Effects of Lightness‐Location Congruency on Consumers’ Purchase Decision‐Making
Authors: Sunaga Tsutomu , Park Jaewoo , Spence Charles 
Published: October 2016

ABSTRACTA considerable body of psychological and neuroscientific research has demonstrated the existence of robust sensory correspondences between various features, attributes, or dimensions of experience in different sensory modalities. Despite findings indicating the importance of sensory correspondences to human information processing, research on purchase decision‐making has not to date focused sufficiently on this phenomenon. The present study examines how the lightness of packaging colors, and the location of products on a display shelf interact to affect consumers’ purchase decision‐making via perceived visual heaviness. As predicted, a display with light (dark) colored products positioned in the upper (lower) shelf positions increases shoppers’ perceptual fluency and facilitates their visual search, thus leading to the suggestion that “light” (heavy) locations are most appropriate for light (dark) colored products. Moreover, the lightness‐location congruent display is shown to influence people's choice behavior positively as well. This research also demonstrates that when consumers consider the lightness (in terms of their weight) of the products, they are more likely to choose light (vs. dark) colored products located in the upper shelf positions. These results therefore demonstrate that consumers’ purchase decision‐making may be promoted by in‐store environments designed to be congruent with their sensory correspondences.

Published: October 2016

The importance of the development of kinetic modeling tools to mechanistically understand and design bulk and solution reversible addition fragmentation chain transfer (RAFT) polymerization is highlighted. Both deterministic and stochastic kinetic modeling methods are covered, considering a detailed reaction scheme and accounting for the impact of diffusional limitations on the reaction rates. A novel strategy is introduced to fundamentally calculate the diffusional contributions for the apparent RAFT addition and fragmentation rate coefficients. Next to literature examples, case studies are included to demonstrate that detailed theoretical studies are indispensable to completely map the effect of the polymerization conditions and RAFT agent reactivity on the control over microstructural properties and the overall polymerization time. Guidelines for future kinetic modeling activities are formulated to enhance joined theoretical and experimental research.image

AbstractBackgroundAutonomic dysfunction is common in the later stages of Parkinson's disease (PD), but less is known about its presence and severity in early disease.ObjectiveTo analyze features of autonomic dysfunction in recent onset PD cases, and their relationship to motor severity, medication use, other nonmotor symptoms (NMS), and quality‐of‐life scores.MethodsDetailed patient‐reported symptoms of autonomic dysfunction were assessed in a multicenter cohort study in PD cases that had been diagnosed within the preceding 3.5 years.ResultsThere were 1746 patients (1132 males, 65.2%), mean age 67.6 years (SD 9.3), mean disease duration 1.3 years (SD 0.9), mean Movement Disorder Society Unified Parkinson's Disease Rating Scale motor score 22.5 (SD 12.1). Orthostatic symptoms were reported by 39.6%, male erectile dysfunction by 56.1%, and female anorgasmia by 57.4%. Sialorrhea was an issue in 51.4% of patients, constipation in 43.6%, and dysphagia in 20.1%. Autonomic features increased with higher modified Hoehn and Yahr stages (P < 0.001). The severity of autonomic dysfunction was associated with the postural instability gait difficulty motor phenotype [β‐coefficient 1.7, 95% confidence interval (CI) 0.7, 2.6, P < 0.001], depression (β‐coefficient 4.1, CI 3.0, 5.2, P < 0.001), and excess daytime sleepiness (β‐coefficient 3.1, CI 1.9, 4.2, P < 0.001). Dopamine agonists were the only drug class associated with greater autonomic dysfunction (P = 0.019). The severity of autonomic dysfunction strongly correlated with the presence of other NMS (ρ = 0.717, P < 0.001), and with poorer quality‐of‐life scores (ρ = 0.483, P < 0.001).ConclusionsAutonomic dysfunction is common in early PD. Autonomic dysfunction correlates with the presence of other NMS, and with worse quality of life.

Published: October 2016

AbstractThe availability of appropriate stimulus material is a key concern for an experimental approach to research on alcohol use disorders (AUDs). A large number of such stimuli are necessary to evoke relevant alcohol‐related associations. We report the development of a large stimulus database consisting of 457 pictures of alcoholic beverages and 398 pictures of neutral objects. These stimuli were rated by 18 inpatients hospitalized due to severe AUD and 18 healthy controls along four dimensions: arousal, valence, alcohol‐relatedness, and craving. Physical parameters of the pictures were assessed.After outlier removal, 831 stimuli that were characterized as either alcohol‐related or neutral were retained in the final stimulus pool. Alcohol‐related pictures (versus neutral pictures) evoked higher arousal, more craving and were judged to have higher alcohol‐relatedness and a more negative valence. Group comparisons indicated that in patients, neutral pictures evoked more craving and had higher alcohol‐relatedness than they did in controls. Physical parameters such as visual complexity, luminance, and color were extracted from these pictures, and extreme values were normalized to minimize mean differences between alcoholic and neutral stimuli. The pictures met the qualitative requirements for (neurophysiological) research. A data file containing rating values and physical parameters will be provided upon request.
Activation and Deactivation of Phillips Catalyst for Ethylene Polymerization Using Various Activators
Authors: Zeng Yanning , Chammingkwan Patchanee , Baba Ryuki , Taniike Toshiaki , Terano Minoru 
Published: October 2016

