High drafting arrangement for long Cut Staple fibres

The Long Staple Weavable Singles Yarn

Arrangement and density of junctional feet in crayfish muscle fibres.

Junctional feet in tubulo-reticular junctions of crayfish muscle fibres are arranged tetragonally with a centre-to-centre spacing of 30-34 nm. The resulting density of 860-1110 feet per 1 micron 2 of the junctional membrane is similar to that reported for other animal species. Using data of a previous stereological study, there are 150-190 feet per 1 micron 2 of the total T-tubule surface and 6...

Nanoscale arrangement of proteins by single-molecule cut-and-paste.

Protein-based nanostructures are key to the organization of life and it is their precise arrangement, which determines their specific functions. A single-molecule approach for the directed assembly of protein arrangements allows for a controlled composition of systems based on protein components. Applying antibodies and antigenic peptide tags we utilized the Single-Molecule Cut-and-Paste (SMC&P...

Inapproximability Results for Maximum Edge Biclique, Minimum Linear Arrangement, and Sparsest Cut

We consider the Minimum Linear Arrangement problem and the (Uniform) Sparsest Cut problem. So far, these two notorious NP-hard graph problems have resisted all attempts to prove inapproximability results. We show that they have no polynomial time approximation scheme, unless NP-complete problems can be solved in randomized subexponential time. Furthermore, we show that the same techniques can b...
