MeshNav3D: Software for Visualizing and Benchmarking Uneven Terrain Planning Algorithms

Journal of Open Research Software
MeshNav3D is a Python-based framework that addresses the lack of reproducible, standardized benchmarking tools for motion planning on uneven 3D terrain represented as triangle meshes. It supports common mesh formats (.obj, .ply) and integrates a range of

Variationality of Conformal Geodesics in dimension 3: Variationality of Conformal Geodesics in dimension 3 [PDF]

Conformal geodesics form an invariantly defined family of unparametrized curves in a conformal manifold generalizing unparametrized geodesics/paths of projective connections.

3D Reconstruction of Nanoparticle Distribution in Tumor Spheroids With Volume Electron Microscopy

Small, EarlyView.
Understanding where nanomaterials accumulate within cells is essential for revealing their biological fate and activity. We present a quantitative imaging framework to map nanomaterials and cellular structures in three dimensions. Applied to nanoparticle‐containing tumor spheroids, the approach reveals substantial cell‐to‐cell differences in uptake ...

Geometric Linearization of Ordinary Differential Equations

Symmetry, Integrability and Geometry: Methods and Applications, 2007
The linearizability of differential equations was first considered by Lie for scalar second order semi-linear ordinary differential equations. Since then there has been considerable work done on the algebraic classification of linearizable equations and ...

Inscribing geodesic circles on the face of the superstratum

Journal of High Energy Physics
We use families of circular null geodesics as probes of a family of microstate geometries, known as (1, 0, n) superstrata. These geometries carry a left-moving momentum wave and the behavior of some of the geodesic probes is very sensitive to this ...

Influence of natural fibers on physical, mechanical, and fire‐resistant properties of microconcrete

Structural Concrete, EarlyView.
Abstract This study examined the influence of natural fibers on the physical, mechanical, and fire‐resistant properties of microconcrete, in comparison with conventional polypropylene fibers used in cement composites. The fibers were characterized by FTIR and TGA/DSC to assess their composition and thermal stability, and FTIR was also performed after ...

Take Me Home, Country Roads: Choosing Autonomous EVs Over Personal Aviation

Australian Journal of Agricultural and Resource Economics, EarlyView.
ABSTRACT This paper investigates the potential long‐run effects of autonomous and electric vehicles, and a carbon tax, on personal domestic aviation demand in Australia. We estimate a discrete choice disutility model with two travel modes—car and air—using Australian National Visitor Survey data and Bayesian priors. We use multiplicative Fréchet errors,

ABSTRACT The Video “Geodesics and Waves”

, 2008
The video Geodesics and Waves introduces the concepts of straightest geodesics and geodesic flow on polyhedral surfaces. It is the third in a series of videos presenting research results from the area of mathematics and visualization produced at ...

Lost in Aggregation: Quantifying Measurement Error from Geographic Centroids

Economic Record, EarlyView.
Due to privacy laws and regulations, microdata typically provide regional identifiers rather than exact coordinates. Researchers therefore often construct spatial variables from these aggregations, but the statistical implications depend on the research setting.
