Matched Queries for Curvature and Density at Branching Junctions
Ziqi Zhao, Qingjian Ni
At a junction, a score field can reveal weighted tangent rays, yet these first-order quantities do not determine how individual branches bend or how their densities change away fro…

Recovering Weighted Tangent Geometry from a Single-Scale Score Field
Ziqi Zhao, Qingjian Ni
Near a smooth data manifold, one tangent space summarizes local geometry. At a branch point, the corresponding first-order object is instead a measure over tangent directions, whos…

When More Generators Hurt: Shellsort on Full Product Grids
Ziqi Zhao, Qingjian Ni
Shellsort repeatedly runs insertion sort with decreasing gaps, so its worst-case cost depends on the gap sequence. Pratt's sequence, one of the few systematic construction…
