Abstract
Purpose
Patients with lung cancer experience a variety of distressing symptoms which could adversely quality of life. The aim of this study was to determine whether psychological distress prior to surgery is associated with health status and symptom burden in lung cancer survivors.
Methods
A longitudinal observational study with one-year follow‐up was carried out. Health status was measured by the WHO Disability Assessment Scale (WHO-DAS 2.0), the Euroqol-5 dimensions (EQ-5D) and the Pittsburgh Sleep Quality Index (PSQI). Symptoms severity included dyspnoea (Multidimensional Profile of Dyspnoea); pain (Brief Pain Inventory); fatigue (Fatigue Severity Scale) and cough (Leicester Cough Questionnaire).
Results
174 lung cancer patients were included. Patients in the group with psychological distress presented a worse self-perceived health status, functionality and sleep quality. The group with psychological distress also presented higher dyspnea, fatigue and pain.
Conclusion
Patients with psychological distress prior surgery present a greater symptom burden and a poorer self-perceived health status, lower functionality and sleep quality, than patients without distress one year after the lung resection.

Abstract
Background: The aim of this article is to develop a metamodel using a simulation-based approach to analyze the performance of the Patients’ Queue system of the emergency department. Methods: In this study, the variables affecting on resource efficiency were identified and analyzed using inferential statistics and then one-way ANOVA to estimate the effects of effective factors. Furthermore, the ED performance was simulated using Visual Paradigm software. Then, the results obtained from the implementation of the simulation model were considered as the input of the experimental design. Results: The findings indicate that the non-linear regression model could predict the length of the queue. Also, this model, according to acceptable parameters, can be used to predict the dependent variable. Conclusion: Therefore, the minimum value of queue length based on the developed model is obtained when the minimum length of the queue is obtained when the number of ED secretaries is at a high level and the number of paramedics and nurses is at a low level.

Published: June 2021

Abstract
The wheel re-profiling is an important part of railway wheelset maintenance. Researchers and railway operators have been very concerned about how to minimize the loss of time during wheel re-profiling without decreasing safety. Avoiding wheelset disassembly means considerable time savings, while reducing wheel damage during operation. Underfloor wheel lathes are the most appropriate tool to achieve this double objective, and therefore the most used nowadays.Multi-cut tool lathes have the disadvantage of being extremely expensive. On the other hand, with single tool lathes, re-profiling is not smooth or safe enough when current convex profile support rollers are used.In this article, a methodology to optimize the profile of the support rollers used in underfloor single tool lathes for railway wheel re-profiling is proposed. This novel profile design will minimize damage and increase the safety of such lathes, since it proposes a greater smoothness in the process. Simulations of re-profiling process have been carried out by the finite element method showing that the designed roller profile reduces drastically the impact/damage during the operation. Profile-optimized support rollers have been used in a real underfloor wheel lathe, showing good results.

Abstract
The fault diagnosis of gearbox and bearing in wind turbine is crucial to improve service life and reduce maintenance cost. This paper proposes a novel fault diagnosis method based on refined generalized composite multi-scale state joint entropy (RGCMSJE), robust spectral learning framework for unsupervised feature selection (RSFS) and extreme learning machine (ELM) to identify the different health conditions of gearboxes, including feature extraction, feature reduction and pattern recognition. In this method, MAED is firstly adopted to assist RGCMSJE in parameter selection. Second, RGCMSJE is utilized to extract the multi-scale features of gearbox vibration signal and construct high-dimension feature set. Thirdly, RSFS method is used to reduce the dimension of high-dimensional RGCMSJE feature set. In the end, the obtained low-dimensional features are input to the ELM classifier to realize fault pattern recognition. Through two gearbox fault diagnosis experiments, the effectiveness of the fault diagnosis method is verified. The analysis results show that this method can effectively and accurately identify different fault types of wind turbine gearbox.

Abstract
Potassium (K) deficiency affects physiological performance and decreasing vegetative growth in common bean plants. However, silicon (Si) supplied via nutrient solution or foliar application may relieve nutritional stress. Thus, two experiments were carried out: initially, a test was performed to determine the best source and concentration of leaf-applied Si. Subsequently, the chosen Si source was applied via nutrient solution or via leaf to verify if it is efficient in alleviating the effects caused by K deficiency. To that end, a completely randomized 2 x 3 factorial design was used, with two levels of K: deficient (0.2 mmol L− 1 of K) and sufficient (6 mmol L− 1 of K); and Si: via nutrient solution (2 mmol L− 1 of Si) or foliar spray (5.4 mmol L− 1 of Si) and control (0 mmol L− 1 of Si). In the first experiment, foliar spraying with sodium silicate and stabilized potassium at a concentration of 5.4 mmol L− 1 was better in favoring the physiology of bean plants. In the second experiment, K deficiency without the addition of Si compromised the plant's growth. Si applied through nutrient solution or foliar spray relieved K deficiency stress, increasing chlorophylls and carotenoids content, photosynthetic activity, water use efficiency and vegetative growth.

