We examined the genetic architecture of functional brain connectivity measures in resting state electroencephalographic (EEG) recordings. Previous studies in Dutch twins have suggested that genetic factors are a main source of variance in functional brain connectivity derived from EEG recordings. In addition, qualitative descriptors of the brain network derived from graph analysis - network clu...

Introduction: The lack of expressing an opinion in employees working in organizations can cause a phenomenon called organizational silence. Organizational silence has a damaging effect on employee’s productivity. The importance of organizational sound and silence in organizational performance is currently one of the fundamental organizational challenges. Method: In this was descriptive study, ...

this study was conducted to investigate the genotype¬×¬environment interaction effects on yield and yield components of wheat. ten cultivars of wheat were evaluated in 8 environments (combinations of two levels of nitrogen and four irrigation regimes) in growing season of 2006-2007 at the research farm of isfahan university of technology. based on the stability parameters of eberhart and russel...

one of the most important factors in the development of societies, consider to traning. identification and training needs analysis, is a prerequisite for a successful educational system and determine the training needs is considered the first step of educational planning. the purpose of this study was to investigate educational needs of engineers, rice supervisors engineering agricultural engin...

In this chapter the authors first present the basic algorithm of PLS Path Modeling by discussing some recently proposed estimation options. Namely, they introduce the development of new estimation modes and schemes for multidimensional (formative) constructs, i.e. the use of PLS Regression for formative indicators, and the use of path analysis on latent variable scores to estimate path coeffici...

Correlation coefficient and path analysis studies was conducted with eight parents and their 28 F1 crosses for twelve component characters including seed yield and revealed significant positive association of pods per plant, harvest index and clusters per plant with seed yield in parental generation whereas in F1 generation, significant positive association of clusters per plant, pods per plant...

In this paper, we examine the movement of particles within a continuous powder mixer using PEPT (Positron Emission Particle Tracking). The benefit of the approach is that the particle movement along the vessel can be measured non-invasively. The effect of impeller rotation rate, powder flow rate, and powder cohesion on the particle trajectory, dispersive axial transport coefficient, and residen...

Normal brain functioning is presumed to depend upon interacting regions within large-scale neuronal networks. Increasing evidence exists that interictal network alterations in focal epilepsy are associated with cognitive and behavioral deficits. Nevertheless, the reported network alterations are inconclusive and prone to low statistical power due to small sample sizes as well as modest effect s...

We proposed a deterministic multidimensional growth model for small-world networks. The model can characterize the distinguishing properties of many real-life networks with geometric space structure. Our results show the model possesses small-world effect: larger clustering coefficient and smaller characteristic path length. We also obtain some accurate results for its properties including degr...

Crepuscular and solar rays are visible by means of the contrast between sunlit and (usually) cloud-shaded portions of the atmosphere. Their visibility depends on (1) the volume angular-scattering coefficient (), (2) the brightness of the sunlit sky, and (3) the integrated optical path through the shadowed regions of the atmosphere. We show that the geometry of path length through the umbra (3) ...
