Debt Concentration and the Tax Sensitivity of Leverage Concentration de la dette et sensibilité fiscale du levier financier

Contemporary Accounting Research, Volume 43, Issue 2, Page 923-954, Summer 2026.
ABSTRACT A concentrated debt structure can facilitate creditor coordination, which reduces the financial distress cost in a liquidity default but also increases the risk of a strategic default. Debt concentration affects the sensitivity of leverage to tax through these two forces.

Tree‐ring structure determines the temporal coordination between xylem growth and the gain in hydraulic conductivity in the outermost ring

New Phytologist, Volume 250, Issue 6, Page 3732-3746, June 2026.
Summary The study of seasonal xylem hydraulics has predominantly focused on embolism‐induced losses, whereas growth‐driven increases in hydraulic capacity have received little attention. We assessed the intra‐annual dynamics of xylem formation and gain of conductivity in the current‐year ring of three species with contrasting tree‐ring structure ...

Impact of Astaxanthin Concentration in Extender on Sperm Kinetics and Lipid Peroxidation After Cryopreservation in Beef Bulls

Reproduction in Domestic Animals, Volume 61, Issue 6, June 2026.
ABSTRACT Cellular damage caused by changes in temperature and osmolarity during cryopreservation primarily results in excessive generation of reactive oxygen species (ROS). These damages compromise the plasma membrane and reduce sperm fertility. Antioxidants help mitigate these effects.

Annual Variation in Stallion Testicular Measurements and Its Association With Hormonal Profiles and Semen Quality

Reproduction in Domestic Animals, Volume 61, Issue 6, June 2026.
ABSTRACT In a stallion breeding‐soundness examination, testicular volume may be estimated either from total scrotal width or by measuring the height, width and length of both testes. This study aimed to determine whether testicular morphometric parameters obtained by ultrasonography fluctuate throughout the year, and whether these variations affect ...
