Published: October 2013

SummaryRationaleSport participation is especially important for patients with asthma in that it decreases psychosocial and physiological problems associated with inactivity. However, adolescents with asthma seem to participate less in sports compared to their non‐asthmatic peers. The current study tested the direct associations between maternal sport‐specific factors and sport club participation of early adolescents with asthma and the indirect effect through adolescent's sport‐specific cognitions.MethodsDuring home visits, 261 adolescents (aged 10–15) completed questionnaires about self‐efficacy, beliefs regarding sport participation, and their actual sport club participation. Their mothers reported their sport‐specific support, beliefs about offspring's and own sport participation, their own levels of physical activity, and their self‐efficacy to stimulate offspring to participate in sports. Path analyses were used to examine the direct and indirect associations of maternal sport‐specific factors with adolescents sport club participation via adolescent sport‐specific cognitions.ResultsAnalyses showed that maternal sport‐specific support (β = 0.20, P = 0.007) and self‐efficacy to stimulate offspring to participate in sports (β = 0.20, P = 0.027) related positively to adolescents' sport club participation. Adolescents' self‐efficacy (indirect effect = 0.09, SE = 3.01, P < 0.001) mediated the positive relation between maternal self‐efficacy to stimulate offspring to participate in sport and adolescents' participation in sport clubs.ConclusionMaternal sport‐specific factors related to adolescents' sport club participation directly and indirectly through adolescents' sport‐specific cognitions. Intervention programs should focus on maternal sport‐specific support and self‐efficacy and adolescents' self‐efficacy to increase sport participation of adolescents with asthma.

AbstractBACKGROUNDProstate tumor‐initiating cells (TICs) have intrinsic resistance to current therapies. TICs are commonly isolated by cell sorting or dye exclusion, however, isolating TICs from limited primary prostate cancer (PCa) tissues is inherently inefficient. We adapted the collagen adherence feature to develop a combined immunophenotypic and time‐of‐adherence assay to identify human prostate TICs.METHODSPCa cells from multiple cell lines and primary tissues were allowed to adhere to several matrix molecules, and fractions of adherent cells were examined for their TIC properties.RESULTSCollagen I rapidly‐adherent PCa cells have significantly higher clonogenic, migration, and invasion abilities, and initiated more tumor xenografts in mice when compared to slowly‐adherent and no‐adherent cells. To determine the relative frequency of TICs among PCa cell lines and primary PCa cells, we utilized zebrafish xenografts to define the tumor initiation potential of serial dilutions of rapidly‐adherent α2β1hi/CD44hi cells compared to non‐adherent cells with α2β1low/CD44low phenotype. Tumor initiation from rapidly‐adherent α2β1hi/CD44hi TICs harboring the TMPRSS2:ERG fusion generated xenografts comprising of PCa cells expressing Erg, AMACR, and PSA. Moreover, PCa‐cell dissemination was consistently observed in the immune‐permissive zebrafish microenvironment from as‐few‐as 3 rapidly‐adherent α2β1hi/CD44hi cells. In zebrafish xenografts, self‐renewing prostate TICs comprise 0.02–0.9% of PC3 cells, 0.3–1.3% of DU145 cells, and 0.22–14.3% of primary prostate adenocarcinomas.CONCLUSIONZebrafish PCa xenografts were used to determine that the frequency of prostate TICs varies among PCa cell lines and primary PCa tissues. These data support a paradigm of utilizing zebrafish xenografts to evaluate novel therapies targeting TICs in prostate cancer. Prostate 74:187–200, 2014. © 2013 Wiley Periodicals, Inc.

Published: October 2013

AbstractIndium gallium nitride (InGaN)/aluminium nitride (AlN) self‐assembled nanodisk light emitting diode (LED) structures were grown on sapphire substrate using metalorganic vapor phase epitaxy (MOVPE). Structural analysis shows that the initial AlN layer plays a crucial role in the formation of nanodisk structure. Nanodisks were formed due to cracks introduced in the first AlN layer on n‐GaN template. The succeeding InGaN/AlN layers introduced branching of the nanodisks due to cracks from the initial AlN layer. The structural properties of nanodisk were confirmed from atomic force microscopy (AFM) and high‐angle annular dark‐field (HAADF) images. Observation of electroluminescence (EL) showed that, at lower injection current orange (605 nm) color light was emitted and that when the injection current increased the wavelength shifted from orange to yellow (586 nm). This large EL blue shift observed in the nanodisk LED was due weakening of the quantum confined stark effect (QCSE) at high injection current. (© 2013 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
Thermal stability of single crystalline alpha gallium oxide films on sapphire substrates
Authors: Lee Sam‐Dong , Akaiwa Kazuaki , Fujita Shizuo 
Published: October 2013

