Polynomial Estimation of Flux Linkage for Predictive Current Control in PMSM

This article presents an automatic parameter identification method based on ordinary least square (OLS) algorithm for deadbeat predictive current control (DPCC) to fulfill the purpose of high steady and dynamic performance in permanent magnet synchronous motor (PMSM) drives. Different from the conventional model, a novel model based on the polynomial estimation of flux linkage is constructed which takes the cross-saturation effects into account. First, the conventional mathematical model of PMSM and the proposed model are presented, respectively, and the inverter considering nonideal factors is also analyzed. Then the parameter identification method is investigated, in which the measurement procedure is delimited in advance and the automatic identification method is developed. Furthermore, a voltage reconstruction algorithm is applied to solve the inverter nonlinearities and the digital time-delay effect, so as to improve the accuracy of the identified parameters. Accordingly, a novel DPCC algorithm is presented based on the proposed model to achieve better performance. Finally, based on the concept and principles mentioned before, a detailed comparison of the DPCC based on the classical model considering the parameters’ variation and the modified model of the proposed method is carried out on a laboratory prototype.

This study aims to obtain WTP of Faculty of Economics’s students for reducing property crime and non-property crime on campus and to explore campus security from 300 student samples through purposive proportional sampling in Universitas Negeri Yogyakarta (UNY) campus. Utilizing Contingent Valuation Method, this research is carried out to obtain the ability to pay the respondents. The econometric approach and descriptive statistical analysis is carried out to achieve the purpose. On the average, the student’s WTP is Rp106,400 where the students of the P.ADP study program has the largest one. Various factors that influence the level of WTP are family income and education level of the head of the family, the status of victims and criminals if carried out by employees, physical damage, and the level of obedience when the costs of crime become tax and concrete actions to anticipate crime. This means that students have a high commitment to provide the fund for reducing the crime in UNY campus.
Inflammation-Related Gene Signature for Predicting the Prognosis of Head and Neck Squamous Cell Carcinoma

Purpose The inflammatory response was associated with the prognosis of head and neck squamous cell carcinoma (HNSCC). This study aimed to perform a novel prognostic signature based on inflammation-related genes (IRGs) for a better understanding of the prognosis of HNSCC. Patients and Methods IRGs were obtained from The Cancer Genome Atlas (TCGA) database and the Gene Expression Omnibus (GEO) database. Functional enrichment analysis was performed to explore potential pathways. Univariate and multivariate Cox regression as well as the Least Absolute Shrinkage and Selection Operator (LASSO) were utilized to construct an IRGs-based prognostic model on TCGA database and the GEO database was utilized for outcome validation. The nomogram model was constructed based on independent prognostic factors after univariate and multivariate Cox regression. The immune cell infiltration level was analyzed via the Tumor Immune Estimation Resource (TIMER) database. Results In this study, we confirmed that 60% IRGs were abnormally expressed in HNSCC samples, and these were associated with important oncobiology. Then, a prognostic signature comprising 7 hub genes was generated based on TCGA database. The results were validated in 97 patients from GSE41613. A nomogram comprising risk score, age, M stage and N stage was generated to improve the accuracy of prognosis evaluation. The immune cell infiltration analysis suggested that 5 hub genes (ADGRE1, OLR1, TIMP1, GPR132 and CCR7) were negatively correlated with tumor purity and positively correlated with the infiltration of immune cells. Conclusion Our study established a novel signature consisting of 7 hub genes for the prognostic prediction in patients with HNSCC.
Evaluation of Plant Growth Parameters by In vitro and Ex vitro Inoculation of Micropropagated Banana Plantlets with Rhizospheric and Endophytic Bacterial Inoculum

