Cover Story: In order to transport oxygen, the enzyme, Hemoglobin (Hb), transitions between two allosteric states, T and R. Oxygen binding reapportions rigidity balance in the allosteric transition between the T and R states. Similar functional rigidity changes, which are hallmarks of action at a distance, are found in other allosteric enzymes. View this paper.

The Superconducting Critical Temperature

  • Mike Guidry,
  • Yang Sun and
  • Lian-Ao Wu

20 May 2021

Two principles govern the critical temperature for superconducting transitions: (1) intrinsic strength of the pair coupling and (2) the effect of the many-body environments on the efficiency of that coupling. Most discussions take into account only t...

20 May 2021

A connected graph G is said to be a cactus if any two cycles have at most one vertex in common. The multiplicative sum Zagreb index of a graph G is the product of the sum of the degrees of adjacent vertices in G. In this paper, we introduce several g...
