background and aim: motor vehicle accidents are common cause of mortality, morbidity and disability. human factors are principle cause for frequency of motor vehicle accident. in most studies, 52-40% lower limb injuries are trauma from a motorcycle accident. these accidents cause high financial cost and harm for society. materials and methods: in this study, patients with lower limb injuries re...

We first prove that if y * optimizes (16), then |y * j | ≤ M, 1 ≤ j ≤ n. (EC.1) Suppose that in (16), given y and D, z * (y; D) optimizes ϕ(y; D). Then the objective function is C(y) = h · E[y − Az * (y; D)] + b · E[D − z * (y; D)]. i:a ji >0 a ji b i a ji E[D i − z * i ] ≥ ζ j A j · E[D − z * ] ≥ ζ j (A j · E[D] − y j), and C(y) ≥ h · E[y − Az * ] ≥ h j (y j − A j · E[z * ]) ≥ h j (y j − A j ·...

In this paper, an iterative method is proposed for solving matrix equation $sum_{j=1}^s A_jX_jB_j = E$. This method is based on the global least squares (GL-LSQR) method for solving the linear system of equations with the multiple right hand sides. For applying the GL-LSQR algorithm to solve the above matrix equation, a new linear operator, its adjoint and a new inner product are dened. It is p...

background: cervical cancer is one of the most common types of women’s reproductive cancers. a major risk factor for cervical cancer is exposure to a group of common sexually transmitted viruses called human papillomavirus  (hpv). the over expression of hpv 16 i.e., e6 antigen in the tumors of suspected cervical cancer tissues. however e-6 antigen has hyaluronan binding protein site. methods: t...

Let $G=(V,E)$, $V={v_1,v_2,ldots,v_n}$, be a simple graph with$n$ vertices, $m$ edges and a sequence of vertex degrees$Delta=d_1ge d_2ge cdots ge d_n=delta$, $d_i=d(v_i)$. Ifvertices $v_i$ and $v_j$ are adjacent in $G$, it is denoted as $isim j$, otherwise, we write $insim j$. The first Zagreb index isvertex-degree-based graph invariant defined as$M_1(G)=sum_{i=1}^nd_i^2$, whereas the first Zag...
