Abstract: A circularly polarized transmitarray antenna is proposed based on the unit cell composed of a magneto-electric dipole and a helical structure. The receiving unit and transmitting unit are ...

Fe–S clusters are among the most conserved cofactors in prokaryotes and eukaryotes. Fe–S proteins participate in a wide array of cellular processes, from metabolism to gene regulation and DNA ...

Intermediate filaments (IFs) are assembled from fibrous proteins that exhibit a central α-helical rod domain with a conserved substructure. This rod domain facilitates the formation of dimeric ...
