Long-Term Monitoring of the Dynamics and Particle Acceleration of Knots in the Jet of Centaurus A
(2010)
We present new and archival multi-frequency radio and X-ray data for Centaurus A obtained over almost 20 years at the Very Large Array and with Chandra, with which we measure the X-ray and radio spectral indices of jet ...
Knotted solutions, from electromagnetism to fluid dynamics
(World Scientific Publ Co Pte Ltd, 2017-11-30)
Knotted solutions to electromagnetism and fluid dynamics are investigated, based on relations we find between the two subjects. We can write fluid dynamics in electromagnetism language, but only on an initial surface, or ...

Aspectos de la teoría de nudos
(2019-09)
Los nudos, tal cual aparecen en nuestra vida cotidiana, son un objeto de estudio en la Matemática. La Teoría de Nudos es la rama de la Matemática que se encarga de su estudio. Un problema central es el de poder decir si ...

Knots can impair protein degradation by ATP-dependent proteases
(National Academy of Sciences, 2017)
ATP-dependent proteases translocate proteins through a narrow pore for their controlled destruction. However, how a protein substrate containing a knotted topology affects this process remains unknown. Here, we characterized ...
Link and knot invariants from non-abelian Yang-Baxter 2-cocycles
(World Scientific, 2016-11)
We define a knot/link invariant using set theoretical solutions (X,σ) of the Yang-Baxter equation and non-commutative 2-cocycles. We also define, for a given (X,σ), a universal group Unc(X) governing all 2-cocycles in X, ...
Lagrangian Formulation, Generalizations and Quantization of Null Maxwell's Knots
(2018-08-01)
Knotted solutions to electromagnetism are investigated as an independent subsector of the theory. We write down a Lagrangian and a Hamiltonian formulation of Bateman's construction for the knotted electromagnetic solutions. ...
