Involutes of Pseudo-Null Curves in Lorentz–Minkowski 3-Space
Mathematics, 2021 In this paper, we analyze involutes of pseudo-null curves in Lorentz–Minkowski 3-space. Pseudo-null curves are spacelike curves with null principal normals, and their involutes can be defined analogously as for the Euclidean curves, but they exhibit ...

New Directions for Adult and Continuing Education, EarlyView.ABSTRACT Advancing artificial intelligence (AI) has transformed learning and work, yet higher education and professional development programs have not systematically equipped learners for AI‐prevalent environments. This lack of preparation creates uncertainty regarding control, responsibility, trust, and accountability.

Association Between Motor Pathway Damage and Motor Deficit in Upper and Lower Limb in People With MS
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Corticospinal tract damage is common in people with MS, but the degree of clinical symptoms varies. We hypothesize that corticospinal tract lesions are more extensive and severe in people with MS with motor impairments in both upper and lower limbs.

Reconstruction of 3D Curves for Quality Control [PDF]
, 2007 In the area of quality control by vision, the reconstruction of 3D curves is a convenient tool to detect and quantify possible anomalies. Whereas other methods exist that allow us to describe surface elements, the contour approach will prove to be useful to reconstruct the object close to discontinuities, such as holes or edges.

Curve complexes are rigid [PDF]
, 2011 Any quasi-isometry of the curve complex is bounded distance from a simplicial automorphism. As a consequence, the quasi-isometry type of the curve complex determines the homeomorphism type of the ...

Implicit Uniform Rational Spline Reconstruction Method With Regularization Term
IEEE AccessTo improve the accuracy of implicit curve reconstruction and reduce the occurrence of supplementary zero-level sets during the reconstruction process, we propose an implicit curve fitting method with a regularization term based on uniform rational B ...

Atmospheric radiocarbon levels were highly variable during the last deglaciation
Communications Earth & Environment, 2023 Radiocarbon dating provides a key chronological framework for studying past environmental changes. Raw radiocarbon ages measured in samples must be converted to calendar ages using an appropriate calibration curve.

On Calibration and Reconstruction from Planar Curves [PDF]
, 2000 We describe in this paper closed-form solutions to the following problems in multi-view geometry of n'th order curves: (i) recovery of the fundamental matrix from 4 or more conic matches in two views, (ii) recovery of the homography matrix from a single n'th order (n ≥ 3) matching curve and, in turn, recovery of the fundamental matrix from two matching
