Advantages of the Rayleigh-Lowe-Andersen thermostat in soft sphere molecular dynamics simulations.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The Rayleigh-Lowe-Andersen thermostat is a momentum-conserving, Galilean-invariant analogue of the Andersen thermostat, like the original (Maxwellian) Lowe-Andersen thermostat. However, the Rayleigh-Lowe-Andersen thermostat remains local even if the fluid density becomes low. By using a minimized thermostat interaction radius we show with a molecular dynamics simulation that the Rayleigh-Lowe-Andersen thermostat affects the natural dynamics of a low-density Lennard-Jones fluid in a minimal fashion. We also show that it is no longer necessary to consider a separate simulation just to determine the optimal value of the thermostat interaction radius. Instead, this value is computed directly during the main simulation run. Because the Rayleigh-Lowe-Andersen thermostat can be combined with the velocity Verlet integration scheme, we expect a widespread applicability of the thermal mechanism presented here.
