Agent-Based Modelling Approach for Multidimensional Opinion Polarization in Collective Behaviour

Journal of Artificial Societies and Social Simulation, 2017
Opinion polarization in a group is an important phenomenon in collective behaviour that has become increasingly frequent during periods of social transition. In general, an opinion includes several dimensions in reality.

Nonparametric Analysis of Household Labour Supply: Goodness-of-Fit and Power of the Unitary and the Collective Model [PDF]

We compare the empirical performance of the unitary and the collective approach to modelling observed labour supply behaviour. Deviating from the mainstream literature, we conduct a nonparametric analysis, which avoids the distortive impact of an ...

Overall Dynamic Body Acceleration in Straw-Colored Fruit Bats Increases in Headwinds but Not With Airspeed

Frontiers in Ecology and Evolution, 2019
Atmospheric conditions impact how animals use the aerosphere, and birds and bats should modify their flight to minimize energetic expenditure relative to changing wind conditions.

Tomonaga-Luttinger features in the resonant Raman spectra of quantum wires

, 2000
The differential cross section for resonant Raman scattering from the collective modes in a one dimensional system of interacting electrons is calculated non-perturbatively using the bosonization method.

Collective intelligence in animals and robots

Nature Communications
This comment explores how collective intelligence emerges from local interactions in animal groups, and how these principles inform the design of swarm robotic systems. It highlights the reciprocal value of robotics in studying biological collectives and

Probing the High Density Behaviour of Nuclear Symmetry Energy with High Energy Heavy-Ion Collisions

, 2002
High energy heavy-ion collisions are proposed as a novel means to constrain stringently the high density (HD) behaviour of nuclear symmetry energy. Within an isospin-dependent hadronic transport model, it is shown for the first time that the isospin ...

Non-invasive eye tracking and retinal view reconstruction in free swimming schooling fish

Communications Biology
Eye tracking has emerged as a key method for understanding how animals process visual information, identifying crucial elements of perception and attention.

Perceptual rationality: an evolutionary game theory of perceptually rational decision-making

Royal Society Open Science
Understanding how biological organisms make decisions is of fundamental importance for understanding behaviour. Such an understanding within evolutionary game theory, so far, has been sought by appealing to bounded rationality.

Monte Carlo Calculation of the Spin-Stiffness of the Two-Dimensional Heisenberg Model

, 1993
Using a collective-mode Monte Carlo method (the Wolff-Swendsen-Wang algorithm), we compute the spin-stiffness of the two-dimensional classical Heisenberg model.

Segmentation of laterally symmetric overlapping objects: application to images of collective animal behaviour

, 2019
Video analysis is currently the main non-intrusive method for the study of collective behavior. However, 3D-to-2D projection leads to overlapping of observed objects. The situation is further complicated by the absence of stall shapes for the majority of
