Synchrotron Radiation‐Based Tomography of an Entire Mouse Brain with Sub‐Micron Voxels: Augmenting Interactive Brain Atlases with Terabyte Data

Advanced Science, EarlyView.
Extended‐field acquisition enables sub‐micron X‐ray imaging of a full mouse brain. The 3.3‐teravoxel volume is reconstructed, registered to a reference atlas, and stored in hierarchical format to augment currently available atlases and improve resolution in the third dimension by an order of magnitude.

The role of riparian vegetation flexibility in a bio‐hydro‐morphodynamic simulation

Earth Surface Processes and Landforms, Volume 47, Issue 15, Page 3481-3496, December 2022., 2022
We conducted a bio‐hydro‐morphodynamic simulation to clarify the impact of vegetation flexibility on river bedform development. The figure compares vegetation cover and height during a flooding of channels with flexible (top) and rigid vegetation (bottom). The figure indicates that flexible vegetation reduced its height.

A Novel Dual‐Network Approach for Real‐Time Liveweight Estimation in Precision Livestock Management

Advanced Science, EarlyView.
A novel dual‐network framework is proposed for real‐time, non‐contact liveweight estimation of pigs. By extracting contour information instead of segmented images, the method achieves high accuracy (R2 = 0.993) and an exceptional speed of 1131.6 FPS. This approach enhances automation in livestock farming, providing a scalable and efficient solution for

The use of Van Hiele’s geometric thinking model to interpret Grade 12 learners’ learning difficulties in Euclidean Geometry

Perspectives in Education
The 21st-century mathematics classrooms should equip learners with well-grounded knowledge and thinking skills pertaining to geometry. However, Euclidean geometry remains one of the challenging, if not the most difficult topic for many learners.

Hyperbolic matrix factorization improves prediction of drug-target associations

Scientific Reports, 2023
Past research in computational systems biology has focused more on the development and applications of advanced statistical and numerical optimization techniques and much less on understanding the geometry of the biological space.

Hyperbolic Topological Quantum Sources

Advanced Science, EarlyView.
In this work, we present the experimental realization of hyperbolic topological quantum sources on silicon chips, which only require fewer resources to achieve a higher brightness. It shows a high utilization efficiency and a strong robustness. Abstract Robust Integrable Quantum Optical Sources, Constructed by Topological Boundary States, Are Crucial ...

On the non-generic Tzitzeica-Johnson's Configuration

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2012
Working in the context of Hilbert's axiomatic system, we prove that the Tzitzeica-Johnson configuration has sense in neutral geometry. The elements of a Tzitzeica-Johnson configuration allow us to analyse the Euclidean or the non-Euclidean character of ...

A remark on Chapple-Euler Theorem in non Euclidean geometry [PDF]

arXiv, 2020
In non-Euclidean geometry, there are several known correspondings to Chapple-Euler Theorem. This remark shows that those results yield expressions corredponding to the well-known formula $d=\sqrt{R(R-2r)}$.
