Intraguild interference of spiders and ladybirds in a cotton field: Evidence from their active time and aphid control efficiency
Authors: Wang Guifeng , Dong Zhaoke , Li Lili , Lu Zengbin , Li Chao , Men Xingyuan 
Published: October 2021

AbstractIn field crop systems, biocontrol efficiency supported by various predators is not always enhanced with occurring simultaneously but can be reduced by predator interference, i.e., competition between predator individuals over access to their prey. Such interference may be related to the active time of each predator. In this study, predator exclusion experiments were used to selectively exclude either one or both predators and to examine the impact of the two predator groups on the suppression of cotton aphid (Aphis gossypii Glover) populations in a cotton field. Main predator species included Propylaea japonica (Thunberg) and Harmonia axyridis Pallas in the ladybird group, and Lycosa spp. and Erigone spp in the spider group. A greater number of spiders was observed in the morning and evening, while ladybird densities did not vary during the day. Removing all predators led to an increase in aphid numbers compared to the other treatments where predators were present. Removing either spiders or ladybirds had similar impacts on aphid control. It is likely that spiders provide an equal level of aphid mortality as ladybirds. When both spiders and ladybirds were present, aphid abundance did not differ from those treatments where only one predator group was present. The presence of both predators did not lead to more aphid suppression, indicating that interference between these predators may have occurred in the cotton field. Although these two predators partly diverged in their activity rhythms, interference may still have occurred and could be common in cotton fields.

Authors: Djudin Tomo , Kartono Kartono 
Published: October 2021

Digital citizenship has become a priority in education almost all over the world. This study aims to explore the level of perception of prospective teacher students regarding digital citizenship and analyze differences in the level of perception of digital citizenship in terms of gender, educational background, and various regional geographical characteristics. This research applies descriptive method with survey-explorative study. A total of 345 student teacher candidates in the sixth semester of the 2020/2021 Academic Year at Westkalimantan of Educational Personnel Education Institute (LPTK) were involved as samples. To explore the level of perceptions of digital citizenship of prospective teachers, this study adopted a questionnaire of Likert scale. Based on data analysis, it was found; (1) the perception profile of students (prospective teachers) about digital citizenship is quite varied; (2) there is no significant difference in the level of perceptions between female and male students; (3) there are significant differences in the level of student perception in terms of various educational backgrounds and geographical conditions from the area where they live. Prospective teachers need to be trained on the knowledge, skills, and values of digital citizenship before they provide learning services in schools.
Generation of Shakedown Boundaries of Thin-Walled 90-Deg Scheduled Pipe Bends Determined Via Large and Small Displacement Finite Element Models
Authors: Abdalla Hany Fayek 
Published: October 2021

Abstract
The present research investigates the effect of employing large displacement in finite element modeling on the generated shakedown (SD) boundaries of thin-walled 90-deg scheduled pipe bends. A recently developed methodology termed: shakedown limit—plastic work dissipation (SDLimit−PWD) method generates the SD boundaries via employing the large displacement in the finite element (FE) simulations. Additionally, a well-established direct noncyclic technique termed: shakedown direct noncyclic technique (SD_DNT) generates the SD boundaries via employing the small displacement formulation in the FE simulations. Comparing the SD boundaries generated via both methods illustrated a marked increase in the generated SD domains due to employing large displacement.

ObjectivesTo date, many artificial intelligence (AI) systems have been developed in healthcare, but adoption has been limited. This may be due to inappropriate or incomplete evaluation and a lack of internationally recognised AI standards on evaluation. To have confidence in the generalisability of AI systems in healthcare and to enable their integration into workflows, there is a need for a practical yet comprehensive instrument to assess the translational aspects of the available AI systems. Currently available evaluation frameworks for AI in healthcare focus on the reporting and regulatory aspects but have little guidance regarding assessment of the translational aspects of the AI systems like the functional, utility and ethical components.MethodsTo address this gap and create a framework that assesses real-world systems, an international team has developed a translationally focused evaluation framework termed ‘Translational Evaluation of Healthcare AI (TEHAI)’. A critical review of literature assessed existing evaluation and reporting frameworks and gaps. Next, using health technology evaluation and translational principles, reporting components were identified for consideration. These were independently reviewed for consensus inclusion in a final framework by an international panel of eight expert.ResultsTEHAI includes three main components: capability, utility and adoption. The emphasis on translational and ethical features of the model development and deployment distinguishes TEHAI from other evaluation instruments. In specific, the evaluation components can be applied at any stage of the development and deployment of the AI system.DiscussionOne major limitation of existing reporting or evaluation frameworks is their narrow focus. TEHAI, because of its strong foundation in translation research models and an emphasis on safety, translational value and generalisability, not only has a theoretical basis but also practical application to assessing real-world systems.ConclusionThe translational research theoretic approach used to develop TEHAI should see it having application not just for evaluation of clinical AI in research settings, but more broadly to guide evaluation of working clinical systems.

