Using a continuum bead-spring Monte Carlo model, we study the anomalous diffusion dynamics of a self-avoiding tethered membrane by means of extensive computer simulations. We focus on the subdiffusive stochastic motion of the membrane's central node in the regime of flat membranes at temperatures above the membrane folding transition. While at times, larger than the characteristic membrane rela...

the polarimetric entropy and the alpha angle are two important parameters for analyzing polarimetric synthetic aperture radar data. they demonstrate the degree of randomness in the polarization of the received signal and scattering mechanism of scatterers respectively. recently, there has been an increasing interest in compact polarimetry due to its advantages in comparison with full polarimetr...

Background: Long-term financial support is essential for the survival of a charitable organization. Health charities need to identify the effective factors influencing donor retention. Methods: In the present study, the items of a questionnaire were derived from both literature review and semi-structured interviews related to donor retention. Using a purposive sampling, 300 academic and exec...

Cronbach’s coefficient alpha is a widely used reliability measure in social, behavioral, and education sciences. It is reported in nearly every study that involves measuring a construct through multiple items. With non-tau-equivalent items, McDonald’s omega has been used as a popular alternative to alpha in the literature. Traditional estimation methods for alpha and omega often implicitly assu...

objectives : bayley scales of infant & toddler development is a well-known diagnostic developmental assessment tool for children aged 1–42 months. our aim was investigating validity & reliability of this scale in persian speaking children. materials & methods: the method was descriptive-analytic. translation- back translation and cultural adaptation was done. content & face validity of tranlate...

the aim of this study was to determine the validity and reliability of the basic psychological needs in exercise scale (bpnes). the method was descriptive-survey. the statistical population consisted of male and female athletes aged over 16 years who attended structured exercise programs. the sample consisted of 256 male and female athletes (m=23.03, sd=4.04) who were selected through cluster r...

awareness and preparedness for prevention of crisis plays an important role in minimizing its impacts and fatalities. this study suggests how to enhance the efficiency of crisis management through applying a resilience engineering (re) approach. the aim of this study was to design a questionnaire to assess crisis management based on re approach. in this descriptive survey, four principles of re...

the aim of the present study was to determine psychometric properties of the persian version of the group conflict questionnaire in male and female athletes. for this purpose, 281 athletes at different skill levels in 25 team and individual sports were selected through cluster random sampling method and were asked to complete the persian version of this questionnaire. firstly, the accuracy of t...

This article is a survey of methods for measuring agreement among corpus annotators. It exposes the mathematics and underlying assumptions of agreement coefficients, covering Krippendorff’s alpha as well as Scott’s pi and Cohen’s kappa; discusses the use of coefficients in several annotation tasks; and argues that weighted, alpha-like coefficients, traditionally less used than kappalike measure...

Sedimentation-coefficient measurements on human IgG, fibrinogen and alpha(2)-macroglobulin and pig thyroglobulin were made at rotor velocities of 15220-59780 rev./min and 25.0 degrees C in capillary-type synthetic-boundary cells or ordinary cells. At the lowest velocity, IgG and fibrinogen gave results several per cent higher than at other velocities, whereas alpha(2)-macroglobulin and thyroglo...
