Published: April 2008

AbstractObjective:Evaluate the clinical characteristics of feeding difficulties in 30 community (i.e., nonreferred) infants in the first 2 years of life, and their correlation with mother/child interactions.Method:An “in depth” mental health evaluation of feeding difficulties, and the psychosocial functioning of the child in other areas. The mother‐infant relationship and the feeding interactions were also assessed.Results:Four “groups” were identified. (1) Young infant with difficulties in regulating states and sucking. (2) Older infant with difficulties in self‐regulation, focusing, hyper‐alert, and with aversion to feeding. (3) Older infants hypersensitive to stimuli (taste, odor) and with difficulties in chewing. (4) Group of with varied and unique feeding problems (pica, rumination).Conclusion:Feeding problems tend to have patterns according to the age of the baby in a nonreferred sample. They are not associated with an altered parent‐infant relationship nor poor feeding technique. Parents often adapt successfully to the uniqueness of the baby to maintain weight gain. © 2008 by Wiley Periodicals, Inc. Int J Eat Disord 2008
Season of birth bias in eating disorders—Fact or fiction?
Authors: Winje Eirin , Willoughby Kate , Lask Bryan 
Published: April 2008

AbstractObjective:A season of birth (SoB) bias is said to be present if the SoB pattern for a particular group varies from the pattern within the normal population. Significant biases have been found for several disorders including eating disorders (EDs). This article critically reviews the existing literature on SoB in ED in order to inform future hypothesis‐based research.Method:A literature search identified 12 papers investigating SoB in ED.Results:Despite methodological differences, the studies consistently show a SoB bias for anorexia nervosa (AN) in the spring months, in both the northern and southern Hemispheres. This is especially strong for early‐onset and restrictive subtype of AN.Conclusion:These findings suggest that SoB is a risk factor for AN. However, none of the studies have been methodologically satisfactory. Future research needs to overcome numerous methodological challenges and to explore specific hypotheses to explain this bias. © 2008 by Wiley Periodicals, Inc. Int J Eat Disord 2008
Ultrasonic reflectivity computed tomography with small number of transmitter/receiver transducers for carotid diagnosis
Authors: Yamada Akira , Goto Yasuyuki 
Published: April 2008

AbstractWe developed an ultrasound reflectivity computed tomography (CT) system with only a small number of transmitter/receiver transducers for carotid diagnosis. To this end, a ring array system with eight element transducers was fabricated with center frequency 10 MHz. The present CT technique assures the image with high resolution on the order of 0.1 mm over the entire imaging region. In addition, the reduction of the number of transducer element enables fast data acquisition and lower cost hardware system. With appropriate combinations of the dual and/or separate transmitter and receiver pairs, 21 backscattering projection data were observed. To comply with the ill‐posed inverse problem due to the lack of angular view data, the conjugate gradient method was applied for the solution of the matrix observation equation. Both experiment and simulation examinations were made using the cylindrical shell object as a carotid phantom. As a result, it is demonstrated that the image with greater resolution compared with the conventional B‐mode method can be obtained by using only eight element transducers. © 2008 Wiley Periodicals, Inc.

Design of controller switching strategy for reusable launch vehicle with elevon jamming failure
Authors: Komatsu Hayato , Suzuki Tatsuya , Okuma Shigeru 
Published: April 2008

AbstractWhen a reusable launch vehicle (RLV) returns to earth, it flies just by gliding without thrust. In this phase, one of the most likely and important faults to occur in the airframe is a jamming of the elevon. To tolerate this failure, the flight control system must keep stability and performance during such a failure. One of the effective ways to overcome this problem is to switch the controllers based on the information of the detected failure in the plant. Generally speaking, the controller must have integrators so as to yield the zero steady‐state error for the controlled output even if there exist some perturbations in the plant dynamics. In this paper, the design of controller switching scenario is addressed especially focusing on the decision of the controller state at the instant of switching the controllers with integrator. Then, the proposed switching scenario is applied to the control of ALFLEX (Automatic Landing FLight EXperiment), which is the automatic landing experimental vehicle being developed for RLV, considering the occurrence of the jamming fault. Some simulations are shown to verify the usefulness of the proposed idea. © 2008 Wiley Periodicals, Inc.

