Three-dimensional imaging of subepithelial tumors: feasibility and utility in preoperative assessment—a retrospective single-center observational study in Japan [PDF]

open access: yesClinical Endoscopy
Background/Aims Endoscopic ultrasound and conventional computed tomography (CT) are useful for preoperative assessment of subepithelial tumors (SETs). However, surgical approaches are sometimes changed intraoperatively owing to unexpected discrepancies ...

Evaluating Sand Particle Surface Smoothness Using a New Computer-Based Approach to Improve the Characterization of Macroscale Parameters

open access: yesGeotechnics, 2023
The analysis of sands, and the foundation systems with which they interact, are largely dependent on macroscale behavioral parameters that represent the aggregated response of several microscale characteristics. This research paper examines the influence

The relationship between shape and size of diaspores depends on being seeds or fruits [PDF]

open access: yes, 2019
The relationship between the size and shape of diaspores was investigated in angiosperms and gymnosperms including determining if being a seed or fruit was a factor. Size was expressed as volume and shape as the departure from a perfect idealized sphere.
