Non-linear behavioral X-Parameters model of single-phase rectifier in the frequency domain

The increasing use of energy from renewable sources will entail significant changes in power systems. On the generation as well as the load side more and more power electronics devices are in operation, resulting in an increase of harmonics in the power systems. For simulating modern power systems, linear steady-state modeling approaches like single-frequency phasor analysis are not sufficient for accurate simulations or a reliable stability assessment. Different simulation techniques, taking also non-linear components and therefore the generation of harmonics into account, are already known. When the steady-state of a power system is of interest, simulations in the frequency domain are usually more efficient than simulations in the time domain. The X-Parameters behavioral modeling approach for modeling non-linear components entirely in the frequency domain is until now primarily used in microwave engineering. In this paper, this approach is applied for modeling a basic non-linear power electronics device which is common in power systems, a single-phase single diode rectifier.
Balanced feature matching in probabilistic framework and its application on object localisation

A new algorithm of feature matching is proposed after balancing analysis of adjacency matrix of the matching model in a probabilistic framework. Considering all the interaction of the two feature point sets, a probabilistic model is established and solved using random walks with restart RWR. To reduce the influence of deformation, and increase the accuracy of feature matching algorithm, a balancing analysis to the adjacency matrix of RWR is taken. Then an efficient method for bidirectional balance is presented, which makes the relevance weight between each two correspondence candidates balanced. The approach considers not only all the correspondence candidates of the two feature point sets, but also the geometrical relation between each pair of candidates. It improves the discriminative and accuracy performance of matching. Compared with other state-of-the-art algorithms, the method is more robust to outliers and geometric deformation, and is accurate in terms of matching rate in various matching applications, such as object localisation.
Meta Multi-Task Learning for Sequence Modeling

Semantic composition functions have been playing a pivotal role in neural representation learning of text sequences. In spite of their success, most existing models suffer from the underfitting problem: they use the same shared compositional function on all the positions in the sequence, thereby lacking expressive power due to incapacity to capture the richness of compositionality. Besides, the composition functions of different tasks are independent and learned from scratch. In this paper, we propose a new sharing scheme of composition function across multiple tasks. Specifically, we use a shared meta-network to capture the meta-knowledge of semantic composition and generate the parameters of the task-specific semantic composition models. We conduct extensive experiments on two types of tasks, text classification and sequence tagging, which demonstrate the benefits of our approach. Besides, we show that the shared meta-knowledge learned by our proposed model can be regarded as off-the-shelf knowledge and easily transferred to new tasks.
Hepatocellular Carcinoma with Macrovascular Invasion: Defining the Optimal Treatment Strategy

Background: Tumoral macrovascular invasion (MVI) of hepatic and/or portal vein branches is a common phenomenon in hepatocellular carcinoma (HCC) and is associated with poorer prognosis when compared to HCC without MVI. Summary: Current international guidelines for the management of HCC recommend sorafenib as the only treatment option in case of MVI. Despite guideline recommendations, several alternative options have been tested to manage HCC with MVI: surgery, transarterial chemoembolization, external or internal radiation, hepatic arterial infusion chemotherapy, percutaneous treatment, cryotherapy, or the combination of two or more of these strategies, with or without sorafenib. Here we will provide a comprehensive state-of-the-art review for the management of this challenging clinical entity based on the most recent available data. Key Messages: There is a growing body of evidence suggesting that alternative strategies to standard-of-care sorafenib might improve survival in patients with advanced HCC with MVI but the level of evidence remains weak. Randomized phase III trials are ongoing and will hopefully provide information leading towards a more personalized treatment algorithm.
A novel autolysis system controlled by magnesium and its application to poly (3-hydroxypropionate) production in engineered Escherichia coli

