Emerging wireline transmission systems such as G.fast use bands up to around 200 MHz on short cables. A key enabler for achieving the aspired throughput of several hundred Mbit/s is joint processing of transmit signals in downstream direction as well as joint processing of receive signals in upstream direction through techniques referred to as vectoring. A new challenge in such systems are sudden

Språklagen, som trädde i kraft 2009, avser att skydda användandet av svenskan som ett komplett och samhällsbärande språk i Sverige. Den slår fast att ”[s]venska är huvudspråk i Sverige” (SFS 2009:600) samtidigt som den värnar om den språkliga mångfalden i Sverige och den enskilde individens rätt till språk, och kan därmed klassas som en mångspråkig policy. Sådana policyer kan skapa utrymme för fle

Narrative as a Socially Symbolic Act (1981), is applied. An argument is developed to the effect that Kurosawa's much reputed humanism is shown to have its main source, not in the Western philosophi

The time domain version of the optical theorem is discussed. The theorem is derived from the optical theorem in the frequency domain by the Parseval’s relation. It expresses the sum of the scattered and absorbed energies in terms of the scattered farfield in the forward direction. From the theorem, causality, and reciprocity a number of results concerning the scattered and absorbed energies from a

The survival and growth of intrahippocampal septal suspension grafts were investigated by acetylcholine esterase (AChE) histochemistry in animals with lesions of the intrinsic septohippocampal cholinergic pathways. AChE was demonstrable in the grafts after the first postoperative week, and AChE-positive fibres were seen to extend into the host hippocampus by 3 weeks. Rapid fibre outgrowth occurred
