Multi-class classifier training using traditional meta-algorithms such as the popular One-vs-One (OvO) method may not always work well under cost-sensitive setups. Also, during inference, OvO becomes computationally challenging for higher class counts K O(K^2) is its time complexity. In this paper, we present Opt-OvO, an optimized (resource-friendly) version of algorithm to enable high-performa...

The reproductive success of wild birds has been affected by exposure to multiple contaminants. Reproduction of captive American kestrels (Falco sparverius) was suppressed when adult birds were exposed to dietary polychlorinated biphenyls (PCBs). In this study, the reproductive effects of in ovo exposure to PCBs is explored, along with determining effects on reproduction in second-generation bir...

This experiment was conducted to evaluate the effect of in ovo injection (IOI) of calcium carbonate nano-particles (CCN) on post-hatch bone and blood parameters and performance of broiler chickens. Fertile eggs (n=400) were distributed into 4 groups of 100 eggs. On the first day of incubation, 2 groups were injected with 0.5 mL of either 100 or 200 ppm CCN/egg dissolved in normal saline and two...

The capacity to image a growing embryo while simultaneously studying the developmental function of specific molecules provides invaluable information on embryogenesis. However, until recently, this approach was accomplished with difficulty both because of the advanced technology needed and because an easy method of minimizing damage to the embryo was unavailable. Here, we present a novel way of...

Betaine alleviates high-fat diet-induced fatty liver and prenatal betaine programs offspring hepatic lipid metabolism. Excessive corticosterone (CORT) exposure causes fatty liver in chickens, yet it remains unknown whether and how prenatal betaine modulates the susceptibility of CORT-induced fatty liver later in life. In this study, fertilized eggs were injected with saline or betaine before in...
