Magnetic Resonance in Medicine, Volume 95, Issue 3, Page 1513-1527, March 2026.ABSTRACT Purpose Pediatric craniofacial imaging may involve examination of both the skull and brain tissues via CT and MRI, respectively. DREAMER (Dual Repetition and Echo Acquisition with Multi‐contrast Encoding and Reconstruction) simultaneously acquires solid‐ and soft‐tissue images, potentially providing a rapid, high‐resolution, and radiation‐free

Stability and Instability of Time‐Domain Boundary Element Methods for the Acoustic Neumann Problem
Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 1, March 2026.ABSTRACT This work presents a stable time‐domain boundary element method for the acoustic wave equation in three‐dimensional unbounded domains. Other formulations of time‐domain boundary element methods based on retarded potential operators are known to exhibit stability issues, which often hinder their use in industrial contexts.

Sifat Topologi dan Relasidualk¨ Othe-T¨ Oeplitz dari Generalisasi Ruang Barisan Bernilai vector yang didefinisikan oleh fungsi-' [PDF]
, 2018 Sequence space and its dual relation is one of the major issues in research in the field of mathematical analysis. The newfangling in the sequence space has been done by Kothe-Toeplitz (1934) through the dual concept which came to be known by the dual ...

On moments of the derivative of CUE characteristic polynomials and the Riemann zeta function
Journal of the London Mathematical Society, Volume 113, Issue 3, March 2026.Abstract We study the derivative of the characteristic polynomial of N×N$N \times N$ Haar‐distributed unitary matrices. We obtain new explicit formulae for complex‐valued moments when the spectral variable is inside the unit disc, in the limit N→∞$N \rightarrow \infty$.

Steady‐State Spread Bounds for Graph Diffusion via Laplacian Regularisation in Networked Systems
IET Networks, Volume 15, Issue 1, January/December 2026.We study how an engineered initial pattern on a fixed network blurs under linear diffusion and provide a steady‐state upper bound on the resulting deviation. The bound cleanly separates an unavoidable floor set by network connectivity and diffusion strength from a design‐controlled term that shrinks when the initial pattern is smoothed with a graph ...

IET Renewable Power Generation, Volume 20, Issue 1, January/December 2026.Core approach: hybrid model combining wake dynamics, spectral clustering and adaptive neighbourhood selection. Methodology: spatial decoupling → representative turbine identification → feature aggregation via memory network. Outcome: enhanced prediction accuracy validated by real‐data comparisons, addressing spatial correlation challenges in wind farms.

Design and Optimization of Finite Alphabet Waveforms for Multiple‐Antenna Radar Covariance Matching
IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.This article propose a novel method for finite‐alphabet waveform generation based on constrained matrix decomposition. It also expands theoretical feasibility bounds for generating covariance matrices with binary waveforms, proves that matrices from autoregressive processes are always realizable and introduces an optimal adjustment procedure for ...

Techniques in operator algebras: classification, dilation and non-commutative boundary theory [PDF]
, 2017 In this thesis we bring together several techniques in the theory of non-self-adjoint operator algebras and operator systems. We begin with classification of non-self-adjoint and self-adjoint operator algebras constructed from C*-correspondence and more ...
