Transmembrane signaling by bacterial chemoreceptors is thought to involve conformational changes within a stable homodimer. We investigated the functional consequences of constraining movement between pairs of helices in the four-helix structure of the transmembrane domain of chemoreceptor Trg. Using a family of cysteine-containing receptors, we identified oxidation treatments for intact cells ...

This study investigated how Mandarin listeners process tone and intonation when the F0 encodings of the lexical tone and intonation are in conflict or in congruency and the role context plays during these processes. Tone and intonation identification experiments were conducted within neutral vs. constraining semantic contexts. Tone identification was much easier than intonation identification i...

As shown in former papers, the nonadiabatic Heisenberg model presents a mechanism of Cooper pair formation generated by the strongly correlated atomic-like motion of the electrons in narrow, roughly half-filled “superconducting bands” of special symmetry. The formation of Cooper pairs is not only the result of an attractive electron–electron interaction but is additionally the outcome of quantu...