Published: April 2008

AbstractAn advanced method of analysis for grid‐connected PV systems is developed in this research. To investigate the issues which may arise in the clustered PV systems, a “Demonstration Project on Clustered PV Systems” was initiated in December 2002 in Oota, Japan, involving the installation of more than 500 residential PV systems in the demonstrative research area, and the development of battery‐integrated PV systems to avoid restrictions on output power due to the raising of the grid voltage. The annual performance of commercial PV systems without battery was analyzed and a performance ratio of 80% on average was found to have been achieved. Overvoltage of power distribution lines and snow are two major factors capable of causing very low performance ratio on a daily basis. The effects of batteries have also been analyzed, and the results indicate that there will be some reduction of energy losses due to the grid voltage, but the PCS efficiency will be at least 8% worse than that of commercial PV systems. It was also found that nonoptimized battery operation sometimes results in a fully charged situation at noontime and maximum reverse power flow may not be minimized in this situation. © 2008 Wiley Periodicals, Inc.

AbstractThe synthesis of α/β‐L‐fucosylated cysteamine, 3‐thiopropionic acid, and 3‐thioacetic acid derivatives as building blocks for the preparation of S‐neofucopeptides is shown. These compounds were used in the synthesis of new thiofucosides derivatives (8α, 9α, 9β, 10α, 22α, 22β, 24α, 26α) that show affinity towards E‐ and P‐selectins. They constitute a new series of hydrolytically stable and low‐molecular‐weight mimetics of the natural SLex tetrasaccharide. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2008)
Direct Electrochemistry of Cytochrome c on a Silica Sol‐Gel Film Modified Electrode
Authors: Xu Jun‐Sheng , Zhao Guang‐Chao 
Published: April 2008

AbstractDilute silica sol‐gel was simply dropped on the surface of a basal plane graphite electrode (BPGE) to form a silica sol‐gel film modified electrode. Direct electrochemical response of cytochrome c (Cyt c) on the modified electrode was observed by cyclic voltammetry (CV). The results suggested that Cyt c could be tightly adsorbed on the surface of the silica sol‐gel film modified electrode. A couple of well‐defined and nearly reversible redox peaks can be observed in a phosphate buffer solution (pH 7.0), which anodic and cathodic peak potentials were at −0.243 and −0.306 V (vs. Ag/AgCl), respectively. Cyt c adsorbed on the surface of silica sol‐gel film shows a remarkable electrocatalytic activity for the reduction of oxygen. Based on these, a third‐generation biosensor could be constructed to detect the concentration of oxygen in aqueous solution.

Published: April 2008

AbstractProtein electrochemistry affords a direct method to study the biological electron transfer processes. However, supplying a biocompatible environment to maintain the native state of protein is all‐important and challengeable. Here, we chose vaterite, one of the crystalline polymorphs of calcium carbonate, with highly porous nature and large specific surface area, which was doped with phospholipids, as the matrix to immobilize horseradish peroxidase (HRP). The integrity of HRP was kept during the simple immobilization procedure. By virtue of this organic/inorganic complex matrix, the direct electrochemistry of HRP was realized, and the activity of HRP for catalyzing reduction of O2 and H2O2 was preserved.
Spatio‐temporal statistical modelling of significant wave height
Authors: Baxevani A. , Caires S. , Rychlik I. 
Published: April 2008

AbstractIn this paper, we construct a homogeneous spatio‐temporal model to describe the variability of significant wave height over small regions of the sea and over short periods of time. Then, the model is extended to a non‐homogeneous one that is valid over larger areas of the sea and for time periods of up to 10 h. To validate the proposed model, we reconstruct the significant wave height surface under different scenarios and then compare it to satellite measurements and the C‐ERA‐40 field.

Confidence interval for random‐effects calibration curves with left‐censored data
Authors: Aryal Subhash , Bhaumik Dulal K. , Santra Sourav , Gibbons Robert D. 
Published: April 2008

AbstractThe presence of left censoring in environmental and engineering applications complicates tests of hypotheses and interval estimation. First, we construct a confidence interval (CI) for a true concentration using nonlinear mixed‐effects regression models for analysis of interlaboratory calibration data with left censoring. Next, we impute the unobserved left‐censored data with randomly simulated value. Finally, we compute the coverage probability via simulation and show that our methodology achieves the nominal level. We illustrate our methodology with a real‐life example. Copyright © 2008 John Wiley & Sons, Ltd.
Model clustering and its application to water quality monitoring
Authors: Zhu Rong , El‐Shaarawi Abdel H. 
Published: April 2008