Abstract
Background

The aim of the present study was to clarify the evolution of the fetal heart rate (FHR) patterns in infants with cerebral palsy (CP) according to each type of umbilical cord trouble.
Methods

A case-control study was attempted in the subjects born from 2009 to 2014 and those with a birth weight of > 2000 g, gestational age of > 33 weeks, and disability due to CP, CP associated with (126 cases) and without (594 controls) umbilical cord troubles were compared.
Results

Therty-two were umbilical cord prolapse and 94 were other umbilical cord troubles coexisting antenatally. Abnormal FHR patterns had already been identified on admission in 13% of cases with umbilical cord prolapse and 40% of cases with cord trouble coexisting antenatally. A persistent non-reassuring pattern was significantly frequent in cases with cord trouble coexisting antenatally (p = 0.012) and less frequent in cases with umbilical cord prolapse (p = 0.003). Reactive-PD was significantly identified in 69% of the cases with umbilical cord prolapse and 35% of the cases with cord trouble coexisting antenatally, especially in the first stage of labor (p < 0.001).
Conclusion

Persistent non-reassuring patterns on admission and reactive-PD pattern during the 1st stage of labor were characterized in infants with CP related to umbilical cord troubles coexisting antenatally.

Published: June 2021

Abstract
Arsenic (As) is a quintessential toxic metalloid and it has been classified as Group 1 human carcinogen. The evolution of arsenic defense mechanisms due to the omnipresent nature of arsenic has resulted in its alteration to less toxic forms. The present study deals with the isolation of arsenic remediating microbial strains from soil samples and their integration into bioremediation strategy. From the metal contaminated site, 118 different bacterial strains were isolated from heavy metal contaminated site. Twenty-five strains were tolerant to arsenic and one bacterial strain Enterobacter cloacae (RSC3) demonstrated maximum growth at high concentration of arsenate (6000ppm). The cell growth kinetics of RSC3revealed the specific growth rate (µ) to be 0.55 h-1. The The bacteria hosts arsC gene in the genome involved in the reduction of arsenate to arsenite. AAS, SEM, TEM and EDX studies confirmed the arsenate transportation and efflux of arsenic by the bacteria. Furthermore, the strain showed multi-resistance to other heavy metals like zinc, cadmium, selenium and nickel and several antibiotics indicating its application for facilitating bioremediation of toxic metal contaminated sites.

Published: June 2021

Abstract
Background: Operational processes in lead mines cause workers to be occupationally exposed to lead particles, chronic exposure to lead can results innumerous health effects.Method: To know the effects of chronic lead exposure on liver function, the blood lead levels (BLL) and liver function tests of lead miners for 3- years (2017-2019) were followed and the obtained results were compared with those attained in the non-exposed group.Results: The BLL levels of the lead-mine workers were higher than with recommended level and the non-exposed group (24.15 and 6.35 µg dL-1, respectively, p<0.001). The findings indicated a positive and significant relationship between BLL and lactate dehydrogenase (r: 0.942, p<0.001), aspartate transaminase (r: 0.869, p<0.001), alkaline phosphatase (r: 0.9679, p<0.005), alanine transaminase (r: 0.9779, p<0.001), and bilirubin (r: 0.9169, p<0.001) levels, while we found a negative and significant correlation between BLL and triglyceride (r: -0.929, p<0.05), total protein (r: -0.896, p<0.001), albumin (r: -0.941, p<0.0021), and globulin (r: -0.863, p<0.001) levels. Moreover, no significant relationship was found between BLL and cholesterol, LDL, LDH, and BUN levels (p>0.05).Conclusions: This report showed that the chronic lead exposure is a major occupational hazard in lead mine workers. Despite the fact that the level of liver function parameters was in the normal range, the results of 3- years follow-up show a significant relationship between BLL and alteration of liver function parameters levels of lead miners. The study can be helpful in raising awareness of alteration in liver functions due to occupational exposure to lead.

