A significant fraction of the Eulerian-mean downwelling feeding lower limb Atlantic Meridional Overturning Circulation (AMOC) occurs along subpolar North continental slopes and is maintained by along-boundary densification large-scale geostrophic balance. We here use Argo shipboard hydrography data to map 2002–2015 long-term mean density field boundary via a dedicated optimal interpolation tool...

Climate change has recently been implicated in poleward shifts of many tropical species including corals; thus attention focused on higher-latitude coral communities is warranted to investigate possible range expansions and ecosystem shifts due to global warming. As the northern extension of the Florida Reef Tract (FRT), the third-largest barrier reef ecosystem in the world, southeast Florida (...

Located in northeastern Algeria, the region of Constantinois is undoubtedly among regions most affected by various risks related to rail networks. These phenomena are one major development issues and a permanent threat population existing facilities. The associated with field transport several parameters such as soft geological formations, steep slopes, hydrographic network, seismic frame mainl...

In this paper we use a two-layer neural network for robust image segmentation. The rst layer is a locally coupled recurrent network. Using probabilistic measures, contextual information is incorporated eeectively through underlying coupling structures, which reduces and even resolves local ambiguities in images. The second layer is a LEGION (Locally Excitatory Globally Inhibitory Oscillator Net...

The SIM-DL theory has been developed to enable similarity measurement between concept specifications using description logics. It thus closes the gap between similarity theories from psychology and formal representation languages from the AI community, such as the Web Ontology Language (OWL). In this paper, we present the results of a human participants test which investigates the cognitive pla...

Decadal changes of abyssal temperature in the Pacific Ocean are analyzed using high-quality, full-depth hydrographic sections, each occupied at least twice between 1984 and 2006. The deep warming found over this time period agrees with previous analyses. The analysis presented here suggests it may have occurred after 1991, at least in the North Pacific. Mean temperature changes for the three zo...
