Neurofeedback Against Binge Eating: A Randomized Controlled Trial in a Female Subclinical Threshold Sample
Authors: Schmidt Jennifer , Martin Alexandra 
Published: April 2016

AbstractBrain‐directed treatment techniques, such as neurofeedback, have recently been proposed as adjuncts in the treatment of eating disorders to improve therapeutic outcomes. In line with this recommendation, a cue exposure EEG‐neurofeedback protocol was developed. The present study aimed at the evaluation of the specific efficacy of neurofeedback to reduce subjective binge eating in a female subthreshold sample. A total of 75 subjects were randomized to EEG‐neurofeedback, mental imagery with a comparable treatment set‐up or a waitlist group. At post‐treatment, only EEG‐neurofeedback led to a reduced frequency of binge eating (p = .015, g = 0.65). The effects remained stable to a 3‐month follow‐up. EEG‐neurofeedback further showed particular beneficial effects on perceived stress and dietary self‐efficacy. Differences in outcomes did not arise from divergent treatment expectations. Because EEG‐neurofeedback showed a specific efficacy, it may be a promising brain‐directed approach that should be tested as a treatment adjunct in clinical groups with binge eating.

Validating Policy‐Induced Economic Change Using Sequential General Equilibrium SAMs
Authors: Cardenete M. Alejandro , Lima M. Carmen , Sancho Ferran 
Published: April 2016

AbstractWe present a novel sequential approach that explores the capacity of Computable general equilibrium (CGE) models to track down policy‐induced economic changes and their ability to generate contrastable data. We use an empirical Social accounting matrix (SAM) of the region of Andalusia, in the south of Spain, to construct an initial CGE model. This model is then perturbed with a set of policy shocks related to EU Structural Funds invested into Andalusia. These shocks are accompanied by some parameter adjustments that pick up the main external changes not explained by the model. We generate a sequence of model‐produced virtual SAMs. We then compare the last virtual SAM in the sequence with a new available empirical SAM. This allows us to check relatedness, for the same year, between the model produced and the empirical SAMs. The results show a good fit to the empirical data, providing further support to the CGE modelling tool.

Spatio‐temporal variability of water and energy fluxes – a case study for a mesoscale catchment in pre‐alpine environment
Authors: Hingerl Luitpold , Kunstmann Harald , Wagner Sven , Mauder Matthias , Bliefernicht Jan , Rigon Riccardo 
Published: April 2016

AbstractWater and energy fluxes at and between the land surface, the subsurface and the atmosphere are inextricably linked over all spatio‐temporal scales. Our research focuses on the joint analysis of both water and energy fluxes in a pre‐alpine catchment (55 km2) in southern Germany, which is part of the Terrestrial Environmental Observatories (TERENO). We use a novel three‐dimensional, physically based and distributed modelling approach to reproduce both observed streamflow as an integral measure for water fluxes and heat flux and soil temperature measurements at an observation location over a period of 2 years. While heat fluxes are often used for comparison of the simulations of one‐dimensional land surface models, they are rarely used for additional validation of physically based and distributed hydrological modelling approaches. The spatio‐temporal variability of the water and energy balance components and their partitioning for dominant land use types of the study region are investigated. The model shows good performance for simulating daily streamflow (Nash–Sutcliffe efficiency > 0.75). Albeit only streamflow measurements are used for calibration, the simulations of hourly heat fluxes and soil temperatures at the observation site also show a good performance, particularly during summer. A limitation of the model is the simulation of temperature‐driven heat fluxes during winter, when the soil is covered by snow. An analysis of the simulated spatial fields reveals heat flux patterns that reflect the distribution of the land use and soil types of the catchment. The water and energy partitioning is characterized by a strong seasonal cycle and shows clear differences between the selected land use types.

ObjectivesTo evaluate the effect of Pringle maneuver time on tumor recurrence following liver resection in patients with hepatocellular carcinoma (HCC).MethodsIn this single‐center study, we retrospectively evaluated the effect of Pringle maneuver time on HCC recurrence over a 10‐year period from 1999 to 2008 using a Cox regression analysis.ResultsThis study enrolled a total of 2,368 patients. A Pringle maneuver time of 15 min was associated with HCC recurrence (log likelihood ratio test, P = 0.001). A Pringle maneuver time less than 15 min was not a significant risk factor for HCC recurrence (hazard ratio, HR = 0.97, P = 0.708). However, a Pringle maneuver time greater than 15 min was an independent predictor of HCC recurrence (HR = 1.41, P < 0.001). The patients who underwent the Pringle maneuver for over 15 min had lower overall survival (OS) and recurrence‐free survival (RFS) than did those who either did not undergo the maneuver or underwent the maneuver for less than 15 min (both P < 0.001).ConclusionsThese results suggest that a longer duration of the Pringle maneuver increases the risk of tumor recurrence in patients with HCC. However, a shorter duration of the Pringle maneuver decreases this risk. J. Surg. Oncol. 2016;114:112–118. © 2016 Wiley Periodicals, Inc.

