Abstract We investigate a novel way to encourage separation between firms, causing local pollution, and their victims (households): payments from households distant polluting firms. These do not require monitoring of firms’ emissions or abatement costs. In our model, firms can choose two locations (A B, with A larger than B). Households incur environmental damage in the same location. Under lai...

Background: Patients with high myopia have higher risk of eye diseases. Currently, Implantable collamer lens (ICL) implantation is one of the widely used refractive intraocular lens surgical intervention methods. Purpose: To evaluate the effectiveness of implantable collamer lens (ICL) implantation in high myopia patients and the changes in wavefront aberrations after the operation. Methods: Th...

Visible nanocrystal-based light-emitting diodes (LEDs) are about to become commercially available. However, their infrared counterparts suffer from two key limitations. First, III–V semiconductor technologies strong competitors. Second, potential for operation beyond 1.7 µm remains unexplored. The range 1.5 4 corresponds a technological gap in which the efficiency of interband quantum-well-base...

We are interested in finding bounds for the distant-2 chromatic number of geometric graphs drawn from different models. We consider two undirected models of random graphs: random geometric graphs and random proximity graphs for which sharp connectivity thresholds have been shown. We are interested in a.a.s. connected graphs close just above the connectivity threshold. For such subfamilies of ra...
