ABSTRACT
Objectives: To assess the oral health status and salivary composition in a group of children suffering from bronchial asthma. Materials and Methods: The sample consisted of sixty asthmatic children, sixty healthy negative controls, and sixty healthy positive controls of both sexes with age ranging from 4 to 12 years old. The asthmatics were grouped according to disease severity into mild, moderate, or severe asthmatic. All the children were clinically examined to assess their dental caries experience (decayed, indicated for extraction, and filled primary tooth [def] and decayed-missing-filled permanent tooth [DMF]), dental erosion condition (tooth wear index), and gingival health condition (gingival index [GI]). Salivary samples were collected and assessed for salivary flow rate, salivary pH, and the level of calcium, sodium, and potassium. Results: The results of this study revealed that asthmatic children presented significantly higher def, DMF score, and GI mean values compared to the control groups. Severe asthmatics significantly presented the highest def and GI score. Salivary analysis revealed reduced stimulated salivary flow rate and altered salivary pH. In addition, significantly elevated mean salivary calcium level found to be associated with higher GI mean score. Conclusions: Children suffering from bronchial asthma should receive special dental preventive attention as presented with greater risk for oral and dental diseases as compared to the healthy controls.

Abstract. We investigated the combined effect of ocean acidification and warming on the
dynamics of the phytoplankton fall bloom in the Lower St. Lawrence Estuary
(LSLE), Canada. Twelve 2600 L mesocosms were set to initially cover a wide
range of pHT (pH on the total proton scale) from 8.0 to 7.2
corresponding to a range of pCO2 from 440 to
2900 µatm, and two temperatures (in situ and +5 ∘C). The
13-day experiment captured the development and decline of a nanophytoplankton
bloom dominated by the chain-forming diatom Skeletonema costatum.
During the development phase of the bloom, increasing pCO2
influenced neither the magnitude nor the net growth rate of the
nanophytoplankton bloom, whereas increasing the temperature by 5 ∘C
stimulated the chlorophyll a (Chl a) growth rate and maximal particulate
primary production (PP) by 76 % and 63 %, respectively.
During the declining phase of the bloom, warming accelerated the loss of
diatom cells, paralleled by a gradual decrease in the abundance of
photosynthetic picoeukaryotes and a bloom of picocyanobacteria. Increasing
pCO2 and warming did not influence the abundance of
picoeukaryotes, while picocyanobacteria abundance was reduced by the increase
in pCO2 when combined with warming in the latter phase of
the experiment. Over the full duration of the experiment, the time-integrated
net primary production was not significantly affected by the
pCO2 treatments or warming. Overall, our results suggest
that warming, rather than acidification, is more likely to alter
phytoplankton autumnal bloom development in the LSLE in the decades to come.
Future studies examining a broader gradient of temperatures should be
conducted over a larger seasonal window in order to better constrain the
potential effect of warming on the development of blooms in the LSLE and its
impact on the fate of primary production.

Published: August 2018

New microstrip antenna initiated from the portions of 1st order structures of Sierpinski square geometry is modeled in this paper as quasi-fractal device using an FR4 substrate of 4.4 dielectric constant, 1.6 mm thickness and 0.02 loss tangent. The intended microstrip antenna is designed for band frequencies of 3.5 and 7.8 GHz for WiMAX and metrological satellite applications with a bandwidth of 0.66 and 0.78 GHz for each band respectively. The designed antenna has considerable compact size that is smaller than many reported fractal and non-fractal antenna structures in the literature. Also, it has interesting return loss and radiation results that can be employed in diverse wireless devices. Measured input reflection coefficient, radiation patterns and gain results have been found in good agreement with those predicted by simulations.

Beyond Phototherapy: Recent Advances in Multifunctional Fluorescent Nanoparticles for Light‐Triggered Tumor Theranostics
Authors: del Rosal Blanca , Jia Baohua , Jaque Daniel 
Published: August 2018

AbstractNanoparticles (NPs) have attracted great attention for cancer diagnosis and therapy thanks to their unique properties that enable specific tumor uptake, image‐guided diagnosis, and tumor suppression triggered by one or more therapeutic modalities. Light‐activated NPs have gained particular interest as minimally invasive theranostic agents for fluorescence‐guided tumor diagnosis and highly selective phototherapy. The most recent advances in the field focus on shifting their spectral operation range to the second biological window (1000–1400 nm), while improving their efficacy, selectivity, and multifunctionality. In the past few years, multiple systems capable of light‐triggered tumor diagnosis through fluorescence imaging (and in many cases, other imaging modalities) and subsequent tumor therapy have been synthesized and evaluated in small animal models. This review summarizes the different approaches for in vivo tumor theranostics, highlighting their advantages and limitations, and provides a critical analysis of the current state of the field.

