Authors: Khotimah N. 
Published: July 2019

Abstract
The Imogiri Subdistrict area has plain, hills and mountain topography which have varied land conditions. The varied land conditions are mostly used for agricultural land. In increasing agricultural production, the farming community in Imogiri Sub-district made efforts to conserve their land. This condition creates a phenomenon that exists in the farming community, namely conservative behavior towards the agricultural land they have in order to increase their agricultural production. The purpose of this study was to determine: (1) the characteristics of agricultural land in each landscape of Imogiri Subdistrict, and (2) the conservative behavior of farming communities in each landscape in the use and management of agricultural land addressing the existing land conditions. The design of this research is quantitative descriptive research. The population of this study was all farmers in Imogiri Subdistrict. The study sample was determined by quota, which is 50 farmers for each landscape, so the total sample was 150 people. The sampling technique is done with randomly. The research data was collected through observation, interviews, and documentation. The data collected then tabulated and analyzed descriptively. The results showed that: (1) characteristics of agricultural land: (a) plains dominated by irrigated fields, paddy-paddy-paddy cropping patterns, availability of sufficient water, sources of water from rivers, dominant types of agricultural crops in the form of paddy, (b) hilly dominated by rainfed / dry land, paddy-paddy-palawija cropping patterns, availability of sufficient water, sources of water from rivers and rain, dominant types of agricultural crops in the form of paddy and palawija, (c) mountainous dominated by rainfed paddy fields / dry land, patterns planting paddy-palawija-tobacco, the availability of insufficient / less water, sources of water from rain, dominant types of agricultural crops in the form of paddy, palawija, and tobacco, (2) the conservative behavior of farmers in each landscape varies in intensity; efforts are made to intensify planting and increase production, maintain fertility of paddy fields and care for plants, prevent possible damage to paddy fields due to flooding and drought, and apply mechanical / vegetative conservation methods.
Understanding geomorphological hazard in Watumalang Area post Bisma volcanic era. Denudational or multihazard?
Authors: Ashari A. 
Published: July 2019

Abstract
The combination of endogenous processes in the form of volcanic and mountainous formation with exogenous processes in the form of wet tropical climate produces very complex geomorphological conditions in Java. From this geomorphological complexity there are various kinds of processes that often cause disasters for people’s lives. Watumalang Area in Wonosobo Regency, is one of the regions in Java Island with complex geomorphological conditions. Based on the genesis, this region was formed by volcanic activity in the past, some of which were affected by the structural process. Bisma Volcano is the last part of volcanism in this region that has stopped since thousands of years ago. At this time landform denudation is a dominating process and causes many disasters. However, does the threat of hazard only come from the denudation process? This paper aims to identify the geomorphological conditions of the Watumalang Area and the potential hazard. To achieve these objectives field observations were carried out using geomorphological survey methods. Observations are supported by remote sensing image interpretation, study literature, and documentation. Spatial analysis with a geomorphological approach supported by GIS analysis was used to describe the geomorphological hazard distribution. The results show that the Watumalang area is geomorphologically arranged by structural and volcanic units. The denudation process is so dominant that the potential for geomorphological hazards comes mainly from this process. However, the presence of faults can also trigger earthquakes. Meanwhile the existence of Bisma Volcano which is currently not active does not act as a trigger. In areas with such complex geomorphological conditions, the multihazard approach needs to be prioritized rather than limited to one type of hazard, although one hazard has a tendency to be more dominant.

Validity of Gross–Pitaevskii solutions of harmonically confined BEC gases in reduced dimensions

Published: July 2019

Abstract
By exact numerical solutions of the Gross–Pitaevskii (GP) equation in 3D, we assess the validity of 1D and 2D approximations in the study of Bose–Einstein condensates confined in harmonic trap potentials. Typically, these approximations are performed when one or more of the harmonic frequencies are much greater than the remaining ones, using arguments based on the adiabatic evolution of the initial approximated state. Deviations from the 3D solution are evaluated as a function of both the effective interaction strength and the ratio between the trap frequencies that define the reduced dimension where the condensate is confined. The observables analyzed are both of stationary and dynamical character, namely, the chemical potential, the wave function profiles, and the time evolution of the approximated 1D and 2D stationary states, considered as initial states in the 3D GP equation. Our study, besides setting quantitative limits on approximations previously developed, should be useful in actual experimental studies where quasi-1D and quasi-2D conditions are assumed. From a qualitative perspective, 1D and 2D approximations certainly become valid when the anisotropy is large, but in addition the interaction strength needs to be above a certain threshold.
Nonsteady-state processes in a low-current discharge in airflow and formation of a plasma jet

