Growth of InAs/InP core-shell nanowires with various pure crystal structures.

We have studied the epitaxial growth of an InP shell on various pure InAs core nanowire crystal structures by metal-organic vapor phase epitaxy. The InP shell is grown on wurtzite (WZ), zinc-blende (ZB), and {111}- and {110}-type faceted ZB twin-plane superlattice (TSL) structures by tuning the InP shell growth parameters and controlling the shell thickness. The growth results, particularly on the

Efficacy and tolerability of proactive treatment with topical corticosteroids and calcineurin inhibitors for atopic eczema: systematic review and meta-analysis of randomized controlled trials

P>Background Long-term low-level topical anti-inflammatory therapy has been suggested as a new paradigm in the treatment of atopic eczema (AE). Objectives To determine the efficacy and tolerability of topical corticosteroids and calcineurin inhibitors for flare prevention in AE. Methods Systematic review of randomized controlled trials reporting efficacy of topical corticosteroids and/or topical c

Polyelectrolyte Mediated Interactions in Colloidal Dispersions: Hierarchical Screening, Simulations, and a New Classical Density Functional Theory

The pair interaction between two charged colloidal particles, in the presence of a polyelectrolyte as well as simple salt, is analyzed theoretically. Of particular interest is the way in which such a combination of salts can be used to induce a strong, long-range attraction, with at most a minor free energy barrier. We show that the nature of the simple salt is highly relevant, i.e., 2:1, 1:1, and

Differential patterns of spontaneous experiential response to a hypnotic induction: A latent profile analysis.

A hypnotic induction produces different patterns of spontaneous experiences across individuals. The magnitude and characteristics of these responses covary moderately with hypnotic suggestibility, but also differ within levels of hypnotic suggestibility. This study sought to identify discrete phenomenological profiles in response to a hypnotic induction and assess whether experiential variability

We will be different! Ageism and the temporal construction of old age

Abstract in UndeterminedAgeism has been described as different from other forms of discrimination and paradoxical in the sense that "nonold" people discriminate against their "future selves." The argument of this article is that nonold people may uphold ideas about older people as "the other" by constructing their own future selves as "essentially different" from that of older people of the presen

RapA2 Is a Calcium-binding Lectin Composed of Two Highly Conserved Cadherin-like Domains That Specifically Recognize Rhizobium leguminosarum Acidic Exopolysaccharides

In silico analyses have revealed a conserved protein domain (CHDL) widely present in bacteria that has significant structural similarity to eukaryotic cadherins. A CHDL domain was shown to be present in RapA, a protein that is involved in autoaggregation of Rhizobium cells, biofilm formation, and adhesion to plant roots as shown by us and others. Structural similarity to cadherins suggested calciu

Improvement in time-domain induced polarization data quality with multi-electrode systems by separating current and potential cables

Measuring induced polarization in the time domain with relatively compact multi-channel multi-electrode systems is attractive because of the simplicity of the procedure and thus its efficiency in the field. However the use of this technique is sometimes discouraged by the bad quality of the measurements in cases of high electrode contact resistances that can render data interpretation infeasible o

Connectivity in Reed Warblers Acrocephalus scirpaceus between breeding grounds in Europe and autumn stopover sites in Iberia

We determined the degree of connectivity in the Eurasian Reed Warbler Acrocephalus scirpaceus between breeding regions in central and northern Europe and stopover sites in Iberia, during the autumn migration. We used both recovery data and wing length analyses to achieve this. Biometric data were obtained during 2009 at 11 sampling localities in Iberia, which we amalgamated into four major migrato

Polymorphism of Paracetamol: A New Understanding of Molecular Flexibility through Local Methyl Dynamics.

This study focuses on the interplay of molecular flexibility and hydrogen bonding manifested in the monoclinic (form I) and orthorhombic (form II) polymorphs of paracetamol. By means of incoherent inelastic neutron scattering and density functional theory calculations, the relaxation processes related to the methyl side-group reorientation were analyzed in detail. Our computational study demonstra

De-Essentializing the Knowledge Intensive Firm: Reflections on Sceptical Research Going against the Mainstream

This paper provides an updated summary and discussion of my 1993 JMS paper 'Organization as rhetoric: knowledge-intensive firms and the struggle with rhetoric', and relate this to my own and others' later work in the area explored in the paper: knowledge-intensive work and discourse. A key aspect of knowledge work is the ambiguity of what it stands for, what people working with 'knowledge' are doi

STrengthening the Reporting of OBservational studies in Epidemiology - Molecular Epidemiology (STROBE-ME): An extension of the STROBE statement.

SUMMARY POINTS: Advances in laboratory techniques have led to a rapidly increasing use of biomarkers in epidemiological studies. Biomarkers of internal dose, early biological change, susceptibility and clinical outcomes are used as proxies for investigating interactions between external and/or endogenous agents and body components or processes. The need for improved reporting of scientific researc

Amniotic Fluid Phthalate Levels and Male Fetal Gonad Function.

Prenatal exposure to phthalates may pose a threat to human male reproduction. However, additional knowledge about the in vivo effect in humans is needed, and reported associations with genital abnormalities are inconclusive. We aimed to study prenatal di(2-ethylhexyl) phthalate (DEHP) and diisononyl phthalate (DiNP) exposure in relation to cryptorchidism, hypospadias, and human fetal Leydig cell f

Telomerase-dependent generation of 70-nt-long telomeric single-stranded 3' overhangs in yeast

Telomeres, the chromatin structures at the ends of eukaryotic chromosomes, are essential for chromosome stability. The telomere terminates with a TG-rich 3' overhang, which is bound by sequence-specific proteins that both protect the end and regulate the telomerase elongation process. Here, we demonstrate the presence of 3' overhangs as long as 200 nt in asynchronously growing cells of the budding

Magnetoresistance in Mn ion-implanted GaAs:Zn nanowires

We have investigated the magnetoresistance (MR) in a series of Zn doped (p-type) GaAs nanowires implanted with different Mn concentrations. The nanowires with the lowest Mn concentration (similar to 0.0001%) exhibit a low resistance of a few k Omega at 300 K and a 4% positive MR at 1.6 K, which can be well described by invoking a spin-split subband model. In contrast, nanowires with the highest Mn

Crystalline anatase-rich titanium can reduce adherence of oral streptococci.

Dental implant abutments that emerge through the mucosa are rapidly covered with a salivary protein pellicle to which bacteria bind, initiating biofilm formation. In this study, adherence of early colonizing streptococci, Streptococcus gordonii, Streptococcus oralis, Streptococcus mitis and Streptococcus sanguinis to two saliva-coated anodically oxidized surfaces was compared with that on commerci

Genomic Heterogeneity in Acute Leukemia.

Acquired genetic aberrations are the underlying cause of leukemogenesis in acute myeloid leukemia (AML) and acute lymphoblastic leukemia (ALL). The karyotypes of AML and ALL cases are generally quite simple as seen by chromosome banding analysis, with few genetic changes and a limited number of subclones. However, investigations using fluorescence in situ hybridization, loss of heterozygosity anal