Published: August 2018

AbstractLithium metal anodes suffer from serious safety issues and rapid capacity fade because of nonideal plating/stripping behaviors. Lithium nucleation on undesired positions usually results from nonuniform multiphysical field distributions and the dynamically changing interface thermodynamics. In this study, a sandwich composite anode consisting of gold nanoparticles pillared reduced graphene oxide (rGO) is designed . Because gold nanoparticles preferentially induce lithium nucleation, the typically uncontrolled lithium deposition process becomes a highly nucleation‐guided process. Because the sandwich structure of the Au‐pillared rGO provides a stable anode morphology with cycling and stabilizes the solid electrolyte interface layer, the Au‐pillared rGO delivers a high Coulombic efficiency of up to 98% for at least 200 cycles for 1600 h. Using this pillared structure, an interlayer plating process is revealed in rGO‐sandwiched anodes, which differ from either conventional metallic anodes or intercalation anodes. The Au‐pillared design bridges the gap between metal and intercalation anodes, and provides a novel strategy to improve the efficiencies and cyclability of lithium anodes.

Published: August 2018

AbstractThe fouling mitigation of anion exchange membrane (AEM) performance is a great challenge faced by many membrane applications (e.g., electrodialysis, ED). In this study, a novel AEM is modified with dual functional layers prepared by coating hydrophilic polydopamine (PDA) on quaternized poly(2,6‐dimethyl‐1,4‐phenylene oxide), and subsequently grafting with zwitterionic structure of sulfobetaine methacrylate via the aza‐Michael reaction, aiming to improve the membrane fouling resistant. In particular, the sodium dodecyl benzene sulfonate (SDBS) is used as model foulant. The hydrophilic layer (PDA) and hydrophilic/negatively charged zwitterionic surface of AEM, act as useful barriers via physical blocking and electrostatic repulsion, respectively. The proposed modification can restrict the deposition and/or chemical adsorption of SDBS. The time elapsed until the occurrence of fouling (transition time) is significantly enhanced as result of modification (around five times longer) as evidence of the reinforced antifouling property. The enhanced performance of modified membrane is also confirmed by desalting experiments in terms of NaCl rejection potential. The facile preparation and advanced performances of dual functional layers modified AEM suggest its potential ED application.

Published: August 2018

AbstractSecurity monitoring and precaution for private information and property plays a key role in the smart home system. In this work, a triboelectric nanogenerator‐based active sliding sensor is demonstrated which can monitor the position, displacement, velocity, and direction of a contact sliding objects. The device consists of a mover and a stator which operate in sliding mode. Two aligned column arrays of copper electrodes are coated on the substrate as the mover, while two interdigitated copper electrode pairs with relative position shift are coated under a polytetrafluoroethylene film as the stator. The experimental results show that a single device can generate a voltage of about 5 V at a resistance load of 60 MΩ at a sliding velocity of 0.5 m s–1. The sliding sensor can detect an ultralow velocity in 0.001 m s–1 as well as the sliding direction of the mover. The sensor can be fixed on the drawer and door to detect the motion parameters which are sent to a remote client application for security monitoring in smart home systems. The proposed sliding sensor has great potential in the Internet of things, personal motion feature recognition, and meandering trajectory tracking.

Published: August 2018

AbstractA transparent conductive film incorporating silver nanowires (AgNW TCF) is fabricated through roll‐to‐roll (R2R) slot‐die coating and a subsequent calendering process and applied to a resistive touch panel. To produce a uniform AgNW film on a flexible polyethylene terephthalate substrate, the R2R slot‐die coating is optimized in terms of the solvent, concentration, and flow rate of the AgNW solution, and the length of the AgNWs synthesized using a polyol method. The coated AgNW TCF is calendered between two rolls to produce percolation paths in the film. During the calendering, the roll temperature, applied pressure, and web speed are optimized to yield a low sheet resistance of 28 Ω sq−1 with a transmittance of 86% at 550 nm. To demonstrate the functionality of the AgNW TCF, a coating of SiO2 microspheres is also applied to form a spacer layer, again using R2R slot‐die coating. A resistive touch panel is thus successfully implemented. The effect of the calendering process is confirmed by observing the operation of the touch panel, which is found to be more sensitive and accurate. The integrated manufacturing process for producing an AgNW TCF, presented herein, can be applied to many other major fields.
Nanoporous Organic Field‐Effect Transistors Employing a Calixarene Dielectric for Sub‐ppb Gas Sensing

