By leveraging atomic-norm minimization (ANM)-based interpolation and Toeplitz rearrangement, a TRANM framework is proposed to address the rank-deficiency issue in the range-Doppler domain. To further enhance computational efficiency, we re-formulate the TRANM problem into an equivalent optimization with reduced dimensionality. The problem is then solved using the alternating direction method of multipliers, which provides an optimal solution via an iterative process. Numerical simulations validate that the proposed approach can accurately resolve coherent signals with improved degrees of freedom and achieve super-resolution, all while maintaining a low computational cost.}, language = {en} } @misc{HeinerYangLiu, author = {Heiner, Monika and Yang, Ming and Liu, Fei}, title = {Modeling and analyzing biological systems using colored hierarchical Petri nets illustrated by C. elegans vulval development}, series = {Journal of Biological Systems}, volume = {22}, journal = {Journal of Biological Systems}, number = {3}, issn = {1793-6470}, doi = {10.1142/S0218339014500181}, pages = {463 -- 493}, language = {en} } @misc{LiuHeiner, author = {Liu, Fei and Heiner, Monika}, title = {Modeling membrane systems using colored stochastic Petri nets}, series = {Natural Computing}, volume = {12}, journal = {Natural Computing}, number = {4}, issn = {1572-9796}, doi = {10.1007/s11047-013-9367-8}, pages = {617 -- 629}, language = {en} } @misc{LiuHeiner, author = {Liu, Fei and Heiner, Monika}, title = {Multiscale modelling of coupled Ca2+ channels using coloured stochastic Petri nets}, series = {IET Systems Biology}, volume = {7}, journal = {IET Systems Biology}, number = {4}, issn = {1751-8849}, pages = {106 -- 113}, language = {en} } @inproceedings{HerajyLiuRohr, author = {Herajy, Mostafa and Liu, Fei and Rohr, Christian}, title = {Coloured hybrid Petri nets for systems biology}, series = {Proceedings of the 5th International Workshop on Biological Processes \& Petri Nets (BioPPN)}, booktitle = {Proceedings of the 5th International Workshop on Biological Processes \& Petri Nets (BioPPN)}, editor = {Heiner, Monika}, pages = {60 -- 76}, language = {en} } @inproceedings{LiuHeiner, author = {Liu, Fei and Heiner, Monika}, title = {Coloured Petri Nets to Model and simulate Biological Systems}, series = {Proceedings of the Workshops of the 31st International Conference on Application and Theory of Petri Nets and Other Models of Concurrency (PETRI NETS 2010)}, booktitle = {Proceedings of the Workshops of the 31st International Conference on Application and Theory of Petri Nets and Other Models of Concurrency (PETRI NETS 2010)}, pages = {70 -- 84}, language = {en} } @incollection{LiuHeiner, author = {Liu, Fei and Heiner, Monika}, title = {Petri Nets for Modeling and Analyzing Biochemical Reaction Networks}, series = {Approaches in Integrative Bioinformatics}, booktitle = {Approaches in Integrative Bioinformatics}, editor = {Chen, Ming and Hofest{\"a}dt, Ralf}, publisher = {Springer}, address = {Heidelberg}, isbn = {978-3-642-41280-6}, doi = {10.1007/978-3-642-41281-3_9}, pages = {245 -- 272}, language = {en} } @misc{LiuHeinerYang, author = {Liu, Fei and Heiner, Monika and Yang, Ming}, title = {Representing Network Reconstruction Solutions with Colored Petri Nets}, series = {Neurocomputing}, volume = {174}, journal = {Neurocomputing}, number = {A}, issn = {0925-2312}, doi = {10.1016/j.neucom.2015.04.112}, pages = {483 -- 493}, language = {en} } @misc{LiuHeinerYang, author = {Liu, Fei and Heiner, Monika and Yang, Ming}, title = {Fuzzy stochastic Petri nets for modeling biological systems with uncertain kinetic parameters}, series = {PLoS ONE}, volume = {11}, journal = {PLoS ONE}, number = {2}, issn = {1932-6203}, doi = {10.1371/journal.pone.0149674}, pages = {0149674}, language = {en} } @misc{ParvuGilbertHeineretal., author = {P{\^a}rvu, Ovidiu and Gilbert, David and Heiner, Monika and Liu, Fei and Saunders, Nigel and Shaw, Simon}, title = {Spatial-temporal modelling and analysis of bacterial colonies with phase variable genes}, series = {ACM Transactions on Modeling and Computer Simulation (TOMACS)}, volume = {25}, journal = {ACM Transactions on Modeling and Computer Simulation (TOMACS)}, number = {2}, issn = {1558-1195}, doi = {10.1145/2742546}, pages = {13}, language = {en} }