Abstract
To investigate the changes of the respiratory infectious diseases (RID) and air quality during the COVID-19 outbreak over Yangtze River Delta Region, China. We investigate the impact of COVID-19 control measures on changes of RID and air quality by constructing two proportional test and fitting ARIMA and piecewise regression models. A total of 81,345 and 1,048,511 cases of RID were identified in Shanghai and Zhejiang Province, respectively. The incidence of seven RID and influenza decreased by 37.80% and 49.57% in 2020 in Shanghai and decreased by 20.39% and 43.40% in Zhejiang Province, respectively. The monthly concentrations of overall air pollutants decreased by 12.7% and 12.85% in 2020 Shanghai and Zhejiang compared to the 2017–2019 period; the most rapid decrease was observed in SO2 concentrations (32.39% and 33.37% in Shanghai Province and Zhejiang Province, respectively). A moderate correlation was seen between influenza incidence and monthly SO2 concentrations in Shanghai (r = 0.59). A 10 μg/m3 decrease of SO2 was significantly associated with the reduction of influenza incidence(2907.76 per 100,000). This study provided the additional evidences that the measures taken for COVID-19 were effective in improving the air quality and reducing spread of other common respiratory diseases, but direct causality is not established.
Detecting Nonclassicality and Non-gaussianity by the Wigner Function and Quantum Teleportation in Photon-added-and-subtracted Two Modes Pair Coherent State
Authors: Truong Minh Duc , Ho Chuong Sy , Tran Dat Quang 
Published: June 2021

Abstract
We introduce a new state called photon-added-and-subtracted two modes pair coherent state (PAASTMPCS) by simultaneously adding and subtracting photons to the different modes of a pair coherent state. Its nonclassical and non-Gaussian properties are strengthened via the negative values of its Wigner function as the numbers of adding and subtracting photons are increased. It indicates that the PAASTMPCS is an entangled state. When increasing the numbers of photon-added and photon-subtracted to a pair coherent state, the degree of entanglement in the PAASTMPCS is enhanced compared with the original pair coherent state. By using a PAASTMPCS as a non-Gaussian entangled resource, the quantum teleportation processes are studied in detail. It is shown that the number sum and phase difference measurements protocol is more appropriate than the orthogonal quadrature components measurements protocol in the quantum teleportation process of a coherent state.

Published: June 2021

Abstract
The demand for an alternative source of energy, the challenge of increase in waste and pollution initiates the need for renewable energy and management of waste using anaerobic digestion (AD). AD is an effective and efficient method of waste treatment and energy generation. Certain operational parameters influence the anaerobic degradation of waste to energy. The impact of physicochemical parameters in anaerobic digestion was conducted using chicken wastes and food wastes as organic substrate under semi-continuous conditions at hydraulic retention time (HRT) of forty-two (42) days in a fifteen (15) litre fabricated digesters labeled D1, D2 and D3 at mesophilic temperature. The pH, volatile solid, percentage moisture, total ammonia, total solid, volatile fatty acid, alkalinity was assessed. The results indicated a pH value of 6.65 ± 0.12, 7.27 ± 0.13, 6.43 ± 0.27, volatile fatty acid of 72.17 ± 1.42, 58.35 ± 2.58, 40.56 ± 0.38, and moisture content of 98.9 ± 2.65, 92.3 ± 1.81, 96.4 ± 3.60 for D1 (Chicken waste and food wastes), D2 (Chicken wastes+), D3 (control) respectively. A collective biogas yield of 686±17.00 kpa for D1, 700±11.00kpa for D2 and 521±21.00 kpa for D3 were recorded. The characterization of biogas analyzed with non-dispersive infrared (NDIR) gas analyzer (gas board 3100p) revealed a percentage methane content of 46.11±1.11%, 52.4±1.05 %, 50.31±1.33 % for D1, D2 and D3 respectively The study shows that physicochemical properties are useful tools to indicate digester failure/stability and also to enhance anaerobic digestion process.

Published: June 2021

Abstract
Background

Gestational diabetes mellitus is a frequent complication of pregnancy, affecting the health of mothers and their offspring. The new diagnostic strategy for GDM, proposed by IADPSG in 2010 and WHO in 2013, raised hope for a reduction in perinatal complications. The purpose of the study was to evaluate factors influencing obstetric results in a group of women diagnosed with diabetes, regardless of the adopted diagnostic criteria, compared to a group of pregnant women in whom GDM was excluded.
Methods

It was a retrospective study based on the analysis of births given after 37 weeks of pregnancy at the 2nd Department of Obstetrics and Gynaecology, Warsaw Medical University during the period from 2013 to 2015. All pregnant women had a 75g OGTT between the 24th and 28th weeks of pregnancy. The study compared risk factors for obstetric complications for patients with gestational diabetes to a group of women without GDM. The impact was analysed of the aforementioned factors on maternal and paediatric obstetric outcomes.
Results

