Reproducibility of tailored and universal nonselective excitation pulses at 7 T for human cardiac MRI: A 3‐year and an interday study

open access: yesMagnetic Resonance in Medicine, Volume 94, Issue 2, Page 588-601, August 2025.
Abstract Purpose Ultrahigh‐field (UHF; ≥7 T) MRI is challenging due to spatially heterogeneous B1+ profiles. This longitudinal study evaluates the reproducibility of three parallel‐transmission excitation strategies to enable UHF cardiac MRI: vendor‐supplied radiofrequency (RF) shim, subject‐tailored kT‐points pulses (TPs), and universal kT‐points ...

Solving Large‐Scale Weapon Target Assignment Problems in Seconds Using Branch‐Price‐And‐Cut

open access: yesNaval Research Logistics (NRL), Volume 72, Issue 5, Page 735-749, August 2025.
ABSTRACT This paper proposes a framework based on branch‐price‐and‐cut to solve the weapon target assignment (WTA) problem, a popular class of non‐linear assignment problems that has received significant attention over the past several decades. We first reformulate the WTA into a form amenable to column generation and then derive efficient algorithms ...

Confining Surface Oxygen Redox in Double Perovskites for Enhanced Oxygen Evolution Reaction Activity and Stability

open access: yesAdvanced Energy Materials, Volume 15, Issue 25, July 1, 2025.
The double perovskite BaSrNiWO6 is developed as an oxygen evolution reaction catalyst. B‐site W6+ dissolution drives in situ reconstruction of the surface to a disordered, NiO‐like layer. Consequently, local oxygen species are activated for a surface lattice oxygen evolution mechanism (sLOEM).

On the Brink: Mapping the Last Strongholds of the Critically Endangered Flapper Skate (Dipturus intermedius)

open access: yesEcology and Evolution, Volume 15, Issue 7, July 2025.
This study presents a high‐resolution spatial distribution model for the Critically Endangered flapper skate (Dipturus intermedius) across the NE Atlantic shelf, integrating environmental and fishing pressure data. Results highlight three core regions of presence off the coasts of Scotland and western Ireland, likely reflecting natural refugia and the ...

Potassium‐Dependent Coupling of Retinal Astrocyte Light Response to Müller Glia

open access: yesGlia, Volume 73, Issue 7, Page 1520-1534, July 2025.
Main Points Astrocytes depolarize to light ON and OFF like Müller glia. The astrocyte light response is due to potassium influx. Retinal macroglial current‐voltage responses exhibit rectification which changes with repeated stimulation. ABSTRACT Astrocytes throughout the central nervous system mediate a variety of functions to support proper tissue ...
