Transient electromagnetic waves and inversion techniques

This paper reviews an efficient inversion technique for complex media utilizing transient electromagnetic scattering data. The approach to solve the scattering problems (direct and inverse) relies on a wave splitting technique and an invariant imbedding technique. The analysis is illustrated by a numerical example.

Neuropeptides in cerebrospinal fluid of patients with Alzheimer's disease and dementia with frontotemporal lobe degeneration

The two major primary degenerative dementias, dementia of Alzheimer type (DAT) and frontal lobe degeneration of non-Alzheimer type (FLD) have several clinical features in common but also many symptoms that differ. In a clinical material of 80 patients with either of the two forms of dementia (DAT = 39, FLD = 41) we have studied the levels of neuropeptides in the cerebrospinal fluid (CSF) in order

Mobility Support in Private Networks Using RPX

The limited IPv4 address space has driven the cellular industry to start using IPv6 addresses for mobile users in 3G-networks. However, there is a potential threat to the success of 3G-network deployment, as the success will depend on the services offering to the end users. Currently, the overwhelming proportion of services resides in the IPv4 address space, which makes them inaccessible to users
