Journal of Microscopy, EarlyView.Abstract In the domain of battery research, the processing of high‐resolution microscopy images is a challenging task, as it involves dealing with complex images and requires a prior understanding of the components involved. The utilisation of deep learning methodologies for image analysis has attracted considerable interest in recent years, with ...

Read My Leads: Subject‐Specific RF Hazard Assessment and Mitigation for DBS Implants in MRI
Magnetic Resonance in Medicine, Volume 95, Issue 4, Page 2316-2330, April 2026.ABSTRACT Purpose To develop and validate a framework for personalized, implant‐specific MRI safety assessments using feedback from commercial deep brain stimulation (DBS) systems. To further use this framework to suppress RF‐induced heating with minimum compromise in imaging performance.

Physical Review Research, 2020 We study entanglement properties of free-fermion systems without Hermiticity by use of correlation matrix and overlap matrix in the biorthogonal basis. We find at a critical point in the non-Hermitian Su-Schrieffer-Heeger (SSH) model with parity and time-

Brain Pulsation Imaging Using Non‐Balanced Steady‐State Free Precession With 3D‐EPI Readout
Magnetic Resonance in Medicine, Volume 95, Issue 3, Page 1606-1618, March 2026.ABSTRACT Purpose To present a new, fast MR imaging method for visualization and quantification of pulsatile displacement in brain tissue and fluid. Methods The natural phase‐contrast of non‐balanced steady‐state free precession combined with careful tuning of the intrinsic spoiler gradients is harnessed to measure displacement along specific physical ...

Simple subspace based adaptive beamforming under Toeplitz covariances
EURASIP Journal on Advances in Signal ProcessingWhen uncorrelated signals are incident on a uniform linear array, the array covariance matrix is of the Toeplitz form. An adaptive beamforming method is proposed based on the signal-plus-interference (SI) subspace via the Toeplitz rectification of the ...

Band‐Selective IR PRESS for Brain Tumor Spectroscopy Allows Robust Detection of Lactate
NMR in Biomedicine, Volume 39, Issue 3, March 2026.Lactate quantification by MRS is hindered by lipid signal overlap at 1.3 ppm, frequently forcing the use of long echo times that suppress other metabolites. We developed SPIR‐PRESS, a selective inversion recovery technique that suppresses lipids while preserving metabolite sensitivity.

Generalized unitary evolution for symplectic scalar fermions
Journal of High Energy PhysicsThe theory of symplectic scalar fermion of LeClair and Neubert is studied. The theory evades the conventional spin-statistics theorem because its Hamiltonian is pseudo Hermitian. The definition of pseudo Hermiticity is examined in the interacting and the

International Journal of Mathematics and Mathematical Sciences, 2012 We establish necessary and sufficient conditions for the existence of and the expressions for the general real and complex Hermitian solutions to the classical system of quaternion matrix equations A1X=C1,XB1=C2, and A3XA3*=C3. Moreover, formulas of the
