In this paper, we study the existence theorem for [Formula: see text] [Formula: see text] solutions to a class of 1-dimensional infinite time interval backward stochastic differential equations (BSDEs) under the conditions that the coefficients are continuous and have linear growths. We also obtain the existence of a minimal solution. Furthermore, we study the existence and uniqueness theorem f...

BACKGROUND AND OBJECTIVE Reference limits are widely used in anthropometry, the behavioral sciences, medicine, and clinical chemistry. They describe the distribution of a quantitative variable in a healthy population, and are often a smooth function of age or another determinant. Thus, instead of estimating reference limits separately for several age groups, it is more economical and parsimonio...

the purpose followed in this descriptive- correlational research was to investigate the factors influencing an application of information technology (it) in dairy farms’ management in the west parts of tehran province .the statistical population of the study consisted of 284 dairy farmers, from among whom 82 were selected as sample using cochran formula along with proportionate stratified sampl...

OBJECTIVE Serum low density lipoprotein (LDL) level is an important biomarker for coronary artery disease (CAD). As direct LDL measurement is expensive and not cost effective, especially in a large population, it is estimated by Friedewald formula. Therefore, we decided to compare the direct LDL measurement method with LDL measured by Friedewald formula in a large general population for the fir...

We present a periodic nonlinear scalar delay differential equation model for population with short reproduction period. By transforming the to discrete dynamical system, we reduce infinite dimensional problem one dimension. determine basic number not merely as spectral radius of an operator, but explicit formula and show that is serves threshold parameter stability trivial equilibrium permanence.

Ewens' sampling distribution is investigated for a structured population. Samples are assumed to be taken from a single subpopulation that exchanges migrants with other subpopulations. A complete description of the probability distribution for such samples is not a practical possibility but an equilibrium approximation can be found. This approximation extracts the information necessary for cons...
