ObjectiveIsolated GH deficiency (IGHD) could provide a model to investigate the influence of GH deficiency per se and the effect of GH replacement therapy without the influence from other pituitary hormone deficiencies or their treatment. The aim of this study is to address the questions about differences between IGHD and multiple pituitary hormone deficiencies (MPHDs) in clinical presentation and in responsiveness to GH treatment.DesignA nationwide surveillance study was carried out to describe the difference in the clinical presentation and responsiveness to GH treatment of patients with IGHD and MPHDs.MethodsThe Dutch National Registry of GH Treatment in Adults was founded in 1998 to gain more insight into long-term efficacy and safety of GH therapy. Out of 2891 enrolled patients, 266 patients with IGHD at the start of GH treatment were identified and compared with 310 patients with MPHDs. Cardiovascular indices will be investigated at baseline and during long-term follow-up, including body composition, lipid profile, glucose metabolism, blood pressure, and morbidity.ResultsPatients with IGHD and MPHDs were demonstrated to be different entities at clinical presentation. Metabolically, patients with MPHDs had a larger waist circumference, lower HDL cholesterol level, and higher triglyceride level. The effect of GH treatment was comparable between patient groups. GH seems to protect against rising lipid levels and blood pressure, even after excluding patients using corresponding concomitant medication. The risk for cardiovascular disease or diabetes mellitus during follow-up was not different between patients with IGHD and MPHDs.ConclusionsPatients with IGHD had a less impaired metabolic profile than patients with MPHDs at baseline. Influence of other pituitary hormone replacement therapies on the effect of GH treatment is not demonstrated.

ABSTRACTMn-doped CeO2 electrolytes formulated as Ce1-xMnxO2-x (0.05 ≤ x ≤ 0.25) were prepared via soft chemical technique which involved co-precipitation of Mn2+ and Ce4+ using oxalic acid as the precipitant. The optimized pH for a stable incorporation of Mn dopant into ceria was found to be pH = 10. The solubility limit of MnO in the CeO2 fluorite lattice structure was suggested to be x = 0.20. The phase composition, morphology properties and elemental analysis of the oxalate and derived-powder was characterized using X-ray diffraction, SEM and X-ray fluorescence (XRF) respectively. The electrical conductivity of sintered samples of Mn-doped CeO2 ceramics were investigated in air using AC impedance spectroscopy. The bulk conductivities of the Mn-doped CeO2 ceramics sintered at 1200 °C at a test temperature of 800 °C were determined to be 4.223 x 10-4 ohm-1 cm-1 for Mn content x = 0.10 with activation energy, Ea = 0.88 eV.

Published: May 2014

ABSTRACTThe formation of nickel germanide has been examined over a range of low temperatures (200-400 °C) in an attempt to minimize the thermal budget for the process. Cross-sectional Transmission Electron Microscopy (TEM) was used to determine the texture of the germanide layer and the morphology and constituent composition of the Ge/NiGe interface. The onset and completion of reaction between Ni and Ge were identified by means of a heated stage in combination with in-situ x-ray diffraction (XRD) measurements. The stages of reaction were also monitored using measurements of sheet resistance of the germanides by the Van der Pauw technique. The results have shown that the minimum temperature for the initiation of reaction of Ni and Ge to form NiGe was 225 °C. However, an annealing temperature > 275 °C was necessary for the extensive (and practical) formation of NiGe. Between 200 and 300 °C, the duration of annealing required for the formation of NiGe was significantly longer than at higher temperatures. The stoichiometry of the germanide was very close to NiGe (1:1) as determined using energy dispersive spectroscopy (EDS).

Published: May 2014

ABSTRACTThiolate-gold nanoclusters exhibit unique optical, magnetic and chiral properties, which are attractive for novel applications in nanotechnology. A fundamental challenge facing these nanomaterials is being able to study and understand their physical properties in various experimental conditions. To overcome this, extended X-ray absorption fine structure (EXAFS) spectroscopy can be employed to probe the Au local structure of thiolate-gold nanoclusters in a variety of conditions, providing valuable structural information from multiple bonding environments (i.e. metal-metal and metal-ligand interactions). This study discusses a methodology for conducting a multishell EXAFS fitting analysis that can be implemented for thiolate-gold nanocluster systems. Specifically, experimental and simulated EXAFS data for Au36(SR)24 nanoclusters are examined with a total of 5 scattering paths fitted to the experimental data.
The Nematic Character of a Hidden Ordered State revealed by Magnetic Fields.
Authors: Riseborough Peter S. , Magalhaes S. G. , Calegari E.J. 
Published: May 2014

ABSTRACTWe examine a novel phase of the underscreened Anderson lattice Model that might pertain to the ”Hidden Ordered” phase of URu2Si2. We show that the system breaks spin-rotational invariance below the critical temperature and spontaneously selects a preferred axis of spin quantization. As a result, the low temperature phase exhibits a magnetic anisotropy, where the electronic properties depend not only on the magnitude of the magnetic field but also on the orientation of the applied field relative to the axis of quantization. The results are discussed in the context of recent experimental findings on URu2Si2.

