The NE2001 model for the free electron distribution of the Milky Way includes ad hoc electron “clumps” to reconcile line of sight observables with basic model predictions (Cordes et al. 2002). While MAGPIS (Multi-Array Galactic Plane Imaging Survey) is insensitive to emission from individual diffuse HII regions (ne ∼10 cm), by investigating the 20 cm maps we are able to verify their assumption ...

Information technology today is a complex area, in which new problems and challenges constantly arise and innovations emerge. The ability to incorporate an innovation in time or to solve a problem efficiently can mean competitive advantages for some firms. Being responsive in IT involves being alert, knowledgeable and prepared to face technical problems and to solve them in appropriate ways. In...

We define the notion of a weakly pointed tree, and characterize the amount of genericity necessary to prevent a uniformly branching tree being weakly pointed. We use these ideas to show there is no topological analogue of a measure-theoretic selection theorem of Graf and Mauldin. We consider some topological and recursion-theoretic questions motivated by the following measure-theoretic result o...

This study examines the impact of nation’s legal system on corporate disclosures. However, this study breaks with prior research in two significant ways. First, this study extends prior research by analyzing differences in disclosure practices in Roman-Germanic Law nations of different origins within this legal family. Second, this study focuses on a single disclosure issue rather than general ...

Background This study aimed to compare the clinical and radiographic outcomes of using two different oversized rasps in total hip arthroplasty (THA) with a composite beam cemented stem (DCM-J). Methods A consecutive series 105 hips underwent hybrid THA DCM-J between 2006 2010. Among patients minimum 10-year follow-up, 1.5-mm rasp was used 38 (group S), whereas 0.5-mm 36 M). The Japanese Orthope...
