Modeling the High-brightness State of the Recurrent Nova T CrB as an Enhanced Mass-transfer Event

The Astrophysical Journal
T Coronae Borealis is the nearest symbiotic recurrent nova. Twice in the last two centuries, in 1866 and 1946, the accreted material ignited on the surface of the white dwarf via runaway thermonuclear fusion reactions and produced a nova eruption.

Prevalence, Phenotypic Correlates and Predictive Factors of Catatonia in Adolescents With Autism Spectrum Disorder

Journal of Intellectual Disability Research, EarlyView.
ABSTRACT Background Catatonia, a psychomotor syndrome increasingly recognized in individuals with autism spectrum disorder (ASD), remains frequently underdiagnosed due to symptom overlap, particularly in adolescent populations where data remain limited.

A Multiwavelength Study of the Symbiotic Mira HM Sge with SOFIA and HST

The Astrophysical Journal
We have targeted the dusty symbiotic Mira system HM Sge with four instruments from the IR to the UV. We have used these observations along with archival observations to study how the system has been evolving after its 1975 nova-like outburst.

Inflammatory and Immunological Basis of Periodontal Diseases

Journal of Periodontal Research, EarlyView.
The periodontal lesion emerges as an evolving immunological battlefield, where host–microbiome interactions, dysregulated immune responses, fragile resolution mechanisms, and inflammophilic dysbiosis converge to shift the balance from homeostasis to unrestrained tissue destruction.

The period distribution of close binary systems

, 1979
The analysis of the period distribution of eclipsing and spectroscopic binary systems shows the presence of some secondary maxima, which cannot depend on selection effects. These secondary maxima are mainly due to late type stars, as can be seen from the

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.

Shaping the Outflows of Binary AGB Stars

, 2015
The required conditions for stars to evolve into planetary nebulae (PNe) continue to puzzle. Since PNe are found in a wide variety of shapes, processes that could sculpt circumstellar envelopes (CSEs) are being investigated.

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

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).

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 ...