Published: May 2014

Objective To identify the contribution of TGFA gene variants to the risk of nonsyndromic cleft lip with or without palate (NS-CL±P). Design The samples were from 142 Korean NS-CL±P families and 119 control parents having nonaffected children. Minor allele frequency, heterozygosity, and χ2 test for Hardy-Weinberg equilibrium were calculated for each of 10 selected single-nucleotide polymorphisms (SNPs). Ten SNPs were used to examine the association of case-parent trios with the transmission disequilibrium test (TDT) and conditional logistic regression models (CLRMs). Both allelic and genotypic TDTs for individual SNPs and sliding windows of haplotypes consisting of two to five SNPs were tested using family- and haplotype-based association test programs. Genotypic odd ratios (GORs) were obtained from CLRMs using STATA software. The parent-of-origin effect was evaluated for 10 SNPs, and a comparison between 218 case parents and 119 control parents was performed to investigate paternal and maternal ORs. Results Family-based TDT and haplotype analysis exhibited no statistical significance, but a relatively meaningful association was shown with rs3771497 (all P < .05; two SNPs, rs3771497 and rs3755377; five SNPs, rs3771497, rs3755377, rs3771485, rs11466212, and rs3771475). G/G homozygotes at rs3771497 have a significant decreased risk of NS-CL±P (GOR = 0.30, P < .01). No SNPs showed parent-of-origin effects. However, in the comparison between case parents and control parents, a single-marker analysis of maternal line showed a significant association with NS-CL±P in rs3771497 ( P < .001, recessive model). Conclusion The association of the TGFA gene with NS-CL±P in Korean populations was not clearly found. However, the etiologic effect of the TGFA gene on NS-CL±P patients should be investigated in terms of maternal genotype influence.

Objective To compare health-related quality of life and oral health–related quality of life between nonsyndromic individuals with and without cleft lip and/or cleft palate and to identify the most affected quality of life dimensions in individuals with cleft lip and/or palate. Design Systematic review and meta-analysis were conducted. Of the 314 identified citations, 23 articles were submitted to quality assessment. Data from nine studies on health-related quality of life and six on oral health–related quality of life were extracted for meta-analysis. Main Outcome Measures Pooled mean differences of health-related quality of life between adults with and without cleft lip and/or palate, pooled means of health-related quality of life dimensions of children and adults with cleft lip and/or palate and oral health–related quality of life dimensions of children and adolescents with cleft lip and/or palate with a 95% confidence interval were calculated. Results Quality assessment revealed methodological differences between studies. Lack of subgroup stratification and absence of control for confounders were the main limitations. Heterogeneity was detected on the comparison of oral health–related quality of life and health-related quality of life between children with and without cleft lip and/or palate, and oral health–related quality of life between adolescents with and without cleft lip and/or palate. A random-effect model showed a significant difference on health-related quality of life between adults with and without cleft lip and/or palate (mean difference = 0.10; 95% confidence interval, 0.16 to 0.05). Psychological health (mean, 78.9; 95% confidence interval, 70.1 to 87.7) and vitality (mean, 68.1; 95% confidence interval, 48.0 to 88.1) were the most affected health-related quality of life dimensions in children and adults with cleft lip and/or palate, respectively. Means of health-related quality of life dimensions in children and adults with cleft lip and/or palate and oral health–related quality of life in children and adolescents with cleft lip and/or palate varied yet did not differ in indirect comparisons. Conclusion The presence of cleft lip and/or palate negatively affected the health-related quality of life of adults, mainly on psychosocial dimensions.
The Role of Corporate Social Responsibility (CSR) Assurance in Investors' Judgments When Managerial Pay is Explicitly Tied to CSR Performance
Authors: Brown-Liburd Helen , Zamora Valentina L. 
Published: May 2014

SUMMARY
While corporate social responsibility (CSR) reports are intended to faithfully represent CSR performance, voluntarily disclosed CSR information tends to be positive, and demand is rising for both independent assurance and integrated reporting of CSR. However, the supply of CSR assurance is not widespread in the United States, and CSR performance information remains largely separated from supporting and governance information. We thus examine the role of CSR assurance when information on CSR investment level is integrated with information on whether managerial pay is explicitly tied to sustainability. While a firm may report a high level of CSR investment to indicate an authentic commitment to CSR, investors may become skeptical of reported information if managerial pay is explicitly tied to CSR performance. Such pay-for-CSR-performance provides managers with greater incentives to overinvest in CSR and thereby report strong CSR performance. In turn, investors will seek CSR assurance as a disclosure credibility signal. Accordingly, we find that, in the presence of pay-for-CSR-performance and high CSR investment level, investors' stock price assessments are greater only when CSR assurance is also present. Our findings highlight the importance of examining CSR disclosure factor interaction effects, and provide support for the expansion of CSR assurance and integrated reporting.

