PIV measurements are performed in a channel with periodic ribs on one wall. The emphasis of this study is to investigate the flow structures in the vicinity of a rib in terms of mean velocities, Reynolds stresses, probability density functions (PDF), and two-point correlations. The PDF distribution of u0 is bimodal in the separated shear layer downstream of the rib. The maximum Reynolds shear stre
We analyze the destructive effects of mutual coupling and spatial correlation between the separate antenna elements on a combined diversity system consisting of multiple HAPs (High-Altitude Platforms) employing various compact MIMO (Multiple-Input Multiple-Output) antenna array configurations, in order to enhance the mutual information in HAP communication links. In addition, we assess the influen
Free nanoscale tin clusters in the average size range of a few tens up to similar to 500 atoms are studied by means of valence and core-level photoelectron spectroscopy. A self-consistent picture arises from comparison of the work functions derived from the 4d core-level spectra, the experimental ionization energies extracted from the 5p valence spectra, and the expectations from the metallic sphe
Cellular reprogramming is a new and rapidly emerging field in which somatic cells can be turned into pluripotent stem cells or other somatic cell types simply by the expression of specific combinations of genes. By viral expression of neural fate determinants, it is possible to directly reprogram mouse and human fibroblasts into functional neurons, also known as induced neurons. The resulting cell
Objective: The European Association of Communication in Healthcare (EACH) Early Career Researchers Network (ECRN) aims are to (1) promote international collaboration among young investigators and (2) provide a support network for future innovative communication research projects. In October 2009, Miami, USA at a workshop facilitated by the ECRN at the International Conference on Communication in H
Global environmental changes and human activity influence wildland fires worldwide, but the relative importance of the individual factors varies regionally and their interplay can be difficult to disentangle. Here we evaluate projected future changes in burned area at the European and sub-European scale, and we investigate uncertainties in the relative importance of the determining factors. We sim
For ceramics to be relevant in the Southern African Iron Age, archaeologists must broaden their theoretical base to include social and other contexts when interpreting material culture items such as pottery. Pottery remains critical in understanding cultural dynamics in the region for the past two millennia, but current usage is narrow in scope. Using ethnohistorical data and archaeological exampl
This article explores three entrepreneurial ventures that have evolved in proximity to online piracy. In reviewing the respective cases of Spotify, Skype, and The Pirate Bay, the argument outlines the radically divergent strategies with which the entrepreneurs have sought to legitimise their ventures and underlying technologies. The article concludes that 1) the context of practices labelled “pira
The concept of using pharmacokinetics for prophylactic dose tailoring with limited blood sampling in clinical practice has been demonstrated for factor VIII but not for factor IX. The pharmacokinetics of factor IX are more complicated than for factor VIII and also differ between plasma-derived and recombinant factor IX. Therefore, the pharmacokinetics of factor IX need to be further explored in cl
Based on the randomised Euro-EWING99-R1 trial, vincristine, adriamycin, cyclophosphamide (VAC) may be able to replace vincristine, adriamycin, ifosfamide (VAI) in the treatment of standard-risk Ewing sarcoma. However some heterogeneity of treatment effect by gender was observed. The current exploratory study aimed at investigating the influence of gender on treatment efficacy and acute toxicity.
The d-orbital contribution from the transition metal centers of phthalocyanine brings difficulties to understand the role of the organic ligands and their molecular frontier orbitals when it adsorbs on oxide surfaces. Here we use zinc phthalocyanine (ZnPc)/TiO2(110) as a model system where the zinc d-orbitals are located deep below the organic orbitals leaving room for a detailed study of the inte
Evaluating the correctness of eyewitness statements is one of the biggest challenges for the legal system, and this task is currently typically performed by human evaluations. Here we study whether a computational method could be applied to discriminate between correct and incorrect statements. The Semantic Evaluation Method (SEM) is based on Latent Semantic Analysis (LSA, Landauer & Dumais, 1
III-V antimonide nanowires are among the most interesting semiconductors for transport physics, nanoelectronics and long-wavelength optoelectronic devices due to their optimal material properties. In order to investigate their complex crystal structure evolution, faceting and composition, we report a combined scanning electron microscopy (SEM), transmission electron microscopy (TEM), and scanning
Introduction: Mer and Tyro3 are receptor tyrosine kinases important for the phagocytosis of apoptotic cells. Together with Axl, they constitute the TAM receptor family. These receptors can be shed from the cell membrane and their soluble extracellular regions can be found in plasma. The objective of this study was to elucidate whether the plasma levels of soluble Mer (sMer) and Tyro3 (sTyro3) were
Studies of determinants of development of inhibitory antibodies to factor VIII in people with hemophilia A indicate a complex process involving multiple factors. The Hemophilia Inhibitor Genetics Study Combined Cohort was formed to extend understanding of the genetic background of risk. The study group contains 833 subjects from three independent cohorts: brother pairs and singletons with and with
Non-typeable Haemophilus influenzae (NTHi) is a human-specific mucosal pathogen and one of the most common causes of bacterial infections in children and patients with chronic obstructive pulmonary disease. It is also frequently found in polymicrobial superinfections. Great strides have recently been made in the understanding of the molecular mechanisms underlying NTHi pathogenesis.
Immune escape mechanisms promote tumor progression and are hurdles of cancer immunotherapy. Removing immunosuppressive cells before treatment can enhance efficacy. Tyrosine kinase inhibitors (TKI) may be of interest to combine with immunotherapy, as it has been shown that the inhibitor sunitinib reduces myeloid suppressor cells in patients with renal cell carcinoma and dasatinib promotes expansion
It is well-known that the Anglo-Boer War attracted support and sympathy for the Boer cause from all over Europe. One topic that has not received much scholarly attention, however, is the contribution of Scandinavian medical doctors and nurses in the conflict. One of them was the Swedish surgeon Josef Hammar. This article argues that his participation was for both idealistic and pragmatic reasons.
We report that many histone modifications are unevenly distributed over the HPV16 genome in cervical cancer cells as well as in HPV16-immortalized keratinocytes. For example, H3K36me3 and H3K9Ac that are common in highly expressed cellular genes and over exons, were more common in the early than in the late region of the HPV16 genome. In contrast, H3K9me3, H4K20me3, H2BK5me1 and H4K16Ac were more
