Baculovirus recombinant-expressed antigens of Norwalk viruses (rNV) and a Mexico strain (rMX) of the Snow Mountain serogroup of human caliciviruses (HuCVs) were used in enzyme immunoassays to study the antibody prevalence among the Kuwaiti population and foreign workers employed in Kuwait. The antibody titers in 16 different age groups which ranged from(More)
We investigate computable subshifts and the connection with effective symbolic dynamics. It is shown that a decidable Π 0 1 class P is a subshift if and only if there is a computable function F mapping 2 N to 2 N such that P is the set of itineraries of elements of 2 N. Π 0 1 subshifts are constructed in 2 N and in 2 Z which have no computable elements. We(More)
We investigate the computability of countable subshifts in one dimension, and their members. Subshifts of Cantor–Bendixson rank two contain only eventually periodic elements. Any rank two subshift in 2ℤ is decidable. Subshifts of rank three may contain members of arbitrary Turing degree. In contrast, effectively closed ( $\Pi^{0}_{1}$ ) subshifts of rank(More)
The computability of countable subshifts and their members is examined. Results include the following. Subshifts of Cantor-Bendixson rank one contain only eventually periodic elements. Any rank one subshift, in which every limit point is periodic, is decidable. Sub-shifts of rank two may contain members of arbitrary Turing degree. In contrast, effectively(More)
BACKGROUND Laparoscopic sleeve gastrectomy (SG) is becoming a popular and preferred primary bariatric intervention; however, its applicability in the adolescent age group remains controversial. The aim of this study is to evaluate the efficacy of SG in treating obesity and its co-morbidities among adolescents. METHODS A retrospective study was conducted(More)
