Theory of chiral order in random copolymers.
Recent experiments have found that polyisocyanates composed of a mixture of opposite enantiomers follow a chiral “majority rule:” the chiral order of the copolymer, measured by optical activity, is dominated by whichever enantiomer is in the majority. We explain this majority rule theoretically by mapping the random copolymer onto the random-field Ising model. Using this model, we predict the c...
متن کاملRandom hydrophilic-hydrophobic copolymers
We study a single statistical amphiphilic copolymer chain AB in a selective solvent (e.g. water). Two situations are considered. In the annealed case, hydrophilic (A) and hydrophobic (B) monomers are at local chemical equilibrium and both the fraction of A monomers and their location along the chain can vary, whereas in the quenched case (which is relevant to proteins), the chemical sequence al...
متن کاملBringing Order to the Separation Logic Jungle
Research results from so-called “classical” separation logics are not easily ported to so-called “intuitionistic” separation logics, and vice versa. Basic questions like, “Can the frame rule be proved independently of whether the programming language is garbage-collected?” “Can amortized resource analysis be ported from one separation logic to another?” should be straightforward. But they are n...
متن کاملBringing order to early B cell chaos
In the early 1990s, Richard (Randy) Hardy and colleagues divided B cell precursors into subpopulations--the Hardy fractions--based on the cells' expression of various cell surface proteins. This classification helped lay the groundwork for our present-day understanding of the molecular events that control early B cell development.
متن کاملFluctuation Theory of Random Copolymers
We investigate trie behavior of symmetric AB random copolymer melt near trie point of microphase separation in trie framework of a one-trop (Hartree-Fock) approximation, that exactly salves trie problem. We bave shown that composition fluctuations result to complete elimination of trie microphase separation predicted in trie frarnework a mean-field approximation [1-5]. Using variational techniq...
