Period and toroidal knot mosaics
, 2017 Knot mosaic theory was introduced by Lomonaco and Kauffman in the paper on `Quantum knots and mosaics' to give a precise and workable definition of quantum knots, intended to represent an actual physical quantum system.

Triple knot of umbilical cord – case report and review of literature
Annales Academiae Medicae Silesiensis, 2023 Multiple true nodes of the umbilical cord are rarely described in literature and refer to patients suffering from pregnancy complications, such as intrauterine growth restriction, or oligohydramnios. We present a case of a 30-year-old woman, admitted for

Non-minimal bridge positions of torus knots are stabilized
, 2010 We show that any non-minimal bridge decomposition of a torus knot is stabilized and that $n$-bridge decompositions of a torus knot are unique for any integer $n$. This implies that a knot in a bridge position is a torus knot if and only if there exists a

Unknotting number and genus of 3-braid knots
, 2013 Let $u(K)$ and $g(K)$ denote the unknotting number and the genus of a knot $K$, respectively. For a 3-braid knot $K$, we show that $u(K)\le g(K)$ holds, and that if $u(K)=g(K)$ then $K$ is either a 2-braid knot, a connected sum of two 2-braid knots, the ...

Simplifying branched covering surface-knots by an addition of 1-handles with chart loops
, 2018 A branched covering surface-knot over an oriented surface-knot $F$ is a surface-knot in the form of a branched covering over $F$. A branched covering surface-knot over $F$ is presented by a graph called a chart on a surface diagram of $F$. For a branched

Dual‐Mode Magnetic Elastomer for On‐Demand Motion and Degradation
Advanced Functional Materials, EarlyView.A dual‐mode magnetic elastomer is introduced, enabling DC field‐driven programmable actuation and AC field‐driven magnetothermal degradation. GHz‐range magnetic fields generate ultrafast heating of magnetic nanoparticles that activates cleavage of the silicone elastomer matrix.
