Published: October 2018

AbstractPiezoelectric nanogenerators (PENGs) have manifested their ability over the last decade to deliver sustainable electric power to nano and micro‐electromechanical systems or to make a wireless system network self‐powered by harvesting ambient tiny mechanical energy. Most of the advanced PENGs are based on 1D zinc oxide (ZnO) nanostructures (e.g., nanowires and nanorods) due to their high electromechanical coupling behavior. However, 2D ZnO nanosheets due to their buckling behavior and formation of a self‐formed anionic nanoclay layer contribute to generate direct current type piezoelectric output. Herein, a PENG based on the integration of 1D and 2D ZnO nanostructures on the same substrate is demonstrated for the first time, which is synthesized using a simple, low‐temperature, and low‐cost hydrothermal method. This device has potential to be integrated into the aircraft structural health monitoring (SHM) system to provide required small amount of electrical power to the array of sensors within the system, hence making the SHM system fully wireless.

AbstractOxide/metal/oxide transparent conductors (TCs) have attracted increasing interest in response to demands of explosively developing flexible optoelectronic devices. Fabricating continuous ultrathin metal films on supporting oxides is an unsolved conundrum due to Volmer–Weber growth. Instead of introducing a nucleation inducer, which generally results in inferior optical‐electrical performances, an oxygen plasma treatment‐assisted method is used to prepare Al‐doped ZnO/Ag/Al‐doped ZnO (AZO/Ag/AZO) TCs. Experimental results evidence that increasing surface energy and adhesion of the supporting AZO film allows the formation of a continuous Ag film as thin as 6 nm. The oxygen plasma treatment successfully suppresses the Volmer–Weber and improves the visible transmission, infrared reflectance, and conductivity of the AZO/Ag/AZO TCs. Furthermore, thicknesses of the AZO films in AZO/Ag/AZO TCs are elaborately optimized by using finite‐difference time‐domain method to balance the transmittance and reflectance. The resulting AZO/Ag/AZO TCs are incorporated in low‐emissivity heaters that exhibit high visible transmittance (93.6%@550 nm), high infrared reflectance (67%@1500 nm), low sheet resistance (5.6 Ω □−1), and low operating voltage (5 V). These results offer valuable insight into the role of oxygen plasma treatment in altering the metal growth mode on oxide surfaces, these structural optimization methods can be extended to the development of oxide/metal/oxide‐based electronics.

Published: October 2018

AbstractBy introducing stretchability and/or deformability to planar electronics, devices can conformably attach to 3D curved surfaces with minimal invasiveness, which is of great interest for next‐generation wearables in clinical and biological applications. Here, a feasible route is demonstrated to generate deformable 3D structures as a robust platform to construct electronic systems by utilizing silver nanowires/parylene hybrid films in a way analogous to the art of kirigami. The hybrid films exhibit outstanding electrical conductivity along with decent optical transparency, flexibility, and long‐term stability. These merits enable these films to work as electrodes for electrocardiogram recording with comparable accuracy to a commercial counterpart, and to fabricate a 7‐GHz monopole antenna with good omni‐directionality and a peak gain of 1.35 dBi. More importantly, a general scheme for constructing 3D deformable electronic systems is presented, including unique patterning procedures and rational cut designs inspired by kirigami. As an example, deformable transparent humidity sensors are fabricated to work on elbows and finger joints for sweating monitoring. The strategy demonstrated here for 3D deformable system construction is versatile and holds great promise for future advanced health monitoring at diverse and complex epidermal surfaces.

Published: October 2018

AbstractThe growing cognizance of environmental matters elucidates the increasing attention thought the evaluation of bio‐based by‐products and waste materials in various applications. The agricultural‐based industry results in considerable amounts of residues containing silica. In the past decade, extensive research studies had been executed to evaluate agricultural waste materials such as rice husk and rice straw. The results of the studies point out the possibility of evaluating such wastes to produce silica‐based materials. Wheat husk is such an abundantly available waste obtained from the wheat milling process. It is containing noncrystalline silica, and thus, it can also be evaluated to produce value added materials. This study presents a comprehensive overview of the researches carried out on the properties and utilization of wheat husk as a silica source. The summary and discussion presented in this review would provide knowledge on wheat husk that is convenient to be utilized for the low‐cost and sustainable production of silica‐based materials such as aerogel, metal silicates, zeolite, silica‐based ceramics, and composites.

