The size of triangulations supporting a given link [PDF]
, 2000 Let T be a triangulation of S^3 containing a link L in its 1-skeleton. We give an explicit lower bound for the number of tetrahedra of T in terms of the bridge number of L.

2-(5-Bromo-2-methylphenyl)propan-2-ol
Acta Crystallographica Section E, 2010 The title compound, C10H13BrO, crystallizes with four independent molecules of similar geometry in the asymmetric unit. The crystal packing is stabilized by intermolecular O—H...O hydrogen bonds, which link the molecules into tetramers.

Examples of noncommutative manifolds: complex tori and spherical manifolds
, 2007 We survey some aspects of the theory of noncommutative manifolds focusing on the noncommutative analogs of two-dimensional tori and low-dimensional spheres. We are particularly interested in those aspects of the theory that link the differential geometry

Complex surface singularities with integral homology sphere links [PDF]
, 2005 While the topological types of {normal} surface singularities with homology sphere link have been classified, forming a rich class, until recently little was known about the possible analytic structures. We proved in [Geom. Topol.

Homotopy K3's with several symplectic structures
, 2001 In this note we prove that, for any integer n, there exist a smooth 4-manifold, homotopic to a K3 surface, defined by applying the link surgery method of Fintushel-Stern to a certain 2-component graph link, which admits n inequivalent symplectic ...

Reeb orbits and the minimal discrepancy of an isolated singularity [PDF]
, 2015 Let A be an affine variety inside a complex N dimensional vector space which has an isolated singularity at the origin. The intersection of A with a very small sphere turns out to be a contact manifold called the link of A.

Wind Direction Retrieval Using Spaceborne GNSS-R in Nonspecular Geometry
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2020 A wind direction retrieval algorithm using spaceborne global navigation satellite system reflectometry (GNSS-R) in nonspecular geometry is presented. This article first focuses on investigating the influence of wind direction on the scattering strength ...
