From the origin of life to pandemics: emergent phenomena in complex systems

Oriol Artime and Manlio De Domenico

Phil. Trans. Roy. Soc. A, Volume 380 Issue 2227

Theme issue ‘Emergent phenomena in complex physical and socio-technical systems: from cells to societies’

When a large number of similar entities interact among each other and with their environment at a low scale, unexpected outcomes at higher spatio-temporal scales might spontaneously arise. This non-trivial phenomenon, known as emergence, characterizes a broad range of distinct complex systems—from physical to biological and social—and is often related to collective behaviour. It is ubiquitous, from non-living entities such as oscillators that under specific conditions synchronize, to living ones, such as birds flocking or fish schooling. Despite the ample phenomenological evidence of the existence of systems’ emergent properties, central theoretical questions to the study of emergence remain unanswered, such as the lack of a widely accepted, rigorous definition of the phenomenon or the identification of the essential physical conditions that favour emergence. We offer here a general overview of the phenomenon of emergence and sketch current and future challenges on the topic. Our short review also serves as an introduction to the theme issue Emergent phenomena in complex physical and socio-technical systems: from cells to societies, where we provide a synthesis of the contents tackled in the issue and outline how they relate to these challenges, spanning from current advances in our understanding on the origin of life to the large-scale propagation of infectious diseases.

Mapping Philanthropic Support of Science

Louis M. Shekhtman, Alexander J. Gates, Albert-László Barabási
While philanthropic support plays an increasing role in supporting research, there is limited quantitative knowledge about the patterns that characterize the distribution of philanthropic support. Here, we map philanthropic funding to universities and research institutions based on IRS tax forms from 685,397 non-profit organizations. We identify nearly one million grants supporting institutions involved in science, finding that in volume and scope, philanthropic funding is comparable to federal research funding. However, whereas federal funding relies on a few large organizations to distribute grants, the philanthropic ecosystem's support is fragmented among a large number of funders with diverse focus that support research institutions at varying levels. Furthermore, we find that distinct from government support, philanthropic funders tend to focus locally, indicating that other criteria, beyond research excellence, play a role in their funding decisions. We also show evidence of persistence, i.e., once a grant-giving relationship begins, it tends to continue in time. Finally, we discuss the policy implications of our findings for philanthropic funders, individual researchers, the science of science, and for quantitative studies of philanthropy in general.

Everything You Need to Know About Tensors

Everything You Need to Know About Tensors | Complex Insight  - Understanding our world | Scoop.it
In this article, we will cover the basics of the tensors.
Phillip Trotter's insight:

Now tensors are just generalised n-dimensional arrays with a single datatype. They are are not new - (hint 1980's BASIC had them as did Fortran way before that though modern api's are much nicer to use) but they are essential to understanding much of modern data science especially Python/Numpy based approaches.  A good quick primer, for those either new to the field or for those old engineering hands who want to map their understanding and terminology from Fortran/ C++ / Matlab/ Euler / Mathematica etc to python data science approaches. Recommended.

HuggingFace Has Launched a Free Deep Reinforcement Learning Course

HuggingFace Has Launched a Free Deep Reinforcement Learning Course | Complex Insight  - Understanding our world | Scoop.it
Hugging Face has released a free course on Deep RL. It is self-paced and shares a lot of pointers on theory, tutorials, and hands-on guides.
Phillip Trotter's insight:

WE do a fair bit of reinforcement learning at Symbol Research so it is always good to come across useful resources we can recommend. HuggingFace make a lot of deep learning models easily accessible and recently launched a new RL training course. From a glance it looks similar to courses available from Udacity and others - but if you are looking for a course, with an easy to use Python API - HuggingFace will be a good starting point.

Phillip Trotter's insight:

The challenge with any new material is turning it from research into production and manufacturing at scale  (and as we learn from plastics - understanding its long term environmental impact)- however the insights from a new polymerization process developed at MIT promises some interesting developments if these challenges can be overcome.

Feeding the future

Feeding the future | Complex Insight  - Understanding our world | Scoop.it
Our global population is expected to hit 10 billion by 2050. Feeding the world without destroying the planet will mean farming smarter.
Phillip Trotter's insight:

If you have not grown up or worked around farming - it may not  at first seem high tech.. but it is (for example effective fertilizers and soil health encompass chemistry, ecology and biology and even basic equipment means mechanics, engineering, and control systems) and its about to become a lot more so - and that is not just the equipment such as robotic tractors that are making headlines but the entire approach to what we consider farming is at the early stages of a quiet revolution. CBC's Feeding the future  article gives a great insight into some of the changes we need to make and some of the changes being attempted.

A Ubiquitous Collective Tragedy in Transport

A Ubiquitous Collective Tragedy in Transport | Complex Insight  - Understanding our world | Scoop.it

 

Rafael Prieto Curiel, Humberto González Ramírez, and Steven Bishop

Front. Phys., 16 June 2022

A tragedy of the commons is said to occur when individuals act only in their own interest but, in so doing, create a collective state of a group that is less than optimal due to uncoordinated action. Here, we explore the individual decision-making processes of commuters using various forms of transport within a city, forming a modal share which is then built into a dynamical model using travel time as the key variable. From a randomised start in the distribution of the modal share, assuming that some individuals change their commuting method, favouring lower travel times, we show that a stable modal share is reached corresponding to an equilibrium in the model. Considering the average travel time for all commuters within the city, we show that an optimal result is achieved only if the direct and induced factors and the number of users are equal for all transport modes. For asymmetric factors, the equilibrium reached is always sub-optimal, leading to city travel trajectories being “tragic”, meaning that individuals choose a faster commuting time but create a slower urban mobility as a collective result. Hence, the city evolves, producing longer average commuting times. It is also shown that if a new mode of transport has a small baseline commuting time but has a high induced impact for other users, then introducing it might result in a counter-intuitive result producing more congestion, rather than less.

Phillip Trotter's insight:

Interesting study of transportation models and traffic congestion with a key insight being when being when individuals choose a faster commuting time their decision can often contribute to creating a slower urban mobility as a collective result m- something many of us experience daily.
