Structure of international trade hypergraphs
Sudo Yi, Deok-Sun Lee
We study the structure of the international trade hypergraph consisting of triangular hyperedges representing the exporter-importer-product relationship. Measuring the mean hyperde…
Heterogeneous popularity of metabolic reactions from evolution
Mi Jin Lee, Deok-Sun Lee
The composition of cellular metabolism is different across species. Empirical data reveal that bacterial species contain similar numbers of metabolic reactions but that the cross-s…
Stability and selective extinction in complex mutualistic networks
Hyun Woo Lee, Jae Woo Lee, Deok-Sun Lee
We study species abundance in the empirical plant-pollinator mutualistic networks exhibiting broad degree distributions, with uniform intra-group competition assumed, by the Lotka-…
Skewness of local logarithmic exports
Sung-Gook Choi, Deok-Sun Lee
The distributions of trade values and relationships among countries and product categories reflect how countries select their trade partners and design export portfolios. Here we c…
Uncovering hidden dependency in weighted networks via information entropy
Mi Jin Lee, Eun Lee, Byunghwee Lee +3
Interactions between elements, which are usually represented by networks, have to delineate potentially unequal relationships in terms of their relative importance or direction. Th…
Optimizing hospital distribution across districts for reducing tuberculosis fatalities
Mi Jin Lee, Kanghun Kim, Junik Son +1
The spatial distributions of diverse facilities are often understood in terms of the optimization of the commute distance or the economic profit. Incorporating more general objecti…
