Embedded contact knot homology and a surgery formula
… of the manifold. As part of their proof that ECH=HF, Colin, Ghiggini and Honda showed that if the contact form is suitably adapted to an open book decomposition of the manifold, then embedded contact homology can be computed by considering only orbits and differentials in the complement of the …

Phase contrast imaging measurements and modeling of short wavelength turbulence in the DIII-D tokamak
… at angles as large as kII/k ~ 0.1 - 0.4. ECH heating is observed to increase the spectral power density in the high-k mode (-24 < k < -18 cm-1), and the parallel wave-numbers are measured to be as large as kII/k ~ 0.15. The applied heating is shown to increase the electron temperature …
