Stochastic Molecular Reaction Queueing Network Modeling for In Vitro Transcription Process

no code implementations17 May 2023 Keqi Wang, Wei Xie, Hua Zheng

To facilitate a rapid response to pandemic threats, this paper focuses on developing a mechanistic simulation model for in vitro transcription (IVT) process, a crucial step in mRNA vaccine manufacturing.

Metabolic Regulatory Network Kinetic Modeling with Multiple Isotopic Tracers for iPSCs

no code implementations29 Apr 2023 Keqi Wang, Wei Xie, Sarah W. Harcum

In this paper, a metabolic kinetic model was developed to characterize underlying mechanisms of iPSC culture process, which can predict cell response to environmental perturbation and support process control.

Sequential Importance Sampling for Hybrid Model Bayesian Inference to Support Bioprocess Mechanism Learning and Robust Control

no code implementations5 May 2022 Wei Xie, Keqi Wang, Hua Zheng, Ben Feng

Driven by the critical needs of biomanufacturing 4. 0, we introduce a probabilistic knowledge graph hybrid model characterizing the risk- and science-based understanding of bioprocess mechanisms.

Linear Array Network for Low-light Image Enhancement

no code implementations22 Jan 2022 Keqi Wang, Ziteng Cui, Jieru Jia, Hao Xu, Ge Wu, Yin Zhuang, Lu Chen, Zhiguo Hu, Yuhua Qian

However, the convolution operation is based on a local sliding window mechanism, which is difficult to construct the long-range dependencies of the feature maps.

Opportunities of Hybrid Model-based Reinforcement Learning for Cell Therapy Manufacturing Process Control

no code implementations10 Jan 2022 Hua Zheng, Wei Xie, Keqi Wang, Zheng Li

Driven by the key challenges of cell therapy manufacturing, including high complexity, high uncertainty, and very limited process observations, we propose a hybrid model-based reinforcement learning (RL) to efficiently guide process control.

Extreme Low-Light Imaging with Multi-granulation Cooperative Networks

no code implementations16 May 2020 Keqi Wang, Peng Gao, Steven Hoi, Qian Guo, Yuhua Qian

Low-light imaging is challenging since images may appear to be dark and noised due to low signal-to-noise ratio, complex image content, and the variety in shooting scenes in extreme low-light condition.
