Otto Werner originally defined Werner syndrome (WS) in 1904 on the basis of sclerodermalike, thin, tight skin and bilateral cataracts. WS is also known as progeria adultorum, progeria of the adult, and pangeria.
There is no difference between the terms 'paper' and 'article'. A research paper is one where an original study has been performed. A review paper may be either a narrative review, a systematic review or a meta-analysis. A narrative review is like a book chapter: it explains a topic in detail based on previously published research.
The connection here, then, is that a research paper differs from an essay in that the research takes the spotlight here. So while the essay focuses on your analysis of the topic and supports that analysis with research, the research paper focuses on the sources and the conclusions that can be drawn from them. In this case, you are the vehicle for the research rather than the research being the vehicle for your ideas.
