Cubical coloring -- fractional covering by cuts and semidefinite programming
, 2015 We introduce a new graph invariant that measures fractional covering of a graph by cuts. Besides being interesting in its own right, it is useful for study of homomorphisms and tension-continuous mappings.

Nanoscale Mapping of the Subcellular Glycosylation Landscape
Advanced Science, EarlyView.Using multiplexed super‐resolution imaging with fluorophore‐labeled lectins, this study reports intracellular glycosylation at the nanoscale across organelles and synaptic specializations. Extending glycan analysis beyond the cell surface, Glyco‐STORM reveals distinct glycosylation nanodomains in the ER, Golgi, lysosomes, and synaptic sites.

The chromatic and clique numbers of random scaled sector graphs
Theoretical Computer Science, 2005 In the unit square, \(n\) random points are chosen that are independently and uniformly distributed. At each point a sector is drawn with radius depending on \(n\) and with a fixed angle different from 180 degrees. The directions of the sectors are given by independent uniformly distributed orientation angles.