The Effect of Simplified Adhesives on the Bond Strength to Dentin of Dual-cure Resin Cements
Authors: Shade AM , Wajdowicz MN , Bailey CW , Vandewalle KS 
Published: May 2014

SUMMARY
The purpose of this study was to compare the shear bond strengths to dentin of two dual-cure resin cements, one with a unique initiator, NX3 (Kerr Corp), and the other with a traditional redox-initiator system, Calibra (Dentsply), when used in combination with simplified or nonsimplified adhesive agents. The two dual-cure resin cements, in either self- or dual-cure activation modes, were bonded to human dentin with four dental adhesives to create 16 subgroups of 10 specimens each. After 24 hours of storage in distilled water at 37°C, the specimens were tested in shear in a universal testing machine. With both NX3 and Calibra, bond strengths significantly increased when the specimens were dual cured. In addition, with either cement in either mode, the nonsimplified adhesives performed significantly better than did the simplified adhesive bonding agents. When used specifically with simplified adhesives in either cure mode, NX3 did not produce significantly higher bond strengths than did Calibra. In general, lower dentin bond strengths were found with simplified adhesives or self-cure activation with either resin cement.
Epsilon Nielsen coincidence theory
Authors: Fenille Marcio 
Published: May 2014

AbstractWe construct an epsilon coincidence theory which generalizes, in some aspect, the epsilon fixed point theory proposed by Robert Brown in 2006. Given two maps f, g: X → Y from a well-behaved topological space into a metric space, we define µ ∈(f, g) to be the minimum number of coincidence points of any maps f 1 and g 1 such that f 1 is ∈ 1-homotopic to f, g 1 is ∈ 2-homotopic to g and ∈ 1 + ∈ 2 < ∈. We prove that if Y is a closed Riemannian manifold, then it is possible to attain µ ∈(f, g) moving only one rather than both of the maps. In particular, if X = Y is a closed Riemannian manifold and idY is its identity map, then µ ∈(f, idY) is equal to the ∈-minimum fixed point number of f defined by Brown. If X and Y are orientable closed Riemannian manifolds of the same dimension, we define an ∈-Nielsen coincidence number N ∈(f, g) as a lower bound for µ ∈(f, g). Our constructions and main results lead to an epsilon root theory and we prove a Minimum Theorem in this special approach.
Game saturation of intersecting families
Authors: Patkós Balázs , Vizer Máté 
Published: May 2014

AbstractWe consider the following combinatorial game: two players, Fast and Slow, claim k-element subsets of [n] = {1, 2, …, n} alternately, one at each turn, so that both players are allowed to pick sets that intersect all previously claimed subsets. The game ends when there does not exist any unclaimed k-subset that meets all already claimed sets. The score of the game is the number of sets claimed by the two players, the aim of Fast is to keep the score as low as possible, while the aim of Slow is to postpone the game’s end as long as possible. The game saturation numbers, gsatF(IIn,k) and gsatS(IIn,k), are the score of the game when both players play according to an optimal strategy in the cases when the game starts with Fast’s or Slow’s move, respectively. We prove that $\Omega _k (n^{k/3 - 5} ) \leqslant gsat_F (\mathbb{I}_{n,k} ),gsat_S (\mathbb{I}_{n,k} ) \leqslant O_k (n^{k - \sqrt {k/2} } )$.
EIT phenomenon for the three-level hydrogen atoms and its application to the era of cosmological recombination
Authors: Solovyev Dmitry , Dubrovich Victor 
Published: May 2014

AbstractThe paper evaluates the contribution of the electromagnetically induced transparency (EIT) phenomenon to the processes of the microwave background (CMB) formation in early universe. We found the additional function f to the integrated line absorption coefficient. This makes it the necessity to upgrade the Sobolev escape probability: p ij (τ S) → p ij (τ S · (1 + f)). We calculated the magnitude of the function f for different schemes of the hydrogen atom in the three-level approximation in terms of the field parameters. The electric field amplitudes are defined using the CMB distribution. We found that the contribution of f can be significant in some cases.
On some new forms of lattice integrable equations
Authors: Babalic Corina , Carstea Adrian 
Published: May 2014