ABSTRACT The release of intracellular products, especially polyhydroxyalkanoates, is still a great challenge in industry. To solve this bottleneck, a novel autolysis system strictly controlled with magnesium was constructed and applied to poly(3-hydroxypropionate) production in engineered Escherichia coli. The autolysis system was constructed by inserting the 5′untranslated region (5′UTR) behind promoter PmgtA with lysis genes (S, R, and Rz, from E. coli) overexpressed. The autolysis system functioned well (lysis efficiency of more than 90%) in the P3HP producer with double plasmids containing lysis genes and P3HP biosynthesis genes, whereas the P3HP production was reduced due to plasmid losses. After the autolysis genes and P3HP biosynthesis genes were integrated into one plasmid, the P3HP content of 72.7% (2.4 times of the control) and the plasmid stability of 79.8 ± 3.1% were achieved in strain Q2646 with promoter PmgtA-UTR. However, the strain Q2647 with promoter PmgtA could not accumulate P3HP because of rapid cell lysis. The novel autolysis system activated in Mg2+-depleted conditions proves to be feasible for polyhydroxyalkanoates production, which may have great application potential for other intracellular products.
A statistic related to trees and words on a finite alphabet

Let 𝒯n denote the set of trees on n labeled vertices. In this paper, we consider the statistic on 𝒯n which records the number of vertices of odd degree and count trees having a prescribed number of such vertices. In doing so, we make use of a well-known bijection between members of 𝒯n and the set of n-ary words of length n−2. In fact, we are able to study a generalization mod r of the aforementioned statistic for all r ≥ 2. In the cases when r = 2 and r = 3, further enumerative results for both words and trees may be given.
Prenatal Depression: Screening and Referral for Women Who Are Low Income during Antenatal Care

This study uses prenatal clinical chart reviews of 245 women who were screened for depression while receiving antenatal care services at an urban hospital-based clinic in Syracuse, New York. The results indicate that more than one half of the mothers who screened positive are not being adequately referred and followed-up on to ensure they are receiving proper treatment. Among the mothers who are not being successfully referred are women who are non-English speaking, facing multiple life stressors, and inadequately insured. Recommendations for colocating services that may ease the ongoing burdens of new motherhood are addressed.
Optimized on-line control of MMA polymerization using fast multi-objective DE

ABSTRACT Optimized on-line control (OOC) of polymerization reactors combine the optimization with the on-line operation and control. In this, re-optimized control variable trajectories, in the presence of unplanned disturbances, are obtained and implemented on-line to save the batch. Also, the available computational time for the optimization is limited as the re-optimized trajectories need to be implemented in real time on the actual system. In the present study, the OOC of such a system, i.e., bulk polymerization of methyl methacrylate (MMA) in a batch reactor, is carried out in the occurrence of heater malfunction. To solve the underlying multi-objective problem, a multi-objective variant of differential evolution with an improved mutation strategy is developed. The developed algorithm shows faster convergence with respect to other compared algorithms for a large number of benchmark problems. Finally, this algorithm is used to find the optimal temperature trajectories and the OOC with these trajectories found to be successfully countering the effect of heater malfunction.
Temperature Dependence of the Rayleigh Brillouin Spectrum Linewidth in Air and Nitrogen

The relation between spontaneous Rayleigh Brillouin (SRB) spectrum linewidth, gas temperature, and pressure are analyzed at the temperature range from 220 to 340 K and the pressure range from 0.1 to 1 bar, covering the stratosphere and troposphere relevant for the Earth’s atmosphere and for atmospheric Lidar missions. Based on the analysis, a model retrieving gas temperature from directly measured linewidth is established and the accuracy limitations are estimated. Furthermore, some experimental data of air and nitrogen are used to verify the accuracy of the model. As the results show, the retrieved temperature shows good agreement with the reference temperature, and the absolute difference is less than 3 K, which indicates that this method provides a fruitful tool in satellite retrieval to extract the gaseous properties of atmospheres on-line by directly measuring the SRB spectrum linewidth.
Probing the network structure of health deficits in human aging