The present article reveals important roles of metal alkyl activators in tuning the performance of the Phillips catalyst in ethylene polymerization. The addition of aluminum alkyl aids the activation of the catalyst, while excess addition leads to the loss of the activity. The balance between the activation and deactivation depends on the type of employed aluminum alkyl, and tri‐n‐octylaluminum offers the most efficient catalyst usage by preferentially suppressing the deactivation. The passivation of aluminum trialkyl with a hindered phenol mildens not only the deactivation but also chain transfer reactions, leading to an increment of high molecular weight fractions.image

Published: October 2016

PurposeTo optimize the production of hyperpolarized 13C‐bicarbonate from the decarboxylation of hyperpolarized [1‐13C]pyruvate and use it to image pH in the lungs and heart of rats with acute lung injury.MethodsTwo forms of catalysis are compared calorimetrically to maximize the rate of decarboxylation and rapidly produce hyperpolarized bicarbonate from pyruvate while minimizing signal loss. Rats are injured using an acute lung injury model combining ventilator‐induced lung injury and acid aspiration. Carbon images are obtained from both healthy (n = 4) and injured (n = 4) rats using a slice‐selective chemical shift imaging sequence with low flip angle. pH is calculated from the relative
and CO2 signals using the Henderson‐Hasselbalch equation.ResultsIt is demonstrated that base catalysis is more effective than metal‐ion catalysis for this decarboxylation reaction. Bicarbonate polarizations up to 17.2% are achieved using the base‐catalyzed reaction. A mean pH difference between lung and heart of 0.14 pH units is measured in the acute lung injury model. A significant pH difference between injured and uninjured lungs is also observed.ConclusionIt is demonstrated that hyperpolarized 13C‐bicarbonate can be efficiently produced from the base‐catalyzed decarboxylation of pyruvate. This method is used to obtain the first regional pH image of the lungs and heart of an animal. Magn Reson Med 78:1121–1130, 2017. © 2016 International Society for Magnetic Resonance in Medicine.
Multi‐scale graph‐cut algorithm for efficient water‐fat separation
Authors: Berglund Johan , Skorpil Mikael 
Published: October 2016

PurposeTo improve the accuracy and robustness to noise in water‐fat separation by unifying the multiscale and graph cut based approaches toB0‐correction.MethodsA previously proposed water‐fat separation algorithm that corrects forB0field inhomogeneity in 3D by a single quadratic pseudo‐Boolean optimization (QPBO) graph cut was incorporated into a multi‐scale framework, where field map solutions are propagated from coarse to fine scales for voxels that are not resolved by the graph cut. The accuracy of the single‐scale and multi‐scale QPBO algorithms was evaluated against benchmark reference datasets. The robustness to noise was evaluated by adding noise to the input data prior to water‐fat separation.ResultsBoth algorithms achieved the highest accuracy when compared with seven previously published methods, while computation times were acceptable for implementation in clinical routine. The multi‐scale algorithm was more robust to noise than the single‐scale algorithm, while causing only a small increase (+10%) of the reconstruction time.ConclusionThe proposed 3D multi‐scale QPBO algorithm offers accurate water‐fat separation, robustness to noise, and fast reconstruction. The software implementation is freely available to the research community. Magn Reson Med 78:941–949, 2017. © 2016 International Society for Magnetic Resonance in Medicine
The problem Of muscle hypertrophy: Revisited
Authors: Buckner Samuel L. , Dankel Scott J. , Mattocks Kevin T. , Jessee Matthew B. , Mouser J. Grant , Counts Brittany R. , Loenneke Jeremy P. 
Published: October 2016

ABSTRACTIn this paper we revisit a topic originally discussed in 1955, namely the lack of direct evidence that muscle hypertrophy from exercise plays an important role in increasing strength. To this day, long‐term adaptations in strength are thought to be primarily contingent on changes in muscle size. Given this assumption, there has been considerable attention placed on programs designed to allow for maximization of both muscle size and strength. However, the conclusion that a change in muscle size affects a change in strength is surprisingly based on little evidence. We suggest that these changes may be completely separate phenomena based on: (1) the weak correlation between the change in muscle size and the change in muscle strength after training; (2) the loss of muscle mass with detraining, yet a maintenance of muscle strength; and (3) the similar muscle growth between low‐load and high‐load resistance training, yet divergent results in strength.

