Judging the Intersection of Convex Polygons by Bracket Method [PDF]

open access: yesProceedings of the 2nd International Conference on Computer Application and System Modeling, 2012
In this paper, we study a basic problem based on bracket manipulations in computational geometry: how to judge if two solid convex polygons intersect or not. A key idea in our criteria is that the signs of some brackets of the homogeneous coordinates of the vertices of the two convex bodies are all we need in carrying out the judgment. Experiments show

Comparison of the accuracy of bracket positioning between direct and digital indirect bonding techniques in the maxillary arch: a three-dimensional study

open access: yesProgress in Orthodontics, 2022
Background/objectives When the indirect bonding technique was developed in 1972 by Silverman and Cohen, many authors wondered whether this technique would improve bracket positioning accuracy compared to the direct bonding technique.

Numerical integration methods for the double-bracket flow [PDF]

open access: yesJournal of Computational and Applied Mathematics, 2004
AbstractIn this paper new methods up to order four based on the Magnus expansion are proposed for the numerical integration of the double-bracket equation. The Magnus series is constructed term-by-term by means of recurrences and a bound on the convergence domain is also provided.

occumb: An R package for site occupancy modeling of eDNA metabarcoding data

open access: yesPopulation Ecology, EarlyView.
This study introduces a new R package, occumb, for the convenient application of site occupancy modeling using environmental DNA (eDNA) metabarcoding data. We outline a data analysis workflow, including data setup, model fitting, model assessment, and comparison of potential study settings based on model predictions, all of which can be performed using
