Congruence between changes in phenotypic variance and developmental noise in inter-population hybrids was analysed to test whether environmental canalization and developmental stability were controlled by common genetic mechanisms. Developmental stability assessed by the level of fluctuating asymmetry (FA), and canalization by the within- and among-individual variance, were measured on several ...

in order to determinate appropriate stability parameters, six statistics were studied for flower yield stability of 35 rosa damascena landraces in 8 locations over two years (2007-8) in iran, using a randomized complete blocks design with 3 replications. a positive correlation between environmental variance (s2) and flower yield suggested that only low yield landraces develop a similar phenotyp...

stability analysis and g*e interaction of eight commercial monogerm cultivars of sugar beet were evaluated in three years at 11 major sugar beet producing locations karaj, mashhad, miandoab, esfahan, shiraz, kermanshah, kerman, moghan, hamedan, khoy, and brojerd. a randomized complete block design with four replications was used.in each location cultivars  rasoul, shirin, univers, orbis, 7112hy...

The Minimum Variance portfolio is subject to varying degrees of stability and robustness. We, therefore, propose a theoretical measure its relative Marchenko–Pastur derived random correlation matrix. We demonstrate practical use on the S&P 400, 500, 600 Russell 1000. Using historic market data from 2002 2021, we perform an optimisation empirical matrix eigenvalue distribution determine implied ...

An Ann-category is a categorification of rings. Regular Ann-categories were classified by Shukla cohomology of algebras. In this paper, we state and prove the precise theorem on classification of Ann-categories in the general case based on Mac Lane cohomology of rings. AMS subject classifications: 18D10, 16E40

The essential oil yield stability of damask rose (Rosa damascena Mill.) as an important medicinal and aromatic plant in different environments has not been well documented. In order to determine appropriate stability parameters, six statistics were studied for essential oil stability of 35 Rosa damascena landraces in seven locations (Sanandaj, Arak, Kashan, Dezful, Stahban, Ke...
