A multiobjective grid interactive solar photovoltaic DSTATCOM system using cascaded observer-based DFLL approach
Authors: Dash Byomakesh , Sharma Renu , Subudhi Bidyadhar 
Published: June 2020

Purpose
A cascaded observer-based transfer delay frequency locked loop (CODFLL) algorithm is developed to control the distribution static compensator (DSTATCOM) to address various power quality (PQ) issues arise because of distorted grid and load conditions. Moreover, frequency locked loop is included along with the observer to take care of the frequency drift from nominal value and to improve its performance during steady state and transient conditions. During daylight, the proposed system works as photovoltaic (PV) DSTATCOM and performs multiple functions for improving PQ whilst transferring power to grid and load. The system under consideration acts as DSTATCOM during night and bad weather condition to nullify the PQ issues.

Design/methodology/approach
CODFLL control algorithm generates reference signal for hysteresis controller. This reference signal is compared with an actual grid signal and a gate pulse is produced for a voltage source converter. The system is made frequency adaptive by transfer delay adaptive frequency locked loop (FLL). Peak power is extracted from a PV source using the perturb and observe technique irrespective of disturbances encountered in the system.

Findings
The PV system’s performance with the proposed controller is studied and compared with conventional control algorithms such as least mean fourth (LMF), improved second-order generalized integrator frequency locked loop (ISOGI-FLL), synchronous reference frame phased lock loop (SRF-PLL) and frequency adaptive disturbance observer (DOB) for different cases, for example, steady-state condition, dynamic condition, variable insolation, voltage sag and swell and frequency wandering in the supply side. It is found that the proposed method tracks the frequency variation faster as compared to ISOGI-FLL without any oscillations. During unbalanced loading conditions, CODFLL exhibits zero oscillations. Harmonics in system parameters are reduced to the level of IEEE standard; unity power factor is maintained at the grid side; hassle-free power flow takes place from the source to the grid and load; and consistent voltage profile is maintained at the coupling point.

Originality/value
CODFLL control algorithm is developed for PV-DSTATCOM systems to generate a reference grid current.
Convergent evolution of niche structure in Northeast Pacific kelp forests
Authors: Starko Samuel , Demes Kyle W. , Neufeld Christopher J. , Martone Patrick T. 
Published: June 2020

AbstractMuch of the morphological and ecological diversity present on earth is believed to have arisen through the process of adaptive radiation. Yet, this is seemingly at odds with substantial evidence that niches tend to be similar among closely related species (i.e. niche conservatism). Identifying the relative importance of these opposing processes in driving niche evolution under different circumstances is therefore essential to our understanding of the interaction between ecological and evolutionary phenomena.In this study, we make use of recent advances in our understanding of the phylogeny of kelps (Laminariales) to investigate niche evolution in one of the most ecologically significant groups of benthic habitat‐forming organisms on the planet. We quantify functional traits and use community sampling data from a kelp diversity hotspot to determine which traits are responsible for the habitat (β) niche of kelps and whether they are labile or conserved across the kelp phylogeny.We find that combinations of functional traits have evolved convergently across kelp subclades and that these functional traits are significant predictors of community structure. Specifically, traits associated with whole‐kelp structural reinforcement and material properties were found to be significantly correlated with species distributions along a gradient of wave disturbance and thus predict the outcome of environmental filtering. However, kelp assemblages were made up of species that are more phylogenetically distinct than expected (i.e. phylogenetic overdispersion), suggesting that niche partitioning along this gradient of wave disturbance has been an important driver of divergence between close relatives.These results are consistent with the hypothesis that environmental filtering associated with wave disturbance plays an essential role in determining the habitat niche of kelps across local communities and further suggest that this process can drive phenotypic divergence and niche partitioning between close relatives. We propose that parallel adaptive radiation of kelp subclades has shaped the diversity and species composition of kelp forests in the Northeast Pacific and we discuss how evidence from the literature on incipient or ongoing speciation events supports this hypothesis.A freePlain Language Summarycan be found within the Supporting Information of this article.
The puzzle of quality upgrading of Chinese exports from the trade liberalization perspective
Authors: Huang Xianhai , Liu Kun , Chen Hangyu 
Published: June 2020

AbstractTrade liberalization could accelerate the process of quality upgrading through the competition effect. However, that the quality of Chinese exports exhibits an opposite performance pattern is puzzling. The present paper uses a framework based on multiproduct firms to analyse the mechanism of how the product quality of exports is affected by trade liberalization to explain this puzzle. The model includes two major mechanisms: the competition effect and the market effect. There is a huge gap in the influence on the product quality of exports between a decrease in tariff barriers and non‐tariff barriers: firms' product quality increases (decreases) when non‐tariff barriers (tariff barriers) fall. The data of Chinese firms from 2001 to 2011 supports this conclusion. Further research reveals that the influence of trade liberalization on the product quality of exports in China varies among different types of firms.
A critical review of the Cochrane meta‐analysis of routine late‐pregnancy ultrasound
Authors: Smith GCS 
Published: June 2020