Published: July 2019

Abstract
The paper describes the investigations of a low-current discharge in airflow with the electrode configuration of coaxial plasmatron. An inner diameter of the plasmatron nozzle is of 0.5 cm and the mass airflow rate is from 0.1 to 0.3 g s−1. Typical averaged discharge current is varied from 0.06 to 0.2 A. In these conditions, due to airflow the so-called plasma jet forms in the plasmatron nozzle and at its exit. The total current in plasmatron mainly flows via the constricted plasma column of the glow discharge and only a small fraction of current is carried by the jet. The principal idea of the experiments is to reveal the mechanism of the jet formation and to elucidate how the nonsteady discharge regimes influence on the jet properties. We have proposed the method for the jet diagnostics, which is based on measuring the currents to the additional diagnostic electrodes located outside the nozzle. The obtained data show that the jet current forms due to electrons that are emitted from the boundary of plasma column. The temporal behavior of the jet current is determined by the position of the column inside the plasmatron nozzle, which changes with time. Hence, the term ‘plasma jet’ has to be used with care, since the charged particles in the jet area are the electrons. The estimated electron density in the jet is of about 109 cm–3.

Abstract
MCViNE is an open source, object-oriented Monte Carlo neutron ray-tracing simulation software package. Its design allows for flexible, hierarchical representations of sophisticated instrument components such as detector systems, and samples with a variety of shapes and scattering kernels. Recently this flexible design has enabled several applications of MCViNE simulations at the Spallation Neutron Source (SNS) at Oak Ridge National Lab, including assisting design of neutron instruments at the second target station and design of novel sample environments, as well as studying effects of instrument resolution and multiple scattering. Here we provide an overview of the recent developments and new features of MCViNE since its initial introduction (Jiao et al 2016 Nucl. Instrum. Methods Phys. Res., Sect. A 810, 86–99), and some example applications.
Natural Hamiltonian formulation of composite higher derivative theories
Authors: Öttinger Hans Christian 
Published: July 2019

Abstract
If a higher derivative theory arises from a transformation of variables that involves time derivatives, a tailor-made Hamiltonian formulation is shown to exist. The details and advantages of this elegant Hamiltonian formulation, which differs from the usual Ostrogradsky approach to higher derivative theories, are elaborated for mechanical systems and illustrated for simple examples. Both a canonical space and a set of constraints emerge naturally from the transformation rule for the variables. In other words, the setting for quantization and the procedure for eliminating instabilities arise naturally.

Published: July 2019

Abstract
The high theoretical capacity of Li-O2 batteries attracts a lot of attention and this field has expanded significantly in the last two decades. In a more general way, the large number of articles being published daily makes it difficult for researchers to keep track of the progress in science. Here we develop a text mining program in an attempt to facilitate the process of reviewing the literature published in a scientific field and apply it to Li-O2 batteries. We analyze over 1800 articles and use the text mining program to extract reported discharge capacities, for the first time, which allows us to show the clear progress made in recent years. In this paper, we focus on three main challenges of Li-O2 batteries, namely the stability-cyclability, the low practical capacity and the rate capability. Indeed, according to our text mining program, articles dealing with these issues represent 86% of the literature published in the field. For each topic, we provide a bibliometric analysis of the literature before focusing on a few key articles which allow us to get insights into the physics and chemistry of such systems. We believe that text mining can help readers find breakthrough papers in a field (e.g. by identifying papers reporting much higher performances) and follow the developments made at the state of the art (e.g. by showing trends in the numbers of papers published—a decline in a given topic probably being the sign of limitations). With the progress of text mining algorithms in the future, the process of reviewing a scientific field is likely to become more and more automated, making it easier for researchers to get the ‘big picture’ in an unfamiliar scientific field.

