Nonstandard hulls of locally uniform groups [PDF]
arXiv, 2012 We present a nonstandard hull construction for locally uniform groups in a spirit similar to Luxembourg's construction of the nonstandard hull of a uniform space. Our nonstandard hull is a local group rather than a global group. We investigate how this construction varies as one changes the family of pseudometrics used to construct the hull. We use the

Convex hulls of face-vertex incident vectors of 3-colorable polytopes [PDF]
arXiv, 2021 The convex hulls of face-vertex incident vectors of 3-face-colorable convex polytopes are computed. It is found that every such convex hull is a $d$-polytope with $d+2$ or $d+3$ vertices. Utilizing Gale transform and Gale diagram, we calculate its combinatorial structure.

Screening and Development of Sacrificial Cathode Additives for Lithium‐Ion Batteries
Advanced Energy Materials, EarlyView.This work presents a computational screening approach to identify Li‐rich transition‐metal oxide sacrificial cathode additives and provides experimental validation of antifluorite‐structured Li6MnO4 as a potential candidate. Abstract This work presents a computational screening approach to identify Li‐rich transition‐metal oxide sacrificial cathode ...

ShipGen: A Diffusion Model for Parametric Ship Hull Generation with Multiple Objectives and Constraints [PDF]
arXiv, 2023 Ship design is a years-long process that requires balancing complex design trade-offs to create a ship that is efficient and effective. Finding new ways to improve the ship design process can lead to significant cost savings for ship building and operation.

Advanced Energy Materials, EarlyView.The double perovskite BaSrNiWO6 is developed as an oxygen evolution reaction catalyst. B‐site W6+ dissolution drives in situ reconstruction of the surface to a disordered, NiO‐like layer. Consequently, local oxygen species are activated for a surface lattice oxygen evolution mechanism (sLOEM).

Approximate Convex Hulls: sketching the convex hull using curvature [PDF]
arXiv, 2017 Convex hulls are fundamental objects in computational geometry. In moderate dimensions or for large numbers of vertices, computing the convex hull can be impractical due to the computational complexity of convex hull algorithms. In this article we approximate the convex hull in using a scalable algorithm which finds high curvature vertices with high ...

Advanced Energy Materials, EarlyView.The decomposition of Nb‐substituted LLZO solid electrolytes is reported through a propagating reaction between Nb5+ dopants and the Li metal electrode. This work suggests dopants that segregate to interfaces/grain boundaries in LLZO will exhibit reactivity that can propagate into bulk and shed light on new mechanisms for the problematic role of oxygen ...

Applied Economic Perspectives and Policy, EarlyView.Abstract Extreme weather events are worsening the fragile rural infrastructure in the United States, impacting trade flows of agricultural products. The Mississippi River, vital for transporting agricultural commodities, reached historic lows during the 2022 and 2023 fall harvests, increasing transportation costs and lowering crop prices.
