Fault Tolerant and Nano Displacement Drive Control Method of Photoelectric Motor for Battery Electric Vehicle
Authors: Liu Weiping , Wang Zhaofeng , Zhang Ximing , Wang Yulin , Hu Bochun , Zhuang Ye
Published: June 2021

The low-resolution photoelectric position sensor is used, that is, Hall position sensor replaces the traditional photoelectric encoder and other high-resolution position sensors to monitor the rotor position. However, because the three-phase Hall position sensor can only output six
position signals, a hardware circuit design of low-resolution position sensor monitoring rotor position signal is proposed. Meanwhile, nanotechnology has been introduced in the study of micro drive of battery electric vehicle (BEV). BEV driver has some disadvantages such as hysteresis, creep
and nonlinearity, which seriously affects its application in nano environment. A nano displacement sensor is designed for the characteristics of BEV driver. The nonlinear problem of micro driver is solved through the closed-loop control of position feedback. In the test, through the verification
of rotor position and current waveform, it can be proved that the method based on photoelectric position sensor and rotor position signal monitoring can ensure the low deviation of rotor position calculation and correct output signal of three-phase photoelectric position sensor. The decoupling
performance of vector control is verified by 3/2 transformation. In the displacement detection of micro driver, the designed nano displacement sensor has higher resolution and its performance is better than that of the previous three generations of displacement sensors.
Algorithm for Graph’s Connectivity Problem Based on DNA Origami
Authors: Ma Jingjing
Published: June 2021

Based on DNA origami, an algorithm is proposed for Graph’s Connectivity problem via the self-assembly of DNA origami structures. The desired DNA origami structures can be constructed. These structures can encode the information of Graph’s vertices and edges, because these
structures have sticky ends, so they can assemble to advanced structures representing the information of a graph via specific hybridization. Via strand displacement reaction and agarose gel electrophoresis, the vertices can be deleted and the graph’s connectivity can be tested one by
one. This is a highly parallel method, and can reduce the complexity of Graph’s Connectivity problem greatly.
A Fast Linear Semi-Lagrangian Advection Scheme Coupled with Spectral (bin) Microphysics to Simulate an Idealized Super Cell Storm in WRF

Published: June 2021

A new, computationally efficient Semi-Lagrangian advection (SLA) scheme was used to simulate an idealized supercell storm using WRF coupled with Spectral (bin) Microphysics (SBM). SLA was developed to make complicated microphysical schemes more computationally accessible to cloud resolving models. The SLA is a linear combination of Semi-Lagrangian schemes of the first and the second order. It has relatively low numerical diffusion, a high level of mass conservation accuracy, and preserves the sum of multiple advected variables. In addition to idealized tests, comparisons were made with standard WRF higher-order, non-linear advection schemes. Tests of the SLA were performed using different weighting coefficients of γ for the combination of the first and second order components. The results of SLA on grids of 1 km, 500 m, and 250 m agree well with those of the standard WRF advection schemes, with results most similar to simulations with 250 m grid spacing. At the same time, the advection CPU time required by the SLA was 2.2 to 3 times shorter than the WRF advection schemes. The speed-up occurred in part because of the utilization of the same advection matrix for the advection of all hydrometeor mass bins. The findings of this work support the hypothesis that cloud microphysical simulation is more sensitive to the choice of microphysics than to the choice of advection schemes, thereby justifying the use of computationally efficient lower order linear schemes.
The Preventive Effect of Alprostadil on the Contrast-Induced Nephropathy of Coronary Heart Disease Treated by Percutaneous Coronary Intervention in Moderate and High-Risk Population Stratified by Mehran Score
Authors: Liu Xiaogang , Zhang Peng , Zhang Jing , Zhang Xue , Yang Shicheng , Fu Naikuan
Published: June 2021

The Mehran risk score (MRS) was used to classify patients with coronary heart disease and evaluate the preventive effect of alprostadil on contrast-induced nephropathy (CIN) after percutaneous coronary intervention. The patients (n = 1146) were randomized into an alprostadil and control group and then divided into 3 groups on the basis of the MRS: low-risk, moderate-risk, and high-risk groups. The primary end point was the occurrence of CIN (alprostadil + hydration vs simple hydration treatment); secondary end points included serum creatinine, blood urea nitrogen, creatinine clearance rate, cystatin C, interleukin-6, C-reactive protein, proteinuria, and differences in the incidence of major adverse events. In the low-risk, moderate-risk, and high-risk groups, the incidence of CIN in the control and alprostadil group was 2.9 versus 2.6% ( P = .832), 11.4 versus 4.9% ( P = .030), 19.1 versus 7.7% ( P = .041), respectively. Multivariate logistic regression analysis showed that alprostadil treatment was a favorable protective factor for moderate-risk and high-risk CIN patients (OR = 0.343, 95% CI: 0.124-0.951, P = .040). Alprostadil can be used as a preventive treatment for moderate- and high-risk CIN patients classified by the MRS. The reduction of CIN by alprostadil may be related to an anti-inflammatory effect.
Poisson Diagnostic Classification Models: A Framework and an Exploratory Example
Authors: Liu Ren , Liu Haiyan , Shi Dexin , Jiang Zhehan
Published: June 2021

