Constrained Control of Low-Capacitance Delta Cascaded H-Bridge StatComs: A Model Predictive Control Approach

This article presents a constrained model predictive control (MPC) strategy for a three-phase low-capacitance static compensator (LC-StatCom) with delta configuration. The controller consists of an outer loop that provides dynamic references for the active grid current component and the circulating current; whereas, the inner predictive loop minimizes the quadratic error of state variables subject to operating limit conditions, thus providing optimal control signals that produce a fast response while guaranteeing the prescribed safe operating limit conditions. The article also proposes an enhanced discrete-time model, which uses intersample values, that improves the accuracy of the model predictions when the sampling rate is not high enough to assume constant state variables. As a result, it facilitates the implementation of MPC on less powerful processors compared to the conventional modeling. The proposed control is especially suited for the LC-StatComs since it incorporates analytical computation of desired steady-state trajectories, which takes into account the induced oscillation on the capacitor voltages that are inherent to the LC-StatComs. The proposed approach has been verified by simulation and experimentally with a laboratory prototype.
Quasiperiodic Emissions and Related Particle Precipitation Bursts Observed by the DEMETER Spacecraft

Electromagnetic waves observed in the inner magnetosphere at frequencies between about 0.5 and 4 kHz sometimes exhibit a quasiperiodic (QP) time modulation of the wave intensity with modulation periods from tens of seconds up to a few minutes. Such waves are typically termed “QP emissions” and their origin is still not fully understood. We use a large set of more than 2,000 of these events identified in the low‐altitude DEMETER spacecraft data to check for energetic electron flux variations matching the individual QP wave elements. Altogether, seven such events are identified and their detailed analysis is performed. Energetic electron fluxes are found to be modulated primarily at energies lower than about 250 keV. While the waves may propagate unducted across L‐shells, the energetic particles follow magnetic field lines from the interaction region down to the observation point. This is used to estimate the locations of anticipated generation regions to L‐shells between about 4 and 6, and the respective source radial dimensions to about 0.6–1.2 Earth radii. The frequencies of the events are confined below half of the equatorial electron gyrofrequency in the determined source regions. Finally, it is shown that individual QP elements exhibit a fine inner structure corresponding to the wave bouncing between the hemispheres.
Beneficiary perspectives toward medical health camps in the Himalayan Regions: A new education strategy for medical undergraduates

Backgrounds: National Health Mission emphasizes the delivery of health-care services to the doorstep of the population. The geographical terrain of villages in the Himalayan region necessitates medical health camps’ needs to deliver affordable and accessible healthcare to the people. Aim and Objective: The aim of the study was to explore the profile of camp beneficiaries and determines their perception and satisfaction toward medical health camps conducted in the Himalayan regions. Materials and Methods: The study was employed in remote villages, Uttarakhand, India. A self-structured and pre-tested questionnaire were used to collect information on the profile, satisfaction, and camp beneficiaries’ perception. Data are presented using descriptive statistics, frequency, and percentages. Results: 3200 population attended camps, 478 patients consented to participate in the survey (14.93%). The average distance traveled by the patients to attend camps was (2.32 ± 1.10) km. The mean distance of the nearest health-care facility was located at 17.05 ± 5.90 km. About 67.57% population was satisfied with health camps services in areas. Overall, minor medical ailments were common (37%), followed by musculoskeletal (16%) and skin (12%). Further, 78.87% of the population would like to attend medical camps in the future and become more health-conscious after attending health camps (81.38%). About 99.73% of the patients expressed a need for the availability of drugs in the camps. Conclusions: Health camp beneficiaries appreciated the event and expressed the need to organize such camps in the future. Organizing camp is a novel approach to deliver essential health-care services at the doorstep in remote areas. It can be used as a new tactic to teach medical undergraduates.
Capital Structure and Trade-Off Theory: Evidence from Vietnam

