When a small microphone is fitted into an ear canal, one might find that the sound picked up by the microphone would consist of more than just background noise. These detectable sound emissions generated from the inner ear have been named spontaneous otoacoustic emissions or SPOAEs since their discovery by a British engineer named David Kemp in 1977. Since their discovery, otoacoustic emissions...

Led by David Cella, Ph.D., at Evanston Northwestern Healthcare and Northwestern University's cancer center in Chicago, the study confirms not only that cancer-related fatigue is common but also that it affects pati...

Research collaboration can bring in different perspectives and generate more productive results. However, finding an appropriate collaborator can be difficult due to the lacking of sufficient information. Link prediction is a related technique for collaborator discovery; but its focus has been mostly on the core authors who have relatively more publications. We argue that junior researchers act...

Nursing science addresses the individual from a multidimensional perspective, and the questions nurses generate from their practice are often grounded in basic biology. However, concern is frequently voiced as to whether there is adequate preparation and support for biological researchers within nursing. This study reports on a survey of nurse investigators funded by the National Institutes of ...

Learning statistics is a necessity for dental researchers. Due to daily dental science expansion, dental researchers have to study new papers in recent dental journals to remain up to date. On the other hand, knowing principles of statistics helps better understanding of the articles. Some authors revealed that knowledge of dentists about basic topics of statistics was poor. Therefore, in this ...
