Tobacco intervention practices of licensed psychologists
Authors: Leffingwell Thad R. , Babitzke Alison C. 
Published: December 2005

AbstractTobacco dependence is a serious public health concern. The U.S. Department of Health and Human Services has issued a practice guideline of best practices to encourage all health care providers to intervene with tobacco‐dependent individuals they encounter. Psychologists may be ideally suited to implement brief tobacco interventions due to their expertise in behavior change strategies and interpersonal counseling skills. This study sought to investigate current tobacco assessment and intervention practices and perceptions of responsibility for tobacco intervention among a regional sample of licensed, practicing psychologists. Results suggest that a majority of psychologists fall far short of the ideal best practices recommended in the practice guideline, and many are unaware of the availability of the guidelines. Further, psychologists in this study perceived tobacco intervention to be a greater responsibility of physicians and other health care providers than of psychologists and other mental health professionals. © 2005 Wiley Periodicals, Inc.

Mechanisms of mindfulness
Authors: Shapiro Shauna L. , Carlson Linda E. , Astin John A. , Freedman Benedict 
Published: December 2005

AbstractRecently, the psychological construct mindfulness has received a great deal of attention. The majority of research has focused on clinical studies to evaluate the efficacy of mindfulness‐based interventions. This line of research has led to promising data suggesting mindfulness‐based interventions are effective for treatment of both psychological and physical symptoms. However, an equally important direction for future research is to investigate questions concerning mechanisms of action underlying mindfulness‐based interventions. This theoretical paper proposes a model of mindfulness, in an effort to elucidate potential mechanisms to explain how mindfulness affects positive change. Potential implications and future directions for the empirical study of mechanisms involved in mindfulness are addressed. © 2005 Wiley Periodicals, Inc. J Clin Psychol 62: 373–386, 2006.
Non‐linearity influences on the axial secular‐motion spectrum of ions confined in a Fourier transform ion trap mass spectrometer. Experimental studies
Authors: Carette M. , Zerega Y. 
Published: December 2005

AbstractA Fourier transform operating mode is applied to an ion trap. The trap is truncated at 2r0 and presents unwanted defects that induce confinement electric‐field non‐linearities.Ion axial secular‐motion spectrum is examined by experiments near the resonance line βz = 0.5. Ion‐loss processes and ion axial‐motion peak splitting are observed.In the non‐linear ion trap, the ion‐motion frequency depends on its initial conditions in position and velocity. This brings an enlargement of the motion‐frequency peak and limits the resolution.With a 2r0 truncated ion trap, the Fourier transform ion trap mass spectrometer (FTIT‐MS) leads experimentally to a mass resolution of about 4000 at 130 u.

AbstractCysteine sulfonic acid‐containing peptides, being typical acidic peptides, exhibit low response in matrix‐assisted laser desorption/ionization (MALDI) mass spectrometry. In this study, matrix conditions and the effect of diammonium hydrogencitrate (DAHC) as additive were investigated for ionization of cysteine sulfonic acid‐containing peptides in MALDI. A matrix‐free ionization method, desorption/ionization on porous silicon (DIOS), was also utilized to evaluate the effect of DAHC. When equimolar three‐component mixtures of peptides carrying free cysteine, cysteine sulfonic acid, and carbamidomethyl cysteine were measured by MALDI using a common matrix, α‐cyano‐4‐hydroxycinnamic acid (CHCA), no signal corresponding to cysteine sulfonic acid‐containing peptide could be observed in the mass spectrum. However, by addition of DAHC to CHCA, the peaks of cysteine sulfonic acid‐containing peptides were successfully observed, as well as when using 2,4,6‐trihydroxyacetophenone (THAP) and 2,6‐dihydroxyacetophenone with DAHC. In the DIOS mass spectra of these analytes, the use of DAHC also enhanced the peak intensity of the cysteine sulfonic acid‐containing peptides. On the basis of studies with these model peptides, tryptic digests of oxidized peroxiredoxin 6 were examined as a complex peptide mixture by MALDI and DIOS. In MALDI, the peaks of cysteine sulfonic acid‐containing peptides were observed when using THAP/DAHC as the matrix, but this was not so with CHCA. In DIOS, the signal from cysteine sulfonic acid‐containing peptides was suppressed; however, the use of DAHC significantly enhanced the signal intensity with an increase in the number of observed peptides and increased signal‐to‐noise ratio in the DIOS spectra. The results show that DAHC in the matrix or on the DIOS chip decreases discrimination and suppression effects in addition to suppressing alkali‐adduct ions, which leads to a beneficial effect on protonation of peptides containing cysteine sulfonic acid.

