Pulsed electron double resonance (PELDOR) spectroscopy reveals a prearranged tertiary structure of the 27 nucleotides long engineered neomycin-responsive riboswitch. Measured distances between spin ...

Nicotinic acetylcholine (ACh) receptors and other Cys-loop receptors challenge our ability to understand how proteins carry out simple sets of functions — in this case, specific binding ...

A ±45° dual-polarized concentrically arranged dipole antenna is proposed for base station applications. The simple, robust antenna consists of four simple dipoles arranged in a square above a flat ...
