Reconfigurable Geometric Phase Matching by Multilayered Nonlinear Thin‐Film Crystals
Laser &Photonics Reviews, EarlyView.The concept of geometric phase matching is demonstrated as a dynamically reconfigurable approach for tunable nonlinear wave mixing in multilayered nonlinear thin‐film crystals. Experimental results reveal full modulation in a bilayer structure and near‐perfect spin‐selective phase matching of second‐harmonic generation in an eight‐layer configuration ...

A Triple Scenario for the Formation of Wide Black Hole Binaries Such as Gaia BH1
The Astrophysical JournalRecently, several noninteracting black hole–stellar binaries have been identified in Gaia data—for example, Gaia BH1, where a Sun-like star is in a moderately eccentric ( e = 0.44) 185 days orbit around a black hole.

Subdwarf B Stars: Tracers Of Binary Evolution [PDF]
, 2007 Contains fulltext : 36520.pdf (Author’s version preprint ) (Open Access)Subdwarf B stars are a superb stellar population to study binary evolution. In 2001, Maxted et al.

PROTEOMICS, EarlyView.ABSTRACT Zoonotic infections caused by influenza A viruses (IAVs) of animal origin are a major public health concern, as they may represent the initial step toward the emergence of a pandemic strain. The host range of IAVs is shaped by species‐specific virus‐host interactions, and several host barriers have been identified that restrict the adaptation ...

Tales of stellar and binary coevolution, told by stellar oscillations
Astronomy & AstrophysicsContext. Red giants are increasingly used as stellar population tracers due to their well-understood evolution and the availability of asteroseismic observables. However, stellar binarity can alter observable properties and introduce strong biases. Aims.

Phytotherapy Research, EarlyView.ABSTRACT Vascular dementia (VaD), accounting for up to 20% of dementia cases globally, is primarily driven by chronic cerebral hypoperfusion (CCH), which leads to progressive cognitive impairment. Despite the increasing prevalence of VaD, effective treatments remain limited.

Post-common-envelope planetary nebulae
Close-binary central stars of planetary nebulae offer a unique tool with which to study the critical and yet poorly understood common-envelope phase of binary stellar evolution. Furthermore, as the nebula itself is thought to comprise the ionised remnant

The Fate of Gaia’s Wide Binaries: Interplay of White-dwarf Recoil and Tidal Interactions
The Astrophysical JournalWhite dwarfs (WDs) receive natal velocity boosts of ∼1 km s ^−1 due to recoil from asymmetric mass loss during the late asymptotic giant branch (AGB) stage.

Astronomy & AstrophysicsContext. Eclipsing close double white dwarf (WD) systems, by providing precise radii and masses, offer a unique opportunity to directly constrain hydrogen-envelope (MH) retention and test common-envelope (CE) evolution in low-mass stars. Aims. We analyse

Nowcasting convective cores using deep learning
Quarterly Journal of the Royal Meteorological Society, EarlyView.Key findings: •$$ \bullet $$ Network for Nowcasting Convective Cores (NetNCC) has considerable potential for convective storm nowcasting and the development of early warning systems for extreme rainfall. •$$ \bullet $$ Skilful nowcasts of convective cores are obtained at fine spatial resolutions (<30km$$ <30\kern0.15em \mathrm{km} $$) for up to 2 hr ...
