HERIYANTO, N. M., SAMSOEDIN, I. & KARTAWINATA, K. 2018. Tree species diversity, structural characteristics and carbon stock in a one-hectare plot of the protection forest area in West Lampung Regency, Indonesia. Reinwardtia 18(1): 1‒18. — A study of species composition, structure and carbon stock in the lower montane forest in the Register 45B of the protection forest area in the Tri Budi Syukur District, Kebun Tebu Village, West Lampung Regency, Lampung Province was conducted in September 2016. The objective of the study was to undertake quantified measurements of floristic composition and structure of and carbon storage in the lower montane forest at 965 m asl in the protection forest area. A one hectare plot (100 m × 100 m) was established randomly. The plot was further divided into 25 subplots of 20 m × 20 m each to record trees. Quadrats of 5 m × 5 m for saplings and subquadrats of 2 m × 2 m for seedlings were nested in the tree subplots. We recorded 247 trees with diameter at breast height ≥ 10 cm representing 25 species and 19 families, with a total basal area of 59.14 m2. Overall including seedlings and saplings we recorded 31 species. The species richness was very low due to disturbances, and was the lowest compared to that of other forests in Sumatra, Kalimantan and Java. The dominant species in terms of importance values (IV) were Litsea cf. fulva (IV=77.02), Lithocarpus reinwardtii (IV=45.21) and Altingia excelsa (IV=26.95). Dominant species in seedling and sapling stages were Polyalthia lateriflora (IV=27.54) and Memecylon multiflorum (IV=41.58). Biomass and carbon stock of trees with DBH ≥ 10 cm was 50.87 ton/ha and 25.43 ton C/ha, respectively. Regeneration was poor. Structurally and floristically the forest was a developing disturbed forest and the composition will remain unchanged in many years to come. The successions leading to terminal communities similar to the original conditions would be very slow and should be assisted and enhanced by applying ecological restoration through planting tree species native to the site.

Published: July 2019

Abstract
Based on the previously published researches of the phenomenon of populism and its presence in the Republic of Croatia, and using methodological contents analyis matrix, which has been developed by B. Šalaj and M. Grbeša Zenzerović, this paper deals with the research of the presence of populism in the early Parliamentary election held in 2016. The researches of the phenomenon of populism have been intensified on both local and global level, and populism, as a concept, is becoming increasingly present in social and political discourse. However, everyone and everything is then easily classified as populistic. In the context of the Republic of Croatia, which has been through numerous state orders throughout its political history, this paper is going to examine if there was populism, as an aspect of political action, in the 2016 elections, and it is going to potentially identify the political actors, who have been using populistic features in their political careers. Furthermore, it is going to examine which kind of populism it is.

Published: July 2019

Abstract
In autonomous driving, prediction tasks address complex spatio-temporal data. This article describes the examination of Recurrent Neural Networks (RNNs) for object trajectory prediction in the image space. The proposed methods enhance the performance and spatio-temporal prediction capabilities of Recurrent Neural Networks. Two different data augmentation strategies and a hyperparameter search are implemented for this purpose. A conventional data augmentation strategy and a Generative Adversarial Network (GAN) based strategy are analyzed with respect to their ability to close the generalization gap of Recurrent Neural Networks. The results are then discussed using single-object tracklets provided by the KITTI Tracking Dataset. This work demonstrates the benefits of augmenting spatio-temporal data with GANs.

Authors: Kumar Ghanendra , Kumar Chakresh 
Published: July 2019

Abstract
In the last decade, huge development has been seen in the field of wireless communication. The performance depends on the shape and size of the antenna. The future aim of wireless communication is to provide data with high speed data range even in harsh geographical areas. Here aim is to design and compare the E and H slot, T-slot, O-slot and U-slot antenna. The designed patch antenna operates at a frequency of 60 GHz with maximum antenna gain and minimum radiation loss using high frequency structure simulator (HFSS). We will use Rogers RT/duroid 5880 as substrate due to its suitable mechanical and insulating properties. Resonant frequency used will be 60 GHz and height will be 1.6 mm, 1.57 mm, 1.6 mm and 0.508 mm for E and H slot, T-slot, O-slot and U-slot, respectively.
A hybrid random forest to predict soccer matches in international tournaments
Authors: Groll Andreas , Ley Cristophe , Schauberger Gunther , Van Eetvelde Hans 
Published: July 2019