The European project F3 Factory aims at designing small to medium scale plants consisting of standardized container assemblies for delocalized production of various chemicals. Within the framework of the F3 Factory project, the design of a modular, multiproduct, and continuous plant for manufacturing water‐soluble polymers is addressed. Free radical polymerization in aqueous solution is examined through two industrial cases: polymerization of acrylic acid (AA) in the presence of chain transfer agent (CTA) and copolymerization of AA with one comonomer. A methodology for performing the transition from batch recipes to continuous operations is proposed. Offline and inline monitoring of monomer consumption is achieved using Raman spectroscopy combined with chemometrics. A modular pilot plant meeting the requirements of F3 Factory project is designed and demonstrated at INVITE (Bayer, Leverkusen). The two polymerization processes are successively operated in the same pilot plant separated by an intermediate extensive washing. For each process, several polymer grades are produced by modification of reaction conditions (inlet flow of CTA or reactor temperature). Transition dynamics are characterized using inline monitoring. The flexibility of the modular plant is demonstrated.image

Published: April 2016

ABSTRACTIntroduction: Myasthenia gravis (MG) is a B‐cell–mediated autoimmune disease. B‐cell–activating factor (BAFF) is a major factor in B‐cell development and activation. In this study we investigated serum BAFF levels in MG patients. Methods: We compared the serum BAFF levels of 20 MG patients with gender‐matched healthy controls. We assayed serum concentrations of BAFF and anti‐acetylcholine receptor antibody (AChR) titers. Results: Serum BAFF levels of MG patients with AChR antibodies were significantly higher than those of healthy controls. A significant positive correlation was observed between serum BAFF levels and anti‐AChR antibody titers. BAFF values did not correlate with disease severity. Conclusions: BAFF may play a major role in the pathogenesis of MG, and it may provide a potential target for therapy in patients with MG. Muscle Nerve 54: 1030–1033, 2016

Published: April 2016

AbstractThe porous structure evolution of thermosetting phenolic resin controlled by polymerization induced viscoelastic phase separation from solution was investigated in this work. The ultimate morphology and the evolution of a porous texture for the resol resin/solvent system were characterized by digital camera and optical microscopy. In-situ Fourier transform infrared spectroscopy and a rheological method were used to trace the curing reaction of the resol resin/solvent system. The impacts of solvent content and curing temperature on the foaming behavior were quantitatively and systematically investigated. Based on the relationship between the morphology evolution and curing dynamics, the foaming mechanism of the polymerization induced viscoelastic phase separation was elucidated. The present work provides new insight into the foaming mechanism of thermosetting materials and may be helpful for morphological control in the preparation of lightweight porous phenolic material. © 2016 Society of Chemical Industry
Effects of graphene oxide on the formation, structure and properties of bionanocomposite films made from wheat gluten with chitosan
Authors: Lee Dan Bi , Kim Dong Won , Shchipunov Yury , Ha Chang‐Sik 
Published: April 2016

AbstractGraphene oxide (GO) was combined with wheat gluten (WG) and chitosan (CS) to prepare bionanocomposite films using a casting method. The films were characterized using a variety of techniques, including scanning and transmission electron microscopies, atomic force microscopy, X‐ray diffraction, thermogravimetric analysis, Fourier transform infrared spectroscopy, mechanical testing, water swelling, oxygen permeability and contact angle measurements, to determine the effects of GO on the formation, structure and properties of the bionanocomposites. Their formation and properties were found to be dependent on the mixing order of the three components. The added GO was found to strengthen the films, as well as to decrease water absorption and oxygen permeability. These effects were attributed to the good dispersion of GO in the WG/CS matrix enabled by hydrogen bonds. The decreased water absorption could be explained by the increased hydrophobicity. The notable improvement of the properties of the WG/CS films as a result of GO addition makes the films suitable as packaging materials. © 2016 Society of Chemical Industry
Atmospheric‐pressure photoelectron emission from H‐terminated and amino‐terminated diamond
Authors: Hamers Robert J. , Bandy Jason 
Published: April 2016

We report investigations of the ultraviolet‐induced emission of electrons from diamond into air, argon, and SF6 gases at atmospheric pressure. Although diamond has long been known to be a facile emitter of electrons in vacuum, the present results show that H‐terminated and amino‐terminated diamond can also act as emitters of low‐energy electrons into gases at atmospheric pressure. Present results show that emission currents follow the trend Ar > air > SF6. We attribute these differences to the fact that Ar does not form stable anions and the emitted electrons remain as free electrons with very low effective mass, while electrons in air form O2− and electrons in SF6 form SF6− anions. The observed trends are consistent with trends reported in ion mobility measurements.Photoemission of electrons from diamond into argon gas at atmospheric pressure.
Particle-resolved direct numerical simulation of homogeneous isotropic turbulence modified by small fixed spheres
Authors: Vreman A. W. 
Published: April 2016

