Repository contains code and visualizations that demonstrate concepts of scalar and vector fields using the Julia programming language. Explore 3D surface plots and 2D contour plots showcasing scalar ...

Divergence‐measure fields are vector fields whose divergence can be interpreted as a Radon measure rather than a function, thus accommodating cases where the standard smoothness assumptions do ...

We report on the calculation of the total derivative \cx R term in the divergence of vacuum effective action for the nonminimal vector field operator in a curved space background. This term led to an ...

We establish a method for giving lower bounds for the fundamental tone of elliptic operators in divergence form in terms of the divergence of vector fields. We then apply this method to the Lr ...

An ensemble method based on supervised learning for segmenting the retinal vessels in color fundus images is proposed on the basis of previous work of Zhu et al. For each pixel, a 36 dimensional ...
