Prediction method of thin sand reservoir with coal bearing: An example from PB area of Xihu Sag at East China Sea

地质科技通报
In the sedimentary environment shaped by river-tidal bidirectional flow, thin coal seams are typically located within the oil- and gas-bearing strata of the Pinghu Formation in the PB area of the Xihu Sag.

Movement Prediction using Reservoir Computing

International Journal of Computer Applications, 2013
1. ABSTRACT In this work the Reservoir Computing (RC) technique; specifically the Liquid State Machine (LSM) was chosen to simulate a Movement Predictor system at minimum cost, experiencing both short and long term prediction. Also in this work shows the possibility to simulate the LSM without the need to event based simulation (i.e. proving that it is

Optimizing seismic-based reservoir property prediction: a synthetic data-driven approach using convolutional neural networks and transfer learning with real data integration

Artificial Intelligence Review
Reservoir characterization through seismic data analysis is essential for exploration and production in the petroleum industry. However, seismic-to-well tie discrepancies, limited availability of high-quality well data, and resolution constraints pose a ...

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

A Comparative Study of Reservoir Computing for Temporal Signal Processing [PDF]

, 2014
Reservoir computing (RC) is a novel approach to time series prediction using recurrent neural networks. In RC, an input signal perturbs the intrinsic dynamics of a medium called a reservoir.

A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

FEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

Metastasis on pause: How dormant tumor cells stay hidden within the tumor microenvironment and evade immune surveillance

Molecular Oncology, EarlyView.
Dormant cancer cells can hide in distant organs for years, evading treatment and the immune system. This review highlights how signals from the surrounding tissue and immune environment keep these cells inactive or trigger their reawakening. Understanding these mechanisms may help develop therapies to eliminate or control dormant cells and prevent ...

Asymmetric Deep Co-Training Framework Using a Shape Context Descriptor for Reservoir Prediction: A Case Study from the Yinggehai Basin, South China Sea

Journal of Marine Science and Engineering
The scarcity and incompleteness of well-log data pose a critical challenge to deep learning-based reservoir prediction. To address this small-sample problem and improve prediction quality, we propose a novel semi-supervised asymmetric deep co-training ...

Continuous variable entanglement dynamics in structured reservoirs [PDF]

, 2009
We address the evolution of entanglement in bimodal continuous variable quantum systems interacting with two independent structured reservoirs. We derive an analytic expression for the entanglement of formation without performing the Markov and the ...
