Dehn surgery on knots in $S^3$ producing Nil Seifert fibred spaces [PDF]
, 2014 We prove that there are exactly $6$ Nil Seifert fibred spaces which can be obtained by Dehn surgeries on non-trefoil knots in $S^3$, with $\{60, 144, 156, 288, 300\}$ as the exact set of all such surgery slopes up to taking the mirror images of the knots.

SPIE Proceedings, 2004 This paper proposes the definition of a quantum knot as a linear superposition of classical knots in three dimensional space. The definition is constructed and examples are discussed. Then the paper details extensions and also limitations of the Aravind Hypothesis for comparing quantum measurement with classical topological measurement.

Bioinspired Soft‐Skeleton Robotics With Cooperative Shape Transformation and Stiffness Adaptation
Advanced Robotics Research, EarlyView.A bioinspired soft‐skeleton robot that integrates variable‐stiffness chain skeletons into a soft textile skin is developed. The chain skeletons are highly flexible initially but can stiffen upon pneumatic actuation, enabling large deformation and enhanced load‐bearing capacity.

fracture toughness; mode I critical stress intensity factor; fracture mechanics; beech wood
Drvna Industrija, 2013 The aim of this research was to examine the content of catechin in normal and traumatic structures of beechwood by high performance liquid chromatography (HPLC). Two discs were sawn from each of six harvested trees.

Statistics of knots, geometry of conformations, and evolution of proteins. [PDF]
PLoS Computational Biology, 2006 Like shoelaces, the backbones of proteins may get entangled and form knots. However, only a few knots in native proteins have been identified so far. To more quantitatively assess the rarity of knots in proteins, we make an explicit comparison between ...

Journal of Graph Theory, 2000 The equivalence classes of graphs induced by the unsigned versions of the Reidemeister moves and delta-wye moves on knot diagrams are considered. Any graph that is reducible to a graph with no edges by some finite sequence of the unsigned version of the Reidemeister graph moves is called a knot graph.
