Non‐Invasive Auricular Vagus Nerve Stimulation Decreases Heart Rate Variability Independent of Caloric Load

open access: yesPsychophysiology, Volume 62, Issue 2, February 2025.
Impact statement Heart rate variability, measured by HF‐HRV and RMSSD, is conventionally used to index cardiac vagal activity. Our study demonstrates that transcutaneous auricular vagus nerve stimulation (taVNS) decreases HRV indexed by SDRR, RMSSD, and HF‐HRV irrespective of the side of stimulation, contradicting a link to heightened cardiac vagal ...

Automated detection of an insect‐induced keystone vegetation phenotype using airborne LiDAR

open access: yesMethods in Ecology and Evolution, Volume 15, Issue 5, Page 978-993, May 2024.
Abstract Ecologists, foresters and conservation practitioners need ‘biodiversity scanners’ to effectively inventory biodiversity, audit conservation progress and track changes in ecosystem function. Quantifying biological diversity using remote sensing methods remains challenging, especially for small invertebrates.

Credit Calibration with Structural Models: The Lehman case and Equity Swaps under Counterparty Risk

open access: yes, 2009
In this paper we develop structural first passage models (AT1P and SBTV) with time-varying volatility and characterized by high tractability, moving from the original work of Brigo and Tarenghi (2004, 2005) [19] [20] and Brigo and Morini (2006)[15].

On the mathematical form of CVA in Basel III. [PDF]

open access: yes
Credit valuation adjustment in Basel III is studied from the perspective of the mathematics involved. A bank covers mark-to-market losses for expected counterparty risk with a CVA capital charge. The CVA is known as credit valuation adjustments.

How Integrated are Credit and Equity Markets? Evidence from Index Options

open access: yesThe Journal of Finance, Volume 79, Issue 2, Page 949-992, April 2024.
ABSTRACT We study the extent to which credit index (CDX) options are priced consistent with S&P 500 (SPX) equity index options. We derive analytical expressions for CDX and SPX options within a structural credit‐risk model with stochastic volatility and jumps using new results for pricing compound options via multivariate affine transform analysis.
