Published: October 2019

Abstract
There has been little examination of: (1) associations of early-life nutrition and adolescent cognitive skills, (2) if they vary by gender, (3) if they differ by diverse contexts, and (4) contributions of post-infancy growth to adolescent cognitive attainment. We use Young Lives data on 7687 children from Ethiopia, India, Peru, and Vietnam to undertake ordinary least squares estimates of associations between age-1 height-for-age z-score (HAZ) and age-15 cognitive outcomes (math, reading, vocabulary), controlling for child and household factors. Age-1 HAZ is positively associated with cognitive scores in all countries. Child gender-specific estimates for these coefficients either do not differ (math, reading) or favor girls (vocabulary). Augmenting models to include growth in HAZ between ages 1 and 15 years that was not predicted by HAZ at age 1 reveals that such improvements are associated with higher cognitive scores, but that sex-specific coefficients for this predictor favor boys in India and Peru. The results suggest that nutritional indicators at age 1 have gender-neutral associations with math and reading and favor girls for vocabulary achievement at age 15, but unpredicted improvements in HAZ by adolescence are associated with higher cognitive scores for boys than for girls. This evidence enriches our understanding of relationships between children’s nutritional trajectories during childhood and adolescent cognitive development, and how these associations vary by gender in some contexts to the possible disadvantage of girls.

Abstract
In recent years, bridge health monitoring system has been widely used to deal with massive data produced with the continuous growth of monitoring time. However, how to effectively use these data to comprehensively analyze the state of a bridge and provide early warning of bridge structure changes is an important topic in bridge engineering research. This paper utilizes two algorithms to deal with the massive data, namely Kohonen neural network and long short-term memory (LSTM) neural network. The main contribution of this study is using the two algorithms for health state evaluation of bridges. The Kohonen clustering method is shown to be effective for getting classification pattern in normal operating condition and is straightforward for outliers detection. In addition, the LSTM prediction method has an excellent prediction capability which can be used to predict the future deflection values with good accuracy and mean square error. The predicted deflections agree with the true deflections, which indicate that the LSTM method can be utilized to obtain the deflection value of structure. What’s more, we can observe the changing trend of bridge structure by comparing the predicted value with its limit value under normal operation.
On the Crystallinity and Durability of ZDDP Tribofilm
Authors: Ueda Mao , Kadiric Amir , Spikes Hugh 
Published: October 2019

Abstract
The current trend for using lower-viscosity lubricants with the aim of improving fuel economy of mechanical systems means that machine components are required to operate for longer periods in thin oil film, mixed lubrication conditions, where the risk of surface damage is increased. Consequently, the performance and durability of the tribofilms formed by antiwear additives, and in particular zinc dialkyldithiophosphate (ZDDP), the main antiwear oil additive used in engine oils, has become an increasingly important issue. In this paper, it is confirmed that ZDDP tribofilms are initially relatively easily removed by rubbing but that they become more durable during prolonged rubbing. FIB-TEM analyses at different stages of tribofilm formation show that during the early stages of rubbing only the tribofilm close to the steel substrate is nanocrystalline, while the outer region is amorphous and easily removed. However, after prolonged rubbing all regions of the tribofilm become nanocrystalline and able to withstand rubbing in base oil without being removed. XPS analysis shows that after extended rubbing the outermost polyphosphate structures change from longer-chain structures such as metaphosphate and polyphosphate to shorter-chain structures including orthophosphate. This depolymerization of ZDDP tribofilm from long- to short-chain phosphate and consequent nanocrystallization are driven by heat and shear stress. EDX analysis shows that this conversion is promoted by diffusion of Fe cation into the bulk of the tribofilm. The finding that ZDDP tribofilms evolve during rubbing from a weaker amorphous structure to a more durable nanocrystalline one has important implications in terms of the behaviour of ZDDPs at low concentrations, on non-metallic surfaces and at very high contact pressures, as well as for the development of ZDDP tribofilm, friction and wear models.

Published: October 2019

AbstractCommon mental health problems are regarded as public health concerns and can contribute to risky behaviors such as suicide among university students in extreme cases. However, there is a lack of studies concerning such issues in Bangladesh. The present study aimed to fill this knowledge gap by investigating the prevalence and associated risk predictors of depression, anxiety, and stress among Bangladeshi university students. The sample comprised 590 undergraduates attending Jahangirnagar University (Dhaka, Bangladesh) who completed an offline survey including sociodemographic questions, behavioral variables, and the 21-item Bangla Depression, Anxiety and Stress Scale (BDASS-21). The prevalence of moderate to the extremely severe levels of depression, anxiety, and stress was 52.2%, 58.1%, and 24.9%, respectively. There were no significant gender differences in depression, anxiety, and stress. Risk factors for depression included coming from a lower class family, being a cigarette smoker, and engaging in less physical exercise. Risk factors for anxiety and stress included being engaged in a relationship. The findings need to be further replicated among other Bangladeshi university students to help in the development of better intervention programs and appropriate support services targeting this vulnerable group including a focus of suicide prevention and awareness.
A Parametric Study of the Vacuum Arc Remelting (VAR) Process: Effects of Arc Radius, Side-Arcing, and Gas Cooling
Authors: Karimi-Sibaki E. , Kharicha A. , Wu M. , Ludwig A. , Bohacek J. 
Published: October 2019

