In a recent study, we showed that the springtail Folsomia candida was quite sensitive the neonicotinoid insecticides imidacloprid and thiacloprid. This study aimed at determining the toxicity of both compounds to F. candida following exposure over three generations, in natural LUFA 2.2 standard soil. In the first generation, imidacloprid was more toxic than thiacloprid, with LC50s of 0.44 and 9...

This research focuses on the diffusion patterns of the adjacent generations of technology and its relation to the time that elapses between them (intergeneration time). The authors analyze 45 new technologies in 15 industries and find that the adoption curves systematically vary across generations from 2 years for dynamic random-access memory (DRAM) chips to more than 30 years for steelmaking. ...

A recent JAMS article reported the following finding: the longer the time between the launch of two adjacent generations in the same product category, the lower the initial rate of adoption of the later generation but the higher its subsequent rate of growth. This note shows that these results could be a method artifact, since they vanish once one controls for differences in the length of the d...

The state-estimation and optimal control of multigeneration systems are challenging for wide-area having numerous distributed automatic voltage regulators (AVR). This paper proposes a modified Q-learning method algorithm that aim to improve the convergence approach enhance dynamic response stability terminal multiple generators in experimental Western System Coordinating Council (WSCC) large-sc...

In order to assess the potential of electromagnetic fields (EMF) to influence the process of carcinogenesis, it will be necessary to supplement epidemiological studies with controlled laboratory studies in animals. There are now a number of suitable assays available that focus on different histopathological forms of cancer and on different stages of carcinogenesis--induction, promotion, progres...
