Political Connections, Subsidized Loans, and Capital Markets Development

Kyklos, EarlyView.
ABSTRACT This paper analyzes the relationship between political connections and firms' financing decisions in Brazil using large datasets on campaign contributions, loans from the Banco Nacional de Desenvolvimento Econômico e Social (BNDES), and financial variables from Capital IQ.

Symbiotic Stars (Including T Corona Borealis) Are Not Immediate Progenitors of Normal Type Ia Supernovae

The Astrophysical Journal
A popular solution to the Type Ia supernova (SN Ia) progenitor problem is that the immediate progenitors are symbiotic star systems. This solution requires that the companion star of the exploding white dwarf must be a red giant star with a heavy stellar

Intraspecific variation in an arbuscular mycorrhizal fungus affects a plant and an AMF community

New Phytologist, EarlyView.
Mesocosm placement within the growing facility. Summary Arbuscular mycorrhizal fungi (AMF) show substantial genetic, trait, and functional variation within species. Whether this intraspecific variability has community‐level consequences for plant and AMF communities is unclear.

Revisiting atmospheric Roche-lobe overflow in symbiotic binaries

Astronomy & Astrophysics
Context. Classical binary evolution models predict dynamically unstable mass transfer in symbiotic stars with high mass ratios (qcrit > 1.6), leading to a common envelope (CE).

The Symbiotic X-Ray Binary IGR J16194-2810: A Window on the Future Evolution of Wide Neutron Star Binaries From Gaia

Publications of the Astronomical Society of the Pacific
Abstract We present optical follow-up of IGR J16194-2810, a hard X-ray source discovered by the INTEGRAL mission. The optical counterpart is a ∼500 L ⊙ red giant at a distance of 2.1 kpc. We measured 17 radial velocities (RVs) of the giant over a period of 271 days.

Rice Orange Leaf Phytoplasma Imp Protein Blocks G–M Interaction by Binding Glycoprotein G to Suppress Rice Stripe Mosaic Virus Infection

Plant, Cell &Environment, EarlyView.
ABSTRACT Plants frequently encounter multiple pathogens concurrently, yet the molecular bases of pathogen–pathogen interactions during mixed infections remain largely unresolved. Here we show that co‐infection of rice by Rice orange leaf phytoplasma (ROLP) and Rice stripe mosaic virus (RSMV) markedly suppresses RSMV proliferation in both host plants ...

On Its Way to the Neutron Star–White Dwarf Binary Graveyard, IGR J16194−2810, A First Ascent M Giant X-Ray Binary

The Astrophysical Journal
A single-lined spectroscopic orbit for the M giant in the X-ray binary IGR J16194−2810 is determined from a time series of optical spectra. The spectroscopic orbital period of 192.5 days is twice that of the photometric period, confirming that the M ...

Periodontitis and metabolic dysfunction‐associated steatotic liver disease

Periodontology 2000, EarlyView.
Abstract Objective Periodontitis is a chronic inflammatory disease with systemic effects that extend beyond the oral cavity and contribute to systemic immune and metabolic dysregulation. Chronic liver diseases, particularly metabolic dysfunction‐associated steatotic liver disease (MASLD) and its progressive phenotypes, have emerged as major global ...

Symbiotic Stars as Laboratories for the Study of Accretion and Jets: A Call for Optical Monitoring

, 2003
Symbiotic binary stars typically consist of a white dwarf (WD) that accretes material from the wind of a companion red giant. Orbital periods for these binaries are on the order of years, and their relatively small optical outbursts tend to occur every ...
