  • SIDE models realistic biomolecular transition paths

    in

    What the study found The study found that SIDE, a Stochastic Integro-Differential Equation approach based on the Langevin bridge formalism, can generate realistic transition paths between different conformations of large biomolecular systems. In the authors' description, it produces smooth, low-energy trajectories and often recovers experimentally supported intermediate states. Why the authors say this matters The…

  • Thermostat choices affect sampling in molecular dynamics simulations

    —

    in

    What the study found Thermostat algorithms in constant-temperature molecular dynamics simulations do not all behave the same way. In this binary Lennard-Jones liquid glass-former model, the Nosé-Hoover chain and Bussi velocity-rescaling thermostats controlled temperature reliably, while the Grønbech-Jensen-Farago Langevin scheme gave the most consistent sampling of both temperature and potential energy. Why the authors say…
