Optical vortex knots and links via holographic metasurfaces
Advances in Physics: X, 2021 Vortices arise in many natural phenomena as dark points of total destructive interference. Sometimes they form continuous lines and even enclosed loops with knotted or linked topologies in three spatial dimensions.

Creation of electrical knots and observation of DNA topology
New Journal of Physics, 2021 Knots are fascinating topological structures that have been observed in various contexts, ranging from micro-worlds to macro-systems, and are conjectured to play a fundamental role in their respective fields.

HANGING WITHOUT A KNOT: PECULIAR EVENT OR SIMULATED SUICIDE? [PDF]
Euromediterranean Biomedical Journal, 2023 Among the methods of self-harm with suicidal purpose, hanging is the most common; classically, the subject fixes the end of a cable to a support placed at a higher height, on which the traction force given by the weight of the suspended body is applied ...

An influence of abiotic factors on the germinability of Agrostis species and Poa species
Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2006 The objective of this contribution is to interpret the impact of some abiotic factors on the germinability. Primarily was observed the stress that they cause on germinability and also on the energy of other perennial grass caryopsis' germinability ...

Structure of symmetry group of some composite links and some applications
Applied General Topology, 2020 In this paper, we study the symmetry group of a type of composite topological links, such as 22m#22 . We have done a complete analysis on the elements of the symmetric group of this link and show the structure of the group. The results can be generalized
