Authors: Lin Bingjing , Tieu A. Kiet , Zhu Hongtao , Kosasih Buyung , Novareza Oyong 
Published: May 2017

AbstractThe adsorption structure of aqueous triblock copolymer polypropylene oxide‐polyethylene oxide‐polypropylene oxide, PPO‐PEO‐PPO, on the Si surface was studied using neutron reflectometer. It is found that PEO blocks formed the outer layer of the adsorbed PPO‐PEO‐PPO film, while PPO blocks formed the inner layer and served as the anchor blocks. The adhesion strength of adsorbed PPO‐PEO‐PPO copolymer film was evaluated using atomic force microscopy and scratch tests. The results revealed that the molecular structure of triblock copolymer had a considerable effect on the adhesion strength. The triblock copolymer with a longer PPO chain and a higher weight percentage of PPO exhibited stronger adhesion and better lubrication performance.

Published: May 2017

ObjectiveThe purpose of this study is to assemble a laser system for the selective removal of dental composite from tooth surfaces, that is feasible for clinical use incorporating a spectral feedback system, a scanning system, articulating arm and a clinical hand‐piece, and evaluate the performance of that system on extracted teeth.MethodsTen extracted teeth were collected and small fillings were placed on the occlusal surface of each tooth. A clinical system featuring a CO2 laser operating at 50 Hz and spectral optical feedback was used to remove the composite. Removal was confirmed using a cross polarized optical coherence tomography (CP‐OCT) system designed for clinical use.ResultsThe system was capable of rapidly removing composite from small preparations on tooth occlusal surfaces with a mean loss of enamel of less than 20 μm.ConclusionWe have demonstrated that spectral feedback can be successfully employed in an automated system for composite removal by incorporating dual photodiodes and a galvanometer controlled CO2 laser. Additionally, the use of registered OCT images presents as a viable method for volumetric benchmarking. Overall, this study represents the first implementation of spectral feedback into a clinical hand‐piece and serves as a benchmark for a future clinical study. Lasers Surg.

Forecasts of extreme precipitation in the western Balkans in May 2014: model skill and sensitivity to the vertical co‐ordinate
Authors: Marjanović Dragana , Veljovic Katarina , Zaric Miroljub 
Published: May 2017

ABSTRACTThis study examines the simulation of the catastrophic precipitating event that occurred on 14–16 May 2014 over the western Balkans, using two regional models, the Eta model and the Weather Research and Forecasting Non‐hydrostatic Mesoscale Model (WRF‐NMM). This case was an extreme precipitation event with very large precipitation totals exceeding 200 mm in 72 h. The Eta model was run in two variants, switched to use the eta co‐ordinate with sloping steps and switched to use the sigma co‐ordinate. The aim of this study was to analyse the ability of the regional model to forecast heavy precipitation successfully as well as the impact of the vertical co‐ordinate on the forecasting of extreme precipitation events based on realistic model simulation. Experiments show the ability of regional models to reproduce extreme accumulations for 2 days of heavy precipitation with bias adjusted equitable threat score ranging from 0.3 to 0.5 for precipitation greater than the analysed threshold values (25–55 mm day−1), whereby the Eta model exhibits a slight advantage over the WRF‐NMM and the run of the Eta model switched to the eta co‐ordinate has the smallest frequency bias. For larger observed accumulations exceeding 50 mm day−1 all forecasts tend to be more biased. The root mean square precipitation difference varies insignificantly between the three forecasts. The results of the experiment indicate that, in the case of the extreme precipitation considered in this study, scores of the forecasts of the Eta model for 10 m wind speed and 2 m temperature show a small dependence on the vertical co‐ordinate and in favour of the run with the eta co‐ordinate.

