No full textTwo-photon excitation for Optical Nanoscopy and Light-Sheet Illumination Microscopy
No full textWe report about coupling two-photon excitation (2PE) with two, comparatively young and successful optical methods specially realized for the improvement of resolution and 3D imaging of large samples, i.e. STED
(stimulated emission depletion) and SPI (selective plane illumination) microscopy. In the former case we aimed to get a better resolution for 2PE microscopy while for the latter we aimed to obtain better penetration in scattering samples by shifting the light sheet wavelengths to the red in the non-linear domain. We show results obtained by adapting a commercial STED-CW microscope to 2PE and by implementing a 2PE-SPIM homemade system. The implementation of these systems is demonstrated by the imaging of living Saccharomyces cervisiae cells
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
