Comparison of ML-Based Proxy Modeling Strategies: Lessons Learned from the SMART Initiative Open
Teams of researchers on Task 5 of the SMART project have developed a variety of modeling architectures to predict subsurface behavior during carbon injection and post-injection periods. One important part of this task was to compare the ca…

The Remarkable Generality of the Transient Storage Model with Residence Time Dependence: Temporal Moments. Open
<p>Several distinct approaches to the one-dimensional modeling of river corridor transport at the macroscale have been developed as generalizations of the original Transient Storage Model (TSM).  We show that essentially all…

MARTINI-based Coarse-grained Model for Poly(alpha-peptoid)s Open
In this paper, we present a new coarse-grained (CG) model for poly (alpha-peptoid)s that is compatible with the MARTINI CG FF. In the proposed model, CG poly (alpha-peptoid) is composed by a CG backbone (here we select polysarcosine as the…
