An analytical approach to the performance evaluation of the balanced gamma switch under multicast traffic
Authors: Li Cheng , Venkatesan R. , M. Heys Howard 
Published: August 2006

AbstractThis paper presents the performance evaluation of a new cell‐based multicast switch for broadband communications. Using distributed control and a modular design, the balanced gamma (BG) switch features high performance for unicast, multicast and combined traffic under both random and bursty conditions. Although it has buffers on input and output ports, the multicast BG switch follows predominantly an output‐buffered architecture. The performance is evaluated under uniform and non‐uniform traffic conditions in terms of cell loss ratio and cell delay. An analytical model is presented to analyse the performance of the multicast BG switch under multicast random traffic and used to verify simulation results. The delay performance under multicast bursty traffic is compared with those from an ideal pure output‐buffered multicast switch to demonstrate how close its performance is to that of the ideal but impractical switch. Performance comparisons with other published switches are also studied through simulation for non‐uniform and bursty traffic. It is shown that the multicast BG switch achieves a performance close to that of the ideal switch while keeping hardware complexity reasonable. Copyright © 2006 John Wiley & Sons, Ltd.
Static and dynamic body image in bulimia nervosa: Mental representation of body dimensions and biological motion patterns
Authors: Vocks Silja , Legenbauer Tanja , Rüddel Heinz , Troje Nikolaus F. 
Published: August 2006

AbstractObjective:The aim of the present study was to find out whether in bulimia nervosa the perceptual component of a disturbed body image is restricted to the overestimation of one's own body dimensions (static body image) or can be extended to a misperception of one's own motion patterns (dynamic body image).Method:Participants with bulimia nervosa (n = 30) and normal controls (n = 55) estimated their body dimensions by means of a photo distortion technique and their walking patterns using a biological motion distortion device.Results:Not only did participants with bulimia nervosa overestimate their own body dimensions, but also they perceived their own motion patterns corresponding to a higher BMI than did controls. Static body image was correlated with shape/weight concerns and drive for thinness, whereas dynamic body image was associated with social insecurity and body image avoidance.Conclusion:In bulimia nervosa, body image disturbances can be extended to a dynamic component. © 2006 by Wiley Periodicals, Inc.

National identification, type and specificity of comparison and their effects on descriptions of national character
Authors: Nigbur Dennis , Cinnirella Marco 
Published: August 2006

AbstractStudies conducted in Britain (n = 88) and Germany (n = 128) used a questionnaire with an experimental manipulation to examine the effects of national identification, type of comparison (intergroup or temporal) and specificity of comparison (specific or non‐specific) on trait descriptions of national identity. Both differentiation between the subject and object of comparison and the absolute stereotype of the national ingroup (i.e. the national autostereotype) were measured. Regression analyses found that high identification was associated with greater ingroup bias and an overall more positive autostereotype; that specific temporal comparison with a shameful past (slavery for the British and the Nazi era for the German sample) predicted greater differentiation from the present than non‐specific comparisons with ‘the past’ in general; and that specific comparisons with the Americans or a shameful history precipitated greater differentiation and (in the British sample) a departure of the autostereotype from a control condition that entailed no comparison. We argue that our approach can contribute to a more holistic social identity analysis of nationality. Future research should distinguish the effects of context from those of identification, show an awareness of the potential differences between specific and non‐specific comparisons, and examine a greater variety of temporal comparison targets.

Group domination and inequality in context: evidence for the unstable meanings of social dominance and authoritarianism
Authors: Lehmiller Justin J. , Schmitt Michael T. 
Published: August 2006

