Congestion‐aware message forwarding in delay tolerant networks: a community perspective
Authors: Wei Kaimin , Dong Mianxiong , Weng Jian , Shi Guangzhou , Ota Kaoru , Xu Ke 
Published: August 2015

SummaryIn delay tolerant networks, most of the existing message forwarding algorithms prefer to deliver messages to the nodes with a higher popularity or centrality in the hope of maximizing the delivery ratio or minimizing the end‐to‐end delay. This forwarding scheme is prone to cause unfair load distribution and further lead to network congestion, overlooked in the previous work. In this paper, we discuss the network congestion from a community perspective and take it into account the design of message forwarding algorithms. We first put forward a novel distributed community detection approach, which could track the evolution of communities. Based on the identified communities, we develop a congestion avoidance mechanism to divert the load away from the congested areas to the alternative custodians and further present a congestion‐aware message forwarding algorithm where messages can avoid being transmitted to the congested nodes. We finally evaluate the effectiveness of distributed community detection and congestion‐aware message forwarding through the extensive real‐trace driven simulations.

Hydrophobic Porous Polyketimines for the Capture of CO2
Authors: Xu Chao , Dinka Ermiase , Hedin Niklas 
Published: August 2015

AbstractA new type of porous polymers is presented. Polyketimines (PPKs) were synthesized by condensing 1,3,5‐tris(4‐aminophenyl)benzene with aromatic diketones using p‐toluenesulfonic acid catalyst. They were characterized by infrared spectroscopy and solid‐state 13C{1H} nuclear magnetic resonance spectroscopy, and their porosities were probed through the adsorption of N2 and CO2. The PPKs had low uptakes of N2 (at −196 °C), which was attributed to diffusion limitations and/or a shrinking of the polymer. They had relatively high uptakes of CO2 (at 0 °C; up to 1.26 mmol g−1 at 0.15 bar and 2.99 mmol g−1 at 1 bar), which was related to ultramicropores (6–9 Å). The PPKs had high estimated CO2‐over‐N2 selectivities (30–40 at 0 °C). Studies on the vapor adsorption of water and ethanol showed the PPKs to be moderately hydrophobic and had a high uptake of ethanol at low partial pressures.
Oxidative Nitration of Styrenes for the Recycling of Low‐Concentrated Nitrogen Dioxide in Air
Authors: Hofmann Dagmar , de Salas Cristina , Heinrich Markus R. 
Published: August 2015

AbstractThe oxidative nitration of styrenes in ethyl acetate represents a metal‐free, environmentally friendly, and sustainable technique to recover even low concentrations of NO2 in air. Favorable features are that the product mixture comprising nitroalcohols, nitroketones, and nitro nitrates simplifies at lower concentrations of NO2. Experiments in a miniplant‐type 10 L wet scrubber demonstrated that the recycling technique is well applicable on larger scales at which initial NO2 concentrations of >10 000 ppm were reliably reduced to less than 40 ppm.

Despite diagnostic criteria are currently available for the distinct subtypes of monocytic‐lineage neoplasias, a number of partially overlapping features still remain evident, which may hamper their differential diagnosis. An accurate identification and characterization of monocytic cells is of major relevance for the diagnosis and classification of these neoplasias. In this regard, as compared to other conventional techniques, flow cytometry has shown the highest sensitivity for detection of early monocytic commitment of (normal and neoplastic) bone marrow CD34+ hematopoietic precursors as well as of monocytic aberrations and maturation blockades, which are frequently associated with clonal myeloid disorders.In the present paper we provide basic principles and criteria for multiparameter flow cytometry identification and characterization of bone marrow monocytic cells that contribute to an improved diagnostic and classification of monocytic lineage‐associated acute leukemias in clinical settings, particularly when using the EuroFlow antibody panels. © 2015 International Clinical Cytometry Society

