Energy Transfer at the Zeolite L Boundaries: Towards Photo‐ and Electroresponsive Materials
Authors: Cucinotta Fabio , Guenet Aurélie , Bizzarri Claudia , Mróz Wojciech , Botta Chiara , Milián‐Medina Begoña , Gierschner Johannes , De Cola Luisa 
Published: December 2013

AbstractA series of iridium(III) compounds have been used as stopper molecules at the pore openings of zeolite L and act as effective donor units for transferring excitation energy to dye molecules entrapped within the zeolite channels. The synthesis and photophysical characterization of the new iridium(III) complexes are described, along with Förster resonance energy‐transfer experiments. Transfer efficiencies for the studied systems are discussed on the basis of the role played by the localization of the donor excited state and the acceptor distribution in the channels. Because iridium(III) complexes can also be electrically excited, the electroluminescent behavior of donor–acceptor zeolite systems can be explored, by embedding them into a polymeric active layer and constructing light‐emitting devices (LEDs). Novel hybrid LEDs can be fabricated with emission from the dyes entrapped into the zeolites and sensitized by the electro‐responsive iridium(III) complex.
On the predictability of next generation mobile network traffic using artificial neural networks
Authors: Loumiotis I. , Adamopoulou E. , Demestichas K. , Stamatiadi T. , Theologou M. 
Published: December 2013

SummaryThough the introduction of the new 4th Generation mobile access technologies promises to satisfy the increasing bandwidth demand of the end‐users, it poses in parallel the need for novel resource management approaches at the side of the base station. To this end, schemes that try to predict the forthcoming bandwidth demand using supervised learning methods have been proposed in the literature. However, there are still open issues concerning the training phase of such methods. In the current work, the authors propose a novel scheme that dynamically selects a proper training set for artificial neural network prediction models, based on the statistical characteristics of the collected data. It is demonstrated that an initial statistical processing of the collected data and the subsequent selection of the training set can efficiently improve the performance of the prediction model. Finally, the proposed scheme is validated using network traffic collected by real, fully operational base stations. Copyright © 2013 John Wiley & Sons, Ltd.
Is the hibiscus harlequin bug aposematic? The importance of testing multiple predators
Authors: Fabricant Scott A. , Smith Carolynn L. 
Published: December 2013

AbstractAposematism involves predators learning conspicuous signals of defended prey. However, prey species utilize a wide range of chemical (or physical) defenses, which are not likely to be equally aversive to all predators. Aposematism may therefore only be effective against a physiologically sensitive subset of potential predators, and this can only be identified through behavioral testing. We studied the emerging model organism Tectocoris diophthalmus (Heteroptera: Scutelleridae), an aposematically colored but weakly defended shieldback stinkbug, to test the efficacy of its defenses against a suite of predator types. We predicted the bugs' defenses would be ineffectual against both experienced and naïve birds but aversive to predaceous insects. Surprisingly, the opposite pattern was found. Both habituated wild passerines and naïve chickens avoided the bugs, the chickens after only one or two encounters. To avian predators, T. diophthalmus is aposematic. However, praying mantids showed no repellency, aversion, or toxicity associated with adult or juvenile bugs after multiple trials. Comparison with prior studies on mantids using bugs with chemically similar but more concentrated defenses underscores the importance of dose in addition to chemical identity in the efficacy of chemical defenses. Our results also emphasize the importance of behavioral testing with multiple ecologically relevant predators to understand selective pressures shaping aposematic signals and chemical defenses.
Electrochromic Switching and Microkinetic Behaviour of Oxazine Derivatives and Their Applications

Published: December 2013

AbstractDetailed electrochromic properties including the microkinetic switching behaviour of 2‐nitro‐ (P1) and 2,8‐dinitro‐5a‐[2‐(4‐dimethylaminophenyl)ethylene]‐6,6‐dimethyl‐5a,6‐dihydro‐12H‐indolo[2,1‐b][1,3]benzooxazine (P2) were investigated in both solution and indium tin oxide (ITO) devices with a dual‐wavelength time‐dependent spectra monitoring method for the first time. These two oxazine derivatives displayed improved fatigue resistance and colour reversibility towards electrical stimulation compared with conventional spiropyran derivatives. A new electrochromic mechanism was proposed based on the experimental results and on quantum chemical calculations. Owing to an electron‐withdrawing group para to the nitrogen of the indole fragment, P2 demonstrates better electro‐driven reversibility of structural transformation between ring‐open and ring‐closed isomers than P1.
Polytopic Bis(oxazoline)‐Based Ligands for the Development of Recoverable Catalytic Systems Applied to the Cyclopropanation Reaction
Authors: García José I. , García Jaime , Herrerías Clara I. , Mayoral José A. , Miñana Ana C. , Sáenz Carlos 
Published: December 2013