Human aging leads to the stochastic accumulation of damage. We model an aging population using a stochastic network model. Individuals are modeled as a network of interacting nodes, representing health attributes. Nodes in the network stochastically damage and repair, with rates dependent on the state of their neighbors. Damaged nodes represent health deficits. The Frailty Index (FI) assesses age-related damage as the proportion of health deficits an individual has accumulated, from a selection of attributes. Here, we use computational, information-theoretic, and mean-field approaches to show that the degree distribution and degree correlations of the underlying network are important to the model’s ability to recover the behavior of observational health data. We use different measures of damage in the network to probe the structure of the network. We find that the behavior of different classes of observational health deficits (laboratory or clinical) is similar to the behavior of nodes of low or high degree in the model, respectively. This explains how damage can propagate within the network, leading towards individual mortality.
Effect of a Phosphodiesterase 5 Inhibitor on Pulmonary and Cerebral Arteries of Newborn Piglets with Chronic Hypoxia-Induced Pulmonary Hypertension

Background: The use of phosphodiesterase 5 (PDE5) inhibitors to treat newborns with pulmonary hypertension is increasing. The effect of PDE5 inhibitors on the neonatal cerebral circulation remains unknown. The neonatal piglet model of chronic hypoxia-induced pulmonary hypertension allows the study of the effects of PDE5 inhibitors on both the pulmonary and cerebral circulations. Objectives: To determine whether the PDE5 inhibitor, zaprinast, causes dilation in pulmonary and middle cerebral arteries (MCA) of normoxic newborn piglets and those with chronic hypoxia-induced pulmonary hypertension, and to evaluate whether zaprinast alters responses to increased pressure (autoregulatory ability) of the MCA. Methods: Two-day-old piglets were raised in normoxia or hypoxia for 3 or 10 days. Pulmonary arteries and MCA were isolated and pressurized, after which changes in diameter to zaprinast were measured. MCA pressure-diameter relationships were determined. Results: Dilation to zaprinast was similar in pulmonary arteries from normoxic and hypoxic piglets. Zaprinast dilated MCA from all groups but the response was diminished in MCA from piglets raised in hypoxia for 10 days. MCA pressure-diameter relationships (autoregulation) did not differ between the groups. Conclusions: Pulmonary artery dilation to zaprinast supports the use of PDE5 inhibitors to treat pulmonary hypertension in neonates. PDE5 inhibitors function as MCA dilators but do not impair the pressure-diameter behavior of the cerebral circulation of either normoxic newborn piglets or those with chronic hypoxia-induced pulmonary hypertension. These findings suggest that cerebral autoregulation is likely to be intact with acute PDE5 inhibitor treatment in infants with pulmonary hypertension in conditions associated with chronic hypoxia.
Computational modeling of epithelial tissues

There is an extensive literature on the computational modeling of epithelial tissues at all levels from subcellular to whole tissue. This review concentrates on behavior at the individual cell to whole tissue level, and particularly on organizational aspects, and provides an indication of where information from other areas, such as the modeling of angiogenesis, is relevant. The skin, and the lining of all of the body cavities (lung, gut, cervix, bladder etc) are epithelial tissues, which in a topological sense are the boundary between inside and outside the body. They are thin sheets of cells (usually of the order of 0.5 mm thick) without extracellular matrix, have a relatively simple structure, and contain few types of cells. They have important barrier, secretory and transport functions, which are essential for the maintenance of life, so homeostasis and wound healing are important aspects of the behavior of epithelial tissues. Carcinomas originate in epithelial tissues.
Registered Replication Report

Finkel, Rusbult, Kumashiro, and Hannon (2002, Study 1) demonstrated a causal link between subjective commitment to a relationship and how people responded to hypothetical betrayals of that relationship. Participants primed to think about their commitment to their partner (high commitment) reacted to the betrayals with reduced exit and neglect responses relative to those primed to think about their independence from their partner (low commitment). The priming manipulation did not affect constructive voice and loyalty responses. Although other studies have demonstrated a correlation between subjective commitment and responses to betrayal, this study provides the only experimental evidence that inducing changes to subjective commitment can causally affect forgiveness responses. This Registered Replication Report (RRR) meta-analytically combines the results of 16 new direct replications of the original study, all of which followed a standardized, vetted, and preregistered protocol. The results showed little effect of the priming manipulation on the forgiveness outcome measures, but it also did not observe an effect of priming on subjective commitment, so the manipulation did not work as it had in the original study. We discuss possible explanations for the discrepancy between the findings from this RRR and the original study.
Association between high-risk fertility behaviours and the likelihood of chronic undernutrition and anaemia among married Bangladeshi women of reproductive age