ABSTRACTObjectiveTo examine differences in parent feeding behaviors and general parenting of overweight children with and without loss of control (LOC) eating.MethodOne‐hundred‐and‐eighteen overweight and obese children (10.40 ± 1.35 years; 53% female; 52% Caucasian; BMI‐z: 2.06 ± 0.39) and their parents (42.42 ± 6.20 years; 91% female; 70% Caucasian; BMI: 31.74 ± 6.96 kg/m2) were seen at a baseline assessment visit for a behavioral intervention that targeted overeating. The Eating Disorder Examination, adapted for children (ChEDE) was administered to assess for LOC eating. Parents completed the Parental Feeding Styles Questionnaire (PFSQ) and the Child Feeding Questionnaire (CFQ) to assess parent feeding styles and behaviors. Children also completed a self‐report measure of general parenting (Child Report of Parent Behavior Inventory, CRPBI‐30).ResultsForty‐three children (36.40%) reported at least one LOC eating episode in the month prior to assessment. Parents who reported greater restriction and higher levels of pressure to eat were more likely to have children that reported LOC eating (ps < 0.05). Parents who utilized more instrumental feeding and prompting/encouragement to eat techniques were less likely to have children that reported LOC eating (ps < 0.05). Child‐reported parenting behaviors were unrelated to child LOC eating (ps > 0.05).DiscussionParent feeding styles and behaviors appear to be differentially and uniquely related to LOC eating in treatment‐seeking overweight and obese children. Future research is needed to determine if implementing interventions that target parent feeding behaviors may reduce LOC eating, prevent full‐syndrome eating disorders, and reduce weight gain in youth. © 2015 Wiley Periodicals, Inc.

Baiting improvesCPUEin nine‐spined stickleback (Pungitius pungitius) minnow trap fishery
Authors: Merilä Juha 
Published: August 2015

AbstractWhether or not baiting influences stickleback catch per unit effort (CPUE) remains a matter of debate among stickleback researchers: While the opinions about the impact of baiting onCPUEdiffer, supporting quantitative data are scarce. The effect of baiting and trap type on nine‐spined stickleback (Pungitius pungitius)CPUEwas studied in a field experiment conducted over four consecutive days in a small pond in northeastern Finland. The results show that baited traps yielded better (meanCPUE = 1.24 fish/trap/d) catches than unbaited traps (meanCPUE = 0.66); however, there were also differences inCPUEdepending on the type of collapsible trap that was used. The trap type effect onCPUEseemed to differ among age classes – the finer meshed trap caught more young‐of‐the‐year fish than the coarse‐meshed one, whereas the opposite was true for the older and larger individuals. The results agree with those of an earlier more restricted study conducted in the same locality: Together, these results provide strong evidence for the positive impact of baiting on nine‐spined sticklebackCPUE.

Published: August 2015

AbstractAboveground plant performance is strongly influenced by belowground microorganisms, some of which are pathogenic and have negative effects, while others, such as nitrogen‐fixing bacteria and arbuscular mycorrhizal fungi, usually have positive effects. Recent research revealed that belowground interactions between plants and functionally distinct groups of microorganisms cascade up to aboveground plant associates such as herbivores and their natural enemies. However, while functionally distinct belowground microorganisms commonly co‐occur in the rhizosphere, their combined effects, and relative contributions, respectively, on performance of aboveground plant‐associated organisms are virtually unexplored. Here, we scrutinized and disentangled the effects of free‐living nitrogen‐fixing (diazotrophic) bacteriaAzotobacter chroococcum(DB) and arbuscular mycorrhizal fungiGlomus mosseae(AMF) on host plant choice and reproduction of the herbivorous two‐spotted spider miteTetranychus urticaeon common bean plantsPhaseolus vulgaris. Additionally, we assessed plant growth, andAMFandDBoccurrence and density as affected by each other. BothAMFalone andDBalone increased spider mite reproduction to similar levels, as compared to the control, and exerted additive effects under co‐occurrence. These effects were similarly apparent in host plant choice, that is, the mites preferred leaves from plants with bothAMFandDBto plants withAMForDBto plants grown withoutAMFandDB.DB, which also act asAMFhelper bacteria, enhanced root colonization byAMF, whereasAMFdid not affectDBabundance.AMFbut notDBincreased growth of reproductive plant tissue and seed production, respectively. BothAMFandDBincreased the biomass of vegetative aboveground plant tissue. Our study breaks new ground in multitrophic belowground–aboveground research by providing first insights into the fitness implications of plant‐mediated interactions between interrelated belowground fungi–bacteria and aboveground herbivores.
A Comparison of Electric Power Smoothing Control Methods for Distributed Generation Systems
Authors: Kanehira Tomoyuki , Takahashi Akiko , Imai Jun , Funabiki Shigeyuki 
Published: August 2015