Assessments with a large amount of small, similar, or often repetitive tasks are being used in educational, neurocognitive, and psychological contexts. For example, respondents are asked to recognize numbers or letters from a large pool of those and the number of correct answers is a count variable. In 1960, George Rasch developed the Rasch Poisson counts model (RPCM) to handle that type of assessment. This article extends the RPCM into the world of diagnostic classification models (DCMs) where a Poisson distribution is applied to traditional DCMs. A framework of Poisson DCMs is proposed and demonstrated through an operational dataset. This study aims to be exploratory with recommendations for future research given in the end.
Treatment alliance and needs of care concerning religiousness and spirituality: A follow-up study among psychiatric inpatients
Authors: van Nieuw Amerongen-Meeuse Joke C , Braam Arjan W , Anbeek Christa , Twisk Jos WR , Schaap-Jonker Hanneke
Published: June 2021

Background:

Patient satisfaction with religious/spiritual (R/S) care during mental health treatment has been associated with a better treatment alliance.

Aims:

To investigate the longitudinal relations between (un)met R/S care needs and treatment alliance/compliance over a 6-month period.

Method:

201 patients in a Christian (CC) and a secular mental health clinic completed a questionnaire (T0) containing an R/S care needs questionnaire, the Working Alliance Inventory (WAI) and the Service Engagement Scale (SES). After 6 months 136 of them took part in a follow-up (T1). Associations were analysed using hybrid linear mixed models and structural equation modelling.

Results:

R/S care needs decreased over time, but a similar percentage remained unanswered (e.g. 67% of the needs on R/S conversations in a secular setting). Over a 6-month period, met R/S care needs were associated with a higher WAI score (β = .25; p < .001), and unmet R/S care needs with lower WAI score (β = −.36; p < .001), which were mainly between subjects effects. Patients reporting a high score of unmet R/S care at baseline, reported a decrease in SES over time (β = −.13; p < .05).

Conclusions:

Satisfaction with R/S care among mental health patients is related to a better treatment alliance. When unmet R/S care needs persist, they precede a decrease in treatment compliance. Mental health professionals are recommended to assess the presence of R/S care needs and consider possibilities of R/S care especially in the first weeks of treatment.
When Must One Permit Scandals to Arise? A Comparison of Two Traditions
Authors: Anderson Justin M.
Published: June 2021

The essay argues that were a bishop to consult the treatment of scandal in the manuals of moral theology of the last several centuries, he could easily find rational justification for an ecclesial cover-up. Given the manualists’ overwhelming emphasis on avoiding scandal, Peter Cantor’s (d. 1197) triplex veritas—a threefold truth one may never abandon despite scandals arising—offers the beginning of a necessary corrective rationale. While not abandoning the insights of the manual writers altogether, the lost medieval tradition of the triplex veritas should be revived to correct the unidirectional rationale regarding the avoidance of scandal.
A travel-related infection case associated with triple vector-associated infections: Malaria–Dengue–Zika virus
Authors: Şanlıdağ Gamze , Sipahi Oĝuz Reşat
Published: June 2021

As international travels and destinations increase, travel-related infections increase. It is reported that 6–87% of the travellers contract travel-related infection during or after the trip. Vector-associated pathogens comprise a significant percentage of travel-related infections. Apart from the ubiquitous COVID19, threats such as Dengue, Chikungunya and Zika virus and tick-borne agents have emerged or re-emerged in recent years. The fact that these infections are carried with similar vectors and cause similar symptoms makes diagnosis difficult. Herein, a case of travel-associated infection with nonspecific symptoms is presented.
Thyroglossal Duct Cyst Papillary Carcinoma With Airway Compromise
Authors: Huang Po-Kai , Hsieh Li-Chun , Leu Yi-Shing
Published: June 2021

Thyroglossal duct cysts are typically benign and usually asymptomatic. Malignant transformation is uncommon. Intralaryngeal extension is rare and results in dysphonia or dyspnea. There is no literature nowadays reporting the thyroglossal duct cyst carcinoma combining the clinical features of intralaryngeal extension. The authors present a case of progressive hoarseness and midline neck mass for 2 years. The laryngoscope and computed tomography revealed a 6-cm thyroglossal duct cyst containing ectopic thyroid tissue with intralaryngeal extension and causing airway obstruction. Complete excision with Sistrunk operation revealed papillary thyroid carcinoma. The patient resumed normal phonation after the surgery. There was no evidence of tumor recurrence and no hoarseness or dyspnea at 6 months follow up. This is the first reported case of a huge thyroglossal duct cyst carcinoma with intralaryngeal extension causing airway compromise. Complete excision of tumor is essential and vital to the symptom relief. A thyroglossal duct cyst carcinoma with endolaryngeal involvement should be considered in the differential diagnosis when the case has a massive midline neck mass with ectopic thyroid tissue and develops dyspnea or hoarseness concurrently.
The multiple temporalities of infrastructure: Atomic cities and the memory of lost futures
Authors: Dawney Leila
Published: June 2021

