Frozen Footprints
Bibliometrics has the ambitious goal of measuring science. To this end, it exploits the way science is disseminated trough scientific publications and the resulting citation network of scientific papers. We survey the main historical contributions to the field, the most interesting bibliometric indicators, and the most popular bibliometric data sources. Moreover, we discuss distributions common...
متن کاملFlux and concentration footprints
This special issue is comprised primarily of papers presented at 3rd INTAS (International Association for the promotion of co-operation with scientists from the New Independent States of the former Soviet Union) workshop on ‘‘Flux and Concentration Footprints’’ held at the Hyytiälä Forestry Field Station in Juupajoki, Finland. The workshop attracted scientists from ten countries and it was the ...
متن کاملAnthropogenic footprints on biodiversity
One of the most concerning issues to modern ecology and society is the ongoing loss of biodiversity. Ecosystems are now losing species at rates only seen in previous mass extinction events (Hails, 2008; Barnosky et al., 2011) with rates of extinction between 100 and 1000 times higher than pre-human levels (Pimm et al., 1995). This loss, in turn, is impairing the functioning of ecosystems (Worm ...
متن کاملFootprints in Local Reasoning
Local reasoning about programs exploits the natural local behaviour common in programs by focussing on the footprint that part of the resource accessed by the program. We address the problem of formally characterising and analysing the footprint notion for abstract local functions introduced by Calcagno, O’Hearn and Yang. With our definition, we prove that the footprints are the only essential ...
متن کاملConformational dynamics of di-(perylene bisimide acrylate) and its footprints in steady-state, time-resolved, and fluorescence-correlation spectroscopy.
Employing steady-state spectroscopy, time-resolved fluorescence spectroscopy, and fluorescence (cross-) correlation spectroscopy we investigated di-(perylene bisimide acrylate) and compared the results with those from monomeric perylene bisimide acrylate. For the dimeric structure two emitting species were found. By comparison with the spectroscopic results from monomeric perylene bisimide one ...
