Several sets of OPLS parameters have been published. There is OPLS-ua (united atom), which includes hydrogen atoms next to carbon implicitly in the carbon parameters, and can be used to save simulation time. OPLS-aa (all atom) includes every atom explicitly.
OPLS-AA, MMFF, GBSA solvent model, conformational sampling, minimizing, MD. Includes the Maestro GUI which provides visualizing, molecule building, calculation setup, job launch and monitoring, project-level organizing of results, access to a suite of other modelling programs.
Structures up to ten thousands of atoms can be analyzed on a workstation, and up to a billion atoms using supercomputing. Examples include properties of metals and alloys, [ 22 ] [ 23 ] mineral-organic interfaces, [ 24 ] protein- and DNA-nanomaterial interactions, [ 25 ] earth and building materials, carbon nanostructures, batteries, and ...

The total Coulomb energy is a sum over all pairwise combinations of atoms and usually excludes 1, 2 bonded atoms, 1, 3 bonded atoms, as well as 1, 4 bonded atoms [clarify]. [ 10 ] [ 11 ] [ 12 ] Atomic charges can make dominant contributions to the potential energy, especially for polar molecules and ionic compounds, and are critical to simulate ...

Over the course of eight years, Riley, now 39, hosted numerous fundraisers, both in person and online, gathering hundreds of supporters who donated more than $100,000 to fund her life-saving ...
At the time, enthusiasm was running high that Musk's fierce support of Trump would unlock big-time profits as driverless cars would get quicker approval — among other bullish lines of thinking.