Nuclear power plants, with their promise of boundless cheap energy, are archetypal figures of progress modernity. As we acknowledge the limits of industrial progress and growth-based capital, places for where the dream is now over, and whose inhabitants are finding ways of living through its transition, offer emergent practical ontologies based on maintenance, bricolage and necessity. Through the case study of the atomic city of Visaginas, Lithuania, this paper addresses the question of how to account for forms of life that emerge in the aftermath of high modernity. Here, infrastructures operate as residual cultural and material resources for practical ontologies and world building after progress. Building on emerging scholarship on the political aesthetics of infrastructure, I suggest that their ontological transition involves what Fisher describes as the ‘memory of lost futures’, a future anterior that, through the remains of material connections, technocultures and cultural memory, provide limits and conditions for emergent ways of living ‘after progress.’
A systematic review on long-term clinical impact in patients with iliofemoral deep vein thrombosis
Authors: Charisis Nektarios , Harb Hussein , Harb Muhammed , Labropoulos Nicos
Published: June 2021

Objective

The aim of this systematic review was to investigate the long-term clinical impact of iliofemoral (IF) deep vein thrombosis (DVT) based on patient reported outcomes, physician administered test measures and compare medical to interventional treatment.

Methods

This study was conducted according to the Preferred Reporting Items for Systematic Reviews (PRISMA) guidelines. Criteria for inclusion were patients with thrombus involving the common femoral vein or more proximal veins, ≥5-year follow-up and physician assessment. Data quality was assessed using the Robins-I tool and Cochrane tool.

Results

Eight studies that fulfilled our criteria were deemed eligible and provided data for 499 patients. There were 230 patients who received medical treatment and 269 interventional. Two studies were randomized controlled trials and six observational. Venous claudication, where reported, was found in 7.7% (1/13) of interventionally treated patients and 21% (13/62) of medically treated patients. Long term symptom resolution was reported in 58% (18/31) and 24% (12/50) of interventionally and medically treated patients, respectively. Venous ulcers were seen in 5.5% (7/126) of medically treated patients and 5% (5/100)of interventionally treated patients.

Conclusion

A wide range of signs and symptoms was reported at long-term. Interventional treatment appeared to be better than medical one but the evidence was weak. Given the significant lack of patient reported outcomes, objective testing and use of validated instruments, the results should be interpreted in context with these limitations. Data on long-term outcomes after IF DVT have been poorly reported and outcome criteria should be better defined in future studies.
The diagnosis of early pneumoconiosis in dust-exposed workers: comparison of chest radiography and computed tomography
Authors: Hayashi Hideyuki , Ashizawa Kazuto , Takahashi Masashi , Kato Katsuya , Arakawa Hiroaki , Kishimoto Takumi , Otsuka Yoshinori , Noma Satoshi , Honda Sumihisa
Published: June 2021

Background

Chest radiography (CR) is employed as the evaluation of pneumoconiosis; however, we sometimes encounter cases in which computed tomography (CT) is more effective in detecting subtle pathological changes or cases in which CR yields false-positive results.

Purpose

To compare CR to CT in the diagnosis of early-stage pneumoconiosis.

Material and Methods

CR and CT were performed for 132 workers with an occupational history of mining. We excluded 23 cases of arc-welder’s lung. Five readers who were experienced chest radiologists or pulmonologists independently graded the pulmonary small opacities on CR of the remaining 109 cases. We then excluded 37 cases in which the CT data were not sufficient for grading. CT images of the remaining 72 cases were graded by the five readers. We also assessed the degree of pulmonary emphysema in those cases.

Results

The grade of profusion on CR (CR score) of all five readers was identical in only 5 of 109 cases (4.6%). The CR score coincided with that on CT in 40 of 72 cases (56%). The CT score was higher than that on CR in 13 cases (18%). On the other hand, the CT score was lower than that on CR in 19 cases (26%). The incidence of pulmonary emphysema was significantly higher in patients whose CR score was higher than their CT score.