Published: October 2021

BackgroundAvascular necrosis (AVN) can impact up to 50% of patients with sickle cell disease (SCD) and can result in significant pain, decline in physical function and decreased quality of life. While hyaluronic acid (HA) has been used in the adult population for shoulder osteoarthritic pain, we present the first published pediatric case of HA injections in the glenohumeral joint, used to improve function and pain control.Case presentationThe patient is a 12-year-old woman with SCD, who suffered from chronic pain due to AVN of the humeral and femoral head. Despite engaging in a multidisciplinary pain management plan, she continued to have severe decline in physical functioning and became a wheelchair user. As a result, she was scheduled for a right total hip arthroplasty, which necessitated aggressive postoperative therapies using the glenohumeral joint. To improve this pain and to facilitate postoperative recovery, the patient underwent 4 weekly HA injections into the glenohumeral joint. Over a 2-month period, the patient was able to improve physical functioning, decrease opiate use and participate in all postoperative therapies.ConclusionConservative options to improve functioning and pain are especially important in pediatric patients where it may be desirable to delay surgical interventions until skeletal maturity. Our case report demonstrates the benefits of intra-articular HA as part of a multidisciplinary pain management plan to improve function and decrease pain related to AVN of the humeral head. Future studies should assess the long-term benefits of HA injections for AVN in the setting of SCD.

In clinical trials of heart failure reduced ejection fraction (HFrEF), ivabradine seemed to be an effective heart rate lowering agent associated with lower risk of cardiovascular death. In contrast, ivabradine failed to improve cardiovascular outcomes in heart failure preserved ejection fraction (HFpEF) despite the significant effect on heart rate. This meta-analysis is the first to compare the effects of ivabradine on heart rate and mortality parameters in HFpEF versus HFrEF. We screened three databases: PubMed, Embase, and Cochrane Library. The outcomes of these studies were mortality, reduction in heart rate, and left ventricular function improvement. We compared the efficacy of ivabradine treatment in HFpEF versus HFrEF. Heart rate analysis of pooled data showed decrease in both HFrEF (–17.646 beats/min) and HFpEF (–11.434 beats/min), and a tendency to have stronger bradycardic effect in HFrEF (p = 0.094) in randomized clinical trials. Left ventricular ejection fraction analysis revealed significant improvement in HFrEF (5.936, 95% CI: [4.199–7.672], p < 0.001) when compared with placebo (p < 0.001). We found that ivabradine significantly improves left ventricular performance in HFrEF, at the same time it exerts a tendency to have improved bradycardic effect in HFrEF. These disparate effects of ivabradine and the higher prevalence of non-cardiac comorbidities in HFpEF may explain the observed beneficial effects in HFrEF and the unchanged outcomes in HFpEF patients after ivabradine treatment.

Published: October 2021

<p><span lang="EN-US">A stable operation of wind turbines connected to the grid is an essential requirement to ensure the reliability and stability of the power system. To achieve such operational objective, installing static synchronous compensator static synchronous compensator (STATCOM) as a main compensation device guarantees the voltage stability enhancement of the wind farm connected to distribution network at different operating scenarios. STATCOM either supplies or absorbs reactive power in order to ensure the voltage profile within the standard-margins and to avoid turbine tripping, accordingly. This paper present new study that investigates the most suitable-location to install STATCOM in a distribution system connected wind farm to maintain the voltage-levels within the stability margins. For a large-scale squirrel cage induction generator squirrel-cage induction generator (SCIG-based) wind turbine system, the impact of STATCOM installation was tested in different places and voltage-levels in the distribution system. The proposed method effectiveness in enhancing the voltage profile and balancing the reactive power is validated, the results were repeated for different scenarios of expected contingencies. The voltage profile, power flow, and reactive power balance of the distribution system are observed using MATLAB/Simulink software. </span></p>

Published: October 2021

Background and Purpose:
The net benefit of carotid endarterectomy (CEA) is determined partly by the risk of procedural stroke or death. Current guidelines recommend CEA if 30-day risks are <6% for symptomatic stenosis and <3% for asymptomatic stenosis. We aimed to identify prediction models for procedural stroke or death after CEA and to externally validate these models in a large registry of patients from the United States.

Methods:
We conducted a systematic search in MEDLINE and EMBASE for prediction models of procedural outcomes after CEA. We validated these models with data from patients who underwent CEA in the American College of Surgeons National Surgical Quality Improvement Program (2011–2017). We assessed discrimination using C statistics and calibration graphically. We determined the number of patients with predicted risks that exceeded recommended thresholds of procedural risks to perform CEA.

Results:
After screening 788 reports, 15 studies describing 17 prediction models were included. Nine were developed in populations including both asymptomatic and symptomatic patients, 2 in symptomatic and 5 in asymptomatic populations. In the external validation cohort of 26 293 patients who underwent CEA, 702 (2.7%) developed a stroke or died within 30-days. C statistics varied between 0.52 and 0.64 using all patients, between 0.51 and 0.59 using symptomatic patients, and between 0.49 to 0.58 using asymptomatic patients. The Ontario Carotid Endarterectomy Registry model that included symptomatic status, diabetes, heart failure, and contralateral occlusion as predictors, had C statistic of 0.64 and the best concordance between predicted and observed risks. This model identified 4.5% of symptomatic and 2.1% of asymptomatic patients with procedural risks that exceeded recommended thresholds.

