Mobile agent itinerary planning for WSN data fusion: considering multiple sinks and heterogeneous networks
Authors: Gavalas Damianos , Venetis Ioannis E. , Konstantopoulos Charalampos , Pantziou Grammati 
Published: September 2016

SummaryMobile agent (MA)‐based middleware has been thoroughly investigated in the past few years as a means to address the efficiency, scalability, and reliability issues of data fusion applications on wireless sensor networks. Deriving an efficient itinerary for each MA to follow is of high importance, because itineraries determine to a large extent the overall performance of data fusion tasks. In this article, we present a novel algorithmic approach for efficient itinerary planning of MA objects undertaking data fusion tasks. We adopt a method based on iterated local search to construct the itineraries (ie, visiting sequences of source nodes) assigned to multiple traveling MAs. We apply alternative optimization criteria which aim either at minimizing the overall energy expenditure over all derived MA itineraries or prolonging the network lifetime. Furthermore, we propose algorithmic solutions for 2 realistic settings which have not been investigated in the past: firstly, the employment of multiple sinks that share the responsibility of MA‐based data fusion tasks across the sensor field, and secondly, the consideration of heterogeneous sensor networks comprising nodes powerful enough to host the runtime environment required to execute MA code as well as “ordinary” nodes which lack these resources. Simulation tests verify the performance gain attained by our algorithmic methods against alternative itinerary planning approaches which involve multiple MAs. Copyright © 2016 John Wiley & Sons, Ltd.
A structural and functional comparison of gap junction channels composed of connexins and innexins
Authors: Skerrett I. Martha , Williams Jamal B. 
Published: September 2016

ABSTRACTMethods such as electron microscopy and electrophysiology led to the understanding that gap junctions were dense arrays of channels connecting the intracellular environments within almost all animal tissues. The characteristics of gap junctions were remarkably similar in preparations from phylogenetically diverse animals such as cnidarians and chordates. Although few studies directly compared them, minor differences were noted between gap junctions of vertebrates and invertebrates. For instance, a slightly wider gap was noted between cells of invertebrates and the spacing between invertebrate channels was generally greater. Connexins were identified as the structural component of vertebrate junctions in the 1980s and innexins as the structural component of pre‐chordate junctions in the 1990s. Despite a lack of similarity in gene sequence, connexins and innexins are remarkably similar. Innexins and connexins have the same membrane topology and form intercellular channels that play a variety of tissue‐ and temporally specific roles. Both protein types oligomerize to form large aqueous channels that allow the passage of ions and small metabolites and are regulated by factors such as pH, calcium, and voltage. Much more is currently known about the structure, function, and structure–function relationships of connexins. However, the innexin field is expanding. Greater knowledge of innexin channels will permit more detailed comparisons with their connexin‐based counterparts, and provide insight into the ubiquitous yet specific roles of gap junctions. © 2016 Wiley Periodicals, Inc.

Fast and Controlled Decorating of Metallic Nanoparticles Using Wall‐jet Configuration
Authors: Alencar Leticia M. , Caneppele Gabriella L. , Martins Cauê A. 
Published: September 2016

AbstractA new method to decorate metallic nanoparticles (NPs) based on the wall‐jet configuration was developed. A homemade wall‐jet amperometric cell coupled to an electronic micropipette was used to decorate Pt NPs with Sb and Sn hydrodynamically through the injection of metallic precursor solutions onto an electrode modified with NPs under applied potential. The method allows the control of the coverage degree (θ) by changing easy handling parameters such as injection flow rate, injected volume and concentration of precursors. The decoration procedure is fast, reproducible, simple and economic, since it only uses a few microlitres of precursors to prepare each electrode composition. It is possible to prepare an average of 1000 electrodes using the same amount of precursors for each one prepared by a conventional method using a typical three‐electrode cell. Sb‐ and Sn‐decorated Pt/C NPs were first evaluated towards diluted glucose electrooxidation in buffer solution. These first insights reveal that the output current density increases with θSb and θSn; Sb‐decorated Pt/C shows the greatest improvement.

Published: September 2016

AbstractCarbon‐coated zinc iron oxides (ZnFe2O4/C) are synthesized by a hydrothermal method and subsequent calcination at three different temperatures. X‐ray diffraction and transmission electron microscopy indicate that the spherical ZnFe2O4/C samples are well‐crystallized and that an amorphous layer of carbon, derived from thermal decomposition of glucose, is deposited on the surface of the ZnFe2O4 samples. The testing results demonstrate that ZnFe2O4/C sintered at 600 °C shows a high reversible capacity of 579 mAh g−1 at a current density of 100 mA g−1 after 100 cycles and good rate capability. This indicates the potential use of ZnFe2O4/C as anode materials for lithium‐ion batteries.