Published: August 2018

AbstractThe increase of exposure to volatile organic compounds in general, and endocrine disruptors in particular, through daily healthcare consumer goods urgently calls for the development and commercialization of cheap and easy‐to‐use sensors to detect these molecules in air. Organic semiconductors (OSCs) promise the mass fabrication of cheap and flexible sensors, under the condition that the fabrication of functional thin films having the right morphology can be fully harnessed. Nanoporous morphologies are interesting in the field of gas sensing because they facilitate the diffusion of gas molecules to the active volume of organic field‐effect transistors (OFETs), at the vicinity of the gate dielectric. Nanoporous films of OSCs are, however, challenging to produce and to transfer into working sensors. Usage of nanoporous OSC films deposited on a sensitive 4‐tert‐butylcalix[6]arene gate dielectric as the active layer of an OFET‐based gas sensor is proposed here. The semiconducting molecules are self‐assembled into nanoporous films at the interface between air and water, allowing their transfer to practically any gas‐sensitive dielectric substrate. The OFET built on this film stack is used here to sense the presence of methyl 4‐hydroxybenzoate (methylparaben) in air at concentrations below 1 ppb.

Published: August 2018

AbstractTuberous sclerosis complex (TSC) is associated with a wide range of behavioral, psychiatric, intellectual, academic, neuropsychological, and psychosocial difficulties, which are often underdiagnosed and undertreated. Here, we present a clinical update on TSC‐associated neuropsychiatric disorders, abbreviated as “TAND,” to guide screening, diagnosis, and treatment in practice. The review is aimed at clinical geneticists, genetic counselors, pediatricians, and all generalists involved in the assessment and treatment of children, adolescents and adults with TSC, and related disorders. The review starts with a summary of the construct and levels of TAND, before presenting up‐to‐date information about each level of investigation. The review concludes with a synopsis of current and future TAND research.
Effects of sulfur additive on the transformation behaviors of γ‐Fe2O3 and coal liquefaction performances under mild conditions

Published: August 2018

AbstractIn this paper, the effects of sulfur on liquefaction performances of coal and the transformation behaviors of γ‐Fe2O3 at the S/Fe atomic ratio of 0–1.3 under mild conditions were investigated. Compared with traditional liquefaction processes, the oil yield and coal conversion were insensitive to the addition of sulfur under mild conditions (temperature of 430°C, reaction pressure of 8.5–13.8 MPa). The optimum S/Fe atomic ratios at the initial H2 pressures of 4.0 and 8.0 MPa were 0.6 and 1.0, which were lower than those of traditional liquefaction processes. As the S/Fe atomic ratio increased from 0 to 0.6 (at the initial H2 pressure of 4.0 MPa), the oil yield and coal conversion increased by 4.0% and 3.8%, and this could be attributed to the synergistic effects between the relatively sulfur‐rich structure of pyrrhotite (Fe0.8917S) and the relatively high partial pressure of H2S. In addition, over 85% of sulfur was retained in the solid products, and the effect of S/Fe atomic ratio on the sulfur distribution was tiny. However, increasing H2 pressure was conducive to the transfer of sulfur to the gaseous products.
Adaptive Composite Fuzzy Dynamic Surface Control for Electro‐Hydraulic‐System, with Variable‐Supply‐Pressure
Authors: Guo Qinyang , Shi Guanglin , Wang Dongmei 
Published: August 2018

AbstractThis paper presents a novel adaptive composite fuzzy dynamic surface controller for a variable‐supply‐pressure electro‐hydraulic‐system in the presence of unknown nonlinear friction effects. To avoid analytic calculation, command filters are utilized to produce certain virtual controllers and their derivatives. A fuzzy logic system is designed to approximate and compensate the unknown nonlinear friction influences of the electro‐hydraulic‐system. To achieve a precise approximation, the prediction error of a designed serial‐parallel estimation model and the compensated tracking error are both used to develop the composite adaptive law. Comparative simulation and experimental results are obtained to verify the effectiveness of the proposed control method.
Mean‐variance hedging with basis risk
Authors: Xue Xiaole , Zhang Jingong , Weng Chengguo 
Published: August 2018