Conclusion

CT is more sensitive than CR in the evaluation of early-stage pneumoconiosis. In cases with emphysema, the CR score tends to be higher in comparison to that on CT.
Health Professionals’ Recommendations for a Dementia Plan for China
Authors: Zhao Wenhong , Wu Min-Lin , Petsky Helen , Moyle Wendy
Published: June 2021

There is no specific national dementia plan concerning people with dementia in China. The purpose of this study was to explore health professionals’ recommendations for a dementia plan for China to meet the needs of people with dementia. Semi-structured interviews were conducted with 24 doctors and nurses using purposive maximum variation sampling. Data were interpreted inductively using thematic analysis. Four themes were identified. Themes on policy recommendations emphasized a need to support people with dementia and those who care for them, including the development of community daycare centers, specialized dementia care units in hospitals, and specialized nursing homes. Improvement in dementia care in China is needed, including services across all care settings. Programs to train and support family caregivers and help health professionals to detect, diagnose and treat dementia are crucial. Further support for the families of people with dementia is required.
Experimental studies on direct expansion solar thermal heat pump systems using R430A as a substitute to R134a
Authors: Mohanraj M , Kartheheyan I M
Published: June 2021

The use of halogen-based refrigerants in heat pump applications is restricted because of their high global warming potential (GWP). Therefore, it is necessary to identify a low GWP substitute for heat pump applications. This article presents the energy performance of a direct expansion solar thermal heat pump system (DXSTHPS) using R430A as an environmentally friendly substitute to phase out R134a. The effects of ambient parameters on compressor discharge temperature, compressor energy consumption, condenser heating capacity and coefficient of performance (COP) of a DXSTHPS using R134a and R430A are estimated and compared. Moreover, the total equivalent global warming impacts (TEGWI) of a DXSTHPS using R134a and R430A are evaluated. The results showed that the R430A has 0.7–1.9% lower compressor energy consumption than R134a. The condenser heating capacity and COP of a DXSTHPS using R430A are higher than R134a by 4.6–8.7% and 5.1–10.2%, respectively. The compressor discharge temperature observed in a DXSTHPS using R430A is 5.8 °C higher than R134a. The lubricant physical properties are retained at higher compressor operating temperatures, ensuring compressor reliability. The DXSTHPS using R430A has 4.2–12.9% lower TEGWI due to its lower GWP with lower compressor energy consumption than R134a.
Biomechanical evaluation of stress distributions at the implant-abutment complex and peri-implant bone around mandibular dental implants with different neck geometries and inclinations
Authors: Dinc Murat M , Turkoglu Pinar , Selvi Firat
Published: June 2021

This study aimed to investigate the effects of the different dental implant neck designs, diameters, and inclinations, on the stress distributions at the mandibular crestal bone and implant-abutment complex, using three-dimensional (3D) finite element stress analysis (FEA) method. Finite element models of three-unit fixed partial dentures supported with two same length implants (10 mm), placed on the second premolar and second molar regions, were designed. Eight different models were designed according to the implants’ neck designs (platform switching/traditional), diameters (4.1 mm/4.8 mm) and the tilting angles of the posterior implants (0°/15°). The anterior implants’ widths were 4.1 mm and the neck design of the anterior implants matched the posterior implants. Two types of 100-N loads in vertical and 30° oblique directions were applied separately onto each central fossae and functional cusps of the fixed partial dentures crowns. Algor Fempro Software was used for the simulation and evaluation of the stress levels at the implant-abutment complex and the crestal bone. Stress levels measured at the crestal bone were found to be lower for the platform switching models. However, the platform switching design generated higher stress magnitudes within the implant-abutment complex. Inclined placement of posterior implants increased the amount of stress at the crestal bone around both implants. Biomechanically, selection of the largest diameter possible when using tilted platform switched implants may be recommended at the posterior mandible.
Let’s Talk About Each Other: Neural Responses to Dissenting Personality Evaluations Based on Real Dyadic Interactions
Authors: Schindler Sebastian , Höhner Anne , Moeck Robert , Bruchmann Maximilian , Straube Thomas
Published: June 2021

Dyadic interactions are associated with the exchange of personality-related messages, which can be congruent or incongruent with one’s self-view. In the current preregistered study ( N = 52), we investigated event-related potentials (ERPs) toward real social evaluations in order to uncover the neural mechanisms underlying the processing of congruent and incongruent evaluative feedback. Participants interacted first, and then during an electroencephalogram (EEG) session, they received evaluations from their interaction partner that were either congruent or incongruent with their own ratings. Findings show potentiated processing of self-related incongruent negative evaluations at early time points (N1) followed by increased processing of both incongruent negative and positive evaluations at midlatency time windows (early posterior negativity) and a prioritized processing of self-related incongruent positive evaluations at late time points (feedback-related P3, late positive potential). These findings reveal that, after real social interactions, evaluative feedback about oneself that violates one’s self-view modulates all processing stages with an early negativity and a late positivity bias.
When ‘the show’ cannot go on: An investigation into sports mega-events and responses during the pandemic crisis
Authors: Lee Ludvigsen Jan Andre
Published: June 2021

