A Modified Balanced Steady State Free Precession Sequence for Overhauser Magnetic Resonance Imaging
Magnetic Resonance in Medicine, EarlyView.ABSTRACT Purpose Low‐ and ultralow‐field magnetic resonance imaging (ULF MRI) have inherently low signal‐to‐noise ratio (SNR) by design. Overhauser dynamic nuclear polarization (ODNP) stands out as an effective solution for continuous signal enhancement.

Nordic Journal of Botany, EarlyView.Names in the genus Pinguicula established for taxa from the Baltic and Nordic countries, including their oversea territories and Iceland, were analyzed to provide nomenclatural and taxonomic clarity. Of the 33 names retrieved from the literature and online databases, one is illegitimate, two are invalid and 16 were found to require typification.

Identifying anatomic brain structures using ultra-low field MRI in newborns
NeuroImageBackground: Besides its limitations, cranial ultrasound is the standard imaging method in neonates. Early postnatal magnetic resonance imaging (MRI) offers more objective measurements, but access to MRI is often limited. Portable ultralow-field (ULF) MRI

Negative symbolism of wildlife shapes human–nature coexistence: The plight of owls in Nigeria
People and Nature, EarlyView.Abstract Human–wildlife coexistence in culturally diverse landscapes requires understanding how socio‐cultural processes shape perceptions and behaviours towards conservation‐priority species. This study examines perceptions, belief‐based uses and conservation attitudes towards owls in communities surrounding six Protected Areas in Nigeria, addressing ...

Physik in unserer Zeit, EarlyView.Mit Hilfe der ultrahellen Röntgenpulse des European XFEL und einem speziellen Hochenergielaser konnte die Struktur von flüssigem Kohlenstoff bei Drücken von über einer Million Atmosphären und Temperaturen von etwa 7000 K bestimmt werden. Dieser Ansatz offenbarte eine komplexe Flüssigkeit mit einer wasserähnlichen Struktur und im Mittel vier ...

steel research international, EarlyView.The study investigates the influence of DED‐Arc/M versus casting on the microstructure and material properties of X40CrMoV5‐1 (AISI H13) hot‐work tool steel. DED‐Arc/M yields finer microstructures, superior mechanical strength, and ductility, but slightly reduced thermal conductivity.
