Abstract Hydrological and sedimentological data were collected on several cross-sections of both natural artificial canals three cutoff meanders (Mahmudia, Dunavăţul de Sus, Jos meanders) the Sfântu Gheorghe branch at beginning June 2017. The hydrological shows a heterogeneous distribution water discharges: Mahmudia Jos, most liquid flow passes through channels. In case Sus meander, cut meander...

Reservoir architecture is an important basis for studying the sedimentary evolution of underground reservoirs and distribution remaining oil. Taking meander-river reservoir Guantao Formation in Chengdao Oilfield as example, characteristics subsurface meander-belt deposits were studied by seismic sedimentology. Seismic lithology performed using -90° phase wavelet frequency fusions; geomorphology...

We report on the effect of anisotropy on the step meandering instability on vicinal surfaces during molecular beam epitaxy growth. A scenario of interrupted coarsening is found: the lateral length scale of the structure first significantly increases with time and then freezes at a larger length scale. The wavelength selection mechanism results from a nontrivial nonlinear effect of anisotropy. A...

Lemniscates are level curves of the absolute value of univariate complex polynomials. We consider the approximation of meander-like regions (i.e., regions similar to meandering rivers) by pairs of confocal lemniscates that are stitched together continuously. We look at orthogonal grids on these types of plane regions. The main application is in the area of numerical solution of partial differen...

Previously we observed that stable clones of multipotent neural progenitor cells, initially isolated and propagated from the external granular layer of newborn wild-type mouse cerebellum, could participate appropriately in cerebellar development when reimplanted into the external granular layer of normal mice. Donor cells could reintegrate and differentiate into neurons (including granule cells...
