An assessment of the EU growth forecasts under asymmetric preferences
Authors: Christodoulakis George A. , Mamatzakis Emmanuel C. 
Published: June 2008

AbstractEU Commission forecasts are used as a benchmark within the framework of the Stability and Growth Pact, aimed at providing a prudential view of economic outlook, especially for member states in an Excessive Deficit Procedure. Following Elliott et al. (2005), we assess whether there exist asymmetries in the loss preference of the Commission's GDP growth forecasts from 1969 to 2004. Our empirical evidence is robust across information sets and reveals that the loss preferences tend to show some variation in terms of asymmetry across member states. Given certain conditions concerning the time horizon of forecasts and the functional form of the loss preferences, the evidence further reveals that the Commission forecasting exercise could be subject to caveats. Copyright © 2008 John Wiley & Sons, Ltd.

Published: June 2008

AbstractBackgroundFine‐needle aspiration (FNA) or touch preparation with rapid assessment is a valuable diagnostic tool with a reported accuracy of diagnosis similar to intraoperative frozen section consultation. The Nigeria Christian Hospital partners with health care professionals from the United States to provide surgical care for rural residents of Aba, Nigeria. Frozen section diagnosis is impractical in this setting because of very limited resources. Therefore, intraoperative rapid assessment FNA or touch preparation to guide surgical management was performed on all mass lesions, and the results were evaluated.MethodsFNA was performed just before surgery using a 22‐gauge needle attached to a 10‐mL syringe and/or an intraoperative touch preparation was performed on biopsies of lesions that failed to yield cellular aspirates. Smears were prepared and stained with hematoxylin and eosin, and an immediate diagnosis was rendered. Tissue samples from the same resected/biopsied cases were fixed in 10% formalin and later transported to Vanderbilt University Medical Center Department of Pathology for processing. Cytologic and histologic correlations were then performed.Results and ConclusionsMore than 100 patients underwent surgery for head and/or neck masses during the 2‐week periods between November 2002 and November 2003. Of these patients, 98 had either preoperative FNA and/or intraoperative touch preparation performed. Twenty‐seven patients were male and 71 were female; the ages ranged from 2 months to 70 years. Sites sampled included the following: thyroid (n = 40); facial/jaw area (n = 19); parotid/submandibular gland (n = 13); scalp/skull region (n = 7); cervical lymph nodes (n = 5); neck (n = 5); other (n = 4); supraclavicular lymph nodes (n = 3); and oral cavity (n = 2). On cytologic analysis, there were 79 benign diagnoses, 17 malignant diagnoses, and 2 nondiagnostic samples. A benign versus malignant cytologic diagnosis was accurate in 97 of 98 cases. In conclusion, rapid assessment cytology was invaluable in the surgical treatment of many of the patients. © 2008 Wiley Periodicals, Inc. Head Neck, 2008

Published: June 2008

AbstractTat‐interacting protein 30 (TIP30), a transcriptional repressor for ERα‐mediated transcription, possesses several characteristics of a tumor suppressor in certain human and mouse cells. It is reported that deletion of TIP30 gene preferentially increases tumorigenesis in the female knockout mice. Here, we analyzed TIP30 gene expression in the databases of several DNA microarray studies of human prostate cancer and show that TIP30 is specifically overexpressed in metastatic prostate cancers. We demonstrate that TIP30 nuclear expression is associated with prostate cancer progression and metastasis by immunohistochemical analysis in primary and metastatic prostate cancers. Consistent with these data, we also show that knockdown of TIP30 expression, through use of a short hairpin RNA‐expressing plasmid, suppresses the cellular growth of PC3 and LNCaP prostate cancer cells. Ectopic overexpression of TIP30 stimulates metastatic potential of prostate cancer cells in an in vitro invasion assay, whereas knockdown of TIP30 inhibits the prostate cancer cells invasion. Finally, we demonstrate that ectopic overexpression of TIP30 enhances androgen receptor mediated transcription, whereas knockdown of TIP30 results in a decreased transcription activity. These data provide evidence that TIP30 plays a role in prostate cancer progression and that TIP30 overexpression may promote prostate cancer cell growth and metastasis. © 2008 Wiley‐Liss, Inc.
An ant colony pairwise alignment based on the dot plots
Authors: Chen Weiyang , Liao Bo , Zhu Wen , Liu Hao , Zeng Qingguang 
Published: June 2008

