We study asset prices in an economy where some investors categorize risky assets into different styles and move funds among these styles depending on their relative performance. In our economy, assets in the same style comove too much, assets in different styles comove too little, and reclassifying an asset into a new style raises its correlation with that style. We also predict that style retu...

Assumptions about the dynamic and distributional behavior of risk factors are crucial for the construction of optimal portfolios and for risk assessment. Although asset returns are generally characterized by conditionally varying volatilities and fat tails, the normal distribution with constant variance continues to be the standard framework in portfolio management. Here we propose a practical ...

Sweet potato breeding in Africa, more especially Nigeria, has mainly focused on improving productivity farmers' fields and fresh root consumption. In order to target the program, study was conducted estimate magnitude of genotype × environment interaction (G E) select stable high yielding sweet genotypes for yield Cylas severity two locations, identify most discriminating representative test en...

tively, are 82% and 66% identical to their mouse and rat counterparts. are worm specific G␣'s that do not correspond to any particular mammalian ␣ subunit (Lochrie et al., 1991). In addition, one G␤ subunit has been identified in C. ele-gans (van der Voorn et al., 1990). Dallas, Texas 75235 We have examined the function of Gq␣ in C. elegans. The mammalian Gq␣ family is comprised of four members...

Background and Objective: Preeclampsia (PE) is a pregnancy complication with the signs of kidney damage. The effect of S-Allyl-cysteine (SAC) on inflammatory cytokines was evaluated to prevent PE-induced renal complications. Materials and Methods: Wistar rats were divided into seven groups: 1) control, 2) PE, 3) EC, 4) PE+SAC50, 5) PE+SAC200, 6) EC+SAC50, and 7) EC+SAC200. In Groups 1-3, the r...

Increasing yield and adaptability of brown black rice in functional sub-optimal environments begins with increasing genetic diversity through conventional crosses between diverse germplasm. This study aims to determine the yield, diversity, heritability, interactions genotypes two different growing environments. The was conducted April-August 2021. designed using a two-factor Randomized Block D...
