Complexity in quantum systems [PDF]
Physical Review E, 1994 We discuss the behavior of a quantum 1/2 spin coupled to a time dependent magnetic field, which can be quasiperiodic or random. For a quasiperiodic field, the time evolution of the system on a coarse grained space has autocorrelation, which does not decay, and positive topological entropy. The information complexity diverges as a stretched exponential,

On the challenges of predicting microscopic dynamics of online conversations
Applied Network Science, 2021 To what extent can we predict the structure of online conversation trees? We present a generative model to predict the size and evolution of threaded conversations on social media by combining machine learning algorithms.

Complex clients - complex systems? [PDF]
South Pacific Journal of Psychology, 2001 I would like to start with a tale… Exposure 'Some time ago a clinical psychologist registrar noted, vexedly, that it was all very well knowing what her clients needed to do if they were to improve, but it was no use at all when they stubbornly refused to adopt or deploy such life enhancing strategies.

Modeling complex systems [PDF]
Agricultural Economics, 2010 AbstractEmpirical observations suggest that linear dynamics are not an adequate representation of ecological systems and that a realistic representation would require adoption of complex nonlinear dynamical systems with characteristics encountered in complex adaptive systems (CAS).

Complexity: against systems [PDF]
Theory in Biosciences, 2011 This article assumes a specific intuitive notion of complexity as a difficulty to generate and/or assess the plausibility of models. Based on this intuitive understanding of complexity, it identifies two main causes of complexity, namely, radical openness and contextuality. The former is the idea that there are no natural systems.

Complex Neuro-Cognitive Systems [PDF]
, 2011 Cognitive functions such as a perception, thinking and acting are based on the working of the brain, one of the most complex systems we know. The traditional scientific methodology, however, has proved to be not sufficient to understand the relation ...

Femtosecond electron microscopy of relativistic electron bunches
Light: Science & Applications, 2023 The development of plasma-based accelerators has enabled the generation of very high brightness electron bunches of femtosecond duration, micrometer size and ultralow emittance, crucial for emerging applications including ultrafast detection in material ...

Complex Systems: A Survey [PDF]
, 2011 A complex system is a system composed of many interacting parts, often called agents, which displays collective behavior that does not follow trivially from the behaviors of the individual parts.
