Hanwoo Carcass Genetic Parameters Genetic Progress National Breeding Scheme
2016/11/10
Carcass and price traits of 72,969 Hanwoo cows, bulls and steers aged 16 to 80 months at slaughter collected from 2002 to 2013 at 75 beef packing plants in Korea were analyzed to determine heritabilit...
Comparison of Mathematical Models Applied to F1 Dairy Sheep Lactations in Organic Farm and Environmental Factors Affecting Lactation Curve Parameter
Sheep Milk Lactation Curve Organic Farming Mathematical Models
2016/5/12
The objective of this study was to compare the goodness of fit of four lactation curve models: Wood’s Gamma model (WD), Wilmink (WL), and Pollott’s multiplicative two (POL2) and three parameters (POL3...
Genetic Parameter Estimation in Seedstock Swine Population for Growth Performances
Swine Duroc Landrace Yorkshire Heritability Growth Ultrasound
2016/5/11

Low-parameter phylogenetic estimation under the general Markov model
Markov invariants phylogenetic invariants base-composition rate-variation quartets supertrees
2012/5/2
In their 2008 and 2009 papers, Sumner and colleagues introduced the "squangles" - a small set of Markov invariants for phylogenetic quartets. The squangles are consistent with the general Markov model...
Steady-state parameter sensitivity in stochastic modeling via trajectory reweighting
Steady-state parameter sensitivity stochastic modeling trajectory reweighting
2012/2/28
Parameter sensitivity analysis is a powerful tool in the building and analysis of biochemical network models. For stochastic simulations, parameter sensitivity analysis can be computationally expensiv...
