Maximizing Synchronization for Aligning Observed and Modelled Behaviour [chapter]

Vincent Bloemen, Sebastiaan J. van Zelst, Wil M. P. van der Aalst, Boudewijn F. van Dongen, Jaco van de Pol
2018 Lecture Notes in Computer Science  
Finally, we present a new algorithm for the computation of alignments on models with many log traces that is an order of magnitude faster (in maximizing synchronous moves) compared to the state-of-the-art  ...  An alignment for the model and σ is given by γ 0 (top right in Fig. 1) .  ...  We conclude that the max-sync cost function is complementary to the standard one as it provides an alternative view that may be preferable in some contexts, and it may also significantly reduce the alignment  ...

Mirroring and beyond: coupled dynamics as a generalized framework for modelling social interactions

Uri Hasson, Chris D. Frith
2016 Philosophical Transactions of the Royal Society of London. Biological Sciences  
This broader framework for understanding interactions can encompass both processes by which behaviour and brain activity mirror each other (neural alignment), and situations in which behaviour and brain  ...  One contribution of 15 to a theme issue 'Attending to and neglecting people'. When people observe one another, behavioural alignment can be detected at many levels, from the physical to the mental.  ...  We are grateful to Mai Nguyen, Janice Chen, Uta Frith and two anonymous referees for their help in preparing the final version of this paper.  ...

Modeling dynamical function: sparsely synchronized frameworks for deep brain stimulation?

Denis Larrivee
2018 Journal of Medicine and Therapeutics  
Existing evidence suggests, however, that its mechanism of operation is likely to be more complex and may be better framed as an interaction with sparsely synchronized frameworks for neural transmission  ...  High frequency electrical stimulation of deep brain structures, known as deep brain stimulation (DBS), has been successfully used to treat a number of refractory neurological, movement, and psychiatric  ...  behaviour, the Theory of Weakly Coupled Oscillation (TWCO) [13] and the sparse network model for synchronized communication [5, 14] .  ...

Alignment in social interactions

M. Gallotti, M.T. Fairhurst, C.D. Frith
2017 Consciousness and Cognition  
To understand the nature of social interactions, then, we propose that attention should be focused on the manner in which people align words and thoughts, bodily postures and movements, in order to take  ...  When individuals reciprocally exchange information about each other's minds processes of alignment unfold over time and across space, creating a social interaction.  ...  An interaction is not about discreet points of, for example, synchronization or coordination in space and time, but rather it is about the dynamic process of alignment that leads to those observed behaviours  ...

Emergence of polar order and cooperativity in hydrodynamically coupled model cilia

N. Bruot, P. Cicuta
2013 Journal of the Royal Society Interface  
In this system, the alignment depends on the state of synchronization of the system, and is therefore linked to the beat pattern of the model cilia.  ...  As a model of ciliary beat, we use two-state oscillators that have a defined direction of oscillation and have strong synchronization properties.  ...  Cosentino Lagomarsino for stimulating this work and providing a critical review.  ...

Observation of phase synchronization and alignment during free induction decay of quantum spins with Heisenberg interactions [article]

P. Vorndamme
2021 arXiv   pre-print
The synchronization is very robust against for instance random fluctuations of the Heisenberg couplings and inhomogeneous magnetic fields.  ...  Here, we observe mutual synchronization of local spin directions in closed systems under unitary time evolution.  ...  We see that ∆ has a very small impact on the time evolution and the behaviour of the spins; the process of alignment and the time it takes is very robust.  ...
