Abstract
Measuring species richness of tropical forests is a major challenge. Such measurement is a key information in many senses, from an evolutionary perspective to conservation of threatened, fragile habitats. Data has gradually shown that the canopy of tropical forest is a hugely complex component of the forest, but a precise assessment of the diversity of megadiverse groups in the canopy is still wanting. We collected large samples of insects were along a period of two weeks using 6-meter Gressitt-style Malaise traps set at five heights on a metal tower in a tropical forest north of Manaus—one trap at the ground level, one trap above the canopy (32 m) and three traps at intermediate levels (8, 16 and 24 m). The samples contained 37,778 specimens belonging to 18 order of insects. Fifty-seven families of flies (Diptera) were found, 39 of which were identified to 368 genera and 856 species. The species of these 39 families of flies fit into eight patterns of vertical distribution of abundance and species richness of the fauna, with patterns of one or two peaks of species at different levels. A total of 527 (61.6%) of the 856 fly species recognized in the samples were not collected at the ground level. The canopy-associated species of Diptera showed a high species richness and a relatively low abundance indicating that they represent vulnerable components of tropical diversity. The biology of the flies families and genera we collected in the canopy suggest that the evolution of flies went through a unique process: independent clades of Diptera explored in different ways the resources originated along the very evolution of the angiosperm forest canopy along the early Cenozoic. Unlike other primarily phytophagous groups of insects, flies radiated into a large array of biologies associated with the canopies: parasitoids, hematophagous, phytosaprophagous, kleptoparasites, sap feeders, gall-makers etc. The results only stress the need of additional strategies to protect this diversity.

Abstract
Increasing of humanity and development of Internet resources, storage size is growing with each day, whereby digital records are accessible in clouds of an exploratory format. The immediate future of Big Data is coming shortly for almost all other sectors. Big data can aid in the metamorphosis of significant company operations by offering a recommended and reliable overview of available data. Big data has also figured prominently in the detection of violence. Present framework for designing Big data implementations is capable of processing vast quantities of data through Big data analytics using collections of computing devices together to execute complex processing. Furthermore, existing technologies have not been built to fulfil the specifications of time-critical application areas and are far more oriented on real applications than on time-critical ones. This paper proposes the lightweight architecture called Yet Another Resource Negotiator (YARN), which focuses on the concept of a time-critical big-data system from the perspective of specifications and analyses the essential principles of several common big-data implementations. YARN as the normal computational framework to help MapReduce and another application instances within that Hadoop cluster. YARN requires multiple programs to execute concurrently on a constitutive common server and assent programs to delegate services depending on need. The final evaluation is accompanied by problems stemming from infrastructure and services that serve applications, recommend frameworkand provide preliminary efficiency behaviours that often contribute system impacts to implementation reliability.

Abstract
In this study, hematite graphene oxide (αFe2O3-GO) powder nanocomposites and thin-film hematite graphene oxide (αFe2O3-GO) were synthesized for application in the removal of Rhodamine B (RhB) from textile wastewater. αFe2O3-GO nanomaterials were placed onto the FTO substrate to form a thin layer of nanocomposites. Different analysis including XRD, FTIR, Raman spectra, XPS, and FESEM were done to analyze the morphology, structure, and properties of the synthesized composites as well as the chemical interactions of αFe2O3 with GO. The photocatalytic performance of two synthesized composites was compared with different concentrations of αFe2O3-GO. The results showed that powder nanocomposites are more effective than thin-film composites for the removal of RhB dye. αFe2O3-GO-5% powder nanocomposites removed over 64 % of dye while thin-film nanocomposites had less removal efficiencies with just under 47 % removal rate. The reusability test was done for both materials in which αFe2O3-GO-5 % powder nanocomposites removed a higher rate of dye (up to 63 %) in more cycles (6 cycles).

