Regression is used commonly to test hypotheses involving causal relationships, with the choice of model being based on its significance and goodness of fit. Classification Learning Classification supervised learning is a form of pattern recognition designed to predict a single, nonnumerical output, or ...
A ball valve is a form of quarter-turn valve which uses a hollow, perforated and pivoting ball to control flow through it. It is open when the ball's hole is in line with the flow and closed when it is pivoted90-degrees by the valve handle. The handle lies flat in alignment with ...

In biodesulfurization (BD) at haloalkaline and dO2-limited conditions, sulfide-oxidizing bacteria (SOB) effectively convert sulfide into elemental sulfur t
In an ecosystem, different species/populations interact with each other to form complicated networks through various types of interactions such as predation, competition and mutualism. On the basis of ecological interactions, ecological networks can be grouped as antagonistic, competitive and mutualistic ne...
each antenna calculates partials of the parameters to be estimated and corresponding O-C measurements synchronously in parallel. These values are organized in two groups and will be automatically pushed to the “Engine” library to form normal equations. The parameters and O-C measurements are manage...
3c). Taking the negatively charged wall of the microchannel as an example, when the liquid contacts the negatively charged wall of the microchannel, the cations in the liquid gather on the wall of the microchannel to form a thin electric double layer (EDL) (0.1 nm-10 nm). Under the ...
Rarely a chronic form of Q fever develops months after the acute illness, most commonly in the form of endocarditis[1]. Children develop clinical disease less frequently[7, 8]. Because of its non-specific presentation Q fever can only be suspected on clinical grounds and requires serologic ...
Oomycetes are a large group of economically and ecologically important species. Its most notorious member is Phytophthora infestans, the cause of the devastating potato late blight disease. The life cycle of P. infestans involves hyphae which differentia