Conclusions:
Of the 17 externally validated prediction models, the Ontario Carotid Endarterectomy Registry risk model had most reliable predictions of procedural stroke or death after CEA and can inform patients about procedural hazards and help focus CEA toward patients who would benefit most from it.

Published: October 2021

American University Discourse in the COVID-19 Pandemic: Multimodal AspectThis paper examines the transformations that have taken place in the multimodal representation of American university discourse during the COVID-19 pandemic. The first part of the paper investigates how the traditional realization of American university discourse has changed during the coronavirus pandemic. The second part of the paper focuses on the structure, content, role, and characteristic features of the multimodal texts which have been created by American universities as social institutions and have been published on their websites and social media accounts during the pandemic. Overall, it is assumed that during the pandemic the content of the analyzed texts has gradually changed from active propaganda for complete isolation at home to the cautious promotion of reconnecting in a secure surrounding on campus. Amerykański dyskurs uniwersytecki w pandemii COVID-19: aspekt multimodalnyAutorka analizuje przemiany, które zaszły w multimodalnej reprezentacji amerykańskiego dyskursu uniwersyteckiego podczas pandemii COVID-19. W pierwszej część artykułu bada, jak tradycyjna realizacja amerykańskiego dyskursu uniwersyteckiego zmieniła się podczas pandemii koronawirusa. W drugiej części artykułu skupia się na strukturze, treści, roli i charakterystycznych cechach tekstów multimodalnych, które zostały wytworzone przez amerykańskie uniwersytety jako instytucje społeczne i opublikowane na własnych stronach internetowych i kontach w mediach społecznościowych w czasie pandemii. Na podstawie analizowanych tekstów autorka zauważa, że ich treść zmieniała się stopniowo: od aktywnego propagowania całkowitej izolacji w domu do ostrożnego promowania ponownego łączenia się w bezpiecznym otoczeniu na terenie kampusu.

Western Region Variety of the Standard Ukrainian Language in the Interwar Period: A Review of Liudmyla Pidkuĭmukha’s Monograph Mova Lʹvova, abo koly ĭ batiary hovoryly (Kyiv: Klio, 2020, ss. 326)The reviewed monograph is the first extensive paper on the vocabulary of the western variant of the Ukrainian language based on the texts of the ‘Twelve’, an interwar literary circle of writers from Lʹviv. The paper highlights the social dialects that functioned in Lʹviv during the interwar period, in particular the jargon of schoolchildren and athletes. Particular attention is paid to balak, which became a linguistic feature of the Batyar subculture. This subculture reached its peak in the 1920s and 1930s. Material collated from three editions of B. Nyzhankivskyi’s collection Street (1936, 1941, 1995) illustrates the specifics of Soviet editorial practice, which was aimed at limiting the use of western Ukrainian vocabulary in order to artificially bring the Ukrainian language closer to Russian.

Introduction: Nucleated red blood cells (NRBC) are rare in the peripheral circulation of healthy individuals and their presence have been associated with mortality in adults and very low birth weight newborns, however, its value as a biomarker for mortality in infants requiring veno-arterial (VA) extracorporeal membrane oxygenation (ECMO) has yet to be studied. We sought to determine if NRBC can serve as a biomarker for ECMO mortality and inpatient mortality in infants requiring V-A ECMO. Methods: A single-center retrospective chart review analyzing infants <1 year of age requiring VA ECMO due to myocardial dysfunction or post-cardiotomy between January 1, 2011 to June 30, 2020. Results: One hundred two patients required VA ECMO. Sixty-five patients required ECMO post-cardiotomy, 19 for perioperative deterioration, and 18 for myocardial dysfunction. Fifty-one patients (50%) died (21 died on ECMO, 30 died post-ECMO decannulation). Multivariable analysis found Age < 60 days (OR 13.0, 95% CI 1.9–89.6, p = 0.009), NRBC increase by >50% post-ECMO decannulation (OR 17.1, 95% CI 3.1–95.1, p = 0.001), Single Ventricle (OR 9.0, 95% CI 1.7–47.7, p = 0.01), and lactate at ECMO decannulation (OR 3.0, 95% CI 1.3–7.1, p = 0.011) to be independently associated with inpatient mortality. ROC curves evaluating NRBC pre-ECMO decannulation as a biomarker for mortality on ECMO (AUC 0.80, 95% CI 0.68–0.92, p  ⩽ 0.001) and post-ECMO decannulation (AUC 0.75, 95% CI 0.65–0.84, p  ⩽ 0.001) show NRBC to be an accurate biomarker for mortality. Conclusions: Greater than 50% increase in NRBC post-ECMO decannulation is associated with inpatient mortality. NRBC value pre-ECMO decannulation may be a useful biomarker for mortality while on ECMO and post-decannulation.