SUMMARYRenewable forms of energy such as solar energy have attracted attention as alternative sources of fossil fuel. The output power of photovoltaic generation systems changes steeply. Changes in output power have an effect on the electric power quality of the power system. For that reason, a system which can smooth fluctuations of output power is required. In this paper, the moving average, modified moving average, single exponential smoothing, and double exponential smoothing methods are applied to electric power smoothing control schemes for distributed generation systems with photovoltaic generation. The reduction rate of power fluctuations and the maximum stored energy of electric double layer capacitors are adopted as system evaluation measures. To confirm the effectiveness of the power smoothing control methods, a distributed generation power system with photovoltaic generation systems is simulated with the power electronics circuit simulation software PSIM. The methods are then compared by evaluating the reduction in the capacity of electric double layer capacitors without loss in the power smoothing effect.
Power Generation Experiments with a High Temperature Inert Gas Plasma Faraday Type MHD Generator
Authors: Tanaka Manabu , Murakami Tomoyuki , Okuno Yoshihiro 
Published: August 2015

SUMMARYMHD power generation experiments have been conducted by using a single‐pulsed shock‐tunnel facility, where a high‐temperature inert gas (pure argon) at a fixed total temperature of 9000 K is introduced into a linear Faraday generator without seeding. The fluctuations in the output power and light emission from the plasma are found to be small, and the pure inert gas plasma seems to be rather consistently free of ionization instability. The output power is improved by increasing the magnetic flux density in near‐quadric fashion and the enthalpy extraction ratio does not depend on the inlet total pressure (11.2% to 12.9% for 0.063 MPa to 0.105 MPa). The generator performance obtained is competitive with or superior to that of existing seed plasma MHD generators.
A numerical model for the dynamic analysis of inclined pile groups
Authors: Dezi Francesca , Carbonari Sandro , Morici Michele 
Published: August 2015

SummaryThe paper presents a numerical model for the dynamic analysis of pile groups with inclined piles in horizontally layered soil deposits. Piles are modelled with Euler–Bernoulli beams, while the soil is supposed to be constituted by independent infinite viscoelastic horizontal layers. The pile–soil–pile interaction as well as the hysteretic and geometric damping is taken into account by means of two‐dimensional elastodynamic Green's functions. Piles cap is considered by introducing a rigid constraint; the condensation of the problem permits a consistent derivation of both the dynamic impedance matrix of the soil–foundation system and the foundation input motion. These quantities are those used to perform inertial soil–structure interaction analyses in the framework of the substructure approach. Furthermore, the model allows evaluating the kinematic stress resultants in piles resulting from waves propagating in the soil deposit, taking into account the pile–soil–pile interactions. The model validation is carried out by performing accuracy analyses and comparing results in terms of dynamic impedance functions, kinematic response parameters and pile stress resultants, with those furnished by 3D refined finite element models. To this purpose, classical elastodynamic solutions are adopted to define the soil–pile interaction problem. The model results in low computational demands without significant loss of precision, compared with more rigorous approaches or refined finite element models. Copyright © 2015 John Wiley & Sons, Ltd.