AbstractSequence alignment is one of the most important operations in bioinformatics. In this article, we introduced a new method for pairwise alignment. We associated the process of aligning with the plan by the modified dot plots. The next position will be selected by the number of pheromone and the matching score of the candidates. The presented algorithm can be used to find the best aligning result without calculating the scoring matrix. Superiority of the presented algorithm has been proved in several experiments. © 2008 Wiley Periodicals, Inc. J Comput Chem 2009
Improving the oxidation resistance of γ‐titanium aluminides by halogen treatment
Authors: Donchev A. , Schütze M. 
Published: June 2008

AbstractIntermetallic alloys based on TiAl are candidates for several structural high temperature applications but their oxidation resistance is limited to temperatures below 800 °C. In this paper the results of high temperature oxidation and creep tests will be presented and discussed. The treatment with halogens improves the oxidation resistance of these alloys up to 1050 °C. A thin protective Al2O3‐layer is formed after treatment with halogens instead of the mixed TiO2/Al2O3/TiN scale typically grown on these alloys. This alumina layer protects the component under isothermal and thermocyclic conditions. The protective effect is stable up to at least 8760 h. Creep tests of halogen treated materials at high temperatures showed no effect on the creep behaviour. Automotive turbocharger rotors were exposed at 1050 °C in air with and without fluorine‐treatment for demonstration of real parts.
The Role of Intermolecular Hydrogen Bonding on Thermal Properties of Maleimide–Isobutene Alternating Copolymers with Polar Groups
Authors: Omayu Akitoshi , Ueno Takako , Matsumoto Akikazu 
Published: June 2008

AbstractThermally stable copolymers with an alternating repeating structure, poly(RMI‐alt‐IB)s, were synthesized by radical copolymerization of N‐substituted maleimides containing a polar group with isobutene. The onset temperature of decomposition was higher than 300 °C and the glass‐transition temperature increased by the introduction of hydroxy and carboxy groups. IR spectroscopic analysis revealed the role of intermolecular hydrogen bonding on the thermal stability of the copolymers. It was also revealed that the amount of water absorbed into poly(RMI‐alt‐IB)s with a hydroxymethyl substituent was as high as 270% of the weight of the used polymer, while the introduction of a carboxy group resulted in lower water absorption properties.magnified image

Authors: Xu Xiaojing 
Published: June 2008

AbstractIn this paper, we consider local well‐posedness and ill‐posedness questions for the fractal Burgers equation. First, we obtain the well‐posedness result in the critical Sobolev space. We also present an unconditional uniqueness result. Second, we show the ill‐posedness from the point of view of the Picard iterations in the supercritical space.

Analysis of supply contracts with commitments and flexibility
Authors: Bassok Yehuda , Anupindi Ravi 
Published: June 2008

AbstractIn this article we address an important class of supply contracts called the Rolling Horizon Flexibility (RHF) contracts. Under such a contract, at the beginning of the horizon a buyer has to commit requirements for components for each period into the future. Usually, a supplier provides limited flexibility to the buyer to adjust the current order and future commitments in a rolling horizon manner. We present a general model for a buyer's procurement decision under RHF contracts. We propose two heuristics and derive a lower bound. Numerically, we demonstrate the effectiveness of the heuristics for both stationary and non‐stationary demands. We show that the heuristics are easy to compute, and hence, amenable to practical implementation. We also propose two measures for the order process that allow us to (a) evaluate the effectiveness of RHF contracts in restricting the variability in the orders, and (b) measure the accuracy of advance information vis‐a‐vis the actual orders. Numerically we demonstrate that the order process variability decreases significantly as flexibility decreases without a dramatic increase in expected costs. Our numerical studies provide several other managerial insights for the buyer; for example, we provide insights into how much flexibility is sufficient, the value of additional flexibility, the effect of flexibility on customer satisfaction (as measured by fill rate), etc. © 2008 Wiley Periodicals, Inc.