A statistically stationary homogeneous isotropic turbulent flow modified by 64 small fixed non-Stokesian spherical particles is considered. The particle diameter is approximately twice the Kolmogorov length scale, while the particle volume fraction is 0.001. The Taylor Reynolds number of the corresponding unladen flow is 32. The particle-laden flow has been obtained by a direct numerical simulation based on a discretization of the incompressible Navier–Stokes equations on 64 spherical grids overset on a Cartesian grid. The global (space- and time-averaged) turbulence kinetic energy is attenuated by approximately 9 %, which is less than expected. The turbulence dissipation rate on the surfaces of the particles is enhanced by two orders of magnitude. More than 5 % of the total dissipation occurs in only 0.1 % of the flow domain. The budget of the turbulence kinetic energy has been computed, as a function of the distance to the nearest particle centre. The budget illustrates how energy relatively far away from particles is transported towards the surfaces of the particles, where it is dissipated by the (locally enhanced) turbulence dissipation rate. The energy flux towards the particles is dominated by turbulent transport relatively far away from particles, by viscous diffusion very close to the particles, and by pressure diffusion in a significant region in between. The skewness and flatness factors of the pressure, velocity and velocity gradient have also been computed. The global flatness factor of the longitudinal velocity gradient, which characterizes the intermittency of small scales, is enhanced by a factor of six. In addition, several point-particle simulations based on the Schiller–Naumann drag correlation have been performed. A posteriori tests of the point-particle simulations, comparisons in which the particle-resolved results are regarded as the standard, show that, in this case, the point-particle model captures both the turbulence attenuation and the fraction of the turbulence dissipation rate due to particles reasonably well, provided the (arbitrary) size of the fluid volume over which each particle force is distributed is suitably chosen.
Feeding ecology and habitat preferences of top predators from two Miocene carnivore-rich assemblages

Published: April 2016

AbstractCarnivore-rich fossil sites are uncommon in the fossil record and, accordingly, provide valuable opportunities to study predators from vantages that are rarely applied to ancient faunas. Through stable isotopes of carbon and a Bayesian mixing model, we analyze time-successive (nearly contemporaneous), late Miocene carnivoran populations from two fossil sites (Batallones-1 and Batallones-3) from central Spain. Stable isotopes of carbon in tooth enamel provide a reliable and direct methodology to track ancient diets. These two carnivoran-dominated fossil sites display differences in the composition and abundance of the carnivoran species, with some species present at both sites and some present only at one site. This disparity has been interpreted as the consequence of habitat differences between Batallones-1, the older site, and Batallones-3, the younger site. However, carbon isotope values of carnivore and herbivore tooth enamel suggest a common habitat of C3 woodland originally present at both sites. The differences in the carnivoran faunas rather may be the consequence of the dynamics of species entrance and exit from the Madrid Basin during the time elapsed between Batallones-1 and Batallones-3 and changes in population densities due to biotic factors. We infer higher levels of interspecific competition in Batallones-3 than in Batallones-1 because of the larger number of similar-sized, sympatric predators; the clear overlap in their δ13C values (except for the amphicyonid Magericyon anceps); and similarity of their preferred prey: the hipparionine horses. Finally, carbon stable isotopic composition of Indarctos arctoides teeth implies that this ursid was a carnivorous omnivore rather than a herbivorous omnivore. This work demonstrates the insights that stable isotopes can provide in characterizing the feeding ecology and trophic interactions of ancient carnivoran taxa.
The evolution of growth patterns in mammalian versus nonmammalian cynodonts
Authors: O’Meara Rachel N. , Asher Robert J. 
Published: April 2016

AbstractOne of the major evolutionary transitions of the mammaliaform lineage was the origin of a typically mammalian pattern of growth. This is characterized by rapid juvenile growth followed by abrupt cessation of growth at adult size and may be linked with other important mammaliaform apomorphies of dental replacement and morphology. Investigation of growth patterns in the tritylodontid cynodontOligokyphusand the basal mammaliaformMorganucodonprovides insight into this crucial transition. We collected mandibular depth measurements from large samples ofMorganucodonandOligokyphusand constructed distributions of mandibular depth versus frequency for each species. These were compared with distributions from species from three different growth classes of extant amniote: testudines + crocodilians, mammals + birds, and lepidosaurs. Discriminant function analysis was used to differentiate between known growth classes by using different combinations of three measures of mandibular depth distribution shape (skew, kurtosis, and coefficient of variation) as proxies for different juvenile and adult growth patterns. Classification of the fossil species showed thatMorganucodonclosely resembled extant placental mammals in having rapid juvenile growth followed by truncated, determinate adult growth.Oligokyphusshowed intermediate growth patterns, with more extended adult growth patterns thanMorganucodonand slightly slower juvenile growth. This suggests a gradual evolution of mammalian growth patterns across the cynodont to mammaliaform transition, possibly with the origin of rapid juvenile growth preceding that of truncated, determinate adult growth. In turn, acquisition of both these aspects of mammalian growth was likely necessary for the evolution of diphyodont tooth replacement in the mammaliaform lineage.

