The aim of this paper is to offer a faster and more rigorous way for calculating the Beta-Shape. The Beta-Shape is a tight-fitting concave polygonal contour, similar to the Alpha Shape, but which remains connected when data points are farther away than the desired resolution. The proposed method uses a computational geometry approach. We also propose an improvement to the original Beta Shape, a...
Objectives Extreme concern about body shape is the main feature of eating disorders. Eating disorders co-occur with several medical and mental disorders. So a valid and reliable tool will help prevent this disorder and its consequence. Therefore, the aim of the present study was to examine psychometric properties of the Body Shape Questionnaire C8 (BSQ-C8) in a sample of women with eating diso...
Background: Body image is defined as the mental picture of each person from his/her body. Serious concerns about body shape are the main feature of eating disorders, which is common in adolescents in milder form. Extreme concerns about body shape are the main feature of eating disorders that in fewer forms are common in adolescent. Since, this kind of concerns are influenced by the culture of e...
For a fixed irrational number \(\alpha\) and \(n\in \mathbb{N}\), we look at the shape of sequence \((f(1),\ldots,f(n))\) after Schensted insertion, where \(f(i) = \alpha i \mod 1\). Our primary result is that boundary approximated by piecewise linear function with most two slopes. This explicitly described in terms continued fraction expansion for \(\alpha\). results generalize those Boyd Stee...
شروع زود هنگام دیابت نوع دو را به صورت خانوادگی maturity-onset diabet of the young (mody) می گویند. جهش در شش ژن سبب انواع mody می شود. mody3 که به دلیل جهش در ژن (hepatic nuclear factor) hnf1-alpha ایجاد می شود، در بین انواع دیگر mody عمومیت بیشتری دارد. پروتئین hnf1-alpha یک فاکتور رونویسی است که در ترشح انسولین توسط سلول های بتا پانکراس نقش دارد. جهش در ژن hnf1-alpha سبب نقص در ترشح انسولی...
The size and shape of macromolecules such as proteins and nucleic acids play an important role in their functions. Prior efforts to quantify these properties have been based on various discretization or tessellation procedures involving analytical or numerical computations. In this article, we present an analytically exact method for computing the metric properties of macromolecules based on th...