Banana propagation is dependent on propagation by tissue culture for industrial purposes. Due to lack of native endophytes in tissue culture plantlets, reintroduction of beneficial microorganisms to tissue culture plantlets become popular as a useful foundation for improving the level of establishment, increasing plant growth parameters, protecting the plantlets against pest and diseases and overall performance for field plantation. In the present study, rhizospheric and endophytic four bacterial species (Pseudomonas fluorescens, Bacillus putida, Bacillus pumilus, Bacillus amyloliquefaciens were isolated from different parts of healthy banana plants such as root, leaf and pseudostem. Banana tissue culture plantlets were cultured for root formation stage on MS medium and used as host for artificial inoculation. Then, bacterial inoculation was carried out with tissue culture plantlets both in vitro and ex vitro conditions. All banana plantlets used for this experiment were successfully acclimatized and survived in the greenhouse. The experiment consisted of three treatments: (1) bacterial inoculum with in vitro rooted plantlets for 2 weeks (2) bacterial inoculum with ex vitro (hardening) plantlets (3) control with sterilized distilled water. Among these treatments, in vitro inoculation affected significantly increased plant height, number of leaves and plant girth for all data collection times with the highest increment indices: (24.0, 7.0, and 7.3). Ex vitro inoculation showed the second highest increment indices: (22.0, 6.9 and 6.3) for plant height, number of leaves and plant girth, respectively. The lowest number of plant growth parameters were observed in control treatment for all four data collection time (19.0, 6.2, and 6.0). According to the results, application of mixtures of bacterial inoculum was effective for enhanced plant growth parameters of tissue culture banana plantlets under greenhouse condition. In addition, two weeks artificial inoculation during in vitro plantlets stage was found the most suitable method for application of microbes with tissue culture banana plantlets which can promote the microbial rhizosphere of banana prior to field plantation.
A numerical approach for solving Nonlinear Optimal Control Problems using the hybrid scheme of Fitness Dependent Optimizer and Bernstein Polynomials

In this paper, a heuristic scheme based on the hybridization of Bernstein Polynomials (BPs) and nature-inspired optimization techniques is presented to achieve the numerical solution of Nonlinear Optimal Control Problems (NOCPs) efficiently. The solution of NOCP is approximated by the linear combination of BPs with unknown coefficients. The unknown coefficients are estimated by transforming the NOCP into an error minimization problem and formulating the objective function. The Genetic Algorithm (GA) and Fitness Dependent Optimizer (FDO) are used for solving the objective function and obtaining the optimum values of the unknown coefficients. The findings and statistical results indicate the represented hybrid scheme offers encouraging results and outperforms the most recent and popular methods proposed in the literature, which ultimately validates the efficacy and productivity of the recommended approach. Furthermore, statistical analysis is incorporated to examine the reliability and stability of the suggested technique. Consequently, the remarkable difference is evident in simplicity, flexibility, and effectiveness compared to the other methods considered.
Hydrocephalus and Growth Retardation: A Fetal RNU4ATAC-opathy Missed by Whole-Exome Sequencing

Introduction: Whole-exome sequencing (WES) is becoming widely available in prenatal diagnosis. However, as with most scientific methods, WES also has its limitations. The aim of the study was to report a fetal case of RNU4ATAC-opathy which was missed by prenatal WES. Case Presentation: A 28-year-old healthy primigravida was revealed by ultrasound at 20 + 3 weeks of gestation to have a fetus with ventriculomegaly (left 15.1 mm/right 11.9 mm), hypoplastic vermis, and mild growth retardation. Chromosomal microarray analysis and trio WES failed to detect a pathogenic copy number variation and sequence variant. A repeat ultrasound at 23 + 3 weeks showed worsened growth delay and hydrocephalus (left 20.3 mm/right 11.0 mm) with vermis hypoplasia and agenesis of corpus callosum. Further study with whole-genome sequencing (WGS) detected 2 missense mutations of the noncoding RNU4ATAC (NR_023343.1) gene, n.51G>A (rs188343279) and n.16G>A (rs750325275), in the fetus, which were inherited from the father and mother, respectively. Discussion: Our study highlights the limitation of WES. WGS might be a clinical option for patients who have a structurally abnormal fetus tested negative by WES.
Measuring change management in manufacturing processes : a measurement method for simulation-game-based process development

The aim of this research is to find an answer to the research problem, which is "How can change management be measured in order to help manufacturing companies develop their manufacturing processes? " To solve the research problem, a constructive action research method is applied. The proposed solution to the research problem, i.e., a change management measurement system, is developed based on principles found in project management literature, process change management literature, performance measurement literature, three consultant surveys, and three case projects. Two of these three case projects applied simulation games as developmental tool, while one applied computer simulation. The proposed change management measurement system is evaluated through these three case projects, and thereafter both practised and further elaborated through two new case projects. The two new case projects are compared for gaining more sophisticated understanding of emerging patterns, and improvement suggestions for simulation-game-based change process utilising the change management measurement system are brought forward. Finally, the results are discussed, and the research and its contribution are evaluated through the quality criteria developed for this research. The measures in the change management measurement system are classified into two types: the first type gauges change project management itself, and the second assesses the outcomes of the change project, i.e., the improvements gained in manufacturing operations. Both of these types are measured in three dimensions: human resources, processes and technology, which are further divided into effectiveness and efficiency. Effectiveness is defined as the external, strategic performance: "doing the right thing," where strategically correct processes are developed, and strategically sound targets are pursued.
THE EFFECT OF ENHANCED EXTENSIVE READING TO THE INCIDENTAL ENGLISH PREPOSITION ACQUISITION

