Authors: Gelbar Nicholas W. , Anderson Candace , McCarthy Scott , Buggey Tom 
Published: December 2011

AbstractVideo self‐modeling demonstrates promise as an intervention strategy to improve outcomes in individuals with autism spectrum disorders. This article summarizes the empirical evidence supporting the use of video self‐modeling with individuals with autism spectrum disorders to increase language and communication, increase social skills, modify behavior, and teach functional skills. A comparison of the empirical evidence supporting the use of video self‐modeling with other video modeling interventions is also provided. The use of video self‐modeling as part of a continuum of strategies for this population is supported by the current research base. © 2011 Wiley Periodicals, Inc.
Augmented self‐modeling as an intervention for selective mutism
Authors: Kehle Thomas J. , Bray Melissa A. , Byer‐alcorace Gabriel F. , Theodore Lea A. , Kovac Lisa M. 
Published: December 2011

AbstractSelective mutism is a rare disorder that is difficult to treat. It is often associated with oppositional defiant behavior, particularly in the home setting, social phobia, and, at times, autism spectrum disorder characteristics. The augmented self‐modeling treatment has been relatively successful in promoting rapid diminishment of selective mutism and the associated features. Further, it is perhaps the least intrusive of the treatments currently used. © 2011 Wiley Periodicals, Inc.
Large‐scale length and time‐scales for use with stochastic convective parametrization
Authors: Keane R. J. , Plant R. S. 
Published: December 2011

AbstractMany numerical models for weather prediction and climate studies are run at resolutions that are too coarse to resolve convection explicitly, but too fine to justify the local equilibrium assumed by conventional convective parametrizations. The Plant–Craig (PC) stochastic convective parametrization scheme, developed in this paper, solves this problem by removing the assumption that a given grid‐scale situation must always produce the same sub‐grid‐scale convective response. Instead, for each time step and grid point, one of the many possible convective responses consistent with the large‐scale situation is randomly selected. The scheme requires as input the large‐scale state as opposed to the instantaneous grid‐scale state, but must nonetheless be able to account for genuine variations in the large‐scale situation. Here we investigate the behaviour of the PC scheme in three‐dimensional simulations of radiative–convective equilibrium, demonstrating in particular that the necessary space–time averaging required to produce a good representation of the input large‐scale state is not in conflict with the requirement to capture large‐scale variations. The resulting equilibrium profiles agree well with those obtained from established deterministic schemes, and with corresponding cloud‐resolving model simulations. Unlike the conventional schemes, the statistics for mass flux and rainfall variability from the PC scheme also agree well with relevant theory and vary appropriately with spatial scale. The scheme is further shown to adapt automatically to changes in grid length and in forcing strength. Copyright © 2011 Royal Meteorological Society
Licensing‐in fosters rapid invention! the effect of the grant‐back clause and technological unfamiliarity
Authors: Leone Maria Isabella , Reichstein Toke 
Published: December 2011

AbstractDrawing on contractual economics and innovation management, licensing‐in is hypothesized to accelerate licensees' invention process. Studying a matched dataset of licensees and non‐licensees, licensees are shown to be faster at inventing, but the effect is negated if the license includes a grant‐back clause, shifting incentives from licensee to licensor. Also, the effect is significantly reduced if the licensee is unfamiliar with the licensed technology. The effect of the grant‐back clause is offset if the licensee is unfamiliar with the licensed technology, suggesting that the licensee retains the incentives to invent under these circumstances.

AbstractSpatially overlapping plates in tiled configurations represent designs that are observed widely in nature (e.g., fish and snake scales) and man‐made systems (e.g., shingled roofs) alike. This imbricate architecture offers fault‐tolerant, multifunctional capabilities, in layouts that can provide mechanical flexibility even with full, 100% areal coverages of rigid plates. Here, the realization of such designs in microsystems technologies is presented, using a manufacturing approach that exploits strategies for deterministic materials assembly based on advanced forms of transfer printing. The architectures include heterogeneous combinations of silicon, photonic, and plasmonic scales, in imbricate layouts, anchored at their centers or edges to underlying substrates, ranging from elastomer sheets to silicon wafers. Analytical and computational mechanics modeling reveal distributions of stress and strain induced by deformation, and provide some useful design rules and scaling laws.
Three‐dimensional computer‐aided finite element method retrofitting modeling and non‐destructive testing techniques for the assessment of actual existing high‐rise fire‐damaged reinforced concrete building
Authors: Wasim Muhammad , Hussain Raja Rizwan 
Published: December 2011

