Authors: Wu Nan , Zong Zhi‐Min , Fei Yi‐Wei , Ma Jun , Guo Feng 
Published: September 2017

AbstractBy simulating high‐temperature and high‐pressure operating conditions of an aviation engine using an autoclave, we studied the physicochemical properties and tribological behaviors of poly‐α‐olefin base oil samples during thermal oxidation at different temperatures. According to Fourier transform infrared spectrometric and gas chromatography/mass spectrometric analyses, at high temperatures the oil was oxidatively degraded to a large number of low‐molecular‐mass compounds, which influenced the viscosity, acidity, and antiwear property of the oil. © 2017 Curtin University and John Wiley & Sons, Ltd.

AbstractIn this article, we have analysed farmers' awareness about Minimum Support Price (MSP) and its impact on diversification of crops grown in India. We used nationally representative data collected by National Sample Survey Office, 70th round data. The data revealed that only 23.72 and 20.04 per cent of farmers in the rural agricultural households in India are aware of MSP of crops grown by them in kharif and rabi season, respectively. From the results of probit model, it is inferred that MSP needs to be backed up by effective procurement coupled with awareness creation by extension system to enable more number of farmers to take benefit of this safety net. We have also explored the relationship between farmers' awareness about MSP and decision to go for crop specialization using Heckman selection model. The study shows that farmers' knowledge of MSP had not lead to specialization.

Authors: Boeren Frank , Blanken Lennart , Bruijnen Dennis , Oomen Tom 
Published: September 2017

AbstractIterative control enables a significant control performance enhancement by learning feedforward command signals from previous tasks in a batch‐to‐batch fashion. The aim of this paper is to develop an approach to estimate the parameters of rational feedforward controllers that provide high performance and extrapolation capabilities towards varying tasks. An instrumental variable‐based algorithm is developed that leads to unbiased parameter estimates and optimal accuracy in terms of variance. Furthermore, a noncausal implementation of rational feedforward controllers is proposed, aiming to improve performance by means of pre‐actuation. Simulation and experimental results are presented to confirm that optimal accuracy is obtained with the proposed approach, and show the advantages of pre‐actuation in terms of performance.
Discrete‐Valued Model Predictive Control Using Sum‐of‐Absolute‐Values Optimization
Authors: Ikeda Takuya , Nagahara Masaaki 
Published: September 2017

AbstractIn this paper, we propose a new design method of discrete‐valued model predictive control for continuous‐time linear time‐invariant systems based on sum‐of‐absolute‐values (SOAV) optimization. The finite‐horizon discrete‐valued control design is formulated as an SOAV optimal control, which is an expansion of L1 optimal control. It is known that under the normality assumption, the SOAV optimal control exists and takes values in a fixed finite alphabet set if the initial state lies in a subset of the reachable set. In this paper, we analyze the existence and discreteness property for systems that do not necessarily satisfy the normality assumption. Then, we extend the finite‐horizon SOAV optimal control to infinite‐horizon model predictive control (MPC). We give sufficient conditions for the recursive feasibility and the stability of the MPC‐based feedback system in the presence of bounded noise. Simulation results show the effectiveness of the proposed method.

Published: September 2017

AbstractSodium‐ion capacitors have received much attention compared to lithium‐based systems, owing to the improved safety and earth abundancy. Here, we assembled an aqueous sodium‐ion capacitor by using nickel hexacyanoferrate and graphene as positive and negative electrodes, respectively, in 1 M Na2SO4 electrolyte. The fabricated capacitor can work in a wide potential window from 0 to 2 V, giving an energy density of 39.35 Wh kg−1 with better capacitance retention of about 91 %, even after 2000 cycles. Besides, the cost‐effective precursors as well as environmentally friendly and earth‐abundant electrolytes with high safety will ensure that the fabricated sodium‐ion capacitor system is suitable for next‐generation energy storage applications.
Temporal Analysis of Products Experiments at Atmospheric Pressure: The Epoxidation of Ethylene on Silver
Authors: Scharfenberg Ludwig , Horn Raimund 
Published: September 2017

AbstractA high‐speed pulse reactor setup for the study of chemical reactions which are catalyzed by a fixed bed is described. The benefits of this method compared to stationary‐state measurements are demonstrated using the example of ethylene epoxidation on elemental silver. It is shown that the intrinsic catalyst reactivity depends strongly on oxygen loading and has a pronounced maximum for a loading of about 50 %. In contrast, the selectivity is independent thereof. The relevance of the method for research in catalysis and its relation to the well‐established temporal analysis of products approach are illustrated and discussed.