Premise of the StudyExpressed sequence tag–simple sequence repeat (EST‐SSR) markers were isolated for Vriesea carinata, an endemic bromeliad from the Brazilian Atlantic Forest. These SSR loci may be used to investigate the genetic diversity and population structure of this species and related bromeliads.Methods and ResultsBased on the transcriptome data of V. carinata, 30 primer pairs were designed and selected for initial validation. Of these primer pairs, 16 generated suitable SSR loci in 69 individuals. The number of alleles per locus ranged from one to 13; the levels of observed and expected heterozygosity per locus ranged from 0.000 to 1.000 and from 0.000 to 0.935, respectively. All loci produced heterologous amplification. Transferability of the loci was tested in 15 species belonging to three Bromeliaceae subfamilies.ConclusionsThe developed EST‐SSR markers revealed polymorphism in the four studied populations and could be useful to investigate the genetic diversity of V. carinata and related species. The markers may also be suitable for novel gene annotation and discovery.

Published: October 2018

AbstractThis paper considers robust consensus problem for Lur'e networks with incrementally nonlinearity and unknown disturbance, under a given directed communication topology. Both incrementally sector bounded nonlinearities and incrementally passive nonlinearities are investigated. A distributed protocol is proposed to achieve global consensus. In the design of consensus protocol, H∞ technique is used to attenuate the effect of disturbance. Moreover, the design conditions for robust H∞ consensus are formulated into linear matrix inequalities. Finally, numerical simulations are used to demonstrate the effectiveness and superiority of the proposed method.

Published: October 2018

ObjectivesThe anticonvulsant valproic acid (VPA) has a known teratogenic effect capable of inducing major congenital malformations and developmental disorders. A comparative teratogenicity study of VPA and its analog valnoctamide (VCD), which is a new generation candidate antiepileptic drug, was carried out using Swiss Vancouver (SWV) mice.MethodsPregnant SWV dams were treated with either a single intraperitoneal injection of VPA (1.8 and 2.7 mmol/kg), VCD (1.8 and 2.7 mmol/kg), or vehicle on E8:12 (gestational day:hour). The numbers of implantation and resorption, viable and dead fetuses, and the presence of gross fetal visceral and skeletal abnormalities were determined (E18). Real‐time Polymerase chain reaction (RT‐PCR) arrays were used to analyze the expression of 84 genes related to the processes of neurogenesis and neural stem cell differentiation.ResultsSignificant decreases in pregnancy weight gain and the number of live fetuses were observed when VPA was administered at the high dose, whereas the percentage of exencephalic fetuses was significantly increased in VPA treated compared with an equivalent VCD dosage group. There was a dose‐related increase in visceral defects in the VPA‐exposed fetuses. Missing skull bones and fused vertebrae in fetuses occurred at the high dose of VPA. Three genes (Mtap2, Bmp8b, and Stat3) were significantly upregulated and one (Heyl) was downregulated in samples from VPA‐treated dams.ConclusionsThe study demonstrates that the teratogenicity of VPA was significantly greater than that of an equimolar dose of VCD. Four genes (Mtap2, Bmp8b, Stat3, and Heyl) represent candidate target genes for the underlying teratogenic mechanism responsible for VPA‐induced malformations.

Published: October 2018

AbstractFür einen breiten Einsatz von Carbonbeton in der Baupraxis muss der Verbund zwischen Betonmatrix und Bewehrungselementen auch bei hohen Temperaturen sowie im Brandfall gewährleistet sein. Anorganisch imprägnierte Faserbewehrungselemente bieten eine vielversprechende Alternative zu den marktüblicheren polymerimprägnierten Carbonstrukturen, deren Verbundleistung sich mit steigender Temperatur deutlich verschlechtert. Wesentliche Herausforderung bei der Herstellung von mineralisch gebundenen Carbonfaserarmierungen ist die Auswahl einer passenden Verarbeitungstechnologie und geeigneter Rohstoffe. Die vorliegende Arbeit befasst sich mit dieser Herausforderung und konzentriert sich auf die mechanische Leistungsfähigkeit von dünnen Bewehrungsstäben aus mineralisch imprägnierten Carbonfasergarnen. Anhand von Auszugsversuchen wird gezeigt, dass die neuen Bewehrungselemente unter Temperaturbeanspruchung im Vergleich zu den polymerimprägnierten Referenzmaterialien einen deutlich besseren Verbund zum Beton aufweisen und dass der Verbund auch bis zu 500 °C hinreichend leistungsfähig bleibt.

Abstract

Background
Few studies have assessed changes in antihypertensive and lipid-lowering therapy after bariatric surgery. The aim of this study was to assess the 6-year rates of continuation, discontinuation or initiation of antihypertensive and lipid-lowering therapy after bariatric surgery compared with those in a matched control group of obese patients.

Methods
This nationwide observational population-based cohort study used data extracted from the French national health insurance database. All patients undergoing gastric bypass or sleeve gastrectomy in France in 2009 were matched with control patients. Mixed-effect logistic regression models were used to analyse factors that influenced discontinuation or initiation of treatment over a 6-year interval.