Published: May 2017

AbstractBackgroundOver 175,000 Americans underwent bariatric surgery in 2013 alone, resulting in rapid growth of the massive weight loss population. As obesity is a known risk factor for breast cancer, plastic surgeons are increasingly challenged to reconstruct the breasts of massive weight loss patients after oncologic resection. The goal of this study is to assess the outcomes of autologous breast reconstruction in postbariatric surgery patients at a single institution.MethodsPatients who underwent autologous breast reconstruction between 2008 and 2014 were identified. Those with a history of bariatric surgery were compared to those without a history of bariatric surgery. Analysis included age, ethnicity, BMI, comorbidities, flap type, operative complications, and reoperation rates. Propensity matched analysis was also conducted to control for preoperative differences between the two cohorts.ResultsFourteen women underwent breast reconstruction following bariatric surgery, compared to 1,012 controls. Outcomes analysis revealed significant differences in breast revisions (1.35 vs. 0.61, P = .0055), implant placements (0.42 vs. 0.08, P = .0003), and total OR visits (2.78 vs. 1.67, P = .0007). There was no significant difference noted in delayed healing of the breast (57.4% vs. 33.7%, P = .087) or donor site (14.3% vs. 15.8%, P = 1.00).ConclusionsAs the rise in bariatric surgery mirrors that of obesity, an increasing amount of massive weight loss patients undergo treatment for breast cancer. We demonstrate profound differences in this patient population, particularly in regards to revision rates, which affects operative planning, patient counseling, and satisfaction.
Investigation of sub‐micron size cenosphere fillers and filler loading on the mechanical and tribological peculiarity of polyester composites
Authors: Singh Akant Kumar , Siddhartha  , Yadav Sanjay 
Published: May 2017

This paper investigates the effect of sub‐micron size cenosphere filler and filler loading on mechanical and dry sliding wear property of polyester composites. Composites are fabricated by filling with 10 and 20 wt% of 800 and 200‐nm size of cenosphere filler particles. Neat polyester composite is also prepared for comparison analysis. Dry sliding wear test is conducted for these composites over a range of sliding distance with different sliding velocities and applied loads on a pin‐on‐disc wear test machine. Taguchi methodology and analysis of variance (ANOVA) is used to analyze the friction and wear characteristics of the composites. The artificial neural network (ANN) approach is implemented to the friction and wear data for corroboration. In this work, mechanical properties of composites such as hardness, tensile strength, tensile modulus, flexural strength, and compressive strength revealed that mechanical properties and wear resistance of the composites increase with a decrease in the particle size. The measured Young's moduli are comparable to standard theoretical prediction models. The morphology of worn composite specimens has been examined by scanning electron microscopy to understand the dominant wear mechanisms. Finally, optimal factor settings are determined using a genetic algorithm (GA). Copyright © 2017 John Wiley & Sons, Ltd.

Published: May 2017

AbstractFor a viable and commercial attractive integration of vehicle integrated photovoltaic applications (ViPVs) energy forecasting is required as a foundation for business case calculation. The developed algorithm facilitates the forecast of annual power distribution and solar energy yield along any given track tested on a German use case. A high temporal and spatial resolution of the meteorological database providing ambient temperature, wind speed, and global horizontal irradiance was determined as a necessity to preserve the irradiance distribution and consequently the power distribution available throughout the year. For ViPV module temperature, respectively, module efficiency benefits strongly from head wind. As a consequence, the performance of ViPV under motion was identified as superior to non‐mobile PV installations. The potential annual energy yield of the three showcasing commercial semi‐trailer lorries operating in Germany is identified to be 3–7 MWh depending on the used cell technology. The potential energy gain due to head wind cooling is estimated to be 20–75 kWh per trailer and year. Copyright © 2017 John Wiley & Sons, Ltd.

Published: May 2017

We report here a rapid and sensitive technique for negative visualization of protein in 1D and 2D SDS‐PAGE by using 2′, 7′‐dichlorofluorescein (DCF), which appeared as transparent and colorless bands in an opaque gel matrix background. For DCF stain, down to 0.1–0.2 ng protein could be easily visualized within 7 min by only two steps, and the staining is fourfold more sensitive than that of Eosin Y (EY) negative stain and glutaraldehyde (GA) silver stain, and eightfold more sensitive than that of the commonly used imidazole‐zinc (IZ) negative stain. Furthermore, DCF stain provided good reproducibility, linearity, and MS compatibility compared with those of IZ stain. In addition, the potential staining mechanism was investigated by colorimetric experiment and molecular docking, and the results demonstrated that the interaction between DCF and protein occurs mainly via van der waals force, electrostatic interaction, and hydrogen bonding.

