Interaction, bond formation or reaction between a dimethylamino group and an adjacent alkene or aldehyde group in aromatic systems controlled by remote molecular constraints

A NUMERICAL RENORMALIZATION GROUP APPROACH FOR AN ELECTRON-PHONON INTERACTION

A finite chain calculation in terms of Hubbard X-operators is explored by setting up a vibronic Harniltonian. The model conveniently transformed into a form so that in the case of strong coupling a numerical renormalization group approach is applicable. To test the technique, a one particle Green function is calculated for the model Harniltonian

Divisible Designs Admitting, as an Automorphism Group, an Orthogonal Group Or a Unitary Group

Insight into the reaction between a primary amine and a cavitand with an introverted aldehyde group: an enzyme-like mechanism.

Density functional theory investigations reveal that a cavitand with an introverted aldehyde group not only provides the host-guest interaction for preorganizing the substrate and stabilizing the hemiaminal intermediate, but also acts as an acid/base catalyst in the subsequent dehydration step in its reaction with a primary amine.

Group Formation with Network Constraints

In this paper, I illustrate the importance of both dynamics and network constraints in the group formation process. I introduce a class of games called sequential group formation games, in which players make their group membership decisions sequentially over time, and show that the dynamics act as an equilibrium refinement. However, the resulting equilibrium is highly suboptimal–groups tend to ...

Immobilization of DNA via oligonucleotides containing an aldehyde or carboxylic acid group at the 5' terminus.

A general method for the immobilization of DNA through its 5'-end has been developed. A synthetic oligonucleotide, modified at its 5'-end with an aldehyde or carboxylic acid, was attached to latex microspheres containing hydrazide residues. Using T4 polynucleotide ligase and an oligonucleotide splint, a single stranded 98mer was efficiently joined to the immobilized synthetic fragment. After im...