Abstract
Main modeling challenges for vacuum arc remelting (VAR) are briefly highlighted concerning various involving phenomena during the process such as formation and movement of cathode spots on the surface of electrode, the vacuum plasma, side-arcing, the thermal radiation in the vacuum region, magnetohydrodynamics (MHD) in the molten pool, melting of the electrode, and solidification of the ingot. A numerical model is proposed to investigate the influence of several decisive parameters such as arc mode (diffusive or constricted), amount of side-arcing, and gas cooling of shrinkage gap at mold–ingot interface on the solidification behavior of a Titanium-based (Ti-6Al-4V) VAR ingot. The electromagnetic and thermal fields are solved in the entire system including the electrode, vacuum plasma, ingot, and mold. The flow field in the molten pool and the solidification pool profile are computed. The depth of molten pool decreases as the radius of arc increases. With the decreasing amount of side-arcing, the depth of the molten pool increases. Furthermore, gas cooling fairly improves the internal quality of ingot (shallow pool depth) without affecting hydrodynamics in the molten pool. Modeling results are validated against an experiment.

Published: October 2019

Abstract

Background
Surgical treatment of the stiff elbow can be performed either arthroscopically or via an open approach. There is a paucity of direct prospective comparisons of the techniques in the literature.

Objectives
The aim of the study is to analyze the clinical short-term results of arthroscopic and open elbow arthrolysis in postoperative and posttraumatic stiff elbows.

Materials and methods
The study group consisted of 44 patients divided in two cohorts, one after arthroscopic arthrolysis (33 patients) and the other including patients after open arthrolysis (11 patients). Range of motion (ROM; extension/flexion), pain (numerical rating scale, NRS), as well as the disabilities of the arm, shoulder, and hand (DASH) score were recorded preoperatively and examined in a standardized manner 6 weeks, 3 months, and 6 months after surgery.

Results
In both groups, preoperative elbow movement significantly improved in the follow-up. An increase from 103.3° (±23.4) to 123.5° (±12.5°; p = 0.001) was seen after 6 months for the arthroscopic group, whereas the mean ROM significantly increased from 64.5° (±31.1°) to 100.9° (±25.6°; p = 0.007) following open arthrolysis.
In the arthroscopic group, the DASH score was measured at 37.3 points (±23.4 points) and improved to 16.1 points (±16.5 points) after 6 months, while in the open group it enhanced after 6 months (19.5 points [±17.5 points]) compared to its preoperative value by 38.2 points (±24.1 points). A consistent improvement was found for NRS, which decreased after surgery in both groups (arthroscopic group = −3.1 [±3.0]; open group = −2.0 [±2.9]). Complications did not occur in either group. When comparing delta values of the groups between the preoperative ROM, DASH score, and NRS, no significant differences were observed (p < 0.05).

Conclusions
Good to excellent functional recovery was seen in both cohorts when evaluating for improvement in the DASH score, the gain in elbow motion, and the decrease in pain. No significant differences were found between the procedures regarding pre- and postoperative measurements. The arthroscopic approach has developed to become an effective alternative to treat posttraumatic elbow stiffness.

Abstract
Mutations in LRRK2 are currently recognized as the most common monogenetic cause of Parkinsonism. The elevation of kinase activity of LRRK2 that frequently accompanies its mutations is widely thought to contribute to its toxicity. Accordingly, many groups have developed LRRK2-specific kinase inhibitors as a potential therapeutic strategy. Given that protein phosphorylation is a reversible event, we sought to elucidate the phosphatase(s) that can reverse LRRK2-mediated phosphorylation, with the view that targeting this phosphatase(s) may similarly be beneficial. Using an unbiased RNAi phosphatase screen conducted in a Drosophila LRRK2 model, we identified PP2A as a genetic modulator of LRRK2-induced neurotoxicity. Further, we also identified ribosomal S6 kinase (S6K), a target of PP2A, as a novel regulator of LRRK2 function. Finally, we showed that modulation of PP2A or S6K activities ameliorates LRRK2-associated disease phenotype in Drosophila.

