Mass Transfer in Mira-Type Binaries

Open Astronomy, 2012
Detached, symbiotic binaries are generally assumed to interact via Bondi-Hoyle-Littleton (BHL) wind accretion. However, the accretion rates and outflow geometries that result from this mass-transfer mechanism cannot adequately explain the observations of

Downdraft influences on the differences of PM2.5 concentration: insights from a mega haze evolution in the winter of northern China

Environmental Research Letters, 2023
A significant haze event occurred in northern China from 16 to 21 November 2022. This study analyzed the haze spatial evolution, and meteorological influences by integrating ground and satellite measurements.

Ubiquitous equatorial accretion disc winds in black hole soft states [PDF]

, 2012
High-resolution spectra of Galactic black holes (GBHs) reveal the presence of highly ionized absorbers. In one GBH, accreting close to the Eddington limit for more than a decade, a powerful accretion disc wind is observed to be present in softer X-ray ...

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

FEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Observations of atmospheric gravity waves using airglow all-sky CCD imager at Cachoeira Paulista, Brazil (23° S, 45° W) [PDF]

Geofísica Internacional, 2004
An all-sky CCD imager for OH, O2 and OI (557.7 nm) airglow was operated at Cachoeira Paulista (CP), Brazil, (23° S, 45° W), from October 1998 to September 1999, with Utah State University.

Stellar Mass Loss-Driven Wind Models of Elliptical Galaxies?

, 1994
Recent claims in the literature (Bressan, Chiosi & Fagotto 1994) that the epoch describing the onset of galactic winds in spheroidal star systems has been severely overestimated in the past, due to the neglect of energy deposited in the interstellar ...

Dynamics of Line-driven Disk Winds in Active Galactic Nuclei. II. Effects of Disk Radiation [PDF]

, 2000
We explore consequences of a radiation-driven disk wind model for mass outflows from active galactic nuclei (AGNs). We performed axisymmetric time-dependent hydrodynamic calculations using the same computational technique as Proga, Stone, and Kallman. We

The human gut microbiome across the life course

FEBS Letters, EarlyView.
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

Peering Inside Tropical Cyclones With the WIVERN Space‐Borne Doppler Radar

Earth and Space Science
The WIVERN (Wind Velocity Radar Nephoscope) mission significantly enhances the global tropical cyclone observing system. Operating from a 500 km near‐polar orbit, the 3 m diameter conically scanning antenna provides an 800 km swath. The radar operated at
