Elemental abundances in AGB stars and the formation of the Galactic bulge

EPJ Web of Conferences, 2012
We obtained high-resolution near-IR spectra of 45 AGB stars located in the Galactic bulge. The aim of the project is to determine key elemental abundances in these stars to help constrain the formation history of the bulge.

Discovery of Millisecond Pulsars toward the Galactic Bulge in an Image-based Survey with MeerKAT

The Astrophysical Journal
We report on the follow-up observations of circularly polarized sources identified in the MeerKAT image-based survey of the Galactic bulge. Using the Parkes radio telescope, we observed 16 circularly polarized sources with the Ultra-Wideband Low receiver

A Review of Failure Modes and Safety Strategies of Lithium‐Ion Batteries from Materials to Systems

Advanced Science, Volume 13, Issue 42, 28 July 2026.
A cascade‐aware framework is presented for lithium‐ion battery safety, linking thermal runaway initiation, acceleration, runaway reaction, and propagation with material‐, cell/pack‐, and system‐level interventions. By integrating failure mechanisms, quantitative safety indicators, and staged interception strategies, this review highlights how safer ...

Emergent Spin Fluctuation and Structural Metastability in Self‐Intercalated Cr1+xTe2${\rm Cr}_{1+x}{\rm Te}_2$ Compounds

Advanced Electronic Materials, Volume 12, Issue 13, 6 July 2026.
Metastable superstructure and emergent spin fluctuation in self‐intercalated Cr1+xTe2${\rm Cr}_{1+x}{\rm Te}_2$ ABSTRACT Intercalated van der Waals (vdW) magnetic materials host unique magnetic properties due to the interplay of competing interlayer and intralayer exchange couplings, which depend on the intercalant concentration within the van der ...

A thorny evolution: first Triassic ammonoid with a ventral apertural elongated rostrum

Papers in Palaeontology, Volume 12, Issue 4, July/August 2026.
Abstract Ornamented terminal peristomes are common in ammonoids, but pronounced conch projections are rare, particularly in the Triassic. A new early Spathian assemblage from southeastern Idaho yielded two ammonoid specimens with an impressive terminal mid‐ventral elongated rostrum, documenting the first Triassic occurrence and one of the few ...