Abstract
In this work, we propose a new hybrid modeling approach for the scores of international soccer matches which combines random forests with Poisson ranking methods. While the random forest is based on the competing teams’ covariate information, the latter method estimates ability parameters on historical match data that adequately reflect the current strength of the teams. We compare the new hybrid random forest model to its separate building blocks as well as to conventional Poisson regression models with regard to their predictive performance on all matches from the four FIFA World Cups 2002–2014. It turns out that by combining the random forest with the team ability parameters from the ranking methods as an additional covariate the predictive power can be improved substantially. Finally, the hybrid random forest is used (in advance of the tournament) to predict the FIFA World Cup 2018. To complete our analysis on the previous World Cup data, the corresponding 64 matches serve as an independent validation data set and we are able to confirm the compelling predictive potential of the hybrid random forest which clearly outperforms all other methods including the betting odds.

Abstract
Homopolymer bulk hydrogel of methacrylic acid was synthesized through a new single-step facile rout and used as a template for the fabrication of nickel (Ni) nanoparticles and as adsorbent to remove methylene blue (MB) and Rhodamine-6G (Rh-6G) from water. The Ni nanoparticles containing composite hydrogel was applied as catalyst for the degradation of a nitro compound. The carboxylic groups acted as highly efficient adsorption sites and their high degree was responsible for the removal of huge amounts of MB and Rh-6G from water. The maximum adsorption capacity of poly (methacrylic acid) hydrogel was 685 mg g−1 for MB and 1571 mg g−1 for Rh-6G. The adsorption data of MB was best fitted with Langmuir adsorption isotherm while that of Rh-6G with Temkin adsorption isotherm. Catalytic property of prepared hydrogel integrated with Ni nanoparticles was evaluated by using it as a catalyst for the degradation of 4-nitrophenol (4-NP). The apparent rate constant (k
app) observed in this study for the reduction of 4-NP was as high as 0.038 min−1. It was found that this catalyst system can be used repetitively with a slight decrease in catalytic activity.
Bin ich meines Glückes Schmied?

Published: July 2019

Zusammenfassung:
Gemäß der These der Selbstwertdienlichkeit internaler Attributionen wird untersucht, ob der persönliche Berufserfolg und die soziale Mobilität mit dem Anstieg des Berufserfolgs stärker der Person und weniger den externen Umständen zugeschrieben werden. Datenbasis ist eine Wiederbefragung von im 16. Lebensjahr erstmals befragten Gymnasiasten im 30., 43. und 56. Lebensjahr. Der Berufserfolg wird als Prestigegewinn, Einkommenssteigerung und Einschätzung des aktuellen beruflichen Erfolgs im Vergleich zum Berufsbeginn erhoben. Die Hypothesen werden mit Strukturgleichungsmodellen getestet, die unbeobachtete Heterogenität durch einen Faktor für jede Person kontrollieren. Zu keinem Zeitpunkt trifft zu, dass der Berufserfolg zugleich seine internale Attribution steigert und seine externale Attribution senkt; dasselbe gilt für die Attribution der Mobilität. Aber die Attributionen sind stabil und beeinflussen einander negativ; und beides wird im Lebenslauf stärker.
Experimental Validation of a New Antivibration Elastomeric Material Fabricated from End-of-Life Tires for Slab Track Systems with Embedded Rail
Authors: Gómez Jorge , Casado José Antonio , Carrascal Isidro A. , Diego Soraya , Ferreño Diego , Mondragón Catalina 
Published: July 2019