This article examines the relationship between sports mega-events and the coronavirus disease-2019 pandemic. Focusing primarily on the 2020 Summer Olympics and Union of European Football Associations Euro 2020 in football – representing two mega-events that were postponed due to the pandemic – this article explores the emerging discourses from sport governing bodies, and how these organisations communicated their initial responses to the pandemic between February and May 2020. The article takes a digital qualitative research approach and draws upon frame analysed media sources and public communications. As it proceeds, this article first illuminates how global sports entered a temporary standstill and, second, how sport governing bodies positioned themselves with regard to responding to the global crisis from within the sporting sphere. Subsequently, this article emphasises how the relevant responses, as communicated by sport governing bodies, reflected the broader reactive and adaptive pandemic responses apparent within socio-political fields.
Is public procurement fit for reaching sustainability goals? A law and economics approach to green public procurement
Authors: Halonen Kirsi-Maria
Published: June 2021

Green public procurement is assumed to have a strong steering effect. The recent EU Green Deal contains proposals to amend green public procurement rules from voluntary to mandatory regulation, which has been endorsed by several legal scholars. At the same time, the effectiveness of green public procurement as an environmental policy tool has been studied in economics, where research results present a reserved approach towards green public procurement’s effectiveness. This article examines green public procurement applying a law and economics methodology, with the goal of combining the approaches from different disciplines and finding ways in which environmental objectives can be effectively addressed through procurement regulation. The main conclusions are that the steering effect, costs and potential environmental impact of green public procurement vary in different industries and therefore a sector-specific approach should be adopted in the development of green public procurement regulation. In order to encourage companies to invest and develop their operations in a greener direction, it is important that a large number of contracting authorities use harmonized green public procurement criteria. Further, the effects of green public procurement regulation on competition and emissions from the private consumer market should be monitored and the potential of public procurement to achieve environmental objectives should be explored and compared with other policy options.
Leveraging the Added Value of Experiential Co-Curricular Programs to Humanize Medical Education
Authors: Senok Abiola , John-Baptiste Anne-Marie , Al Heialy Saba , Naidoo Nerissa , Otaki Farah , Davis Dave
Published: June 2021

Background: The aftermath of the 1910 Flexner report resulted in significant gaps in the structure of medical education. Experiential co-curricular opportunities can contribute to addressing these gaps. Purpose: To explore, from a holistic social constructionism perspective, the added value of a co-curricular program, designed and implemented based on Kolb’s Experiential Learning Theory. Methodology/Approach: In this case study, randomly selected medical students, who had participated in an experiential co-curricular program, undertook focus group sessions. Data were inductively analyzed using thematic analysis based on constructivist epistemology. Findings/Conclusions: Benefits at the individual/student level included three interlinked themes: personal, academic, and professional development. The personal development theme related to building character and resilience, and the academic development theme related to application of theory and previously acquired knowledge. Four categories surfaced within the professional development theme. Emergent categories at the community level were institutional advancement, contribution to host centers, and giving back to the community. Implications: Co-curricular programs, that are based on Kolb’s Experiential Learning Theory (ELT) and that foster learning as participation in the social world, humanize medical education, and nurture holistic millennial physicians.
Batch-based agile program management approach for coordinating IT multi-project concurrent development
Authors: Yang Qing , Bi Yingxin , Wang Qinru , Yao Tao
Published: June 2021

Software development projects have undergone remarkable changes with the arrival of agile development approaches. Many firms are facing a need to use these approaches to manage entities consisting of multiple projects (i.e. programs) simultaneously and efficiently. New technologies such as big data provide a huge power and rich demand for the IT application system of the commercial bank which has the characteristics of multiple sub-projects, strong inter-project correlation, and numerous project participating teams. Hence, taking the IT program management of a bank in China as a case, we explore the methods to solve the problems in multi-project concurrent development practice through integrating the ideas of program and batch management. First, to coordinate the multi-project development process, this paper presents the batch-based agile program management approach that synthesizes concurrent engineering with agile methods. And we compare the application of batch management between software development projects and manufacturing process. Further, we analyze the concurrent multi-project development practice in the batch-based agile program management, including the overlapping between stages, individual project’s activities, and multiple projects based on common resources and environment to stimulate the knowledge transfer. Third, to facilitate the communication and coordination of batch-based program management, we present the double-level responsibility organizational structure of batch management.
A mode I crack with multiple islands of ideal contact between the crack faces: An asymptotic model
Authors: Argatov Ivan
Published: June 2021

The problem of a mode I crack having multiple contacts between the crack faces is considered. In the case of small contact islands of arbitrary shapes, which are arbitrarily located inside the crack, the first-order asymptotic model for the crack opening displacement is constructed using the method of matched asymptotic expansions. The case of a penny-shaped crack has been studied in detail. A scaling hypothesis for the compliance reduction factor is formulated.
Unraveling Genome Evolution Throughout Visual Analysis: The XCout Portal
Authors: Diaz-del-Pino Sergio , Perez-Wohlfeil Esteban , Trelles Oswaldo
Published: June 2021

