One of the most striking ecological divides on Earth is between marine and nearby freshwater environments, as relatively few taxa can move two. Microbial eukaryotes contribute to biogeochemical energy cycling in both fresh waters, with little species overlap two ecosystems. Arctic sub-Arctic systems are compared tropical temperate systems, but details microbial eukaryote communities along river...

Transition zones between embankments and bridges or tunnels are examples of critical assets the railway infrastructure. These locations often exhibit higher degradations rates, mostly due to development differential settlements, which amplify dynamic train-track interaction, thus further accelerating settlements deteriorating track components vehicles. Despite technical scientific interest in p...

PURPOSE To study retinal microstructure in Usher Syndrome type 1B (USH1B) caused by MYO7A mutations as a prelude to treatment initiatives. METHODS Patients with MYO7A-USH1B (n=17; ages 5-61) were studied with optical coherence tomography. Retinal laminae across horizontal and vertical meridians were measured. Colocalized visual sensitivity was measured with automated perimetry to enable compa...

Discussion The spine is considered as an heterogeneous beam, and is modeled as a deformable wire, along which vertebrae are beads rotating about the wire. Each vertebra can rotate about the 3D spinal curve. 3D spinal curves are compound of plane regions connected together by zones of transition. The 3D spinal curve is uniquely flexed along the plane regions. The angular offsets between adjacent...

The Earth stands out in the solar system as the only planet with plate tectonics. This peculiarity is due not only to strong internal heating but also a lithosphere rheology characterized by brittle failure and localization, as a comparison with Venus clearly show. Localization in the ductile regime are manifested on Earth by ductile shear zones, which have proven difficult to explain theoretic...
