III. 44-BOND SYSTEM · Inter-strand bonds (17-32): B_inter(k, k+1 mod 16)

Read the equation

This relation defines Inter-strand bonds (17-32): B_inter(k, k+1 mod 16) in the source section “III. 44-BOND SYSTEM · Inter-strand bonds (17-32): B_inter(k, k+1 mod 16)”. Uses a remainder or modular operation, retaining the numeric representation used in the source. Its interpretation depends on the source’s stated variables and conditions; this record does not assign an unprovided physical or cognitive meaning to them.

Terms & definitions

The recovered passage does not supply a separate symbol table. Read the source context for the notation used in this version; familiar letters may carry different meanings in other builds.

How it works

1. Read Inter-strand bonds (17-32): B_inter(k, k+1 mod 16) as the quantity being defined or updated by this relation.

2. Uses a remainder or modular operation, retaining the numeric representation used in the source.

3. Use this version’s variable definitions and update order. The same symbol may be assigned a different meaning in another build.

Assumptions & limits

• This source expression was recovered from the pinned code revision. Its presence does not establish that the associated program was built, run, or scientifically validated.

Original context
