Neonatal Nutrition and Brain Structure at 7 Years in Children Born Very Preterm.
JAMA Netw Open
January 2025
Liggins Institute, University of Auckland, Auckland, New Zealand.
Importance: Neonatal protein intake following very preterm birth has long lasting effects on brain development. However, it is uncertain whether these effects are associated with improved or impaired brain maturation.
Objective: To assess the association of neonatal protein intake following very preterm birth with brain structure at 7 years of age.
Interfacial Strain-Driven Large Topological Hall Effects in Supermalloy Thin Films with Noncoplanar Spin Textures.

Materials exhibiting topological transport properties, such as a large topological Hall resistivity, are crucial for next-generation spintronic devices. Here, we report large topological Hall resistivities in epitaxial supermalloy (NiFeMo) thin films with [100] and [111] orientations grown on single-crystal MgO (100) and AlO (0001) substrates, respectively. While X-ray reciprocal maps confirmed the epitaxial growth of the films, X-ray stress analyses revealed large residual strains in the films, inducing tetragonal distortions of the cubic NiFeMo unit cells.

Two-dimensional (2D) layered materials have received much attention due to the unique properties stemming from their van der Waals (vdW) interactions, quantum confinement, and many-body interactions of quasi-particles, which drive their exotic optical and electronic properties, making them critical in many applications. Here, we review our past years' findings, focusing on many-body interactions in 2D layered materials, including phonon anharmonicity, electron-phonon coupling (), exciton dynamics, and phonon anisotropy based on temperature (polarization)-dependent Raman spectroscopy and Photoluminescence (PL). Our review sheds light on the role of quasi-particles in tuning the material properties, which could help optimize 2D materials for future applications in electronic and optoelectronic devices.

College of Chemistry, Sichuan University, Chengdu 610065, P. R. China.
We present two novel antimony(III)-based tellurite sulfate crystals, Sb(TeO)(SO)-1̅ (I) and Sb(TeO)(SO)-2/ (II), synthesized using a dual lone pair strategy that incorporates Sb and Te ions into a sulfate framework. This approach significantly enhances the birefringence of these compounds, with values of 0.11 and 0.

Purpose: Astigmatism can lead to meridional amblyopia, an orientation-specific visual deficit. This study investigated the effects of astigmatism on meridional anisotropy in contrast sensitivity (CS) and steady-state visual evoked potential (ssVEP) across a range of spatial frequencies.
Methods: Thirty-two young adults with a best-corrected distance visual acuity of logMAR 0 or better were categorized into two groups: highly astigmatic (HAS, = 16) with spherical-equivalent error (SE) ≥ -6.
