Developing an automated active learning framework for Neural Network Potentials, focusing on accurately simulating bond-breaking in hexane chains through steered molecular dynamics sampling and assessing model transferability.
Abstract In this Data Descriptor, we present county-level electricity outage estimates at 15-minute intervals from 2014 to 2022. By 2022 92% of customers in the 50 US States, Washington DC, and Puerto Rico are represented. These data have been produced by Environment for Analysis Geo-Located Energy Information (EAGLE-I TM ) , a geographic information system visualization platform created Oak Ridge National Laboratory map population experiencing outages every 15 minutes county level. Although...
The two Koreas have failed to produce any meaningful achievements in military confidence-building measures, arms control, and reduction. Moreover, South Korea’s continued competitive edge over the North conventional weapons capability has driven Korea mitigate its inferiority by pursuing dangerous course of nuclear armament. This article attempts understand evolving nature spending race on Korean peninsula. first section analyzes evaluates dynamics race. second empirically compares patterns...
Recent increases in extreme weather events such as severe thunderstorms, floods, and hurricanes are leading to destruction power system equipment (transmission distribution poles lines, substations, plants, etc.) causing widespread prolonged outages. These outages often cause inconveniences critical services (health care, transportation, national security, significant losses the economy, human suffering. Therefore, understanding spatiotemporal correlation of these with systems is crucial...
Recent progress in high-performance computing and data informatics has opened up numerous opportunities to aid the design of advanced materials. Herein, we demonstrate a computational workflow that includes rapid population high-fidelity materials datasets via petascale subsequent analyses with modern science techniques. We use first-principles approach based on density functional theory derive segregation energies 34 microalloying elements at coherent semi-coherent interfaces between...
Abstract A large number of microstructural parameters and a wide range transport physics impose challenges on thermal analysis alloy. Herein, modern data science techniques are employed to overcome the challenges, pursuing effective calculation properties. This emerging approach is tested for precipitate‐hardened aluminum (Al) alloy with consideration precipitate morphology. The finite element method (FEM) create database conductivity hypothetical Al alloys varying morphological features....
While future terabit networks hold the promise of significantly improving big-data motion among geographically distributed data centers, significant challenges must be overcome even on today's 100 gigabit to realize end-to-end performance. Multiple bottlenecks exist along path from source sink, for instance, storage infrastructure at both and sink its interplay with wide-area network are increasingly bottleneck achieving high In this paper, we identify issues that lead congestion an transfer...
As in the case of two-dimensional topology design optimization, numerical instability problems similar to formation checkerboard patterns occur if standard eight-node conforming brick element is used. Motivated by recent success non-conforming elements completely eliminating patterns, we aim at investigating performance three-dimensional controlling that are estimated overly stiff elements. To this end, will investigate how accurately estimate stiffness patterns. The estimation based on...