The capital structure is one of the hot financial topics among researchers and scholars. Its importance comes from the fact that capital structure is closely related to companies’ ability to meet different stakeholders’ needs. A suitable capital structure will boost the business and create a competitive advantage in the context of fierce competition. Many companies choose an optimal debt level based on the trade-off between interest and debt costs. This study aimed to test the existence of trade-off theory in capital structure, the case of Vietnam’s real estate companies, which are growing very fast recently. Instead of considering constant optimal leverage to test the trade-off model, we take advantage of the dynamic capital structure determined by growth opportunities, profitability, tax incentives, tangibility, liquidity, and firm size. The dynamic panel data regression was estimated by the system Generalized Method of Moment (Sys-GMM). The empirical evidence showed that real estate companies listed in the Vietnamese stock market might change their leverage toward a target capital structure determined by influential factors in a long-term perspective. In particular, the debt-to-asset ratio will change by approximately 14 percent, positively, in response to the difference between the current debt-to-asset ratio and the dynamic target debt-to-asset ratio.

Frequency of different indications for endodontic treatment among patients from Pancevo, Serbia

Introduction: Different types of irreversible pulp diseases are the most commonly stated reasons for conducting root canal treatment. Data obtained from epidemiological studies are of great importance for a better understanding of endodontic pathology and for evaluating the need for this kind of treatment. Aim: The aim of this epidemiological study was to evaluate the structure of endodontic pathology among selected adult population of municipality of Pancevo, Serbia, indicated for endodontic treatment. Material and methods: Investigations were conducted on a sample of patients who referred for dental examination and treatment, at the Department of Restorative Dentistry and Endodontics, Faculty of Dentistry in Pancevo, during 2018. The study included 229 male and female subjects, aged over 18, who had at least one tooth indicated for endodontic treatment. Subjects were clinically examined by a standardized procedure, using visual and tactile inspection, percussion and palpation tests, periodontal evaluation and pulp vitality tests. Panoramic and retroalveolar radiographs were also analyzed. Data were statistically analyzed using Chi-Square test. Results: Endodontic treatment was indicated on 322 teeth from total number of 4911 (6.6%). Largest frequency of teeth indicated for treatment was recorded among subjects aged over 60 years (7.5%) and on frontal teeth (36.6%). The most commonly registered indications were asymptomatic irreversible pulpitis (32.3%) and symptomatic irreversible pulpitis (19.9%). Irreversible pulpitis was the most common indication for endodontic treatment between all age groups of subjects, between both genders and between all three teeth functional groups (p < 0.001). Conclusion: Percentage of teeth indicated for endodontic treatment was higher than presented in other studies. Irreversible pulpitis was the most common indication for endodontic treatment. After conducting the study, it is clear that dental care and caries preventive programs should be strengthened and expanded, especially among people with less education and awareness regarding dental health.
Evaluation of Growth, Yield and Quality of Turmeric Genotypes (Curcuma longa L.)

This study was conducted to find out growth, yield and quality performances of five turmeric genotypes. The experiment was laid out in randomized complete block design with three replications. Results showed that different genotypes significantly influenced on plant growth, yield and quality of turmeric. The highest germination (97 %), number of leaves (8.16), plant height (69.51 cm), weight of rhizome (47.06 g/plant) and yield (6.01 t/ha) was found from “Sinduri Holud” (BARI Holud-2). But this genotype scored the lowest percentage in curcumin (0.30 %) and low dry matter (22.54 %). While local genotype (“Mota Holud”) performed the lowest germination (87.57 %) and minimum plant height (53.52 cm), leaf area (127.42 cm2), number of fingers per rhizome (3.73), weight of rhizome (34.16 g/plant) and yield (4.78 t/ha). But this genotype contained the highest curcumin (2.10 %), and “Mala Holud” attained maximum dry matter (25.20%). Based on flesh color, dry matter and curcumin contents local turmeric genotypes performed superior than that of the check varieties. From the findings of this investigation, it can be concluded that local genotypes can be used in breeding program for development of high quality turmeric in Bangladesh.
Adaptive Polygon Generation Algorithm for Automatic Building Extraction

