Abstract: A method includes determining a first set of atomic interactions between a first set of atoms and a second set of atoms using a molecular interaction model (EPh), providing inputs to a set of neural network models (dENN) to determine a second set of atomic interactions between the first set of atoms and the second set of atoms and training the dENN by reducing an error between an interaction produced by a combination of the first set of atomic interactions and the second set of atomic interactions and an interaction between the first set of atoms and the second set of atoms computed using quantum mechanical methods. The method includes reducing an error between the interaction produced by the combination of the first set of atomic interactions and the second set of atomic interactions and the interaction between the first set of atoms and the second set of atoms.

Abstract: A wheel end assembly includes a hub connectable with a wheel and having a bore for receiving a shaft. An inboard bearing within the bore includes an outer ring coupled with hub, an inner ring within the outer ring and rolling elements. A seal assembly is coupled with the inner ring and retains the inner ring within the outer ring when the end assembly is separate from the shaft. An outboard bearing within the hub bore includes an outer ring coupled with the hub, an inner ring within the outer ring and rolling elements. A nut assembly is disposed adjacent to the outboard bearing and includes a nut threadably engaging the shaft. A retainer retains the nut assembly adjacent to the outboard bearing to limit axial displacement of the outboard inner ring to maintain the inner ring within the outer ring when the wheel end is separate from the shaft.

Abstract: In some embodiments, a method includes determining an atom type of each atom from a set of atoms in a functional group of a molecular system. The method includes calculating, based on the set of atom types, a first set of ab initio molecular properties of a monomer and a second set of ab initio molecular properties of a multimer. The method further includes determining a set of parameters of a force field model by fitting the force field model to the first set of ab initio molecular properties and the second set of ab initio molecular properties until at least an agreement reaches a pre-determined threshold. The method includes determining, based on the set of parameters and the force field model, a molecular property of the molecular system and sending a signal to present the molecular property of the molecular system.

Abstract: This disclosure covers computer-implemented methods, non-transitory computer readable media, and systems that improve efficiency, accuracy, and flexibility in servicing provider vehicles associated with a transportation matching system. For example, the disclosed systems can match transportation provider vehicles to vehicle services at one or more multi-track vehicle service centers, guide provider vehicles through various tracks and services, and generate user interfaces for accurately and efficiently notifying provider devices and technician devices as vehicles progress through the multi-track vehicle service centers.

Abstract: A coating system includes a coating chamber having a peripheral chamber wall, a top wall, and a bottom wall. The peripheral chamber wall defines a chamber center. A plasma source is positioned at the chamber center. The coating system also includes a sample holder that holds a plurality of substrates to be coated which is rotatable about the chamber center at a first distance from the chamber center. A first isolation shield is positioned about the chamber center at a second distance from the chamber center, the first isolation shield being negatively charged.

Abstract: The present invention comprises a test set-up (20) and method of testing a correlated double sampling circuit (CDS) (24) by using a sinusoidal test signal (22) for measuring linearity. The present invention generates a sinusoidal signal with two accurate and known levels at two different time points, as an input to the CDS. The cosinusoidal output of the CDS is then processed using an ADC (60) and processor (62) to check the functionality and linearity of the CDS circuit under test.
