Recently, waves propagating with negative phase velocity [simply called antiwaves (AWs)] have attracted great attention in the area of nonlinear oscillatory systems. In the present work we investigate the parameter conditions for AWs. So far AWs have been revealed from systems slightly beyond Hopf bifurcation or some other instabilities, and from some wave sources with certain restricted freque...

Daily and seasonal fluctuations in mortality have been positively and significantly associated with ambient concentrations of atmospheric pollution and meteorological variables such as temperature and barometric pressure. However, much less is known about the health risk from atmospheric pollutants in the context of frequently occurring weather patterns. The objective of this study is to assess...

Inferring information related to users enables to highly improve the quality of many mobile services. For example, knowing the demographic characteristics of a user allows a service to display more accurate information. According to the literature, various works present models to detect them but, to the best of our knowledge, no one is based on the use of the spatio-temporal entropy and introdu...
