Active Electromagnetic Interference Suppression for MRI and Proton Resonance Frequency Shift Thermometry During MRI‐Guided Microwave Ablation

Magnetic Resonance in Medicine, Volume 96, Issue 4, Page 1572-1588, October 2026.
ABSTRACT Purpose To develop a software‐based active electromagnetic interference (EMI) suppression (AES) framework on whole‐body multi‐channel MRI systems for reliable MRI and MR thermometry during MRI‐guided microwave ablation (MWA). Methods In addition to primary imaging coils, an unloaded standard body array coil was positioned outside the imaging ...

Topologizability and Power Boundedness of Convolutions and Toeplitz Operators on Power Series Spaces [PDF]

We characterize the topologizability and power boundedness of convolution and dual convolution operators on power series spaces.We determine necessary conditions for a Toeplitz operator to be m-topologizable, and power bounded on 1(n) and ∞(n), and ...

Rational reductions of the 2D-Toda hierarchy and mirror symmetry [PDF]

, 2017
International audienceWe introduce and study a two-parameter family of symmetry reductions of the two-dimensional Toda lattice hierarchy, which are characterized by a rational factorization of the Lax operator into a product of an upper diagonal and the ...

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

Asian 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

European 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 ...

Painlevé tau-functions and Fredholm determinants [PDF]

, 2021
It is now known that the tau-functions associated to the generic solutions of the Painlevé equations III, V, VI can be expressed as a Fredholm determinants. The minor expansion of these determinants provide an interesting connection to random partitions.

Skew-Commuting Toeplitz Operators and Dual Toeplitz Operators on Bergman Spaces

Mathematics
We study the skew-commutativity of Toeplitz operators and dual Toeplitz operators on the Bergman space of the unit disk. For bounded harmonic symbols, we characterize when two Toeplitz operators are skew-commuting. For general bounded measurable symbols, we give necessary and sufficient conditions for the skew-commutativity of dual Toeplitz operators ...

Properties of Commutativity of Dual Toeplitz Operators on the Orthogonal Complement of Pluriharmonic Dirichlet Space over the Ball [PDF]

Journal of Function Spaces, 2016
We completely characterize the pluriharmonic symbols for (semi)commuting dual Toeplitz operators on the orthogonal complement of the pluriharmonic Dirichlet space in Sobolev space of the unit ball. We show that, forfandgpluriharmonic functions,SfSg=SgSfon(Dh)⊥if and only iffandgsatisfy one of the following conditions:(1)bothfandgare holomorphic;(2 ...
