Critical properties prediction based on a quartic equation of state
Authors: Zang Lian‐yun , Zhu Qing‐li , Yun Zhi 
Published: August 2010

AbstractA quartic equation of state (EOS) [Yun et al., Fluid Phase Equilibr. 2001; 187–188: 275–298] is used for predicting critical properties of pure substances. Parameters in the EOS are rewritten as functions of temperature (T in K), and there are totally eleven substance‐specific constants in the functions for each substance. Data of few experimental points including saturated vapour pressure, saturated liquid molar volume and evaporation enthalpy at some temperatures are required in this study to determine the substance‐specific constants in the EOS, while the knowledge of molecular structure is not necessary.Une équation d'état quartique (Yun et coll., «A new quartic equation of state,» Fluid Phase Equilib 187–188, 275–298 (2001)) est utilisée pour prédire les propriétés critiques des substances pures. Les paramètres de l'équation d'état sont réécrits comme des fonctions de la température (T, en K) et il y a un total de onze constantes propres aux substances dans les fonctions pour chaque substance. Les données de quelques points expérimentaux comprenant la pression de vapeur saturante, le volume molaire de la solution saturée et l'enthalpie d'évaporation à certaines températures sont requises dans cette étude dans le but de déterminer les constantes propres aux substances dans l'équation d'état, alors que la connaissance de la structure moléculaire n'est pas nécessaire.

Wavelet‐adaptive solvers on multi‐core architectures for the simulation of complex systems
Authors: Rossinelli Diego , Hejazialhosseini Babak , Bergdorf Michael , Koumoutsakos Petros 
Published: August 2010

AbstractWe build wavelet‐based adaptive numerical methods for the simulation of advection‐dominated flows that develop multiple spatial scales, with an emphasis on fluid mechanics problems. Wavelet‐based adaptivity is inherently sequential and in this work we demonstrate that these numerical methods can be implemented in software that is capable of harnessing the capabilities of multi‐core architectures while maintaining their computational efficiency. Recent designs in frameworks for multi‐core software development allow us to rethink parallelism as task‐based, where parallel tasks are specified and automatically mapped onto physical threads. This way of exposing parallelism enables the parallelization of algorithms that were considered inherently sequential, such as wavelet‐based adaptive simulations. In this paper we present a framework that combines wavelet‐based adaptivity with the task‐based parallelism. We demonstrate the promising performance obtained by simulating various physical systems on different multi‐core architectures using up to 16 cores. Copyright © 2010 John Wiley & Sons, Ltd.
Spatial embedding and the structure of complex networks
Authors: Bullock S. , Barnett L. , Di Paolo E. A. 
Published: August 2010

AbstractWe review and discuss the structural consequences of embedding a random network within a metric space such that nodes distributed in this space tend to be connected to those nearby. We find that where the spatial distribution of nodes is maximally symmetrical some of the structural properties of the resulting networks are similar to those of random nonspatial networks. However, where the distribution of nodes is inhomogeneous in some way, this ceases to be the case, with consequences for the distribution of neighborhood sizes within the network, the correlation between the number of neighbors of connected nodes, and the way in which the largest connected component of the network grows as the density of edges is increased. We present an overview of these findings in an attempt to convey the ramifications of spatial embedding to those studying real‐world complex systems. © 2010 Wiley Periodicals, Inc.

Interaction between a dislocation and monovalent anion in various alkali halide crystals
Authors: Kohzuki Y. 
Published: August 2010

AbstractIt was investigated from (L0/L)2 versus ϕ0 curve that the Friedel relation between the effective stress and the average length of dislocation segments, L, is appropriate for the interaction between a dislocation and the monovalent anion in various alkali halides single crystals (NaCl: Br‐, NaBr: Cl‐ or I‐, KCl: Br‐or I‐, and RbCl: Br‐ or I‐). Here, L0 represents the average spacing of monovalent anions on a slip plane and ϕ0 is the bending angle at which the dislocation breaks away from the anion at the temperature of 0 K. This is because the anions are the weak obstacles such as impede the dislocation at ϕ0 above about 150 degrees, where the Friedel relation agrees with the Fleischer one (L02 = L2(π–ϕ0)/2). Furthermore, the values of (L /L0) were found to be within 4.05 to 5.87 for the crystals. (© 2010 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
Impedance analysis and high temperature conduction mechanism of flux grown Pb(Zn1/3Nb2/3)0.91Ti0.09O3 single crystal
Authors: Singh B. K. , Kumar B. 
Published: August 2010

