'stack of rings' is a correct and usable phrase in written English.
You can use it when referring to a group of rings, usually arranged in some sort of pile or grouping. For example, "The bride wore a stack of rings on each finger."
TIMS consists of a stack of ring electrodes, named the analyzer, whereby each ring is divided into quadrants.
The cell division in the embryo is radial (cells form in stacks of rings directly above each other), holoblastic (cells are separate, although adjoining) and regulative (the type of tissue into which a cell develops is controlled by interactions between adjacent cells, rather than rigidly within each cell).
Complexes of hDmc1 on ssDNA in the presence of ATP and Mg2+ hDmc1 formed stacks of rings on ssDNA template (Figure S2B and C) as described by other groups [14], [18], [31].
In contrast, F-actin rings in the bumblebee formed densely packed nearly contiguous stacks of rings forming a tube of about 1/3 smaller diameter compared to that in the honeybee.
The proteasome is a tube-like structure appearing as a stack of four rings; two outer α-rings and two inner β-rings in order of αββα (Lecker et al, 1999).
The stacking of ring structures is observed for His-69 and Phe-4.
Stacking of ring structures is observed for His-21 and Trp1; Phe-25 and Trp-1; His-18 and Trp-1; His-18 and Phe-5.
Stacking of ring structures is observed for Tyr-99 and Trp-2; Tyr-159 and Trp-2; Trp-2 and Trp- 7 in the peptide; Trp-147 and Trp-5; Trp-133 and Trp-5; Trp-147 and His-6.
Their formation should have invoked both the stacking of ring-like nucleobases and their Watson-Crick pairing.
The quadruple stack of aromatic rings is similar to the stacking observed in the I707L mutant binary crystal structure, except for the n – 1 base pair and the identity of the bases (AA in the crystal structure and GG in the MD simulation).