AC electric field‐assisted assembly and alignment of cellulose nanocrystals
Authors: Habibi Youssef , Heim Thomas , Douillard Roger 
Published: June 2008

AbstractIn this article, we describe an efficient physical electric‐field‐assisted method to study self‐assembly and orientation of cellulose nanocrystals. When applying an alternating voltage to a cellulose nanocrystals suspension deposited onto a thin gap of coplanar lithographically patterned metallic electrodes, a highly homogeneous orientation of cellulose nanocrystals is obtained. Parameters such as strength and frequency of the applied electric field and cellulose nanocrystals aspect ratios were studied to determine how they affect cellulose nanocrystals assembly and orientation. The prepared films were analyzed by atomic force microscopy, and the results suggest that the alignment of cellulose nanocrystals generated films is greatly influenced by the frequency and the strength of the applied electric field. The orientation of cellulose nanocrystals becomes more homogeneous with increasing electric field higher than 2000 V/cm with a frequency ranging between 104 and 106 Hz. © 2008 Wiley Periodicals, Inc.

Plant response to heavy metal toxicity: Comparative study between the hyperaccumulator Thlaspi caerulescens (ecotype Ganges) and nonaccumulator plants: Lettuce, radish, and alfalfa
Authors: Benzarti Saoussen , Mohri Shino , Ono Yoshiro 
Published: June 2008

AbstractThlaspi caerulescens (alpine pennycress) is one of the best‐known heavy metal (HM) hyperaccumulating plant species. It exhibits the ability to extract and accumulate various HM at extremely high concentrations. In this hydroponic study, the performance of T. caerulescens (ecotype Ganges) to accumulate Cd, Zn, and Cu was compared with that of three nonaccumulator plants: alfalfa (Medicago sativa), radish (Raphanus sativus), and lettuce (Lactuca sativa). Plants were exposed to the separately dissolved HM salts for 7 days at a wide range of increasing concentrations: 0 (control: 1/5 Hoagland nutrient solution), 0.1, 1, 10, 100, and 1000 μM. The comparative study combined chemical, physiological, and ecotoxicological assessments. Excessive concentrations of HM (100 and 1000 μM) affected plant growth, photosynthesis, and phytoaccumulation efficiency. Root exudation for all plant species was highly and significantly correlated to HM concentration in exposure solutions and proved its importance to counter effect toxicity. T. caerulescens resisted better the phytotoxic effects of Cd and Zn (at 1000 μM each), and translocated them significantly within tissues (366 and 1290 μg g−1, respectively). At the same HM level, T. caerulescens exhibited lower performances in accumulating Cu when compared with the rest of plant species, mainly alfalfa (298 μg g−1). Root elongation inhibition test confirmed the selective aptitude of T. caerulescens to better cope with Cd and Zn toxicities. MetPLATE bioassay showed greater sensitivity to HM toxicity with much lower EC50 values for β‐galactosidase activity in E. coli. Nevertheless, exaggerated HM concentrations coupled with relatively short exposure time did not allow for an efficient metal phytoextraction thus a significant reduction of ecotoxicity. © 2008 Wiley Periodicals, Inc.

Published: June 2008

Abstract and SummaryUpward trending world population and increasing costs for traditional food proteins provide many incentives for utilization of oilseed proteins directly in human diets. Cotton, as one of the world's major oilseed crops, represents a potential source of food protein. Acceptability of oilseed protein products in terms of functional properties in food systems and nutritional value will largely determine the extent of their utilization by the food industry. Liquid cyclone process cottonseed flour, defatted glandless cottonseed flour, storage protein isolates, and cottonseed whey proteins have been evaluated by various functionality tests and in a number of food systems. The cottonseed flours have been subjected to processing by extrusion texturization. Human feeding studies have also been conducted. Results indicate a good potential for use of cottonseed protein products in a variety of food systems.
Peanut protein: A versatile food ingredient
Authors: Ayres J. L. , Davenport B. L. 
Published: June 2008

AbstractPeanut flour has been evaluated for use in a variety of food products as a replacement for animal source proteins. In breakfast cereals and snack foods, peanut flour blends well with cereal flours to yield products with excellent flavor, texture, and color. Peanut flour can be used to produce textured vegetable protein or can be used directly in ground meats to provide good moisture and fat binding characteristics. In bakery products, peanut flour can be used at levels up to 20% to provide protein supplementation without the astringent flavor of other oilseed flours.