Due to major breakthroughs in sequencing technologies throughout the last decades, the time and cost per sequencing experiment have reduced drastically, overcoming the data generation barrier during the early genomic era. Such a shift has encouraged the scientific community to develop new computational methods that are able to compare large genomic sequences, thus enabling large-scale studies of genome evolution. The field of comparative genomics has proven itself invaluable for studying the evolutionary mechanisms and the forces driving genome evolution. In this line, a full genome comparison study between 2 species requires a quadratic number of comparisons in terms of the number of sequences (around 400 chromosome comparisons in the case of mammalian genomes); however, when studying conserved syntenies or evolutionary rearrangements, many sequence comparisons can be skipped for not all will contain significant signals. Subsequently, the scientific community has developed fast heuristics to perform multiple pairwise comparisons between large sequences to determine whether significant sets of conserved similarities exist. The data generation problem is no longer an issue, yet the limitations have shifted toward the analysis of such massive data. Therefore, we present XCout, a Web-based visual analytics application for multiple genome comparisons designed to improve the analysis of large-scale evolutionary studies using novel techniques in Web visualization. XCout enables to work on hundreds of comparisons at once, thus reducing the time of the analysis by identifying significant signals between chromosomes across multiple species. Among others, XCout introduces several techniques to aid in the analysis of large-scale genome rearrangements, particularly (1) an interactive heatmap interface to display comparisons using automatic color scales based on similarity thresholds to ease detection at first sight, (2) an overlay system to detect individual signal contributions between chromosomes, (3) a tracking tool to trace conserved blocks across different species to perform evolutionary studies, and (4) a search engine to search annotations throughout different species.
Influence of the study abroad bilingual experience on cognitive control among young adults
Authors: Xie Zhilong , Dong Yanping
Published: June 2021

Aims and objectives/purpose/research questions:

This study investigated whether the studying abroad bilingual experience among unevenly balanced Chinese–English bilinguals exerted influence on cognitive control.

Design/methodology/approach:

We compared cognitive control differences between a group of Chinese–English bilinguals (n = 30) studying abroad in the USA and a control bilingual group (n = 30) studying at home in mainland China by administering the Flanker task and the Wisconsin Card Sorting Test (WCST). The two groups were matched on demographic variables including age, socioeconomic status (SES), intelligence, etc.

Data and analysis:

A mixed ANOVA was applied to the Flanker task data, with the task condition as the within-subject variable and the participant group as the between-subject variable. Independent t-test analyses were used to compare performance differences between groups on the WCST.

Findings/conclusions:

The two groups performed similarly on the Flanker task, whereas the group studying abroad fared better on the WCST, indicating better mental set shifting.

Originality:

This is the first study to show that the experience of studying abroad brings about cognitive control advantage in mental set shifting.

Significance/implications:

The current research provides the first evidence that the experience of studying abroad is related to the enhancement of cognitive control, which has implications for both cognitive development and international education.
Birds and places: What the lexicon reveals about multilingualism
Authors: Döhler Christian
Published: June 2021

Aims and objectives:

The paper describes the current multilingual language ecology and explores two subdomains of the lexicon in order to infer information about the extent and nature of multilingualism in the past.

Methodology:

The paper employs quantitative and qualitative analysis of a sociolinguistic questionnaire in the first part. The second part includes a qualitative analysis of lexemes in the domains of bird names and plant names, and then compares them with old ethnographic sources as well as recent information on the surrounding languages.

Data:

The data of this study come from original fieldwork by the author in the village of Rouku and surrounding villages collected between 2010 and 2016. It is supplemented by material from colleagues working on related languages (Evans, Kashima and Siegel).

Findings:

The method suggests that the type of multilingualism that was practiced in the past is similar to today.

Originality:

The study is novel in providing a description of multilingualism from the Southern New Guinea area. Moreover, it advances a lexicographic and ethnographic approach in reconstructing the past state of a language ecology.

Implications:

The main conclusion is that in the absence of written historical sources – a problem that one is almost always facing in New Guinea – it is possible to extrapolate from the lexicon of Komnzo to a past state of the local language ecology.

Limitations:

The method does not allow for dating the point in time for which the inferences can be made.
Impact of screening on short-term mortality and morbidity following treatment for colorectal cancer
Authors: Wilhelmsen Michael , Njor Sisse Helle , Roikjær Ole , Rasmussen Morten , Gögenur Ismail
Published: June 2021

Background and objective:

The aim of this study was to describe short-term changes in morbidity and mortality associated with the implementation of screening for colorectal cancer in Denmark.

Methods:

Prospective cohort study with inclusion of all patients aged 50–75 years treated for colorectal cancer between 1 March 2014 and 31 December 2015 in Denmark. Adjusted hazard ratios were calculated for 30 and 90 days mortality using Cox Regression. We made two adjusted models—a “basic” adjusted for screening status, sex, age, smoking, alcohol consumption, and cancer type and an “advanced” that also included body mass index and American society of Anesthesiologists score in analyses. Relative risks were calculated for postoperative surgical and medical complications.

