On the approximability of Koopman-based operator Lyapunov equations
, 2023 Lyapunov functions play a vital role in the context of control theory for nonlinear dynamical systems. Besides its classical use for stability analysis, Lyapunov functions also arise in iterative schemes for computing optimal feedback laws such as the ...

Koopman Operator for Stability Analysis: Theory with a Linear--Radial Product Reproducing Kernel
CoRRKoopman operator, as a fully linear representation of nonlinear dynamical systems, if well-defined on a reproducing kernel Hilbert space (RKHS), can be efficiently learned from data. For stability analysis and control-related problems, it is desired that the defining RKHS of the Koopman operator should account for both the stability of an equilibrium ...

Embracing Creative Nonconformists and Promoting Them May Require Leaders' High Control Appraisals
Journal of Organizational Behavior, Volume 47, Issue 5, Page 823-842, June 2026.ABSTRACT Promoting creative employees is essential to innovation and organizational success. However, leaders do not always embrace the nonconformist nature of creative behaviors. This study examines how leaders' control appraisals—a personal orientation reflecting their belief in their own ability to control situations—influence their receptiveness ...

ActuatorsOmni-directional mobile manipulators (OMMs) are inherently nonlinear, strongly coupled, and multiple-input multiple-output systems, posing significant challenges in developing accurate mechanistic models due to their complexity.

Molecular Reproduction and Development, Volume 93, Issue 6, June 2026.ABSTRACT Sex determination in Porifera remains one of the least understood aspects of early metazoan biology despite the group's key phylogenetic position. Sponges display exceptional diversity in sexual systems—ranging from stable gonochorism to sequential hermaphroditism and sex reversal—yet lack morphological dimorphism and any discrete gonadal ...

Applied Psychology: Health and Well-Being, Volume 18, Issue 3, June 2026.Abstract Does going the extra mile at work enhance an employee's well‐being, or does it come with hidden costs? With these two diverging perspectives on the impact of Organizational Citizenship Behaviors (OCBs) on employee well‐being and inconclusive previous meta‐analytic findings, the current study provides a much‐needed update.

Equivariance and partial observations in Koopman operator theory for partial differential equations
Journal of Computational DynamicsThe Koopman operator has become an essential tool for data-driven analysis, prediction and control of complex systems. The main reason is the enormous potential of identifying linear function space representations of nonlinear dynamics from measurements. This equally applies to ordinary, stochastic, and partial differential equations (PDEs). Until now,

Heterogeneous Effects of Monetary Policy Shocks: Evidence from the Czech Labor Market
Journal of Money, Credit and Banking, Volume 58, Issue 4, Page 995-1015, June 2026.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 ...