Abstract
This article is focused on the experimental characterization and validation of a novel elastomeric material fabricated from the grinded end-of-life tires blended with polyurethane resin. This material will be used as a vibration and noise attenuator in railway slab track systems with embedded rail, commonly used in urban areas. Cylinders with different combinations of grain sizes (coarse, medium, and fine) of end-of-life tires and contents of resin were mechanically tested to obtain the Young’s modulus. The most versatile combination consisting in 50 % coarse + 50 % medium size grains was selected. Two real-scale prototypes consisting of a rail surrounded by the rubber mixture and the concrete slab were designed and fabricated to be applied under normal conditions (low attenuation system) and under situations where vibrations could be fatal (high attenuation system). These prototypes were subjected to static, dynamic, and fatigue loading conditions, applying vertical and angular loads, to validate their mechanical performance. In addition, a vibroacustical experimental study was carried out to obtain the frequency response and the receptance functions. A one-degree-of-freedom analytical model was developed to obtain a loss factor η = 0.287 and a vibration attenuation capacity of the system for the human ear peak sensitivity of ∼40 dB. This study proves the validation of this new eco-friendly material to be used as a vibration attenuator for railway traffic.
Discrete Element Methods for Characterizing the Elastic Behavior of the Granular Particles
Authors: Ding Xunhao , Ma Tao , Gu Linhao , Zhang Deyu , Huang Xiaoming 
Published: July 2019

Abstract
Focusing on characterizing the elastic behavior of the granular particles based on the discrete element method (DEM), this study utilized the Mustoe and Griffiths’ equations and a homogenization method to predict the performance of the continuous elastic medium precisely, including the elastic modulus, Poisson’s ratio, and the brittle fracture criterion. A commercial DEM software named Particle Flow Code in Two Dimensions (PFC2D) was used to conduct the numerical simulations because the macrobehavior predicted by the PFC2D highly depends on the sphere size and arrangements. The hexagonal parking arrangements were applied further herein for better theoretical calculations. With the combined analysis of the discontinuum theory and continuum theory, the DEM parameters were determined theoretically and were verified based on the virtual compression and tension tests. The factors (including sphere size, stiffness ratios, etc.) influencing the prediction accuracy were also analyzed further. The results showed that by the parameter determination methods proposed in this study, the behavior of the continuous elastic medium could be well characterized.

Published: July 2019

Abstract
The requirements for modified asphalt concrete are increasing because of heavy traffic load and worsening service environments in modern highway construction. More and more attention has been paid to the development of multifunctional asphalt concrete. Conductive asphalt concrete exhibits specific characteristics and incredible novel features, such as self-diagnosis and monitoring, self-healing, and snowmelt, etc. It has the potential to satisfy multifunctional applications. This article summarizes the major achievements of the existing literatures about conductive asphalt concrete, including material design, mechanism analysis, performance evaluation and engineering applications, and gives some proposals for further investigations. The article shows that the conductivity and mechanical properties of conductive asphalt concrete are strongly dependent on the compositions of the material. Meanwhile, the mechanism of conductivity improvement is identified according to the characteristics of conductive additives. Although conductive asphalt concrete has some shortcomings and few applications in the highway industry, it shows some appreciable advantages in aspects such as environment protection and traffic safety. The purpose of this review article is to provide the reference and guidance for researchers to discover proper material design, novel properties, durability, and desirable high operational efficiency, as well as suitable construction technique.

Published: July 2019

BACKGROUND AND OBJECTIVE:
Children with special health care needs (SHCNs) have significant medical and educational expenses affecting household finances. Housing instability can be detrimental to family well-being. Our objective was to evaluate housing instability in households of children with and without SHCNs.

METHODS:
Cross-sectional surveys (2013–2017) in English and Spanish of caregivers with children &lt;4 years old were conducted at 5 hospitals. The children with SHCN screener and caregiver report of child Supplemental Security Income (SSI) receipt were used to categorize children into the following groups: (1) no SHCNs, (2) SHCNs and no SSI, or (3) SHCNs and receiving SSI. Housing instability was determined by positive endorsement of ≥1 adverse circumstance: behind on rent or mortgage, or moving twice or more in the past year, or homelessness in the child’s lifetime. Analyses used multivariable logistic regression models, adjusting for demographics and housing subsidies.

RESULTS:
Of 14 188 children, 80% had no SHCNs, 16% had SHCNs and no SSI, and 4% had SHCNs and received SSI. Compared with the no-SHCNs group, the SHCNs–no-SSI group but not the SHCN–receiving-SSI group experienced significantly greater adjusted odds of being behind on rent or mortgage (adjusted odds ratio [aOR] 1.28 [95% confidence interval (CI) 1.14–1.44]; P &lt; .001), multiple moves (aOR 1.29 [95% CI 1.05–1.59]; P = .01), and homelessness (aOR 1.44 [95% CI 1.20–1.72]; P &lt; .001).