Results:

In total, 5348 patients were included. In the “basic model,” adjusted risk of 30 and 90 days total mortality was reduced in the screen-detected group (p < 0.01, HR = 0.43, CI = 0.24–0.76) and (p < 0.01, HR = 0.45, CI = 0.30–0.69). In the “advanced model,” only 90 days total mortality was significantly reduced in the screen-detected group (p = 0.01, HR 0.59, CI = 0.39–0.90). No significant changes were found with regard to surgical and medical complications, respectively, (p = 0.05 (CI = 0.76–1.00) and p = 0.47(CI = 0.74–1.15)).

Conclusions:

This nationwide study showed that screening for colorectal cancer was associated with a lower 90 days total mortality although no significant improvements were seen with regard to morbidity.
Evaluating the Performance of Five Asset-based Wealth Indices in Predicting Socioeconomic Position in Rural Bangladesh
Authors: Woolard Katherine , Munira Shirajum , Jesmin Khaleda , Hruschka Daniel
Published: June 2021

Social scientists have developed numerous asset-based wealth indices to assess and target socioeconomic inequalities globally. However, there are no systematic studies of the relative performance of these different measures as proxies for socioeconomic position. In this study, we compare how five asset-based wealth indices—the International Wealth Index (IWI), the Standard of Living portion of the Multi-Dimensional Poverty Index (MPI-SL), the Poverty Probability Index (PPI), the Absolute Wealth Estimate (AWE), and the DHS Wealth Index (DHS)—predict benchmarks of socioeconomic position across 11 communities in rural Bangladesh. All indices were highly correlated.

Authors: Faulkner Harrison , Graham David J. , Hile Mark , Lawson Richard D. , Sivakumar Brahman S.
Published: June 2021

Intra-articular fracture dislocations of the base of the middle phalanx are complex and debilitating injuries that present a management conundrum when nonreconstructable. Hemi-hamate arthroplasty (HHA) is a treatment modality of particular use in the setting of highly comminuted fractures. This systematic review aims to summarize the reported outcomes of HHA in this context. A literature search was conducted using MEDLINE, Embase, and PubMed, yielding 22 studies with 235 patients for inclusion. The weighted mean postoperative range of movement at the proximal interphalangeal joint was 74.3° (range, 62.0°-96.0°) and at the distal interphalangeal joint was 57.0° (range, 14.0°-80.4°). The weighted mean postoperative pain Visual Analog Scale was 1.0 (range, 0.0-2.0). The weighted mean postoperative grip strength was 87.1% (range, 74.5%-95.0%) of the strength on the contralateral side. Posttraumatic arthritis was reported in 18% of cases, graft collapse in 4.2%, and donor site morbidity in 3.0%, with a mean follow-up period of 28.4 months (range, 1-87 months). Hemi-hamate arthroplasty is a reliable and effective technique for the reconstruction of intra-articular base of middle phalangeal fracture dislocations, affording symptomatic relief and functional restoration. Further research is required to assess the true incidence of long-term complications.

One of the pathways to achieve social impact of research is based on a meaningful citizen engagement, especially with main stakeholders, from early stages through all of the project. Scale-up evidence-based educational practices with social impact is a key challenge for systemic change and yet remains understudied in academic literature. This article aims to explore dialogic methods for citizen engagement in educational research, through the case of the scalability of the Successful Educational Actions identified on INCLUD-ED research (FP6, 2006–2011) in 139 schools in Portugal, from 2017 to 2020. Data collection includes document analysis, communicative observation, and interviews. Findings highlight the dialogue maintained not only between schools and researchers but also a multidirectional dialogue between schools that have already implemented research results and schools willing to replicate them and also among government, trainers, and other agents from the community. We identify three features of this multidirectional dialogue: it maintains an evidence-based approach, it is based on egalitarian dialogue, and it is clearly oriented toward the improvement of educational quality for all. The multidirectional dialogue perspective illustrates key methodological issues to take into account during the replicability and scalability of research to enhance its social impact.

Objectives

Vascular calcification is a well-known phenomenon and affects coronary and carotid arteries as well as other arterial beds. Presence of arterial calcification is associated with major adverse events in patients undergoing percutaneous coronary artery or carotid artery intervention. Even though there is a clear association between worse outcome and coronary-carotid calcification, there is no research that interrogated the relationship between iliac arterial calcification and clinical outcomes because of lack of data. Therefore, in this study, we aimed to investigate the impact of iliac arterial calcification on procedure success rates and long-term outcomes among patients undergoing endovascular intervention.

Methods

The records of 453 consecutive patients who underwent endovascular intervention due to symptomatic peripheral artery disease were analyzed. Patients were divided into two groups based on the presence or absence of heavy calcification of iliac arteries. For each group, technical aspects of procedures and subsequent clinical outcomes were analyzed.

Results

According to our study, the rate of restenosis following endovascular intervention at 6 and 12 months were similar between two groups. On the other hand, long-term restenosis was significantly higher in patients with heavy calcification of iliac arteries as compared to patients with low calcification on iliac arteries (32.2% vs. 12.8%, p <  0.05).

