The number of knots and links with the same 2-fold branched covering
, 2004 We give a nearly complete solution of the problem of how many different knots and links in the 3-sphere, and more generally in homology 3-spheres, can have the same hyperbolic 3-manifold as their common 2-fold branched covering.

Photoreversible Polyurea Actuators With Spatiotemporal Control and Adaptive Mechanics
ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.A light–thermal responsive polyurea network incorporating reversibly dimerizable anthracene units enables spatiotemporal modulation of cross‐linking density and nearly 400‐fold stiffness tuning. Integrating programmable anisotropy, photopatterning, self‐healing, and photowelding within a single framework, this bioinspired “one network–multifunction ...

On grid diagrams, braids and Markov moves
, 2010 Includes abstract.Includes bibliographical references (leaves 42).Grid diagrams are essential in the new combinatorial version [MOST07] of the Heegaard Floer knot homology, and proving that these homologies are actually knot and link invariants depends ...

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.This work fabricated MOF‐based woven absorbing fabrics with dimensional engineering via a wet spinning strategy. The absorbing fabrics achieve a reflection loss of −51.47 dB at 2.9 mm, with an effective absorption bandwidth reaching 3.54 GHz. The absorbing fabrics can be freely bent, stretched, and folded, with individual fibers exhibiting a break ...

Lorenz knots, T–links and twisted torus links
, 2007 A Lorenz knot is the isotopy class of any periodic orbit in the flow on R 3 given by the Lorenz differential equations. By studying them on the Lorenz template, Lorenz knots were shown to include certain known classes, but a complete description remained

Journal of Forecasting, EarlyView.ABSTRACT Sustainability has become an important factor shaping financial markets and investor behavior. This paper examines the relationship between sustainability indices and Central European stock markets using a time–frequency approach. Wavelet coherence is employed to capture time‐varying co‐movements between sustainability indices and stock market

STICK INDEX OF KNOTS AND LINKS IN THE CUBIC LATTICE
, 2012 The cubic lattice stick index of a knot type is the least number of sticks glued end-to-end that are necessary to construct the knot type in the 3-dimensional cubic lattice.