SUMMARYConcrete is generally fire resistant. A fire in a concrete structure rarely results in a serious damage as to require substantial demolition. But, loss of the utility of a building could result in serious financial consequences for the owner, which calls for immediate reinstatement. To work out proper and efficient repair strategy, however, would require a thorough investigation of the effect of fire on the structural properties of the concrete and steel; the significance which any permanent change in material characteristics may have on the future structural performance of the member; the feasibility of repairs to compensate of any unacceptable reduction in structural performance, durability, and so on; and the influence which fire exposure of individual member may have on the performance of the entire structure. These all said tasks are dependent on the complete analysis of the fire‐damaged building. Without it, no repair works estimation, extent of repair and kind of repair can be carried out for the fire‐damaged buildings. Therefore, the impeccable analysis and design is of utmost importance for repair of such buildings after preliminary investigation of the extent of fire damages to the concrete structural members. This forms the basis of this research study, which aims at detailed analysis and design of the actual existing high‐rise fire‐damaged buildings for fire retrofitting and assessment of fire damages by non‐destructive techniques. Fire damages in buildings due to explosion, accidents or by some other reasons cause severe structural damages. The structural integrity of existing buildings is now a burning issue. Analytical, theoretical and design‐cum‐construction techniques are constantly being reviewed by government agencies and engineering consultants. Therefore, researchers are delving into this matter to find the best retrofitting techniques for fire‐damaged buildings. This paper is an outcome of such detailed research studies. It covers the actual case study of existing buildings, review of existing knowledge for fire damages and their mitigation and protective design technologies, and analytical and computational techniques, which have limited research data. In this study, Extended 3D Analysis of Building Systems (ETABS) is used as software for fire retrofitting analysis, and UBC‐97 is used as a code for the fire analysis and design. The ETABS building model is verified by manual calculations as well. Copyright © 2011 John Wiley & Sons, Ltd.
Life‐cycle cost assessment of mid‐rise and high‐rise steel and steel–reinforced concrete composite minimum cost building designs
Authors: Lagaros Nikos D. , Magoula Efrossini 
Published: December 2011

SUMMARYThe traditional trial‐and‐error design approach is inefficient to determine an economical design satisfying also the safety criteria. Structural design optimization, on the other hand, provides a numerical procedure that can replace the traditional design approach with an automated one. The objective of this work is to propose a performance‐based seismic design procedure, formulated as a structural design optimization problem, for designing steel and steel–reinforced concrete composite buildings subject to interstorey drift limitations. For this purpose, eight test examples are considered, in particular four steel and four steel–reinforced concrete composite buildings are optimally designed with minimum initial cost. Life‐cycle cost analysis (LCCA) is considered as a reliable tool for measuring the damage cost due to future earthquakes that will occur during the design life of a structure. In this study, LCCA is employed for assessing the optimum designs obtained for steel and steel–reinforced concrete composite design practices. Copyright © 2011 John Wiley & Sons, Ltd.
Enhancing the high speed downlink packet access operation of 3G WCDMA systems
Authors: Skoutas Dimitrios N. , Skianis Charalabos 
Published: December 2011

ABSTRACTIn high‐speed downlink packet access (HSDPA), the combination of adaptive modulation and coding, hybrid automatic repeat request, and an extended multicode operation has replaced two fundamental aspects of wideband code division multiple access systems, namely, variable spreading factor and fast power control. Despite its enhanced characteristics, the HSDPA operation can be problematic when the majority of incoming traffic load consists of low data rate delay‐sensitive services such as mobile voice‐over‐Internet Protocol. To tackle this case, we propose an enhanced HSDPA operation that exploits multiple layers of the channelization code tree through a specifically designed packet scheduling and code allocation process. Enhanced HSDPA, when compared with the conventional HSDPA, provides a more flexible sharing of the available capacity and is able to increase the number of users that can be served with the required quality of service in terms of packet delay. The efficiency of the proposed scheme is confirmed by simulation results. Copyright © 2011 John Wiley & Sons, Ltd.

AbstractThree bis‐acylamide compounds, N1,N4‐bis(pyridin‐4‐yl)‐cyclohexane‐1, 4‐dicarboxamide (L1), 1, 1′‐(1, 3‐phenylenedicarbonyl‐)bis(1H‐1, 2, 3‐benzotriazole) (L2), and N1,N4‐bis(1H‐1, 2, 4‐triazole) phthalamide (L3) were synthesized. L1, L2, and a CuII complex based on L3 formulated as CuCl2(L3)2(en)2 (1) (en = ethylenediamine) were structurally characterized by single‐crystal X‐ray diffraction for the first time. L1, L2, and L3 exhibit different photoluminescence properties.

