Selecting one out of six stereoisomers

Six out of equilibrium lectures

1 Preface The purpose of these notes is to introduce a group of subjects in out of equilibrium statistical mechanics that have received considerable attention in the last fifteen years or so. They are mostly connected with time-reversibility and its relation to entropy, are expressed in terms of large deviations, and involve at some level the notion of timescale-separation. We shall consider sy...

Six Studies of Out-of-Body Experiences

Because of confusion between science and scientism, many people react negatively to the idea of scientific investigation of near-death experiences (NDEs), but genuine science can contribute a great deal to understanding NDEs and helping experiencers integrate their experiences with everyday life. After noting how scientific investigation of certain parapsychological phenomena has established a ...

The Leave - one - out

Decoding One Out of Many

Generic decoding of linear codes is the best known attack against most code-based cryptosystems. Understanding and measuring the complexity of the best decoding technique is thus necessary to select secure parameters. We consider here the possibility that an attacker has access to many cryptograms and is satisfied by decrypting (i.e. decoding) only one of them. We show that, in many cases of in...

Controlling the formation of 1 out of 64 stereoisomers using organocatalysis.

The formation of 1 out of 64 stereoisomers, i.e. controlling the creation of 6 stereocenters, of important optically active bicyclo[3.3.1]non-2-ene compounds, has been achieved using organocatalysis; the reaction proceeds with excellent stereocontrol and can be carried out with the generation of enantiopure products using chromatography-free procedures.
