The Fractional Ornstein-Uhlenbeck Process: Term Structure Theory and Application [PDF]
The paper revisits dynamic term structure models (DTSMs) and proposes a new way in dealing with the limitation of the classical affine models. In particular, this paper expands the flexibility of the DTSMs by applying a fractional Brownian motion as the ...

NARFL Knockout Triggers Ferroptosis‐Driven Vascular Endothelial Dysfunction
Advanced Science, EarlyView.NARFL is vital for CIA and oxidative stress resistance. NARFL deletion in HPMEC cells, zebrafish, and mice is lethal and rescued by a Ferroptosis inhibitor. NARFL deficiency disrupted its interaction with CIA proteins, decreased aconitase activity, increased IRP1 activity, induced Fe overload, and led to ferroptosis and oxidative stress, resulting in ...

Investment Timing, Liquidity, and Agency Costs of Debt [PDF]
This paper examines the effect of debt and liquidity on corporate investment in a continuous- time framework. We show that stockholder-bondholder agency conflicts cause investment thresholds to be U-shaped in leverage and decreasing in liquidity.

Bioinspired Twisted Artificial Muscles with Enhanced Performance for Underwater Applications
Advanced Science, EarlyView.A climbing plant‐inspired twisted artificial muscle (TAM) with a braided configuration and seal‐inspired thermal insulation enables high‐performance underwater actuation. Enhanced deformation, reduced heat dissipation, and rapid motion are validated through a bionic ray that exhibits straight and turning motions.