AbstractAutomation of dietary assessment can reduce limitations of established methodologies, by alleviating participant and researcher burden. Designed as a research tool, the electronic Dietary Intake Assessment (e-DIA) is a food record in mobile phone application format. The present study aimed to examine the relative validity of the e-DIA with the 24-h recall method to estimate intake of food groups. A sample of eighty university students aged 19–24 years recorded 5 d of e-DIA and 3 d of recall within this 5-d period. The three matching days of dietary data were used for analysis. Food intake data were disaggregated and apportioned to one of eight food groups. Median intakes of food groups were similar between the methods, and strong correlations were found (mean: 0·79, range: 0·69–0·88). Cross-classification by tertiles produced a high level of exact agreement (mean: 71 %, range: 65–75 %), and weightedκvalues were moderate to good (range: 0·54–0·71). Although mean differences (e-DIA–recall) were small (range: –13 to 23 g), limits of agreement (LOA) were relatively large (e.g. for vegetables, mean difference: –4 g, LOA: –159 to 151 g). The Bland–Altman plots showed robust agreement, with minimum bias. This analysis supports the use of e-DIA as an alternative to the repeated 24-h recall method for ranking individuals’ food group intake.

AbstractThe International Clearinghouse for Birth Defects, Surveillance and Research reports a rise in the prevalence rate of spina bifida in Japan. We determined first-trimester folate status of Hokkaido women and identified potential predictors. Participants were 15 266 pregnant women of the Hokkaido Study on Environment and Children’s Health Cohort. Data were extracted from self-reported questionnaires and biochemical assay results. Demographic determinants of low folate status were younger maternal age (adjusted OR (AOR) 1·48; 95 % CI 1·32, 1·66), lower educational level (AOR 1·27; 95 % CI 1·17, 1·39) and lower annual income (AOR 1·11; 95 % CI 1·01, 1·22). Plasma cotinine concentrations of 1·19–65·21 nmol/l increased the risk of low folate status (AOR 1·20; 95 % CI 1·10, 1·31) and concentrations >65·21 nmol/l further increased the risk (AOR 1·91; 95 % CI 1·70, 2·14). The most favourable predictor was use of folic acid (FA) supplements (AOR 0·19; 95 % CI 0·17, 0·22). Certain socio-demographic factors influence folate status among pregnant Japanese women. Modifiable negative and positive predictors were active and passive tobacco smoking and use of FA supplements. Avoiding both active and passive tobacco smoking and using FA supplements could improve the folate status of Japanese women.
Detrital zircon U–Pb ages and Hf isotopic composition of the Ordovician Duguer quartz schist, central Tibetan Plateau: constraints on tectonic affinity and sedimentary source regions

Published: April 2016

AbstractMany previous studies have investigated the late Palaeozoic ophiolites, migmatites and high-pressure metamorphic belts of the Tibetan Plateau, whereas the early Palaeozoic evolution of the regions is relatively poorly understood. Lower Palaeozoic strata, including the Duguer quartz schist, occur in the Himalaya, Lhasa and South Qiangtang terranes of the Tibetan Plateau. In this study, we report the depositional age and sedimentary provenance of the Duguer quartz schist of the central South Qiangtang terrane, which enables us to interpret the tectonic affinity of the terrane. We obtained U–Pb ages, trace-element compositions and Hf isotopic data from zircons from the Duguer quartz schist. A total of 162 U–Pb analyses of detrital zircons from the schist yielded two pronounced age peaks at c. 600 Ma and c. 960 Ma. These results indicate that the provenance of the Duguer quartz schist is India Gondwana or the terranes that share an affinity with India Gondwana in the Tibetan Plateau, which include the South Qiangtang and Himalaya terranes. Detrital zircon crystals show large variations in Hf isotope compositions, with εHf(t), TDM and TDMC values of −52.5 to 13.2, 900–3300 Ma and 1010–4240 Ma, respectively. This suggests that the source area for the Duguer quartz schist included Precambrian rocks and, more specifically, Pan-African and Grenville–Jinning crustal material. During Pan-African and Grenville–Jinning events, crustal recycling and the addition of mantle material occurred in the source regions of the quartz schist, when the South Qiangtang, Lhasa and Himalaya terranes were all part of the northern margin of Gondwana.
