We report on the influence of hydrogen bromide (HBr) in situ etching on the growth of InP, GaP and GaAs nanowires. We find that HBr can be used to impede undesired radial growth during axial growth for all three material systems. The use of HBr opens a window for optimizing the growth parameters with respect to the materials' quality rather than only their morphology. Transmission electron microsc
Normal glucose homeostasis is characterized by appropriate insulin secretion and low HbA1c. Gene expression signatures associated with these two phenotypes could be essential for islet function and patho-physiology of type 2 diabetes (T2D). Herein, we employed a novel approach to identify candidate genes involved in T2D by correlating islet microarray gene expression data (78 donors) with insulin
A robust understanding of Antarctic Ice Sheet deglacial history since the Last Glacial Maximum is important in order to constrain ice sheet and glacial-isostatic adjustment models, and to explore the forcing mechanisms responsible for ice sheet retreat. Such understanding can be derived from a broad range of geological and glaciological datasets and recent decades have seen an upsurge in such data
The aim of this article is to examine conceptually and empirically how innovative firms combine knowledge (1) provided by different sources, (2) accessed at different spatial scales and (3) acquired through different channels. We add to the conceptual debate by contrasting and synthesising the perspectives offered on these issues by four key concepts, namely the local buzz and global pipelines arg
The incorporation of analytical kernel information is exploited in the construction of Nyström discretization schemes for integral equations modeling planar Helmholtz boundary value problems. Splittings of kernels and matrices, coarse and fine grids, high-order polynomial interpolation, product integration performed on the fly, and iterative solution are some of the numerical techniques used to se
This work reassesses the global atmospheric budget of H2 with the TM5 model. The recent adjustment of the calibration scale for H2 translates into a change in the tropospheric burden. Furthermore, the ECMWF Reanalysis-Interim (ERA-Interim) data from the European Centre for Medium-Range Weather Forecasts (ECMWF) used in this study show slower vertical transport than the operational data used before
Background: To investigate the long-term effects of cholinesterase inhibitor (ChEI) therapy and the influence of sociodemographic and clinical factors on the use of community-based home help services (HHS) by patients with Alzheimer's disease (AD). Methods: This 3-year, prospective, multicenter study included 880 AD patients treated with donepezil, rivastigmine, or galantamine in a routine clinica
Abstract in UndeterminedThe aim was to use Todd Ebert's Hats puzzle to devise a Dutch Book showing that individual rationality could add up to collective irrationality even if the players aim to promote common goals. Situations in which this happens involve violations of what might be called the Group-Reflection Principle. The Dutch book that can be set up against groups that violate Group-Reflect
Uncomplicated urinary tract infections (UTIs) in otherwise healthy premenopausal women are one of the most frequent infections in the community. Therefore any improvement in management will have a high impact not only on the quality of life of the individual patient but also on the health system. In placebo-controlled studies antimicrobial treatment was significantly more effective than placebo, b
This paper presents the application of a variety of techniques to study jet substructure. The performance of various modified jet algorithms, or jet grooming techniques, for several jet types and event topologies is investigated for jets with transverse momentum larger than 300 GeV. Properties of jets subjected to the mass-drop filtering, trimming, and pruning algorithms are found to have a reduce
In experimental design and 3D reconstruction it is desirable to minimize the number of observations required to reach a prescribed estimation accuracy. Many approaches in the literature attempt to find the next best view from which to measure, and iterate this procedure. This paper discusses a continuous optimization method for finding a whole set of future imaging locations which minimize the rec
Background: Two new pneumococcal conjugate vaccines were licensed to immunize infants and young children against pneumococcal disease. Objectives: The objective of this study was to estimate the expected health benefits, costs, and incremental cost-effectiveness of routine vaccination with the 10-valent pneumococcal nontypeable hemophilus influenza protein-D conjugate vaccine (PHiD-CV) compared wi
We have studied how backbone N-H S-2 order parameters calculated from molecular dynamics simulations depend on the method used to calculate them, the starting conditions, and the length of the simulations. Using the carbohydrate binding domain of galectin-3 in the free and lactose-bound states as a test case, we compared the calculated order parameters with experimental data from NMR relaxation. T
Type 2 diabetes is associated with a higher cardiovascular risk and there has been a growing interest in using dietary intervention to improve lipid profile and glucose control. The present work aims at analysing the effects of the enrichment of a normal diet with beta-glucan (3-5 g/d) in free-living type 2 diabetic subjects for 2 months, using a palatable soup. This trial was a parallel, placebo-
TURBT is the initial diagnostic procedure in bladder cancer (BC). Hypothetically, tumor resection could induce seeding of cancer cells into the circulation and subsequent metastatic disease. The objective of this study was to ascertain whether TURBT induces measurable seeding of cancer cells into the vascular system.
OBJECTIVES: The findings of experimental studies suggest that the immune system plays a key role in atherosclerosis but the clinical importance of different immune cells in cardiovascular disease remains poorly characterized. In this study we investigated the association between CD8(+) T cells and carotid disease as well as development of cardiovascular disease events. DESIGN: The study cohort com
The power of nanofluidic channels to analyze DNA is described along with practical experimental hints. As an introduction, a general overview is given on conventional DNA analysis tools, as well as tools under development towards the $1000 genome. The focus of this tutorial review is the stretching of DNA in nanoscale channels for coarse-grained mapping of DNA. To understand the behavior of the DN
Although it appears biologically plausible for iron to be associated with gastric carcinogenesis, the evidence is insufficient to lead to any conclusions. To further investigate the relationship between body iron status and gastric cancer risk, we conducted a nested case-control study in the multicentric European Prospective Investigation into Cancer and Nutrition (EPIC) study. The study included
Objective: To estimate the incidence of hospitalization for paediatric obstructive sleep apnoea syndrome (OSAS) or sleep-disordered breathing (SDB) caused by adenotonsillar or tonsillar hypertrophy without infection in children with a parent affected by OSAS. Patients and methods: Using the MigMed database at Lund University, hospital data on all children aged 0-18 years in Sweden between 1997 and