The parameters significantly influencing the risk of composite adverse maternal outcomes were the circumference of the pregnant woman’s abdomen [OR: 1.08 (1.04; 1.11)] and multiparity, which reduced the risk of this complication by almost half [OR: 0.47 (0.30; 0.75). The size of the maternal abdominal circumference before delivery was a strong factor correlating with the occurrence of perinatal complications in both the mother and the foetus in the entire examined cohort. A circumference over 100 cm increased the risk of at least one pregnancy complication (increased blood loss, soft tissue injuries, pre-eclampsia) by almost 40% (OR 1.38, p < 0.001).
Conclusions

Apart from normalization of glycaemia, stabilization of the percentage of adipose tissue and non-glycaemic obstetric risk factors may be necessary to obtain further improvement in obstetric outcomes in this pregnant population.
Light Rail Transit System Energy Flow Analysis for the Case of Addis Ababa City: For the Application of Regenerative Energy and Energy Storage
Authors: Kebede Asegid , Worku Getachew Biru 
Published: June 2021

Abstract
Significant amounts of energy can be saved by installing energy storage on an electrified transit system allowing energy from braking to be captured. The amount of energy saved is dependent on the amount of energy transferred during braking which relies on the drive cycle and the vehicle parameters. Additional energy is saved through a lower overall energy requirement of train, which results in a reduction in traction supply losses. The overall benefit can be determined by analyzing the energy flow through components in an electrified transit system and hence determining the change in energy dissipations when energy storage is installed. In this paper, electrified transit system energy flows are analyzed for the implementation of energy storage system on board on Addis Ababa light rail transit. The methodology used assesses energy flows in the traction system, establishing where energy is dissipated. The analysis is performed for a specified drive cycle. Finally, the analysis showed that 36 % of traction energy could be saved through the implementation of energy storage on the Addis Ababa light rail transit.
Nonreciprocal and Directional Wave Propagation in a Two-Dimensional Lattice With Bilinear Properties
Authors: Lu Zhaocheng , Norris Andrew 
Published: June 2021

Abstract
A passive method of realizing nonreciprocal wave propagation in a two-dimensional (2D) lattice is proposed, using bilinear springs combined with the necessary spatial asymmetry to provide a stable and strong departure from reciprocity. The bilinear property is unique among nonlinear mechanisms in that it is independent of amplitude but sensitive to the sign of the wave motion; the 2D setup allows the flexibility of generating spatial asymmetry at both small and large scales. The starting point is a linear 2D monatomic spring-mass lattice with strong directionally dependent wave propagation. The source and receiver are aligned so that there is virtually no direct wave transmission between them. Adding a region of bilinearity combined with spatial asymmetry that is not in the direct path between the source and receiver causes signal transmission via nonreciprocal scattering. A variety of spatially asymmetric bilinear configurations are considered, ranging from compact modulations confined within the unit cell to extended ones over the whole section, to obtain different dynamic nonreciprocal effects. Simulations illustrate how the combination of bilinearity and spatial asymmetry ensures a passive amplitude-independent nonreciprocal 2D system for a variety of different excitations.

Abstract
Forage Sorghum (Sorghum bicolor (L.) Moench) is an annual gramineous forage, which is a high-quality C4 crop. It is widely planted with Forage Maize in the world, especially in the developed countries of animal husbandry. Many of its important physiological characteristics vary with germplasm and growth environment. Acid detergent fiber is a kind of carbohydrate insoluble in acid detergent in plant material or feed containing plant material, including pure cellulose and acid cellulose. Acid detergent fiber widely exists in the stem and leaf tissues of forage sorghum, which is the main substance affecting the digestibility of livestock. It has a very important impact on the milk yield and quality of cows, dairy sheeps and pigs. In order to further understand its genetic mechanism, we re-sequenced 206 Forage Sorghum Germplasms from different regions of the world and identified 14,570,430 SNPs and 1,967,033 indels. Based on SNP markers, we analyzed the population genetic structure and identified the gene loci related to acid detergent fiber content by genome-wide association analysis (GWAS). Genetic relationship between materials showed that Asian and American sorghum varieties, breeding lines and improved varieties were more diverse, while European varieties were relatively more closely related. These findings provide new clues and directions for further study. Eight QTLs harboring 91 genes were found to be associated with acid detergent fiber content. These genes were significantly enriched into 6 major genes involved in cell membrane material transport or enzymes, showing a regional distribution. This finding provides a basis for us to understand the origin and spread of haplotypes related to acid detergent fiber content, which would accelerate the study of genetic gain of acid detergent fiber content, and help breeders improve feed quality and stress tolerance of forage sorghum.