AbstractBoth social dominance orientation (SDO) and right‐wing authoritarianism (RWA) are assumed to be general and relatively stable psychological orientations that individuals ‘carry with them’ from context to context, influencing responses to salient forms of intergroup inequality and domination. In two experimental studies we tested the relative stability of SDO (Studies 1 and 2) and RWA (Study 1). That is, we examined whether people who score relatively high on SDO/RWA in one context tend to support intergroup hierarchy and domination in other contexts. To do so, we manipulated the salience of different intergroup relationships before measuring SDO and RWA, and then observed the associations among these constructs and attitudes toward specific intergroup relationships and legitimizing ideologies (support for war, conservatism, heterosexism, and religious fundamentalism). Contrary to the assumption of relative stability, the extent to which SDO and RWA were related to these specific attitudes and ideologies varied markedly depending on the experimental context. These results highlight the contextual basis and meaning of individuals' expressed support for group‐based dominance. Copyright © 2006 John Wiley & Sons, Ltd.
Markedly different effects of hyaluronic acid and chondroitin sulfate‐A on the differentiation of human articular chondrocytes in micromass and 3‐D honeycomb rotation cultures
Authors: Banu Nasreen , Tsuchiya Toshie 
Published: August 2006

AbstractA source of morphologically and functionally available human cartilagenous tissue for implantation is required in the field of tissue engineering. To achieve this goal, we evaluated the effects of hyaluronic acid (HA‐810 and 1680 kDa), and chondroitin sulfate (CS‐A 16 and C‐34 kDa) on human articular chondrocytes (HC) in micromass and rotation culture conditions. Cell proliferation was increased by CS‐A 16 kDa under micromass and rotation cultures, while cell differentiation was increased under rotation but not micromass conditions. Proliferation and differentiation due to CS‐C 34 kDa were very similar to the control under both culture conditions. With HA, cell proliferation was increased depending on the molecular weight under micromass and rotation conditions. In contrast, chondrocyte differentiation was enhanced under rotation conditions, but decreased under micromass conditions depending on the molecular weight of HA. In both culture conditions, aggrecan gene was continuously expressed. However, the collagen type II gene was more weakly expressed in rotation than the micromass culture conditions. Thus, the chemical structures of polysaccharides, and the culture condition, rotation or micromass, caused differences in chondrogenesis. © 2006 Wiley Periodicals, Inc. J Biomed Mater Res, 2007
The interaction of human bone marrow cells with nanotopographical features in three dimensional constructs

Published: August 2006

AbstractUntil now, nanotopography has been considered in 2D construct designs. This has been due to fabrication limitations with traditional lithographic processes relying on the ability to focus radiation that will expose a radiation sensitive resist (e.g. photolithography and electron beam lithography). More recently, alternative methods that offer rapid and cheap nanofabrication have been developed; such methods include polymer demixing and colloidal lithography. Polymer demixing in 2D has relied on spin casting of polymer blends—such as polystyrene and polybromostyrene in a solvent such as toluene. As the solvent evaporates, the polymers phase separate and form nanoislands. In this study, the polymer blend solution has been blown through fine tubes and allowed to demix, thus providing 3D constructs for cell biology. The ability to fabricate in tubes may be useful in many applications, for example stents, conduits, and bone repair (when considering structures such as Haversian tubes and Volkmann's canals). As proof of concept, human osteoprogenitor cells have been used to test the cell response to the nanopatterned tubes. The results show that nanofeatures of size X, diameter Y, and spacing Z decrease cell spreading, reduce cytoskeletal organization, and increase endocytotic activity within the cells. © 2006 Wiley Periodicals, Inc.

Hardness, elasticity, and ultrastructure of bonded sound and caries‐affected primary tooth dentin
Authors: Hosoya Y. , Tay F. R. 
Published: August 2006

AbstractBiomechanical properties of bonded dentin are important factors for resin restoration. We evaluated the hardness and elastic modulus of bonded sound and caries‐affected primary tooth dentin using a one‐step adhesive system, and observed the microstructure of the bonded interface. Six sound and six carious primary teeth were used. For sound teeth, flat occlusal dentin surfaces were prepared with a water‐cooled high‐speed diamond bur. For carious teeth, infected dentin was stained with a caries detector and removed with a water‐cooled low‐speed round steel bur and hand instruments. The prepared dentin was bonded with One‐Up Bond F Plus (Tokuyama Dental Co., Tokyo, Japan). The resin–dentin interface and dentin beneath the interface were measured with a nano‐indentation tester and observed with SEM and TEM. For both the carious and sound teeth, there was no significant difference between the hardness of the interfacial dentin and dentin 10–80 μm beneath the interface. However, the Young's modulus of the interfacial dentin was significantly lower than the dentin 40–80 μm (carious teeth) or 50–80 μm (sound teeth) beneath the interface. Both the hardness and Young's modulus of the interfacial dentin were not significantly different between the carious and sound teeth. Compared to the sound dentin, the hybrid layer on the caries‐affected dentin was thicker and exhibited more complicated morphologic features. The thickness of the hybrid layers was generally less than 1 μm. © 2006 Wiley Periodicals, Inc. J Biomed Mater Res Part B: Appl Biomater, 2006
Sorption kinetics of ethanol/water solution by dimethacrylate‐based dental resins and resin composites
Authors: Sideridou Irini D. , Achilias Dimitris S. , Karabela Maria M. 
Published: August 2006