AbstractThe classification of objects into groups where the objects within a group share a set of common traits is important in many areas of applications and particularly in environmental pollution studies. Consider the situation where variables are measured on different occasions for each of K objects, and the objective is to classify these objects into groups according to some common characteristics. The procedure introduced in this paper consists of two aspects: model fitting and clustering. The model fitting selects a family of models which is appropriate for the structure and nature of the available measurements, and then is performed for both individual and pooled datasets. The clustering starts with K models that represent the K objects and thus the similarity of the objects reduces to the similarity of their models. Since the models are members of the same family, the models similarity is defined as the equality of their parameters of interest. Here, we partition the parameter vector into two sub‐vectors corresponding to the interested parameters and ancillary parameters. The clustering will group together objects that have common interested parameters while allowing the ancillary parameters to be object specifics. The p‐value associated with the proposed model linking test is used as the similarity measure. Several grouping strategies are proposed like cluster peeling, pairwise combining, as well as a speeding technique called splitting‐and‐binding. A small simulation study is used to demonstrate the utility of the method. The paper concludes by presenting an environmental application where the interest is to classify E. coli bacteria according to their responses to antibiotic treatments. The data were collected bi‐weekly at several locations within three Canadian watersheds during 2005. Metric closeness in parameter space used by conventional method and likelihood closeness in model space employed by model clustering are discussed in this application.

Residual relief separation: digital elevation model enhancement for geomorphological mapping
Authors: Hiller J. K. , Smith M. 
Published: April 2008

AbstractGeomorphologically mapped data form a primary set of observations that can be used to infer former environmental conditions. Thus, objective and consistent mapping of landforms from remotely sensed data (e.g. satellite imagery, digital elevation models (DEMs)) is paramount for reconstructing palaeoenvironments.This paper proposes a technique, ‘residual relief separation’, to enhance landforms in DEMs prior to visualization and digital mapping. This is applied to a ∼600 km2 region surrounding Lough Gara, Ireland, where drumlins (∼200 m wide) overlie a regional relief of hills (∼10 km wide). Here, residual relief separation uses this difference in width‐scale. Regional relief is approximated by a 1 km wide median filter, then subtracted to leave the drumlins in a ‘residual’ topography. In a second step, the residual relief is normalized to allow for amplitude variations in the drumlins across the area (∼5–40 m high). Finally, visualization uses a simple black‐to‐white colour scale for height.Although not numerically outperforming other visualization techniques, this method performs equally well, and as the data are not ‘illuminated’ there is no azimuthal bias. Additional benefits include the relatively simple calculation, intuitive visual comprehension, no emphasis of noise, and the possibility of using any desired visualization technique after the landscape has been topographically manipulated.

Variable‐length channel coding with noisy feedback
Authors: Draper Stark C. , Sahai Anant 
Published: April 2008

AbstractIt is known that perfect noiseless feedback can be used to improve the reliability of communication systems. We show how to make those gains robust to noise on the feedback link. We focus on feedback links that are themselves discrete memoryless channels. We demonstrate that Forney's erasure‐decoding exponent is achievable given any positive‐capacity feedback channel. We also demonstrate that as the desired rate of communication approaches the capacity of the forward channel, the Burnashev upper bound on the reliability function is achievable given any positive‐capacity noisy feedback channel. Finally, we demonstrate that our scheme dominates the erasure‐decoding exponent at all rates and, for instance, at zero rate can achieve up to three‐quarters of Burnashev's zero‐rate reliability. This implies that in a shared medium, to maximise the reliability function some degrees of freedom should be allocated to feedback. Copyright © 2008 John Wiley & Sons, Ltd.
On the capacity of interference channels with one cooperating transmitter
Authors: Marić Ivana , Goldsmith Andrea , Kramer Gerhard , Shamai (Shitz) Shlomo 
Published: April 2008