Results
In 2009, 8199 patients underwent primary gastric bypass (55·2 per cent) or sleeve gastrectomy (44·8 per cent). After 6 years, the proportion of patients receiving antihypertensive and lipid-lowering therapy had decreased more in the bariatric group than in the control group (antihypertensives: –40·7 versus –11·7 per cent respectively; lipid-lowering therapy: –53·6 versus –20·2 per cent; both P &lt; 0·001). Gastric bypass was the main predictive factor for discontinuation of therapy for hypertension (odds ratio (OR) 9·07, 95 per cent c.i. 7·72 to 10·65) and hyperlipidaemia (OR 11·91, 9·65 to 14·71). The proportion of patients not receiving treatment at baseline who were subsequently started on medication was lower after bariatric surgery than in controls for hypertension (5·6 versus 15·8 per cent respectively; P &lt; 0·001) and hyperlipidaemia (2·2 versus 9·1 per cent; P &lt; 0·001). Gastric bypass was the main protective factor for antihypertensives (OR 0·22, 0·18 to 0·26) and lipid-lowering medication (OR 0·12, 0·09 to 0·15).

Conclusion
Bariatric surgery is associated with a good discontinuation of antihypertensive and lipid-lowering therapy, with gastric bypass being more effective than sleeve gastrectomy.
Comparing Agent‐Based Delivery of DNA and PNA Forced Intercalation (FIT) Probes for Multicolor mRNA Imaging

Published: October 2018

AbstractFluorogenic oligonucleotide probes allow mRNA imaging in living cells. A key challenge is the cellular delivery of probes. Most delivery agents, such as cell‐penetrating peptides (CPPs) and pore‐forming proteins, require interactions with the membrane. Charges play an important role. To explore the influence of charge on fluorogenic properties and delivery efficiency, we compared peptide nucleic acid (PNA)‐ with DNA‐based forced intercalation (FIT) probes. Perhaps counterintuitively, fluorescence signaling by charged DNA FIT probes proved tolerant to CPP conjugation, whereas CPP–FIT PNA conjugates were affected. Live‐cell imaging was performed with a genetically engineered HEK293 cell line to allow the inducible expression of a specific mRNA target. Blob‐like features and high background were recurring nuisances of the tested CPP and lipid conjugates. By contrast, delivery by streptolysin‐O provided high enhancements of the fluorescence of the FIT probe upon target induction. Notably, DNA‐based FIT probes were brighter and more responsive than PNA‐based FIT probes. Optimized conditions enabled live‐cell multicolor imaging of three different mRNA target sequences.
Heterogeneous‐Backbone Foldamer Mimics of a Computationally Designed, Disulfide‐Rich Miniprotein

Published: October 2018

AbstractDisulfide‐rich peptides have found widespread use in the development of bioactive agents; however, low proteolytic stability and the difficulty of exerting synthetic control over chain topology present barriers to their application in some systems. Herein, we report a method that enables the creation of artificial backbone (“foldamer”) mimics of compact, disulfide‐rich tertiary folds. Systematic replacement of a subset of natural α‐residues with various artificial building blocks in the context of a computationally designed prototype sequence leads to “heterogeneous‐backbone” variants that undergo clean oxidative folding, adopt tertiary structures indistinguishable from that of the prototype, and enjoy proteolytic protection beyond that inherent to the topologically constrained scaffold. Collectively, these results demonstrate systematic backbone substitution to be a viable method to engineer the properties of disulfide‐rich sequences and expands the repertoire of protein mimicry by foldamers to an exciting new structural class.

Published: October 2018

AbstractA novel echinops‐like Ni@NiNC composite has been successfully fabricated by direct pyrolysis of a folic acid‐Ni complex. It was elucidated that the co‐existence of Ni and Ni−N active sites could promote the catalytic activity of ORR and OER simultaneously. Essentially, the unique echinops‐like structure with hierarchical porous morphology has indispensable contribution to charge transportation and exposure of active sites to O2 adsorption when assembled into a rechargeable zinc‐air battery.
Gas phase dehydration of glycerol to acrolein over NaHSO4@Zr‐MCM‐41 catalyst

