Developing an action concept inventory

Physical Review Physics Education Research, 2016
We report on progress towards the development of an Action Concept Inventory (ACI), a test that measures student understanding of action principles in introductory mechanics and optics.

A tmQCD mixed-action approach to flavour physics

EPJ Web of Conferences, 2018
We discuss a mixed-action approach in which sea quarks are regularised using non-perturbatively O(a) improved Wilson fermions, while a fully-twisted tmQCD action is used for valence quarks.

VLA-MP: A Vision-Language-Action Framework for Multimodal Perception and Physics-Constrained Action Generation in Autonomous Driving [PDF]

Sensors
Autonomous driving in complex real-world environments requires robust perception, reasoning, and physically feasible planning, which remain challenging for current end-to-end approaches.

The Long-Term Efficacy of “Social Buffering” in Artificial Social Agents: Contextual Affective Perception Matters

Frontiers in Robotics and AI, 2022
In dynamic (social) environments, an affective state of “stress” can be adaptive and promote agent wellbeing, but maladaptive if not appropriately regulated.

Action physics [PDF]

American Journal of Physics, 2016
More than a decade ago, Edwin Taylor issued a “call to action” that presented the case for basing introductory university mechanics teaching around the principle of stationary action [E. F. Taylor, Am. J. Phys. 71, 423–425 (2003)]. We report on our response to that call in the form of an investigation of the teaching and learning of the stationary ...

Causality in Discrete Time Physics Derived from Maupertuis Reduced Action Principle

Entropy, 2021
Causality describes the process and consequences from an action: a cause has an effect. Causality is preserved in classical physics as well as in special and general theories of relativity.

An algorithm for discovering Lagrangians automatically from data [PDF]

PeerJ Computer Science, 2015
An activity fundamental to science is building mathematical models. These models are used to both predict the results of future experiments and gain insight into the structure of the system under study.

A Dynamical, Radically Embodied, and Ecological Theory of Rhythm Development

Frontiers in Psychology, 2022
Musical rhythm abilities—the perception of and coordinated action to the rhythmic structure of music—undergo remarkable change over human development.

Multiple-Relaxation-Time Lattice Boltzmann Simulation of Soret and Dufour Effects on the Thermosolutal Natural Convection of a Nanofluid in a U-Shaped Porous Enclosure

Energies, 2023
This article reports an investigation of the Soret and Dufour effects on the double-diffusive natural convection of Al2O3-H2O nanofluids in a U-shaped porous enclosure.

Physics of Ice Nucleation and Antinucleation: Action of Ice-Binding Proteins

Biomolecules, 2023
Ice-binding proteins are crucial for the adaptation of various organisms to low temperatures. Some of these, called antifreeze proteins, are usually thought to inhibit growth and/or recrystallization of ice crystals.