Published: December 2011

Abstract[MnBr(CO)5] reacts with one equivalent each of 1, 3, 5‐triaza‐7‐phosphaadamantane (PTA) and sodium diethyldithiocarbamate to afford the yellow MnI complex fac‐[Mn(S2CNEt2)(PTA)(CO)3]. Similarly, the same MnI precursor reacts with the sodium salt ofL‐histidine to give the tricarbonyl manganese(I) complex fac‐[Mn(his)(CO)3] in good yield as a yellow solid. Both compounds were spectroscopically and structurally characterised. The histidinato complex is soluble in water and its aqueous solutions are stable for more than 24 h. The CO releasing properties of the histidinato complex were studied with the myoglobin assay and establish this compound as a novel PhotoCORM, which liberates one of the three carbonyl ligands upon irradiation.
Hydrogen peroxide (H2O2) supply significantly improves xanthan gum production mediated by Xanthomonas campestris in vitro
Authors: Cheng Rong , Lin Lin , Zhang Yongkui 
Published: December 2011

Abstract
To improve xanthan gum productivity, a strategy of adding hydrogen peroxide (H2O2) was studied. The method could intensify oxygen supply through degradation of H2O2 to oxygen (O2). In shake flask testing, the xanthan gum yield reached 2.8% (improved by 39.4%) when adding 12.5 mM H2O2 after 24 h of fermentation. In fermentor testing, it was obvious that the oxygen conditions varied with the H2O2 addition time. Eventually, gum yield of 4.2% (w/w) was achieved (increased by 27.3%). Compared with the method of intense mixing and increasing the air flow rate, adding H2O2 to improve the dissolved oxygen concentration was more effective and much better. Moreover, addition of H2O2 improved the quality of xanthan gum; the pyruvate content of xanthan was 4.4% (w/w), higher than that of the control (3.2%).
Habitat selection of the Ortolan bunting Emberiza hortulana in Poland: predictions from large‐scale habitat elements
Authors: Kosicki Jakub Z. , Chylarecki Przemysław 
Published: December 2011

AbstractThe Ortolan bunting Emberiza hortulana was censused in Poland during the Common Breeding Birds Monitoring Project in 2003–2009. Data from 683 monitoring polygons, covering in total more than 0.23% of the country, were used in the analysis. Based on the data and environmental information gathered in GIS databases (Corine land cover “CLC2000 and 2006” database, digital elevation model “GTOPO30” dataset, “Wordclim” dataset, and NDVI dataset), we modeled a habitat‐ and spatial‐related variation of the Ortolan bunting's presence. Birds were recorded in 13.2% grid cells. The mean density was 0.5 individual/km2. We modeled the spatial presence of birds using multivariate adaptive regression splines (MARS). Then models were cross‐validated to check their consistency. The environment‐use model shows that the Ortolan bunting prefers extensively cultivated farmland dominated by non‐irrigated arable fields, small coniferous and mixed forests, complex cultivation patterns, and meadows. The preferred areas are located on lowlands in western and central parts of the country where the climate is the driest and warmest. Such a repeatable spatial pattern model of the population helped to create a predictive map of the Ortolan bunting's presence in Poland. The general rule is that the probability gradient of its presence increases from the northeastern part of the country to the central and southwestern parts of Poland. Additionally, the Ortolan bunting avoids severe continental climate and regions with dense ground‐level vegetation.

Published: December 2011

AbstractBackgroundReduction of apparent diffusion coefficient (ADC) values in white matter is not always ischaemic in nature.MethodsWe retrospectively analysed our MRI records featuring reduced ADC values in the centrum semiovale without grey matter involvement or significant vasogenic oedema.ResultsSeveral conditions showed the aforementioned MR findings: moose-horn lesions on coronal images in X-linked Charcot-Marie-Tooth disease; small fronto-parietal lesions in Menkes disease; marked signal abnormalities in the myelinised regions in the acute neonatal form of maple syrup urine disease; strip-like involvement of the corpus callosum in glutaric aciduria type 1; persistent periventricular parieto-occipital abnormalities in phenylketonuria; diffuse signal abnormalities with necrotic evolution in global cerebral anoxia or after heroin vapour inhalation; almost completely reversible symmetric fronto-parietal lesions in methotrexate neurotoxicity; chain-like lesions in watershed ischaemia; splenium involvement that normalises in reversible splenial lesions or leads to gliosis in diffuse axonal injury.ConclusionNeuroradiologists must be familiar with these features, thereby preventing misdiagnosis and inappropriate management.
Statistical properties of supersonic turbulence in the Lagrangian and Eulerian frameworks
Authors: Konstandin Lukas , Federrath Christoph , Klessen Ralf S. , Schmidt Wolfram 
Published: December 2011

