Analysis and Control of a Variable-Pitch Quadrotor for Agile Flight

open access: yes, 2015
Fixed-pitch quadrotors are popular research and hobby platforms largely due to their mechanical simplicity relative to other hovering aircraft. This simplicity, however, places fundamental limits on the achievable actuator bandwidth and the possible ...

Attending to Pitch Information Inhibits Processing of Pitch Information: The Curious Case of Amusia

open access: yesJournal of Neuroscience, 2015
In normal listeners, the tonal rules of music guide musical expectancy. In a minority of individuals, known as amusics, the processing of tonality is disordered, which results in severe musical deficits.

A Hierarchical Bayesian Model of Pitch Framing

open access: yes, 2017
Since the advent of high-resolution pitch tracking data (PITCHf/x), many in the sabermetrics community have attempted to quantify a Major League Baseball catcher's ability to "frame" a pitch (i.e.

Pitch Angle Restrictions in Late Type Spiral Galaxies Based on Chaotic and Ordered Orbital Behavior

open access: yes, 2011
We built models for low bulge mass spiral galaxies (late type as defined by the Hubble classification) using a 3-D self-gravitating model for spiral arms, and analyzed the orbital dynamics as a function of pitch angle, going from 10$\deg$ to 60$\deg ...

Urgency is a Non-monotonic Function of Pulse Rate [PDF]

open access: yes, 2007
Magnitude estimation was used to assess the experience of urgency in pulse-train stimuli (pulsed white noise) ranging from 3.13 to 200 Hz. At low pulse rates, pulses were easily resolved.

Increased volume and function of right auditory cortex as a marker for absolute pitch.

open access: yesCerebral Cortex, 2014
Absolute pitch (AP) perception is the auditory ability to effortlessly recognize the pitch of any given tone without external reference. To study the neural substrates of this rare phenomenon, we developed a novel behavioral test, which excludes memory ...
