It's the Politics!—Global Trade Governance Beyond Technocracy

Global Policy, EarlyView.
ABSTRACT The World Trade Organization (WTO) struggles to respond to the growing entanglement of trade and geopolitics. Drawing on existing scholarship and 20 in‐depth interviews with ambassadors and senior trade diplomats conducted in Geneva ahead of the 13th WTO Ministerial 2024, this article reveals a fundamental dilemma at the heart of contemporary ...

From Block-Oriented Models to the Koopman Operator: A Comprehensive Review on Data-Driven Chemical Reactor Modeling

Mathematics
Some chemical reactors exhibit coupled dynamics with multiple equilibrium points and strong nonlinearities. The accurate modeling of these dynamics is crucial to optimal control and increasing the reactor’s economic performance. While neural networks can

Koopman Operators in Robot Learning

Koopman operator theory offers a rigorous treatment of dynamics and has been emerging as an alternative modeling and learning-based control method across various robotics sub-domains. Due to its ability to represent nonlinear dynamics as a linear (but higher-dimensional) operator, Koopman theory offers a fresh lens through which to understand and ...

Volunteering While Researching Conflict and Violence: Reflections on Listening, Solidarity, and Decoloniality in Myanmar's Borderlands

Asia Pacific Viewpoint, EarlyView.
ABSTRACT Scholars working on conflict and violence often engage with local organisations, yet the methodological and ethical implications of volunteering‐while‐researching are rarely discussed in writing. This article contributes to debates on decolonizing research by conceptualising volunteering‐while‐researching as a practice that—while imbued with ...

A Koopman-Theoretic Approach to Car-Following and Multi-Lane Interaction Modeling

IEEE Open Journal of Intelligent Transportation Systems
This paper presents a Koopman operator-based approach for the car-following model using SwarmDMD, a dynamic mode decomposition (DMD)-type algorithm designed to capture multi-agent interactions.

Assessing Risk for Bycatch and Byproduct Species Using a Modified Sustainability Assessment for Fishing Effects (SAFE) Approach

Fish and Fisheries, EarlyView.
ABSTRACT Central to ecosystem‐based fisheries management is ensuring the sustainability of bycatch and byproduct species. However, the sustainability of these species is difficult to assess as the lack of information limits the use of traditional stock assessment methods.

Collaborative platooning and routing for mixed fleets of electric automated vehicles and conventional trucks

International Transactions in Operational Research, EarlyView.
Abstract The application of automated ground vehicles (AGVs) is well‐established in closed environments such as port terminals, while their operation in open areas remains challenging. In this work, we set out to overcome this limitation by introducing platooning as a transfer mode in heterogeneous vehicle networks.

Recursive Forward-Backward EDMD: Guaranteed Algebraic Search for Koopman Invariant Subspaces

IEEE Access
The implementation of the Koopman operator on digital computers often relies on the approximation of its action on finite-dimensional function spaces. This approximation is generally done by orthogonally projecting on the subspace.

Heterogeneous Mixtures of Dictionary Functions to Approximate Subspace Invariance in Koopman Operators: Why Deep Koopman Operators Work

Journal of Nonlinear Science
Abstract Koopman operators model nonlinear dynamics as a linear dynamic system acting on a nonlinear function as the state. This nonstandard state is often called a Koopman observable and is usually approximated numerically by a superposition of functions drawn from a dictionary. In a widely used algorithm, extended dynamic mode decomposition

Creativity Enactment in Ghanaian Secondary Visual Arts Programmes: An Autoethnographic Perspective

International Journal of Art &Design Education, EarlyView.
Abstract Creativity is regarded as one of the competencies of 21st‐century education and industry, and its enactment has been challenging for teachers and policymakers. This paper is an autoethnographic study that registers the accounts of the experiences and personal reflections of the lead researcher during his doctoral study, which explored ...