AbstractBasis risk arises in a number of financial and insurance risk management problems when the hedging assets do not perfectly match the underlying asset in a hedging program. Notable examples in insurance include the hedging for longevity risks, weather index–based insurance products, variable annuities, etc. In the presence of basis risk, a perfect hedging is impossible, and in this paper, we adopt a mean‐variance criterion to strike a balance between the expected hedging error and its variability. Under a time‐dependent diffusion model setup, explicit optimal solutions are derived for the hedging target being either a European option or a forward contract. The solutions are obtained by a delicate application of the linear quadratic control theory, the method of backward stochastic differential equation, and Malliavin calculus. A numerical example is presented to illustrate our theoretical results and their interesting implications.
Self–other differences in multiattribute decision making: Compensatory versus noncompensatory decision strategies
Authors: Von Gunten Curtis D. , Scherer Laura D. 
Published: August 2018

AbstractWhen making decisions where options involve multiple attributes, a person can choose to use a compensatory, utility maximizing strategy, which involves consideration and integration of all available attributes. Alternatively, a person can choose a noncompensatory strategy that extracts only the most important and reliable attributes. The present research examined whether other‐oriented decisions would involve greater reliance on a noncompensatory, lexicographic decision strategy than self‐oriented decisions. In three studies (Mturk workers and college students), the difference in other‐oriented versus self‐oriented decisions in a medical decision context was explained by a subsample of participants that chose the death minimizing operation on all 10 decisions (Study 1) and a subsample of participants who self‐reported that they used a strategy that minimized the chance of death on every decision (i.e., a lexicographic mortality heuristic; Study 2). In Study 2, tests of mediation found that self‐reported use of the mortality heuristic completely accounted for the self–other effect on decisions. In Study 3, participants were more likely to report prospectively that they would adopt the mortality heuristic when making decisions for others than for themselves, suggesting that participants were not mistakenly inferring a lexicographic decision strategy from their past behavior. The results suggest that self–other effects in multiattribute choice involve differential use of compensatory versus noncompensatory decision strategies and that beyond this group difference, individual differences in the use of these strategies also exist within self‐oriented and other‐oriented decisions.

Aqueous Phase Synthesis of Hydrocarbons from Reactions of Guaiacol and Low Molecular Weight Oxygenates
Authors: Agblevor Foster A. , Jahromi Hossein 
Published: August 2018

AbstractCatalytic pyrolysis of lignocellulosic biomass generates water‐soluble low molecular weight oxygenates such as acetic acid, acetone, furfural, butanone, guaiacol, phenol and others in significant quantities that will affect the profitability of the biorefinery process. A new heterogeneous catalyst has been developed that catalyzes the reaction of carbonyl compounds with unsaturated ethers in aqueous medium to produce C6 to C15 hydrocarbons in a one‐pot synthesis. These reactions are called “carbonyl alkylations” because the carbonyl carbon chain was added to the aromatic ring and the oxygen was eliminated without loss of carbon. The C1 to C4 ketones and aldehydes produce alkylated benzenes while the C5 and higher carbonyl compounds alkylated the benzene ring and also opened the benzene ring to produce long chain internal alkene compounds. All the reactions occurred in the aqueous media at 300–350 °C on a supported nickel catalyst. The gaseous products included low molecular weight hydrocarbons such as methane, propane, butane, and pentane. Thus, it has been demonstrated for the first time that it is possible to produce a wide array of hydrocarbons from low molecular weight biomass derived oxygenates.

AbstractLithium metal has shown great promise as an anode material for high‐energy rechargeable batteries. However, interfacial instability caused by an unstable solid‐electrolyte interphase (SEI) and dendrite growth has impeded the realization of Li anodes for practical applications. Recently, we reported a potentiostatic stripping−galvanostatic plating electrochemical polishing method to simultaneously create atomically flat Li and a molecularly smooth SEI, leading to a near‐perfect Li anodes that exhibit much enhanced electrochemical performance. In this paper, key factors including anodic stripping potentials, cathodic plating current densities, and types of salt and solvent systems are further investigated in detail based on the understanding of electrode reactions taking place during polishing. In particular, the importance of considerations on the mutual constrains between electropolishing and SEI formation and, thus, the necessity of fine control of potential and/or current is elucidated, which serves as a general rule for the successful application of electrochemical polishing of Li as well as other metals that involve the formation of SEIs.
