A Unified Modeling Method of Virtual Synchronous Generator for Multi-Operation-Mode Analyses

To provide inertia support for the grid, virtual synchronous generator (VSG) control of inverter-interfaced distributed generators (IIDGs) becomes a focus of worldwide attention. However, a VSG-based IIDG behaves differently in the grid-connected (GC) mode, the islanded-single-DG mode, and the islanded-multi-DG mode, whereas the mathematical and physical interpretations of this phenomenon are not well studied. In this article, we propose a unified modeling method of VSG-based IIDG to analyze its different dynamic performance in each operation mode. The proposed unified formulas can obtain the state-space models of the islanded-single-DG and islanded-multi-DG modes from that of GC mode for any VSG control method. With the obtained models, for several different types of VSG control in different operation modes, we analyze the distribution and sensitivity of the closed-loop poles and investigate the step responses both analytically and experimentally. These analyses reveal the intrinsic differences and correlations of the dynamics of VSG-based IIDG between each operation mode. These intrinsic features are valid independent of the applied VSG control scheme; thus, a test method to evaluate the parameters and performance of an unknown IIDG is derived. The findings of this article provide important instructions for engineers to model and design and test multi-operation-mode distributed generators.
A novel, noninvasive, mRNA gene expression colon cancer screening methodology.

3631 Background: An mRNA gene expression methodology testing noninvasive rectal swab samples for a panel of 16 genes, representing 4 metabolic pathways, has shown promise for detecting colon and rectal cancers in pilot studies. To test the screening potential of this methodology, we conducted a case-controlled, single-center study using samples collected from patients with a negative screening colonoscopy (Controls; n = 71) and from patients with colorectal cancer (CRC; n = 38). Methods: Controls were defined as polyp- and cancer-free patients with no family history of CRC. Rectal swabs were collected, coded, preserved in RNAProtect O solution (Qiagen), and RNA was isolated using RNeasy mini kit (Qiagen). Real time RT-PCR using reverse transcriptase (Invitrogen) and random primers and Oligo (dT) was performed on samples pretreated with RNAase-free DNase. PCR amplification with specific oligonucleotide primers was performed using Applied Biosystems 7500 Fast Real-Time PCR Systems for 16 different markers i.
Las ocupaciones laborales en función de los requisitos de competencias lingüísticas: una categorización mediante redes neuronales artificiales

Este trabajo tiene como objetivo agrupar las distintas ocupaciones laborales en diversas categorías en función de la semejanza en los requisitos que presenta cada ocupación en cuanto a competencias lingüísticas. Para ello, se utilizan los datos para las ocupaciones definidas en la O’Net-SOC-2010 para EE.UU. en 2015. Se consideran tres clasificaciones, en función del nivel de desagregación que presentan los datos de O’Net. El análisis se efectúa mediante redes neuronales artificiales, en concreto, los mapas autoorganizativos de Kohonen (SOM). Se pretende así analizar si el nivel de desagregación de las ocupaciones influye en la clasificación de dichas ocupaciones en función del nivel requerido de competencias lingüísticas. La aportación que se realiza es novedosa, ya que, hasta donde conocemos, no existe ningún trabajo previo que utilice los SOM para la clasificación de las ocupaciones laborales considerando las competencias lingüísticas requeridas. Dicho análisis puede ayudar a los investigadores sociales en el estudio del impacto e influencia que presentan los componentes lingüís- ticos del trabajo en la productividad laboral, la empleabilidad de los trabajadores, los resultados empresariales y la generación de ventajas competitivas basadas en el lenguaje, entre otras.
Stress management group therapy on job satisfaction and general health in nurses

