We study a dynamic asset allocation problem in which expected stock returns are predictable, focusing on an investor with a medium-term horizon of up to five years. At these horizons, both return continuation (momentum) and mean-reversion are of central importance in the asset allocation problem. Researchers have extensively investigated the impact of mean-reversion on optimal portfolio choice,...

This paper investigates the combinatorial $\alpha$-curvature for vertex scaling of piecewise hyperbolic metrics on polyhedral surfaces, which is a parameterized generalization classical curvature. A discrete uniformization theorem established, generalizes Gu-Guo-Luo-Sun-Wu’s curvature [J. Differential Geom. 109 (2018), pp. 431–466]. We further introduce $\alpha$-Yamabe flow and $\alpha$-Cal...

This study evaluated the effects of calf management following early weaning (EW) on growth and reproductive performance of beef heifers. On d 0, Brahman x British heifers (n = 40; body weight [BW] = 187 ± 37 lb; age = 69 ± 12 d) were stratified by age and BW, and randomly assigned to be normally-weaned on d 177 (NW), or 1 of 3 EW treatments: (1) EW and grazed on ryegrass pastures for 67 d then ...

Abstract Introduction Acquired vaginal stenosis known as gynetresia has remained more common than the congenital type in developing countries where women engage all manner of harmful practices including insertion corrosives into vagina, female genital mutilation among others. Objective The objectives study were to find out current prevalence acquired gynetresia, pattern presentation, associated...

The authors wish to thank Nathaniel Schenker and Pei-Lu Chiu, whose detailed reviews and comments helped us to make many improvements to this report. In addition, special thanks to Dr. Schenker for permission to borrow text from his report (with Trivellore E. Raghunathan, Pei-Lu Chiu, Diane M. Makuc, Guangyu Zhang, and Alan J. Cohen) on the multiple imputation of family income and personal earn...

During the last two decades, large-scale high biomass algal blooms of the dinoflagellate Prorocentrum donghaiense Lu have occurred frequently in the East China Sea (ECS). The role of increasing nutrient concentrations in driving those blooms is well-established, but the source population that initiates them is poorly understood. We hypothesized that the front of Taiwan Warm Current (TWC) may se...