Support for Solitary Bee Conservation among the Public versus Beekeepers
Authors: Penn Jerrod , Hu Wuyang , Penn Hannah J. 
Published: July 2019

AbstractThe decline of European honey bees (Apis mellifera) has been a prominent part of supporting pollinator conservation among the public and conservation efforts, even while honey bees are not native to North America and may compete for resources with native insect pollinators. However, little is known about what distinguishes support for native insect pollinators, including solitary bees, the majority of native bees, which provides use and non‐use values distinct from honey bees even though some natives have faced even more precipitous die‐offs. Using data collected from the general public and beekeepers in Louisiana, we adopt a contingent valuation method to investigate the value of conserving solitary bees. Results suggest modest to moderate positive willingness to pay for solitary bee conservation, and possibly higher willingness to pay among honey beekeepers versus the general public. Significant heterogeneity exists between the general public and beekeepers in terms of their knowledge and attitudes of honey bees and other pollinators.

Published: July 2019

Abstract

BACKGROUND
Relationships between blood glucose (BG) levels and insulin action, and incidence of hypertension have not been well known epidemiologically. This study aimed to investigate the association between indices of diabetes and the incidence of hypertension and compare the predictive powers of these indices in middle-aged Japanese.

METHODS
This 5-year cohort study included 2,210 Japanese aged 30–64 years without hypertension. Hazard ratios of high fasting blood glucose (FBG) levels, high post-loaded BG levels, high glycated hemoglobin (HbA1c) levels, insulin resistance (defined by homeostasis model assessment of insulin resistance [HOMA-IR]) and impaired insulin secretion at baseline for the incidence of hypertension were estimated using multivariable-adjusted Cox proportional hazard models. Hypertension was defined as blood pressure ≥ 140/90 mm Hg or receiving antihypertensive treatment.

RESULTS
During the follow-up, 456 participants developed hypertension. After adjustment for HbA1c and HOMA-IR, FBG was independently and significantly associated with hypertension. The hazard ratio of participants with FBG ≥ 7.0 mmol/l was 1.79 compared with those with FBG &lt; 5.6 mmol/l. Even among those with HbA1c &lt; 6.5%, HOMA-IR &lt; 2.5, body mass index &lt; 25 kg/m2, age &lt; 55 years old, blood pressure &lt; 130/80 mm Hg or non- and moderate drinking, the results were similar. High 120-minute BG level and impaired insulin secretion did not increase the risk for hypertension.

CONCLUSIONS
FBG was a predictable index for future incidence of hypertension in middle-aged Japanese men and women. This is the first study comparing predictive powers of indices of diabetes for the incidence of hypertension.
Direct Comparison of Multidimensional Clinical Assessment Tools: Sensitivity to Concussion in Student Athletes

Published: July 2019

Abstract

Purpose
Consensus guidelines recommend multidimensional assessment for concussion diagnosis and management. Among cognitive, oculomotor, and postural stability, it remains unclear which modalities perform best in the acute/subacute periods. We conducted a direct comparison to identify those with the strongest sensitivity to sport-related concussion.

Methods
High school and collegiate football players (aged 14–24) completed preseason baseline assessments. Concussed (n=91) and matched non-concussed teammates (n=85) underwent repeat testing at 48 hours, 8 days, and 15 days post-injury. Postconcussive symptoms (SCAT-3 symptom severity), cognition (Standardized Assessment of Concussion, Immediate Post-Concussion and Cognitive Testing, Trail Making Test, Wechsler Adult Intelligence Scale-IV Processing Speed Index), oculomotor functioning (King-Devick Test), and postural stability (Balance Error Scoring System) were compared using Cohen’s d and Receiver Operating Characteristic analyses.

Results
Symptom severity had the greatest sensitivity at 48 hours and 8 days post-injury (Cohen’s d=1.43 and 0.53, AUC=.93 and .63, p<.01). Of the performance-based assessments, BESS was most sensitive to SRC at 48 hours post-injury (Cohen’s d=.74, AUC=.70, p<.01). Oculomotor and cognitive testing via ImPACT, WAIS-IV PSI, and TMT-A were sensitive to a lesser degree (Cohen’s d=.35–.58, p<.05). Verbal memory was the only significant performance-based assessment at days 8 and 15, with small-to-medium effect sizes (Cohen’s d=.37 and .44, p<.05). Other cognitive measures (SAC, TMT-B) were not sensitive to SRC across timepoints (p>.05).

Conclusion
We observed heterogeneity in clinical assessment performance such that the clinical domains strongest in the initial days post-injury (symptom severity, balance) were less sensitive at later follow-up, supporting the potential need for multidimensional assessment.