Buildings serve as the main places of human activities, and it is essential to automatically extract each building instance for a wide range of applications. Recently, automatic building segmentation approaches have made great progress in both detection and segmentation accuracy due to the rapid development of deep learning. However, these approaches struggle to delineate regular and accurate building boundaries due to the limitations in inferring overall structure of the building instance; this might lead to inconsistency in building geometry and difficulty in being applied directly to practical engineering. To tackle this challenge, this article presents an adaptive polygon generation algorithm (APGA), a novel method that aims at directly generating a polygonal output, parameterized as a sequence of building vertices, to outline each building instance. To achieve this, APGA predicts the candidate locations of building vertices and determines the arrangement of these vertices with the help of the position and orientation of the building boundary. Moreover, to introduce local context features and achieve improved performance of the predicted building polygon, APGA integrates finer structures around the candidate vertices to refine their positions. Experiments on several challenging building extraction datasets demonstrated that APGA outperformed state-of-the-art methods in terms of building coverage and geometric similarity.
How well can screening sensitivity and sojourn time be estimated

Chronic disease progression models are governed by two main parameters: preclinical intensity and sojourn time. The estimation of these parameters helps in optimizing screening programs (with an additional parameter: sensitivity of the screens), and we examine their effect in improving survival. Multiple approaches exist for estimating these parameters. However, these models are based on strong underlying assumptions. Our main aim is to investigate the effect of these assumptions. For this purpose, we developed a simulator to mimic a breast cancer screening program while directly observing the exact onset and the sojourn time of the disease. We then examine the performance of the model under different parameterizations and investigate the effects of different models on the sensitivity, the inter-screening intervals and misspecification of the used parametric distributions. Our results indicate a strong correlation among the estimated parameters. Besides, the underlying assumptions have a strong effect on the overall performance of the model. These findings shed a light on the seemingly discrepant results obtained by different authors using the same data sets but different assumptions.
High sensitivity chlorogenic acid detection based on multiple layer-by-layer self-assembly films of chitosan and multi-walled carbon nanotubes on a glassy carbon electrode

A chlorogenic acid sensor based on a chitosan (CS) and multi-walled carbon nanotubes (MWCNTs) modified glassy carbon electrode (GCE) was fabricated via a layer-by-layer (LBL) self-assembly method. The prepared electrode exhibited excellent catalytic performance for chlorogenic redox reactions compared to the bare GCE. The effects of the number assembly layers, scan rate, pH of the supporting electrolyte and accumulation time on chlorogenic acid detection were optimized. Under the optimal conditions, the proposed sensor was significantly sensitive for the detection of chlorogenic acid and showed wide linear detection ranges at low concentrations from 2 × 10−8 to 1 × 10−7 mol dm−3 and at high concentrations from 1 × 10−7 to 2.25 × 10−4 mol dm−3. The detection limit was estimated to be 1.16 × 10−8 mol dm−3 (S/N = 3). Furthermore, the chlorogenic acid sensor exhibited excellent selectivity and stability and was utilized in practical applications, in particular, for the determination of human real samples.
New Normal in Nursing Education: Sophomore Students’ Expectations of and Readiness for Online Learning in the Era of COVID-19 Pandemic

Background: The global disruption of the COVID-19 outbreak in education has resulted in a new normal in how education is delivered. Traditional face-to-face nursing education has suddenly transitioned into a remote and online learning environment to help mitigate virus transmission. Students’ anticipations and how set they are in this new learning platform should be investigated. Objective: This study determined the expectations of and readiness for online learning of sophomore nursing students in one nursing school in a developing country. Methods: This study employed a cross-sectional research design. The Student Expectations of Online Learning Survey (SEOLS) and Online Learning Readiness Scale (OLRS) were the instruments used to gather data administered online. Descriptive statistics and non-parametric statistical tests were used in the data analysis. Results: Nursing students had high proficiency with technology but more than one-fourth had an unstable Internet connection. Nursing students generally had high expectations of and readiness for online learning. Although high, expectations about social interactions in the online learning environment obtained the lowest mean score among the five subscales of the SEOLS. Readiness for online learning significantly differed based on family income status and Internet stability. Bivariate analysis indicated a significant positive correlation between students’ expectations and readiness for online learning. Conclusions: Students’ expectations may play a role in students’ readiness for online learning. This study suggests that while students appear ready to take on online learning, the different students’ circumstances along with the challenges associated with online learning such as limited internet connectivity must be properly addressed. It may be necessary for nursing schools to meet students’ expectations in the new learning environment to fully maximize learning and facilitate success and learner readiness in the new normal in nursing education.
The Impact of Exchange Rate, Bank Indonesia Certificate and Global Indexes on the Composite Price Index (IHSG) in Indonesia