Published: April 2021

Abstract
Different concentrations of nickel oxide (NiO) nanoparticles were successfully inserted into polystyrene (PS) polymer matrix using the solution casting method. X-ray diffraction (XRD), Fourier transform infrared (FT-IR), high-resolution scanning electron microscope (SEM), and UV-Vis techniques are used to characterize the nanocomposites. XRD, SEM, and FT-IR results indicate that PS and NiO nanoparticles have a good interaction and a high degree of complexity. Using UV–Vis technique, the absorbance of nanocomposites is improved by increasing the nanofiller content. Both the Urbach energy (EU) and the optical energy gap (Eg) were calculated using the Urbach relation and the Tauc model. Refractive indices values of nanocomposites display raising trend with NiO content which promote PS/NiO nanocomposites for use in photonic applications and designing optical devices. Nanocomposites' electrical conductivity was also investigated. The electrical conductivity of the nanocomposites has increased significantly due to the uniform dispersion of NiO nanoparticles and by increasing its content. Conduction is achieved by correlated barrier hopping (CBH).
Psychometric Properties and Factor Structure of the Personality Inventory for DSM-5–Brief Form (PID-5-BF) in Iranian Student and Clinical Samples
Authors: Athar Mojtaba Elhami , Ebrahimi Ali 
Published: April 2021

Abstract
Background

The Personality Inventory for DSM–5, Brief Form (PID-5-BF) was developed to assess the DSM-5's alternative trait model for diagnosing personality disorders. Psychometric properties of PID-5-BF have been verified in some Western countries, but to our knowledge, no study has examined the psychometrics of PID-5-BF in Iranian settings. This is the first study designed to examine the factor structure, internal consistency, and convergent/discriminate validity of the Persian PID-5-BF with student and clinical samples in Iran.
Methods

378 university students (n = 378; M-age = 16.35; 55.6 % females) and 150 clinical patients (n = 150; M-age = 43.81; 58.7 % men) completed the Persian version of the PID-5-BF and NEO-FFI. Confirmatory factor analyses (CFAs) were performed to examine the five-factor model of PID-5-BF. Also, internal consistency and external validity of PID-5-BF were calculated.
Results

Confirmatory factor analysis supported the proposed five-factor model of PID-5-BF in both groups. The Chronbach's alpha coefficient ranged from .57 (Disinhibition) to .65 (Psychoticism) for the student sample and from .48 (Antagonism) to .67 (Detachment) for the clinical sample, while when relying on the MIC values, the PID-5-BF subscales indicated acceptable internal consistency in both groups. PID-BF-5 significantly differentiated the clinical sample from the student sample (p < .001), indicating the measure's adequate discriminate validity. Additionally, PID-5-BF subscales yielded hypothesized association with the external criterion variable in only the student sample.
Conclusion

Our results support the use of the PID-5-BF as a screening measure of dimensional maladaptive personality traits in Iranian samples. However, future studies are needed to examine the convergent validity of PID-5-BF in Iranian clinical samples with suitable external criterion measures.

Published: April 2021

Abstract
Precipitation is critical for maintaining ecosystem stability, especially in arid regions. This study was primarily focused on the changes during the present (i.e., from 1985 to 2005) and future (i.e., from 2040 to 2059) periods in Xinjiang, northwest China. To predict the future climate, the Weather Research and Forecasting model was run in Xinjiang using National Climate Research Center Community Climate System Model version 4 for the mid-21st century under representative concentration pathways 4.5 and 8.5 (RCP4.5 and RCP8.5, respectively). The results indicate that the amount of annual precipitation would increase in the future under RCP4.5 and RCP8.5 in Xinjiang, especially in the mountainous areas. The increase in precipitation was predicted to be much smaller under RCP8.5 than under RCP4.5, except in Southern Xinjiang. Moreover, the increased precipitation predicted in Xinjiang implies that the current humid and warm conditions will continue. In addition, the largest increase in seasonal precipitation was predicted to occur in spring and summer in Tianshan and Northern Xinjiang, whereas this phenomenon will occur in spring and winter in Southern Xinjiang. In addition, it was predicted that daily heavy precipitation events will occur more frequently in various subregions of Xinjiang, although light rain events will remain dominant. Finally, the increase in the frequency of heavy precipitation events was found to be related to the vertically integrated column precipitation, whereas the relative humidity was observed to be closely related to the changes in annual and seasonal precipitation.

