experiment in which a survey of AI and expert systems (ES) literature was attempted using Science Citation Indexes The survey identified a sample of authors and institutions that have had a significant impact on the historical development of AI and ES However, it also identified several glaring problems with using Science Citation Indexes as a method of comprehensively studying a body of scient...

FefCo multilayered films with about 3 000 A thick have been deposited by an opposed targets sputtering apparatus. The films with deposition period dlayer above 10 A have layered structure. Their magnetic properties changes significantly with dl, and the film with dlayer around 60 A has the lowest coercive force of about 6 Oe and saturation magnetization about 1 600 emufcc.

In this paper, we provide an ex-ante explanation for why some technologies such as James Watt’s steam engine move successfully across broad technological fields, while other technologies do not. Using a sample of VC-backed biotechnology firms, we examine firm knowledge exploration choices along three dimensions—the decision to build from technologies across broad fields, the decision to explore...

BACKGROUND Violence against women has been associated with subsequent risky sexual behaviors and sexually transmitted infections (STIs). We explored whether sexual coercion or violence at first intercourse was associated with self-reported STIs. METHODS Using nationally representative data from the 2006 to 2010 National Survey of Family Growth, we analyzed female respondents aged 18 to 44 (n ...

Five doped nanosized spinel ferrites were synthesized using the dicarboxylate and hydroxide coprecipitation method. XRD of samples confirmed increase in lattice parameters as compared to undoped samples. Decrease saturation magnetization coercive force are found these