Background & Aim: Stress management is one of the effective methods on health and job satisfaction of Health staff. Stress management through group therapy on health and job satisfaction of staff has been less investigated. Thus, the aim of this study is to investigate the effect of stress management group therapy on nurses' job satisfaction and general health. Methods: This is a quasi-experimental study which conducted on 20 nurses of 9-Day hospital in Torbat Heydariyeh city. At first, two standard questionnaires of general health (Goldberg and Hillier) and job satisfaction (Linz) were completed by both intervention and control groups. The intervention group participated in 8 sessions of stress management group therapy and the control group received no intervention. After the end of the last session of group therapy, two questionnaires were completed by both groups again. Data were analyzed using descriptive statistics and independent and paired T-test using SPSS software version 20. Results: The mean and standard deviation of participants' age was 38±7.50. Before the study, two groups were not significantly different in terms of background. At the beginning of the study, job satisfaction and general health scores of intervention and control groups were not different (p>0.05). There was no significant difference between job satisfaction and general health in control group, before and after the study. However, there was a significant difference between two mentioned variables in the intervention group (p<0/05). Stress management group therapy increased job satisfaction and general health of nurses. Conclusion: Based on the results, it is recommended that stress management techniques should be applied to increase job satisfaction and general health among nurses.
Employer branding and its relation with HR functions of employee recruitment and retention: A review of literature

The current recruitment scenario, which is highly dynamic and challenging, calls for the attention of academics and practitioners alike. Recently, several studies were conducted to understand the possible relationship between employer branding and employee retention (Gilani & Cunningham, 2017; Wilden, Gudergan, & Lings, 2010). In the present study, an attempt has been made to explore the impact of employer branding on employee recruitment and retention. A comprehensive literature review of previous studies on this topic was conducted, in an attempt to understand the influence of employer branding on each aspect of recruitment. For this purpose, concepts from signalling theory, person-organisation fit and social identity were considered. Careful analysis of previous studies reveals that employer branding has an impact on an organisation's ability, not only to recruit, but also to retain, desired employees. Further, the organisations which are able to successfully project their images as potential employers of choice are bound to reap benefits in the long run.
The Whole is Greater than the Sum of its Parts - Synergies between Non-Digital and Digital Business Models within Companies

Digital transformation is increasingly becoming a major concern for established companies. Part of the digital transformation is often the creation of new business models based on digital technologies, which do not replace the established business model but act as additional source of revenue. Two concurrent business models within one company creates the opportunity of synergies between these business models. However, knowledge on interactions between two business models, specifically digital and nondigital, remains in an embryonic stage. This multicase study, based on companies from various industries and size, addresses this shortcoming. Following the business model canvas and the theories of resource relatedness and complementarity, we show how both business models can propel each other thanks to value and cost synergies between them. Finally, we offer rich insights for practitioners on what type of synergies they can benefit from and present guidelines they can use to identify and unlock these synergies.

Comparing Effects of Enteral and Parenteral Nutrition in Patients Admitted to Intensive Care Units: A Systematic Review

Background: With regard to critical illness and stress, medication side effects, decreased appetite, and increased nausea and vomiting; patients admitted to intensive care units (ICUs) are at particular risk of malnutrition. Feeding behavior i.e. time and method in these patients has still remained as an unresolved issue. Thus; enteral and parenteral nutrition, with their own benefits and complications, are two commonly used methods for such individuals. The present systematic review was to compare the effects of enteral and parenteral nutrition in patients admitted to ICUs. Methods: This systematic review investigated a total number of 1642 articles on nutrition methods in ICU patients during 2010-2019 using keywords of “enteral nutrition, parenteral nutrition solutions, parenteral nutrition, critical care outcomes, critical illness, intensive care unit, and ICU” in the databases of SID, Iranmedex, MEDLIB-ED, PubMed, Scopus, Medline, Embase, Cochrane, Web of Science, and Google Scholar; and finally, 15 articles were analyzed in relation to the research objectives. Results: Studies indicated that patient mortality was not different in enteral and parenteral nutrition groups. The incidence rate of infectious complications was also reported higher in parenteral nutrition group. However, there was no significant difference in the incidence rate of infections in studies meeting total standards for parenteral nutrition. Besides, there was no significant difference between the duration of undergoing mechanical ventilation and hospitalization time in both groups. Furthermore, the incidence rate of hypoglycemia was higher in enteral nutrition group; but serum protein levels had much better status compared with those in parenteral nutrition group. Conclusion: If standards for infusion are observed and provided that rates of infectious complications are reduced, patients can benefit from starting parenteral nutrition immediately after admission to ICUs in the absence of enteral method.
The complete mitochondrial genome of Choroterpides apiculata (Ephemeroptera: Leptophlebiidae) and its phylogenetic relationships