The English prepositions are still problematic for EFL learners since the existing knowledge of their first language hinders them from understanding the use of English prepositions. This study investigated the effect of enhanced extensive reading on their incidental English preposition acquisition. A total of 16 Indonesian University learners of English as a foreign language participated in this study. The treatment lasted for four weeks, initiated with the pretest. Two weeks after the treatment, the posttest was administered, followed by distributing questionnaires to find out the factors influencing them in doing the posttest. The results showed a significant improvement in the students' incidental acquisition of the targeted English prepositions after they received repeated exposure to the English prepositions through enhanced extensive reading. The factors influencing the improvement of their incidental acquisition involve their existing knowledge of the English prepositions and their built intuition in decision making. It is hoped that teachers and educational institutions are encouraged to add extensive reading to their curriculum.
Dietary and Food Consumption Patterns and Their Associated Factors in the Tibetan Plateau Population: Results from 73 Counties with Agriculture and Animal Husbandry in Tibet, China

Dietary imbalances are an important cause of morbidity and mortality, both in China and globally. Abnormal element content in the natural environment and the unbalanced dietary structure of populations coexist in the Tibetan Plateau. This study analyzed the dietary and food consumption patterns of 617 Tibetan residents and their associated factors. Cluster analysis revealed three modes of dietary pattern; the food consumption scores (FCSs) of subjects in modes with relatively high consumption frequency of staple food and relatively singular dietary structure were the lowest. Although the FCSs of most subjects were acceptable (FCS > 35), subjects with relatively low FCSs were more dependent on locally cultivated highland barley that is probably low in selenium. Hierarchical linear models revealed both individual–family and regional factors were significantly related (p values < 0.05) with the food consumption of subjects as follows: age, travel time from township to county, and cultivation area of highland barley were negatively related; numbers of individuals aged 40–60 years and pork, beef, and mutton production were positively related. Individuals with secondary or higher education had higher FCSs. A single indicator may be incomprehensive in dietary and food consumption studies. For people with a relatively unbalanced diet, an analysis of the main foods they consume is critical. Dietary and food consumption patterns might have relatively large inter-regional and intra-regional variations; therefore, factors that influence it might be multi-level and multi-scale.
Clinical Differences Between Elderly and Non-elderly Patients with COVID-19

OBJECTIVE: Comorbidity frequency and mortality rates are higher in elderly patients with COVID-19. The disease is also more severe in elderly patients. This study aims to examine the characteristics of the COVID-19 disease, severity, comorbidities, and mortality rates in elderly patients by comparing them with nonelderly patients. MATERIAL AND METHODS: This study was designed as a retrospective study. 469 patients who were followed up in outpatient, inpatient, and intensive care units with the diagnosis of COVID-19 between March 11, 2020, and June 01, 2020, were retrospectively included in the study. Patients were divided into two groups who were ≥65 years named as the “elderly group” and <65 years referred to as “nonelderly”. Survival data was generated from the death notification system on August 02, 2020. RESULTS: A total of 469 patients including elderly(n=101) and nonelderly(n=368) were included in the study retrospectively. The incidence of severe pneumonia(31%/12.6%) and critical illness(16%/5.8%), comorbidity (85%/37.2%) and hospitalization time(8/5 days) were significantly higher in the elderly group(p<0.05). 23 (22.8%) of elderly patients and 27(7.3%) of nonelderly patients died (p=0.000). Mortality was found to be 3.5 times higher than in the non-elderly group. The expected survival time was 145.85 days(CI 95%:133-158.66) in the elderly patients and 170.36 days(CI 95%:166-174.6) in the nonelderly patients (p<0.000). In ROC analysis, the sensitivity of age was 86%(73.3-94.2), specificity was 66.83%(62.1-71.3), and the cut-off>56 (AUC:0.775; p <0.001) in predicting mortality. CONCLUSION: Mortality is high, comorbidities are more frequent, and the disease is more severe in elderly patients with COVID-19. Age above 56 can be used as a cut-off to predict mortality.
"The Effects of Extracts of Plants (Medicago Sativa, Trigonella Foenum and Carum Carvi) on Milk Production in Dairy Cows"

