The Africa Program achieves its mission through in-depth research that offers practical solutions to key challenges in US-Africa relations. The Africa Program's flagship initiatives include the ...

For nearly a century, continuing to the present, a complete accounting of the excitation of the Chandler wobble (CW), a resonant motion of Earth’s rotation axis, has been a major scientific goal. We ...

Current tests of hearing fail to diagnose pathologies in ~10% of patients seeking help for hearing difficulties. Neural ensemble responses to perceptually relevant cues in the amplitude envelope, ...

A series of our previous studies explored the use of an abstract visual representation of the amplitude envelope cues from target sentences to benefit speech perception in complex listening ...

Different types of modulation techniques are used in telecommunication for transmitting and receiving radio frequency (RF) signals. With MATLAB tools we can analyse the modulation techniques used for ...

Patterns in external sensory stimuli can rapidly entrain neuronally generated oscillations observed in electrophysiological data. Here, we manipulated the temporal dynamics of visual stimuli with ...

Recent studies have shown that direct nerve stimulation can be used to provide sensory feedback to hand amputees. The intensity of the elicited sensations can be modulated using the amplitude or ...

Acoustic communication is critical for underwater application such as deep-ocean scientific explorations and off-shore industrial controls. This is because other techniques using electromagnetic waves ...

The conversion between multiple- and single-quantum coherences is integral to many nuclear magnetic resonance (NMR) experiments of quadrupolar nuclei. This conversion is relatively inefficient when ...
