Standardizing Visualization in Ancient Maya Lidar Research: Techniques, Challenges and Recommendations

open access: yesArchaeological Prospection, Volume 32, Issue 4, Page 967-988, October/December 2025.
ABSTRACT Airborne laser scanning (ALS, lidar) has become a key method for studying ancient Maya landscapes, offering unprecedented visibility of anthropogenic terrain modifications in densely forested environments. Despite this progress, the visualization of elevation data remains understandardized, with many researchers relying on ad hoc or ...

Analysis of characteristics of paraxial vector Gaussian beams affecting the formation of microstructures in an azopolymer [PDF]

open access: yesКомпьютерная оптика, 2019
The paper considers paraxial Gaussian laser beams with different polarization states and their characteristics, such as the Poynting vector, gradient force, and force density, which are important for evaluating the effects of radiation on matter.

Describing soil surface microrelief by crossover length and fractal dimension [PDF]

open access: yes, 2007
International audienceAccurate description of soil surface topography is essential because different tillage tools produce different soil surface roughness conditions, which in turn affects many processes across the soil surface boundary.

Biodiversity in mountain soils above the treeline

open access: yesBiological Reviews, Volume 100, Issue 5, Page 1877-1949, October 2025.
ABSTRACT Biological diversity in mountain ecosystems has been increasingly studied over the last decade. This is also the case for mountain soils, but no study to date has provided an overall synthesis of the current state of knowledge. Here we fill this gap with a first global analysis of published research on cryptogams, microorganisms, and fauna in ...
