An optimization perspective on log-concave sampling and beyond
… applications to functional inequalities, the entropic barrier, Wasserstein barycenters, variational inference, and diffusion models.

Characterization of nanopores with internal cavities for DNA manipulation using Langevin dynamics simulations
… between the driving electric force field and the entropic barrier that must be overcome in order for the polymer to exit the internal cavity. More detailed characterization of the system over a range of simulation parameters elucidate the physical mechanisms important to this mechanism. Using …

Energy and topology of heteropolymers
… diffusion, and are affected only weakly by the entropic barrier created by the hole. Next we survey the energetics of random sequence heteropolymers, searching for "typical" properties of a sequence using lattice models. By enumerating the states and energies of compact 18, 27, and 36mers on a …

Mechanistic Studies of Bimolecular Electron Transfer Self-Exchange Rates of Ruthenium Ammine Pyridyl Complexes Measured by NMR Line Broadening Techniques
… hexacyano series is due to a increased enthalpic barrier and less negative entropic barrier.</p>

Observation and Nature of Non-statistical Dynamic Effects in Ordinary Organic Reactions
… for three DA reactions. We envision that the entropic barrier may have several experimental consequences such as unusual isotope effects due to extensive recrossing. Preliminary results for the organocatalytic reaction show an intramolecular KIE close to unity that cannot be reconciled with …

Laser-assisted single-molecule refolding
… analysis was adopted to fit the enthalpic and entropic height of the inter-conversion barrier. Our results suggest that for inter-conversion to occur, surprisingly, a small number of interactions are broken. However inter-conversion is rare due to a large negative entropic term. Negative …
