Implant‑position reproducibility of wired and wireless intraoral scanners and the effects of Wi‑Fi distance and upload speed: an in vitro study [PDF]
BMC Oral HealthBackground The impact of wireless communication on intraoral scanning reproducibility remains unclear. This in‑vitro study aimed to compare the implant‑position reproducibility of wireless (Wi‑Fi) and wired intraoral scanners using a mandibular ...

Classical knot and link concordance
Commentarii Mathematici Helvetici, 1993 In an earlier paper, the author combined the knot concordance invariants of Levine with those of Casson-Gordon by considering the homology of the 2-fold branched cyclic cover. This approach is generalized in the present paper by simultaneously considering all the \(q\)-fold branched cyclic covers for \(q\) a prime power.

Link concordance and algebraic closure, II
Inventiones Mathematicae, 1989 This is the sequel to Part I reviewed above (see Zbl 0692.57009). The author defines a group G to be algebraically closed (AC) if each finite system of equations \(x_ i=w_ i\in G*F(x_ 1,...,x_ n)\), where each \(w_ i\) is a product of conjugates of elements of G, has a unique solution in G.

Link concordance invariants and homotopy theory
Inventiones Mathematicae, 1987 This paper is concerned with the link invariants defined by K. Orr for codimension two links in the \((n+2)\)-sphere. It is shown here that for spherical links almost all of these invariants vanish if \(n>1\), and that for \(n=1\) they are zero if and only if Milnor's \({\bar \mu}\)-invariants vanish (a result which the author points out was obtained ...

The Casson-Gordon invariant and link concordance
Topology, 1992 A theory of Casson-Gordon invariants for smooth links in \(S^{2n + 1}\), \(n \geq 1\), is developed. First the invariant \(\tau\) is defined for a knot \(S^{2n-1}\) in \(S^{2n + 1}\) using \(q\)-fold covers, \(q\) a prime power. This is applied to a certain family of links which are shown to be not concordant to boundary links.

Link concordance invariants and Massey products
Topology, 1991 Let \({\mathcal L}=(K,L)\) be a codimension-2 link in \(S^ n\), i.e. \(K\) and \(L\) are disjoint oriented \((n-2)\)-dimensional submanifolds of the \(n\)- sphere, \(n\geq 3\). If \({\mathcal L}\) is ``\(j\)-admissible'' (i.e. under certain assumptions related to the intersection behaviour of Seifert surfaces) the author defines \(j\) link concordance ...

Links not concordant to the Hopf link [PDF]
Mathematical Proceedings of the Cambridge Philosophical Society, 2014 AbstractWe give new Casson–Gordon style obstructions for a two–component link to be topologically concordant to the Hopf link.
