A method to determine nuclear magnetic resonance T2 cutoff value of tight sandstone reservoir based on multifractal analysis

Energy Science & Engineering, 2020
Nuclear magnetic resonance (NMR) T2 cutoff value is an important parameter for pore structure evaluation. It is complicated and uneconomical to obtain T2 cutoff value by an experimental method; therefore, it is necessary to explore a prediction method of

Leveraging Data Quality to Better Prepare for Process Mining: An Approach Illustrated Through Analysing Road Trauma Pre-Hospital Retrieval and Transport Processes in Queensland

International Journal of Environmental Research and Public Health, 2019
While noting the importance of data quality, existing process mining methodologies (i) do not provide details on how to assess the quality of event data (ii) do not consider how the identification of data quality issues can be exploited in the planning ...

Disordered Rocksalts as High‐Energy and Earth‐Abundant Li‐Ion Cathodes

Advanced Materials, EarlyView.
Disordered rocksalts with lithium excess (DRX) offer a new direction in Li‐ion cathode design beyond conventional Ni‐ and Co‐based materials. This review highlights the design principles, synthesis strategies, and performance optimization of DRX oxides and oxyfluorides for energy‐dense, sustainable batteries using Earth‐abundant transition metals and ...

Self-organization of the MinE ring in subcellular Min oscillations [PDF]

arXiv, 2009
We model the self-organization of the MinE ring that is observed during subcellular oscillations of the proteins MinD and MinE within the rod-shaped bacterium {\it Escherichia coli}. With a steady-state approximation, we can study the MinE-ring generically -- apart from the other details of the Min oscillation.

A systematic mapping study of process mining

Enterprise Information Systems, 2018
This study systematically assesses the process mining scenario from 2005 to 2014. The analysis of 705 papers evidenced ‘discovery’ (71%) as the main type of process mining addressed and ‘categorical prediction’ (25%) as the main mining task solved.

Coupled Solid‐State Diffusion of Li+ and O2 − During Fabrication of Ni‐Rich NMC Thin‐Film Cathodes Resulting in the Formation of Inactive Ni2O3 and NiO Phases

Advanced Materials Interfaces, EarlyView.
The degradation reactions for Ni‐rich NMC materials are discussed using a thin‐film model system. The loss of Li2O into the Pt current collector led to inactive NiO phases. Compensation by Li2CO3 deposited on top and the efficacy of a TiW diffusion barrier is demonstrated.

When Blockchain Meets AI: Optimal Mining Strategy Achieved By Machine Learning [PDF]

arXiv, 2019
This work applies reinforcement learning (RL) from the AI machine learning field to derive an optimal Bitcoin-like blockchain mining strategy without knowing the details of the blockchain network model. Previously, the most profitable mining strategy was believed to be honest mining encoded in the default blockchain protocol. It was shown later that it