AbstractEstuaries in the northern Gulf of Mexico (GOM) provide habitat for many ecologically, commercially, and recreationally important fish and crustacean species (i.e., nekton), but patterns of nekton abundance and community assemblages across habitat types, salinity zones, and seasons have not been described region-wide. Recognizing the wealth of information collected from previous and ongoing field sampling efforts, we developed a meta-analytical approach to aggregate nekton density data from separate studies (using different gear types) that can be used to answer key research questions. We then applied this meta-analytical approach to separate nekton datasets from studies conducted in the Gulf of Mexico to summarize patterns in nekton density across and within several estuarine habitat types, including marsh, oyster reefs, submerged aquatic vegetation (SAV), and open-water non-vegetated bottom (NVB). The results of the meta-analysis highlighted several important patterns of nekton use associated with these habitat types. Nekton densities were higher in structured estuarine habitats (i.e., marsh, oyster reefs, SAV) than in open-water NVB habitat. Marsh and SAV community assemblages were relatively similar to each other, but different from those associated with open-water NVB and oyster habitats. Densities of commercially and recreationally important crustacean and fish species were highest in saline marshes, thus demonstrating the importance of this habitat in the northern GOM. The results of our meta-analysis are generally consistent with previous site-specific studies in the region (many of which were included in the meta-analysis) and provide further evidence for these patterns at a regional scale. This meta-analytical approach is easy to implement for diverse research and management purposes, and provides the opportunity to advance understanding of the value and role of coastal habitats to nekton communities.

Published: October 2019

Abstract
The Tista is a Trans-Himalayan river that flows through Sikkim and West Bengal states of India and Rangpur division of Bangladesh and finally falls into the Brahmaputra River. The presence of numerous abandoned channels with various degrees of aggradations indicates large migrations of the Tista River. The pH value of groundwater varies from 6.20 to 7.40 which indicate the slightly alkaline to acidic nature of the studied aquifers. The mean abundance of major cations is Na+ > Ca+2 > Mg+2 > K+, whereas the major anions is HCO3− > Cl− > SO4−2. Among the cations, Na+ is the dominant and K+ is the lowest constituents, whereas HCO3− is most abundant and SO4−2 is the minor constituents in anions. The hydrochemical facies of groundwater show that sodium, sodium–magnesium, sodium–calcium, sodium–magnesium–calcium and sodium–calcium–magnesium are cation facies and chloride–bicarbonate, bicarbonate–chloride and bicarbonate are anion facies. Correlating with WHO (Guidelines for drinking-water quality, 1, World Health Organisation, Geneva, 1997) and EQS (Environmental quality standard, Department of Environment, Bangladesh, 1989) guideline values for drinking water and public health, it may be concluded that the groundwater of the study area is suitable for all drinking and domestic purposes, where only three samples exceed the maximum allowable limit of potassium. Based on total hardness, SAR, RSC, PI, SSP and MH values, it can be summarized that the groundwater of the investigated area is suitable for irrigation purpose. On the basis of Australian and UNESCO standard, the groundwater of the study area is also suitable for livestock purposes. The Rangpur area is hydrogeologically active by the processes like ion exchange and dissolution. Ca2+, Mg2+ and HCO3− are produced by the dissolution of limestone and dolomite.
A review of critical perspectives on private land conservation in academic literature
Authors: Gooden Jennifer , ‘t Sas-Rolfes Michael 
Published: October 2019

AbstractIn recent years, private land conservation has increased in profile among policymakers and academics. Conservation initiatives on privately owned land help to mitigate global biodiversity loss and introduce new actors to conservation. However, they have also been the subject of numerous critical accounts. This review catalogs issues that emerge in critical literature, identifying 25 themes, classified into three groups: Implementation Effectiveness, Value Conflict, and Economic Inefficiency. Gaps in the literature include the need for broader geographic coverage; assessment of the issues’ specificity to private land conservation; and evaluation of the extent to which issues in the literature reflect broader societal values. The literature’s strong emphasis on value conflict suggests that greater attention to governance effectiveness may steer private land conservation toward practices that are more just, equitable, and representative and lead to increased societal support. We recommend further research to address identified gaps, with a greater orientation toward inclusive governance.
The effect of previous treatment with bisphosphonate and renal impairment on the response to denosumab in osteoporosis: a ‘real-life’ study
Authors: Fraser T. R. , Flogaitis I. , Moore A. E. , Hampson G. 
Published: October 2019

Abstract

Purpose
To investigate changes in bone mineral density (BMD) following denosumab after previous bisphosphonate therapy and the impact of chronic kidney disease (CKD) on response.

Methods
A retrospective study of 134 patients (11 M, 123 F) aged [mean (SD)] 72 [11] years on denosumab was undertaken. Ninety-five patients had previously been on oral and 28 on iv bisphosphonate. Lumbar spine (LS), total hip (TH) and femoral neck (FN) BMD were measured before treatment and at 2.7 [1.2] years. GFR was < 35 ml/min in 24 patients (18%). Ninety-four (18 M, 76 F) patients aged 71 [11] years transitioning to zoledronate were also studied.

