Galileo Magnetometer Measurements: A Stronger Case for a Subsurface Ocean at Europa
Margaret G. Kivelson,Krishan K. Khurana,Christopher T. Russell,Martin Volwerk,Raymond J. Walker,Christophe Zimmer +5 more
TL;DR: The Galileo magnetometer measured changes in the magnetic field predicted if a current-carrying outer shell, such as a planet-scale liquid ocean, is present beneath the icy surface of Europa.
Measurements: A Stronger Case for a Subsurface Ocean at Europa
Margaret G. Kivelson,Krishan K. Khurana,Christopher T. Russell,Martin Volwerk,Raymond J. Walker,Christophe Zimmer +5 more
TL;DR: In 2000, the Galileo spacecraft passed close to Europa when it was located far south of Jupiter's magnetic equator in a region where the radial component of the magnetospheric magnetic field points inward toward Jupiter as discussed by the authors.
Journal ArticleDOI
SAGA interacting factors confine sub-diffusion of transcribed genes to the nuclear envelope
Ghislain G. Cabal,Auguste Genovesio,Susana Rodríguez-Navarro,Susana Rodríguez-Navarro,Christophe Zimmer,Olivier Gadal,Annick Lesne,Henri Buc,Frank Feuerbach-Fournier,Jean-Christophe Olivo-Marin,Eduard C. Hurt,Ulf Nehrbass +11 more
TL;DR: It is demonstrated that the GAL locus is subject to sub-diffusive movement, which after activation can become constrained to a two-dimensional sliding motion along the nuclear envelope, which is in accordance with the ‘gene gating’ hypothesis.
Journal ArticleDOI
QuickPALM: 3D real-time photoactivation nanoscopy image processing in ImageJ
Ricardo Henriques,Ricardo Henriques,Mickaël Lelek,Eugenio F. Fornasiero,Flavia Valtorta,Christophe Zimmer,Musa M. Mhlanga,Musa M. Mhlanga +7 more
TL;DR: To the Editor: Although conventional microscopes have a reso-lution limited by diffraction to about half the wavelength of light, several recent advances have led to microscopy methods that achieve roughly tenfold improvements in resolution.
Journal ArticleDOI
Richardson-Lucy algorithm with total variation regularization for 3D confocal microscope deconvolution.
Nicolas Dey,Laure Blanc-Féraud,Christophe Zimmer,Pascal Roux,Zvi Kam,Jean-Christophe Olivo-Marin,Josiane Zerubia +6 more
TL;DR: This work proposes to combine the Richardson–Lucy algorithm with a regularization constraint based on Total Variation, which suppresses unstable oscillations while preserving object edges and shows that this constraint improves the deconvolution results as compared with the unregularized Richardson– Lucy algorithm, both visually and quantitatively.
