COPIS: A robust and versatile robotic imaging system for the 3D digitization of natural history specimens with photogrammetry

Methods in Ecology and Evolution, Volume 17, Issue 5, Page 1617-1627, May 2026.
Abstract Ecologists and evolutionary biologists are increasingly turning to 3D models to use in scientific research. Natural history museums are one of the primary sources for specimens used as 3D models, and efforts are underway to digitize their collections using methods like photogrammetry.

Stemflow Dynamics in the Jamari National Forest (Brazilian Amazon): I. The Role of Tree Structure

Biotropica, Volume 58, Issue 3, May 2026.
A portion of rainfall that contacts tree canopies is drained down tree stems as stemflow. Stemflow is an underexamined component of rainfall partitioning in tropical forests. To investigate how tree canopy structural attributes influence stemflow in the Brazilian Amazon, we measured stemflow, rainfall, and dendrometric parameters of 56 trees in the ...

Integrative Computational and Experimental Approaches Reveal the Protective Role of Moderate Caffeine Intake Against Apical Periodontitis Induced Bone Loss

International Endodontic Journal, Volume 59, Issue 5, Page 873-889, May 2026.
ABSTRACT Aim To investigate whether moderate systemic caffeine intake modulates the progression of apical periodontitis (AP) and associated alveolar bone loss, combining in vivo rat experiments with in silico molecular docking to explore potential mechanisms. Methodology Male Wistar rats were randomly assigned to four groups (n = 8 per group): control,

Space and camera path reconstruction for omni-directional vision

, 2007
In this paper, we address the inverse problem of reconstructing a scene as well as the camera motion from the image sequence taken by an omni-directional camera.

Turning Mediterranean Farmlands Into Priority Habitats: Natural Expansion of Juniper Woodlands After Agricultural Abandonment

Journal of Vegetation Science, Volume 37, Issue 3, May/June 2026.
Spanish juniper woodlands are expanding across central Spain as farmland is abandoned. By combining 34 years of land‐cover data with high‐resolution photogrammetry and field measurements, we show that juniper growth depends on topography, solar exposure and competition with shrubs. High irradiance increases biomass in older stands but limits young ones,

Refraction-Aware Structure from Motion for Airborne Bathymetry

Remote Sensing
In this work, we introduce the first pipeline that combines a refraction-aware structure from motion (SfM) method with a deep learning model specifically designed for airborne bathymetry. We accurately estimate the 3D positions of the submerged points by
