Sequence transformations are important tools for the convergence acceleration of slowly convergent scalar sequences or series and for the summation of divergent series. The basic idea is to construct from a given sequence { sn} a new sequence { s ′ n} = T ({ sn} ) where each s ′ n depends on a finite number of elements sn1 , . . . , snm . Often, the sn are the partial sums of an infinite series...

Introduction As a method of evaluation, cost-effectiveness analysis is relatively simple in its principles, with a thorough presentation given by Levin and McEwan (2001). However, these simple principles belie the complexity of cost-effectiveness analysis in practice. Perhaps these complexities explain the dearth of proper cost-effectiveness studies, a dearth identified by Levin (2001), and – i...

Jarcho-Levin syndrome is a rare genetic disorder characterized by respiratory insufficiency and multiple spine and rib abnormalities. It was first described by Jarcho and Levin in 1938. Spondylocostal dysostosis (SCD) and spondylothoracic dysostosis (STD) are the subtypes of Jarcho-Levin Syndrome, which show a hereditary picture. Autosomal dominant, autosomal recessive, and sporadic cases have ...
