Trust and Income Among Immigrants in Europe

Kyklos, Volume 78, Issue 4, Page 1496-1513, November 2025.
ABSTRACT Social trust, a key cultural trait influencing economic behavior, plays a critical yet understudied role in immigrant integration. This paper examines how trust, both as an individual disposition and as a culturally inherited norm, relates to the economic integration of immigrants in Europe, measured by household income.

Kernel methods for the approximation of the eigenfunctions of the Koopman operator

Physica D: Nonlinear Phenomena
The Koopman operator provides a linear framework to study nonlinear dynamical systems. Its spectra offer valuable insights into system dynamics, but the operator can exhibit both discrete and continuous spectra, complicating direct computations. In this paper, we introduce a kernel-based method to construct the principal eigenfunctions of the Koopman ...

Pattern of extra‐diaphragmatic respiratory muscle activity during exercise in patients with unilateral diaphragm dysfunction

Physiological Reports, Volume 13, Issue 21, November 2025.
Abstract Whether extra‐diaphragmatic respiratory muscle output is altered in patients with unilateral diaphragm dysfunction (UDD) remains unclear. We compared respiratory pressures and muscle activity during symptom‐limited cardiopulmonary exercise testing (CPET) in 10 patients with UDD and 10 matched controls.

Data‐driven forecasting of ship motions in waves using machine learning and dynamic mode decomposition

International Journal of Adaptive Control and Signal Processing, Volume 39, Issue 10, Page 2119-2142, October 2025.
Summary Data‐driven forecasting of ship motions in waves is investigated through feedforward and recurrent neural networks as well as dynamic mode decomposition. The goal is to predict future ship motion variables based on past data collected on the field, using equation‐free approaches.

Agency and Opportunity in Early Adolescence: Investigating Gender‐Specific Patterns in Developmental Trajectories Using Longitudinal Data

Journal of Adolescence, Volume 97, Issue 7, Page 1921-1940, October 2025.
ABSTRACT Introduction Little research has explored the relationship of opportunity structures, such as parental influence and neighborhood context, with the development of individual agency amongst adolescents, particularly in understanding gender‐specific relationships.
