Adaptive Observer for Coupled Wave PDE and Infinite ODE With Sampled Data and Unknown Input: Application to Brain Hemodynamics Estimation

International Journal of Adaptive Control and Signal Processing, Volume 40, Issue 9, Page 1932-1944, September 2026.
This article proposes a convergent adaptive observer for a damped wave PDE and an infinite‐dimensional ODE coupled in cascade using sampled‐in‐space ODE state measurements. The proposed observer estimates the distributed states of the PDE and ODE along with unknown PDE parameters and spatial input.

Chiral Altermagnetic Magnetoelectrics

Advanced Materials, Volume 38, Issue 52, 16 September 2026.
In this work, we introduce a previously unexplored class of magnetoelectric materials, which we term chiral altermagnetic magnetoelectrics, in which structural chirality and Néel‐vector‐driven polarization are intrinsically coupled in nonpolar altermagnetic systems.

Quantum‐Like Dynamics in Whole‐Brain Models of the Human Connectome

Advanced Science, Volume 13, Issue 51, 14 September 2026.
Quantum‐like dynamics in the human brain. The level of quantum‐like behavior in a non‐quantum system of coupled oscillators is regulated by the spectral gap of the coupling graph. Whole‐brain modelling using QL fits the empirical data significantly better and has a lower model‐derived energy cost than the non‐QL model.

Coupled Dynamics Between Networks and Fields in Physical Space: A Theoretical Perspective

Annalen der Physik, Volume 538, Issue 9, September 2026.
Networks embedded in physical space often communicate through dynamical fields that both mediate and respond to collective behavior. A unified theoretical perspective is presented for these network‐field systems, linking established mathematical frameworks and revealing how feedback between discrete interactions and continuous spatial processes can ...

Rising Strong: Cultivating Resilience in Edible City Entrepreneurship. Insights Into the Landscape of Urban Food Initiatives

Business Strategy and the Environment, Volume 35, Issue 6, Page 7728-7742, September 2026.
ABSTRACT In response to growing global challenges, this study explores how social entrepreneurship within the Edible City movement contributes to building resilient, sustainable, and equitable urban food systems. Drawing on semistructured interviews with over 70 stakeholders across five cities—Berlin, Andernach, Oslo, Rotterdam, and Havana—we ...
