The number |K| of non-isotopic framed knots that correspond to a given unframed knot K âŠ‚ S is infinite. This follows from the existence of the self-linking number slk of a zerohomologous framed knot.â€¦ (More)

BACKGROUND
The aim of our study was to determine if ablation and pacing improved brain perfusion (BP) and cognitive function (CF) in patients with medically refractory rapidly conducted atrialâ€¦ (More)

For a fixed isotopy type K of unframed knots in S there are infinitely many isotopy classes of framed knots that correspond to K when we forget the framing. We show that the same fact is true for allâ€¦ (More)

Let (X m+1 , g) be a globally hyperbolic spacetime with Cauchy surface diffeo-morphic to an open subset of R m. The Legendrian Low conjecture formulated by NatÃ¡rio and Tod says that two events x, y âˆˆâ€¦ (More)

24,564 autopsy protocols from the central city hospital and oncology dispensary were analyzed in order to evaluate the rate and dynamics of postoperative thrombotic complications (PTC). The PTC rateâ€¦ (More)

It is well-known that a knot in a contact manifold (M, C) transverse to a trivialized contact structure possesses the natural framing given by the first of the trivialization vectors along the knot.â€¦ (More)
