The yellow variegated2 (var2) mutant in Arabidopsis thaliana has been studied as a typical leaf-variegated mutant whose defect results from the lack of FtsH2 metalloprotease in chloroplasts. The var2 green sectors suffer from photo-oxidative stress and accumulate high levels of reactive oxygen species (ROS) because of compromised Photosystem II repair. This study investigated and compared micro...

In the national airspace system, sectors get overloaded due to high traffic demand and inefficient airspace designs. Overloads can be eliminated in some cases by redesigning sector boundaries. This paper extends the Voronoi-based sector design method by automatically selecting the number of sectors, allowing three-dimensional partitions, and enforcing traffic pattern conformance. The method was...

PURPOSE We previously developed a method to measure visual function progression using "Progression sectors," which were derived from a clustering analysis of pointwise rates of glaucomatous visual field (VF) progression; however, only short series of VFs, where pointwise linear regression (PLR) is typically not reliable, were analyzed. The purpose of the current study is to further investigate ...

We examine an economy with n production sectors that interact via a production externality We nd a solution to the resulting dynamic di erential game between sectors and compare it to the cooperative solution As the number of sectors increases the limiting policy is the optimal policy without a production externality This policy is ine cient and depending on the sign of the externality between ...

The present paper investigates the impacts of information communication technology (ICT) on economic geography by focusing on the Japanese service sectors. The authors empirically assess the effects of ICT on the urban and rural service sectors using Japanese economic data. There are two main findings. The first indicates that the service sectors in urban areas agglomerated from 2000 to 2006. T...
