Sine-Cosine Optimization-Based Bijective Substitution-Boxes Construction Using Enhanced Dynamics of Chaotic Map

Complexity, 2018
This paper proposes a novel method of constructing strong substitution-boxes (S-boxes) of order n (4 ≤ n ≤ 8) based on a recent optimization algorithm known as sine-cosine algorithm (SCA). The paper also proposes a new 1D chaotic map, which owns enhanced

Endocytosis‐independent cytosolic entry of messenger RNA via fluorous bilayer zippering attenuating Toll‐like receptor signaling and enables ischemic tissue salvage

Smart Molecules, EarlyView.
The present study establishes a paradigm shift in synthetic mRNA delivery through the convergence of three orthogonal chemistries—perfluoro‐acylation, bio‐orthogonal click cross‐linking, and disulfide reduction—within a single, modular polymer architecture. Abstract A fundamental constraint of conventional messenger RNA (mRNA) delivery systems is their
