Veterinary Dermatology, Volume 31, Issue 6, Page 471-e126, December 2020., 2020 Background – Equine sarcoids are the most prevalent skin neoplasm in horses worldwide. Although several treatments are available, none are consistently effective and recurrence is common. Objectives – To evaluate the efficacy and safety of topical imiquimod 5% cream and Sanguinaria canadensis + zinc chloride for treatment of equine sarcoids and ...

Engel groups and universal surgery models
Journal of Topology, Volume 13, Issue 3, Page 1302-1316, September 2020., 2020 Abstract We introduce a collection of 12‐π1‐null four‐dimensional surgery problems. This is an intermediate notion between the classically studied universal surgery models and the π1‐null kernels which are known to admit a solution in the topological category.

Untwisting 3‐strand torus knots
Bulletin of the London Mathematical Society, Volume 52, Issue 3, Page 429-436, June 2020., 2020 Abstract We prove that the signature bound for the topological 4‐genus of 3‐strand torus knots is sharp, using McCoy's twisting method. We also show that the bound is off by at most 1 for 4‐strand and 6‐strand torus knots, and improve the upper bound on the asymptotic ratio between the topological 4‐genus and the Seifert genus of torus knots from 2/3 ...

DNA Knotting in Spooling Like Conformations in Bacteriophages
Computational and Mathematical Methods in Medicine, Volume 9, Issue 3-4, Page 303-316, 2008., 2008 A number of idealized models have been proposed to explain the long range organization of the DNA in bacteriophages. However, none of these models can account for the distributions of complex knots found when examining DNA extracted from bacteriophage P4 capsids.

Skein modules of links in cylinders over surfaces
International Journal of Mathematics and Mathematical Sciences, Volume 32, Issue 9, Page 515-554, 2002., 2002 We define the Conway skein module 𝒞 (M) of ordered based links in a 3‐manifold M. This module gives rise to 𝒞 (M)‐valued invariants of usual links in M. We determine a basis of the ℤ[z]‐module 𝒞 (Σ × [0, 1])/Tor (𝒞 (Σ × [0, 1])), where Σ is the real projective plane or a surface with boundary. For cylinders over the Möbius strip or the projective plane,

Modeling repulsive forces on fibres via knot energies
Computational and Mathematical Biophysics, 2014 Modeling of repulsive forces is essential to the understanding of certain bio-physical processes, especially for the motion of DNA molecules. These kinds of phenomena seem to be driven by some sort of “energy” which especially prevents the molecules from

HEEGAARD FLOER HOMOLOGY AND RATIONAL CUSPIDAL CURVES
Forum of Mathematics, Sigma, 2014 We apply the methods of Heegaard Floer homology to identify topological properties of complex curves in $\mathbb{C}P^{2}$. As one application, we resolve an open conjecture that constrains the Alexander polynomial of the ...

About some infinite family of 2‐bridge knots and 3‐manifolds
International Journal of Mathematics and Mathematical Sciences, Volume 24, Issue 2, Page 95-108, 2000., 2000 We construct an infinite family of 3‐manifolds and show that these manifolds have cyclically presented fundamental groups and are cyclic branched coverings of the 3‐sphere branched over the 2‐bridge knots (ℓ + 1) 2 or (ℓ + 1) 1, that are the closure of the rational (2ℓ − 1)/(ℓ − 1)‐tangles or (2ℓ − 1)/ℓ‐tangles, respectively.

The classification of partially symmetric 3-braid links
Open Mathematics, 2015 We classify 3-braid links which are amphicheiral as unoriented links, including a new proof of Birman- Menasco’s result for the (orientedly) amphicheiral 3-braid links. Then we classify the partially invertible 3-braid links.

Characteristic polynomials of some weighted graph bundles and its application to links
International Journal of Mathematics and Mathematical Sciences, Volume 17, Issue 3, Page 503-510, 1994., 1994 In this paper, we introduce weighted graph bundles and study their characteristic polynomial. In particular, we show that the characteristic polynomial of a weighted ‐bundles over a weighted graph G? can be expressed as a product of characteristic polynomials two weighted graphs whose underlying graphs are G As an application, we compute the signature ...
