The U-space Concept [PDF]

open access: bronzeAir and Space Law, 2019
The integration of civil unmanned aircraft systems (drones) into airspace has turned out to be a real challenge. Drones have difficulties in following many of the rules designed for manned aviation, because drones are plentiful and cheap, because they have no pilot on board, and because they are often flown at a very low altitude.

U-Space Social and Environmental Performance Indicators

open access: yesDrones
The social potential of Urban Air Mobility (UAM) as a greener and faster transportation system in and around urban environments is indisputable. Nevertheless, the success of UAM introduction and its wide use will strongly depend on acceptance by the ...

On the space of U(N) scattering amplitudes [PDF]

open access: diamondJournal of High Energy Physics
We investigate the space of massive two-dimensional theories with a global U(N) symmetry and no bound states. Following S-matrix bootstrap principles, we establish rigorous bounds on the space of consistent 2 → 2 scattering amplitudes.

Remarks on monotonically star compact spaces [PDF]

open access: yesMathematica Bohemica, 2022
A space $ X $ is said to be monotonically star compact if one assigns to each open cover $ \mathcal{U} $ a subspace $ s(\mathcal{U}) \subseteq X $, called a kernel, such that $ s(\mathcal{U}) $ is a compact subset of $ X $ and $ {\rm St}(s(\mathcal{U ...

On the importance of neutral composition and temperature measurements in the 100–200 km altitude region

open access: yesFrontiers in Astronomy and Space Sciences, 2022
Currently, thermospheric species densities and temperatures between ∼100 and 200 km are not known to the accuracy needed to fully characterize how the thermosphere transitions from a well-mixed atmosphere to a diffusively separated atmosphere with zero ...