AbstractIn the present investigation the sorption–desorption kinetics of 75 vol % ethanol/water solution by dimethacrylate‐based dental resins and resin composites was studied in detail. The resins examined were made by light‐curing of bisphenol A glycol dimethacrylate (Bis‐GMA), triethylene glycol dimethacrylate (TEGDMA), urethane dimethacrylate (UDMA), bisphenol A ethoxylated dimethacrylate (Bis‐EMA), and mixtures of these monomers. The resin composites were prepared from two commercial light‐cured restorative materials (Z100 MP and Filtek Z250), the resin matrix of which is based on copolymers of the above‐mentioned monomers. Ethanol/water sorption/desorption was examined in both equilibrium and dynamic conditions in two adjacent sorption–desorption cycles. For all the materials studied, it was found that the amount of ethanol/water sorbed or desorbed was always larger than the corresponding one reported in literature in case of water immersion. It was also observed that the chemical structure of the monomers used for the preparation of the resins directly affects the amount of solvent sorbed or desorbed, as well as sorption kinetics, while desorption rate was nearly unaffected. In the case of composites studied, it seems that the sorption/desorption process is not influenced much by the presence of filler. Furthermore, diffusion coefficients calculated for the resins were larger than those of the composites and were always higher during desorption than during sorption. Finally, an interesting finding concerning the rate of ethanol/water sorption was that all resins and composites followed Fickian diffusion kinetics during almost the whole sorption curve; however, during desorption the experimental data were overestimated by the theoretical model. Instead, it was found that a dual diffusion–relaxation model was able to accurately predict experimental data during the whole desorption curve. Kinetic relaxation parameters, together with diffusion coefficients, are reported for all resins and composites. © 2006 Wiley Periodicals, Inc. J Biomed Mater Res Part B: Appl Biomater, 2006

Sensitivity of CFP/YFP and GFP/mCherry pairs to donor photobleaching on FRET determination by fluorescence lifetime imaging microscopy in living cells

Published: August 2006

AbstractFluorescent protein‐based FRET is a powerful method for visualizing protein–protein interactions and biochemical reactions in living cells. It can be difficult, however, to avoid photobleaching when observing fluorescent cells under the microscope, especially those expressing CFP. We compared the sensitivity of two protein‐based FRET pairs to light‐induced fluorescence changes in the donor, on FRET determination by fluorescence lifetime imaging microscopy (FLIM). Thanks to the very low excitation light levels of the time‐ and space‐correlated single photon counting (TSCSPC) method, FLIM acquisitions were achieved without donor photobleaching. Here, we show that photobleaching of CFP by a mercury lamp under the microscope induced a decrease in the mean fluorescence lifetime, which interfered with FRET determination between CFP and YFP. Importantly, the range of light‐induced variation of the mean fluorescence lifetime of CFP was not proportional to the decrease in the steady state fluorescence intensity and varied from cell to cell. The choice of the CFP/YFP pair therefore requires that the cells be observed and analyzed at very low light levels during the whole FRET experiment. In contrast, the GFP/mCherry pair provided an accurate FRET measurement by FLIM, even if some GFP photobleaching took place. We thus demonstrate that CFP can be an unreliable donor for FRET determination in living cells, due to its photosensitivity properties. We demonstrate that the GFP/mCherry pair is better suited for FRET measurement by FLIM in living cells than the CFP/YFP pair. Microsc. Res. Tech., 2006. © 2006 Wiley‐Liss, Inc.