A Cochrane review of universal late‐pregnancy ultrasound has been highly influential in guiding UK practice, concluding that it does not improve outcome. However, the meta‐analysis combines trials that used diverse definitions of screen positive, were designed in the absence of high‐quality data on diagnostic effectiveness and did not couple screening to an effective intervention. Moreover, even if the trials had combined a highly effective screening test with a highly effective intervention, the sample size was 15% of that required to study perinatal death. It is not known whether universal late‐pregnancy ultrasound confers benefit on the mother or baby.Tweetable abstractDespite >50 years of research, we do not know whether universal late‐pregnancy ultrasound confers benefit on the mother or baby.

Authors: Yang Baohui , Messom Raymond 
Published: June 2020

AbstractObjectiveTo examine patterns of potential primary care (PPC) ED presentations and any association between PPC ED presentations and frequency of general practitioner (GP) care utilisation in New South Wales, Australia.MethodsRetrospective cross‐sectional study of 6 221 762 New South Wales patients who had at least one service in public hospitals, EDs or Medical Benefit Schedule claimable for GP service between 2013/2014 and 2014/2015 is conducted to examine association between PPC ED presentations and GP care utilisation using logistic regression adjusting for comorbidity index and a number of other covariates. Data over 2010/2011 to 2014/2015 are included for analyses of trends and patterns in PPC ED and GP care utilisation.ResultsForty‐one percent of the ED presentations were PPC ED presentations over the 5 years 2010/2011 to 2014/2015. Population rates of PPC ED presentations and GP care both increased over the period, with higher PPC ED presentation rates in regional areas, and higher GP care rates in major cities. GP care utilisation was associated with reduced odds for PPC ED presentations, with the adjusted odds ratios ranging from 0.28 for patients with one GP care service to 0.48 for patients with five or more GP care services compared with patients with none. Increased comorbidity index was also associated with increased risk of PPC ED presentations.ConclusionGP care utilisation was associated with reduced risk for any PPC ED presentations after adjusting for comorbidity index and the other factors.
Dietitians Australia position statement on telehealth

Published: June 2020

AbstractIt is the position of Dietitians Australia that clients can receive high‐quality and effective dietetic services such as Medical Nutrition Therapy (MNT) delivered via telehealth. Outcomes of telehealth‐delivered dietetic consultations are comparable to those delivered in‐person, without requiring higher levels of additional training nor compromising quality of service provision. Dietitians Australia recommends that policy makers and healthcare funders broaden the recognition for telehealth‐delivered dietetic consultations as a responsive and cost‐effective alternative or complement to traditional in‐person delivery of dietetic services. The successful implementation of telehealth can help to address health and service inequalities, improve access to effective nutrition services, and support people with chronic disease to optimise their diet‐related health and well‐being, regardless of their location, income or literacy level, thereby addressing current inequities.

AbstractVector‐borne and zoonotic infectious diseases are serious public health concerns that affect approximately half of the world's population. In particular, arthropod‐borne viruses (arboviruses) have contributed to more mortality and morbidity worldwide with the emergence of dengue, chikungunya, yellow fever, and Zika virus diseases. The infections have scaled up due to urbanization, globalization, and international mobility. Traditionally, the spread of mosquito‐borne viral diseases to humans was considered a low health priority concern. However, their categorization as emerging infectious diseases and public health emergencies of international concern has heightened the attention given by the government, academia, research, and industry for the development of timely, cost‐efficient, and sustainable solutions. The urgency has increased in the wake of global climate change. The focus on effective interventions includes epidemiological monitoring, vector control measures, molecular diagnostics, vaccines, and environmental determinants. In this review, we discuss the etiology and predisposition of mosquito‐borne viruses that are detrimental to public health and economically damaging when disseminated as epidemics. We focus on the large‐scale virus surveillance methods with special reference to innovations and interventions in molecular detection science and technologies that include viral nucleic acid isolation, polymerase chain reaction (PCR)‐based diagnostics, and high‐throughput sequencing technologies. In addition, we discuss the development of a viral RNA extraction and PCR‐based diagnostic kit (Invirustech) that can extract viral RNA from mosquitoes with verified applications in PCR‐based molecular diagnostics of Pan‐flavivirus.