AbstractInspired by the forms of delay-Painleve equations, we consider some new differential-discrete systems of KdV, mKdV and Sine-Gordon — type related by simple one way Miura transformations to classical ones. Using Hirota bilinear formalism we construct their new integrable discretizations, some of them having higher order. In particular, by this procedure, we show that the integrable discretization of intermediate sine-Gordon equation is exactly lattice mKdV and also we find a bilinear form of the recently proposed lattice Tzitzeica equation. Also the travelling wave reduction of these new lattice equations is studied and it is shown that all of them, including the higher order ones, can be integrated to Quispel-Roberts-Thomson (QRT) mappings.
Finitely continuous differentials on generalized power series
Authors: Huang I-Chiau 
Published: May 2014

Abstract
Let κ[[eG]] be the field of generalized power series with exponents in a totally ordered Abelian group G and coefficients in a field κ. Given a subgroup H of G such that G/H is finitely generated, we construct a vector space ΩG/H of differentials as a universal object in certain category of κ[[eH]]-derivations on κ[[eG]]. The vector space ΩG/H together with logarithmic residues gives rise to a framework for certain combinatorial phenomena, including the inversion formula for diagonal delta sets.

Authors: Belbachir Hacène , Komatsu Takao , Szalay László 
Published: May 2014

Abstract
Our main purpose is to describe the recurrence relation associated to the sum of diagonal elements laying along a finite ray crossing Pascal’s triangle. We precise the generating function of the sequence of described sums. We also answer a question of Horadam posed in his paper [Chebyshev and Pell connections, Fibonacci Quart. 43 (2005), 108–121]. Further, using Morgan-Voyce sequence, we establish the nice identity $F_{n + 1} - iF_n = i^n \sum\limits_{k = 0}^n {(_{2k}^{n + k} )( - 2 - i)^k } $ of Fibonacci numbers, where i is the imaginary unit. Finally, connections to continued fractions, bivariate polynomials and finite differences are given.
Property (A) of third-order advanced differential equations
Authors: Džurina J. , Baculíková B. 
Published: May 2014

Abstract
In the paper we offer criteria for property (A) of the third-order nonlinear functional differential equation with advanced argument $(a(t)(x'(t))^\gamma )'' + p(t)f(x(\sigma (t))) = 0,$, where $\mathop \smallint \limits^\infty a^{ - 1/\gamma } (s)ds = \infty $. We establish new comparison theorems for deducing property (A) of advanced differential equations from that of ordinary differential equations without deviating argument. The presented comparison principle fill the gap in the oscillation theory.

Abstract
In this paper, oscillatory and asymptotic properties of solutions of nonlinear fourth order neutral dynamic equations of the form $(r(t)(y(t) + p(t)y(\alpha _1 (t)))^{\Delta ^2 } )^{\Delta ^2 } + q(t)G(y(\alpha _2 (t))) - h(t)H(y(\alpha _3 (t))) = 0(H)$ and $(r(t)(y(t) + p(t)y(\alpha _1 (t)))^{\Delta ^2 } )^{\Delta ^2 } + q(t)G(y(\alpha _2 (t))) - h(t)H(y(\alpha _3 (t))) = f(t),(NH)$ are studied on a time scale $\mathbb{T}$ under the assumption that $\int\limits_{t_0 }^\infty {\tfrac{t}
{{r(t)}}\Delta t = \infty }
$ and for various ranges of p(t). In addition, sufficient conditions are obtained for the existence of bounded positive solutions of the equation (NH) by using Krasnosel’skii’s fixed point theorem.
Concentration compactness of a Landau-Lifschitz type energy with radial structure
Authors: Wang Bei , Cai Yuze , Lei Yutian 
Published: May 2014

Abstract
This paper is concerned with the asymptotic behavior of a p-Landau-Lifschitz type functional with radial structure as parameter goes to zero. We study the concentration compactness properties in the case of p ≥ n where n is the dimension. By analyzing the functional globally, we show that the singularity of p-Landau-Lifschitz energy concentrates on the origin.
Boundedness of the extremal solution for some p-Laplacian problems
Authors: Wei Long 
Published: May 2014

Abstract
We investigate the regularity of extremal solutions to some p-Laplacian Dirichlet problems with strong nonlinearities. Under adequate assumptions we prove the smoothness of the extremal solutions for some classes of nonlinearities. Our results suggest that the extremal solution’s boundedness for some range of dimensions depends on the nonlinearity f.

Published: May 2014

Abstract
Quite recently Jankov and Pogány [JANKOV, D.—POGÁNY, T. K.: Integral representation of Schlömilch series, J. Classical Anal. 1 (2012) 75–84] derived a double integral representation of the Kapteyn-type series of Bessel functions. Here we completely describe the class of functions Λ = {α}, which generate the mentioned integral representation in the sense that the restrictions $\alpha |_\mathbb{N} = (\alpha _n )_{n \in \mathbb{N}} $ is the sequence of coefficients of the input Kapteyn-type series.
