Risky Traitor Tracing and New Differential Privacy Negative Results
Traitor Tracing Differential Privacy
2017/11/27
Finally, we can capture impossibility results for differential privacy from risky traitor tracing. Since our ciphertexts are short (O(λ)O(λ)), thus we get the negative result which matches what one wo...
Humans identify negative (but not positive) arousal in silver fox vocalizations: Implications for the adaptive value of interspecific eavesdropping
eavesdropping emotional arousal emotional valence
2017/8/28
The ability to identify emotional arousal in heterospecific vocalizations may facilitate behaviors that increase survival opportunities. Crucially, this ability may orient inter-species interactions, ...

Negative feedback loops help maintain function of mutated proteins
Negative feedback loops maintain function mutated proteins
2016/7/4
Negative feedback is a universal control mechanism that lets a system’s output throttle its input. If an engine revs up, negative feedback tapers its power source. But if the engine slows down, it re-...