Published: April 2021

Abstract
Coal mine water in China is mainly mine water containing suspended solids（SS）. The relationship between suspended solids and turbidity in mine water with different SS content gradients was studied and a model formula was established. Finally, the accuracy of the model formula is verified by the actual detection values of five kinds of mine water. Two conversion formulas for turbidity and suspended matter have been obtained in the study. When the suspended matter content is 0-200mg/L, the relationship curve between turbidity and SS is y=0.9336x-3.1393, R2=0.9986; When the suspended matter content is 200-600 mg/L, the relationship curve between turbidity and SS is y=0.5314x+94.421, R2=0.9905. Finally, the study has used the measured values of SS in other coal mines and the calculated values obtained from the formula to carry out error analysis. It is found that the error of the relationship between turbidity and SS with a suspended matter content of 0~200mg/L is controlled within 4%; the error of the relationship between turbidity and SS of mine water with a suspended matter content of 200~600mg/L is controlled within 5%. Considering the unavoidable error factors, it is considered that the model formula can be applied to the detection of suspended solids in actual mine water.

Published: April 2021

Abstract
Context:

Patients undergoing surgery for lung cancer experience a variety of symptoms such as pain and coughing, which interfere patients’ daily function after surgery. However, there may be some differences between the perception of symptoms by medical staff and the actual situation of patients.
Objectives

This study aimed to investigate patient’s experiences after lung cancer surgery and analyze whether the perception of postoperative symptoms by the medical staff differed from that reported by patients.
Methods

Semi-structured qualitative interviews concerning in-hospital experiences were conducted from June 2018 to October 2019 in 39 patients undergoing lung cancer surgery at the Sichuan Cancer Hospital. Moreover, 22 thoracic medical staff were instructed to answer open questions about their perception of symptoms related to the lung cancer surgery. Types and frequencies of symptoms from patients and medical staff were compared.
Results

Thirty-nine patients were interviewed, and 22 medical staff from the Department of Thoracic Surgery were investigated. The most frequent patient-reported symptoms were pain (967 times, 39 patients, 100%), coughing (904 times, 37 patients, 94.87%), shortness of breath (491 times, 35 patients, 89.74%), disturbed sleep (412 times, 34 patients, 87.18%), and interference with walking (347 times, 36 patients, 92.31%). Of the above symptoms, four were perceived by medical staff, whereas interference with walking was replaced by fatigue.
Conclusion

Although the medical staff and patients had a certain consensus on main symptoms, differences in perception still exist. Medical staff need to pay more attention to postoperative interference with walking.

Published: April 2021

Abstract
Introduction: Up-to-date monitoring of non-combustible nicotine products (NNP) is important to assess their impact. To date, there is little evidence on the association between long-term regular use (defined here as one-year or more) of NNP and current smoking status. Aims/methods: The purpose of this study was to examine the prevalence, and sociodemographic, alcohol and smoking status correlates, of ever regular use of NNP in England in 2020.A cross sectional survey of adults in England between February and June 2020. Results: 8,486 adults were surveyed, 94.9% (8,055) were complete cases. The weighted prevalence of ever regular NNP use was 5.4% (n=436; 95%CI 5.0-6.0), of which 82% (n=360; 95%CI 78.7-85.8) was single, and 18% (n=79; 95%CI 14.8-22) multiple product use. Amongst ever regular NNP users, the prevalence of ever regular nicotine replacement therapies (NRT), e-cigarette and heated tobacco product use was 64.7% (95% CI 60.1-69), 43.4% (95%CI 38.8-48) and 2.5% (95% CI 1.4-4.5), respectively. In regression analysis, ever regular NNP use was independently associated with smoking status, being significantly higher among current (22.3%; Adjusted OR (aOR) 34.9, 95%CI 24.0-50.8) and ex-smokers (12.7%, aOR 19.8, 95%CI 11.1-14.4) than among never smokers (0.6%). More advantaged occupational grade (aOR, 1.27 95% CI 1.02-1.57) and at least hazardous alcohol use (aOR, 1.38 95%CI 1.06-1.78) were independently associated with greater prevalence of ever regular NNP use.Conclusions: Ever regularly using NNP was highest among smokers and ex-smokers and rare among never smokers. Among people who have ever regularly used NNP, NRT is the most popular.

