AbstractChildhood and adolescence are critical periods of neural development and physical growth. The malnutrition and related medical complications resulting from eating disorders such as anorexia nervosa (AN), bulimia nervosa (BN) and eating disorder not otherwise specified may have more severe and potentially more protracted consequences during youth than during other age periods. The consensus opinion of an international workgroup of experts on the diagnosis and treatment of child and adolescent eating disorders is that (a) lower and more developmentally sensitive thresholds of symptom severity (e.g. lower frequency of purging behaviours, significant deviations from growth curves as indicators of clinical severity) be used as diagnostic boundaries for children and adolescents, (b) behavioural indicators of psychological features of eating disorders be considered even in the absence of direct self‐report of such symptoms and (c) multiple informants (e.g. parents) be used to ascertain symptom profiles. Collectively, these recommendations will permit earlier identification and intervention to prevent the exacerbation of eating disorder symptoms.

On iterative methods for the incompressible Stokes problem
Authors: ur Rehman M. , Geenen T. , Vuik C. , Segal G. , MacLachlan S. P. 
Published: February 2010

AbstractIn this paper, we discuss various techniques for solving the system of linear equations that arise from the discretization of the incompressible Stokes equations by the finite‐element method. The proposed solution methods, based on a suitable approximation of the Schur‐complement matrix, are shown to be very effective for a variety of problems. In this paper, we discuss three types of iterative methods. Two of these approaches use the pressure mass matrix as preconditioner (or an approximation) to the Schur complement, whereas the third uses an approximation based on the ideas of least‐squares commutators (LSC). We observe that the approximation based on the pressure mass matrix gives h‐independent convergence, for both constant and variable viscosity. Copyright © 2010 John Wiley & Sons, Ltd.
Homotopy solution for flow of a micropolar fluid on a continuous moving surface
Authors: Alomari A. K. , Noorani M. S. M. , Nazar R. 
Published: February 2010

AbstractIn this paper, the steady boundary layer flow and heat transfer of a micropolar fluid on an isothermal continuously moving plane surface is studied analytically. It is assumed that the microinertia density is variable and the viscous dissipation effect is taken into account. The system of nonlinear ordinary differential equations is solved analytically using the homotopy analysis method (HAM) and the results are obtained for various flow and heat transfer characteristics. By using HAM, accurate analytic series solutions are obtained in the whole spatial region. Also, a new suggestion for choosing the proper value of the auxiliary parameter ℏ in the convergence region is proposed. It is observed that the present solutions have higher accuracy when the residual error is obtained. The present results show that this algorithm is effective and can be similarly applied to other nonlinear equations. Copyright © 2010 John Wiley & Sons, Ltd.
Preliminary chemical and micromorphological observations on Urartu (800–600 B.C.) ceramics, eastern Turkey

Published: February 2010

AbstractAnatolia has long been a major pottery production center of the ancient world, dating back 7000 cal yr B.P. The Early Iron Age Urartu Kingdom (800–600 B.C.) of eastern Anatolia is known for the production of high‐quality pottery, but little is known regarding firing technology and manufacture of these ceramics. Here we present a preliminary study of Urartu ceramic micromorphology and chemistry and suggest that the Urartus had good knowledge of local geology and intentionally used chemical fluxes (Pb, Rb, and Li) to attain desired firing temperatures. The sophisticated production of Urartu ceramics is comparable to later high‐quality Roman pottery (terra sigillata) procured from the same area. © 2010 Wiley Periodicals, Inc.
Entropy‐supported marker selection and Mantel statistics for haplotype sharing analysis
Authors: Schulz Anke , Fischer Christine , Chang‐Claude Jenny , Beckmann Lars 
Published: February 2010

AbstractHaplotype sharing analysis is a well‐established option for the investigation of the etiology of complex diseases. The statistical power of haplotype association methods depends strongly on how the information of unobserved haplotypes can be captured by multilocus genotypes. In this study we combine an entropy‐based marker selection algorithm (EMS), with a haplotype sharing‐based Mantel statistics into a new algorithm. Genetic markers are iteratively selected by their multilocus linkage disequilibrium (LD), which is assessed by a normalized entropy difference. The initial marker set is gradually enlarged to increase the available information on the amount of sharing around a potential susceptibility marker. Markers are rejected from joint phasing if they do not increase the multilocus LD. In simulated candidate gene studies, the Mantel statistics combined with the new EMS performs as well or better at detecting the disease single nucleotide polymorphism—or in indirect association analysis its flanking markers—than the Mantel statistics without selection of markers prior to haplotype estimation and the Mantel statistics using sliding windows of size five. It is therefore appealing to apply our selection approach for haplotype‐based association analysis, since marker selection driven by the observed data avoids both the arbitrary choice of markers when using a fixed window size, as well as the estimation of haplotype block structure.

