Are markets adaptive? Evidence of predictability and market efficiency of lodging/resort REITs
International Journal of Strategic Property Management, 2020 We investigate the degree of return predictability of lodging/resort real estate investment trusts (REITs) from January 1994 to May 2016. We test the Martingale hypothesis by using linear (automatic portmanteau and automatic variance ratio with rolling ...

Market Efficiencies and Market Risks [PDF]
SSRN Electronic Journal, 2010 In recent years numerous papers constructed or simulated financial markets at an agent level, aiming to explain the non-stationarity of price processes. All such papers agree that the heterogeneity of agents and of pricing models creates a dynamics in terms of pricing models used that explains not only the non-stationarity of price processes, but also ...

Bioprinting High‐Cell‐Density Cardiac Tissue Constructs With Sustained Contractile Function
Advanced Healthcare Materials, EarlyView.Contractile cardiomyocytes in 3D culture provide insights into the behavior of the heart. Combining a 3D bioprinting approach with a multi‐electrode array allows the development of the 3D culture to be monitored over time, and matured cultures allow the effect of drugs on cardiac function to be modelled, replicating effects seen in clinical application.
