Published: January 2021

AbstractAdvances made in pediatric cardiology, cardiac surgery and critical care have significantly improved the survival rate of patients with congenital heart disease (CHD) leading to an increase in children with CHD presenting for noncardiac surgical procedures. This study aims (1) to describe the trend and perioperative mortality rates in patients with CHD undergoing noncardiac surgical procedures at children’s hospitals over the past 5 years and (2) to describe the patient characteristics and the most common type of surgical procedures. The Pediatric Health Information System (PHIS) is an administrative database that contains inpatient, observation, and outpatient surgical data from 52 freestanding children’s hospitals. Thirty-nine of the 52 hospitals submitted data on all types of patient encounters for the duration of the study from 2015 to 2019. The total numbers of non-cardiac surgical encounters among patients with history of a CHD diagnosis significantly increased each year from 38,272 in 2015 to 45,993 in 2019 (P < 0.001). Despite the increase in case numbers, there has been a significant decline in mortality rates to the most recent incidence of 1.06% in 2019. Careful patient selection and medical optimization of patients aligned with specific expertise at dedicated children’s hospitals may lead to improvement in mortality rate. Future studies comparing the outcomes of patients with cardiac disease based on hospital type and volume as well as type of providers may help determine the future of care including potential need for regionalization of noncardiac care for this vulnerable patient population.

AbstractKnowledge about the fitness cost imposed by herbicide resistance in weeds is instrumental in devising integrated management methods. The present study investigated the germination response of ACCase-resistant (R) and susceptible (S) winter wild oat under different environmental conditions. The DNA of the plants was sequenced after being extracted and purified. The segregated F2 seeds were subjected to various temperatures, water potentials, NaCl concentrations, different pHs, darkness conditions, and burial depths. The results of the sequencing indicated that Ile-2041-Asn mutation is responsible for the evolution of resistance in the studied winter wild oat plants. The seeds were able to germinate over a wide range of temperatures, osmotic potentials, NaCl concentrations, and pHs. Germination percentage of R and S seeds under dark and light conditions was similar and ranged from 86.3 to 88.3%. The highest emergence percentage for both R and S plants was obtained in 0, 1, and 2 cm depths and ranged from 66.6 to 70.3%. In overall, no differences were observed in the germination response between the R and S winter wild oat plants under all studied conditions. No fitness cost at seed level indicates that control of R winter wild oats is more difficult, and it is essential to adopt crop and herbicide rotation to delay the further evolution of resistance.
Plasma flows and sound-speed perturbations in the average supergranule
Authors: Korda David , Švanda Michal 
Published: January 2021

Context. Supergranules create a peak in the spatial spectrum of photospheric velocity features. Even though they have some properties of convection cells, their origin is still being debated in the literature. The time–distance helioseismology constitutes a method that is suitable for investigating the deep structure of supergranules.
Aims. Our aim is to construct the model of the flows in the average supergranular cell using fully consistent time–distance inverse methodology.
Methods. We used the Multi-Channel Subtractive Optimally Localised Averaging inversion method with regularisation of the cross-talk. We combined the difference and the mean travel-time averaging geometries. We applied this methodology to travel-time maps averaged over more than 104 individual supergranular cells. These cells were detected automatically in travel-time maps computed for 64 quiet days around the disc centre. The ensemble averaging method allows us to significantly improve the signal-to-noise ratio and to obtain a clear picture of the flows in the average supergranule.
Results. We found near-surface divergent horizontal flows which quickly and monotonously weakened with depth; they became particularly weak at the depth of about 7 Mm, where they even apparently switched sign. The amplitude of the ‘reversed’ flow was comparable to the background flows. The inverted vertical flows and sound-speed perturbations were spoiled by unknown systematic errors. To learn about the vertical component, we integrated the continuity equation from the surface. The derived estimates of the vertical flow depicted a sub-surface increase from about 5 m s−1 at the surface to about 35 m s−1 at the depth of about 3 Mm followed by a monotonous decrease to greater depths. The vertical flow remained positive (an upflow) and became indistinguishable from the background at the depth of about 15 Mm. We further detected a systematic flow in the longitudinal direction. The course of this systematic flow with depth agrees well with the model of the solar rotation in the sub-surface layers.

ABSTRACTThe purpose of the present study was to examine how coaches’ satisfaction with the team could be related to their reported interpersonal style towards young athletes, and to analyze the mediating role of basic psychological needs (i.e. need satisfaction and need frustration) in this relationship. Participants were 352 coaches (16–67 years old; M age = 32.88, SD = 11.14) from 48 clubs, who had between 1 and 52 years of training experience (M = 23.23, SD = 15.02). Structural equation modelling (SEM) was employed to test the relationships between variables. Results showed that satisfaction with the team is positively related to coaches’ need satisfaction, and negatively to their need frustration. Need satisfaction positively predicted coaches’ need‐supportive style, and need frustration predicted their need‐thwarting style. Regarding indirect effects, need satisfaction positively mediated the relationship between coaches’ satisfaction with the team and their need‐supportive style, and need frustration negatively mediated the relationship between coaches’ satisfaction with the team and their need‐thwarting style. These findings are a first step to highlight satisfaction with the team as an antecedent of coaches’ self‐reported need‐supportive and need‐thwarting behaviours towards athletes, and the mediating role of coaches’ psychological needs (need satisfaction and need frustration) in this relationship.Highlights