AbstractHigh quality single crystalline alpha gallium oxide (α‐Ga2O3) films, as highlighted by the X‐ray diffraction ω‐scan full‐width at half maximum of as small as 30 arcsec, were prepared by the mist chemical vapor deposition (CVD). The quality of the film was markedly dependent of the carrier gas flow rate, so we need careful attention for the optimum growth conditions. The thermal stability of α‐Ga2O3 films was investigated by studying their thermal stability under thermal annealing in terms of the structural and optical properties. It was found that α‐Ga2O3films grown at 470 °C are stable until 550 °C, but are gradually transformed to β‐Ga2O3over 600 °C. Finally, β‐Ga2O3films only existed at 700 °C. So the device processes for α‐Ga2O3 should be done below 550 °C to avoid phase transformation. (© 2013 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
Comparative study on nano‐scale III‐V double‐gate MOSFETs with various channel materials

Published: October 2013

AbstractThe current drivability of III‐V double gate MOSFETs with various channel materials are investigated by using quantum‐corrected Monte Carlo simulation. The InGaAs channel shows the largest electron injection velocity vinj. However, the backward currents by alloy scattering (AL) in the channel and by non‐polar optical phonon scattering (NPOP) in the drain decrease the average electron velocity vs from vinj even at Lg of 10 nm. In the GaAs channel, in addition to the decrease in vinj by the L valleys conduction, NPOP and polar optical phonon scattering (POP) cause the backward currents, which decrease vs further from vinj. The InP channel shows the smallest vinj, however, the backward current by POP in the channel is small and that by NPOP in the drain is almost negligible. Therefore vs is almost reaching vinj at Lg of 10 nm. On the other hand, the electron density nb is largest in the InP channel owing to the large Cgs. Eventually, the InP channel shows the largest Ids. (© 2013 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

Published: October 2013

AbstractCrystallized 4,7‐diphyenyl‐1,10‐phenanthroline (BPhen) films deposited by convenient vacuum thermal evaporation technique have been found to be an efficient means to extract the substrate wave guided light in organic light emitting diodes (OLEDs). The optimized BPhen film working as organic scattering layer was successfully used with OLEDs for light outcoupling efficiency improvement. Enhancement of 26%, 15% and 6% in efficiency of the blue, green and red OLEDs were obtained, respectively. The achievement was found to be advantageous in terms of simplicity of fabrication method and feasibility for large area OLED applications. (© 2014 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
Improving the selection of IASI channels for use in numerical weather prediction
Authors: Ventress L. , Dudhia A. 
Published: October 2013

High‐resolution infrared sounders, such as the Infrared Atmospheric Sounding Interferometer (IASI) on the current MetOp series of satellites, produce several orders of magnitude more data per location than previous instruments used in operational retrieval and data assimilation schemes. Using the full spectrum (8641 channels for IASI) is impractical and a common approach is to identify a subset of channels which, ideally, conveys the most information on the target parameters (e.g. atmospheric temperature and water vapour) but using a relatively small number of measurements.Representing the problem as a one‐dimensional retrieval, optimal estimation provides an efficient framework for channel selection, and is the basis of several current schemes. However, while modelling the propagation of random (spectrally uncorrelated) errors into the retrieval, the standard algorithm does not allow for spectrally correlated errors, particularly arising from the radiative transfer modelling, which are often the limiting factor in retrieval accuracy. Such errors are either ignored or represented only approximately during the selection.This article describes a modification to the standard algorithm which allows spectrally correlated errors to be properly modelled, and quantified, within the channel selection process. Comparing the results with an established selection scheme shows that significant improvements can be obtained when retrieving temperature regarding water vapour as an error term, but are less dramatic when both are retrieved together. The concept of ‘total’ information available from an IASI spectrum is also re‐assessed.
Agile maturity model: analysing agile maturity characteristics from the SPICE perspective
Authors: Schweigert Tomas , Vohwinkel Detlef , Korsaa Morten , Nevalainen Risto , Biro Miklos 
Published: October 2013

