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...

Active cannulas, so named because of their potential medical applications, are a new class of continuum robots consisting of precurved, telescoping, elastic tubes. As individual component tubes are actuated at the base relative to one another, an active cannula changes shape to minimize stored elastic energy. For the first time, we derive the differential kinematics of a general n tube active c...

Let Γ be a congruence subgroup of SL(2,Z). The modular curve X(Γ) and its Jacobian variety J(Γ) are very important objects in number theory. For instance, the problem of determining all possible structures of (Q-)rational torsion subgroup of elliptic curves over Q is equivalent to that of determining whether the modular curves X1(N) have non-cuspidal rational points. Also, the celebrated theore...

Let p and q be two distinct prime ideals of Fq[T ]. We use the Eisenstein ideal of the Hecke algebra of the Drinfeld modular curveX0(pq) to compare the rational torsion subgroup of the Jacobian J0(pq) with its subgroup generated by the cuspidal divisors, and to produce explicit examples of Jacquet-Langlands isogenies. Our results are stronger than what is currently known about the analogues of ...

Suppose K is a field of characteristic zero, Ka is its algebraic closure, f(x) ∈ K[x] is an irreducible polynomial of degree n ≥ 5, whose Galois group coincides either with the full symmetric group Sn or with the alternating group An. Let q be a power prime, Pq(t) = t q −1 t−1 . Let C be the superelliptic curve y = f(x) and J(C) its jacobian. We prove that if p does not divide n then the algebr...

The aim of this paper is to study differential properties of orthogonal polynomials with respect to a discrete Laguerre–Sobolev bilinear form with mass point at zero. In particular we construct the orthogonal polynomials using certain Casorati determinants. Using this construction, we prove that they are eigenfunctions of a differential operator (which will be explicitly constructed). Moreover,...

1. Some basic facts Denote by O = ON+1 the ring of germs of holomorphic functions f = f(z0, · · · , zN ) defined in a neighborhood of ~0 ∈ CN+1. We denote by m ⊂ O the maximal ideal of O, f ∈ m ⇐⇒ f(~0) = 0. Let f ∈ m. Assume ~0 is an isolated critical point of f , i.e. ~0 is an isolated point of the variety ∂zif = 0, ∀i = 0, · · · , N. We define the Jacobian ideal of f to be the ideal Jf ⊂ O g...

Our informal description of the modularity of a definable set X of Morley dimension and degree 1 should have been: “There is no n-dimensional definable family of definable subsets of X × X with n ≥ 2, each of Morley dimension and Morley degree 1 and with pairwise intersections finite” in place of “There should be no infinite definable family of definable subsets of X×X , each of Morley dimensio...
