The patient presented with complete weakness of the right upper and lower extremities at the onset of intracerebral hemorrhage; however, he showed progressive motor recovery to the level that he was able to extent the affected extremities against some resistance at 5 weeks after onset. The corticospinal tract of the affected （left） hemisphere connected to the left Broca＇s area at 3 weeks after onset as shown by diffusion tensor tractography. By contrast, this connection had disappeared at 5 weeks after onset as shown by diffusion tensor tractogaphy. Transcranial magnetic stimulation study showed that no motor evoked potential was elicited from the affected （left） hemisphere at 3 weeks after onset, but motor evoked potentials were elicited at 5 weeks after onset. These findings suggest that the connection between the injured corticospinal tract and Broca＇s area in this patient appears to be a compensation for severe motor weakness; consequently, the connection seems to disappear with motor recovery.展开更多

This contribution gives for the first time a comparative study considering the recovery of the global gravity field from three constellations flying in satellite pairs in different directions (i.e. along-track, cross-track and radial). The three constellations include: 1) Foursatellite Bender configuration (flying in two pairs) of type along-track observations, 2) Three-satellite GRAPEN (combined GRACE with Pendulum formations) configuration of type cross-alongtrack observations, 3) Four-satellite Cartwheel configuration (flying in two pairs) of type radialalong-track observations. Additionally, a GRACE mission scenario is added as a reference “comparative” mission. The orbits of all satellites are considered to fly with drag-free system, however, realistic white noise has been added to the simulated observations to mimic the error associated with the drag-free measurement. The results are analyzed in the spectral wavelength spectrum of the gravity field up to a spherical harmonics degree of n = 100 and are plotted spatially on earth maps. The results show that the Three-satellite GRAPEN constellation provides, besides its low economically launches, an improved gravity field solution with respect to the Four-satellite Bender and the Four-satellite Cartwheel constellations.展开更多