AbstractThe paper discusses structure, quality and content of the currently available agile maturity models. It presents two approaches on how to deal with such models. As a first step of the analysis, the paper contains a compilation of maturity level naming used by these agile maturity models because the variety of level naming is a sign of the variety of understanding and of definition of agile maturity.While many papers deal with agile from an inside perspective, this paper is written from the perspective of Software Process Improvement (SPI) and Capability Determination, the European Certification and Qualification Association PI Manager Certification Scheme and also the SPI Manifesto.The paper does not explicitly present its own agile maturity model.The analysis approaches presented in the paper show that the currently available agile maturity models are not fit for industrial use. The synthesis of an acceptable model seems to be feasible as the analysed models address typical organisational processes including life cycle management. Copyright © 2013 John Wiley & Sons, Ltd.
FGF2 and Insulin Signaling Converge to Regulate Cyclin D Expression in Multipotent Neural Stem Cells

Published: October 2013

Abstract
The ex vivo expansion of stem cells is making major contribution to biomedical research. The multipotent nature of neural precursors acutely isolated from the developing central nervous system has been established in a series of studies. Understanding the mechanisms regulating cell expansion in tissue culture would support their expanded use either in cell therapies or to define disease mechanisms. Basic fibroblast growth factor (FGF2) and insulin, ligands for tyrosine kinase receptors, are sufficient to sustain neural stem cells (NSCs) in culture. Interestingly, real-time imaging shows that these cells become multipotent every time they are passaged. Here, we analyze the role of FGF2 and insulin in the brief period when multipotent cells are present. FGF2 signaling results in the phosphorylation of Erk1/2, and activation of c-Fos and c-Jun that lead to elevated cyclin D mRNA levels. Insulin signals through the PI3k/Akt pathway to regulate cyclins at the post-transcriptional level. This precise Boolean regulation extends our understanding of the proliferation of multipotent NSCs and provides a basis for further analysis of proliferation control in the cell states defined by real-time mapping of the cell lineages that form the central nervous system.

How climate change mitigation could harm development in poor countries
Authors: Jakob Michael , Steckel Jan Christoph 
Published: October 2013

Avoiding dangerous climate changes requires emission reductions in not only industrialized but also developing countries. This opinion piece argues that even if the ‘full incremental costs’ of abatement in developing countries would be covered by industrialized countries, the former's development prospects could be hampered by climate change mitigation due to the following reasons. First, financial inflows have the potential to induce a ‘climate finance curse’ similar to adverse effects related to natural resource exports. Second, increased use of more expensive low‐carbon energy sources could delay structural change and the build‐up of physical infrastructure. Third, higher energy prices could have negative effects on poverty and inequality. We conclude that these considerations should not be seen as an indication that one should abstain from emission reductions in developing countries. However, until developing countries' most severe concerns can be appropriately addressed, attention should be focused on measures that promote human well‐being while saving emissions.

AbstractTwo coordination polymers, {[Zn2(L)(bpy)]·2H2O}n (1) and [Zn2(L)(bpe)]n (2) [H4L = terphenyl‐2,2′,4,4′‐tetracarboxylic acid, bpy = 4,4′‐bipyridine, and bpe = 1,2‐bis(4‐pyridyl)ethane], were hydrothermally synthesized under similar conditions and characterized by elemental analysis, IR spectroscopy, TGA, and single‐crystal X‐ray diffraction analysis. Compound 1 has a 3D framework containing Zn–O–C–O–Zn 1D chains. Compound 2 exhibits a 3D framework, which features tubular channels. The channels are occupied by bpe molecules. The differences in the structures demonstrate that the auxiliary dipyridyl‐containing ligand has a significant effect on the construction of the final framework. Additionally, the fluorescent properties of the two compounds were also studied in the solid state at room temperature.

