Electric Field Modulation of Interlayer Coupling via Piezostrain in a Synthetic Antiferromagnet
Advanced Science, EarlyView.Controlling the interlayer exchange coupling (IEC) in synthetic antiferromagnets (SAFs) using an electric field is a promising route toward energy‐efficient spintronic devices. In this study, electric field induced‐strain modulation of IEC in Co/Ru/Co SAF/PMN‐PT is demonstrated.

The blue stragglers of Omega Centauri
The Astrophysical Journal, 1986 On a obtenu les spectres 3500-5000 A (resolution 3,6 A) de six candidats. Ils ne presentent aucune caracteristique inhabituelle. les vitesses radiales montrent que ces six vagabondes bleues appartiennent a l'amas.

Advanced Intelligent Systems, EarlyView.This study presents a compact freeform projection optics using dual wedge prisms for waveguide displays. Unlike previous designs that separate illumination and imaging paths, a freeform optical path integrates both. The system achieves a 32º field of view, 37.5 pixels per degree, and a total volume of less than 2 cm3.

Identification of Blue Horizontal-branch Stars Using Synthetic SkyMapper Colors from Gaia XP Spectra
The Astrophysical Journal Supplement SeriesBlue horizontal-branch (BHB) stars are ideal tracers for mapping the structure of the Galactic stellar halo. Traditionally, BHB sample stars are built from large-scale spectroscopic surveys utilizing their spectral features; however, the resulting sample

Hidden Figures of Globular Clusters: Integrated Stellar Populations Impacted by Hot Subdwarfs
The Astrophysical JournalGlobular clusters (GCs) are fundamental for understanding the integrated light of old stellar populations and galaxy assembly processes. However, the role of hot, evolved stars, such as horizontal branch (HB), extreme HB, and blue stragglers, remains ...

Angewandte Chemie International Edition, EarlyView.Rapid RASER MRI allows for image acquisition without RF excitation. Instead, a population inversion on the nuclear spins is generated by SABRE hyperpolarization, which allows for self‐excitation through the RASER approach. When the desired transverse magnetization is built‐up, conventional EPI encoding is triggered to record the image.