Differential expression of the four untranslated BDNF exons in the adult mouse brain
Authors: Malkovska Irena , Kernie Steven G. , Parada Luis F. 
Published: December 2005

AbstractBrain‐derived neurotrophic factor (BDNF) is a member of the neurotrophin family of secreted proteins and has important functions in the peripheral and central nervous systems (CNS). Its gene organization is complex, comprising four untranslated exons, each with an associated promoter. We have examined the expression of the four untranslated exons in direct comparison to one another and to the fifth BDNF coding exon by in situ hybridization. Other studies have examined untranslated exon expression in several brain regions in response to specific stimuli; however, this is the first detailed study to describe endogenous exon 1–4 expression throughout the adult mouse brain at baseline conditions. The differential expression of the four untranslated exons seen throughout the brain indicates a complex regulation of BDNF. © 2005 Wiley‐Liss, Inc.
Reorganization of CA3 area of the mouse hippocampus after pilocarpine induced temporal lobe epilepsy with special reference to the CA3‐septum pathway
Authors: Ma Dong Liang , Tang Yong Cheng , Chen Peng Min , Chia Shwn Chin , Jiang Feng Li , Burgunder Jean‐Marc , Lee Wei Ling , Tang Feng Ru 
Published: December 2005

AbstractWe showed that when CA3 pyramidal neurons in the caudal 80% of the dorsal hippocampus had almost disappeared completely, the efferent pathway of CA3 was rarely detectable. We used the mouse pilocarpine model of temporal lobe epilepsy (TLE), and injected iontophoretically the anterograde tracer phaseolus vulgaris leucoagglutinin (PHA‐L) into gliotic CA3, medial septum and the nucleus of diagonal band of Broca, median raphe, and lateral supramammillary nuclei, or the retrograde tracer cholera toxin B subunit (CTB) into gliotic CA3 area of hippocampus. In the afferent pathway, the number of neurons projecting to CA3 from medial septum and the nucleus of diagonal band of Broca, median raphe, and lateral supramammillary nuclei increased significantly. In the hippocampus, where CA3 pyramidal neurons were partially lost, calbindin, calretinin, parvalbumin immunopositive back‐projection neurons from CA1–CA3 area were observed. Sprouting of Schaffer collaterals with increased number of large boutons in both sides of CA1 area, particularly in the stratum pyramidale, was found. When CA3 pyramidal neurons in caudal 80% of the dorsal hippocampus have almost disappeared completely, surviving CA3 neurons in the rostral 20% of the dorsal hippocampus may play an important role in transmitting hyperactivity of granule cells to surviving CA1 neurons or to dorsal part of the lateral septum. We concluded that reorganization of CA3 area with its downstream or upstream nuclei may be involved in the occurrence of epilepsy. © 2005 Wiley‐Liss, Inc.