AbstractInner and outer bounds are established on the capacity region of two‐sender, two‐receiver interference channels (IC) where one transmitter knows both messages. The transmitter with this extra message knowledge is referred to as being cognitive. The inner bound is based on strategies that generalise prior work, and includes rate‐splitting, Gel'fand‐Pinsker (GP) coding and cooperative transmission. A general outer bound is based on the Nair‐El Gamal outer bound for broadcast channels (BCs). A simpler bound is presented for the case in which one of the decoders can decode both messages. The bounds are evaluated and compared for Gaussian channels. Copyright © 2008 John Wiley & Sons, Ltd.
Are human faces and voices ornaments signaling common underlying cues to mate value?
Authors: Feinberg David R. 
Published: April 2008

AbstractIn our daily lives, we constantly interact with people. We maintain relationships with families and friends. We collaborate with colleagues. We seek passion with our lovers and avoid conflicts with our enemies. How we divide the world into these and many other categories of people is initially guided by our first impressions of how they look and sound. Many times we are surprised when we hear someone on the phone whom we have not yet met face‐to face; they sound different from what we imagined. There are, however, many things that we are not surprised about in such situations. People are accurate at identifying sex, health, emotions, and age by both voices and faces.3–12 There is good evidence that many seemingly disparate ornaments such as body and face,13 body and voice,14–16 and face and odor19 may convey either backup signals of the same underlying quality20,21 or convey signals of different underlying qualities that are used in conjunction to provide a more robust view of the organism's overall fitness.22,23 Is this also true of face and voices?Until recently, little attention has been given to the idea that people's faces and voices might both signal the same underlying qualities related to hormone levels, and that we might use these hormonal fitness markers to provide a better picture of the signaler's overall mate value.20,21,24 In this paper I first argue that aspects of voices and faces can be used as markers of hormonal status. Second, I argue that both vocal and facial features associated with hormonal status are used by people to assess mate quality.
Primary mediastinal large cell lymphoma (PMBL): frontline treatment with autologous stem cell transplantation (ASCT). The GEL‐TAMO experience

AbstractGiven the excellent results obtained with present new induction regimens in PMBL, the role of frontline ASCT is controversial. We present 71 patients with PMBL receiving induction chemotherapy, followed by ASCT as frontline therapy from the GEL‐TAMO registry. Most patients presented with high‐risk clinical features. At transplant, 49% of patients were in CR, 32% in PR and 18% failed induction therapy; 53% received radiotherapy. After the transplant 75% of patients achieved CR. With a median follow‐up of 52.5 months, the OS, PFS and DFS at 4 years from diagnosis were, respectively, 84%, 81% and 81% for the first CR patients and 49%, 42% and 82% for the induction failure (PR and refractory) patients. Disease progression was the main cause of death (79%). By multivariate survival analysis the tumour score, refractory disease at transplant and radiotherapy were independent variables associated with OS and PFS. Our experience, with a prolonged follow‐up, shows that patients with PMBL presenting at diagnosis with high‐risk features or PR response to induction therapy have an encouraging survival with frontline ASCT. However, patients who received the transplant after failing the induction regimen have a very poor prognosis and should be tested with other innovative approaches. Finally, only a randomized trial could prove the value of ASCT as frontline therapy and also must be considered that addition to Rituximab to induction treatments could make ASCT unnecessary.

Solution of radiative transfer in a one‐dimensional anisotropic scattering media with different boundary conditions using the DRESOR method
Authors: Huang Zhi‐Feng , Cheng Qiang , He Cheng , Zhou Huai‐Chun 
Published: April 2008

AbstractThe DRESOR method was applied to analyze the radiative transfer process in anisotropic scattering media with different boundary conditions in this paper. The method was validated by the integral formulation of the radiative transfer equation at first. Some variation regulations about the emissivity were obtained by extensive numerical simulations. When the optical thickness of the media became very large, the emissivity converged to a constant value. The converged emissivity in the forward scattering medium was the largest and that for the backward scattering medium was the smallest. Also the converged emissivity was associated with the scattering albedo of the media. The greater the scattering albedo was, the smaller the converged emissivity was. When the scattering albedo decreased to zero the converged emissivity reached the blackbody emissivity at the same temperature. Furthermore, different boundary conditions were considered. The results showed that if the temperature of the medium and the boundary was equal, the intensity at boundary was the same as that for the blackbody emission at the same temperature, whether the boundary reflectivity was 1.0 or not. When the temperature of the boundary was lower than that of the medium, the boundary emissivity can reach 1.0 only if ρ=1.0. Finally, the radiation flux was studied with different phase functions and different boundary conditions. © 2008 Wiley Periodicals, Inc.
