Modelling the financial system as a network is a precondition to understanding and managing the containment of financial crises and the transition to a low-carbon economy. Financial Networks is the scientific discipline that deals with these issues. An article published in the scientific journal Nature Review Physics carries out the first comprehensive review of this field.
By virtually reproducing physical reservoir computing, a new information processing technology, using numerical simulation, the present study reveals that vortices in fluid flow phenomena in the downstream region of a cylinder are the key to information processing capability. It is expected that this result concerning fluid flow vortices and information processing capability will be useful in enhancing the information processing capability of the physical reservoir using fluid flow.
An extended epidemic model that accounts for uncertainty and the latest data can better predict the evolution of pandemics.
Financial institutions are linked together in a global web of interactions whose structure can be analyzed quantitatively by means of network theory. Today, 15 years after the 2007-2008 financial crisis, the role of networks for monitoring financial stability is widely recognized. Both policymakers and researchers agree that systemic risk has to be studied and managed by adopting a network perspective.
In a first-of-its-kind study, researchers used smart watches and a dedicated app to monitor 169 subjects before and during Israel's second COVID-19 lockdown (October 2020).
Mandating vaccination could have a substantial negative impact on voluntary compliance, according to research published today in PNAS.
After winning the FIFA World Cup, France could also win the European Football Championship - this is the conclusion of researchers from the Universities of Innsbruck (Austria) and Ghent (Belgium), the Technical Universities of Dortmund and Munich (Germany) and Molde University College (Norway). England and Spain also have a good chance of winning the title, according to the forecast.
In network science, the famous "friendship paradox" describes why your friends are (on average) more popular, richer, and more attractive than you are. But a slightly more nuanced picture emerges when we apply mathematics to real-world data.
A new study by ecologist André de Roos shows that differences between juveniles and adults of the same species are crucial for the stability of complex ecological communities. The research, published in Proceedings of the National Academy of Sciences, represents a major advance in ecological modeling at a time when biodiversity is declining and species around the world are rapidly going extinct.
In a new study published in Proceedings of the National Academy of Sciences (PNAS), a research team of the Institute of Complex Systems of the UB (UBICS) analysed the time evolution of real complex networks and developed a model in which the emergence of new nodes can be related to pre-existing nodes, similarly to the evolution of species in biology.
