First known feeding trace of the eocene bottom-dwelling fish Notogoneus osculus and its paleontological significance.

BACKGROUND: The Green River Formation (early Eocene, about 42-53 Ma) at and near Fossil Butte National Monument in Wyoming, USA, is world famous for its exquisitely preserved freshwater teleost fish in the former Fossil Lake.Nonetheless, trace fossils attributed to fish interacting with the lake bottom are apparently rare, and have not been associa

A Comparative Study of Single-Chain and Multi-Chain MCMC Algorithms for Bayesian Model Updating-Based Structural Damage Detection

Bayesian model updating has received considerable attention and has been extensively used in structural damage detection.It provides a rigorous statistical framework for realizing structural system identification and characterizing uncertainties associated with modeling and measurements.The Markov Chain Monte Carlo (MCMC) is a promising tool for in
