Enhancers and silencers: an integrated and simple model for their function
Epigenetics & Chromatin, 2012 Regulatory DNA elements such as enhancers, silencers and insulators are embedded in metazoan genomes, and they control gene expression during development. Although they fulfil different roles, they share specific properties.

Superconductor–insulator transitions and insulators with localized pairs [PDF]
Physics-Uspekhi, 1998 Two experiments are described which are related to the problem of localized Cooper pairs. Magnetic-field-tuned superconductor-insulator transition was studied in amorphous In--O films with onset of the superconducting transition in zero field near 2 K. Experiments performed in the temperature range T>0.3 K indicate that at the critical field, B=B_c,
