Seven new mono- and bis-furanones, pezizolides A-G (1-7), have been isolated from the crude extract of the endolichenic fungus Peziza sp. inhabiting the lichen Xanthoparmelia sp. The structures of the new compounds were elucidated mainly by NMR and MS methods. The absolute configuration of 1-4 was assigned by the application of CD exciton chirality method, and 1 was further supported by electro...

Aim We evaluate the scale dependence of species richness–environment relationships with a continent-wide analysis of lichen epiphyte communities. Specifically, our goals are to assess: (1) the dependence of local richness on regional processes, (2) whether species richness is primarily influenced by heterogeneity in environmental conditions or the central tendency of those conditions, and (3) w...

The perception of objects in our visual world is influenced by not only their low-level visual features such as shape and color, but also their high-level features such as meaning and semantic relations among them. While it has been shown that low-level features in real-world scenes guide eye movements during scene inspection and search, the influence of semantic similarity among scene objects ...

There is evidence that people with social anxiety show abnormal processing of emotional faces. To investigate the impact of top-down prediction on emotional face processing in social anxiety, brain responses of participants with high and low social anxiety (LSA) were recorded, while they performed a variation of the emotional task, using high temporal resolution event-related potential techniqu...

ABSTRACT Since users are faced with an ever increasing amount of data, fast and effective retrieval of required information is of vital importance. This study examined two methods of using Latent Semantic Analysis (LSA) to improve the results retrieved using a keyword-based technique using sentence or document context. Fifty participants retrieved information using a standard keyword technique ...
