Abstract Coal is the main energy source in China. At present, the coal overcapacity is still serious in China. Accurately measuring the degree of China’s coal overcapacity can scientifically resolve the overcapacity, and is the premise of guiding the healthy development of coal industry and energy system. Using the translog cost function and the panel data of coal industry in all provinces of China from 2002 to 2011 and from 2012 to 2016, the research measures and compares the coal production capacity of “golden decade” and “cold winter” in China. The results show that: (1) The More >

Abstract Introduction: Health care‐associated infections (HAIs) increase mortality, length of stay, and cost in hospitalized patients. The incidence of and risk factors for developing HAIs in the pediatric population after cardiac surgery have been studied. This study evaluates the impact of HAIs on length of stay, inpatient mortality, and cost of hospitalization in the pediatric population after cardiac surgery.
Methods: TheKids’InpatientDatabasewasqueriedforanalysis.Patientsunder18years of age who underwent cardiac surgery from 1997 to 2012 were included. HAIs were defined as central line‐associated blood stream infections, catheter‐associated urinary tract infections, ventilator‐associated pneumonias, and surgical wound infections. Univariate analysis compared admissions with and… More >

Abstract Objective: Maternal anti-Ro/SSA and anti-La/SSB antibodies can lead to fetal complete heart block (CHB). Current guidelines recommend weekly echocardiographic screening between 16 and 28 weeks gestation. Given the cost of screening and the rarity of conduction abnormalities in fetuses of mothers with low anti-Ro levels (<50 U/mL), we sought to identify a strategy that optimizes resource utilization.
Design: Decision analysis cost-utility modeling was performed for three screening paradigms: “standard screening” (SS) in which mid-gestation mothers are screened weekly, “limited screening” (LS) in which fetal echocardiograms are avoided unless the fetus develops bradycardia, and “targeted screening by maternal… More >

Abstract Cyber-physical system (CPS) is an advanced system that integrats physical processes, computation and communication resources. The security of cyber-physical systems has become an active research area in recent years. In this paper, we focus on defensive strategies against network attacks in CPS. We introduce both low- and highinteraction honeypots into CPS as a security management tool deliberately designed to be probed, attacked and compromised. In addition, an analysis resource constraint is introduced for the purpose of optimizing defensive strategies against network attacks in CPS. We study the offensive and defensive interactions of CPS and model… More >

Abstract Although pre-Northridge earthquake steel moment resisting frame buildings have been shown to be susceptible to brittle connection failures, they still represent a large fraction of the existing steel buildings in the United States of America. In this study, the performance of the 3- and 9-story Los Angeles pre-Northridge SAC buildings are analyzed considering ductile and brittle beam-column connection failures, and their uncertainty. This paper contributes to understanding the influence of uncertainty associated with connections brittle fracture on building interstory deformation capacity and its impact on bias and variability of fragility functions and loss assessment.

Abstract Recently, many researchers have concentrated on distant supervision relation extraction (DSRE). DSRE has solved the problem of the lack of data for supervised learning, however, the data automatically labeled by DSRE has a serious problem, which is class imbalance. The data from the majority class obviously dominates the dataset, in this case, most neural network classifiers will have a strong bias towards the majority class, so they cannot correctly classify the minority class. Studies have shown that the degree of separability between classes greatly determines the performance of imbalanced data. Therefore, in this paper we More >

Abstract The Sarbanes-Oxley (SOX) Act 2002 resulted from the mounting accounting and corporate scandals in the late 1990s and early 2000s. Since the passage of the SOX Act, companies are facing even greater challenges to meet raised expectations to provide accurate, visible, and timely information for SOX compliance. This research puts forth a systems design framework to achieve a real time, accurate, consistently traceable and easily verifiable SOX compliant technology. Our multidisciplinary and integrative systems design incorporates Overall Equipment Effectiveness (OEE) to ensure effective business performance within a knowledge represented company modeled as Enveloped Activity Based More >

Abstract In the 2017, “Cairo Accord on Rheumatic Heart Disease—From Molecules to The Global Community” experts from endemic areas enumerated an approach to reduce the population burden of rheumatic heart disease. The 10 key recommendations in‐ clude immediate logistical objectives as well as domains for further study. Echocardiographic population screening programs were relegated to research alone. Given the large body of supporting data, relegating echo screening to an investiga‐ tional modality is an opportunity lost. More >

Abstract An alternative method for improving the production of habanero chili is the tissue culture technique; however, the gelling agent, the high salt and sucrose concentrations used in the culture media raise production costs and limit the adaptation of the regenerated plants to greenhouse or field conditions. In this study, the effect of the substrates perlite-coconut fiber, coconut fiber-volcanic rock, vermiculite-perlite, and perlite-volcanic rock in conjunction with various culture media in in vitro plant regeneration from embryos was evaluated. The differentiation of adventitious shoots on substrates was scarcely observed or non-existent. Inducing the formation of shoots on… More >

Abstract Background: Standardized Clinical Assessment and Management Plans (SCAMPs) are a quality improvement initiative designed to reduce unnecessary utilization, decrease practice variation, and improve patient outcomes. We created a novel methodology, the SCAMP managed episode of care (SMEOC), which encompasses multiple encounters to assess the impact of the arterial switch operation (ASO) SCAMP on total costs.
Methods: All ASO SCAMP patients (dates March 2009 to July 2015) were compared to a control group of ASO patients (January 2001 to February 2009). Patients were divided into “younger” (<2 years) and “older” (2–18 years) subgroups. Utilization included all cardiology visits,… More >
