Latar belakang : Proses inflamasi berperan penting dalam patogenesis SLE. Proses inflamasi yang terjadi pada penderita SLE juga akan mempengaruhi diferensiasi osteoklas dan osteoblast. Interleukin-17 (IL-17) merupakan mediator pro-inflamasi yang dihasilkan akibat proses inflamasi sistemik. Peningkatan kadar sitokin pro-inflamasi diketahui mengakibatkan perubahan regulasi RANKL, yang selanjutnya akan mempengaruhi osteoprotegerin (OPG). Peningkatan kadar sitokin pro-inflamasi pada penderita SLE dapat mengakibatkan ketidakseimbangan RANKL/OPG.
Tujuan : Mengetahui korelasi antara kadar IL-17 serum dengan rasio RANKL/OPG pada penderita SLE.
Metode : Penelitian ini merupakan studi observasional analitik potong lintang yang dilakukan di poliklinik dan bangsal rawat inap. Penyakit Dalam RSUP Sanglah Denpasar, Bali, Indonesia dari bulan Januari-Maret 2018. Penderita SLE berjenis kelamin wanita yang berusia lebih dari 18 tahun dan belum mengalami menopause serta bersedia mengikuti penelitian dengan menandatangani informed consent diikutsertakan dalam penelitian. Kadar IL-17 serum diperiksa dengan menggunakan metode high sensitivity ELISA (Enzyme-linked immunosorbent assay). RANKL diukur menggunakan metode Human sRANKL (TOTAL) ELISA, sedangkan OPG diukur menggunakan metode Human Osteoprotegerin ELISA. Rasio RANKL/OPG didapatkan dari perbandingan antara kadar RANKL dan OPG.
Hasil : Penelitian ini melibatkan 68 subyek penelitian. Median umur subyek penelitian yaitu 31,32 (17-54). Kadar IL-17 dan rasio RANKL/OPG pada seluruh subyek yaitu 0,435 (0,23-30,65) dan 70,18 (4,98-1060,46). Didapatkan korelasi yang bermakna antara kadar IL-17 dan rasio RANKL/OPG dengan p=0,010. Dari analisis multivariat didapatkan bahwa kadar IL-17 berkorelasi dengan rasio RANKL/OPG (B=6,554, SE(B)=2,686, p=0,018).
Simpulan : Pada penelitian ini terdapat korelasi antara kadar IL-17 serum dengan rasio RANKL/OPG pada penderita SLE.

Abstract
We show that unsupervised machine learning techniques are a valuable tool for both visualizing and computationally accelerating the estimation of galaxy physical properties from photometric data. As a proof of concept, we use self-organizing maps (SOMs) to visualize a spectral energy distribution (SED) model library in the observed photometry space. The resulting visual maps allow for a better understanding of how the observed data maps to physical properties and allows for better optimization of the model libraries for a given set of observational data. Next, the SOMs are used to estimate the physical parameters of 14,000 z ∼ 1 galaxies in the COSMOS field and are found to be in agreement with those measured with SED fitting. However, the SOM method is able to estimate the full probability distribution functions for each galaxy up to ∼106 times faster than direct model fitting. We conclude by discussing how this acceleration, as well as learning how the galaxy data manifold maps to physical parameter space and visualizing this mapping in lower dimensions, helps overcome other challenges in galaxy formation and evolution.
Compact Object Binary Mergers Driven By Cluster Tides: A New Channel for LIGO/Virgo Gravitational-wave Events
Authors: Hamilton Chris , Rafikov Roman R. 
Published: August 2019

