This book was written by many outstanding investigators who have spent decades to study different aspects of blood-tissue barrier function. They have summarized some of the latest and fascinating development in their fields of research including the blood-brain barrier, the blood-retinal barrier, the gut barrier, the blood-biliary barrier, the blood-follicle barrier, the blood-epididymis barrier, the blood-testis barrier, the tight junction barrier in general as well as barriers in the female reproductive tract. Included are also chapters that focus on topics that are physiologically applicabl

AbstractWe question time‐invariant indices as fund benchmarks and propose a regime‐switching methodology to identify time‐varying de facto benchmarks from a pool of market‐based indices, with or without a risk‐free asset. To ameliorate the benchmark mismatch issue, we highlight the importance of using time‐varying indices‐based benchmarks for fund performance evaluation. Our de facto benchmark captures fund styles better than other benchmark choices, substantially improves the identification of significant fund alphas, and provides better out‐of‐sample forecasts. We uncover several new findings in terms of fund performance evaluation using our de facto benchmarks.