Efficient wave propagation simulation on quadtree meshes using SBFEM with reduced modal basis
Authors: Gravenkamp Hauke , Saputra Albert A. , Song Chongmin , Birk Carolin 
Published: October 2016

SummaryWe apply a combination of the transient scaled boundary finite element method (SBFEM) and quadtree‐based discretization to model dynamic problems at high frequencies. We demonstrate that the current formulation of the SBFEM for dynamics tends to require more degrees of freedom than a corresponding spectral element discretization when dealing with smooth problems on regular domains. Thus, we improve the efficiency of the SBFEM by proposing a novel approach to reduce the number of auxiliary variables for transient analyses. Based on this improved SBFEM, we present a modified meshing procedure, which creates a quadtree mesh purely based on the geometry and allows arbitrary sizes and orders of elements, as well as an arbitrary number of different materials. The discretization of each subdomain is created automatically based on material parameters and the highest frequency of interest. The transition between regions of different properties is straightforward when using the SBFEM. The proposed approach is applied to image‐based analysis with a particular focus on geological models.

Evidence for Migration Influx into the Ancient Greek Colony of Metaponto: A Population Genetics Approach Using Dental Nonmetric Traits
Authors: Rathmann H. , Saltini Semerari G. , Harvati K. 
Published: October 2016

AbstractAncient Greek colonies were founded by Greek seafarers all along the Mediterranean coast as early as the eighth centurybc. Despite extensive archaeological and historical research, the population structure of the inhabitants of Greek colonies and their relationship to indigenous populations are still debated. Here, we perform a biodistance analysis to reconstruct migration and gene flow between the ancient Greek colony of Metaponto (southern Italy) and indigenous groups in the surrounding hinterland (900–250bc). We collected dental nonmetric trait data of 355 human skeletons from the indigenous Italic sites of Santa Maria d'Anglona, Incoronata and Passo di Giacobbe. This data set is compared with an urban and rural sample of the Greek colony of Metaponto comprising 351 individual dentitions. The R‐matrix approach is used to estimate inter‐population relationships andFST. The resulting kinship coefficients indicate that the three indigenous groups exhibit greater similarity to each other and possess lesser similarity to the two Metapontian samples. Interestingly, the two samples of Metaponto are least similar to each other, although they are geographically very close. TheFSTestimates confirm this pattern and reveal greater biological variation between the two nearby Metaponto samples (FST = 0.0603) than between the three geographically fairly distant indigenous groups (FST = 0.0389). We conclude that the Greek colony of Metaponto included large numbers of people with diverse geographical origins, whereas the indigenous Italic communities of the surrounding hinterland exhibited high levels of homogeneity and cohesion.

Morphometric Analysis of Camelid Remains from the Alero Deodoro Roca (ADR) Site (Córdoba, Argentina). An Attempt to Characterise Body‐Size Variability in Sierras Pampeanas Australes Region
Authors: Costa T. , Izeta A. 
Published: October 2016

AbstractThis paper focuses in the morphometric analyses of Lama guanicoe remains recovered from the hunter–gatherer archaeological site Alero Deodoro Roca, located at Sierras Pampeanas Australes region (Córdoba Argentina), an area that has little information on the body‐size variability of these artiodactyls. Because of the sparse osteometric data in the region, we focused on determining inter‐intraspecific differentiation of wild camelids through corroborated osteometric techniques and multivariate statistical analyses of proximal phalanges. Our results showed a clear interspecific differentiation between modern vicuñas and archaeological specimens. We could also distinguish at least three guanaco size groups (small, medium and large) with the archaeological remains from the late Holocene (3000–3600 bp) of the site, presenting medium‐size characteristics. Finally this paper aims at establishing a first approach in the characterisation of guanaco body size in the mountainous region of Córdoba. Copyright © 2016 John Wiley & Sons, Ltd.
Set‐valued observer‐based active fault‐tolerant model predictive control
Authors: Xu Feng , Puig Vicenç , Ocampo‐Martinez Carlos , Wang Xueqian 
Published: October 2016