Surface activity of sucrose palmitates
Authors: Fisher G. S. , Zeringue H. J. , Feuge R. O. 
Published: June 2008

Abstract and SummaryInterfacial tension data are presented for cotton‐seed oil‐water and paraffin oil‐water systems containing purified sucrose palmitates of different degrees of acylation. Both the monopalmitates and diplamitates effectively reduced interfacial tension. To be effective, the monoesters had to be dissolved in water, the diesters in oil. Although nearly inactive alone, sucrose tripalmitate was active in mixtures with the mono‐and dipalmitates. Efficiencies of the sucrose palmitates were also excellent. In general, mixtures of sucrose palmitates were as effective as the most active component. When dissolved in water, the efficiency of sucrose palmitate mixtures was proportional to the monoester content, but when dissolved in oil mono‐, di‐, and triesters contributed to the efficiency.

Published: June 2008

ObjectivesWe have developed an animal model to investigate the feasibility of using a digital radiography picture archive and communication system (PACS) to identify fish bones.Subjects and MethodsBones from 21 species of freshwater and seawater fish were placed in the upper esophagus of a test pig. Digital radiographic images of the lateral neck were taken (60 kV, 200 mA, and 20 ms, 100 cm in distance). The images were interpreted by three radiologists. The X2 test, Kendall's coefficient of concordance, and the logistic regression model were applied for statistical analyses.ResultsMilkfish had the lowest visibility (33.3%) in PACS. There was a significant variation in the ratings of visibility among three radiologists (P < 0.01, Kendall's coefficient 0.75). Seawater vs freshwater category, bone length, and radiologist were significant factors that affected visibility.ConclusionThe sensitivity is 0.89. Images from seawater fish with long bones have better visibility. PACS is feasible in diagnosing upper esophagus fish bones, but the physician's knowledge of local varieties of fish prior to image study is equally important.

ObjectiveTo describe the interventions required for successful airway management in children with Pierre Robin Sequence (PRS).Study DesignCase series.Subjects and MethodsThe records of both a cleft and craniofacial clinic and a pediatric otolaryngology clinic were searched, and all children with PRS were identified. Data concerning feeding interventions, airway interventions, and comorbid conditions were extracted.ResultsSeventy‐four cases of PRS were identified. Thirty eight of the 74 children required airway intervention other than prone positioning. Fourteen of these 38 were managed nonsurgically with nasopharyngeal airway and/or short‐term endotracheal intubation, whereas the remaining 24 required surgical intervention. Eighteen of the 24 underwent distraction osteogenesis of the mandible, one underwent tracheostomy, and five underwent tracheostomy followed by eventual distraction.ConclusionIn our series, over 50 percent of children with PRS required an airway intervention. These were both nonsurgical and surgical. As otolaryngologists, we must be prepared for the challenges children with PRS may present and the interventions that may be necessary to successfully manage these difficult airways.
Metastatic rectal adenocarcinoma in the external auditory canal

Published: June 2008

AbstractObjectives:To present a rare case of rectal adenocarcinoma metastasising to the external auditory canal, in a patient in whom computed tomography staging of the abdomen, chest and pelvis was clear for metastatic disease.Methods:Case report and review of the literature.Conclusions:Metastatic tumours to the external auditory canal are rare, with rectal adenocarcinoma being one of the rarest. However, it is important that the external auditory canal is regarded as a potential site for metastasis, even when computed tomography staging is clear. Metastatic tumour should be included in the differential diagnosis of a patient presenting with an ear mass.
Dispersion relations for electromagnetic waves in a dense magnetized plasma
Authors: SHUKLA P. K. , STENFLO L. 
Published: June 2008

AbstractDispersion relations for elliptically polarized extraordinary as well as linearly polarized ordinary electromagnetic waves propagating across an external magnetic field in a dense magnetoplasma are derived, taking into account the combined effects of the quantum electrodynamical (QED) field, as well as the quantum forces associated with the Bohm potential and the magnetization energy of the electrons due to the electron-1/2 spin effect. The QED (vacuum polarization) effects, which contribute to the nonlinear electron current density, modify the refractive index. Our results concern the propagation characteristics of perpendicularly propagating high-frequency electromagnetic waves in dense astrophysical objects (e.g. neutron stars and magnetars), as well as the next-generation intense laser–solid density plasma interaction experiments and quantum free-electron laser schemes.