ABSTRACTMicrostructured surfaces have great potentials to improve the performances and efficiency of optoelectronic devices. In this work, a simple robust approach based on surface instabilities was presented to fabricate poly(3‐hexylthiophene‐2,5‐diyl) (P3HT) films with ridge‐like/wrinkled composite microstructures. Namely, the hierarchically patterned films were prepared by spin coating the P3HT/tetrahydrofuran (THF) solution on a polydimethylsiloxane (PDMS) substrate to form stable ridge‐like structures, followed by solvent vapor swelling to create surface wrinkles with the orientation guided by the ridge‐like structures. During spin coating of the P3HT/THF solution, the ridge‐like structures were generated by the in‐situ template of the THF swelling‐induced creasing structures on the PDMS substrate. To our knowledge, it is the first report that the creasing structures are used as a recoverable template for patterning films. The crease‐templated ridge‐like structures were well modulated by the THF swelling time, the modulus of the PDMS substrate, the P3HT/THF solution concentration and the selective/blanket exposure of the PDMS substrate to O2 plasma. UV–vis and fluorescence spectrometry measurements indicated that the light absorption and fluorescent emission were improved on the hierarchically patterned P3HT films, which can be utilized to enhance the efficiencies of organic solar cells. Furthermore, this simple versatile method based on the solvent swelling‐induced crease as the in‐situ recoverable template has been extended to pattern other spin‐coated films with different compositions. © 2017 Wiley Periodicals, Inc.

Trapped intermediate state of plant pyruvate phosphate dikinase indicates substeps in catalytic swiveling domain mechanism
Authors: Minges Alexander , Höppner Astrid , Groth Georg 
Published: May 2017

AbstractPyruvate phosphate dikinase (PPDK) is an essential enzyme of both the C4 photosynthetic pathway and cellular energy metabolism of some bacteria and unicellular protists. In C4 plants, it catalyzes the ATP‐ and Pi‐dependent formation of phosphoenolpyruvate (PEP) while in bacteria and protozoa the ATP‐forming direction is used. PPDK is composed out of three distinct domains and exhibits one of the largest single domain movements known today during its catalytic cycle. However, little information about potential intermediate steps of this movement was available. A recent study resolved a discrete intermediate step of PPDK's swiveling movement, shedding light on the details of this intriguing mechanism. Here we present an additional structural intermediate that possibly represents another crucial step in the catalytic cycle of PPDK, providing means to get a more detailed understanding of PPDK's mode of function.

Published: May 2017

AbstractBACKGROUNDInvestigating the impact of pesticides on non‐target organisms is essential for sustainable integrated pest management programs. We therefore assessed the toxicity of ten insecticides to the brassica caterpillar Ascia monuste and its ant predator Solenopsis saevissima and examined the effect that the insecticide synergists had on toxicity to the predator. We also assessed the residual period of control and impact of the insecticides during the brassica growing cycle.RESULTSAll insecticides except flubendiamide exhibited mortality above the threshold required by Brazilian legislation (80%). Chlorantraniliprole, cyantraniliprole, indoxacarb and spinosad exhibited lower toxicity to the ant predator than they did to the brassica caterpillar. The results obtained for synergized insecticides suggest that selectivity to the predator was due the involvement of cytochrome P450‐dependent monooxygenases. Chlorfenapyr and cyantraniliprole exhibited the highest residual periods of control to the brassica caterpillar, whereas malathion had the greatest impact on the predator.CONCLUSIONMost of the insecticides efficiently controlled the brassica caterpillar, but not all exhibited selectivity to the predator. Therefore, due to the distinctive responses of organisms with respect to residual periods of control and the impact of the insecticides, spraying frequency must be strongly considered in integrated pest management programs. © 2017 Society of Chemical Industry

Published: May 2017

Neuropilin‐1 (NRP‐1) has been found to be overexpressed in several kinds of malignant tumors, and it is postulated that in pathological angiogenesis, its interaction with the vascular endothelial growth factor 165 (VEGF165) leads to progression of tumor vascularization and growth. Herein, we present synthesis and in vitro evaluation of tetrapeptides with the general sequence KxxR, where xx represents two canonical amino acid residues or a single amino acid possessing hydrocarbon backbone. All synthesized compounds were found to be inhibitors of VEGF165/NRP‐1 interactions. The rationale behind their design was to elucidate the relationship between the xx flexibility and their inhibitory activity. Detailed molecular dynamics simulations for all synthesized compounds have been performed. A clear and quantitative relationship was found in the peptide analogues: the more flexible is the xx, the less active the analogue is. But surprisingly, highly flexible peptidomimetics with non‐natural amino acids (NH2‐(CH2)n‐COOH; n = 4,5) residues used possessed higher inhibitory activity than it was expected. Our molecular dynamics study of inhibitor/NRP‐1 complexes provides convincing explanations of divergence in the observed inhibitory activity; thus, it might give indication for design of the next generation NRP‐1 inhibitors.

