Covalent bond symmetry breaking and protein secondary structure
Martin Lundgren, Antti J. Niemi
Both symmetry and organized breaking of symmetry have a pivotal rôle in our understanding of structure and pattern formation in physical systems, including the origin of mass in th…

On universal aspects of the left-handed helix region
Martin Lundgren, Antti J. Niemi, Fan Sha
We inspect the geometry of proteins by identifying their backbones as framed polygons. We find that the left-handed helix region of the Ramachandran map for non-glycyl residues cor…

The Discrete Frenet Frame, Inflection Point Solitons And Curve Visualization with Applications to Folded Proteins
Shuangwei Hu, Martin Lundgren, Antti J. Niemi
We develop a transfer matrix formalism to visualize the framing of discrete piecewise linear curves in three dimensional space. Our approach is based on the concept of an intrinsic…
