Data Analysis on Critical Transitions in Complex Systems and its Application to Early Precision Medicine

October 25, 2021 – 09:00 pm (Japan Standard Time)

Prof. Kazuyuki Aihara will review his group’s recent studies on DNB (Dynamical Network Biomarkers) that provide early warning signals of imminent bifurcation from a healthy state to a disease state through a pre-disease state. He will also explain the possible application of DNB for early precision medicine.

Kazuyuki Aihara received a B.E. degree in electrical engineering and Ph.D. degree in electronic engineering from the University of Tokyo (UTokyo), Tokyo, Japan, in 1977 and 1982, respectively. He led the ERATO (Exploratory Research for Advanced Technology) Aihara Complexity Modelling project by JST (Japan Science and Technology Agency) from 2003 to 2008 and the FIRST Innovative Mathematical Modelling project by JSPS (Japan Society for the Promotion of Science) through the FIRST (Funding Program for World-Leading Innovative R&D Science and Technology) program from 2010 to 2014 designed by CSTP (Council for Science and Technology Policy). Currently, he is University Professor and Professor Emeritus of UTokyo,  Deputy Director at the International Research Center for Neurointelligence (IRCN) at UTokyo, and Project Manager of the Moonshot project by the cabinet office of the Japanese government on “Comprehensive Mathematical Understanding of the Complex Control System between Organs and Challenge for Ultra-Early Precision Medicine.”

Dr. Louis Pecora, NRL Washington

February 28, 2022

Dr. Lou Pecora is a research scientist at the Naval Research Laboratory, where he has been since 1977. There he heads a group in nonlinear dynamics of solid-state systems.

In 1990, together with Thomas Carroll, he demonstrated for the first time experimentally the control of chaotic systems via synchronization of chaos, a phenomenon that they discovered. In 2020, he and Thomas Carroll among the Clarivate Citation Laureates for research in nonlinear dynamics including synchronization of chaotic systems. His 1990 work with Thomas Carroll on the subject has been cited over 13,000 times.

Exploring Predictability of Extreme Climate Events via a Complex Network Approach

September 27, 2021 – 04:00 pm (Central European Time)

Earth is a complex system whose dynamics involve innumerous interactions and multiple feedbacks. This makes predictions and risk analysis of very strong, and sometime extreme events such as floods, landslides, heatwaves, earthquakes etc., a challenging task. Here, I will introduce a recently developed approach via complex networks to analyze strong climate events. This leads to an inverse problem: Is there a backbone-like structure underlying the climate system? Towards this, we propose a method to reconstruct and analyze a complex network from observational and reanalysis data. This approach enables us to uncover relations to global and regional circulation patterns in oceans and atmosphere, which leads to substantially better predictions of high-impact phenomena, in particular of the Indian Summer Monsoon, El Nino events, droughts in the central Amazon, extreme rainfall in the Eastern Central Andes, and the pacific decadal oscillation. I argue that network-based approaches can significantly complement numerical modelling for better predictions of extreme weather event and lead to better understanding of meteorological data.

Prof. Jürgen Kurths is Senior Advisor at Research Department for “Complexity Science” at Potsdam Institute for Climate Impact Research (PIK) as well as Professor and Senior Advisor at Humboldt University Berlin.