AbstractNew ditopic and tetratopic chiral ligands, based on the bis(oxazoline) moiety, have been synthesized and their copper complexes tested as catalysts in the benchmark asymmetric cyclopropanation reaction of styrene with ethyl diazoacetate. The polytopic nature of these ligands enables a release–capture strategy to efficiently recycle the enantioselective catalyst by precipitation of a coordination polymer at the end of the reaction. This strategy enables the self‐supported catalyst to be reused up to 20 times leading to good yields and enantioselectivities.
Us and them: Mood effects on ingroup projection
Authors: Machunsky Maya , Meiser Thorsten 
Published: December 2013

AbstractMood states affect judgments in general and intergroup judgments in particular. The aim of the present research was to show that ingroup projection is influenced by affective states in a similar way as ingroup bias. Varying mood states and relevance of the intergroup situation orthogonally, the results supported the hypotheses that positive mood in conjunction with low relevance and negative mood in conjunction with high relevance elicit higher levels of biased prototypicality perceptions compared to the other conditions of the design. Given substantial evidence from previous research that mood in conjunction with perceived relevance moderates motivated versus heuristic processing, we propose that the present results correspond with motivation‐ versus cognition‐based ingroup projection and suggest different processes underlying the phenomenon of relative ingroup prototypicality.

Analysis of Gaseous Flow Between Parallel Plates by Second‐ Order Velocity Slip and Temperature Jump Boundary Conditions
Authors: Kushwaha Hari Mohan , Sahu S.K. 
Published: December 2013

AbstractIn this study the momentum and energy equations are solved to analyze the flow between two parallel plates by employing second‐order velocity slip and temperature jump conditions. The flow is considered to be laminar, incompressible, hydrodynamically/thermally fully developed, and steady state. In addition to the isoflux condition, viscous dissipation is included in the analysis. Closed form expressions for the temperature field and Nusselt number are obtained as a function of the Knudsen number and Brinkman number. The Nusselt number obtained by employing the second‐order model is found to be lower compared to the continuum value and agrees well with the other theoretical models. © 2013 Wiley Periodicals, Inc.

In Vitro Investigations of Smart Drug Delivery Systems Based on Redox‐Sensitive Cross‐Linked Micelles
Authors: Cajot Sébastien , Schol Daureen , Danhier Fabienne , Préat Véronique , Gillet De Pauw Marie‐Claire , Jérôme Christine 
Published: December 2013

AbstractRedox‐sensitive micelles are designed by using block copolymers of different architectures composed of a hydrophilic block of poly(ethylene oxide), and hydrophobic blocks of poly(ϵ‐caprolactone) and poly(α‐azide‐ϵ‐caprolactone). Stability of these micelles is insured in diluted media by cross‐linking their core via the addition of a bifunctional cross‐linker, while redox sensitivity is provided to these micelles by inserting a disulfide bridge in the cross‐linker. The potential of these responsive micelles to be used as nanocarriers is studied in terms of cytotoxicity and cellular internalization. The release profiles are also investigated by varying the environment reductive strength.
Cultural Factors That Impact Brand Personification Strategy Effectiveness
Authors: Aguirre‐Rodriguez Alexandra 
Published: December 2013

ABSTRACTA brand personification is a human‐like portrayal of a product or brand that is designed to associate the brand with certain human characteristics. Brand personifications, such as fictional human characters (e.g., Mr. Clean), human‐like brand characters (e.g., Pillsbury doughboy), and product animations (e.g., M&M's characters), portray human‐like personality characteristics intended to shape consumers’ brand images. However, a brand personification strategy that appeals to consumers in one cultural context will not necessarily appeal to consumers in another cultural context. To explore cultural factors impacting brand personification strategies, a literature review was conducted. Ten research propositions were developed for future research and managerial implications were discussed.
Global attractivity and almost periodic solution of a discrete mutualism model with delays
Authors: Zhang Hui , Li Yingqi , Jing Bin 
Published: December 2013

AbstractIn this paper, we consider an almost periodic discrete Lotka–Volterra mutualism model with delays. We first obtain the permanence and global attractivity of the system. By means of an almost periodic functional hull theory and constructing a suitable Lyapunov function, sufficient conditions are obtained for the existence of a unique strictly positive almost periodic solution, which is globally attractive. An example together with numerical simulation indicates the feasibility of the main result. Copyright © 2013 John Wiley & Sons, Ltd.
Extracellular Hsp90 mediates an NF‐κB dependent inflammatory stromal program: Implications for the prostate tumor microenvironment
Authors: Bohonowych JE , Hance MW , Nolan KD , Defee M , Parsons CH , Isaacs JS 
Published: December 2013

