objective: social determinant of health (sdh) are different from medical care and services. these factors themselves are affected by social policies, and they influence health more than medical care and services do. due to the importance of chronic non-communicable diseases especially diabetes in yazd, and assuming the effect of sdh, the present study was conducted in order to examine the relat...

background and purpose: the age of the onset of obsessive-compulsive disorder (ocd) and its manifestation is now identified at childhood. in the present study, we aimed to epidemiologically assess ocd and its main determinants in school-age children. materials and methods: this cross-sectional study was performed on 600 consecutive schoolage children (7-12 years old) in primary schools at kerma...

We study analytically a thermal Brownian motor model and calculate exactly the Onsager coefficients. We show how the reciprocity relation holds and that the determinant of the Onsager matrix vanishes. Such a condition implies that the device is built with tight coupling. This explains why Carnot's efficiency can be achieved in the limit of infinitely slow velocities. We also prove that the effi...

In this paper, we discuss two distinct multivariate time series models that extend the univariate ARFIMA model. We describe algorithms for computing the covariances of each model, for computing the quadratic form and approximating the determinant for maximum likelihood estimation, and for simulating from each model. We compare the speed and accuracy of each algorithm to existing methods and mea...

Superregular matrices are a class of lower triangular Toeplitz matrices that arise in the context of constructing convolutional codes having a maximum distance profile. These matrices are characterized by the property that no submatrix has a zero determinant unless it is trivially zero due to the lower triangular structure. In this paper, we discuss how superregular matrices may be used to cons...

Distribution patterns of specific fucose-containing antigens having X determinant (Gal beta 1----4[Fuc alpha 1----3]GlcNAc) as well as the di- or trimeric X determinants (Gal beta 1----4[Fuc alpha 1----3]GlcNAc beta 1----3Gal beta 1----4[Fuc alpha 1----3]-GlcNAc) in the developing human embryo and fetus and in human cancer have been examined using immunohistological techniques. Tissue sections ...

This paper proposes a novel remote sensing image segmentation method based on Gaussian mixture model and SURF algorithm. Firstly, is used for segmentation. Then the surf matching algorithm adopted eliminating misidentified areas. The determinant of Hession matrix (DoH) to detect key points in image. non-maximum suppression interpolation operation are utilized search locate extreme points. maxim...