Abstract Objective To explore the association between high-risk fertility behaviours and the likelihood of chronic undernutrition, anaemia and the coexistence of anaemia and undernutrition among women of reproductive age. Design The 2011 Bangladesh Demographic and Health Survey, conducted from 8 July to 27 December 2011. Setting Selected urban and rural areas of Bangladesh. Subjects A total of 2197 ever-married women living with at least one child younger than 5 years. Exposure was determined from maternal reports of high-risk fertility behaviours. We considered three parameters, maternal age at the time of delivery, birth order and birth interval, to define the high-risk fertility behaviours. Chronic undernutrition, anaemia and the coexistence of anaemia and undernutrition among women were the outcome variables. Results A substantial percentage of women were exposed to have a high-risk fertility pattern (41·8 %); 33·0 % were at single high-risk and 8·8 % were at multiple high-risk. After adjusting for relevant covariates, high-risk fertility behaviours were associated with increased likelihood of chronic undernutrition (adjusted relative risk; 95 % CI: 1·22; 1·03, 1·44), anaemia (1·12; 1·00, 1·25) and the coexistence of anaemia and undernutrition (1·52; 1·17, 1·98). Furthermore, multiple high-risk fertility behaviours appeared to have more profound consequences on the outcome measured. Conclusions Maternal high-risk fertility behaviours are shockingly frequent practices among women in Bangladesh. High-risk fertility behaviours are important predictors of the increased likelihood of women’s chronic undernutrition, anaemia and the coexistence of anaemia and undernutrition.
Effects of high- and low-isoflavone soyfoods on blood lipids, oxidized LDL, homocysteine, and blood pressure in hyperlipidemic men and women.

BACKGROUND Many of the benefits of soy have been attributed to soy isoflavones. OBJECTIVE The objective was to determine the effects of high- and low-isoflavone soy-protein foods on both lipid and nonlipid risk factors for coronary artery disease (CAD). METHODS Forty-one hyperlipidemic men and postmenopausal women participated in a study with three 1-mo diets: a low-fat dairy food control diet and high- (50 g soy protein and 73 mg isoflavones daily) and low- (52 g soy protein and 10 mg isoflavones daily) isoflavone soyfood diets. All 3 diets were very low in saturated fat (< 5% of energy) and cholesterol (< 50 mg/d). Fasting blood samples were drawn and blood pressure was measured at the start and end of each diet. RESULTS No significant differences were seen between the high- and low-isoflavone soy diets. Compared with the control diet, however, both soy diets resulted in significantly lower total cholesterol, estimated CAD risk, and ratios of total to HDL cholesterol, LDL to HDL cholesterol, and apolipoprotein B to A-I. No significant sex differences were observed, except for systolic blood pressure, which in men was significantly lower after the soy diets than after the control diet. On the basis of blood lipid and blood pressure changes, the calculated CAD risk was significantly lower with the soy diets, by 10.1 +/- 2.7%. CONCLUSION Substitution of soyfoods for animal products, regardless of isoflavone concentration, reduces the CAD risk because of both modest reductions in blood lipids and reductions in oxidized LDL, homocysteine, and blood pressure.
Auditory-Motor Control of Vocal Production during Divided Attention: Behavioral and ERP Correlates