Published: September 2016

SummarySubcortical band heterotopia (SBH) is a disorder of neuronal migration most commonly due to mutations of the Doublecortin (DCX) gene. A range of phenotypes is seen, with most patients having some degree of epilepsy and intellectual disability. Advanced diffusion and structural magnetic resonance imaging (MRI) sequences may be useful in identifying heterotopias and dysplasias of different sizes in drug‐resistant epilepsy. We describe a patient with SBH and drug‐resistant epilepsy and investigate neurite density, neurite dispersion, and diffusion parameters as compared to a healthy control through the use of multiple advanced MRI modalities. Neurite density and dispersion in heterotopia was found to be more similar to white matter than to gray matter. Neurite density and dispersion maps obtained using diffusion imaging may be able to better characterize different subtypes of heterotopia.

AbstractBackgroundDeficits in neuropsychological functioning have consistently been identified in patients with anorexia nervosa (AN). However, little is known on how decision making in AN patients evolves in response to treatment or whether impairments are reversible.MethodAN patients (n = 42) completed the Iowa Gambling Task (IGT) upon admission to a 3‐month day‐hospital treatment programme and at a 1‐year follow‐up. Patient IGT performance was compared to age‐matched controls (n = 46).ResultsAN patients displayed poorer performance on the IGT at admission compared to controls (p < .001). Patients with full remission (n = 31; 73.9%) at the 1‐year follow‐up improved IGT performance (p = 0.007), and scores were similar compared to controls (p = 0.557). AN patients with partial/no remission at follow‐up (n = 11; 26.1%) did not improve IGT scores (p = 0.867).ConclusionsThese findings uphold that enduring remission from AN can reverse decision‐making impairments, and they might be most likely explained by clinical state rather than a trait vulnerability.

Published: September 2016

AbstractChili peppers (Capsicum spp.) may possess antibacterial properties and have potential to be used in foods as antimicrobial. The complete chili pepper extract should be evaluated to determine which compounds are responsible for the antimicrobial activity. Extraction of compounds from the pepper is completed using a solvent. The type of solvent used for extraction influences which compounds are isolated, therefore the best extraction method needs to be determined. The purpose of this study was to identify which solvent is most successful at extracting unknown antibacterial compounds from jalapeño peppers. Fresh jalapeño peppers were chopped, weighed, and blended with a solvent (sterilized hot water, 70% methanol, 95% methanol, 70% ethanol, or 95% ethanol) at a 1:1 ratio (g/g) until the mixture was homogenized, followed by shaking for 15 min. The slurry was centrifuged; supernatant was removed and used for antibacterial testing against Listeria monocytogenes, Escherichia coli O157:H7, and Salmonella enterica. The diameter of growth inhibition was measured and statistically evaluated using ANOVA to determine the extract with the greatest antimicrobial activity. Solvents were tested alone as a control. There was greater bacterial inhibition from extracts created with methanol and ethanol than hot water. Listeria monocytogenes was significantly more susceptible to the extracts than E. coli or Salmonella isolates. Each solvent extract was then analyzed using high‐performance liquid chromatography (HPLC) and fractions (A–G) were collected and used for subsequent disk diffusion analysis against L. monocytogenes. Fractions E and F (eluded between 20 and 30 min) exhibited the most antibacterial activity. There were no differences between solvents used (p = .05). Further investigation into specific compounds within these extracts will be completed in the future.
Controlling of Proton Exchange Membrane Fuel Cell by Model Predictive Controller Based on ANFIS Model
Authors: Karimi M. , Yahyazadeh J. , Rezazade A. 
Published: September 2016

AbstractProton exchange fuel cell is one of the most promising new technologies in electrical energy production. Due to slow dynamic, nonlinearity and dependency of time changing variables of proton exchange membrane fuel cell (PEMFC), its control issue is a challenging problem. In this paper, model predictive controller (MPC) based on the adaptive neuro‐fuzzy interface model of the PEMFC is proposed to control the output voltage. First the adaptive neuro‐fuzzy interference system (ANFIS) model is identified to approximate the dynamic behavior of the PEMFC system with a set of data which are taken from a physical model of a 5 kW PEMFC setup plant. Then the branch‐and‐bound method and the greedy algorithm are used to solve the constrained optimization function of the predictive control problem. The results reveal that the ANFIS model can effectively approximate the dynamic behavior of the PEMFC and the predictive controller based on this model can successfully control the output and satisfy the constraints.
Diagnosing snow accumulation errors in a rain‐snow transitional environment with snow board observations
Authors: Wayand Nicholas E. , Clark Martyn P. , Lundquist Jessica D. 
Published: August 2016