Abstract
The detections of gravitational waves (GWs) produced in mergers of binary black holes (BHs) and neutron stars (NSs) by LIGO/Virgo have stimulated interest in the origin of the progenitor binaries. Dense stellar systems—globular and nuclear star clusters—are natural sites of compact object binary formation and evolution toward merger. Here we explore a new channel for the production of binary mergers in clusters, in which the tidal field of the cluster secularly drives the binary to high eccentricity (even in the absence of a central massive BH) until GW emission becomes important. We employ the recently developed secular theory of cluster tide-driven binary evolution to compute present day merger rates for BH–BH, NS–BH, and NS–NS binaries, varying cluster potential and central concentration of the binary population (but ignoring cluster evolution and stellar flybys for now). Unlike other mechanisms, this new dynamical channel can produce a significant number of mergers out to cluster-centric distances of several parsecs. For NS–NS binaries we find merger rates in the range of 0.01–0.07 Gpc−3 yr−1 from globular clusters and 0.1–0.2 Gpc−3 yr−1 from cusped nuclear clusters. For NS–BH and BH–BH binaries we find small merger rates from globular clusters, but a rate of 0.1–0.2 Gpc−3 yr−1 from cusped nuclear clusters, contributing to the observed LIGO/Virgo rate at the level of several percent. Therefore, cluster tide-driven mergers constitute a new channel that can be further explored with current and future GW detectors.
Linear Independence of Logarithms of Cyclotomic Numbers and a Conjecture of Livingston
Authors: Chatterjee Tapas , Dhillon Sonika 
Published: August 2019

AbstractIn 1965, A. Livingston conjectured the $\overline{\mathbb{Q}}$-linear independence of logarithms of values of the sine function at rational arguments. In 2016, S. Pathak disproved the conjecture. In this article, we give a new proof of Livingston’s conjecture using some fundamental trigonometric identities. Moreover, we show that a stronger version of her theorem is true. In fact, we modify this conjecture by introducing a co-primality condition, and in that case we provide the necessary and sufficient conditions for the conjecture to be true. Finally, we identify a maximal linearly independent subset of the numbers considered in Livingston’s conjecture.
Using GRACE in a streamflow recession to determine drainable water storage in the Mississippi River basin

Published: August 2019

Abstract. The study of the relationship between water storage and
runoff generation has long been a focus of the hydrological sciences. NASA's
Gravity Recovery and Climate Experiment (GRACE) mission provides monthly
depth-integrated information on terrestrial water storage anomalies derived
from time-variable gravity observations. As the first basin-scale storage
measurement technique, these data offer potentially novel insight into the
storage–discharge relationship. Here, we apply GRACE data in a streamflow
recession analysis with river discharge measurements across several
subdomains of the Mississippi River basin. Nonlinear regression analysis
was used for 12 watersheds to determine that the fraction of baseflow in
streams during non-winter months varies from 52 % to 75 % regionally.
Additionally, the first quantitative estimate of absolute drainable water
storage was estimated. For the 2002–2014 period, the drainable storage in
the Mississippi River basin ranged from 2900±400 to 3600±400 km3.

Borderland Unionism: Latina Activism in Ybor City and Tampa, Florida, 1935–1937
Authors: McNamara Sarah 
Published: August 2019

Abstract
This article examines the intersections of gender, labor, and political organizing in Tampa and Ybor City, Florida from 1935 to 1937. By following the personal and professional evolution of labor leader Luisa Moreno in the US South, this article explores the reciprocal relationship between Latina tobacco workers and Moreno’s approach to labor unionism and political mobilization. While Moreno arrived in Tampa prepared to unite workers across ideological and physical barriers, what she encountered was a borderland, a space where multiple groups asserted ultimate authority over place and people. Although the laws and legislation of the US government applied to those living in the city, their regulation depended on the actions of people who lived in the region and independently competed for influence and power. As a result of ethnic and racial boundaries in the city (not only between Anglos and people of color, but also between Latina/o and African American communities), Moreno adapted her strategy of traditional class-based unionism to the realities of this borderland and adopted a Latina-centric approach to labor organizing that joined international radicalism and grassroots interests to challenge the control of de jure and de facto Jim Crow exclusions.
Transpacific Camptowns: Korean Women, US Army Bases, and Military Prostitution in America
Authors: Doolan Yuri W. 
Published: August 2019