SummaryThis paper proposes an integrated actuator and sensor active fault‐tolerant model predictive control scheme. In this scheme, fault detection is implemented by using a set‐valued observer, fault isolation (FI) is performed by set manipulations, and fault‐tolerant control is carried out through the design of a robust model predictive control law. In this paper, a set‐valued observer is used to passively complete the fault detection task, while FI is actively performed by making use of the constraint‐handling capability of robust model predictive control. The set‐valued observer is chosen to implement fault detection and isolation (FDI) because of its simple mathematical structure that is not affected by the type of faults such as sensor, actuator, and system‐structural faults. This means that only one set‐valued observer is needed to monitor all considered actuator and sensor statuses (health and fault) and to carry out the fault detection and isolation task instead of using a bank of observers (each observer matching a health/fault status). Furthermore, in the proposed scheme, the advantage of robust model predictive control is that it can effectively deal with system constraints, disturbances, and noises and allow to implement an active FI strategy, which can improve FI sensitivity when compared with the passive FI methods. Finally, a case study based on the well‐known two‐tank system is used to illustrate the effectiveness of the proposed fault‐tolerant model predictive control scheme.

On the temperature dependence of dual‐junction laser power converters
Authors: Reichmuth S. Kasimir , Helmers Henning , Philipps Simon P. , Schachtner Michael , Siefer Gerald , Bett Andreas W. 
Published: October 2016

AbstractDual‐junction GaAs laser power converters optimized for one monochromatic wavelength are presented, and their temperature dependence is experimentally evaluated. External quantum efficiency and irradiance‐dependent current–voltage measurements (10 to 104 W/cm2) under monochromatic laser light (809 nm) have been undertaken to quantify temperature‐ and irradiance‐dependent effects on the performance. The temperature dependence of the current matching of the two subcells, caused by the temperature‐dependent absorbance, is quantified. Losses in performance due to variations in operating temperature for different power‐by‐light applications are calculated to be between 16.2% and 21.0%. Future potential enhancements in cell performance are discussed. For elevated temperatures, super‐linear behavior of the spectral response with increasing irradiance is observed, which is attributed to effective luminescent coupling from the top to the bottom subcell as the device becomes more radiative limited. For low temperatures, where the bottom cell is overproducing, no dependence on irradiance is found, which shows the influence of photon transport losses to the substrate. © 2016 The Authors.

Glass transition in single poly(ethylene oxide) chain: A molecular dynamics simulation study
Authors: Wu Chaofu 
Published: October 2016

ABSTRACTLocal dynamics of single poly(ethylene oxide) chain in various environments (bulk, film, and isolated systems) has been characterized by the reorientation functions of various backbone bond vectors. Within any observation time, the variations of these reorientation functions with the temperature can be well described by the Kohlrausch−Williams−Watts (KWW) like equation, in which the fitted temperature parameter is identified as the glass transition temperature (Tg). The so‐obtained Tg for that polymer faithfully reveals the effects of the observation time, chain flexibility and vector range on the local dynamics. Furthermore, it is found that the KWW like relation is also applicable to the temperature‐dependence of the fraction of frozen atoms or torsions defined by the trajectory radii of gyration or the conformational transitions. Consequently, different motions lead to different values of Tg for the same system. Despite all, the consistent trend can be yielded, namely, Tg (bulk) > Tg (film) > Tg (isolated), which captures the effects of free surfaces on enhanced dynamics. In addition, dynamics heterogeneity in the systems can be quantitatively revealed. The newly proposed method holds a bright promise to predict the Tg values of complex polymers especially for comparisons. © 2016 Wiley Periodicals, Inc. J. Polym. Sci., Part B: Polym.

AbstractObjectiveTo compare in a multicenter randomized controlled trial the benefits in terms of anxiety regulation of a 15‐session single‐component group intervention (SGI) based on support with those of a 15‐session multiple‐component structured manualized group intervention (MGI) combining support with cognitive‐behavioral and hypnosis components.MethodsPatients with nonmetastatic breast cancer were randomly assigned at the beginning of the survivorship period to the SGI (n = 83) or MGI (n = 87). Anxiety regulation was assessed, before and after group interventions, through an anxiety regulation task designed to assess their ability to regulate anxiety psychologically (anxiety levels) and physiologically (heart rates). Questionnaires were used to assess psychological distress, everyday anxiety regulation, and fear of recurrence. Group allocation was computer generated and concealed till baseline completion.ResultsCompared with patients in the SGI group (n = 77), patients attending the MGI group (n = 82) showed significantly reduced anxiety after a self‐relaxation exercise (P = .006) and after exposure to anxiety triggers (P = .013) and reduced heart rates at different time points throughout the task (P = .001 to P = .047). The MGI participants also reported better everyday anxiety regulation (P = .005), greater use of fear of recurrence–related coping strategies (P = .022), and greater reduction in fear of recurrence–related psychological distress (P = .017) compared with the SGI group.ConclusionsThis study shows that an MGI combining support with cognitive‐behavioral techniques and hypnosis is more effective than an SGI based only on support in improving anxiety regulation in patients with breast cancer.
