In river deltas, human interference with regional and global socio-ecological systems has led to a plethora of gradual more abrupt environmental changes that result in inundation, coastal bank erosion, land loss and, ultimately, displaced people. Often apolitically framed as protective, state-led transfer people new housing grounds, resettlement become common response such displacements. its pr...

Deltas worldwide are at risk of elevation loss and drowning due to relative sea-level rise. Management strategies restore or enhance sedimentation on delta plains, Sedimentation-Enhancing Strategies (hereafter SES), now being pursued in many deltas but there has been limited cross-disciplinary cross-delta review. Here we compare 21 existing planned SES, synthesizing their physical characteristi...

RDF is widely used in the Semantic Web for representing ontology data. Many real world RDF collections are large and contain complex graph relationships that represent knowledge in a particular domain. Such large RDF collections evolve in consequence of their representation of the changing world. Although this data may be distributed over the Internet, it needs to be managed and updated in the ...

For an integer n ≥ 3, the clutter ∆n := { {1, 2}, {1, 3}, . . . , {1, n}, {2, 3, . . . , n} } is called a delta of dimension n, whose members are the lines of a degenerate projective plane. In his seminal paper on non-ideal clutters, Alfred Lehman manifested the role of the deltas as a distinct class of minimally non-ideal clutters [DIMACS, 1990]. A clutter is delta free if it has no delta mino...

Reactions A(γ, πp) are considered to proceed through the formation of πp pairs on ∆ constituents in nuclei. We develop the nonrelativistic operator of γ∆ → πp process in an arbitrary frame. The calculated cross section of C(γ, πp) reaction is compared to the existing experimental data. The role of isobars as nuclear constituents was a topic of a large body of research over a long time (a compre...

Channel systems at the distal limits of submarine fans show variability in channel size and bifurcation patterns. This information is useful in constraining channel properties in static reservoir models, e.g. the mean and range of values typical for channel dimensions, sinuosity, and branching angles. Criteria were evaluated that might help discriminate between deltas and submarine fans based o...