Graphen – Das Elektrodenmaterial der Zukunft – Die elektrochemische Synthese von Graphenoxid und seine chemische Reduktion
Authors: Schedy A. , Quarthal D. , Oetken M. 
Published: September 2017

AbstractGraphen, die zweidimensionale Modifikation des Kohlenstoffs, besitzt besondere Eigenschaften. Dazu zählen z.B. die extrem gute elektrische Leitfähigkeit, seine große aktive Oberfläche und extreme Robustheit. Dadurch eignet sich Graphen besonders gut als Elektrodenmaterial in elektrischen Speichersystemen und könnte eine entscheidende Rolle in der Zukunft der Elektromobilität spielen. In diesem Beitrag wird neben einem elektrochemischen Syntheseweg für Graphen auch das Phänomen des „Restackings“ vorgestellt, welches hauptverantwortlich dafür ist, dass Graphen‐basierte Speichersysteme bisher noch nicht kommerziell eingesetzt werden.
Impacts of different land management histories on forest change

Published: September 2017

AbstractMany western North American forest types have experienced considerable changes in ecosystem structure, composition, and function as a result of both fire exclusion and timber harvesting. These two influences co‐occurred over a large portion of dry forests, making it difficult to know the strength of either one on its own or the potential for an interaction between the two. In this study, we used contemporary remeasurements of a systematic historical forest inventory to investigate forest change in the Sierra Nevada. The historical data opportunistically spanned a significant land management agency boundary, which protected part of the inventory area from timber harvesting. This allowed for a robust comparison of forest change between logged and unlogged areas. In addition, we assessed the effects of recent management activities aimed at forest restoration relative to the same areas historically, and to other areas without recent management. Based on analyses of 22,007 trees (historical, 9,573; contemporary, 12,434), live basal area and tree density significantly increased from 1911 to the early 2000s in both logged and unlogged areas. Both shrub cover and the proportion of live basal area occupied by pine species declined from 1911 to the early 2000s in both areas, but statistical significance was inconsistent. The most notable difference between logged and unlogged areas was in the density of large trees, which declined significantly in logged areas, but was unchanged in unlogged areas. Recent management activities had a varied impact on the forest structure and composition variables analyzed. In general, areas with no recent management activities experienced the greatest change from 1911 to the early 2000s. If approximating historical forest conditions is a land management goal the documented changes in forest structure and composition from 1911 to the early 2000s indicate that active restoration, including fire use and mechanical thinning, is needed in many areas.

Published: September 2017

AbstractBackgroundInformation on the course of neck pain (NP) and low back pain (LBP) typically relies on data collected at few time intervals during a period of up to 1 year.MethodsIn this prospective, multicentre practice‐based cohort study, patients consulting a chiropractor responded weekly for 52 weeks to text messages on their cell phones. Data from 448 patients (153 NP, 295 LBP) who had returned at least one set of answers in the first 26 weeks were used. Outcome measures were pain intensity (VAS) and functional outcome, assessed using four different questions: pain intensity, limitation in activities of daily living (ADL), number of days with pain in the previous week and number of days limited in ADL. Distinct patterns of pain were analysed with quadratic latent class growth analysis.ResultsThe final model was a 4‐class model for NP and LBP. The ‘recovering from mild baseline pain’ is most common (76.3% of NP patients/58.3% of LBP patients) followed by the ‘recovering from severe baseline pain’ class (16.3% NP/29.8% LBP). They follow similar trajectories when considered over a period of 6 months. Pain at baseline, duration of complaints, functional status, limitations in ADL and the score on psychosocial scales were the variables that most contributed to distinguish between groups.ConclusionsMost patients with NP or LBP presenting in chiropractic care show a trajectory of symptoms characterized by persistent or fluctuating pain of low or medium intensity. Only a minority either experience a rapid complete recovery or develop chronic severe pain.SignificanceNinety percentage of patients with neck pain or low back pain presenting to chiropractors have a 30% improvement within 6 weeks and then show a trajectory of symptoms characterized by persistent or fluctuating pain of low or medium intensity. Only a minority either experience a rapid complete recovery or develop chronic severe pain.
A nexus of linear and non‐linear relationships between tourism demand, renewable energy consumption, and economic growth: Theory and evidence
Authors: Isik Cem , Dogru Tarik , Turk Ercan Sirakaya 
Published: September 2017

