Here we present a study of the electronic structure of epitaxial ferromagnetic Mn5Ge3(0001) films on Ge(111) by means of x-ray absorption spectroscopy, x-ray photoelectron spectroscopy, and spin-resolved photoelectron spectroscopy. Spin-polarization (P) value of +(15 +/- 5)% at the Fermi energy (E-F) is measured with a photon energy of h nu = 21.2 eV. Our findings are in contrast to recent band st

Due to inhomogeneous broadening, the absorption lines of rare-earth-ion dopants in crystals are many order of magnitudes wider than the homogeneous linewidths. Several ways have been proposed to use ions with different inhomogeneous shifts as qubit registers, and to perform gate operations between such registers by means of the static dipole coupling between the ions. In this paper we show that in

Background: The aim of this study was to determine whether relative qualitative and quantitative differences in protein expression could be related to smoke exposure or smoke-induced airway inflammation. We therefore explored and characterized the protein components found in bronchoalveolar lavage (BAL) fluid sampled from either lifelong smokers or never-smokers. Methods: BAL fluid samples obtaine

During the last few decades, quality assurance has been a central issue in the societies, both in, for example the industrial area and in healthcare. It is a tool to measure the outcomes of product or service provided. A review of the literature during the last 17 years with respect to quality assurance work in psychiatric occupational therapy indicates that few articles have been published in the

An overview is given of Chiral Perturbation Theory and various applications to eta decays. In particular. the main decay eta --> 3pi is discussed at the one-loop level, and estimates of the higher order corrections are given. The importance of p(6) and higher order effects in double Dalitz and eta --> pi(0)gammagamma decays is pointed out. In all these cases the need for new experimental results i

The mechanical behaviour of soft biological tissues is governed by phenomena occurring on different scales of observation. From the computational modelling point of view, a vital aspect consists of the appropriate incorporation of micromechanical effects into macroscopic constitutive equations. In this work, particular emphasis is placed on the simulation of soft fibrous tissues with the orientati

The ability to regulate transgene expression will be crucial for development of gene therapy to the brain. The most commonly used systems are based on a transactivator in combination with a drug, e.g. the tetracycline-regulated system. Here we describe a different method of transgene regulation by the use of the human glial fibrillary acidic protein (GFAP) promoter. We constructed a lentiviral vec

This review presents the added value for diagnosis of acute ischemia/infarction of considering ST elevation in the 12 inverted leads (-I, -II, -II, -aVR, etc) of the standard electrocardiogram in addition to ST elevation in 12 positive leads. A small number of studies have been published showing substantial increases in sensitivity at the "cost of' slight decreases in specificity. One recent study

In this paper we present an object detection system for city environments. We focus on the problem of automatically detecting windows on buildings. Several possible applications for the detection system are given, such as recognition of buildings, pose estimation, rectification and 3D reconstruction. Experimental validations on real images are also provided. The system is capable of detecting wind

Randomized clinical trials have established the role of third-generation aromatase inhibitors (AIs) (letrozole, anastrozole, and exemestane) as standard treatment for patients with hormone-sensitive metastatic breast cancer who have experienced disease progression with antiestrogen therapy. Significant gains in clinical efficacy and improved tolerability over progestins (megestrol acetate) and the

Background/Aims: This study aims at describing the natural history and outcome of small duct primary sclerosing cholangitis (PSC). Methods: Thirty-two patients with small duct PSC were studied. The average time taken for diagnosis was 69 (1-168) months. The median follow-up time was 63 (1-194) months. Results: All patients including one who underwent liver transplantation because of end-stage live

The paper treats the problem of ratio control. Previous solutionsbased on simple Ratio stations perform poorly during transientscaused by setpoint changes. A new solution, the Blend station, thatimproves control during transients, is proposed. Both a constant-gainand an adaptive version are presented.

In this article, we evaluate the work out of some artificial neural network models as tools for support in the medical diagnosis of urological dysfunctions. We develop two types of unsupervised and one supervised neural network. This scheme is meant to help the urologists in obtaining a diagnosis for complex multi-variable diseases and to reduce painful and costly medical treatments since neurolog

Insects active in dim light, such as moths and many beetles, normally have superposition compound eyes to increase photon capture. But there are nocturnal and crepuscular insects - such as some species of bees, wasps and butterflies - that have apposition compound eyes. These are likely to have adaptations - including large eye and facet size and coarsened spatial and temporal resolution - that im

The irritation response of the rabbit eye to trigeminal nerve stimulation, which includes a breakdown of the blood-aqueous barrier (BAB), seems to be due to the release of substance P (SP) and calcitonin gene-related peptide (CGRP). In order to assess the relative importance of these two peptides for the barrier effect, and the role of arachidonic acid metabolites (AAM) in the response, we have st