CONCLUSIONS:
Families of children with SHCNs are at risk for housing instability. Child SSI receipt decreased the risk of housing instability among families of children with SHCNs. Protecting families of young children with SHCNs from housing instability is an important investment.

Authors: Scott Vanessa P. , Opel Douglas J. , Reifler Jason , Rikin Sharon , Pethe Kalpana , Barrett Angela , Stockwell Melissa S. 
Published: July 2019

OBJECTIVES:
To assess the impact of a parent educational intervention about influenza disease on child vaccine receipt.

METHODS:
A convenience sample of parents of children ≥6 months old with a visit at 2 New York City pediatric clinics between August 2016 and March 2017 were randomly assigned (1:1:1) to receive either usual care, an educational handout about influenza disease that was based on local data, or an educational handout about influenza disease that was based on national data. Parents received the handout in the waiting room before their visit. Primary outcomes were child influenza vaccine receipt on the day of the clinic visit and by the end of the season. A multivariable logistic regression was used to assess associations between intervention and vaccination, with adjustment for variables that were significantly different between arms.

RESULTS:
Parents who received an intervention (versus usual care) had greater odds of child influenza vaccine receipt by the end of the season (74.9% vs 65.4%; adjusted odds ratio 1.68; 95% confidence interval: 1.06–2.67) but not on the day of the clinic visit. Parents who received the national data handout (versus usual care) had greater odds of child influenza vaccine receipt on the day of the clinic visit (59.0% vs 52.6%; adjusted odds ratio 1.79; 95% confidence interval: 1.04–3.08) but not by the end of the season.

CONCLUSIONS:
Providing an educational intervention in the waiting room before a pediatric provider visit may help increase child influenza vaccine receipt.

Groups with restrictions on proper uncountable subgroups
Authors: De Giovanni Francesco , Trombetti Marco 
Published: July 2019

Abstract
A group G is called metahamiltonian if all its non-abelian subgroups are normal. The aim of this paper is to investigate the structure of uncountable groups of cardinality ℵ in which all proper subgroups of cardinality ℵ are metahamiltonian. It is proved that such a group is metahamiltonian, provided that it has no simple homomorphic images of cardinality ℵ. Furthermore, the behaviour of elements of finite order in uncountable groups is studied in the second part of the paper.

Authors: Leslie William D. , Morin Suzanne N. , Lix Lisa M. , Niraula Saroj , McCloskey Eugene V. , Johansson Helena , Harvey Nicholas C. , Kanis John A. 
Published: July 2019

Abstract

Background
Aromatase inhibitors (AIs) used in breast cancer induce loss in bone mineral density (BMD) and are reported to increase fracture risk.

Materials and Methods
Using a population-based BMD registry, we identified women aged at least 40 years initiating AIs for breast cancer with at least 12 months of AI exposure (n = 1,775), women with breast cancer not receiving AIs (n = 1,016), and women from the general population (n = 34,205). Fracture outcomes were assessed to March 31, 2017 (mean, 6.2 years for AI users).

Results
At baseline, AI users had higher body mass index (BMI), higher BMD, lower osteoporosis prevalence, and fewer prior fractures than women from the general population or women with breast cancer without AI use (all p &lt; .001). After adjusting for all covariates, AI users were not at significantly greater risk for major osteoporotic fractures (hazard ratio [HR], 1.15; 95% confidence interval [CI], 0.93–1.42), hip fracture (HR, 0.90; 95% CI, 0.56–1.43), or any fracture (HR, 1.06; 95% CI, 0.88–1.28) compared with the general population.

Conclusion
Higher baseline BMI, BMD, and lower prevalence of prior fracture at baseline may offset the adverse effects of AI exposure. Although confirmatory data from large cohort studies are required, our findings challenge the view that all women with breast cancer initiating AI therapy should be considered at high risk for fractures.

Implications for Practice
In a population-based observational registry that included 1,775 patients initiating long-term aromatase inhibitor therapy, risk for major osteoporotic fracture, hip fracture, or any fracture was similar to the general population. Higher baseline body mass index, bone mineral density, and lower prevalence of prior fracture at baseline may offset the adverse effects of aromatase inhibitor exposure.
