Dear Sir: We read with interest the recent article by Shepard and others, 1 which attempted to evaluate the impact of human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) funding on Rwanda's health system. The headline of the associated press release is assertive: " Six-Year Study in Rwanda Finds Influx of HIV/AIDS Funding Does Not Undermine Health Care Services for Other ...

The endless scale illusion, obtained by cyclically repeating a chromatic scale made up of Shepard tones, has been used in a variety of musical works. Music psychology and neuroscience has been interested in this particular psychoacoustic phenomenon mainly for studying the cognitive processes of pitch perception involved. In the present study, we investigated the emotional states induced by the ...

Abstract In this paper, we construct the complex Shepard operators to approximate continuous and complex-valued functions on unit square. We also examine effects of regular summability methods approximation by these operators. Some applications verifying our results are provided. To illustrate theorems graphically consider real or imaginary part function being approximated use contour lines mod...

This commentary centers on the novel findings by Shepard et al. (2016) published in eNeuro. The authors interrogated tonotopic map dynamics in auditory cortex (ACtx) by employing a natural sound-learning paradigm, where mothers learn the importance of pup ultrasonic vocalizations (USVs), allowing Shepard et al. to probe the role of map area expansion for auditory learning. They demonstrate that...