Published: October 2018

ABSTRACTThe NaHSO4@Zr‐MCM‐41 catalyst modified by dodecyltrimethoxysilane (DTMS) showed excellent performance during the dehydration of glycerol to acrolein. The glycerol conversion and acrolein selectivity and yield on NaHSO4‐DTMS@Zr‐MCM‐41 (Cat‐2) are higher than that of NaHSO4@Zr‐MCM‐41 (Cat‐1). The dispersity of NaHSO4 is remarkably improved by an appropriate amount of DTMS modification on Cat‐2 because of the steric effect between DTMS and NaHSO4. Therefore, the total acidic amount of Cat‐2 is more than that of Cat‐1, but its acidic intensity is weaker than that of Cat‐1. The more total amount of acidity is beneficial to improve the glycerol conversion, and weaker acid strength leads to less carbon deposition. The amount of Brønsted acid sites is more than that of Cat‐1; however, the amount of Lewis acid sites is less, so the B/(B + L) of Cat‐2 is higher, which is beneficial and improves the acrolein selectivity. The Cat‐2 catalyst has proper hydrophobicity by grafting the silane group on the support surface, which can suppress the leaching of NaHSO4 because the water that existed in the glycerol aqueous solution and that was produced in the reaction is not easily adsorbed on the catalyst surface. The appropriate hydrophobicity is beneficial to the quick desorption of products, which can also suppress the coke formation. The stability of Cat‐2 is obviously higher than that of Cat‐1 because the coke that was deposited and the S elemental leaching on Cat‐1 are more serious than that of Cat‐2. The reaction pathway of the dehydration of glycerol was proposed, and the reaction conditions were optimized on the Cat‐2 catalyst.
Real‐time anomaly detection using parallelized intrusion detection architecture for streaming data

Published: October 2018

SummaryHigh usage levels of networking technologies has resulted in large amounts of data being generated. This in‐turn has lured several fraudsters, whose anomalous behaviors create undesired consequences to legitimate users. This paper proposes an Adaptive Parallelized Intrusion Detection (APID) architecture to handle the hugeness and data imbalance associated with streaming data. The architecture is composed of a feature selection strategy to reduce data size, an effective data segregation mechanism to handle data imbalance and a heterogeneous ensemble and a heuristic combiner mechanism to provide effective predictions. Adaptivity is incorporated by the reinforcement mechanism that retrains the model based on false predictions given by the model. The proposed APID architecture is generic; hence, it supports heterogeneous models and can also incorporate any number of machine learning models. Hence, it becomes flexible to adapt the model to data pertaining to any domain. Experiments were performed with KDD CUP 99, NSL‐KDD, and Koyoto 2006 datasets. Comparisons performed with recent works in literature indicates anomaly detection rates between 98% to 99% exhibiting the effectiveness of the proposed model.
Corporate governance and sustainable business conduct—Effects of board monitoring effectiveness and stakeholder engagement on corporate sustainability performance and disclosure choices
Authors: Manning Bart , Braam Geert , Reimsbach Daniel 
Published: October 2018

AbstractThis study posits that, in the absence of extensive mandatory regulation and auditing, differences in internal and external corporate governance (CG) mechanisms will explain variations in choices concerning corporate sustainability reporting and the interrelated and underlying corporate sustainability performance (CSP). Specifically, we explore whether board monitoring effectiveness as a major internal CG mechanism and stakeholder engagement as a key external CG mechanism are positively associated with sustainability reporting quality (SRQ), compliance with generally accepted sustainability reporting standards (SRC) and guidelines, and CSP for a sample of Dutch firms that have voluntarily disclosed sustainability reports during the years 2012–2016. In addition to these direct effects, we also investigate the potential indirect effects of the CG mechanisms on SRQ and SRC via CSP and distinguish between nonlagged and lag effects. Using structural equation modeling, our results show that, in the short term, monitoring effectiveness positively affects SRQ and SRC. Stakeholder engagement positively affects SRQ and SRC in the short term and is positively related to SRQ via CSP in the longer term, indicating that active stakeholders, over time, may drive companies toward more sustainable business conduct. Finally, the findings that CSP is positively related to SRQ but negatively related to SRC provide further support for signaling and legitimacy theory, respectively. Companies with superior CSP disclose high‐quality information on CSP to signal the firm's superior sustainability performance, whereas poor performing companies legitimize their inferior CSP by complying with more reporting standards, rather than by directly improving their underlying CSP.
The importance of corporate social responsibility for responsible consumption: Exploring moral motivations of consumers
Authors: Golob Urša , Podnar Klement , Koklič Mateja Kos , Zabkar Vesna 
Published: October 2018

AbstractThe motivations and actions of socially responsible consumers are important for the success of corporate social responsibility (CSR). The issues of responsible consumption or consumer social responsibility (CnSR) nevertheless continues to receive insufficient research attention. To remedy this shortcoming, we built on the value‐belief‐norm theory (VBN) and propose that normative factors induce consumers to enact CnSR in their buying behaviour. Using a survey of 462 consumers, we examined the relationships between values (self‐transcendent and self‐enhancement), an individual's view on the importance of CSR, awareness of negative societal consequences, ascribed responsibility for prosocial behaviour, personal norms, social norms, and CnSR. The findings indicate that CnSR can indeed be comprehensively explained with the variables included in VBN. Moreover, social norms also tend to significantly shape CnSR. The theoretical and practical implications of our results are discussed.
