M3Fusion: A Deep Learning Architecture for Multi-{Scale/Modal/Temporal} satellite data fusion
Modern Earth Observation systems provide sensing data at different temporal
and spatial resolutions. Among optical sensors, today the Sentinel-2 program
supplies high-resolution temporal (every 5 days) and high spatial resolution
(10m) images that can be useful to monitor land cover dynamics. On the other
hand, Very High Spatial Resolution images (VHSR) are still an essential tool to
figure out land cover mapping characterized by fine spatial patterns.
Understand how to efficiently leverage these complementary sources of
information together to deal with land cover mapping is still challenging. With
the aim to tackle land cover mapping through the fusion of multi-temporal High
Spatial Resolution and Very High Spatial Resolution satellite images, we
propose an End-to-End Deep Learning framework, named M3Fusion, able to leverage
simultaneously the temporal knowledge contained in time series data as well as
the fine spatial information available in VHSR information. Experiments carried
out on the Reunion Island study area asses the quality of our proposal
considering both quantitative and qualitative aspects

Semiautomated evaluation of the primary motor cortex in patients with amyotrophic lateral sclerosis at 3t
Amyotrophic lateral sclerosis is a neurodegenerative disease involving the upper and lower motor neurons. In amyotrophic lateral sclerosis, pathologic changes in the primary motor cortex include Betz cell depletion and the presence of reactive iron-loaded microglia, detectable on 7T MR images as atrophy and T2*-hypointensity. Our purposes were the following: 1) to investigate the signal hypointensity-to-thickness ratio of the primary motor cortex as a radiologic marker of upper motor neuron involvement in amyotrophic lateral sclerosis with a semiautomated method at 3T, 2) to compare 3T and 7T results, and 3) to evaluate whether semiautomated measurement outperforms visual image assessment

Microstructural and mechanical characterization of welded joints on innovative high-strength steels
INTRODUCTION In recent years car-bodies are more and more frequently constructed with innovative high-strength steels, both to reduce the vehicles weight and to improve the passenger safety. The main requirements for these steels in service are high fracture strength and good energy absorption, in relation to the possibility of the automobile accidents, and good fatigue resistance, relatively to the normal use of vehicle
