IET Signal Processing, Volume 2026, Issue 1, 2026.The implementation of Kalman filter (KF) in tracking high‐dimensional, strongly correlated graph structured data is often complex and unstable. Meanwhile, in practical applications, the system may be subject to interference from non‐Gaussian noise and various cyberattacks.

The Impact of Special Economic Zones on Border Regions in Mexico
Bulletin of Economic Research, Volume 78, Issue 1, Page 224-231, January 2026.ABSTRACT We analyze the effects of a major tax reduction and a doubling of the minimum wage in the Northern region of Mexico, using a synthetic control approach. This quasi‐natural experiment allows us to isolate the impact of a 50% value‐added tax cut, a 30% income tax (Impuesto Sobre la Renta, ISR) reduction, and a significant wage increase on ...

On the Disentanglement of an Economic Union
Journal of Regional Science, Volume 66, Issue 1, Page 244-269, January 2026.ABSTRACT We study how the unilateral withdrawal of a region from an economic union affects the spatial distribution of economic activity and social welfare. We explore a three‐region economic geography model under the assumption that this withdrawal can be expressed as a higher transportation cost between the leaving party and the remaining union ...

Partial Observability of Implied Volatility Matrices: Identification and Covolatilities Filtering
Mathematical Finance, Volume 36, Issue 1, Page 48-66, January 2026.ABSTRACT Whereas data on implied volatilities are available for a large number of assets, this is less frequently the case of implied covolatilities. We introduce a new approach based on static and dynamic Wishart models to solve this problem of missing data.

Studies in Applied Mathematics, Volume 156, Issue 1, January 2026.ABSTRACT We study asymptotic dynamics of Kuramoto oscillators with inertia and frustration using the classical perturbation theory of ordinary differential equation systems. Frustration also known as the phase‐lag poses challenges for the mathematical analysis of asymptotic dynamics due to the breakdown of total phase conservation and the gradient ...

Asymptotic Profiles and Disease Prevalence at the Steady State for an SIS Patch Model
Studies in Applied Mathematics, Volume 156, Issue 1, January 2026.ABSTRACT Infected individuals often display mobility patterns that differ significantly from those of healthy individuals—traveling less frequently, covering shorter distances, visiting fewer destinations, and altering their timing and modes of movement.