AbstractAtrijuglans hetaohei Yang (Lepidoptera: Gelechioidea), is one of the major pests that seriously damage the walnut fruits. Although the morphology and physiology of A. hetaohei have been widely studied, suitable reference genes for normalizing target gene expression have not been identified. In this study, the expressions of eight candidate reference genes including GAPDH, β‐Tubulin, TATA‐binding protein (TBP), Histone, Ubiquitin‐conjugating enzyme 9 (UBC9), arginine kinase (AK), 28S and elongation factor 1 alpha (EF1α) in different developmental stages and various larval tissues of A. hetaohei were determined using reverse transcription‐quantitative polymerase chain reaction. Moreover, the expression stability of the selected reference genes was evaluated by ΔCt method, BestKeeper, NormFinder, geNorm and ReFinder, a comprehensive software platform. These results demonstrated that the best reference genes were GAPDH and 28S at different developmental stages of A. hetaohei; and the optimum references in various larval tissues of A. hetaohei were 28S, Histone and TBP. Our study should be useful to analyze the expression profiles of target genes and form a solid foundation for future research on the understanding of the genes' biological functions in A. hetaohei.
Agricultural health and medicine education—Engaging rural professionals to make a difference to farmers' lives
Authors: Adams Jessie , Cotton Jacqueline , Brumby Susan 
Published: June 2020

AbstractObjectiveDespite continued higher rates of workplace injuries, earlier morbidity and mortality and challenging climatic environments, few formal programs focus on the health, well‐being and safety of farmers. The agricultural health and medicine unit, developed in 2010, was designed to increase cultural competence and empower rural professionals to improve the health, well‐being and safety outcomes of farming populations in Australia. This study aimed to understand the extent to which graduates (2010‐2018) use the knowledge and skills gained in their current occupations and identify barriers and enablers faced in implementing them.DesignMixed‐methods descriptive study.SettingGraduates were invited to complete an online survey. Following the survey, graduates participated in a phone interview until saturation was reached.ParticipantsForty‐one graduates completed the survey (31% response rate), and eleven interviews were conducted.InterventionsEducation in agricultural health and medicine.Main outcome measuresGraduates use of knowledge and skills gained from the course and the barriers and enablers they experienced in implementation.ResultsThe most represented occupations were nursing, medicine and agriculture (farming). Of respondents, 76% agreed their ability to diagnose, treat or prevent agricultural occupational illness or injury had improved. Positively, 42% use course content professionally at least weekly. Fifty‐one per cent experienced barriers in implementing their new knowledge, and little evidence of career advancement was observed.ConclusionThis study informs the continuous development of the agricultural health and medicine curriculum and highlights the importance of a collaborative and multidisciplinary approach to improving the health, well‐being and safety of farming populations. Despite engaged graduates, the continued high workplace mortality, preventable non‐communicable disease and challenging climatic conditions highlight the need for strategic prioritisation of farmers' health across health, agriculture and policy settings.
The feasibility and safety of early ileostomy reversal: a systematic review and meta‐analysis
Authors: Ng Zi Qin , Levitt Michael , Platell Cameron 
Published: June 2020

AbstractBackgroundRecent evidence supports the safety of early reversal of a temporary stoma, within 14 days of construction. The aim of this systematic review and meta‐analysis was to evaluate the post‐operative morbidity and overall feasibility of early stoma reversal.MethodsMedline and Cochrane databases were searched for studies up to June 2019 that investigated the outcomes of early stoma reversal (EC, defined as closure ≤14 days from the index operation) versus late stoma reversal (LC, ≥8 weeks from the index operation). Meta‐analysis was performed on the respective rates of post‐operative morbidity, anastomotic leak, wound infection, bleeding, sepsis, small bowel obstruction and ileus.ResultsNine studies were included (667 patients analysed). Meta‐analysis showed no significant difference in the post‐operative morbidity rate, anastomotic leak rate, rates of small bowel obstruction, bleeding and ileus between EC and LC. However, the wound infection rate was significantly higher after EC than LC; relative difference 0.10 (95% confidence interval 0.00–0.19, P = 0.047). The stoma‐related complication rate was significantly higher after LC than EC; relative difference −0.28 (95% confidence interval ‐0.45 to −0.11, P = 0.001).ConclusionThe concept of early stoma reversal is appealing, and this meta‐analysis confirms the safety of early stoma closure with an associated reduction in stoma‐related complications despite higher wound infection rates. However, the results need to be interpreted with caution due to the heterogeneity of the studies included, especially in respect of the definition of complications that were used. Further well‐designed prospective studies are required prior to confident adoption of early stoma closure into clinical practice.

