NICE (National Institute for Health and Clinical Excellence) guidelines for new entrant tuberculosis (TB) screening recommend chest x ray (CXR) for immigrants from countries with TB incidence >40/10(5), and tuberculin skin test (TST) for people with normal CXR from very high TB prevalence countries. A revised screening policy using first-line QuantiFERON-TB Gold (QFT) in high risk immigrants wa...

Rounded Arithmetic is the traditional way of presenting previous year accounts. The method of showing rounded sums of vectors in which the arithmetic still “adds up” and the errors in the display of the components are bounded by twice the maximum rounding error have been well known for at least 30 years in spite of there being little or nothing in the literature and no attempt to implement this...

It?s hard to definitively determine what caused your heart to pound, but there are multiple possibilities. It might be that you experienced it as a common side effect of marijuana use. It?s also possible that your experience was due to feeling anxious, which could have been induced or exacerbated by marijuana use. Another reason for this is that your marijuana was laced with another substance w...

OBJECTIVES To estimate the cost effectiveness of statin treatment in preventing coronary heart disease (CHD) and to examine the effect of the CHD risk level targeted and the cost of statins on the cost effectiveness of treatment. DESIGN Cohort life table method using data from outcome trials. MAIN OUTCOME MEASURES The cost per life year gained for lifelong statin treatment at annual CHD eve...

We often need to refer to adjacent elements (e.g., vertices, edges and faces) in triangle meshes for rendering, mesh simplification and other processes. It is, however, sometimes impossible to prepare the enormous memory needed to represent element connectivity in gigantic triangle meshes. We proposed a memory efficient scheme for referring to adjacent faces around a vertex in non-manifold tria...
