Accurate FET Model parameters need to be determined to give accurate simulation results for RF amplifiers. The accuracy required varies depending on the application of the final amplifier. For Doherty amplifiers, a high accuracy is required for the transfer characteristic of the amplifier. An amplifier was simulated using a model obtained from data sheet information, and then built. Measurement...

MRI is commonly used to determine the location and extent of cerebral gliomas. We investigated whether the diagnostic accuracy of MRI could be improved by the additional use of PET with the amino acid O-(2-[18F]fluoroethyl)-l-tyrosine (FET). In a prospective study, PET with FET and MRI was performed in 31 patients with suspected cerebral gliomas. PET and MRIs were co-registered and 52 neuronavi...

BACKGROUND Conflicting data exist for anti-cancer effects of anti-placental growth factor (anti-PlGF) in combination with anti-VEGF. Still, this treatment combination has not been evaluated in intracranial glioblastoma (GBM) xenografts. In clinical studies, position emission tomography (PET) using the radiolabeled amino acid O-(2-18F-fluoroethyl)-L-tyrosine (18F-FET) and magnetic resonance imag...

BACKGROUND Biological brain tumor imaging using O-(2-[18F]fluoroethyl)-L-tyrosine (FET)-PET combined with inverse treatment planning for locally restricted dose escalation in patients with glioblastoma multiforme seems to be a promising approach.The aim of this study was to compare inverse with forward treatment planning for an integrated boost dose application in patients suffering from a glio...

One dimensional graphene nanostructures are one of the most promising materials for next generation electronics. Here, chemical vapor depostion growth nanoribbons (GNRs) and nanospears (GNSs) on a copper surface is reported. The GNRs GNSs enabled by vapor–liquid–solid (VLS) mechanism guided on-surface propagation liquid Cu-Si catalyst particle. slow lateral fast VLS vertical give rise to spear ...

This paper describes the set of concepts that underlie the “Plug-Synapse” model, which supports endusers in composing and configuring ubiquitous computing applications. The technology that implements the model is briefly presented; all have been developed in the course of research during the e-Gadgets (IST-FET) project.

This paper introduces a modified particle swarm algorithm to handle multiobjective optimization problems. In multiobjective PSO algorithms, the determination of Pareto optimal solutions depends directly on the strategy of assigning a best local guide to each particle. In this work, the PSO algorithm is modified to assign a best local guide to each particle by using minimum angular distance info...

In this study, a model of a Schottky-barrier carbon nanotube fieldeffect transistor (CNT-FET), with ferromagnetic contacts, has been developed. The emphasis is put on analysis of current-voltage characteristics as well as shot (and thermal) noise. The method is based on the tight-binding model and the nonequilibrium Green’s function technique. The calculations show that, at room temperature, th...

This study introduces a Functional Electrical Therapy (FET) system based on sensor-driven electrical stimulation for the augmentation of walking. The automatic control relates to the timing of stimulation of four muscles. The sensor system comprises accelerometers and force-sensing resistors. The automatic control implements IF-THEN rules designed by mapping of sensors and muscle activation pat...

BACKGROUND Frozen embryo transfer (FET) is one of the most important supplementary procedures in the treatment of infertile couples. While general information concerning the outcome of fresh embryo transfer has been documented, paucity of investigations has addressed the clinical factors influenced on pregnancy rates in FET. OBJECTIVE In this study, we performed a retrospective analysis of cl...