Construction of systems of differential equations of Okubo normal form with rigid monodromy
Authors: Yokoyama Toshiaki 
Published: December 2005

AbstractFor systems of differential equations of the form (xI n – T )dy /dx = Ay (systems of Okubo normal form), where A is an n × n constant matrix and T is an n × n constant diagonal matrix, two kinds of operations (extension and restriction) are defined. It is shown that every irreducible system of Okubo normal form of semi‐simple type whose monodromy representation is rigid is obtained from a rank 1 system of Okubo normal form by a finite iteration of the operations. Moreover, an algorithm to calculate the generators of monodromy groups for rigid systems of Okubo normal form is given. (© 2006 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
Formation and Detection of Clay Network Structure in Poly(propylene)/Layered Silicate Nanocomposites

Published: December 2005

AbstractSummary: The study of the structure and the rheological properties of poly(propylene) (PP)/montmorillonite (MMT)/maleinated PP (MAPP) composites strongly suggests that a silicate network may form under certain conditions. Network formation could not be proven unambiguously with the usual techniques, i.e., with TEM and by plotting the frequency dependence of viscoelastic properties. Cole‐Cole plots detect the network very sensitively. A certain number of silicate layers are needed to create a house‐of‐cards structure. A threshold concentration of MAPP exists in the investigated system, which depends on the silicate content.Cole‐Cole representation of the viscoelastic properties of PP/OMMT/MAPP nanocomposites.imageCole‐Cole representation of the viscoelastic properties of PP/OMMT/MAPP nanocomposites.
Electrospinning of Hyaluronic Acid (HA) and HA/Gelatin Blends

Published: December 2005

AbstractSummary: In the present study, electrospinning of hyaluronic acid (HA) and hyaluronic acid/gelatin (HA‐GE) blends in N,N‐dimethylformamide (DMF)/water‐mixed solvents have been investigated. When the volume ratio of DMF to water was in the range of 1.5–0.5, HA solutions could be electrospun into fibrous membranes successfully. The average diameter of HA fibers was about 200 nm. The HA‐GE composite nanofibrous membranes with varied HA/GE weight ratio in the range of 100/20–100/100 have also been successfully fabricated. The average diameter of HA‐GE fibers was in the range of 190–500 nm. The decrease in surface tension could promote fiber formation. Thus, an introduction of DMF that could decrease the surface tension distinctively, without significant change or increase in viscosity of the solution, could bypass the use of blowing‐assisted electrospinning. Our postulated picture is that the lower surface tension could help the ejection of stream with relatively high viscosity and reduce or prevent the droplet formation during the spinning process.HA/GE (100/80) nanofibrous membrane produced by electrospinning.imageHA/GE (100/80) nanofibrous membrane produced by electrospinning.
SCF Theory of a Polymer Brush Immersed into a Multi‐Component Solvent
Authors: Amoskov Victor M. , Birshtein Tatiana M. , Mercurieva Anna A. 
Published: December 2005

AbstractSummary: Self‐consistent field (SCF) theory is developed for a polymer brush immersed into a multi‐component solvent. Thermodynamics of the plane inhomogeneous brush is mainly determined by thermodynamics of the basic system, i.e., a homogeneous solution of a polymer dissolved in a multi‐component solvent that is in partial (or membrane) equilibrium with a bulk. Binary solvent with partially miscible components is in the focus of this investigation. The peculiarities of the brush are studied on the basis of the phase diagrams constructed for the basic system. Non‐trivial effects are demonstrated: microphase segregation of the brush and collapse of the brush under its filling with a good solvent in a pre‐binodal region of the bulk mixed solvent. Mathematical apparatus is developed and allows obtaining phase diagrams, density profiles, and other characteristics of the system under consideration.Polymer brush immersed into mixed solvent.magnified imagePolymer brush immersed into mixed solvent.
Prediction of Glass Transition Temperatures for Polystyrenes by a Four‐Descriptors QSPR Model
Authors: Yu Xinliang , Wang Xueye , Li Xiaobing , Gao Jinwei , Wang Hanlu 
Published: December 2005

AbstractSummary: A set of new molecular descriptors, RSC, SMC, DHB and MPE, which are obtained directly from polystyrenes monomer structures, are used to predict the Tg values of polystyrenes and generate a QSPR model by multiple linear stepwise regression analysis, with R = 0.959 and s = 15.20 K. Compared with the existing QSPR models, the proposed model requires only four descriptors, which can be obtained by simple calculation and makes it more valuable to predict the Tg values of polymers.

