This paper develops a new approach in the analysis of the Camassa-Holm equation. By introducing a new set of independent and dependent variables, the equation is transformed into a semilinear system, whose solutions are obtained as fixed points of a contractive transformation. These new variables resolve all singularities due to possible wave breaking. Returning to the original variables, we obtai

To investigate whether preoperative retinal function measured by full-field ERG and multifocal ERG is correlated to postoperative visual acuity after macular hole surgery.

Using harmonic maps we provide an approach towards obtaining explicit solutions to the incompressible two-dimensional Euler equations. More precisely, the problem of finding all solutions which in Lagrangian variables (describing the particle paths of the flow) present a labelling by harmonic functions is reduced to solving an explicit nonlinear differential system in C-n with n = 3 or n = 4. Whil

This article offers an overview of some main approaches in Swedish Cold War studies with a specific attention to how this field of research has dealt with the media as historical sources. The historiographical development is divided into two major research paradigms, one focusing on politics and Sweden in the postwar global environment, and the other focusing on the cultural aspects of the Cold Wa

Objective: To estimate the effect of locally tailored clinical guidelines on intrapartum care and perinatal outcomes among women with severe hypertensive disorders in pregnancy (sHDP). Methods: A pre–post study at Zanzibar's low-resource Mnazi Mmoja Hospital was conducted. All labouring women with sHDP were included at baseline (October 2014 to January 2015) and at 9–12 months after implementation

We analysed the role of the prechordal plate in forebrain development of chick embryos in vivo. After transplantation to uncommitted ectoderm a prechordal plate induces an ectopic, dorsoventrally patterned, forebrain-like vesicle. Grafting laterally under the anterior neural plate causes ventralization of the lateral side of the forebrain, as indicated by a second expression domain of the homeobox

This chapter analyses the European Union’s efforts to counteract the erosion of member states’ corporate tax bases. The author first describes how multinational enterprises, like Apple, have been able to exploit differences between the tax systems in order to pay less taxes. The author then presents the hypothesis that EU member states have managed to defend their interests in protecting their own