Published: February 2010

Abstractα‐Aminomethylation of (R)‐DIOZ‐alkylated (DIOZ=4‐isopropyl‐5,5‐diphenyloxazolidin‐2‐one) substrates is a key step in the asymmetric synthesis of β2‐amino acids, but it is unfortunately often accompanied by formation of transcarbamation by‐products. Aminomethylation was tested using a range of electrophiles, and the amount of by‐product formation was assessed in each case. Benzyl N‐[(benzyloxy)methyl]carbamate electrophile 3d is unable to form this by‐product due to its inherent benzyl substitution. Use of electrophile 3d showed an improved impurity profile in aminomethylation, thus leading to easier intermediate purification.

Published: February 2010

AbstractInjectable hydrogels may potentially be used for augmentation/regeneration of the lamina propria of vocal fold tissue. In this study, hyaluronic acid (HA) and dextran were chemically modified and subsequently crosslinked via formation of hydrazone bonds in phosphate buffer. Swelling ratios, degradation, and compressive moduli of the resulting hydrogels were investigated. It was found that the properties of HA‐dextran hydrogels were variable and the trend of variation could be correlated with the hydrogel composition. The biocompatibility of three injectable HA‐dextran hydrogels with different crosslinking density was assessed in the vocal fold region using a ferret model. It was found that HA‐dextran hydrogels implanted for three weeks stimulated mild foreign‐body reactions. Distinct tissue‐material interactions were also observed for hydrogels made from different formulations: the hydrogel with the lowest crosslinking density was completely degraded in vivo; while material residues were visible for other types of hydrogel injections, with or without cell penetration into the implantation depending on the hydrogel composition. The in vivo results suggest that the HA‐dextran hydrogel matrices can be further developed for applications of vocal fold tissue restoration. © 2010 Wiley Periodicals, Inc.

MM–GBSA binding free energy decomposition and T cell receptor engineering
Authors: Zoete V. , Irving M. B. , Michielin O. 
Published: February 2010

AbstractRecognition by the T‐cell receptor (TCR) of immunogenic peptides (p) presented by class I major histocompatibility complexes (MHC) is the key event in the immune response against virus infected cells or tumor cells. The major determinant of T cell activation is the affinity of the TCR for the peptide‐MHC complex, though kinetic parameters are also important. A study of the 2C TCR/SIYR/H‐2Kb system using a binding free energy decomposition (BFED) based on the MM–GBSA approach had been performed to assess the performance of the approach on this system. The results showed that the TCR‐p‐MHC BFED including entropic terms provides a detailed and reliable description of the energetics of the interaction (Zoete and Michielin, 2007). Based on these results, we have developed a new approach to design sequence modifications for a TCR recognizing the human leukocyte antigen (HLA)‐A2 restricted tumor epitope NY‐ESO‐1. NY‐ESO‐1 is a cancer testis antigen expressed not only in melanoma, but also on several other types of cancers. It has been observed at high frequencies in melanoma patients with unusually positive clinical outcome and, therefore, represents an interesting target for adoptive transfer with modified TCR. Sequence modifications of TCR potentially increasing the affinity for this epitope have been proposed and tested in vitro. T cells expressing some of the proposed TCR mutants showed better T cell functionality, with improved killing of peptide‐loaded T2 cells and better proliferative capacity compared to the wild type TCR expressing cells. These results open the door of rational TCR design for adoptive transfer cancer therapy. Copyright © 2010 John Wiley & Sons, Ltd.
Cataloging topologies of protein folding patterns
Authors: Konagurthu Arun S. , Lesk Arthur M. 
Published: February 2010