Hsp90 inhibitors: Small molecules that transform the Hsp90 protein folding machinery into a catalyst for protein degradation
Authors: Blagg Brian S. J. , Kerr Timothy D. 
Published: December 2005

AbstractThe 90 kDa heat shock proteins (Hsp90) are responsible for the conformational maturation of nascent polypeptides and the renaturation of denatured proteins. In transformed cells, numerous mutated and overexpressed proteins rely on the Hsp90 protein folding machinery for tumor progression. The Hsp90‐mediated protein folding process is dependent upon ATP, and when inhibitors of ATP are present, the Hsp90 machinery is unable to fold client proteins into their biologically active form, which results in the degradation of protein substrates via the ubiquitin‐proteasome pathway. Consequently, Hsp90 has evolved into a promising anti‐cancer target because multiple oncogenic proteins can be simultaneously degraded as a consequence of Hsp90 inhibition. This review serves to explain the Hsp90 protein folding process, the impact of Hsp90 inhibition, the identification of natural product inhibitors, and the development of rationally designed inhibitors of the Hsp90 protein folding machinery. © 2005 Wiley Periodicals, Inc.
Wideband internal folded planar monopole antenna for UMTS/WiMAX folder‐type mobile phone
Authors: Wong Kin‐Lu , Su Wei‐Cheng , Chang Fa‐Shian 
Published: December 2005

AbstractA simple folded planar metal‐plate monopole antenna suitable for operation as a wideband internal antenna for a folder‐type mobile phone is presented. The folder‐type mobile phone is modeled to comprise an upper ground plane and a lower ground plane, and the proposed antenna is employed at the hinge position between the upper and lower ground planes. The antenna has a compact structure and yet generates a wide operating bandwidth of about 4.8 GHz (from about 1.7 to 6.5 GHz), allowing it to easily cover UMTS and WiMAX operations. Details of the proposed antenna are described, and the experimental results of constructed prototypes are presented and discussed. The effects of the various lengths of the upper ground plane on the impedance matching of the antenna are also studied. © 2005 Wiley Periodicals, Inc.

Clock synchronization using a linear process model
Authors: Aweya James , Montuno Delfin Y. , Ouellette Michel , Felske Kent 
Published: December 2005

AbstractIn this paper, we present a clock synchronization scheme based on a simple linear process model which describes the behaviors of clocks at a transmitter and a receiver. In the clock synchronization scheme, a transmitter sends explicit time indications or timestamps to a receiver, which uses them to synchronize its local clock to that of the transmitter. Here, it is assumed that there is no common network clock available to the transmitter and the receiver and, instead, the receiver relies on locking its clock to the arrival of the timestamps sent by the transmitter. The clock synchronization algorithm used by the receiver is based on a weighted least‐squares criterion. Using this algorithm, the receiver observes and processes several consecutive clock samples (timestamps) to generate accurate timing signals. This algorithm is very efficient computationally, and requires the storage of only a small number of clock samples in order to generate accurate timing signals.

MAN@RCHISES: new added‐services architecture in automatic management networking
Authors: Nguyen Tuan Loc , Ouakil Laurent , Pujolle Guy , Jamalipour Abbas 
Published: December 2005

