on Forests and Landscape Metrics in South Brazil

Land Degradation &Development, EarlyView.
ABSTRACT Urban planning can show deficiencies in implementing infrastructure, especially green infrastructure, resulting in disparities between urban development, environmental quality, and quality of life. However, effective management of green infrastructure and consequently urban forests is crucial for enhancing essential ecosystem services.

Mechanisms of Laser Ablation in Liquids and Their Impact on the Efficiency of Nanoparticle Generation

Laser &Photonics Reviews, EarlyView.
Laser ablation in liquid enables nanoparticle synthesis from diverse materials but remains less energy‐efficient than ablation in air. This study quantifies the absorption‐corrected ablation efficiency and experimentally confirms redeposition as the key loss mechanism using pump‐probe microscopy.

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

Laser &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 ...

Space‐Time FEM Solution of Dynamic Contact Problem With Discontinuous Velocity for Multiple Impact of Deformed Bar Using PDAS Method

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT A class of one‐dimensional impact and dynamic contact problems taking into account non‐smooth velocities is studied. The new space‐time finite element approximation of dynamic variational inequalities is suggested. The non‐smooth solution for the impact of an obstacle by an elastic bar and its energy conservation under persistency conditions ...
