BACKGROUND: WHO and UNICEF have recently developed the "Integrated Management of Childhood Illness" (IMCI) as an efficient strategy to assist developing countries reduce childhood mortality. Early experience with IMCI implementation suggests that clinical training is essential but not sufficient for the success of the strategy. Attention needs to be given to strengthening health systems, such a...

Various computational models have been developed to transfer annotations of gene essentiality between organisms. However, despite the increasing number of microorganisms with well-characterized sets of essential genes, selection of appropriate training sets for predicting the essential genes of poorly-studied or newly sequenced organisms remains challenging. In this study, a machine learning ap...

Thus, consider a set of matched points ui ↔ ui for i = 1, . . . , 6 and suppose that the points x1, . . . ,x4 corresponding to the first four matched points lie in a plane in space. Let this plane be denoted by π. Suppose also that no three of the points x1, . . . ,x4 are collinear. Suppose further that the points x5 and x6 do not lie in that plane. Various other assumptions will be necessary i...

BACKGROUND Essential tremor (ET) is often familial and phenotypic features may be shared within families. Cranial (neck, voice, and jaw) tremor is an important feature of ET. We examined whether cranial tremor aggregates in ET families, after controlling for other factors (age, tremor severity, and duration). METHODS Among ET probands and relatives enrolled in a genetic study at Columbia Univ...

Accessibility and availability of drugs has been a matter of great concern for health services all over the world, especially for less developed countries. The World Health Organization has devoted considerable time to this matter, as evidenced in several documents and policies, such as model lists of essential drugs and the strategy "Health for All by the Year 2000". The WHO policy for essenti...

We suggest altering the fundamental strategy in Fundamental or Essential Matrix estimation. The traditional approach first estimates correspondences, and then estimates the camera geometry on the basis of those correspondences. Though the second half of this approach is very well developed, such algorithms often fail in practice at the correspondence step. Here, we suggest altering the strategy...
