To overcome these problems, this work presents a novel detector, which uses the hyperbolic tangent function (HTF) of a combination of first-order derivatives. Tests of this detector are conducted ...

This article investigates the predefined-time consensus for a class of second-order nonlinear multiagent systems via a sliding mode technique. Fuzzy logic systems are utilized to estimate unknown ...

Distance functions were initially defined on the input or output production possibility sets by Shephard (1953, 1970) and extended to a graph representation of the technology by Fare, Grosskopf and ...

Here, we provide evidence that several cell types in culture actually experience local hypoxia, with important implications for cell metabolism and function. We focused initially on adipocytes, as ...
