The reprint that follows this introduction is the second part of an articlel published in Theoretical Medicine by myself and Alfred Welljams-Dorof, my scientific assistant at the Institute for Scientific Information@’(ISF’). The paper addresses an interesting point that has been explored in previous Current Comments@ essays: Do quantitative rankings of highly cited authors confirm-and even anti...

This study examines the completeness and overlap of coverage in physics of six open access scholarly communication systems, including two search engines (Google Scholar and Microsoft Academic), two aggregate institutional repositories (OAIster and OpenDOAR), and two physics-related open sources (arXiv.org and Astrophysics Data System). The 2001-2013 Nobel Laureates in Physics served as the samp...

Despite the huge literature on h-index, few papers have been devoted to the statistical analysis of -index when a probabilistic distribution is assumed for citation counts. 2 The present contribution relies on showing the available inferential techniques, by providing the details for proper point and set estimation of the theoretical . Moreover, some 2-index issues on simultaneous inference aim...

In this review we give an overview of the field of Computational enzymology. We start by describing the birth of the field, with emphasis on the work of the 2013 chemistry Nobel Laureates. We then present key features of the state-of-the-art in the field, showing what theory, accompanied by experiments, has taught us so far about enzymes. We also briefly describe computational methods, such as ...

Data on Nobel Laureates show that the age-creativity relationship varies substantially more over time than across fields. The age dynamics within fields closely mirror field-specific shifts in (i) training patterns and (ii) the prevalence of theoretical contributions. These dynamics are especially pronounced in physics and coincide with the emergence of quantum mechanics. Taken together, these ...

Three researchers share this year ́s Nobel Prize in Chemistry: Dr. Yves Chauvin at the Institut Français du Pétrole, Rueil-Malmaison, France; Professor Robert H. Grubbs, California Institute of Technology, Pasadena, California, USA and Professor Richard R. Schrock, Massachusetts Institute of Technology, Cambridge, Massachusetts, USA. The Royal Swedish Academy of Sciences citation runs “for the d...

The twentieth century saw dramatic international shifts in scientific leadership. Despite these dramatic shifts Britain’s position has been remarkably stable and strong. I study these changes using data on Nobel laureates in Chemistry, Medicine, and Physics. Raw data show a slight decline in British science, mainly in physics but once one accounts for the tremendous increase in the US, British ...