BACKGROUNDThe tumor microenvironment (TME) plays an essential role in supporting and promoting tumor growth and progression. An inflammatory stroma is a widespread hallmark of the prostate TME, and prostate tumors are known to co‐evolve with their reactive stroma. Cancer‐associated fibroblasts (CAFs) within the reactive stroma play a salient role in secreting cytokines that contribute to this inflammatory TME. Although a number of inflammatory mediators have been identified, a clear understanding of key factors initiating the formation of reactive stroma is lacking.METHODSWe explored whether tumor secreted extracellular Hsp90 alpha (eHsp90α) may initiate a reactive stroma. Prostate stromal fibroblasts (PrSFs) were exposed to exogenous Hsp90α protein, or to conditioned medium (CM) from eHsp90α‐expressing prostate cancer cells, and evaluated for signaling, motility, and expression of prototypic reactive markers. In tandem, ELISA assays were utilized to characterize Hsp90α‐mediated secreted factors.RESULTSWe report that exposure of PrSFs to eHsp90 upregulates the transcription and protein secretion of IL‐6 and IL‐8, key inflammatory cytokines known to play a causative role in prostate cancer progression. Cytokine secretion was regulated in part via a MEK/ERK and NF‐κB dependent pathway. Secreted eHsp90α also promoted the rapid and durable activation of the oncogenic inflammatory mediator signal transducer and activator of transcription (STAT3). Finally, eHsp90 induced the expression of MMP‐3, a well‐known mediator of fibrosis and the myofibroblast phenotype.CONCLUSIONSOur results provide compelling support for eHsp90α as a transducer of signaling events culminating in an inflammatory and reactive stroma, thereby conferring properties associated with prostate cancer progression.

The arylpiperazine derivatives N‐(4‐cyanophenylmethyl)‐4‐(2‐diphenyl)‐1‐piperazinehexanamide and N‐benzyl‐4‐(2‐diphenyl)‐1‐piperazinehexanamide exert a long‐lasting inhibition of human serotonin 5‐HT7 receptor binding and cAMP signaling

Published: December 2013

AbstractWe performed a detailed in vitro pharmacological characterization of two arylpiperazine derivatives, compound N‐(4‐cyanophenylmethyl)‐4‐(2‐diphenyl)‐1‐piperazinehexanamide (LP‐211) previously identified as a high‐affinity brain penetrant ligand for 5‐hydroxytryptamine (serotonin) type 7 (5‐HT7) receptors, and its analog N‐benzyl‐4‐(2‐diphenyl)‐1‐piperazinehexanamide (MEL‐9). Both ligands exhibited competitive displacement of [3H]‐(2R)‐1‐[(3‐hydroxyphenyl)sulfonyl]‐2‐[2‐(4‐methyl‐1‐piperidinyl)ethyl]pyrrolidine ([3H]‐SB‐269970) radioligand binding and insurmountable antagonism of 5‐carboxamidotryptamine (5‐CT)‐stimulated cyclic adenosine monophosphate (cAMP) signaling in human embryonic kidney (HEK293) cells stably expressing human 5‐HT7 receptors. They also inhibited forskolin‐stimulated adenylate cyclase activity in 5‐HT7‐expressing HEK293 cells but not in the parental cell line. The compounds elicited long‐lasting (at least 24 h) concentration‐dependent inhibition of radioligand binding at 5‐HT7‐binding sites in whole‐cell radioligand binding assays, after pretreatment of the cells with the compounds and subsequent compound removal. In cAMP assays, pretreatment of cells with the compounds rendered 5‐HT7 receptors unresponsive to 5‐CT and also rendered 5‐HT7‐expressing HEK293 cells unresponsive to forskolin. Compound 1‐(2‐biphenyl)piperazine (RA‐7), a known active metabolite of LP‐211 present in vivo, was able to partially inhibit 5‐HT7 radioligand binding in a long‐lasting irreversible manner. Hence, LP‐211 and MEL‐9 were identified as high‐affinity long‐acting inhibitors of human 5‐HT7 receptor binding and function in cell lines. The detailed in vitro characterization of these two pharmacological tools targeting 5‐HT7 receptors may benefit the study of 5‐HT7 receptor function and it may lead to the development of novel selective pharmacological tools with defined functional properties at 5‐HT7 receptors.
Quantitative Environmental Footprints and Sustainability Evaluation of Contaminated Land Remediation Alternatives for Two Case Studies
Authors: Ferdos Farzad , Rosén Lars 
Published: December 2013