Results
BMD improved following denosumab [mean (SEM) % change LS: 6.0 (0.62) p < 0.001, TH: 2.28 (0.64) p < 0.001, FN: 1.9 (0.77) p = 0.045]. Changes at the TH and FN were lower in patients with GFR < 35 ml/min (Group B) compared to those with GFR > 35 ml/min (Group A) [% change TH; Group A: 2.9 (0.72), Group B: − 0.84 (1.28), p = 0.015, FN; Group A: 2.76 (0.86), Group B: − 1.47 (1.53), p = 0.025]. % change in BMD at the FN and PTH were negatively associated (r = − 0.25, p = 0.013). BMD changes were not different at 12–18 months between patients on denosumab compared to zoledronate [% change at LS: denosumab: 3.97% (0.85), zoledronate: 2.6% (0.5), p = 0.19 TH: denosumab: 0.97% (0.58), zoledronate: 0.92% (0.6), p = 0.95).

Conclusion
Denosumab increases BMD following previous bisphosphonate treatment and is comparable to zoledronate. Lower response seen at the hip in CKD is related to PTH concentrations.
Understanding plagiarism in Indonesia from the lens of plagiarism policy: lessons for universities
Authors: Akbar Akbar , Picard Michelle 
Published: October 2019

AbstractPlagiarism is viewed as a critical issue that can hinder the development of creativity and innovation in Indonesia. Thus, since the early 2000s the Indonesian government has endeavoured to develop policies to address this issue. In response to national policy, Indonesian educational institutions have made serious institutional efforts to address the plagiarism issue. Research in the Indonesian Higher education context on plagiarism has focussed on reporting prevention and mitigation efforts. However, little has been discussed about the communication of these efforts in policy across the different institutional levels of Indonesian Higher Education. This study aims at exploring the anti-plagiarism efforts by determining the main features (or discourses) reflected in plagiarism policy in Indonesian HE from national to institutional level. Two web-based resources namely the official website of The General Directorate of Research, Technology and Higher Education (retrieved 2015), and the website of Bandung Institute of Technology (retrieved 2015) were used to ascertain the most appropriate policies to include in the study. Critical Discourse Analysis (CDA) was used to reach explanatory understanding of how the policies (discursive events) demonstrate through their linguistic repetitions and other forms intertextuality, their relative positions within the Indonesian Higher Education institutional hierarchy and consequently provide some insight into the social practices and understandings of plagiarism underlying the creation of the documents. This study revealed that perhaps because of the rigid boundaries and hierarchies represented between the documents, the university policy does not show much transformation from the documents at a Ministry level, hence the definition of plagiarism remains broad and the levels of plagiarism and sanctions for plagiarism remain undefined. This can potentially lead to inconsistencies in developing effective practices preventing plagiarism.

Authors: Škrlj Blaž , Kralj Jan , Lavrač Nada 
Published: October 2019

AbstractComplex networks are used as means for representing multimodal, real-life systems. With increasing amounts of data that lead to large multilayer networks consisting of different node and edge types, that can also be subject to temporal change, there is an increasing need for versatile visualization and analysis software. This work presents a lightweight Python library, Py3plex, which focuses on the visualization and analysis of multilayer networks. The library implements a set of simple graphical primitives supporting intra- as well as inter-layer visualization. It also supports many common operations on multilayer networks, such as aggregation, slicing, indexing, traversal, and more. The paper also focuses on how node embeddings can be used to speed up contemporary (multilayer) layout computation. The library’s functionality is showcased on both real and synthetic networks.

Abstract
The melon fruit fly, Zeugodacus cucurbitae (Coquillett) is a quarantine insect pest worldwide and affects the vegetable quality through its direct feeding and indirectly by passing way for secondary pathogens. This study investigated the host susceptibility, preference and offspring performance of Z. cucurbitae under the laboratory conditions. Different vegetable hosts i.e., brinjal (Solanum melongena L.), bitter gourd (Momordica charantia L.), zucchini (Cucurbita pepo L.), bottle gourd (Lagenaria siceraria [Molina] Standley) and cucumber (Cucumis sativus L.) were tested under no choice and free choice tests. Results showed that C. sativus and C. pepo have highest number of visits/host and oviposition puncture/host. C. sativus showed highest pupal recovery and pupal weight in both only choice and free choice test. While, highest percentage of emergence and female off springs were observed in C. pepo under only choice and free choice scenarios. Furthermore, maximum deformities in progeny were observed in case of L. siceraria under both test case scenarios. The current study provides exploratory support that fruit flies respond differently to host species that co-exists in field under choice and no choice test. Further, hosts of advantage to fruit flies are adopted more. The host and choice preference of fruit flies have the influence on the pest management strategies for the vegetable crops.
