Protection Degree and Migration in the Stochastic SIRS Model: A Queueing System Perspective
Yuhan Li, Ziyan Zeng, Minyu Feng +1
With the prevalence of COVID-19, the modeling of epidemic propagation and its analyses have played a significant role in controlling epidemics. However, individual behaviors, in pa…
Identification of single- and double-well coherence-incoherence patterns by the binary distance matrix
Vagner dos Santos, Matheus Rolim Sales, Sishu Shankar Muni +4
The study of chimera states or, more generally, coherence-incoherence patterns has led to the development of several tools for their identification and characterization. In this wo…
Teleconnections among Tipping Elements in the Earth System
Teng Liu, Dean Chen, Lan Yang +10
Tipping elements of the Earth system may shift abruptly and irreversibly from one state to another at tipping points, resulting in a growing threat to our society. Yet, it is not f…
Dynamic scaling and stochastic fractal in nucleation and growth processes
Amit Lahiri, Md. Kamrul Hassan, Bernd Blasius +1
A class of nucleation and growth models of a stable phase (S-phase) is investigated for various different growth velocities. It is shown that for growth velocities a…
Study of Interaction and Complete Merging of Binary Cyclones Using Complex Networks
Somnath De, Shraddha Gupta, Vishnu R Unni +5
Cyclones are amongst the most hazardous extreme weather events on Earth. When two co-rotating cyclones come in close proximity, a possibility of complete merger (CM) arises due to…
PrEF: Percolation-based Evolutionary Framework for the diffusion-source-localization problem in large networks
Yang Liu, Xiaoqi Wang, Xi Wang +2
We assume that the state of a number of nodes in a network could be investigated if necessary, and study what configuration of those nodes could facilitate a better solution for th…
Perspectives on the importance of complex systems in understanding ourclimate and climate change -- The Nobel Prize in Physics 2021
Shraddha Gupta, Nikolaos Mastrantonas, Cristina Masoller +1
The Nobel Prize in Physics 2021 was awarded to Syukuro Manabe, Klaus Hasselmann, and Giorgio Parisi for their 'groundbreaking contributions to our understanding of complex systems'…
Rijke tube: A nonlinear oscillator
Krishna Manoj, Samadhan A. Pawar, Jürgen Kurths +1
Dynamical systems theory has emerged as an interdisciplinary area of research to characterize the complex dynamical transitions in real-world systems. Various nonlinear dynamical p…
Ambient Forcing: Sampling Local Perturbations in Constrained Phase Spaces
Anna Büttner, Jürgen Kurths, Frank Hellmann
Ambient Forcing is a novel method to sample random states from manifolds of differential-algebraic equations (DAE). These states can represent local perturbations of nodes in power…
Predicting Basin Stability of Power Grids using Graph Neural Networks
Christian Nauck, Michael Lindner, Konstantin Schürholt +5
The prediction of dynamical stability of power grids becomes more important and challenging with increasing shares of renewable energy sources due to their decentralized structure,…
MFDFA: Efficient Multifractal Detrended Fluctuation Analysis in Python
Leonardo Rydin Gorjão, Galib Hassan, Jürgen Kurths +1
Multifractal detrended fluctuation analysis (MFDFA) has become a central method to characterise the variability and uncertainty in empiric time series. Extracting the fluctuations…
Anticipation-induced social tipping -- Can the environment be stabilised by social dynamics?
Paul Manuel Müller, Jobst Heitzig, Jürgen Kurths +2
In the past decades human activities caused global Earth system changes, e.g., climate change or biodiversity loss. Simultaneously, these associated impacts have increased environm…
Multi-task GANs for Semantic Segmentation and Depth Completion with Cycle Consistency
Chongzhen Zhang, Yang Tang, Chaoqiang Zhao +3
Semantic segmentation and depth completion are two challenging tasks in scene understanding, and they are widely used in robotics and autonomous driving. Although several works are…
Rate-dependent bifurcation dodging in a thermoacoustic system driven by colored noise
Xiaoyu Zhang, Yong Xu, Qi Liu +2
Tipping in multistable systems occurs usually by varying the input slightly, resulting in the output switching to an often unsatisfactory state. This phenomenon is manifested in th…
