Advanced Healthcare Materials, EarlyView.ABSTRACT Sutures are crucial for tissue approximation and wound healing. Besides their strength limits requirement, they often fail to effectively address complications like infection and pain. Inspired by natural silk's “core‐sheath” structure, our suture features a wet‐spun core of n zinc‐fortified silk fibroin fibers (RSF‐Zn2+) after drawing with ...

Seifert's algorithm, Châtelet bases and the Alexander ideals of classical knots [PDF]
, 2002 I begin by developing a procedure for the construction of a Seifert surface, using Seifert's algorithm, and the calculation of a Seifert matrix for a knot from a suitable encoding of a knot diagram. This procedure deals with the inherent indeterminacy of

Knotting of optical vortices [PDF]
, 2010 Optical vortices form three-dimensional lines of darkness in scalar light. They are places where the phase becomes undefined and hence singular in value.

Satellites and concordance of knots in 3–manifolds [PDF]
, 2018 Given a 3-manifold Y and a free homotopy class in [S-1, Y], we investigate the set of topological concordance classes of knots in Y x [0, 1] representing the given homotopy class. The concordance group of knots in the 3 sphere acts on this set.

Resonant Domain Wall Dynamics in a Three‐Dimensional Magnetic Nano Double Helix
Advanced Materials, EarlyView.3D magnetic nanostructures promise exciting possibilities for magnetization dynamics. However, experimental realizations remain scarce. In nanoprinted cobalt double helices, time‐resolved X‐ray microscopy reveals harmonic domain wall dynamics. Simulations identify the mode and additional higher‐frequency resonances, revealing a rich dynamic landscape ...

Approximating ideal shapes with tight elements [PDF]
, 2005 A variational approach is applied to the problem of finding the shortest curves in space separated by constant distance. Among particular extremal solutions are straight line, circular arc and double helix. Various knots and links may be assembled from

Advanced Robotics Research, EarlyView.This article introduces a soft wearable eyelid sling device incorporating a hydraulic soft artificial muscle (SAM) for achieving complete closure of an eyelid. The SAM is driven by a cam mechanism that provides a displacement profile closely matched with those of a healthy eyelid.

On the number of tubes touching a sphere or a tube [PDF]
, 2006 A problem is formulated about how many unit-radius tubes can toucha ball of given radius from the outside and from the inside. Upper bounds for themaximum numbers of contacts are obtained for both interior and exterior contacts.It is also shown that the ...