Abstract The complete mitochondrial genome of Choroterpides apiculata (Ephemeroptera: Leptophlebiidae) is typically a circular molecule of 15,199 bp in length, containing 37 genes (13 protein-coding genes, 22 tRNAs, and two rRNAs) and one control region. The overall A + T content of the whole genome is 74% and the A + T content of the control region is 79.7%. In Bayesian inference and maximum-likelihood phylogenetic trees using 24 species from 13 families of Ephemeroptera, the monophyly of the families Isonychiidae, Heptageniidae, Vietnamellidae, Leptophlebiidae, Caenidae, and Baetidae were highly supported and C. apiculata was a sister group to Habrophlebiodes zijinensis.

This research is quasi-experimental in a non-equivalent control group design. The sampling technique uses cluster random sampling. This research was conducted in the fourth grade of Elementary School 13, Tanjung Barulak, Tanah Datar, Indonesia. The results showed that there is an influence of make-a-match cooperative learning model using Prezi in elementary school. Research implication is as an additional reference for teachers and education practitioners in developing learning models in the classroom during Industry 4.0.
Understanding the Experiences of the Community-Dwelling Older Adults of the FallProofTM Program

Background : One in three community-dwelling older adults aged 65 years or older experience at least one fall per year, leading to fall-related injuries, loss of independence, and, in some instances, death. Effective interventional strategies exist to prevent falls and their negative consequences in community-dwelling older adults. The FallProof™ program is a balance and mobility program for fall prevention offered through the Calgary Fall Prevention Clinic to community-dwelling older adults who have a history of falls. Although evidence established the effectiveness of this program in reducing fall risks, little is known about the perspectives of community-dwelling older people with respect to the program. Objective : To explore the perspectives of community-dwelling older adults with a history of falls of a twelve- week FallProof™ program led by physiotherapists. Method : A qualitative description approach was used to explore the perspectives of ten community-dwelling older participants (seven women and three men) aged 65+ years who completed the 12- week FallProof™ program . Participants were recruited using a purposive sampling method. Individual interviews were conducted at participants’ homes, using a semi-structured interview guide . The interviewer’s observations during the interview sessions and reflective ideas were documented in field notes. I nterviews and participants’ observation data from the field notes were transcribed verbatim. Data were analyzed using the constant comparative technique. Results : The overall theme, “A n award-winning program ” was identified. Three categories supported this theme: 1) Participants experience fall-related benefits; 2) A variety of activities and great instructors empowered participation; and 3) Deterrents to participation.
The Impact of CGPI Award towards Financial Performance of LQ45 Firms

Corporate governance is highly recommended by the government for large companies in Indonesia. Very few companies that have IPOs in Indonesia apply corporate governance, so there is still little research that addresses the impact of corporate governance on corporate performance. The researcher tried to analyze the impact of corporate governance on the financial performance of companies listed on LQ45. Analysis uses company samples taken from 2015-2017. From previous research, it can be indicated that the implementation of corporate governance has a positive and significant influence on company performance. However, from this analysis, the results show that the Corporate Governance Perception Index (CGPI) Award has no effect on ROA, this is different from other variables such as the percentage of independent commissioners and the size of the board that have a positive effect on ROA of companies registered with LQ45.