Abstract
Military prostitution has been a staple of US–Korea relations since the 1940s, contained in the so-called camptown communities surrounding US military bases in South Korea. But during the 1970s, as the US military steadily reduced its troop presence in Asia, camptowns were thrown into a chaotic state. Facing tremendous social disorder and economic upheaval, establishments that depended upon GI patronage began sending their madams and sex workers to domestic military sites through brokered marriages with US servicemen. These women arrived in the US South, a region housing the vast majority of America’s military. Consequently, southern bases like Fort Bragg in Fayetteville (NC), Fort Campbell in Clarksville (TN), and Fort Hood in Killeen (TX) saw the proliferation of military prostitution, which took form in illicit massage businesses catering to the sexual needs of local troop populations. By the 1980s, the Korean American sex trade would spread from these southern military towns to elsewhere in the United States. Highlighting the transpacific circuits among camptowns in South Korea and military bases in the United States since 1945, this article develops a portrait of the US South as a transnational militarized terrain, the camptown as a transpacific phenomenon, and Korean immigrant community formation as deeply intertwined with the happenings of US militarism abroad. In doing so, it explains how the proliferation of illicit massage businesses witnessed by southern military communities in the 1970s was a transnational outgrowth of military prostitution encouraged by the US military in South Korea.

Authors: Musallam Eyad , Changet Amanda N 
Published: August 2019

Background: High blood pressure is currently affecting 103 million people in the United States and is a major risk factor for cardiovascular disease, stroke, and heart failure. The American Heart Association (AHA) launched Check. Change. Control. Program (CCC program). The program is an evidence-based hypertension management program that utilizes blood pressure self-monitoring to empower patients/participants to take ownership of their cardiovascular health.Project: Following the Partnership Model for Service Learning, Miami University and The AHA propose implementing the “Serve and Learn How to Check, Change, and Control: A Community-Based Intervention to Improve Blood Pressure Control” to improve the BP of a diverse group of residents in Middletown and Hamilton cities in Ohio.Participants: Fifteen nursing students served as volunteer health mentors. Each nursing student recruited five community members over the age of 18 and checked their blood pressure two times every month for four months. 80 community membered were recruited and joined the project for four months.Results: At the end of the program, more than half of the participants (n = 41) had blood pressure improvement (decrease in systolic or/a diastolic). On third of Tier 1/ HYPERTENSION participants (n = 10) have moved from uncontrolled (> or = to 130/80) to controlled (< or = to 129/79) based on comparing the participants’ 1st blood pressure reading to their last.Conclusions: The extremely positive effects of this project are an eye-opening on the need of applying the program on a larger scale. To apply this program on a larger scale, partnerships with community organizations such as community health and wellness centers are needed. These partnerships will provide quality access to healthcare. The students will be able to meet participants where they are in their communities in a safe, vibrant, open and welcoming centers.
Horse phenotyping based on video image analysis of jumping performance for conservation breeding
Authors: Lewczuk Dorota , Metera-Zarzycka Ewa 
Published: August 2019

Background
Many horse breeds in the world are reserved as genetic resources; however, their characteristics seem to be insufficiently clarified, especially in terms of horse performance. Two jumping ability evaluation methods have been used to compare different types of performance breeds and on this basis their applicability for precision phenotyping has been determined.

Methods
Jumping data of 186 young Polish Warmblood stallions (27 with an endangered status) bred for sport and multipurpose use was collected during their performance tests organised under identical environmental conditions following the same guidelines. Jumping data consisted of objective measurements of free jumping parameters and the marks for jumping. Video recordings of 514 jumps (73 records for 27 stallions with an endangered status) were collected using a digital Panasonic AG-EZ 35 camera (25 fr/sec). Filming was recorded during a free jumping test in the line on a doublebarre obstacle (100–120 cm × 100 cm). Spatial and temporal variables of the jump were measured. The analysis of variance was performed (SAS, General Linear Model and Mixed procedures) using the statistical model, which included the random effect of the horse and fixed effects of the year of test, breeding status, height of jump and the successive number of the jump for objective kinematic data. The fixed effects of the year of test and breeding status were included in the model for subjective performance test data.