Published: May 2017

AbstractCoupling of plasmonic metal nanostructures on two‐dimensional materials represents one promising approach to improve their optoelectronic device performance. In this article, we systematically investigated the interfacial interactions between Au nanoclusters and monolayer molybdenum disulfide (MoS2) and the effect of Au decoration on the electrical transport and optical properties of MoS2, through the combination of in situ MoS2 field‐effect transistor device evaluation and in situ ultraviolet photoelectron spectroscopy and X‐ray photoelectron spectroscopy measurements. The in situ X‐ray photoelectron spectroscopy/ultraviolet photoelectron spectroscopy experiments revealed a weak interfacial coupling between Au nanoclusters and monolayer MoS2. The absence of strong charge transfer between Au nanoclusters and MoS2 was further confirmed by the photoluminescence and Raman measurements. It was also found that the electron charge‐carrier concentration in monolayer MoS2 weakly depended on the coverage of Au nanoclusters. Copyright © 2017 John Wiley & Sons, Ltd.
Tightness–looseness: Implications for consumer and branding research
Authors: Torelli Carlos J. , Rodas María A. 
Published: May 2017

AbstractThis commentary highlights the importance of the tightness–looseness distinction to provide a more nuanced understanding of cross‐cultural consumer behavior (Li, Gordon & Gelfand, this issue). We provide guidelines to integrate the tightness–looseness distinction into existing cross‐cultural models of consumer behavior, and suggest how doing so can help to refine predictions about the persuasiveness of message appeals. We also discuss how the tightness–looseness distinction can enrich branding research, by suggesting future research opportunities in the domains of brand extension research and brand protection.

“European Integration Through Law”
Authors: Voßkuhle Andreas 
Published: May 2017

AbstractThis article discusses the Federal Constitutional Court’s contribution to European “integration through law” over the past decades. The Basic Law’s openness to integration and to European Law is examined, as well as the co-operation between the Federal Constitutional Court and the European Court of Justice in the execution of European Union law and the protection of fundamental rights. The author provides a number of examples to show how the instruments of identity review andultra viresreview developed by the Federal Constitutional Court secure the agenda of European integration as agreed upon in the European Treaties. He also shows how national governmental bodies are bound by the concept of responsibility with respect to the European integration process and how the Court ensures the necessary democratic legitimisation for the acts of European institutions by requiring the involvement of the German parliament in political decision-making processes related to the European Union. Finally, the author explores the idea of the legal community and the criticisms that have been levied against this concept. He concludes by positing that the European Union can only preserve itself by remaining a legal community, and that the rule of law in EU law is indispensable, particularly in times of crisis.
Dating of ultramafic rocks from the Western Alps ophiolites discloses Late Cretaceous subduction ages in the Zermatt-Saas Zone

Published: May 2017

AbstractThe Zermatt-Saas Zone was part of the Middle to Late Jurassic Tethyan lithosphere that underwent oceanic metamorphism during Mesozoic time and subduction during Eocene time (HP to UHP metamorphism). In upper Valtournanche, serpentinite, metarodingite and eclogite record a dominant S2 foliation that developed under 2.5±0.3 GPa and 600±20°C during Alpine subduction. Serpentinites contain clinopyroxene and rare zircon porphyroclasts. Clinopyroxene porphyroclasts show fringes within S2 with similar compositions to that of grains defining S2. Zircon cores show zoning typical of magmatic growth and thin fringes parallel to the S2 foliation. These features indicate crystallization of clinopyroxene and zircon fringes during HP syn-D2 metamorphism, related to the Alpine subduction. The U–Pb zircon dates for cores and fringes reveal crystallization at 165±3.2 Ma and 65.5±5.6 Ma, respectively. The Middle Jurassic dates are in agreement with the known ages for the oceanic accretion of the Tethyan lithosphere. The Late Cretaceaous - Paleocene dates suggest that the Zermatt-Saas Zone experienced high-pressure to ultra-high-pressure (HP–UHP) metamorphism at c. 16 Ma earlier than previously reported. This result is in agreement with the evidence that in the Western Alps the continental Sesia-Lanzo Zone reached the subduction climax at least from 70 Ma and was exhumed during ongoing oceanic subduction. Our results are further evidence that the Zermatt-Saas ophiolites diachronically recorded heterogeneous HP–UHP metamorphism.
