Magnetisation control of the nematicity direction and nodal points in a superconducting doped topological insulator.

We study the effects of magnetisation on the properties of the doped topological insulator of theBi2Se3family with nematic superconductivity. We found that the direction of the in-plane magnetisation fixes the direction of the nematicity in the system. The chiral state is more favourable than the nematic state for large values of out-of-plane magnetisation.

[Isolation and identification of PACE-binding protein rpn4--a new transcription activator, participating in regulation of 26S proteosome and other genes].

A new upstream activating sequence (UAS) 5'-GGTGGCAAA-3' was detected in the promoters of 27 out of the 33 proteasomal genes and of several genes related to the ubiquitin-proteasomal system of Saccharomices cerevisiae. The sequence was termed proteasome-associated control element (PACE). Gel retardation assay revealed specific binding of PACE with an extracted protein.

Uncurved-DNA signals are important for translational positioning of nucleosomes.

We describe here a possible mechanism for non-random arrangement of nucleosomes along genomic DNA by short stretches of uncurved DNA. Available biochemical data on nucleosome positioning on different DNA sequences were analyzed. A strong correlation between location of nucleosome borders and location of uncurved sequences along DNA was observed.
