Changes in regional inequality in rural China: decomposing the Gini index by income sources

A new method is proposed to decompose inequality changes as measured by the Gini index into structural effects, real inequality effects and interactive effects. Application of the method to updated Chinese data reveals that structural effects represent the driving force underlying the increasing trend in regional income inequality in rural China. Policy implications are explored. In addition to these contributions, considerable efforts are made to construct the income data used in the article. Pitfalls in measuring income inequality in rural China are discussed.Community/Rural/Urban Development,

Magnonic momentum transfer force on domain walls confined in space

Momentum transfer from incoming magnons to a Bloch domain wall is calculated using one dimensional continuum micromagnetic analysis. Due to the confinement of the wall in space, the dispersion relation of magnons is different from that of a single domain. This mismatch of dispersion relations can result in reflection of magnons upon incidence on the domain wall, whose direct consequence is a transfer of momentum between magnons and the domain wall. The corresponding counteraction force exerted on the wall can be used for the control of domain wall motion through magnonic linear momentum transfer, in analogy with the spin transfer torque induced by magnonic angular momentum transfer.Comment: 5 pages, 3 figure, published versio