AbstractWe present a systematic study of the influence of different forcing types on the statistical properties of supersonic, isothermal turbulence in both the Lagrangian and Eulerian frameworks. We analyse a series of high-resolution, hydrodynamical grid simulations with Lagrangian tracer particles and examine the effects of solenoidal (divergence-free) and compressive (curl-free) forcing on structure functions, their scaling exponents, and the probability density functions of the gas density and velocity increments. Compressively driven simulations show significantly larger density contrast, more intermittent behaviour, and larger fractal dimension of the most dissipative structures at the same root mean square Mach number. We show that the absolute values of Lagrangian and Eulerian structure functions of all orders in the integral range are only a function of the root mean square Mach number, but independent of the forcing. With the assumption of a Gaussian distribution for the probability density function of the velocity increments for large scales, we derive a model that describes this behaviour.
Effects of acoustic-streaming-induced flow in evaporating nanofluid droplets
Authors: Saha Abhishek , Basu Saptarshi , Kumar Ranganathan 
Published: December 2011

AbstractWe study the effect of acoustic streaming on nanoparticle motion and morphological evolution inside an acoustically levitated droplet using an analytical approach coupled with experiments. Nanoparticle migration due to internal recirculation forms a density stratification, the location of which depends on initial particle concentration. The time scale of density stratification is similar to that of perikinetic-driven agglomeration of particle flocculation. The density stratification ultimately leads to force imbalance leading to a unique bowl-shaped structure. Our analysis shows the mechanism of bowl formation and how it is affected by particle size, concentration, internal recirculation and fluid viscosity.
Comparative study of orbital involvement in invasive and non-invasive fungal sinusitis
Authors: Chandrasekharan R , Thomas M , Rupa V 
Published: December 2011

AbstractObjective:To investigate differences in orbital involvement in patients with invasive versus non-invasive fungal sinusitis.Method:One hundred consecutive cases of fungal sinusitis were assessed clinically and by computed tomography scan to evaluate orbital involvement.Results:Clinical orbital involvement was more common in invasive (73.5 per cent) than non-invasive (12.1 per cent) fungal sinusitis (p = 0.000). Computed tomography scanning showed similar orbital involvement in both groups, except for erosion of the floor of the orbit, which was more common in patients with invasive fungal sinusitis (p = 0.01). Extra-ocular muscle enlargement (44.4 vs 4 per cent, p = 0.01) and optic atrophy (44.4 vs 0 per cent, p = 0.003) were more common in chronic than acute invasive fungal sinusitis. Four patients (16 per cent) with acute invasive fungal sinusitis had no evidence of orbital involvement on scanning, despite clinical evidence of optic atrophy.Conclusion:Orbital involvement is more common in invasive than non-invasive fungal sinusitis. The difference is more evident clinically than on computed tomography scanning. Patients with acute invasive fungal sinusitis may have limited evidence of orbital involvement on scanning, despite extensive clinical disease.
Antiplatelet therapy in ENT surgery: a review
Authors: Sylvester D C , Coatesworth A P 
Published: December 2011

AbstractIntroduction:Antiplatelet agents such as aspirin and clopidogrel are increasingly encountered in clinical practice. Otorhinolaryngological surgeons are involved in the peri-operative decision of whether to continue treatment and risk haemorrhage or to discontinue treatment and risk thrombosis.Methods:Literature relating to the risk of spontaneous or operative haemorrhage was reviewed. The morbidity and mortality associated with cessation of agents was evaluated. Published guidelines were also evaluated. A protocol for the management of antiplatelet agents in the peri-operative period, with particular reference to ENT operations, is presented.Conclusion:Significant morbidity and mortality is associated with the premature cessation of antiplatelet agents. Data from cardiac surgery suggest that operative blood loss only marginally increases in patients on aspirin and clopidogrel. However, the management of antiplatelet agents in the peri-operative period should be made after multidisciplinary consultation.
What hinders child semantic computation: children's universal quantification and the development of cognitive control
Authors: MINAI UTAKO , JINCHO NOBUYUKI , YAMANE NAOTO , MAZUKA REIKO 
Published: December 2011

ABSTRACTRecent studies on the acquisition of semantics have argued that knowledge of the universal quantifier is adult-like throughout development. However, there are domains where children still exhibit non-adult-like universal quantification, and arguments for the early mastery of relevant semantic knowledge do not explain what causes such non-adult-like interpretations. The present study investigates Japanese four- and five-year-old children's atypical universal quantification in light of the development of cognitive control. We hypothesized that children's still-developing cognitive control contributes to their atypical universal quantification. Using a combined eye-tracking and interpretation task together with a non-linguistic measure of cognitive control, we revealed a link between the achievement of adult-like universal quantification and the development of flexible perspective-switch. We argue that the development of cognitive control is one of the factors that contribute to children's processing of semantics.

Published: December 2011

AbstractCongenital aortocaval fistula is a very rare anomaly. Clinically, it resembles conditions that cause left-to-right shunt of blood. We report a case of such anomaly in combination with a secundum atrial septal defect in a 13-month-old girl who presented with failure to thrive and exertional respiratory symptoms. The aortocaval fistula was occluded percutaneously using an Amplatzer®Duct Occluder.
