An Efficient Transformation of (-)-Quinic Acid into Carba-L-Rhamnose
No full textA novel stereoselective synthesis of carba-L-rhamnose from (-)-quinic acid is described. The title compound is obtained with an appropriate pattern of protecting groups to be used for the preparation of Streptococcus pneumoniae type 19F capsular polysaccharide repeating unit

No full textRepulsive Serial Effects in Visual Numerosity Judgments
No full textWe investigated how the approximate perceived numerosity of ensembles of visual elements is modulated by the numerosity of previously viewed ensembles depending on whether the first ensemble is held in visual working memory or not. We show that the numerosity of the previously seen ensemble has a repulsive effect, that is, a stimulus with high numerosity induces an underestimation of the following one and vice versa. This repulsive effect is present regardless of whether the first stimulus is memorized or not. While subtle changes of the experimental paradigm can have major consequences for the nature of interstimulus dependencies in perception, generally speaking the fact that we found such effects in a visual numerosity estimation task confirms that the process by which human observers produce estimates of the number of elements bears analogies to the processes that lead to the perception of visual dimensions such as orientation
