DOI: 10.1002/jcc.25772
Abstract: The conversion of polymer parameterization from internal coordinates (bond lengths, angles, and torsions) to Cartesian coordinates is a fundamental task in molecular modeling, often performed using the natural extension reference frame (NeRF) algorithm. NeRF can… read more here.

DOI: 10.1007/s10714-017-2333-5
Abstract: We consider a particle falling into a rotating black hole. Such a particle makes an infinite number of revolutions n from the viewpoint of a remote observer who uses the Boyer–Lindquist type of coordinates. We… read more here.

DOI: 10.1021/jacs.2c02389
Abstract: The transport coefficients, in particular the transference number, of electrolyte solutions are important design parameters for electrochemical energy storage devices. The recent observation of negative transference numbers in PEO–LiTFSI under certain conditions has generated much… read more here.

DOI: 10.1029/2022gl101173
Abstract: Interferometric Synthetic Aperture Radar is used to measure deformation rates over continents to constrain tectonic processes. The resulting velocity measurements are only relative, however, due to unknown integer ambiguities introduced during propagation of the signal… read more here.

Abstract: We construct an alternative uniformly accelerated reference frame based on 3+1 formalism in adapted coordinate. It is distinguished with Rindler coordinate that there is time-dependent redshift drift between co-moving observers. The experimentally falsifiable distinguishment might… read more here.
