Type Ia Supernova Progenitors and Surviving Companions within the Symbiotic Channel

The Astrophysical Journal
The symbiotic channel of Type Ia supernovae progenitors is crucial for explaining the observed circumstellar material in some Type Ia supernovae. While extensive numerical and observational efforts have been dedicated to exploring their progenitor ...

One’s loss is (not) another’s gain

Astronomy & Astrophysics
Context. Non-conservative mass transfer plays a central role in close-binary evolution, yet its effects on mass-transfer stability are uncertain. One widely adopted prescription, isotropic re-emission, is often assumed to promote stability, in comparison

Harvesting benefits: Exploring the effects of second‐best policies on enhancing soil organic carbon stocks in agriculture

American Journal of Agricultural Economics, Volume 108, Issue 5, Page 1402-1436, October 2026.
Abstract Agricultural subsidies can be an effective policy tool to enhance soil organic carbon sequestration. This paper assesses the effectiveness of a second‐best hypothetical policy which subsidizes additional canola hectares optimally for each soil zone in Saskatchewan in an effort to increase soil organic carbon.

Monitoring the Dust Emission from R Aqr with SOFIA: Eclipse and Periastron Passage

The Astrophysical Journal
We present infrared (IR) spectra from our monitoring of the symbiotic Mira, R Aquarii, using the Stratospheric Observatory for Infrared Astronomy. New mid-IR photometric and spectroscopic observations using the FORCAST instrument were obtained in 2022 ...

A New Activity Cycle of V1413 Aql

Galaxies
V1413 Aql is an anomalous classical symbiotic star that has remained in an active state almost continuously. After failing to return to quiescence following the 2020 outburst, it underwent a new flare in 2025.

Environmental Regulation at the Crossroads: A Review of Catalysts and Barriers in Circular Economy Transitions

Business Strategy and the Environment, Volume 35, Issue 6, Page 8432-8447, September 2026.
ABSTRACT Amid growing resource pressures, environmental regulation plays a critical role in enabling the transition to a circular economy (CE). This study conducts a systematic literature review to synthesize how different regulatory approaches—command‐and‐control, market‐based, voluntary, and reflexive—affect CE transitions across economic and ...

Mechanistic Insights Into the Association Between Gut Microbiota Diversity and Atherosclerosis, Acute Coronary Syndrome, and Peripheral Arterial Disease Progression

Clinical Cardiology, Volume 49, Issue 9, September 2026.
Proposed gut‐vascular framework linking microbial ecology to atherosclerotic disease. Diet and related exposures shape dysbiosis or microbial resilience; resulting changes in SCFAs, TMAO, bile acids, and LPS may modulate endothelial function, immune activation, and platelet activity, contributing to atherosclerosis, ACS, and PAD.

Binary Parameters for the Recurrent Nova T Coronae Borealis

The Astrophysical Journal
T CrB is among the brightest novae. It is recurrent with outbursts happening approximately every 80 yr. The next outburst is imminent, expected in 2025. The T CrB binary consists of an M4 III red giant (RG) secondary and a white dwarf (WD) primary.

Calibrated Autonomy: China's 2026 Business Mediation Ordinance and the Reconfiguration of Dispute Resolution

Conflict Resolution Quarterly, Volume 44, Issue 1, Page 129-138, Fall 2026.
ABSTRACT This article argues that China's 2026 Business Mediation Ordinance represents neither progress toward rule of law nor retreat from it. I propose instead that we are witnessing something I call “calibrated autonomy”—the strategic construction of spaces for private ordering that remain tethered to Party‐State oversight through multiple ...