When people hear unexpected perturbations in auditory feedback, they produce rapid compensatory adjustments of their vocal behavior. Recent evidence has shown enhanced vocal compensations and cortical event-related potentials (ERPs) in response to attended pitch feedback perturbations, suggesting that this reflex-like behavior is influenced by selective attention. Less is known, however, about auditory-motor integration for voice control during divided attention. The present cross-modal study investigated the behavioral and ERP correlates of auditory feedback control of vocal pitch production during divided attention. During the production of sustained vowels, 32 young adults were instructed to simultaneously attend to both pitch feedback perturbations they heard and flashing red lights they saw. The presentation rate of the visual stimuli was varied to produce a low, intermediate, and high attentional load. The behavioral results showed that the low-load condition elicited significantly smaller vocal compensations for pitch perturbations than the intermediate-load and high-load conditions. As well, the cortical processing of vocal pitch feedback was also modulated as a function of divided attention. When compared to the low-load and intermediate-load conditions, the high-load condition elicited significantly larger N1 responses and smaller P2 responses to pitch perturbations. These findings provide the first neurobehavioral evidence that divided attention can modulate auditory feedback control of vocal pitch production.
Multi-View Structural Local Subspace Tracking

In this paper, we propose a multi-view structural local subspace tracking algorithm based on sparse representation. We approximate the optimal state from three views: (1) the template view; (2) the PCA (principal component analysis) basis view; and (3) the target candidate view. Then we propose a unified objective function to integrate these three view problems together. The proposed model not only exploits the intrinsic relationship among target candidates and their local patches, but also takes advantages of both sparse representation and incremental subspace learning. The optimization problem can be well solved by the customized APG (accelerated proximal gradient) methods together with an iteration manner. Then, we propose an alignment-weighting average method to obtain the optimal state of the target. Furthermore, an occlusion detection strategy is proposed to accurately update the model. Both qualitative and quantitative evaluations demonstrate that our tracker outperforms the state-of-the-art trackers in a wide range of tracking scenarios.
Tight integration of Web APIs with Semantic Web

This short paper describes an initial work to facilitate a better fusion of Web APIs and Linked Data. It explores how the Semantic Web (SW) community can benefit from data available through Web APIs. We believe a tight integration of Web APIs with SW technologies like SPARQL, OWL and reasoning has several advantages over loose integration. We demonstrate how a SPARQL query can be executed against a virtual triple store consisting of virtual triples from (possibly multiple) Web APIs. We discuss the challenges and limitations faced and describe further research on this topic. © 2017 Copyright held by the author/owners.
Co-occurring prescription opioid use problems and posttraumatic stress disorder symptom severity

Abstract Background: Prescription opioids are the most rapidly growing category of abused substances, and result in significant morbidity, mortality and healthcare costs. Co-occurring with psychiatric disorders, persons with prescription opioid problems have negative treatment outcomes. Data are needed on the prevalence of co-occurring prescription opioid abuse and specific disorders, such as posttraumatic stress disorder (PTSD), to better inform clinical practice. Objective: To determine prevalence rates of current co-occurring prescription opioid use problems and PTSD symptom severity among patients in community addiction treatment settings. Methods: We abstracted administrative and chart information on 573 new admissions to three addictive treatment agencies during 2011. Systematic data were collected on PTSD symptoms, substance use, and patient demographics. Results: Prescription opioid use was significantly associated with co-occurring PTSD symptom severity (OR: 1.42, p < 0.05). Use of prescription opioids in combination with sedatives (OR: 3.81, p < 0.01) or cocaine (OR: 2.24, p < 0.001) also were associated with PTSD severity. The odds of having co-occurring PTSD symptoms and prescription opioid use problem were nearly three times greater among females versus males (OR: 2.63, p < 0.001). Younger patients (18–34 years old) also were at higher risk (OR: 1.86, p < 0.01). Conclusions: Prescription opioid use problems are a risk factor for co-occurring PTSD symptom severity. Being female or younger increase the likelihood of this co-morbidity. Further research is needed to confirm these finding, particularly using more rigorous diagnostic procedures. These data suggest that patients with prescription opioid use problems should be carefully evaluated for PTSD symptoms.
