Many biological processes can be thought of as the result of an underlying dynamics in which the system repeatedly undergoes distinct and abortive trajectories with the dynamical process only ending when some specific process, purpose, structure or function is achieved. A classic example is the way in which…

The purpose of this paper is to present an idealized hypotheses-drawn model describing dynamics of variability in business and other social areas. A new construct is introduced, the Bayesian space of assessments, to consider changes in positions of individuals and intrinsically interrelated entities called social…

'Mario Di Bernardo' 'Ali Minai' 'Michael J. Richardson'] Humans commonly engage in tasks that require or are made more efficient by coordinating with other humans. In this paper we introduce a task dynamics approach for modeling multi-agent interaction and decision making in a pick and place task where an agent must…

Everyday activities, like jumping on a trampoline or using a swing-stick, show that humans seemingly effortless support systems in their intrinsically preferred motions. Although this observation seems obvious, data-based evidence proving that humans indeed match system dynamics has been lacking, since everyday objects…

Humans achieve locomotor dexterity that far exceeds the capability of modern robots, yet this is achieved despite slower actuators, imprecise sensors, and vastly slower communication. We propose that this spectacular performance arises from encoding motor commands in terms of dynamic primitives. We propose three…

— This paper presents a modular framework for motion planning using movement primitives. Central to the approach is Contraction Theory, a modular stability tool for nonlinear dynamical systems. The approach extends prior methods by achieving parallel and sequential combinations of both discrete and rhythmic movements…

Musicians sway expressively as they play in ways that seem clearly related to the music, but quantifying the relationship has been difficult. We suggest that a complex systems framework and its accompanying tools for analyzing non-linear dynamical systems can help identify the motor synergies involved. Synergies are…

An ongoing debate exists regarding the compatibility of dynamic systems theory (DST) and symbol processing accounts (SPA), where SPA assume abstract representations and processing. Another aspect under discussion is if either one appropriately describes and explains motor control and the modification of motor skills.…

— Our goal is to enable social robots to interact autonomously with humans in a realistic, engaging, and expressive manner. The 12 Principles of Animation [1] are a well-established framework animators use to create movements that make characters appear convincing, dynamic, and emotionally expressive. This paper…

The reemergence of virtual reality (VR) in the last few years has led to affordable commodity hardware that can offer new ways to teach, communicate and engage with difficult concepts, especially those which involve complicated 3D motion and spatial manipulation. In a higher education context, these immersive…

All animal behaviour must ultimately be governed by physical laws. As a basis for understanding the physics of behaviour in a simple system, we here develop an effective theory for the motion of the larval form of the fruitfly Drosophila melanogaster, and compare it against a quantitative analysis of the real animal’s…

We present DAISY, a web-based computational tool for the simulation of dynamic magnetic properties of single molecule magnets and supermagnetic nanoparticles. The tool is parametric and accepts relaxation parameters of different mechanisms, including Orbach, Raman, Quantum Tunneling of the Magnetization and the direct…

Coordinated actions are fundamental to human behavior. Even without explicit communication, stable coordination patterns and implicit leadership roles can emerge. This study examines the dynamic nature of leadership and its impact on perceptuomotor learning in a dyadic coordination task. Paired participants (dyads)…

This paper describes the use of spatially-sparse inputs to influence global changes in the behavior of Dynamic Movement Primitives (DMPs). The dynamics of DMPs are analyzed through the framework of contraction theory as networked hierarchies of contracting or transversely contracting systems. Within this framework…

Actin, a key component of the cytoskeleton in eukaryotic cells, plays a crucial role in regulating cell morphology and transport. The morphology, mechanical, and biochemical properties of these filaments and bundles are determined by their monomer structure and by protein-protein contacts. Crowded environments are…

'Giovanni Noselli' 'A. Piccolroaz'] The phenomenon of oscillatory instability called 'flutter' was observed in aeroelasticity and rotor dynamics about a century ago. Driven by a series of applications involving nonconservative elasticity theory at different physical scales, ranging from nanomechanics to the mechanics…

Machine olfaction—the artificial replication of the sense of smell—faces significant challenges due to the absence of large, standardized training datasets. Unlike vision, language, and audio models, which benefit from extensive corpora such as ImageNet, GLUE, and AudioSet, olfaction lacks scaled equivalents and…

In motor learning research, various whole-body movement tasks have been examined using a dynamical systems approach. Prior studies have highlighted that differences in learning strategies and variability in movement contribute to individual differences in motor learning. Building on these findings, this study…

Materials that exhibit actuation behaviour in response to external stimuli have a wide range of applications owing to their ability to convert input energy into mechanical work. Light and chemicals are common sources of input energy. However, actuation using thermal energy from ambient-temperature sources remains…

Mirroring is a foundational method used in Dance Movement Therapy (DMT), assumed to foster empathy and therapeutic attunement, yet its embodied dynamics remain insufficiently studied. In this paper, we provide the first quantitative exploration of client-therapist mirroring across dyadic and triadic formats, examining…

Percussion began as a global phenomenon over seven thousand years ago and has continued to develop and shape human culture to this day. While drumming techniques have been qualitatively optimized in highly competitive environments like international orchestral, jazz, and marching arts competitions, little quantitative…

Magnetic fluid shock absorbers (MFSAs) have been successfully applied in eliminating the micro-vibration of the spacecraft’s flexible structures. The method of enhancing the damping of MFSAs has always been the key issue. The tree frog’s toe pads exhibit the strong adhesion, which inspired us to learn from their…

In this article, two dance educators offer a definition of rhythm from both educational and performance perspectives and discuss pedagogical practices that waken students’ awareness to rhythm as a lived-experience over which they have creative control. For the dancer, in the midst of the dance, rhythms are, in the…