Conclusions

Our data showed that there was a strong association between heavy calcification of iliac arteries and long-term restenosis in patients undergoing endovascular intervention.

Published: June 2021

Tingling, pain and numbness in the hand can be a major cause of morbidity for many people. Adequate hand and wrist function are required for a huge variety of daily tasks, therefore disorders of the hand and wrist can have significant detrimental effects on the quality of life for affected individuals. With any upper limb issue, it is important to consider hand dominance, occupation and pastimes of the affected person. This article focuses on the optimal diagnosis and management of carpal and cubital tunnel syndromes from a primary care perspective.
Studies of electrical, thermal, and mechanical properties of single-walled carbon nanotube and polyaniline of nanoporous nanocomposites

Hydrogel of single-walled carbon nanotubes and polyaniline has been used for thermopower engineering applications due to desirable thermal, electrical, and mechanical properties as well as tunable degradability. In this article, we fabricated nanoporous composite scaffolds from hydrogel of single-walled carbon nanotubes and polyaniline polymer using a standard in situ polymerization process. Our solution-based fabrication method prevented single-walled carbon nanotube aggregation which resulted in enhancing thermal, electrical, and mechanical properties with keeping optimum flexibility in the porous composite scaffold. We compared the mechanical, electrical, and thermal properties of nanoporous composites with different single-walled carbon nanotube loadings. The porous composite scaffold with a 25 wt% showed higher electrical conductivity, ultimate tensile strength, and tensile modulus. Lastly, our solution fabrication method prevents aggregation single-walled carbon nanotube and could help to build the thermoelectrical materials for flexible electronic applications.
An Examination of the Glucose Management Indicator in Young Children with Type 1 Diabetes
Authors: Monzon Alexandra D. , Patton Susana R. , Clements Mark
Published: June 2021

Background:

Previous studies utilizing glucose data from continuous glucose monitors (CGM) to estimate the Glucose Management Indicator (GMI) have not included young children or determined appropriate GMI formulas for young children with type 1 diabetes (T1D).

Methods:

We extracted CGM data for 215 children with T1D (0-6 years) from a repository. We defined sampling periods ranging from the 3-27 days prior to an HbA1c measurement and compared a previously established GMI formula to a young child-specific GMI equation based on the sample’s CGM data. We examined associations between HbA1c, GMI values, and other CGM metrics for each sampling period.

Results:

The young child-specific GMI formula and the published GMI formula did not evidence significant differences when using 21-27 days of CGM data. The young child-specific GMI formula demonstrated higher correlations to laboratory HbA1c when using 18 or fewer days of CGM data. Overall, the GMI estimate and HbA1c values demonstrate a strong relationship in young children with T1D.

Conclusions:

Future research studies may consider utilizing the young child-specific GMI formula if the data collection period for CGM values is under 18 days. Further, researchers and clinicians may consider changing the default number of days of data used to calculate glycemic metrics in order to maximize validity of CGM-derived metrics.
Multisystem Inflammatory Syndrome in Children and COVID-19 Infections
Authors: Bultas Margaret W. , Fuller Kelli
Published: June 2021

The arrival of SARS-Co-V-2 (severe acute respiratory syndrome coronavirus 2) has brought not only the COVID-19 (coronavirus disease 2019) pandemic but also the development of a cluster of symptoms known as multisystem inflammatory syndrome in children (MIS-C). Information regarding the long-term implications of COVID-19 infections in children, as well as MIS-C, is scarce and is emerging on an almost daily basis. The purpose of this article is to provide an overview of the recent literature regarding COVID-19 and MIS-C, a Kawasaki-like inflammatory syndrome that developed in children around the same time the COVID-19 pandemic began. Because the school nurse monitors children across a variety of developmental domains, they are in a unique position to identify changes and notice long-term trends related to the health and development of children who contract both COVID-19 and MIS-C.

Posting preprints online allows psychological scientists to get feedback, speed dissemination, and ensure public access to their work. This guide is designed to help psychological scientists post preprints and manage them across the publication pipeline. We review terminology, provide a historical and legal overview of preprints, and give guidance on posting and managing preprints before, during, or after the peer-review process to achieve different aims (e.g., get feedback, speed dissemination, achieve open access). We offer concrete recommendations to authors, such as post preprints that are complete and carefully proofread; post preprints in a dedicated preprint server that assigns DOIs, provides editable metadata, is indexed by GoogleScholar, supports review and endorsements, and supports version control; include a draft date and information about the paper’s status on the cover page; license preprints with CC BY licenses that permit public use with attribution; and keep preprints up to date after major revisions. Although our focus is on preprints (unpublished versions of a work), we also offer information relevant to postprints (author-formatted, post-peer-review versions of a work) and work that will not otherwise be published (e.g., theses and dissertations).
