Propagating Neural Waves: Combined Experimental and Modelling Study. The project is designed to measure propagating neural waves in visual areas of the brain to discover why and how they are created, how they interact with sensory inputs, and whether they can support brain plasticity and learning. Recent analysis of the brain’s electrical signals has showed that nerve cell activity is often organised into propagating waves, but how these waves are created, and what role they play in brain inform ....Propagating Neural Waves: Combined Experimental and Modelling Study. The project is designed to measure propagating neural waves in visual areas of the brain to discover why and how they are created, how they interact with sensory inputs, and whether they can support brain plasticity and learning. Recent analysis of the brain’s electrical signals has showed that nerve cell activity is often organised into propagating waves, but how these waves are created, and what role they play in brain information processing, remains unknown. The project plans to develop new methods for processing large-scale neural data, and to apply these methods to learn about propagating neural waves. These results may improve our understanding of how neural circuits function, eventually leading to clinical and technological advances.Read moreRead less
Mathematical model reduction for complex networks. This project aims to develop new mathematical methodology to describe the collective behaviour of large networks of oscillators with parameters called collective coordinates. This will allow for the quantitative description of finite-size networks as well as chaotic dynamics, which are both out of reach for current model reduction methods. The project will apply methodology to understand the causes of, and ways to prevent, glitches and failure i ....Mathematical model reduction for complex networks. This project aims to develop new mathematical methodology to describe the collective behaviour of large networks of oscillators with parameters called collective coordinates. This will allow for the quantitative description of finite-size networks as well as chaotic dynamics, which are both out of reach for current model reduction methods. The project will apply methodology to understand the causes of, and ways to prevent, glitches and failure in the emerging modern decentralised power grids. This will develop a framework to address this question, tailored to deal with the hitherto uncharted case of finite-size networks.Read moreRead less

This project aims to transform the understanding of the structure and function of the brain as a complex physical system. It aims to reveal and unify new aspects of information processing, transitions in conscious state, and nonlinear brain interactions by translating and applying concepts and methods from physics and mathematics. It will treat brain structure and dynamics together to address emergent phenomena like waves and patterns on multiple scales, treating waves as equal participants alongside neurons. Innovative predictions of brain phenomena will aim to be verified against data and used to understand brain networks, dynamics, and the physical phenomena underlying information processing and consciousness.Read moreRead less
Hydraulic Systems and State Development in Early Cambodia: Mapping the Engineered Landscapes of the Khmer Using Remote Sensing. Due to recent discoveries, Australian research at Angkor, in Cambodia, has gained increasing visibility worldwide. The ARC-funded Greater Angkor Project (Discovery) and Living With Heritage project (Linkage) have produced results of international significance, developed strong long-term partnerships with Cambodian agencies and UNESCO, and have pioneered the large-scale ....Hydraulic Systems and State Development in Early Cambodia: Mapping the Engineered Landscapes of the Khmer Using Remote Sensing.

The ARC-funded Greater Angkor Project (Discovery) and Living With Heritage project (Linkage) have produced results of international significance, developed strong long-term partnerships with Cambodian agencies and UNESCO, and have pioneered the large-scale mapping of World Heritage-listed sites using airborne imaging radar systems in collaboration with NASA. This project will extend these partnerships, consolidate Australia's leading position in radar analysis methods, and continue to produce results with global implications for the understanding and management of World Heritage sites.Read moreRead less
Integrated data-tested theory and modelling of type three solar radio emissions. Type three solar radio emissions, the Sun's most powerful and common, are the archetypal collective radio phenomenon in space physics and astrophysics. The project will integrate new theoretical work and simulations into a first integrated data-tested theory that can explain type three bursts, resolve long standing issues, and constrain solar physics.

Spatiotemporal dynamics and analysis of functional magnetic resonance imaging. Functional magnetic resonance imaging (fMRI) produces signals generated by brain activity in fine detail, but links between activity and images are poorly understood, posing a barrier to full use of the technology. Predictions from our new theory of such links will be made, tested experimentally and used to improve fMRI and discover new phenomena.

Relating function of complex networks to structure using information theory. This project aims to investigate networks in order to translate network function to a universal language of information flows. Network science has used common tools to reveal universal connection structures within various biological and man-made networks – our brains, social networks and power grids are all networks of interacting components. Yet there is no common method to study the function of these networks and how ....Relating function of complex networks to structure using information theory. This project aims to investigate networks in order to translate network function to a universal language of information flows. Network science has used common tools to reveal universal connection structures within various biological and man-made networks – our brains, social networks and power grids are all networks of interacting components. Yet there is no common method to study the function of these networks and how such function is coupled with structure. This project aims to relate network structure to function by using measures of information processing as a generally-applicable framework. This will deliver a theory of how structure gives rise to dynamics and how structure can be optimised for desired dynamics.Read moreRead less

Summary
The liver is important for both digestion and immunity. Given these opposing functions, the liver must exert control points that prevent the immune system from recognising food products. We have now identified a new molecular target that controls the development of immune cells in the liver.
The canonical stratification of jet spaces. Singularities occur everywhere in nature, from the formation and collapse of stars to the morphology of living embryos. They appear whenever the geometry of surfaces or spaces undergoes a process of twisting, folding, or collapsing on itself.

They appear whenever the geometry of surfaces or spaces undergoes a process of twisting, folding, or collapsing on itself. Singularity Theory is the study of such phenomena, an important branch of modern mathematics which has close connections with many other branches of mathematics and applied sciences. Singularity Theory lies at the crossroads of the paths connecting the most important areas of applications of mathematics with its most abstract parts. Analytic Singularity Theory is a central part of Singularity Theory. This project would lead to substantially new advancements in Analytic Singularity Theory.Read moreRead less