Lactogenesis in cow is a process in which udder epithelial cells changes from non-secretion to secretion. It widely takes place a little before parturition and produces covering cells of udder alveolus, proteins, fats and lactose and sends them to alveolar duct. Milk synthesis control is affected by hormone axis. Hypophysis hormones especially prolactin, oxytocin, placental lactogen, adrenal steroids, ovarian steroids, growth hormone, thyroxine and insulin play a role in milk synthesis and secretion. At present, use of different plans is populated in medicine and, to some extent, in veterinary. The effective materials of these plants with physiological effects on structure and function of different body tissues and plants are extracted and can be used ssin treating most diseases and preventing them. Traditionally, extract of some plants was used in nursing mothers as a galactagogue. Accordingly, this study considers effects of three Carum Carvi, Trigonella Foenum and Medicago Sativa plants on milk production in dairy cows. For this purpose, 12 Holstein dairy heifer were selected. The heifers, were at the first stage of lactation, kept with the same management and their diet consisted of Medicago Sativa, livestock concentrates. These cows are divided into two placebo and control groups of 6 cows each. These groups were exactly monitored for 8 weeks. The measures include: 1- Preparing plant extract from three Carum Carvi, Trigonella Foenum and Medicago Sativa plants. 2- After milking the cows, the prepared plant extract was orally and daily given to six of control cows at the amount of 60 cc and twice a day (morning and night). This lasted for eight successive weeks. During this period, the amount of milk produced daily by each cow was exactly weighted and recorded. 3- At the end of the every week, i.e. Fridays, blood samples were taken from jugular vein of the groups. They were sent to laboratory to be assayed. This was done for 8 weeks. In laboratory, prolactin and insulin levels of the control and placebo cows was evaluated by Chemiluminance method using ELISA kit (Holzel Diagnostika Company,Germany). blood glucose level was determined with glucose oxidase(GOD) method and inserted in tables. The resulted outcomes indicate increase of 20-40% of daily milk production in control cows (and in some cases more than this amount) due to using the plant extract in six of control cows in comparison with those of placebo that has not received the mentioned plant extract. Additionally, prolactin and insulin levels of control cows and their blood glucose had a 12-25.2% and 3-17% increase, respectively. Increasing of appetite was observed in control cows. They were really fresh, their general conditions and health were noticeable and no undesirable physical changes including undesired color, odor or flavor were observed in control cows' milk.
Within- and between-firm wage inequalities and trade integration in GVC

This paper examines between- (inter) and within- (intra) firm wage inequality using rich employer-employee data for 12 European countries. We confirm that much overall wage inequality is observed within sectors and within occupations. The share of the within- and between-firm components in overall wage inequality varies across countries. We estimate the link between involvement in global value chains (GVCs) and wages differentiating into the within- and between-firm components and test the hypothesis that there is a different effect of GVCs on wages depending on the position in a value chain (close to or far from the final demand). The results indicate that the between-firm wage component is the main channel through which involvement in global value chains is materialised. However, the exact sign of the relationship between GVC growth and wages (conditioned on upstreamness) is country-heterogeneous albeit its marginal economic significance.
Justicia secunda Leaf Aqueous Fraction Suppressed NF-κB, TNF-α, IL-6, and COX-2 in Arthritic Rat

Aims: This study evaluated the effect of the aqueous fraction of Justicia secunda Vahl leaves on selected inflammatory markers Tumor necrosis factor alpha (TNF-α), nuclear factor–kappa B (NF-κB), interleukin-6 (IL-6) and cyclooxygenase-2 (COX-2) and its possible mechanism of action. Study Design: J. secunda aqueous leaf fraction (JSALF) was tested on carrageenan, arachidonic and Complete Freund’s Adjuvant (CFA) induced rat paw inflammation models, respectively. Methodology: Ninety male albino rats (Wistar strain) were randomly distributed into 6 groups of 5 rats each. Group I: normal, administered with 1 mL NaCl, Group II: untreated control, no treatment, Group III: administered with 10 mg/kg body weight (b.wt.) diclofenac sodium (reference drug), Group IV, V, and VI: administered with 200, 400 and 600 mg/kg b.wt. J. secunda leaf aqueous fraction (JSALF), respectively. TNF-α, NF-κB, IL-6 and COX-2 levels were analyzed using enzyme-linked immunosorbent assays (ELISA). Gas Chromatography-Mass Spectrometry (GC-MS) analysis was carried out. Results: JSALF treated animals had significantly (P < .05) suppressed carrageenan, arachidonic and CFA-induced paw edema when compared with untreated control animals. Serum levels of TNF-α, NF-κB, IL-6 and COX-2 were significantly reduced (P < .05) in JSALF-treated animals. GC-MS detected 10 suspected anti-inflammatory compounds. Conclusion: Findings from this study indicate that J. secunda aqueous leaf fraction substantially suppressed pro-inflammatory mediators and COX-2 pathways in arthritic rats which justifies its folkloric use in the management of inflammatory diseases.
