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.

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.

From the ICU Bedside: Applying the Transnational Clinical Academic Doctorate Lens to a Clinically Embedded PhD Journey

Journal of Advanced Nursing, EarlyView.
ABSTRACT Aim To critically reflect on a transnational, clinically embedded doctoral journey undertaken during and after the COVID‐19 pandemic, and to draw conceptual and systemic lessons for doctoral education and clinical academic nursing pathways. Background Reflective accounts of doctoral study exist, yet few examine practice‐based PhDs conducted ...

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

Human and Intellectual Capital Spending Efficiency and Efficacy: Evidence from U.S. Universities

Journal of Business Finance &Accounting, EarlyView.
ABSTRACT We analyze the efficiency and efficacy of human and intellectual capital investment to better understand the effects of social investment. Existing literature in the corporate setting lacks analysis on the impact of human and intellectual capital investment, likely due to data scarcity.

Heterogeneous Effects of Monetary Policy Shocks: Evidence from the Czech Labor Market

Journal of Money, Credit and Banking, EarlyView.
Abstract Using unique contract‐level data from the Czech labor market, we investigate how monetary policy shocks, identified by the high‐frequency surprises in interest rate futures, affect the distribution of wages and hours worked. Consistent with existing literature, our findings indicate that low‐wage groups are more impacted by these shocks than ...

Frame Overlapping in Moral Markets: The Case of an ‘Open, Free, and Neutral’ Telecommunications Network

Journal of Management Studies, EarlyView.
Abstract This study explores how social movement activists, engaged in constructing and expanding moral markets, sustain the integrity of their initial moral values, avoiding dilution or cooptation by conventional market practices. Through a qualitative case study of a telecommunications network, we show that activists can expand a moral market by a ...
