[1] Mantle dynamics can strongly affect melting processes beneath spreading centers and volcanic arcs. A 2-D numerical model of the Tonga subduction zone, with the slab viscously coupled to the mantle beneath the brittleductile transition but faulted above, shows that induced corner flow may cause asymmetric melting at the Lau backarc spreading center, 400 km away. The down-going slab also entr...

Communities in spatially fragmented deep-sea hydrothermal vents rich in polymetallic sulfides could soon face major disturbance events due to deep-sea mineral mining, such that unraveling patterns of gene flow between hydrothermal vent populations will be an important step in the development of conservation policies. Indeed, the time required by deep-sea populations to recover following habitat...

This paper demonstrates a biologicallyand psychologicallyinspired human-like computational memory focusing on the retrieval mechanisms – Spreading Activation and Compound Cue for a companion agent’s episodic memory (EM) that helps the agent to manage it’s memory more efficiently and enable it to have a more natural interaction with the user.

flood spreading has an effective role in the soil improvement and fertility, ground water storage, revival of vegetation and prevention of fluent sands movement. one of the main problem of flood spreading projects is the entrance of sediment to the spreading systems and sedimentation in it. sediment reduces the efficiency of the flood spreading system and after awhile lose its efficiency.the ma...

So far, the natural recovery of vent communities at large scales has only been evaluated fast spreading centers, by monitoring faunal recolonisation after volcanic eruptions. However, slow ridges, opportunities to observe disturbances are rare, overall hydrothermal system being more stable. In this study, we implemented a novel experimental approach inducing small-scale disturbance assess poten...

cortical spreading depression (csd) are associated with dramatic failure of brain ion homeostasis, efflux of excitatory amino acids from nerve cells, increased energy metabolism and changes in cerebral blood flow. there is strong clinical and experimental evidence to suggest that csd is involved in the mechanism of migraine, stroke, subarachnoid hemorrhage and traumatic brain injury. therefore,...

objective headache is a frequent symptom in children and adolescents. migraine is one of the most common types of primary headache disorders in children that at times can be extremely disabling. many clinical features of migraine in children differ from that starting in adulthood. this review discusses the epidemiology,clinical features, management, and prognosis of migraine headache in childre...
