Shallow seismic methods have matured noticeably over the two decades since the first SAGEEP was held in 1988. At that time, the world’s scientific literature contained no more than a dozen refereed papers on shallow (less then 30 meters deep) reflection, but now there are hundreds of such examples. Analysis of surface waves was done with two-channel seismic systems in the 1980’s, whereas seismo...

Among the large number of microfluidic components realized up to now, micropumps clearly represent the case of a “long runner” in science. A brief literature review reveals, that one of the first scientific papers on a micropump dates from 1978 [4], which is more than two decades ago. An increasing number of publications is found from that time on representing widespread research activities, an...

Twenty years have now elapsed since Ashbaugh and Petty first described the syndrome of acute respiratory failure associated with a wide spectrum of clinical conditions. During the past two decades, significant advances have emerged in our understanding of the clinical conditions associated with the syndrome and the pathophysiological changes affecting the alveolar-capillary membrane responsible...

The striatum and its ventral extension the nucleus accumbens (NAcc) are the main inputs structure of the basal ganglia circuit (Figure 1). While the striatum appears to be essential for the selection and initiation of actions and for the learning of habits and skills, the NAcc seems to be more involved in motivation and reward. Interestingly, dysfunctional plasticity of these structures has bee...