Explainable Machine Learning Approach as a Tool to Understand Factors Used to Select the Refractive Surgery Technique on the Expert Level

Purpose Recently, laser refractive surgery options, including laser epithelial keratomileusis, laser in situ keratomileusis, and small incision lenticule extraction, successfully improved patients’ quality of life. Evidence-based recommendation for an optimal surgery technique is valuable in increasing patient satisfaction. We developed an interpretable multiclass machine learning model that selects the laser surgery option on the expert level. Methods A multiclass XGBoost model was constructed to classify patients into four categories including laser epithelial keratomileusis, laser in situ keratomileusis, small incision lenticule extraction, and contraindication groups. The analysis included 18,480 subjects who intended to undergo refractive surgery at the B&VIIT Eye center. Training (n = 10,561) and internal validation (n = 2640) were performed using subjects who visited between 2016 and 2017. The model was trained based on clinical decisions of highly experienced experts and ophthalmic measurements. External validation (n = 5279) was conducted using subjects who visited in 2018. The SHapley Additive ex-Planations technique was adopted to explain the output of the XGBoost model. Results The multiclass XGBoost model exhibited an accuracy of 81.0% and 78.9% when tested on the internal and external validation datasets, respectively. The SHapley Additive ex-Planations explanations for the results were consistent with prior knowledge from ophthalmologists. The explanation from one-versus-one and one-versus-rest XGBoost classifiers was effective for easily understanding users in the multicategorical classification problem. Conclusions This study suggests an expert-level multiclass machine learning model for selecting the refractive surgery for patients. It also provided a clinical understanding in a multiclass problem based on an explainable artificial intelligence technique. Translational Relevance Explainable machine learning exhibits a promising future for increasing the practical use of artificial intelligence in ophthalmic clinics.
Effects of white, yellow, and blue colored LEDs on milk production, milk composition, and physiological responses in dairy cattle.

Light emitting diode (LED) is more energy efficient than incandescent or fluorescent light. This study was to evaluate effects of different colored LEDs on milk production, milk composition, and physiology of Holstein cow. According to milk production and parity, cows (n = 186) were allotted to four treatments: control (natural daylight), white, yellow, and blue LED groups. Of these, 40 cows that had passed 57 day-in-milk were used. Yellow and blue LED groups demonstrated greater rates of decline in milk production than control and white LED groups. At the finish point, milk fat, protein, and lactose contents were the lowest in the blue LED group, whereas milk-urea-nitrogen levels were the highest in the yellow and blue LED groups. Extended exposure to blue LED light lowered antioxidant enzyme activity and insulin-like growth factor-1 levels. Prolactin concentrations were higher in the white and blue LED groups than in the control. Cortisol level was the highest in the blue LED group among the groups. Nonesterified fatty acid levels in the yellow and blue LED groups decreased to the greatest extent compared to the start point. These results suggest that blue LED light can decrease milk production and generate more stress than white and yellow LED lights.
Social Equity Impacts of Congestion Management Strategies

Author(s): Shaheen, Susan, PhD; Stocker, Adam; Meza, Ruth | Abstract: This white paper examines the social equity impacts of various congestion management strategies. The paper includes a comprehensive list of 30 congestion management strategies and a discussion of equity implications related to each strategy. The authors analyze existing literature and incorporate findings from 12 expert interviews from academic, non-governmental organization (NGO), public, and private sector respondents to strengthen results and fill gaps in understanding. The literature review applies the Spatial – Temporal – Economic – Physiological – Social (STEPS) Equity Framework (Shaheen et al., 2017) to identify impacts and classify whether social equity barriers are reduced, exacerbated, or both by a particular congestion mitigation measure. The congestion management strategies discussed are grouped into six main categories, including: 1) pricing, 2) parking and curb policies, 3) operational strategies, 4) infrastructure changes, 5) transportation services and strategies, and 6) conventional taxation. The findings show that the social equity impacts of certain congestion management strategies are not well understood, at present, and further empirical research is needed. Congestion mitigation measures have the potential to affect travel costs, commute times, housing, and accessibility in ways that are distinctly positive or negative for different populations. For these reasons, social equity implications of congestion management strategies should be understood and mitigated for in planning and implementation of these strategies.