Authors: Ross Jan H. , Preuß Till , Brahms Christian , Doye Sven 
Published: October 2013

AbstractA simple, reliable, and reproducible procedure for the multi‐gram synthesis of highly pure bis(indenyl)dimethyltitanium is presented. The procedure relies on a one‐pot conversion of inexpensive indene, methyllithium, and titanium tetrachloride to [Ind2TiMe2] and a convenient and quick aqueous workup protocol. Overall, quantities of several grams of [Ind2TiMe2] can be synthesized within a few hours. The procedure can also be used for the synthesis of [Cp2TiMe2] from cyclopentadiene, methyllithium, and titanium tetrachloride.

Published: October 2013

AbstractThis study describes the incidence of workplace bullying among perioperative RNs, surgical technologists, and unlicensed perioperative personnel in two academic medical centers. The study sought to determine whether the demographic variables of gender, ethnicity, hospital, years of experience on the unit, years in the profession, and job title predict the experience of workplace bullying; whether a relationship exists between workplace bullying and emotional exhaustion; and whether bullying is associated with perceptions of patient safety in the OR. The cross‐sectional design included perioperative nurses, surgical technologists, and unlicensed perioperative personnel (N = 167). Fifty‐nine percent of the study participants reported witnessing coworker bullying weekly, and 34% reported at least two bullying acts weekly. Having one's opinion ignored is the most common bullying act, with 28% of respondents experiencing being ignored. Differences in the experience of bullying can be found between hospitals and among ethnicities. Emotional exhaustion also was correlated with bullying. The participants did not perceive bullying as affecting patient safety.
Back to Basics: Hand Hygiene and Surgical Hand Antisepsis
Authors: Spruce Lisa 
Published: October 2013

AbstractHealth care–associated infections (HAIs) are a significant issue in the United States and throughout the world, but following proper hand hygiene practices is the most effective and least expensive way to prevent HAIs. Hand hygiene is inexpensive and protects patients and health care personnel alike. The four general types of hand hygiene that should be performed in the perioperative environment are washing hands that are visibly soiled, hand hygiene using alcohol‐based products, surgical hand scrubs, and surgical hand scrubs using an alcohol‐based surgical hand rub product. Barriers to proper hand hygiene may include not thinking about it, forgetting, skin irritation, a lack of role models, or a lack of a safety culture. One strategy for improving hand hygiene practices is monitoring hand hygiene as part of a quality improvement project, but the most important aspect for perioperative team members is to set an example for other team members by following proper hand hygiene practices and reminding each other to perform hand hygiene.
Flow past a rotationally oscillating cylinder

Published: October 2013

AbstractFlow past a circular cylinder executing sinusoidal rotary oscillations about its own axis is studied experimentally. The experiments are carried out at a Reynolds number of 185, oscillation amplitudes varying from $\mathrm{\pi} / 8$ to $\mathrm{\pi} $, and at non-dimensional forcing frequencies (ratio of the cylinder oscillation frequency to the vortex-shedding frequency from a stationary cylinder) varying from 0 to 5. The diagnostic is performed by extensive flow visualization using the hydrogen bubble technique, hot-wire anemometry and particle-image velocimetry. The wake structures are related to the velocity spectra at various forcing parameters and downstream distances. It is found that the phenomenon of lock-on occurs in a forcing frequency range which depends not only on the amplitude of oscillation but also the downstream location from the cylinder. The experimentally measured lock-on diagram in the forcing amplitude and frequency plane at various downstream locations ranging from 2 to 23 diameters is presented. The far-field wake decouples, after the lock-on at higher forcing frequencies and behaves more like a regular Bénard–von Kármán vortex street from a stationary cylinder with vortex-shedding frequency mostly lower than that from a stationary cylinder. The dependence of circulation values of the shed vortices on the forcing frequency reveals a decay character independent of forcing amplitude beyond forcing frequency of ${\sim }1. 0$ and a scaling behaviour with forcing amplitude at forcing frequencies ${\leq }1. 0$. The flow visualizations reveal that the far-field wake becomes two-dimensional (planar) near the forcing frequencies where the circulation of the shed vortices becomes maximum and strong three-dimensional flow is generated as mode shape changes in certain forcing parameter conditions. It is also found from flow visualizations that even at higher Reynolds number of 400, forcing the cylinder at forcing amplitudes of $\mathrm{\pi} / 4$ and $\mathrm{\pi} / 2$ can make the flow field two-dimensional at forcing frequencies greater than ${\sim }2. 5$.
