The model predicts a new coupling mode in chiral nanotubes – coupling between twist and cross-sectional shrinkage implying that the three deformation modes (extension, twist and cross-sectional shrinkage) are all coupled to each other.
The functions, called Hough Mode Extensions, maintain self-consistent internal relationships between winds, densities and temperatures, and account for changes in vertical and latitudinal shape within the dissipative thermosphere.
In this paper, we will refer to and utilize Hough mode extensions (HMEs) and the Climatological Model of Thermosphere Tides (CTMT) in the interpretation of results.
We also employ Hough mode extensions (HMEs) and the Climatological Model of Thermosphere Tides (CTMT) to ascertain whether the observed structures are consistent with those observed at 110 km and presented in part 1 of this study.
Remarkably, the mode extension of the studied guiding structures can be readily controlled by varying their transverse dimensions, which gives us an intuitive and simple method for tailoring the antenna directivity.
AdGuard, which developed the Stealth Mode extension for the browser, has also published its source code on Github.
This is based on Hough Mode Extension fits to 2002 2008 TIMED satellite tidal diagnostics in the lower thermosphere.
The mode selection is optimized through neighbor mode extension and adapted cost function that takes into account both the most appearing modes and those with higher gradient magnitudes.
A Hough mode extension represents the global solution (pole-to-pole, 0- to 400-km altitude) to the linearized dynamical equations of the atmosphere for an oscillation of a given frequency and zonal wavenumber, taking into account dissipative effects (i.e., radiative cooling, eddy and molecular diffusion of heat and momentum) above the forcing region.
To address systems with complex modes, various extension approaches have been proposed, in particular: (a) Using a first-order state-space formulation for the system dynamics; (b) Building complex analytic signals from the measured responses using the Hilbert transform.
