The replication of the Miguel and Kremer 2004 Econometrica paper, “Worms: Identifying Impacts on Education and Health In the Presence of Treatment Externalities”, carried out by Aiken et al. and Davey et al. and our responses to the replication, which can be found here and here, triggered discussions by scholars and media taking an interest in the evidence base for mass deworming policies in re...

The exact solutions to the Davey-Stewartson 1 equations are constructed to describe the development of a transversal solitary wave instability. Two types of plane dark soliton decays into two-dimensional solitary waves are found and analysed. It is also shown that the transversal instability of one-dimensional waveguides leads only to a shift of their drift velocity under the action of nonlocal...

A new (scalar) spectral decomposition is found for the Dirac system in two dimensions associated to the focusing Davey–Stewartson II (DSII) equation. Discrete spectrum in the spectral problem corresponds to eigenvalues embedded into a two-dimensional essential spectrum. We show that these embedded eigenvalues are structurally unstable under small variations of the initial data. This instability...
