Diffusion Characteristics of Ru and Oxygen Vacancies in Ta2O5 for Resistive Random Access Memory Devices: A Density Functional Theory Investigation

open access: yesAdvanced Electronic Materials, EarlyView.
Atomistic analysis of ruthenium (Ru) and oxygen vacancy (OV) diffusion in Ta₂O₅‐based memristors is performed. DFT calculations demonstrate interstitial Ru in Ta₂O₅ has lower diffusion barriers and formation energies than OVs, enhancing mobility and stability.

Graph‐based imitation and reinforcement learning for efficient Benders decomposition

open access: yesAIChE Journal, EarlyView.
Abstract This work introduces an end‐to‐end graph‐based agent for accelerating the computational efficiency of Benders Decomposition. The agent's policy is parameterized by a graph neural network, which takes as input a bipartite graph representation of the master problem and proposes a candidate solution.

Evaluation of the ENVI-Met Vegetation Model of Four Common Tree Species in a Subtropical Hot-Humid Area

open access: yesAtmosphere, 2018
Urban trees can significantly improve the outdoor thermal environment, especially in subtropical zones. However, due to the lack of fundamental evaluations of numerical simulation models, design and modification strategies for optimizing the thermal ...

Water ascends in woody plants : so what? [PDF]

open access: yes, 2013
Woody plants are often considered as static individuals, taking up water via the root system and losing it again via leaf transpiration. Quite boring one might conclude when considering that more than 95% of the water taken up by the roots is transpired ...

Characterizing the causes and consequences of calcium oxalate crystal presence in Vitis riparia

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Calcium oxalate biomineralization in plants is phylogenetically widespread and morphologically diverse, but the function of these inorganic crystals is an area of active debate. The variety of environmental conditions that produce the crystals, as well as the inconsistent evidence that they provide antiherbivore defense across plant ...