AbstractThe purpose of this study is to examine the relationships between tourism development, renewable energy consumption, and economic growth in the United States, France, Spain, China, Italy, Turkey, and Germany using an innovative bootstrap panel Granger causality model. The results show that tourism development and economic growth are interdependent in Germany; whereas tourism development induces economic growth in China and Turkey, the reverse is true in Spain. Causal relationships between renewable energy and economic growth give credence to theories of renewable energy‐led growth in Spain and growth‐led renewable energy in China, Turkey, and Germany. Whereas the Italian and U.S. models demonstrate a bidirectional relationship, the Spanish, Italian, Turkish, and U.S. data show a causal link stemming from tourism development. Theoretical and policy implications are discussed within the realm of macroeconomics and sustainability.
The Challenge of Improving Coastal Mudflat Soil: Formation and Stability of Organo‐mineral Complexes
Authors: Bai Yanchao , Xue Weijie , Yan Yiyun , Zuo Wengang , Shan Yuhua , Feng Ke 
Published: September 2017

AbstractThe mudflats along the east coast of China can be important alternative sources for arable lands after amendment. The newly reclaimed mudflats as typical saline soils are not suitable for cultivation owing to high salinity and nutrient deficiencies. The key to amending mudflat saline soils into fertile soils is to reduce salinity in the top layer of soil. Salinity reduction is usually accomplished through rainfall and freshwater irrigation. However, lack of good soil aggregation status might attribute to salt solution rise through soil capillary. Increasing soil organic matter promoted the formation of organo‐mineral complexes and clustered soil aggregates, which is a prerequisite of hindering re‐salinization, improving fertility and facilitating the evolution of coastal mudflat soil into agricultural soil. Research on the formation of clustered soil aggregates during the evolution of mudflat soil into fertile soil should focus on the formation mechanism, influencing factors and regulatory mechanism of organo‐mineral complexes in the early stage after organic matter enters the soil. In addition, exploration of the effects of the special properties of mudflat soil, for example, high saline, high pH and low levels of clay particles, on the formation and stability of organo‐mineral complexes in soil is necessary. Research on this topic can provide scientific evidences to efficiently utilize organic resources and accelerate the evolution of mudflat soil into agricultural soil.

Authors: Huang Wei , Chen Xing , Jiang Xia , Zheng Binghui 
Published: September 2017

AbstractSediment microbial communities play an important role in lake trophic status. This study determined millions of Illumina reads (16S rRNA gene amplicons) to compare the bacterial communities in moderately eutrophic, lightly eutrophic, and moderately trophic regions using a technically consistent approach. The results indicated that the sediments from moderately eutrophic and trophic lake had the higher bacterial diversity than lightly eutrophic lake. Proteobacteria was the most abundant phylum (22.7%–86.2%) across samples from three regions. The sediments from moderately eutrophic region were enriched with Chloroflexi and Nitrospirae. Alphaproteobacteria, Gammaproteobacteria, and Bacteroidetes were enriched in the sediments from lightly eutrophic lake. The sediments from moderately trophic lake contained a high abundance of Acidobacteria and Deltaproteobacteria because of the low pH of the sediments in this lake. In moderately eutrophic region, Nitrospira held an absolute predominance, while Lysobacter and Flavobacterium were the most predominant genera in lightly eutrophic region. Temperature was the main factor influencing the bacterial community in the three lakes. The bacterial communities in the sediment samples obtained from moderately eutrophic lake were associated with nutrient concentration, whereas organic matter and total nitrogen contents mainly influenced the bacterial communities in sediments obtained from lightly eutrophic lake and moderately trophic lake, respectively.

AbstractDirect ink writing (DIW) is a new trend in the micro‐scale charging of energetic materials. In this study, a CL‐20 based composite was prepared using DIW, and its properties were characterized. Results indicated that the particles of the composite are found at the sub‐micron level, and a single layer measures at 2.4 μm. The composite has high density and low impact sensitivity, and its critical detonation size is around 1×0.4 mm. This feature will contribute to the detonation at the micro levelto a certain degree.

Published: September 2017

AbstractA study was conducted to compare the physicochemical properties of Hass avocado oil from different geographical locations (Mexico, Australia, United States and New Zealand). Regardless of geographical origins, Hass avocado pulp was characterized by high lipid content (61.27–62.66%). Among Hass avocados of different origins examined, avocado oil of New Zealand origin exhibited the lowest saponification value. The L*, a* and b* values for avocados of New Zealand origin were higher than others, translating into the oil being the lightest in color and containing more red and yellow pigments. The predominant fatty acids in the Hass avocado oil were oleic (42.59–50.97%) and palmitic (20.61–25.63%) acids, whereas the predominant triacylglycerols (TAGs) were OOO (21.41–34.69%) and POO (19.65–24.68%), where O and P denote oleic and palmitic acids, respectively. The melting curves of Hass avocado oil displayed three endothermic peaks, whereas the crystallization curves displayed two endothermic peaks. Hass avocado oil of New Zealand origin contained a significant amount of natural pigments and unsaturated compounds (unsaturated fatty acids and tri‐unsaturated TAGs) than Mexico, Australia and United States origins.