Results
Performance marks for free jumping were lower in the endangered group of stallions in the trainers’ opinion (p ≤ 0.05), while no statistically significant differences were found in the judges’ opinions. Statistically significant differences in jumping variables were measured for the bascule points—the elevations of the withers and croup were higher in the endangered group (p ≤ 0.001) and the take-off time was prolonged (p ≤ 0.05), which explained the subjective evaluation.

Discussion
The use of objective evaluation methods provides important information for practice, as phenotypic differences between horses may be unclear in the subjective evaluation. The objective evaluation should be used to characterise the performance potential of different breeds, because the information from the evaluators might not be consistent. Such characteristics should be recorded at least for every new population.

Published: August 2019

Background/Objective: Vegetables and fruits play a highly significant role in food security of the underprivileged in both urban and rural settings. The study was designed to determine the nutritional composition of some neglected underutilized fruits and vegetables in Southeast geopolitical zone of Nigeria.
Methodology: The commonly occuring underutilized fruits and vegetables were selected for the study. The food crops were harvested and identified at the Herbarium in the Department of Plant Science and Biotechnology, University of Nigeria Nsukka. Twenty underutilized fruits and vegetables each were cleaned and analysed for nutrients composition using standard methods. Data were presented using descriptive statistics, percentage, mean, standard deviation and frequency.
Results: The proximate composition of the fruits ranged from 54.34-80.30% moisture, 0.27-6.21% protein, 0-3.08% fat, 0.28-8.58 % fibre, 0.33-11.05% ash and 9.08-36.61% carbohydrate. The ranges for mineral values of the fruits were iron 0.10-9.60 mg, zinc 0.02-10.30 mg, manganese 0.10-6.60 mg and calcium 5.42-46.50 mg. The vitamin contents of the fruits ranged from beta-carotene traces -5666.67 RE, ascorbic acid 0-48.82 mg and vitamin E 0 -11.99 mg. The proximate composition of the vegetables ranged from moisture 60.45-91.00%, protein 0.02-6.60%, fat 0.02-2.19%, fibre 0.04-5.01%, ash 0.04-4.20% and carbohydrate 10.30-36.61%. The ranges for mineral values of the vegetables were iron 1.40-14.80 mg, zinc trace-9.40 mg, manganese 0.07-4.80 mg and calcium 18.19-400.00 mg. The vitamin levels of the vegetables were beta-carotene 15.20-1933.33 RE, ascorbic acid 2.40-38.40 mg and vitamin E traces - 6.67 mg.
Conclusion: The use of these fruits and vegetables should be encouraged particularly in areas where they are not produced through nutrition education in order to promote the food use of these crops.

Published: August 2019

This paper reports findings from a study carried out to investigate the profitability of snail marketing in Ibadan North East Local Government area of Oyo State. Structured questionnaires and interview schedules were designed to obtain information on socio-economic characteristics, operational capital and source, years of experience in the business and constraints to snail marketing. Seventy snail marketers, randomly selected from three major markets which are Oje, Agodi gate and Agugu market;. The data collected were analyzed using frequency table, percentage, gross margin, Benefit/ Cost ratio and Marketing Efficiency analyses. Majority (94.3%) of the respondents were female while 5.7% were male. 31.5% were between the ages of 51-60years with mean age of 54.9 years. It was also shown that 50% source their capital through personal savings between N11,000-N20,000 and 47.1% with 5-9years experience. The cost and return analysis revealed that total revenue was N1, 457,700.00k and total cost was N1, 285,320.00k while gross margin was N172, 380.00k and benefit- cost ratio was 1.13 which implies that for every N1.00 invested the marketer will make a return of N1.13k on every snail sold, Marketing efficiency was 88%. Major constraints to snail marketing in the study area were poor market patronage (87.1%) and seasonality (82.9%). Snail farming is advocated since it is a profitable agribusiness and can be achieved through cooperatives and micro credit facilities. Also, marketing of snail in the area should be restructured and standardized to command frequent patronage and command higher price value.