Since the US Environmental Protection Agency (US EPA) launched its “green remediation” program and EU member states began to reassess their national regulations for environmental remediation in order to reach a Europe‐wide consensus on policy and standards, the need and interest for sustainable remediation of contaminants from brownfields has grown considerably. Concomitantly, the ability to calculate and assess the suitability as well as the environmental footprints and associated risks of a growing number of remediation techniques has become a priority. The authors quantitatively evaluate the differences between various remediation techniques, and for this purpose, a number of ex situ and in situ remediation techniques are adapted to model 21 remediation scenarios for two contaminated sites in the Gothenburg region of Sweden: the Bohus Varv site on the Göta älv river bank and the Hexion site in Mölndal. A wide range of quantitative results for these models are presented, compared, and analyzed.Based on the results from both projects, it is concluded that: (1) remediation techniques requiring long distance residual transportation have significant footprints, except the transportation of contaminated residuals by train due to Swedish energy production conditions; (2) residual transportation by ship results in much higher SOx, NOx, and particle releases compared to the other alternatives; and (3) residual transporation by truck results in high accident risks. Finally, activities powered by electricity result in a reduced footprint compared to activities powered by fossil fuels, considering Swedish energy production conditions.The authors conducted a cross‐benefit analysis of SiteWiseTM applications which recognizes its potential as a tool for presenting life cycle assessment analyses with appropriate system boundary definitions and an easy inventory analysis process. Results from this tool provide valuable support to decision makers aiming at more sustainable remediation. © 2013 Wiley Periodicals, Inc.

Published: December 2013

Abstract
Direct correlation have been observed between certain trace element and hydrocarbon anomalies in the near subsurface soils of Vindhyan basin, India. This relationship with hydrocarbon is very useful in hydrocarbon exploration. 52 soil samples from Vindhyan basin were collected from a depth of 2.5m. All the soil samples were analyzed for light hydrocarbon, isotope and trace element concentrations. The adsorbed light gaseous hydrocarbon analyses show the presence of methane (8 - 328 ppb), ethane (0 - 27 ppb) and propane (0 -11 ppb) respectively and these values indicate the presence of hydrocarbon micro-seepage in the study area. The carbon isotopic values determined for methane and ethane for these soil samples are (-26.41 to -47.70 ‰ PDB) and (-20.07 to -35.30 ‰ PDB) respectively and they are thermogenic in nature. The trace element concentrations of nickel (33-220 ppm), vanadium (72-226 ppm), copper (20- 131 ppm), chromium (94-205 ppm), zinc (66-561 ppm) and cobalt (9-39 ppm) have higher than the normal concentrations in soils. Trace element concentrations are used to plot with the data obtained from light gaseous hydrocarbon concentrations and carbon isotopic values of soil samples of the Vindhyan basin. Trace element anomalies have been observed around the hydrocarbon anomalies in the study area.
UTCHEM Model Application for Prediction of Crude Oil Removal from Contaminated Sand Columns
Authors: Asadollahfard G. , Khodadi A. , Javadifar N. 
Published: December 2013

Abstract
Soil pollution by crude oil is a challenging environmental issue for oil producing countries. Several methods have been developed for remediation of the contaminated soil including washing with different detergents. In this work, we applied UTCHEM simulator model to the sand columns polluted by 10000 and 30000 ppm of crude oil which was treated with 0.05, 0.1 and 0.2 wt% of a biological detergent, saponin. The results showed a good agreement between simulated and pilot study. The maximum remediation was 61% with a pH of 9 when we utilized 0.2 wt% saponin for the column contaminated with 30000 ppm of crude oil. 47% remediation was achieved with a pH of 9 when 0.1wt% of detergent was applied to the same column. Sensitivity analysis indicated an increase in remediation by increasing the pH with the optimum pH of 11. The best possible concentrations of surfactant solutions were 0.1 and 0.2 wt% for 10000 and 30000 ppm pollution, respectively, resulting in crude oil removal efficiencies of 69% and 72%, respectively. Simulation results also indicated that an increase in the permeability of the sand columns would also result in an increased remediation.
The Impact of Migration and Remittances on Wealth Accumulation and Distribution in Rural Thailand
Authors: Garip Filiz 
Published: December 2013

AbstractThis article studies the impact of internal migration and remittance flows on wealth accumulation and distribution in 51 rural villages in Nang Rong, Thailand. Using data from 5,449 households, the study constructs indices of household productive and consumer assets with principal component analysis. The changes in these indices from 1994 to 2000 are modeled as a function of households’ prior migration and remittance behavior with ordinary least squares, matching, and instrumental variable methods. The findings show that rich households lose productive assets with migration, potentially because of a reduction in the labor force available to maintain local economic activities, while poor households gain productive assets. Regardless of wealth status, households do not gain or lose consumer assets with migration or remittances. These results suggest an equalizing effect of migration and remittances on wealth distribution in rural Thailand.
