Initial State Privacy of Nonlinear Systems on Riemannian Manifolds

open access: yesInternational Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT In this paper, we investigate initial state privacy protection for discrete‐time nonlinear closed systems. By capturing Riemannian geometric structures inherent in such privacy challenges, we refine the concept of differential privacy through the introduction of an initial state adjacency set based on Riemannian distances.

Sand in the Wheels: Corruption, Governance, and the Quest for Sustainable Development in Sub‐Saharan Africa

open access: yesSustainable Development, EarlyView.
ABSTRACT How do governance quality and corruption jointly shape sustainable development? We analyze an unbalanced panel of 38 Sub‐Saharan African countries (2002–2021) employing PCSE and FGLS estimators. The model also includes controls for health expenditure, digitalization, unemployment, trade openness, and GDP.
