A room is a simple polygon with a prespecified point, called the door, on its boundary. Search may be conducted by two guards on the boundary who keep mutual visibility at all times, or by a single boundary searcher with a flashlight. Search starts at the door, and must detect any intruder that was in the room at the time the search started, preventing the intruder from escaping through the doo...

The limitations of mathematical logic either as a tool for the foundations of mathematics, or as a branch of mathematics, or as a tool for artificial intelligence, raise the need for a rethinking of logic. In particular, they raise the need for a reconsideration of the many doors the Founding Fathers of mathematical logic have closed historically. This paper examines three such doors, the view ...

The articles in this supplement to Pediatrics raise serious questions about the current policies and practices that affect children and youth with special health care needs (CYSHCN) from traditionally underserved communities and are a call to action at a time when the United States is experiencing both unprecedented demographic shifts and a serious economic downturn. Although CYSHCN from unders...

To improve the existing mechanism for opening the car-door of a mobile shop vehicle, we first apply the contradiction matrix and the idealized design technique of the Theory of the Solution of Inventive Problems (TRIZ) as a reference to ameliorate an automatic car-door opening (closing) system, and find a scheme matching requirements in design. Next, a motor gear transmission system is designed...

Using data from a randomized controlled trial involving door-to-door HIV education, homebased voluntary HIV counseling and testing (VCT), and facility-based VCT, the latter of which relies on conditional cash transfers, we find that both home-based VCT and facility-based VCT significantly increase HIV testing take-up, with the former being more effective in detecting HIV-positive cases. We also...
