Liver Xenotransplantation: Ethical and Societal Implications

Xenotransplantation, Volume 33, Issue 2, March/April 2026.
ABSTRACT The shortage of transplantable livers and high waitlist mortality rates have accelerated the clinical translation of liver xenotransplantation. Recent milestones, including extracorporeal perfusion models and gene‐edited pig‐to‐human transplants in both decedents and living patients, indicate that clinical trials may be imminent.

Martingales, the efficient market hypothesis, and spurious stylized facts [PDF]

The condition for stationary increments, not scaling, detemines long time pair autocorrelations. An incorrect assumption of stationary increments generates spurious stylized facts, fat tails and a Hurst exponent Hs=1/2, when the increments are ...

Multifractal Hurst Analysis for Identification of Corrosion Type in AISI 304 Stainless Steel

International Journal of Electrochemical Science, 2015
Fractal analysis methods are able to characterize complex time-series and images. In electrochemical corrosion, fractal parameters (fractal dimension, scaling exponent, correlation factors, etc.) have been correlated to the corrosion mechanism, the ...