AimsThe clinically investigated rationale for neprilysin (NEP)‐inhibition by angiotensinreceptor‐NEPinhibitor (ARNi) therapy is to induce elevations in endogenous natriuretic peptides. NEP, however, cleaves a broad spectrum of substrates, which partially hold significant implications in heart failure with reduced ejection fraction (HFrEF). The effect of NEP inhibition on these peptides has not been investigated thoroughly. This study explored the response of adrenomedullin (ADM) regulation to the initiation of ARNi.MethodsSeventy‐four patients with stable HFrEF and initiation of ARNi were prospectively enrolled, 67 patients on continuous angiotensin‐converting‐enzyme inhibitor(ACEi)/angiotensin‐receptor blocker (ARB) therapy served as control. Plasma bioactive‐ADM (bio‐ADM), mid‐regional‐pro‐ADM (MR‐proADM), B‐typenatriuretic peptide (BNP) and N‐terminal‐pro‐BNP (NT‐proBNP) were determined at baseline, short‐term, 1‐year and 2‐year follow up.ResultsFollowing ARNi initiation both bio‐ADM and MR‐proADM concentrations were significantly increased at early and long‐term follow up (bio‐ADM [pg/mL]: 26.0 [interquartile range {IQR}: 17.7–37.5] vs. 50.8 [IQR: 36.5–78.1] vs. 54.6 [IQR: 42.0–97.1] vs. 57.4 [IQR: 48.5–161.6]; MR‐proADM [nmol/L]: 0.87 [IQR: 0.64–1.12] vs. 1.25 [IQR: 0.93–1.79] vs. 1.42 [IQR: 0.95–1.90] vs. 1.60 [IQR: 1.12–2.46], P < .0001 for all). The ratios bio‐ADM/MR‐proADM and BNP/NT‐proBNP increased during ARNi‐therapy proving improved availability of bioactive peptides. The proportional increase of bio‐ADM markedly exceeded BNP increase. Patients converted to ARNi showed similar biomarker patterns irrespective of baseline renin–angiotensin system blocker therapy, i.e. ACEi or ARB (P > .05 for all), indicating that activation of the ADM‐axis arises particularly from NEPinhibition.ConclusionThe significant increase of MR‐proADM and bio‐ADM together with an elevated bioADM/MR‐proADM ratio suggest both enhanced formation and reduced breakdown of bioactive ADM following the initiation of ARNi. Activation of the ADM‐axis represents a so far unrecognized effect of ARNi.
Two worlds collide? The role of Chinese traditions and Western influences in Chinese preservice teachers’ perceptions of appropriate technology use
Authors: Dong Chuanmei , Mertala Pekka 
Published: June 2020

AbstractThis study reports Chinese preservice teachers’ perceptions of appropriate technology use in early childhood education (ECE). China provides an interesting but understudied research context as research into technology use in the early years is western‐centric and the contemporary Chinese ECE is characterized as a hybrid combining traditional Chinese values and Western influences which differ from each other in a rather fundamental manner. Interpretive analysis of qualitative interviews with eight purposefully selected preservice teachers revealed three intertwining determinants as appropriate technology use: objective, time and context. Both, Chinese cultural traditions and Western educational ideas were evident in shaping the participants’ perceptions of appropriate technology use, with the former being the major influence in restraining the preservice teachers’ vision and understanding of technology integration. Implications for teacher education, educational policies and future research are discussed.
Trends, patterns, and networks of illicit wildlife trade in Nepal: A national synthesis

Published: June 2020

AbstractIllicit wildlife trade may have devastating consequences for Nepal's wildlife populations given its increasing national and global connectivity and proximity with large Indian and Chinese markets. Despite its potential impacts, our understanding about trends, patterns and networks of illicit wildlife trade in Nepal is very limited. Here, we provide a thorough and comprehensive national assessment of such trade in Nepal using 5 years (2011 through 2015) of data on wildlife seizures and arrests (n = 830) collected from 73 districts. Nearly 87% of arrests included seizures, and globally threatened species were confiscated from 56% of total arrests. There were increasing trends of arrest cases over the time period for all species (p = 0.03), leopards (p = 0.02) and red pandas (p = 0.002), and a decreasing trend for rhinoceros (p = 0.04). Seizures of multiple species—especially tigers, leopards, and pangolin—in arrest cases were suggestive of international organized criminal linkages, whereas individual small‐scale seizures were likely for local, species‐specific markets. The trade networks suggested connections between species core habitats (poaching sites), cities (collection sites), and transit routes between India and China (international markets). Our results show that wildlife trade, except for rhinoceros, is increasing and trade nodes along districts bordering China and India are suggestive of large, international networks.