AbstractThe electrical properties of Pb(Zn1/3 Nb2/3)0.91Ti0.09O3 single crystals over a wide range of frequencies (20 Hz to 2 MHz) and temperature (30 to 490 °C) were studied using impedance spectroscopic technique. A strongly frequency dependant Debye type relaxation process in crystals was observed. The activation energy for relaxation was found to be 1.72 eV. The nature of Cole‐Cole plot reveals the contribution of only grain (bulk) effect in the sample. The temperature dependant conductivity was found to different in different temperature regions, which shows the presence of different carrier for conduction. The activation energy for conduction in the order of 1.69 eV suggested that the conduction process in higher temperature region is governed by the presence of lead vacancy defect in the sample. Further, the negative temperature thermistor behaviour of the system was explored and various associated parameters were calculated. (© 2010 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
Minimal Euclidean distance‐inspired optimal and suboptimal modulation schemes for vector OFDM system
Authors: Huang Xin‐Lin , Wang Gang , Hu Fei 
Published: August 2010

AbstractIn single‐input and single‐output (SISO) systems, the vector orthogonal frequency division multiplexing (VOFDM) has been proposed to reduce the cyclic prefix length, whereas the precoded OFDM has been proposed to overcome spectral‐null channels. However, VOFDM does not show robustness to spectral‐null channels, and the precoded OFDM system has expanded data rate. This work proposes the optimal and suboptimal modulation schemes in vector OFDM systems with knowledge of the channel impulse response (CIR) in order to reduce the bit error rate (BER). As the BER performance is determined by the diversity of the received vector symbols, the proposed modulation scheme mainly concerns the minimal Euclidean distance of all the possible received vector symbols. Through the analysis of the vector input and output equations, we derive the Euclidean distance of the received vector symbols. Then, we propose optimal and suboptimal modulation schemes in VOFDM system to overcome spectral‐null channels by improving the minimal Euclidean distance. Both theoretical performance analysis and simulation results are presented to show the robustness of our system. Finally, we conduct a compared performance analysis of the proposed VOFDM system, the conventional precoded OFDM system, and the conventional VOFDM system. Copyright © 2010 John Wiley & Sons, Ltd.
Recombinant EDA or Sonic Hedgehog rescue the branching defect in Ectodysplasin A pathway mutant salivary glands in vitro
Authors: Wells K.L. , Mou C. , Headon D.J. , Tucker A.S. 
Published: August 2010

AbstractHypohidrotic ectodermal dysplasia (HED) is characterized by defective ectodermal organ development. This includes the salivary glands (SGs), which have an important role in lubricating the oral cavity. In humans and mice, HED is caused by mutations in Ectodysplasin A (Eda) pathway genes. Various phenotypes of the mutant mouse EdaTa/Ta, which lacks the ligand Eda, can be rescued by maternal injection or in vitro culture supplementation with recombinant EDA. However, the response of the SGs to this treatment has not been investigated. Here, we show that the submandibular glands (SMGs) of EdaTa/Ta mice exhibit impaired branching morphogenesis, and that supplementation of EdaTa/Ta SMG explants with recombinant EDA rescues the defect. Supplementation of EdardlJ/dlJ SMGs with recombinant Sonic hedgehog (Shh) also rescues the defect, whereas treatment with recombinant Fgf8 does not. This work is the first to test the ability of putative Eda target molecules to rescue Eda pathway mutant SMGs. Developmental Dynamics 239:2674–2684, 2010. © 2010 Wiley‐Liss, Inc.
Developmental expression of Bdnf, Ntf4/5, and TrkB in the mouse peripheral taste system
Authors: Huang Tao , Krimm Robin F. 
Published: August 2010

