Closing Trajectories: Equation‐Free Cyclic Animation via Koopman Surrogates
Computer Graphics Forum, EarlyView.Abstract Cyclic animation is widely used in computer graphics and interactive content. It supports seamless playback in games, VR, and interactive simulation, where short clips must repeat smoothly over long durations. Converting an observed non‐cyclic trajectory into a seamless loop is challenging because the endpoint states of the observed sequence ...

Post‐release survival, movement and marine migration of smolt‐to‐adult supplemented Atlantic Salmon
Journal of Fish Biology, EarlyView.Abstract Atlantic salmon (Salmo salar) populations are declining across much of their range, prompting the use of supplementation strategies, such as smolt‐to‐adult supplementation (SAS), to enhance adult returns. However, little is known about how captivity while maturing to adulthood influences post‐release survival, behaviour and migration of ...

Operator-theoretic approach to the partial integration of randomly coupled phase oscillators
Journal of Physics: ComplexityIn our previous work (Thibeault et al 2026 arXiv: 2504.06248 ), we adopted Koopman theory to link the existence of different constants of motion to the presence of specific network motifs of Kuramoto oscillators.

Data-Driven Identification of Gas Turbine Engine Dynamics via Koopman Operator Genetic Algorithm
IEEE AccessGas turbine engines (GTEs) are highly nonlinear control-nonaffine systems. Deriving their physics-based models can be challenging, particularly when some critical parameters can be difficult to measure or determine otherwise.

Capital‐Labour Substitution in Macroeconomics: A Survey of Mechanisms, Dynamics and Policy Insights
Journal of Economic Surveys, EarlyView.ABSTRACT Macroeconomic conclusions often hinge on a single, hard‐to‐pin‐down parameter: the elasticity of substitution between capital and labour, σ. This survey synthesises theory and evidence on how results change once we move beyond the Cobb–Douglas benchmark (σ=1$\sigma = 1$).

Deep Bilinear Koopman Model for Real-Time Vehicle Control in Frenet Frame
IEEE AccessAccurate modeling and control of autonomous vehicles remain a fundamental challenge due to the nonlinear and coupled nature of vehicle dynamics. While Koopman operator theory offers a framework for deploying powerful linear control techniques, learning a

Journal for the Scientific Study of Religion, EarlyView.ABSTRACT A longstanding debate in the sociology of religion has focused on how religious pluralism affects religious participation. Existing research shows mixed findings, often relying on macro‐level measures that overlook how individuals are actually exposed to religious pluralism in their lives. This study shifts focus to the meso‐level by examining