Published: August 2019

ObjectiveTo externally validate the European League Against Rheumatism/American College of Rheumatism (EULAR/ACR) classification criteria for idiopathic inflammatory myositis (IIM) and determine the optimal cut points for Australian patients. To determine the level of agreement with traditional criteria and assess the effect of including magnetic resonance imaging (MRI) and an extended myositis antibody panel as well as extending histological criteria to include myofiber invasion.MethodsData were collected on adult patients referred for muscle biopsy to two Australian teaching hospitals. Patients were scored for “risk of IIM” according to EULAR/ACR criteria, using clinician diagnosis as the gold standard.ResultsOverall, 87 of 204 patients had IIM. For patients with muscle biopsy, the optimal cut point of 5.25 (sensitivity 90%, specificity 89%) was lower than the EULAR/ACR cut point of 6.7, which in our cohort showed reduced sensitivity (71% vs 93%) but comparable specificity (89% vs 88%). We found moderate agreement between the EULAR/ACR criteria and Bohan and Peter (κ = 0.45, 95% confidence interval [CI] = 0.28, 0.62, P < 0.001) and Targoff (κ = 0.40, 95% CI = 0.23, 0.57, P < 0.001). Inclusion of MRI (area under curve [AUC] = 0.86, 95% CI = 0.79, 0.93) or non‐Jo1 antibodies (AUC = 0.84, 95% CI = 0.77, 0.91) as covariates improved the probability of IIM diagnosis (AUC = 0.80, 95% CI = 0.75, 0.86). Extending histologic criteria to include myofiber invasion slightly improved sensitivity (75% vs 71%) with the same level of specificity (89% vs 89%).ConclusionApplication of the EULAR/ACR criteria to an Australian cohort showed comparable specificity but lower sensitivity, and a lower optimal cut point. Inclusion of MRI or non‐Jo1 antibodies as covariates may improve the accuracy of determining the probability of IIM diagnoses. Extending the histologic criteria to include myofiber invasion did not reduce specificity.
Constructing Conductive Interfaces between Nickel Oxide Nanocrystals and Polymer Carbon Nitride for Efficient Electrocatalytic Oxygen Evolution Reaction

AbstractCombining transition metal oxide catalysts with conductive carbonaceous material is a feasible way to improve the conductivity. However, the electrocatalytic performance is usually not distinctly improved because the interfacial resistance between metal oxides and carbon is still large and thereby hinders the charge transport in catalysis. Herein, the conductive interface between poorly conductive NiO nanoparticles and semi‐conductive carbon nitride (CN) is constructed. The NiO/CN exhibits much‐enhanced oxygen evolution reaction (OER) performance than corresponding NiO and CN in electrolytes of KOH solution and phosphate buffer saline, which is also remarkably superior over NiO/C, commercial RuO2, and mostly reported NiO‐based catalysts. X‐ray photoelectron spectroscopy and extended X‐ray absorption fine structure spectrum reveal that a metallic Ni–N bond is formed between NiO and CN. Density functional theory calculations suggest that NiO and CN linked by a Ni–N bond possess a low Gibbs energy for OER intermediate adsorptions, which not only improves the transfer of charge but also promotes the transmission of mass in OER. The metal–nitrogen bonded conductive and highly active interface pervasively exists between CN and other transition metal oxides including Co3O4, CuO, and Fe2O3, making it promising as an inexpensive catalyst for efficient water splitting.