Abstract

Background
The purpose of this research is to analyze retinal venous pressure (RVP) of both eyes of patients who visited a Swiss ophthalmic practice and compare values among the following groups of patients with primary open-angle glaucoma (POAG), Flammer syndrome (FS), and metabolic syndrome (MetS).

Methods
RVP was measured in both eyes of all patients who visited a Swiss ophthalmic practice during March 2016 till November 2016, and the results were analyzed retrospectively. All measurements were performed by one physician by means of ophthalmodynamometry. Ophthalmodynamometry is done by applying an increasing pressure on the eye via a contact lens. The minimum force required to induce a venous pulsation is called ophthalmodynamometric force (ODF). The RVP is defined and calculated as the sum of ODF and intraocular pressure (IOP) [RVP = ODF + IOP].

Results
Spontaneous central retinal venous pulsation was present in the majority of the patients (192 out of 357, 53.8%). Spontaneous RVP rate was significantly negatively correlated with age (r = −0.348, p < 0.001). A significantly increased RVP was noted in FS, MetS, and POAG patients, particularly those POAG patients who also suffered from FS (p < 0.005).

Conclusions
Although most patients had a spontaneous RVP, those with FS, POAG, and MetS had increased RVP. Measuring RVP by means of ophthalmodynamometry provides predictive information about certain ocular diseases and aids in instituting adequate preventive measures.
Pharmacogenomics in the treatment of mood disorders: Strategies and Opportunities for personalized psychiatry
Authors: Amare Azmeraw T. , Schubert Klaus Oliver , Baune Bernhard T. 
Published: September 2017

AbstractPersonalized medicine (personalized psychiatry in a specific setting) is a new model towards individualized care, in which knowledge from genomics and other omic pillars (microbiome, epigenomes, proteome, and metabolome) will be combined with clinical data to guide efforts to new drug development and targeted prescription of the existing treatment options. In this review, we summarize pharmacogenomic studies in mood disorders that may lay the foundation towards personalized psychiatry. In addition, we have discussed the possible strategies to integrate data from omic pillars as a future path to personalized psychiatry. So far, the progress of uncovering single nucleotide polymorphisms (SNPs) underpinning treatment efficacy in mood disorders (e.g., SNPs associated with selective serotonin re-uptake inhibitors or lithium treatment response in patients with bipolar disorder and major depressive disorder) are encouraging, but not adequate. Genetic studies have pointed to a number of SNPs located at candidate genes that possibly influence response to; (a) antidepressantsCOMT,HTR2A,HTR1A,CNR1,SLC6A4, NPY,MAOA,IL1B,GRIK4,BDNF,GNB3,FKBP5,CYP2D6,CYP2C19, andABCB1and (b) mood stabilizers (lithium)5-HTT,TPH,DRD1,FYN,INPP1,CREB1,BDNF,GSK3β,ARNTL,TIM,DPB,NR3C1,BCR,XBP1, andCACNG2. We suggest three alternative and complementary strategies to implement knowledge gained from pharmacogenomic studies. The first strategy can be to implement diagnostic, therapeutic, or prognostic genetic testing based on candidate genes or gene products. The second alternative is an integrative analysis (systems genomics approach) to combine omics data obtained from the different pillars of omics investigation, including genomics, epigenomes, proteomics, metabolomics and microbiomes. The main goal of system genomics is an identification and understanding of biological pathways, networks, and modules underlying drug-response. The third strategy aims to the development of multivariable diagnostic or prognostic algorithms (tools) combining individual’s genomic information (polygenic score) with other predictors (e.g., omics pillars, neuroimaging, and clinical characteristics) to finally predict therapeutic outcomes. An integration of molecular science with that of traditional clinical practice is the way forward to drug discoveries and novel therapeutic approaches and to characterize psychiatric disorders leading to a better predictive, preventive, and personalized medicine (PPPM) in psychiatry. With future advances in the omics technology and methodological developments for data integration, the goal of PPPM in psychiatry is promising.
