How Have Cancer Clinical Trial Eligibility Criteria Evolved Over Time?

Knowledge reuse of cancer trial designs may benefit from a temporal understanding of the evolution of the target populations of cancer studies over time. Therefore, we conducted a retrospective analysis of the trends of cancer trial eligibility criteria between 1999 and 2014. The yearly distributions of eligibility concepts for chemicals and drugs, procedures, observations, and medical conditio...

How Could Language Have Evolved?

The evolution of the faculty of language largely remains an enigma. In this essay, we ask why. Language's evolutionary analysis is complicated because it has no equivalent in any nonhuman species. There is also no consensus regarding the essential nature of the language "phenotype." According to the "Strong Minimalist Thesis," the key distinguishing feature of language (and what evolutionary th...

LSDBs and How They Have Evolved.

Locus specific databases (LSDBs) make a key contribution to our understanding of heritable and acquired human disorders, disease susceptibility, and adverse drug reactions. As data have accumulated in LSDBs, a greater reliance on their use has arisen in clinical practice. Even though LSDBs have existed in recognizable form for only a quarter of a century, their origin lies in the manual catalog...

Trends in Global Tropical Cyclone Activity over the Past Twenty Years (1986-2005)

5) Two metrics were evaluated to determine trends over the past twenty years. The first metric is the Accumulated Cyclone Energy (ACE) index, which is the maximum sustained wind speed squared at six-hour intervals. ACE represents an approximation of the kinetic energy generated by a tropical cyclone. ACE correlates globally at 0.97 with Emanuel’s PDI index which is the wind speed cubed at six-h...
