X-Rays from RS Ophiuchi’s 2021 Eruption: Shocks In and Out of Ionization Equilibrium

The Astrophysical Journal
The recurrent nova RS Ophiuchi (RS Oph) underwent its most recent eruption on 2021 August 8 and became the first nova to produce both detectable GeV and TeV emission.

Caveolin‐1 enriched apoptotic bodies derived from oral hard palate orchestrate bone remodeling to treat heterotopic ossification

BMEMat, EarlyView.
Downregulated CAV1 in HO is restored via apoptotic bodies from PMSCs, which reprogram bone remodeling by delivering CAV1 to target cells, highlighting the therapeutic role of EV subtypes in heterotopic ossification. Abstract Heterotopic ossification (HO) is a pathological process characterized by ectopic bone formation in non‐osseous tissues, with an ...

The Accelerating Decline of the Mass Transfer Rate in the Recurrent Nova T Pyxidis

The Astrophysical Journal
The recurrent nova T Pyxidis (T Pyx) has erupted six times since 1890, with its last outburst in 2011, and the relatively short recurrence time between classical nova explosions indicates that T Pyx must have a massive white dwarf (WD) accreting at a ...

Hot and cold deserts as eco‐evolutionary arenas for understanding plant resistance to multiple abiotic stressors

Biological Reviews, EarlyView.
ABSTRACT During their long evolutionary history, land plants have evolved a range of adaptations to different abiotic stressors. These help explain present‐day diversity and distribution patterns, as well as the potential resilience of natural and agricultural systems to a changing climate. Most previous research has focused on adaptation to individual

Multiwavelength Observations of Multiple Eruptions of the Recurrent Nova M31N 2008-12a

The Astrophysical Journal
We report the optical, UV, and soft X-ray observations of the 2017–2022 eruptions of the recurrent nova M31N 2008-12a. We find a cusp feature in the $r^{\prime} $ - and $i^{\prime} $ -band light curves close to the peak, which could be related to jets ...

From Vulnerability to Resilience: Dynamic Capabilities as a Moderating Mechanism Under Environmental Turbulence in Developing Economies

Business Strategy and the Environment, EarlyView.
ABSTRACT SMEs in developing economies operate under persistently volatile environments where economic instability, regulatory uncertainte and technological disruptions threaten their survival. Here, sustainability shifts from long‐term environmental or socioeconomic performance to strategic resilience.

Lack of Significant Orbital-phase Locking in the Active Phases of the Recurrent Nova T CrB

The Astrophysical Journal
T Coronae Borealis (T CrB) is a symbiotic recurrent nova that exhibits both nova eruptions and long-term active phases resembling superoutbursts and normal outbursts.
