The ascending arousal system shapes neural dynamics to mediate awareness of cognitive states
Nature Communications, 2021 Models of brain organisation can overlook the role of the autonomic nervous system in cognitive processes. Here the authors show a link between the ascending arousal system and both low dimensional neural dynamics and internal shifts in conscious ...

Mathematical control of complex systems 2013 [PDF]
, 2014 Mathematical control of complex systems have already become an ideal research area for control engineers, mathematicians, computer scientists, and biologists to understand, manage, analyze, and interpret functional information/dynamical behaviours from ...

Dynamical modelling of superstatistical complex systems [PDF]
, 1996 We show how to construct the optimum superstatistical dynamical model for a given experimentally measured time series. For this purpose we generalise the superstatistics concept and study a Langevin equation with a memory kernel whose parameters ...

Stochastic Physics, Complex Systems and Biology [PDF]
, 2012 In complex systems, the interplay between nonlinear and stochastic dynamics, e.g., J. Monod's necessity and chance, gives rise to an evolutionary process in Darwinian sense, in terms of discrete jumps among attractors, with punctuated equilibrium ...

A stochastic view on surface inhomogeneity of nanoparticles
Nature Communications, 2019 Determining the spatial arrangement of molecules on a nanoparticle’s surface is key to understanding its interactions. Here, the authors use dSTORM imaging and probabilistic modelling to map the distribution of fluorophores on a nanoparticle, finding ...

Wavefront Shaping with Varying Degrees of Freedom [PDF]
EPJ Web of ConferencesOptical wavefront shaping employs the linearity of scattering to focus light through scattering media using spatial modulation. By selectively switching off weakly-contributing segments, we significantly improve optimization speeds with minimal intensity

What Makes Complex Systems Complex? [PDF]
, 2018 This paper explores some of the factors that make complex systems complex. We first examine the history of complex systems. It was Aristotle’s insight that how elements are joined together helps determine the properties of the resulting whole. We find (a)

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Oral mucositis is a common and debilitating side effect of childhood cancer and stem cell transplant treatments. It affects the quality of life of children and young people (CYP) and places a strain on services. Photobiomodulation is recommended for oral mucositis prevention in international guidance but is poorly implemented in UK ...

Are Innovation Systems Complex Systems?
, 2016 Basically, complex systems are defined as a large number of autonomous entities in interaction, that create several levels of collective organization leading to emergent (and immergent) behavior. In short, complex systems are characterized by the observation that the whole is more than the sum of the parts (Aristotle).

Evolutionary Subnetworks in Complex Systems
, 2009 Links in a practical network may have different functions, which makes the original network a combination of some functional subnetworks. Here, by a model of coupled oscillators, we investigate how such functional subnetworks are evolved and developed ...