AbstractDiagnosing the source of errors in snow models requires intensive observations, a flexible model framework to test competing hypotheses, and a methodology to systematically test the dominant snow processes. We present a novel process‐based approach to diagnose model errors through an example that focuses on snow accumulation processes (precipitation partitioning, new snow density, and snow compaction). Twelve years of meteorological and snow board measurements were used to identify the main source of model error on each snow accumulation day. Results show that modeled values of new snow density were outside observational uncertainties in 52% of days available for evaluation, while precipitation partitioning and compaction were in error 45% and 16% of the time, respectively. Precipitation partitioning errors mattered more for total winter accumulation during the anomalously warm winter of 2014–2015, when a higher fraction of precipitation fell within the temperature range where partition methods had the largest error. These results demonstrate how isolating individual model processes can identify the primary source(s) of model error, which helps prioritize future research.

ABSTRACTParotoid glands of amphibians are known for the production of several biologically active compounds having pharmacological and toxic effects in mammals. In the present work, a protein fraction obtained from Rhinella schneideri parotoid gland (RsPP) was characterized to study its biological and toxic effects. Rhinella schneideri parotoid secretion is composed of up to 30% (w/w) of soluble proteins. Tandem mass spectrometric analysis of the RsPP identified 104 proteins, including actin, beta‐actin, ribosomal proteins, catalase, galectin, and uncharacterized proteins; however, no peptidases were found, and this result was reinforced by the absence of proteolytic activity. In addition, RsPP did not exhibit pro‐coagulant or antibacterial effects. However, pretreatment of mice with different doses of RsPP intraperitoneally inhibited carrageenan‐induced paw edema and increased tissue myeloperoxidase activity. RsPP also reduced interleukin 1β levels in the peritoneal cavities and cell migration in the peritoneal cavities of an animal model of carrageenan‐induced peritonitis. Subchronic treatment of animals with RsPP for 7 consecutive days did not alter the serum biochemical, renal, or liver parameters. However, a significant reduction in blood leukocyte count was observed. Our results showed that R. schneideri parotoid secretion contains proteins with anti‐inflammatory and slight toxic effects.

Highly Reduced Species Mechanisms for iso‐Cetane Using the Local Self‐Similarity Tabulation Method
Authors: Kourdis Panayotis D. , Bellan Josette 
Published: September 2016

ABSTRACTWe utilize the local self‐similarity tabulation method to drastically downsize the number of species involved in a detailed kinetic mechanism of iso‐cetane. Reduced‐species mechanisms of 20 and 15 species are constructed, out of the 1114 species involved in the detailed mechanism, with a focus on high‐pressure combustion. The performance of the two reduced mechanisms are compared to the detailed one for a lean (ϕ = 0.5), stoichiometric (ϕ = 1.0), and rich (ϕ = 1.5) iso‐cetane/air mixture at initial temperatures of 900 and 1100 K and constant pressures of 20 and 40 bar. Good to very good agreement between the detailed kinetic mechanism and the two highly reduced species mechanisms are demonstrated.
Laser Power Measurement in Confined Spaces
Authors: Klein Rolf , Schwede Harald 
Published: September 2016

AbstractA frequent measurement of the laser beam power ensures successful laser processing. Usually, laser systems have a display for laser power. But this display shows the laser power on the laser output and not the laser power at the processing zone. For material processing, it is important to know the effects of the beam guiding system and the processing head on the transmitted laser power. So a laser power measurement as close as possible to the processing zone is preferable. But in many cases, the accessibility of the processing zone is not given for conventional power sensors due to limited space. To enable a greater degree of flexibility, Primes has developed the laser measurement device Cube which will be described below.
Multi‐Material Processing
Authors: Anstaett Christine , Seidel Christian 
Published: September 2016

AbstractSeveral additive manufacturing technologies are applied in industrial manufacturing today. For instance, laser‐based powder bed fusion of metals (also known as e.g. laser beam melting, selective laser melting) is utilized for serial production in aerospace industry [1]. The main advantage of additive manufacturing technologies is the freedom of design. Hence, functionally optimized parts in terms of lightweight, fluid dynamics etc., can be produced without having an exponential growth in manufacturing costs when increasing geometrical complexity, like it is known from conventional machining. However, predominantly mono‐material processing is commercially available today. This is especially true with regards to laser‐based powder bed fusion of metals.

