A compatibility criterion for optimal control and information aggregation in hierarchical network systems

open access: yesAsian Journal of Control, Volume 28, Issue 4, Page 1722-1733, July 2026.
Abstract Large swarms often adopt a hierarchical network structure that incorporates information aggregation. Although this approach offers significant advantages in terms of communication efficiency and computational complexity, it can also lead to degradation due to information constraints.

Group Differences of Multiregion Glutamate Concentration in Clinical High Risk and Schizophrenia

open access: yesEuropean Journal of Neuroscience, Volume 64, Issue 1, July 2026.
We investigated group effects of glutamate concentrations in 99 participants in four brain regions using proton magnetic resonance spectroscopy in clinical high risk, schizophrenia spectrum psychotic disorder individuals and healthy controls. Results showed no significant group differences, exploratory analyses showed significant positive symptom ...

DC Side Impedance Modelling of an Actual Line Commutated Converter High Voltage Direct Current System and DC Resonance Characteristics

open access: yesHigh Voltage, Volume 11, Issue 3, Page 725-737, June 2026.
ABSTRACT The stability analysis of Line Commutated Converter High Voltage Direct Current (LCC‐HVDC) is of considerable engineering importance. Establishing its analytical mathematical model helps to analyse stability and the factors that affect stability of the system.

Toeplitz Operators on Abstract Hardy Spaces Built upon Banach Function Spaces

open access: yesJournal of Function Spaces, 2017
Let X be a Banach function space over the unit circle T and let H[X] be the abstract Hardy space built upon X. If the Riesz projection P is bounded on X and a∈L∞, then the Toeplitz operator Taf=P(af) is bounded on H[X].

Next Generation 7 Tesla Arterial Spin Labeling With Rotated Spiral Acquisition Enables Mesoscale Resolution in 3D Brain Perfusion and Functional MRI

open access: yesMagnetic Resonance in Medicine, Volume 95, Issue 5, Page 2702-2717, May 2026.
ABSTRACT Purpose To achieve high resolution (≤ 1 mm isotropic) whole‐brain perfusion imaging at 7 T with next generation ASL pulse sequence, reconstruction algorithm, and MRI hardware. Methods We capitalized on three major innovations: (1) FLASH‐based pseudo‐Continuous ASL (pCASL) sequence with rotated golden‐angle stack‐of‐spirals (rGA‐SoS) sampling; (

Toeplitz Operators on Weighted Bergman Spaces

open access: yesJournal of Function Spaces and Applications, 2013
We characterize the boundedness and compactness of a Toeplitz-type operator on weighted Bergman spaces satisfying the Bekollé-Bonami condition in terms of the Berezin transform.

Hyponormality on a Weighted Bergman Space

open access: yesJournal of Function Spaces, 2020
A bounded Hilbert space operator T is hyponormal if T∗T−TT∗ is a positive operator. We consider the hyponormality of Toeplitz operators on a weighted Bergman space.
