Travelling far but staying close to home.
A n overwhelming majority of the global burden of morbidity and mortality caused by sexually transmitted infections (STI) and HIV is borne by the world’s poorest countries (fig 1). In a world increasingly ‘‘shrunk’’ by modern communications, what are the common issues preoccupying the international community of researchers in our field? In planning this themed issue, published on World AIDS Day...
متن کاملStaying Close to a Curve
Given a point set S and a polygonal curve P in R, we study the problem of finding a polygonal curve through S, which has a minimum Fréchet distance to P . We present an efficient algorithm to solve the decision version of this problem in O(nk) time, where n and k represent the sizes of P and S, respectively. A curve minimizing the Fréchet distance can be computed in O(nk log(nk)) time. As a by-...
متن کاملHemoglobin-based oxygen-carrying solutions: close but still so far.
MULTIPLE approaches are important when attempting to limit allogeneic blood transfusions. My interest in developing strategies to decrease bleeding and transfusion requirements started in the early 1980s, when I was evaluating perioperative anaphylaxis and noted that transfused blood was an important cause of life-threatening hypersensitivity reactions. There are multiple reasons to reduce tran...
متن کاملClose, but not close enough
The most recent European Society of Cardiology (ESC) guidelines recommend primary percutaneous coronary intervention (PCI) as the preferred treatment for ST-segment elevation myocardial infarction (STEMI) whenever it is available within 90–120 min of the first medical contact [1]. However, timing of symptom onset appears to be hard to adjudicate precisely, and 'ischaemic time' thereby usually e...
متن کاملModified Newtonian dynamics close to home.
IN HIS PERSPECTIVE “SEEING THROUGH DARK Matter” (3 August, p. 607), Stacy McGaugh describes the success of a modified Newtonian dynamics (MOND) in explaining the flat rotation curves of galaxies without invoking dark matter. In addition to noting that MOND is in accord with available data and observations, it is possible to directly test Newtonian dynamics in the laboratory, even at low acceler...
