Detection of moving objects through turbulent media. Decomposition of Oscillatory vs Non-Oscillatory spatio-temporal vector fields
Jerome Gilles, Francis Alvarez, Nicholas B. Ferrante +4
In this paper, we investigate how moving objects can be detected when images are impacted by atmospheric turbulence. We present a geometric spatio-temporal point of view to the pro…
Threaded Gröbner Bases: a Macaulay2 package
Sonja Petrović, Shahrzad Jamshidi Zelenberg
The complexity of Gröbner computations has inspired many improvements to Buchberger's algorithm over the years. Looking for further insights into the algorithm's performance, we of…
Burton-Cabrera-Frank theory for surfaces with alternating step types
Guangxu Ju, Dongwei Xu, Carol Thompson +5
Burton-Cabrera-Frank (BCF) theory has proven to be a versatile framework to relate surface morphology and dynamics during crystal growth to the underlying mechanisms of adatom diff…
Crystal Truncation Rods from Miscut Surfaces with Alternating Terminations
Guangxu Ju, Dongwei Xu, Carol Thompson +5
Miscut surfaces of layered crystals can exhibit a stair-like sequence of terraces having periodic variation in their atomic structure. For hexagonal close-packed and related crysta…
In Situ Microbeam Surface X-ray Scattering Reveals Alternating Step Kinetics During Crystal Growth
Guangxu Ju, Dongwei Xu, Carol Thompson +5
The stacking sequence of hexagonal close-packed and related crystals typically results in steps on vicinal {0001} surfaces that have alternating A and B structures with different g…
Some algorithms for the mean curvature flow under topological changes
Arthur Bousquet, Yukun Li, Guanqian Wang
This paper considers and proposes some algorithms to compute the mean curvature flow under topological changes. Instead of solving the fully nonlinear partial differential equation…
