The Debt‐Equity Spread

open access: yesThe Journal of Finance, Volume 81, Issue 4, Page 2005-2062, August 2026.
ABSTRACT We propose a measure of the valuation gap between debt and equity—debt‐equity spread (DES)—based on the difference between actual and equity‐implied credit spreads. DES predicts cross‐sectional stock and bond returns in opposite directions.

Combined phylogenetic and geographic data can predict plant–pest interactions with high accuracy

open access: yesNew Phytologist, Volume 251, Issue 4, Page 2107-2123, August 2026.
Schematic overview of the study pipeline. Summary Non‐native plant pests can pose major threats to biodiversity, with destructive ecological and economic consequences. The ability to predict future threats would allow limited resources to be concentrated on managing the most serious risks. We built a Bayesian model to predict hosts at risk from Agrilus,

Development of a Lensless Compact Optical System for Ultrasensitive Nanomaterial Detection in Liquid Media via Exploiting Multiple Light Scattering

open access: yesNanophotonics, Volume 15, Issue 13, 13 July 2026.
This work presents a lensless speckle‐based platform that exploits multiple light scattering for precise nanoparticle detection in liquid media. The proposed method enables ultrasensitive detection at concentrations far below conventional DLS limits and provides semiquantitative size estimation, offering a cost‐effective and field‐deployable approach ...

Pricing Fractal Derivatives under Sub-Mixed Fractional Brownian Motion with Jumps

open access: yes
We study the pricing of derivative securities in financial markets modeled by a sub-mixed fractional Brownian motion with jumps (smfBm-J), a non-Markovian process that captures both long-range dependence and jump discontinuities. Under this model, we derive a fractional integro-partial differential equation (PIDE) governing the option price dynamics ...