Published: August 2015

ABSTRACTIn this work, we propose a single nucleotide polymorphism (SNP) set association test for censored phenotypes in the presence of a family‐based design. The proposed test is valid for both common and rare variants. A proportional hazards Cox model is specified for the marginal distribution of the trait and the familial dependence is modeled via a Gaussian copula. Censored values are treated as partially missing data and a multiple imputation procedure is proposed in order to compute the test statistics. The P‐value is then deduced analytically. The finite‐sample empirical properties of the proposed method are evaluated and compared to existing competitors by simulations and its use is illustrated using a breast cancer data set from the Consortium of Investigators of Modifiers of BRCA1 and BRCA2.

Published: August 2015

AbstractReactive transport modeling plays a critical role in predicting and quantifying impacts of potential CO2 leakage into aquifers at geological carbon sequestration sites. However, a numerical approach generally requires significant computation. This study presents a semi‐analytical approach to reactive transport of CO2 leakage into an aquifer through decoupling transport equations of reactive aqueous species with algebraic manipulation and then solving the algebraic equation sets representing the mass action law of geochemical reactions with the Newton‐Raphson method. The semi‐analytical approach was implemented in a simulation tool, SASCO2M, and verified against a numerical approach for 2‐D synthetic cases. Verification shows that the semi‐analytical approach matched reasonably well the results simulated with the numerical approach. The semi‐analytical approach was applied to simulate pulse‐like CO2 release tests which were used to demonstrate CO2 leakage detection in a shallow aquifer. The semi‐analytical approach reproduced the overall trends of groundwater pH, dissolved inorganic carbon, alkalinity, and concentrations of Ca and Br observed in the testing well. The semi‐analytical approach was further applied to assess the efficiency of a groundwater monitoring network for CO2 leakage detection in a shallow aquifer at a CO2‐enhanced oil recovery site. This study demonstrates that the semi‐analytical approach is simple and efficient and can be followed as a strategic procedure for assessing risks of CO2 leakage on groundwater quality and efficiency of groundwater monitoring networks for leakage detection at geological CO2 sequestration sites. © 2015 Society of Chemical Industry and John Wiley & Sons, Ltd

Published: August 2015

ObjectivesDepression is a common comorbidity of chronic obstructive pulmonary disease (COPD) and is associated with increased exacerbations, healthcare utilization, and mortality. Among Medicare beneficiaries newly diagnosed with COPD, the objectives of this study were to (1) estimate the rate of new episodes of depression and (2) identify factors associated with depression.MethodsWe identified beneficiaries with a first diagnosis of COPD during 2006–2012 using a 5% random sample of Medicare administrative claims data by searching for ICD‐9‐CM codes 490, 491.x, 492.x, 494.x, or 496. We identified episodes of depression using ICD‐9‐CM codes 296.2x, 296.3x, and 311.xx. We calculated incidence rates and their 95% confidence intervals (95% CI) and used a discrete time analysis to identify factors associated with development of depression.ResultsBetween 2006 and 2012, 125,348 beneficiaries meeting inclusion criteria were newly diagnosed with COPD. Twenty‐three percent developed depression following COPD diagnosis. The annualized incidence rate of depression per 100 beneficiaries following COPD diagnosis was 9.4 (95% CI 9.3, 9.5). Rates were highest in the first 2 months following COPD diagnosis. COPD diagnosis was associated with increased risk of depression (risk ratio 1.76; 95% CI 1.73, 1.79) as were COPD‐related hospitalizations (risk ratio 4.59; 95% CI 4.09, 5.15), a measure of COPD severity.ConclusionsDiagnosis of COPD increases the risk of depression. This study will aid in the allocation of resources to monitor and provide support for individuals with COPD at high risk of developing depression. Copyright © 2015 John Wiley & Sons, Ltd.