AbstractComparing and classifying protein folding patterns allows organizing the known structures, structure search and retrieval, and investigation of general principles of protein architecture. We have been developing a concise tableau representation of protein folding patterns, based on the order and contact patterns of elements of secondary structure: helices and strands of sheet (Lesk, 1995; Kamat and Lesk, 2007; Konagurthu et al., 2008). The tableaux provide a database, derived from the world‐wide protein data bank, mineable in studies of protein architecture, including: (i) determination of statistical properties of secondary structure contacts in an unbiased set of protein domains, (ii) investigations of the range of, and relationships among, protein topologies, (iii) investigation of the relationship between local structure of proteins and the complete folding topology, (iv) potential for fold identification from amino acid sequence, and (v) the basis for a complete enumeration of possible protein folding patterns, which can be compared with the corpus of known structures.

AbstractThis article presents the investigation of frequency and temporal coherence properties of distributed Bragg reflector laser. In this scheme, a square‐waveform voltage is applied to the phase section of the laser to tune optical wavelength, and delayed optical heterodyne technique is used for the analysis of spectral characteristics. Experiments show that lightwaves emitted from the same active region asynchronously are partially frequency and temporal coherent. When the two wavelengths are closer, the two waves are strongly coherent, and the coherence properties get weak as the delay time increases. © 2010 Wiley Periodicals, Inc.

Published: February 2010

AbstractAn optimum design approach for a highly efficient power amplifier (PA) using a packaged high‐power device is described.Large fundamental load impedance assisted by a simple second harmonic manipulation is explored to improve the efficiency when maintaining the power density. For demonstration of the performance, the PA is implemented using GaN HEMT device at 2.655 GHz. In the experiment, the fabricated PA achieves power‐added efficiency (PAE) of 64.3% at the saturated output power of 49.2 dBm. For 802.16e mobile worldwide interoperability for microwave access signal, the PA delivers the PAE of ∼31% and ACLR of −49 dBc at the 10 dB backed‐off power of 40 dBm after the digital feedback predistortion linearization. © 2010 Wiley Periodicals, Inc.

Design of triple‐mode bandpass filter using novel resonant structure
Authors: Mo Shao‐Guo , Yu Zhi‐Yuan , Zhang Long 
Published: February 2010

AbstractA novel triple‐mode hexagonal bandpass filter with capacitive loading is introduced in this article.The technique, adding an open stub with capacitive loading, is applied to enlarge the equivalent self‐capacitance of the resonator, which declines its resonant frequencies. A circular patch on the bottom layer is used to implement this technique. One‐mode resonant frequency is varied with the radius of the circular patch, whereas the other two modes are nearly not affected. This filter has a pair of transmission zeros, which are close to the passband, thus behaving a high selectivity. For method validation, a bandpass filter operating at 2.45 GHz is fabricated and measured. The experimental results are demonstrated and discussed. © 2010 Wiley Periodicals, Inc.

AbstractA reconfigurable printed log periodic dipole array (LPDA) is presented.It is shown that several frequency bands across a wide frequency range can be selected by switching the printed dipoles of the LPDA. In comparison with the reconfigurable printed dipole antenna introduced by the present authors before, the significant advantage of the reconfigurable LPDA lies in its flexibility in selecting the frequency bands with different bandwidths. The measurement results show that the reconfigurable LPDA operates over a frequency range of 3:1. The characteristics of the wideband reconfigurable LPDA is suitable for frequency switching in FCC ultra wideband allocation. © 2010 Wiley Periodicals, Inc.

AbstractA novel broadband dual‐frequency spider‐shaped dipole antenna for 2.4/5.2 GHz wireless local area networks (WLAN) is proposed. The antenna consists of a double‐sided printed dipole, whose long arms and short center‐stubs can produce dual bands and lead to good impedance matching in a wide dual‐band without external matching circuitry. For the experimental study, excellent performance for operating frequencies across 2240–3260 MHz and 4700–5970 MHz bands has been observed. Good radiation characteristics of dipole‐like patterns, and 2.6‐ and 4.6‐dBi peak antenna gains for the lower and upper bands, respectively, have been obtained. And this antenna could be easily printed and integrated on the system circuit board for WLAN applications. © 2010 Wiley Periodicals, Inc.
