postural control has an important role in daily activities and motor independence. in recent years, conscious aspects of postural control such as attention and cognitive processes have received attention for balance optimization performance. therefore, the present study designed to examine the age–related differences in postural control in the internal and external focus of attention. for this ...
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 this study, twenty barley lines and cultivars were studied using randomized complete block design with three replications in eight cold regions of Iran, including Arak, Ardebil, Hamedan, Jolge rokh, Karaj, Mashhad, Tabriz and Miandoab for two cropping seasons during 2010-2012. Simple and combined analyses of variance were performed over the data collected from different regions. The genotype...
Objectives: The authors of this paper hypothesized that vibration stimulation applied by a vibratory orthosis improves balance in patients with Parkinson’s disease (PD). In this study we evaluate this hypothesis. Methods & Materials: Fourteen PD patients (12 male and 2 female) with mean age of 59.9±9.1 (±SD) years were participated in this cross- sectional study. Using Biodex balance system,...
The objective of this experiment was to analyze genotype × environment (GE) interaction for grain yield of 20 durum wheat genotypes to identify the yield stability and adaptability of genotypes using GGE biplot method as well as some univariate stability statistics. The genotypes were evaluated in three rainfed stations of Sararood (Kermanshah), Maragheh and Shirvan, Iran under both rainfed and...
drought stress is the most important environmental constraint contributing to grain yield instability of maize(zea mays l.). evaluation of maize genotypes under different stresses would be useful for identifying genotypes that combine stability with high yield potential for stress-prone areas. this study was conducted to estimate grain yield stability of maize hybrids and to identify hybrids th...
Sorghum is an important forage crop used as silage, fresh forage and dry forage. To evaluate the yield stability of 16 genotypes; cultivars, lines and hybrids, of forage sorghum, experiments were conducted using randomized complete block design with three replications during 2016-17 at Karaj, Isfahan, Gorgan, and Mashhad field stations, Iran. The results of combined analysis of variance showed ...
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
Indigenous diploid cotton is cultivated in many areas of country due to the saline soil and water. To study adaptability and seedcotton yield stability of three promising native cotton lines selected from interspecific hybrids of G. herbaceum & G. arboreum including three lines along with two diploid controls were planted in a randomized complete block design in four locations (Kashmar, Nis...
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 ...