Published: August 2015

ObjectiveDepression in Parkinson disease (PD) is a common problem that worsens quality of life and causes disability. However, little is known about the longitudinal impact of depression on disability in PD. This study examined the association between disability and DSM‐IV‐TR depression status across six years.MethodsLongitudinal cohort study with assessments at study entry, year two, four, and six conducted in the Morris K. Udall Parkinson Disease Research Center. Recruitment totaled 137 adult men and women with idiopathic PD in which up to six years of data on demographic, motor, and non‐motor variables was collected. Movement disorder specialists used the structured interview for DSM‐IV‐TR depressive disorders and the Northwestern Disability Scale to assess depression and disability. A generalized linear mixed model was fitted with Northwestern Disability Scale score as the dependent variable to determine the effect of baseline depression status on disability.ResultsA total of 43 participants were depressed at baseline compared to 94 without depression. Depressed participants were more likely to be female, were less educated, were less likely to take dopamine agonists, and more likely to have motor fluctuations. Controlling for these variables, symptomatic depression predicted greater disability compared to both never depressed (p = 0.0133) and remitted depression (p = 0.0009). Disability associated with symptomatic depression at baseline was greater over the entire six‐year period compared to participants with remitted depressive episodes or who were never depressed.ConclusionsPersisting depression is associated with a long‐term adverse impact on daily functioning in PD. Adequate treatment or spontaneous remission of depression improves ADL function. Copyright © 2015 John Wiley & Sons, Ltd.
Optimization and characterization of injectable chitosan‐iodixanol‐based hydrogels for the embolization of blood vessels
Authors: Fatimi Ahmed , Zehtabi Fatemeh , Lerouge Sophie 
Published: August 2015

AbstractChitosan‐thermosensitive hydrogels present interesting features for the embolization of blood vessels, but need to be better characterized and optimized. Chitosan polymer (degree of deacetylation (DDA) of 94%) was purified and combined with Visipaque (VIS), a nonionic isotonic contrast agent composed of iodixanol. A beta‐glycerolphosphate (βGP) solution was then added to induce gelation at body temperature. The gelation process was monitored by rheometry, measuring the evolution of the sample storage (G′) and loss (G″) moduli as a function of VIS and βGP concentration. Adding VIS significantly slowed down gelation kinetics, but a 12% and higher βGP concentration provided a radiopaque solution, which at 37°C, gels immediately. A custom‐made in vitro embolization bench test was developed to assess the gel's occlusive properties, and its injectability through a small diameter catheter was verified. Results show that the short‐term occlusive properties of the gel were insufficient when using a βGP concentration of 12% w/v (about 0.4M), but that increasing the βGP to 20% (0.6M) allowed an acceleration of the gelation and the immediate blocking of flow above physiological pressure. The contrast agent was rapidly released in solution, such that it would not interfere with future follow‐up imaging. In accordance with the literature data, the cytotoxicity of gel extracts increased with βGP concentration and to a lesser extent with VIS concentration. Preliminary in vivo testing showed easy injection by catheter and good visibility under fluoroscopy. These results suggest that radiopaque CH/βGP20%/VIS hydrogels present significant potential as embolizing agents for blood vessels and aneurysms. © 2015 Wiley Periodicals, Inc.

ABSTRACTCover illustration. The teleost gill forms an extensive, semipermeable barrier that must tolerate intimate contact with the surrounding environment and be able to protect the body from external pathogens. The recent discovery of the interbranchial lymphoid tissue has initiated an anatomical and functional investigation of the lymphoid tissue of the salmonid gill. In this issue of the Journal of Morphology, Dalum et al. (pp. 1075–1088) report about the novel interbranchial lymphoid tissue of Atlantic salmon. The cover image shows the interbranchial lymphoid tissue with its distal distribution in a gill filament presented with immune‐labelled T cells. It represents an evolutionary structure unparalleled by any other known vertebrate lymphoid tissue.