Published: September 2016

AbstractIn 1832 Hamilton predicted that a collimated light beam propagating through a biaxial crystal parallel to one of its optical axes refracts as a slanted cone within the crystal and emerges as a hollow light cylinder, this optical effect being named as conical refraction (CR). The diffractive solution of CR presented by Belsky and Khapalyuk in 1978 and the corresponding re‐formulation carried out by Berry in 2004 rekindled this old and almost forgotten phenomenon. In this article, we review the CR phenomenon following different approaches that allow understanding light propagation in biaxial crystals, including the case of multiple crystals in cascade. We then focus on the description of the singular properties of the CR beams, presenting some examples such as optical bottle beams and beams carrying orbital angular momentum. All these features are used to introduce some of the most appealing applications of CR in the fields of optical trapping, free‐space optical communications, polarization metrology, super‐resolution imaging, two‐photon polymerization, and lasers.

Manipulating light–matter interaction in a gold nanorod assembly by plasmonic coupling
Authors: Li Jin‐Xiang , Xu Yi , Dai Qiao‐Feng , Lan Sheng , Tie Shao‐Long 
Published: September 2016

AbstractThe interaction of light with a single gold nanorod (GNR) depends strongly on the polarization and wavelength of the light. For isolated GNRs, the maximum of the polarization (wavelength)‐dependent linear and nonlinear absorption appear at the same excitation polarization (wavelength). Here, it is demonstrated that these relationships can be manipulated in a GNR assembly composed of randomly distributed and oriented GNRs by controlling the plasmonic coupling strength between GNRs. It is revealed that the strongly localized modes resulting from the plasmonic coupling of GNRs play a crucial role in determining these relationships. For a GNR tetramer, it is shown by numerical simulation that the maximum two‐photon absorption achieved at a particular polarization can be switched to the minimum absorption and vice versa by controlling the coupling strength. More importantly, it is demonstrated both numerically and experimentally that the two‐photon‐absorption peak of a GNR assembly can be made to be different from its single‐photon‐absorption peak by increasing the coupling strength. Both properties are distinct from previous experimental observations. Our findings provide a useful guideline for engineering the interaction of light with complex plasmonic systems.

Authors: Gilmore Kevin J. , Morat Tobias , Doherty Timothy J. , Rice Charles L. 
Published: September 2016

ABSTRACTIntroduction: Loss of motor units (MUs) and alterations in MU properties are major factors in development of sarcopenia. The purpose of this study was to compare MU properties among 3 groups categorized as either pre‐sarcopenic (n = 7), sarcopenic (n = 7), or severely sarcopenic (n = 5), all with similarly aged subjects (75–82 years). Methods: Using decomposition‐enhanced quantitative electromyography, MU number estimates and neuromuscular stability measures of near‐fiber (NF) jitter and jiggle were derived in addition to contractile properties of ankle dorsiflexors. Results: MU number estimates were similar across groups; however, maximal voluntary strength in the severe sarcopenia group was 27% and 37% less than the sarcopenic and pre‐sarcopenic groups, respectively. Moreover, NF jiggle was 31% greater in the severe group compared with pre‐sarcopenia, NF jitter was 43% greater in the severe group compared with the pre‐sarcopenic group. Conclusion: Unlike MU number estimates, strength and MU stability differed across groups and related to degree of sarcopenia. Muscle Nerve 55: 676–684, 2017

ObjectiveObesity is a risk factor for breast cancer recurrence. Rural women have higher obesity rates compared with urban women and are in need of distance‐based interventions that promote long‐term weight loss.MethodsIn this two‐phase trial, rural breast cancer survivors who lost >5% of their starting weight during a 6‐month lifestyle intervention (delivered through weekly group conference calls) were randomized to one of two 12‐month interventions for weight loss maintenance: continued biweekly phone‐based group counseling or mailed newsletters. The primary outcome was weight regain from 6 to 18 months. Secondary outcomes included dichotomous measures of weight change and costs.ResultsMean weight loss at 6 months was 14.0 ± 5.1%. Participants in the group phone condition regained less weight (3.3 ± 4.8 kg) compared with participants in the newsletter condition (4.9 ± 4.8 kg; P = 0.03). At 18 months, 75.3% of participants in the group phone condition remained ≥5% below baseline weight compared with 57.8% in the newsletter condition (P = 0.02). Incremental cost‐effectiveness ratios were $882 to keep one more person ≥5% below baseline weight.ConclusionsA lifestyle intervention incorporating group phone‐based support improved the magnitude of weight loss maintained and increased the proportion of survivors who maintained clinically significant reductions.