AbstractThe environment of the telecommunications service operators is particularly complex today with the integration of very diverse services coming from the Internet. This complexity arises from an integration between telecommunications and the Internet. The generalization of the Internet continues to grow unabated, especially with the rapid adoption of mobile and fixed wireless connecting a myriad of devices in homes and businesses. It allows us to have more and more services at low cost. In the future, anyone with any kind of device at any times will have options to access any service from anywhere. In fulfilling this requirement, more rapid and profitable methods of service creation and management must be examined. In this context, MAN@RCHISES, a network‐based application concept, is proposed in this paper. This concept results in the integration of the Internet service concept and the intelligence in networking concept of the telecommunications world. MAN@RCHISES is an architecture in which the applications and the services are not ported onto a pre‐existing network, but where the network itself grows out of the applications and the services that end user demands. The major objective of this article is to propose a new architecture for the adaptive and self‐organizing ambient aware applications. Copyright © 2006 John Wiley & Sons, Ltd.
On averaging of the non‐periodic conductivity coefficient using two‐scale extensions
Authors: Laptev Vsevolod , Belouettar Salim 
Published: December 2005

AbstractWe consider a second order elliptic equation with known rapidly oscillated coefficient. The equation appears to describe such problems as heat transfer in composite materials, flow in non‐homogeneous porous media as well as in many others. For the periodic coefficient the averaging procedure is well known. The non‐periodic case is still a challenging problem. We present a two‐scale extension approach and apply it on one numerical example in 2D. (© 2005 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
Modelling and Optimization of Cogeneration Plants
Authors: Lasch Peter , Büskens Christof , Knauer Matthias 
Published: December 2005

AbstractCogeneration plants have a long tradition in Germany and are used to transfrom a given energy into various destination energies, e.g. natural gas into mechanical, electrical and heat energy. In this paper a cogeneration plant composed of several components like gas turbines, waste heat boilers, steam turbines, etc, is modelled in steady state. The thermo‐dynamic behaviour of the plant is determined by a set of measured data, which is used to adopt the mathematical model to the real plant. By defining a suitable objective function incorporating e.g. emission trading, an appropriate NLP‐solver can be used to solve the generated model which includes several nonlinear constraints. Solutions for different environmental and business conditions are presented, to demonstrate the enormous potential of the proposed method for energy suppliers. (© 2005 WILEY‐VCH Verlag GmbH & Co.

Methods of Resolution for the Poisson Equation on the 3D Ball
Authors: Michel Dominik 
Published: December 2005

AbstractWithin the article at hand, we investigate the Poisson equation solved by an integral operator, originating from an ansatz by Greens functions. This connection between mass distributions and the gravitational force is essential to investigate, especially inside the Earth, where structures and phenomena are not sufficiently known and plumbable. Since the operator stated above does not solve the equation for all square‐integrable functions, the solution space will be decomposed by a multiscale analysis in terms of scaling functions. Classical Euclidean wavelet theory appears not to be the appropriate choice. Ansatz functions are chosen to be reflecting the rotational invariance of the ball. In these terms, the operator itself is finally decomposed and replaced by versions more manageable, revealing structural information about itself. (© 2005 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

AbstractThe car following model under discussion is a system of ordinary differential equations describing N cars moving around a circular road. We extend the stability analysis of the model in two directions: variable reaction time (depending on the headway) and an additional part describing the aggressive driving tendency. We study the global bifurcation dynamics and in particular its dependence on these two new ingredients. (© 2005 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
A Method for allowing Local Editing of Globally Optimized Splines
Authors: Tändl Martin , Kecskeméthy Andrés 
Published: December 2005

AbstractThe present work describes an algorithm for modifying spline curves in the neighborhood of an editing point while preserving global smoothness properties. Current spline algorithms have either a graphical editing mode in which the user edits local properties of the spline, or a globally optimizing mode, in which the spline coefficients are determined such that overall properties e. g. smoothness, distance to support points, or physical behavior are optimized. With globally optimized splines, editing parameters at one point causes their transmission through the whole spline. Hence, the user has the impression that it is not possible to change the shape of the spline without disturbing the overall behavior. This can be circumvented by forcing the trajectory of the globally optimized curve to lie in the close vicinity of the original curve far away from the edited point. The present work describes an algorithm for local editing of spline curves that are produced by a global optimizer. (© 2005 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
