Irrational Guards are Sometimes Needed

In this paper we study the art gallery problem, which is one of the fundamental problems in computational geometry. The objective is to place a minimum number of guards inside a simple polygon so that the guards together can see the whole polygon. We say that a guard at position x sees a point y if the line segment xy is contained in the polygon. Despite an extensive study of the art gallery pr...

Appendicitis is easily missed or wrongly diagnosed - imaging is needed

No value restriction is needed for algebraic effects and handlers

We present a straightforward, sound, Hindley-Milner polymorphic type system for algebraic effects and handlers in a call-by-value calculus, which, to our surprise, allows type variable generalisation of arbitrary computations, and not just values. We first recall that the soundness of unrestricted call-byvalue Hindley-Milner polymorphism is known to fail in the presence of computational effects...

Sometimes, more is better.

(See the article by El Sahly et al, on pages 703–12.) Influenza causes significant morbidity and mortality with an estimated 36 000 attributable deaths in the United States annually [1]. Human immunodefi-ciency virus (HIV) infection, specifically , advanced disease (CD4 count ,200 cells/lL), has been associated with excess morbidity and mortality [2]. With the use of combination antiretroviral ...
