Joint Resource Optimization Over Licensed and Unlicensed Spectrum in Spectrum Sharing UAV Networks Against Jamming Attacks
Unmanned aerial vehicle (UAV) communication is of crucial importance in realizing heterogeneous practical wireless application scenarios. However, the densely populated users and diverse services with high data rate demands has triggered an increasing scarcity of UAV spectrum utilization. To tackle this problem, it is promising to incorporate the underutilized unlicensed spectrum with the licensed spectrum to boost network capacity. However, the openness of unlicensed spectrum makes UAVs suscep…

"In old times, and also in our time among the Indian tribes, psychedelic substances were considered sacred and they were used with the right attitude and in a ritual and spiritual context. And what a difference if we compare it with the careless and irresponsible use of LSD in the streets and in the discotheques of New York City and everywhere in the West. It is a tragic misunderstanding of the nature and the meaning of these kinds of substances."
— Albert Hofmann

John Coltrane's "Practice Buddies," From Benny Golson to Pat DeRosa
Here’s something kind of endearing about John Coltrane (1926-1967) that has never been discussed: He liked to practice with another musician, usually a saxophonist.

«The original paper confidently and without discussion labelled millions of tweets based on what Dave (and some others) said about the website in the tweet, but the original authors have almost certainly never heard of Dave. […] Dave's opinions must take on a form totally independent of Dave, because the original authors would never have taken this dataset seriously had it been presented as "Dave's thoughts on media." This is the spectacle of computation.»

Improved Quantum Sensing by Spectral Design
We investigate how unitary control can improve parameter estimation by designing the effective spectrum of the imprinting Hamiltonian. We show that, for commuting Hamiltonians, the general problem of spectral manipulation via unitary control simplifies to a finite sequence of elementary switching operations. Furthermore, we demonstrate that any desired relative spacing of energy levels can be achieved. We also show that any modified spectrum can be expressed as a convex combination of the origi…

A note on Duality and the Atiyah-Hirzebruch spectral sequence
We show that, for a finite spectrum $X$, the Spanier-Whitehead duality isomorphism induces an isomorphism between the cohomological and homological Atiyah-Hirzebruch spectral sequences. As an application, it follows that Poincaré duality for a Poincaré duality complex, which is oriented over a ring spectrum $E$, induces an isomorphism between the two spectral sequences.
