We present the geoBoundaries Global Administrative Database (geoBoundaries): an online, open license resource of the geographic boundaries of political administrative divisions (i.e., state, county).Contrasted to other resources geoBoundaries (1) provides detailed information on the legal open license for every boundary in the repository, and (2) f
Tobacco is an important cash crop and an ideal Board Game experimental system for studies of plant-pathogen interactions.Identification of tobacco resistance (R) genes and resistance gene analogs (RGAs) is propitious to elucidate the underlying resistant mechanisms.In recent years, the public tobacco EST (expressed sequence tags) data set, which pr
The effectiveness and validity of applying variation partitioning methods in community ecology has been questioned.Here, using mathematical deduction and numerical simulation, we made an attempt to uncover the underlying mechanisms determining the effectiveness of variation partitioning techniques.The covariance among independent variables determin
For most of the technical community, rotary flow dividers are known for synchronization of two or more hydraulic actuators.However, there is also a possibility to use them for pressure multiplication, flow regeneration, or speed control.For those applications, there is a need to describe the behavior of its quantities.This article reveals a new eva
