Bending of DNA induced by M.Msp I, one of the m5C-DNA methyltransferases, has been investigated using circular permutation analysis. The M.Msp I MTase induced sharp bends in DNA containing its recognition sequence 5'-CCGG-3'which was estimated to be 142+/-4 degrees and 132+/-4 degrees for circularly permuted DNA fragments of 127 and 1459 bp respectively. The bend centre was found to be asymmetr...

Synchrotron particle accelerators are mainly composed of magnets. Long dipole magnets are employed to bend and to contain the beam within a circular trajectory. Their field quality is usually tested by arrays of rotating coils. Typically the measurements must be affected by low uncertainty (+10) and the calibration of the sensing coils, in terms of surface and angle, is critical. In this paper,...

Sharing topology with numerous organic molecules, a wire helix bend into a torus gives a curious object with a gyrotropic behavior which is far from obvious. While a continuous constant current in opposite sections of the torus would create mutually cancelling contributions to its gyrotropic response, an array of tori can show strong circular dichroism linked to the excitation of standing curre...

Self-organized wrinkling patterns of a liquid crystalline polymer, dictated by the chemico-physically anisotropic nature of surface wettability, are demonstrated in confined geometries. The symmetry of the geometrical constraints of the confinement primarily governs the periodic wrinkling patterns of such a polymer in the wetting region. In a circular geometry, the number of the radial domains ...

We study a fully developed creeping flow of nematic liquid crystals in curved pipe with circular cross-section. A special limit zero Deborah number and an infinite Ericksen is considered, so the orientation director are described by transversely isotropic fluid (TIF) model. Analytical solutions obtained expanding governing equation small curvature ?, defined as ratio radius to bend. show that p...