ABSTRACTIn sports, outperforming your peers at young age does not guarantee a professional sports career as an adult. To gain more insight in how performance in youth cycling competitions can be an indicator for future success, the current study (a) examined differences in success rate between future achievers and future non‐achievers, (b) investigated whether the relative age effect affects these career pathways and (c) explored to what extent youth competitive performance can predict success at adult age. The sample consisted of 307 male road cyclists who achieved at least one top 10 result during national and provincial youth competitions (U15, U17, U19). Thirty‐two were classified as future achievers because they reached senior elite level; the remaining 275 were classed as future non‐achievers. Non‐parametric analyses of longitudinal data, Kruskal–Wallis and logistic regressions were applied. These analyses revealed that the future achievers started to outperform the future non‐achievers from U17 onwards. While the relatively older cyclists have an advantage over other cyclists in U15, this effect was smaller in U17 and was absent in U19. Finally, the competitive success rate of U15 cyclists could not predict success at adult age. However, for U17 and U19 cyclists each additional top 10 result was associated with 3–5%, and 6% higher chance to reach elite level at adult age, respectively. Overall, these results demonstrate that estimating potential based on competition results is unpredictable in the U15 category, however, may provide a better indication of future success from U17 onwards.Highlights
The competitive success rate of U15 cyclists could not predict success at adult age
From the U17 category onwards, future achievers had higher success rates, and success rate has some predictive value for performance at senior elite level.
Competitive performance is influenced by relative age effect in the U15 category, however, this effect disappeared as the athlete progressed into older age categories.
Future non‐achievers experience a significant decrease in success rate when transitioning to a new competition category.

Abstract
The purpose of this study is to determine whether the flipped learning method via MOODLE can improve learning outcomes and motivation to learn discrete mathematics during COVID-19 pandemic. This is because discrete mathematics is one of the mathematics subjects that requires a lot of practice and needs direct direction by lecturers or educators. In this study, we used Classroom Action Research that consisted of two cycles. The stages in each cycle were plan, implementation, observation, and reflection. Based on the results of the study, it was found that the flipped learning method via MOODLE can improve the learning outcomes of discrete mathematics from only 30% of students who complete to 100% of students completed. In addition, students’ discrete mathematics learning motivation increased from 45% or medium criteria to 79% or high criteria. The stages that can be used are (1) lecturers provide stimulus through questions to students to find references independently of a question, (2) students learn the material independently and make questions about the material which is not yet understood, (3) students and lecturers conduct discussions to correct misconceptions, and (4) students work on questions from lecturers as evaluation.
On Energy Transmission to Remote Location Using a Repeater

Published: January 2021

Abstract
This paper discusses a power supply system to operate a small-scale monitoring system where the sun does not reach and power supply is difficult. When we try to operate a small monitoring system in a place where power supply is difficult, how to secure power is important. We consider a system that transmits light energy from the ground to the ground using a floating repeater. It is assumed that both the position and the angle of the receiver are fixed. It is also assumed that the repeater is affected by the disturbance. We aim to control the light to reach the receiver under any circumstances. Some experiments were conducted to verify whether we could perform the assume control by developing a system based on the proposed method on a small scale. As a result, it was confirmed that roughly assumed control could be performed.

Abstract
With the drastic reduction of China's land and shallow sea oil and natural gas resources, offshore oil and gas field exploration has gradually developed into the deep sea of 1500-300 m. Traditional steel materials are no longer applicable, and fibre composite materials have become the most exploited in subsea oilfields. One of the good materials is widely used in all aspects of deep-sea oil field equipment, providing a reliable guarantee for the development of deep-sea oil and gas fields. Based on this research background, the paper discusses the characteristics of carbon fibre composite materials (light weight, high specific strength, high specific modulus, fatigue resistance, corrosion resistance, and small thermal expansion coefficient), and discusses its application in the field of subsea oilfields.

Abstract
Partial discharge type identification is of great significance to the diagnosis of insulation faults in high-voltage power equipment. The partial discharge type recognition method based on deep learning map diagnosis has the disadvantages of large memory space and high hardware environment requirements. This paper presents a GIS discharge defect diagnosis system and method based on Extreme Learning Machine (ELM), which can be deployed on the edge layer equipment. The principal component analysis method is used to obtain the principal parameters that characterize the defects and form a sample feature data set. The sample feature data set is used to train the neural network model and continuously optimize it. Finally, the trained neural network model is used to identify the types of partial discharge defects. This method can effectively solve the problems that the partial discharge type identification method based on atlas diagnosis occupies large memory space and requires high hardware environment, which is convenient for the wide application of engineering.

The voltage sharing control strategy based on sorting algorithm is widely used in modular multilevel converter Converter (MMC) in practical engineering, aiming at the problems of frequent switching states, high switching frequency and large loss caused by traditional scheduling algorithm, a voltage sharing control strategy based on optimal sequencing is proposed by introducing the average value of capacitor voltage and the maximum deviation threshold under the premise of considering the switching state of sub modules at the last moment. Finally, the simulation system of modular multilevel converter is built in PSCAD / EMTDC for verification. The simulation results show that the proposed optimal sequence voltage sharing control strategy significantly reduces the switching frequency of the devices and improves the operation performance of the system.

Authors: Qiu Xiaohong , Ye Zhiwei 
Published: January 2021

Abstract
To solve the problem of low classification and recognition rate caused by small number of fault samples and inaccurate feature extraction in analog circuit fault diagnosis, a fault diagnosis algorithm for analog circuit system based on the combination of wavelet packet energy entropy and Deep Belief Network (DBN) is proposed. Firstly, the original output voltage signal of the circuit is decomposed by a multi-layer wavelet packet, then the feature vector is constructed in the form of energy entropy, and then the principal component analysis (PCA) is used for feature selection. The reduced dimension feature vector is taken as the input vector of DBN, and the fault diagnosis is completed after training and learning of the DBN network model. The experimental results show that compared with other algorithms, the proposed method can be more accurate and effective in diagnosing fault types in analog circuits, especially for Sallen-Key band-pass filter circuits, the fault recognition rate reaches 100%.
