Differential geometry of polymer models: worm-like chains, ribbons and Fourier knots [PDF]
Journal of Physics A: Mathematical and Theoretical, 2007 We analyze several continuum models of polymers: worm-like chains, ribbons and Fourier knots. We show that the torsion of worm-like chains diverges and conclude that such chains can not be described by the Frenet-Serret (FS) equation of space curves.

Conformational Statistics of Ribbon-like Chains
, 2023 The chemistry of conjugated polymers and ladder polymers endows them with anisotropic bending stiffnesses in their backbones, giving rise to “ribbon-like” structures that the existing statistical polymer models do not fully capture.

Toxins, 2019 Most ribbon worms (phylum: Nemertea) are found in marine environments, where they act as predators and scavengers. They are characterized by an eversible proboscis that is used to hunt for prey and thick mucus covering their skin.

Identification of RAG-like transposons in protostomes suggests their ancient bilaterian origin
Mobile DNA, 2020 Background V(D) J recombination is essential for adaptive immunity in jawed vertebrates and is initiated by the RAG1-RAG2 endonuclease. The RAG1 and RAG2 genes are thought to have evolved from a RAGL (RAG-like) transposon containing convergently-oriented

Sediment Variation and Occurrence of Milky Ribbon Worm (Cerebratulus lacteus) in the Gulf of Maine
, 2022 Average seawater temperatures have been steadily increasing for the past four decades, creating drastic ecosystem shifts for many aquatic species. Commercial landings of softshell clams across the state have decreased by almost 75%, as a result high ...