The purpose of this study is to analyze the contribution of exchange rates, Bank Indonesia Certificate (SBI), and global stock price indexes toward the Composite Stock Price Index (IHSG), and the shocks caused by the global index to the IHSG. The research variables are HSGI, rupiah exchange rate, and global stock price index, which includes NASDAQ, the Hong Kong stock price index (Hang Seng), the Japanese stock price index (Nikkei 225), and the South Korean stock price index (Kospi). The data used is monthly time-series data from 2008 to 2019. The data used in this study are secondary data obtained from Bank Indonesia publications through www.bi. go.id, the Indonesia Stock Exchange, and Yahoo Finance (finance.yahoo.com). Following the type of data used, the research steps include the unit root test, cointegration test, and estimation using the Vector Error Correction Model (VECM). Based on the results of the impulse response and variance decomposition analysis, it can be seen that the overall global index, exchange rates, and SBI interest rates contributed to the IHSG movement. Based on the analysis of variance decomposition, the percentage value of the contribution of the Hang Seng index is the biggest compared to the NASDAQ, Nikkei 225, and Kospi.
Profiling native and introduced perennial garden plants in Puerto Rican urban residential yards

Worldwide the number of non-native species escaping from cultivation into native habitats is steadily increasing with no signs of saturation. Species that eventually become invasive may generate unwanted social and ecological conditions especially in areas of conservation concern. This study built upon prior biodiversity work from 432 residential yards in the San Juan Metropolitan Area of Puerto Rico to evaluate the natural history and functional traits of native and non-native plant species in these green spaces. We reviewed the literature for a total of 361 plant species to extract information on their taxonomy, native distribution range, invasive status (casual, naturalized or invasive), life-form and ecological and biological species attributes. We then evaluated the relationship between their attributes and their probability of escaping cultivation and become invasive. Our results show that non-native species growing in yards are more likely to succeed in becoming invasive if they have vegetative growth, a mixed breeding system, and an unspecialized dispersal mode. We also found that native and non-native species occurring in residential yards share similar adaptive strategy scores. Most plant species that have already become invasive originated from Asia and America a fact that is likely tied to the US nursery trade. We used the combined results of this and prior studies to understand the factors facilitating plant invasion and to generate recommendations for the development of management strategies that may limit the spread of non-native ornamentals with the potential to escape cultivation and become invasive on this island.
A novel strategy to improve the dyeing properties in laccase‐mediated coloration of wool fabric

Enzymatic coloration of fabrics has received worldwide attention in recent years. In order to improve the dyeing properties of enzymatically coloured fabrics, a novel strategy using 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (EDC), a biological coupling agent, to pretreat wool fabric was employed in this paper. Enzymatic coloration of wool fabrics with syringic acid was carried out in the presence of laccase from Trametes versicolor. The effect of different periods on laccase-catalysed polymerisation of syringic acid was examined by UV-vis spectroscopy. Enzymatic coloration results of dyed wool fabrics were evaluated by means of K/S value and colour difference (∆E*). Process parameters, including the dosages of syringic acid and incubation time, that influenced the colour depth were studied. Meanwhile, the colour fastness and levelness of dyed wool fabrics were tested. The results showed that the UV-vis absorbance of reaction solution increased as oxidation time elapsed, and a new peak appeared at 360 nm. After pretreatment, the K/S values and colour difference values of wool fabrics dyed with poly(syringic acid) improved appreciably compared with the control samples without any pretreatment. Moreover, pretreated wool fabrics showed better dyeing fastness and levelness than control samples.