AbstractBrain‐derived neurotrophic factor (BDNF), neurotrophin‐4 (NT4), and their TrkB receptor regulate taste system development. To determine where and when gustatory neurons come in contact with these important factors, temporospatial expression patterns of Bdnf, Ntf4/5, and TrkB in the peripheral taste system were examined using RT‐PCR. In the lingual epithelium, Ntf4/5 mRNA expression was higher than that of Bdnf at embryonic day 12.5 (E12.5), and the expression of both factors decreased afterwards. However, Ntf4/5 expression decreased at an earlier age than Bdnf.
Bdnf and Ntf4/5 are expressed in equal amounts at E12.5 in geniculate ganglion, but Bdnf expression increased from E14.5 to birth, whereas Ntf4/5 expression decreased. These findings indicate that NT4 functions at early embryonic stages and is derived from different sources than Bdnf. TrkB expression in the geniculate ganglion is robust throughout development and is not a limiting factor for neurotrophin function in this system.

Authors: da Silva Rodrigo Amorim Bezerra , Rabelo Adriano César , Munoz Rodrigo Alejandro Abarza , Richter Eduardo Mathias 
Published: August 2010

AbstractThis work describes the construction, characterization, and application of a three‐electrode‐integrated sensor into a micropipette tip. The three electrodes (working, pseudoreference and counter) are positioned at the end of a micropipette tip. The working electrode (graphite composite or gold microfiber) is placed inside the micropipette tip and the pseudo‐reference and counter electrodes outside (diametrically opposed sides). This approach is candidate for portable applications and allows the analysis and studies in low‐volume solutions (ca. 10 µL) which are useful for waste minimization and development of clean analytical methods. In addition, the three‐electrode‐integrated sensor can be easy used as detector in flow injection system through its direct joining at the end of polyethylene tubing of the FIA system.
Recombinant clotting factor VIII concentrates: Heterogeneity and high‐purity evaluation
Authors: D'Amici Gian Maria , Timperio Anna Maria , Gevi Federica , Grazzini Giuliano , Zolla Lello 
Published: August 2010

AbstractFactor VIII is an important glycoprotein involved in hemostasis. Insertion of expression vectors containing either the full‐length cDNA sequence of human factor VIII (FLrFVIII) or B‐domain deleted (BDDrFVIII) into mammalian cell lines results in the production of recombinant factor VIII (rFVIII) for therapeutic usage. Three commercially available rFVIII concentrates (Advate®, Helixate NexGen® and Refacto®), either FLrFVIII or BDDrFVIII, were investigated by 1‐ and 2‐DE and MS. The objective of this study was to compare the heterogeneity and the high purity of both rFVIII preparations before and after thrombin digestion. In particular, the 2‐D gel was optimized to better highlight the presence of contaminants and many unexpected proteins. Recombinant strategies consisting of insertion of expression vectors containing BDDrFVIII and FLrFVIII resulted in homogeneous and heterogeneous protein products, respectively, the latter consisting in a heterogeneous mixture of various B‐domain‐truncated forms of the molecule. Thrombin digestion of all the three rFVIII gave similar final products, plus one unexpected fragment of A2 domain missing 11 amino acids. Regarding the contaminants, Helixate NexGen® showed the presence of impurities, such as Hsp70 kDa, haptoglobin and proapolipoprotein; Refacto® showed glutathione S‐transferase and β‐lactamase, whereas Advate® apparently did not contain any contaminants. The proteomic approach will contribute to improving the quality assurance and manufacturing processes of rFVIII concentrates. In this view, the 2‐DE is mandatory for revealing the presence of contaminants.
Employing Volterra filters in the ADPCM technique for speech coding: a comprehensive investigation
Authors: Alipoor Gh. , Savoji M. H. 
Published: August 2010

