Perfect hexagon triple systems
This paper gives necessary and sufficient conditions (with only two exceptional cases which remain open) for the existence of perfect maximum packings of \(3kK_n\) with hexagon triples. Here a hexagon triple is a collection of three triples \(abc\), \(cde\), \(efa\) forming a hexagon.

BACK TO BASICS: TOWARDS NOVEL COMPUTATION AND ARRANGEMENT OF SPATIAL SENSORY IN IMAGES
The current camera has made a huge progress in the sensor resolution and the lowluminance performance. However, we are still far from having an optimal camera as powerful as our eye is.

AbstractA hexagon quadrangle system of order n and index ρ [HQSρ(n)] is a pair (X,H), where X is a finite set of n vertices and H is a collection of edge disjoint hexagon quadrangles (called blocks) which partitions the edge set of ρKn, with vertex set X.

This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.

The fundamental group and Galois coverings of hexagonal systems in 3-space
We consider hexagonal systems embedded into the 3-dimensional space ℝ3. We define the fundamental group π1(G) of such a system G and show that in case G is a finite hexagonal system with boundary, then π1(G) is a (non-Abelian) free group.
