With the diffusion of digital information technology, data mining (DM) is widely expected to increase the productivity of all kinds of research activities. Based on bibliometric data, we demonstrate that the share of DM-related research articles in all published academic papers has increased substantially over the last two decades. We develop an ordinal categorization of countries according to ...

These articles raise two sets of issues. One involves the scientific status of research on this topic, and the other involves concerns about law, social policy, and civil rights. My comments focus on both sets of issues, be...

Competition between two populations tends to eliminate one of the populations from their common habitat, when competition is focused on a single resource and when the populations do not otherwise interact. It is known that two microbial species competing for a single rate-limiting nutrient cannot grow together in a chemostat under steady-state operation, but eventually the species with the lowe...

OBJECTIVE The objective of this study is to make a comparative description of the evolution and distribution of international research into pharmacoepidemiology, using three bibliographic databases, in order to select the most appropriate for future bibliometric studies. METHODS Bibliographic searches were performed using the following databases: Medline (1966-99), IPA (1970-99) and SCI (1990...

The use of social science—of psychology in particular—to inform legal theory and practice is fast becoming the latest craze in the pages of legal academia. Books and symposia have recently been devoted to the interplay between psychology and law and between emotions and the law, and to the application of other psychological and social scientific research to legal questions. An increasing number...

We report a simple stepped growth process for the synthesis of carbon nanotubes (CNTs) having excellent field emission properties. CNT growth was interrupted in the process. During the interruption, the catalyst was re-activated in-situ. This resulted in enhanced growth of the CNTs after the interruption and a film of CNTs re-grew on top of an existing CNT film at much higher rates. The enhance...

one of the issues in the field of inheritance is the inheritance of credential-right by the wife from the husband’s trades. unfortunately, iranian statute law has not specified this verdict, and article 445 of civil law merely states that: ‘each of the credentials, after death, is transferred to the heir.’ although the ruling is applicable to the mentioned article regarding the inheritance of c...