AbstractAlthough linear filters are useful in a various applications in the context of speech processing, there are several evidences for existence of nonlinearity in speech signals. Our main aim is to launch a comprehensive investigation into the exploitation of nonlinear Volterra filters in the context of the ADPCM‐based speech coding technique, using two methods of forward prediction, based on the LS criterion, and backward prediction, based on both LMS and RLS adaptation algorithms. In any case, after solving some innate problems, for example, ill‐conditioning and instability, schemes for optimum exploitation of nonlinear prediction are developed and simulation results are provided, tested with several performance criteria. With forward prediction a scheme is developed to detect and flag those frames for which, after stabilizing, including the quadratic predictor is beneficial. Scalar and vector quantisation methods are used for quantising the residual signal and the filter parameters, respectively. The results show that using this scheme a negligible improvement (up to 0.62 dB in the SNR) can be achieved, in spite of the increase in bit rate and complexity. With backward prediction two frame‐based schemes are developed in which for each frame, after examining a set of quadratic filters, the best filter in the sense of the best quality of the reconstructed speech is selected. The ultimate schemes result in an improvement of up to 1.5 dB in the overall SNR of the reconstructed speech at the cost of a slight increase in the bit‐rate, a short delay and a demanding increase in the complexity.

Liposomal incorporation of rose essential oil by a supercritical process
Authors: Wen Zhen , You Xinkui , Jiang Linzhi , Liu Bo , Zheng Zongkun , Pu Yitao , Cheng Bo 
Published: August 2010

AbstractThis study was conducted to investigate the possibility of applying a supercritical process to incorporate rose essential oil into liposomes. By rapid expansion of the supercritical solution of the lipid materials and rose essential oil into a surfactant solution, the liposomes entrapping rose essential oil were formed. In this process, the surfactant provided stabilization for liposomes by preventing flocculation and agglomeration resulting from particle collisions during the spraying process. The encapsulating performance and particle size distribution of liposomes could be controlled by changing pre‐expansion and expansion processing conditions. According to analysis by differential scanning calorimetry (DSC), the morphology and particle size, the liposomes formed were double‐layered vesicles entrapping the rose essential oil with a particle size of less than 100 nm. Compared with the liposomes prepared by thin‐film dispersion, the liposomes formed by the supercritical process exhibited higher encapsulation efficiency and smaller particle size with a unimodal distribution, which achieved the standards of Chinese Pharmacopoeia. The results suggest the supercritical process facilitated a more controllable operation for self‐assembly of liposomes incorporating heat‐sensitive components from natural products in the CO2 medium.

Published: August 2010

AbstractSandalwood (Santalum album L.) is a traditional incense, and its essential oil is used in fragrances. The hexane extract from Indian sandalwood chips had a sandalwood odour similar to sandalwood chips, but it clearly differed from that of commercial essential oil. By fractional distillation of the extract under reduced pressure, a fraction was obtained that had a sandalwood‐like odour and contained several unknown formyl compounds as the main constituents. Santalyl formates were isolated as new components from this fraction by chromatography and characterized by 1H‐ and 13C‐NMR spectroscopy. These constituents were less abundant in the commercial essential oil than in the hexane extract. Santalyl formates were synthesized from the corresponding alcohols.
Inference for regression models with errors from a non‐invertible MA(1) process
Authors: Chen Mei‐Ching , Davis Richard A. , Song Li 
Published: August 2010

AbstractThis paper considers maximum likelihood estimation in a regression model when the errors follow a first‐order moving average model which is non‐invertible or nearly non‐invertible. The latter corresponds to a moving average parameter θ that is equal to or close to 1. The joint limiting distribution of the maximum likelihood estimators b̂ and $\hat\theta$ of the regression parameter vector b and the moving average parameter θ is described. Unlike the case with standard time series models, the limiting distribution of b̂ depends on whether or not θ is being estimated. Specifically, the limit distribution of b̂ is non‐normal if θ is also being estimated and is normal if θ is unestimated and equal to 1. The asymptotic behavior of the generalized likelihood ratio statistic for testing θ = 1 vs. θ < 1 is also studied and shown to perform well compared to the locally best invariant unbiased test of Tanaka (1990). We also indicate extensions to seasonal moving average models with a unit root. Copyright © 2010 John Wiley & Sons, Ltd.