Abstract
Adaptive divergence would occur even between the insufficiently isolated populations when there is a great difference in the environments of their habitats. The individuals present in the intermediate zone of the two divergent populations are expected to have an admixed genetic structure due to gene flow. A selective pressure that acts on the genetically admixed individuals may limit the gene flow and promote the adaptive divergence. Here, we addressed a question whether the selection occurs in the genetically admixed individuals between the divergent populations and assessed its effects on the population divergence. We obtained the whole-genome sequences of a perennial montane plant, Arabidopsis halleri, which has clear phenotypic dimorphisms between altitudes, along an altitudinal gradient of 359–1,317 m with a high spatial resolution (mean altitudinal interval of 20 m). We found the zone where the highland and lowland genes were mixing. Using the FST approach, we found that 35 and 13 genes in the admixed zone had a high frequency of alleles that are accumulated in highland and lowland subpopulations, respectively, suggesting that these genes have been selected in the admixed zone. This selection might limit the gene flow and contribute to the adaptive divergence along the altitudes. In the single-nucleotide polymorphism (SNP)-based analysis, 3,000 out of 27,792 Altitude-Dependent SNPs had extremely high homozygosity in the admixed zone. In 84.7% of these SNPs, the frequency of homozygotes of highland alleles was comparable to that of lowland alleles, suggesting that these alleles are neutral but the heterozygotes were selectively eliminated. The distribution of highland and lowland alleles of these SNPs was not clearly separated between altitudes, implying that such selection did not impede the gene flow. We conclude that the selection occurring at the intermediate altitude affects the genetic structure in the admixed zone and adaptive divergence along the altitudes.

Abstract
When the manufacturing industry is dealing with information technology, it has to face a large number of parameters and frequent adjustments. How to correctly import and maintain it has always been a huge challenge. Once the setting is wrong, it will bring losses, ranging from poor products that require maintenance, heavy work or scrapping, and at worst, resulting in production line shutdown, reduced factory productivity, delayed shipments and other adverse consequences. In order to improve this problem, this study uses the data in the approval form of a customized label set by an electronic manufacturer and use artificial intelligence models to find out the hidden rules behind a large number of customized labels, through data processing and model building. Model and parameter experiments are used to improve the effectiveness of artificial intelligence models, and for the problem of time characteristics but uneven distribution of data, the method of cyclic testing is adopted to increase the diversity of the test set. The results of this paper, we integrate each stage and an auxiliary decision-making is established. When the user's setting is inconsistent with the predicted result, a warning will be displayed to speed up the operation process, reduce the scope of confirmation, and ultimately reduce the error rate, thereby improving the problem, reducing scrap and production line shutdown to improve factory productivity. In the statics, the accuracy rate of new recruits was only 80%. The accuracy rate of the artificial intelligence model can be increased to 95%. The number of stoppages is reduced from 4 times per month to 1 time per month. Under full capacity, this assistance the decision-making system can reduce loss cost.

Abstract
This study served as the pioneer in studying the anti-cancer role of chicken cathelicidin peptides. Chicken cathelicidins were used as anticancer agent against the breast cancer cell line (MCF-7) and human colon cancer cell line (HCT116). An in vivo investigation was also achieved to evaluate the role of chicken cathelicidin in Ehrlich ascites cell (EAC) suppression as a tumor model after subcutaneous implantation in mice. In addition, the mechanism of action of the interaction of cationic peptides with breast cancer cell line MCF-7 was also investigated. It was found during the study that exposure of cell lines to higher concentration of chicken cathelicidin for 72 h reduced cell lines growth rate by 90%-95%. These peptides demonstrated down-regulation of (cyclin A1 and cyclin D genes) which are essential for G1/S phase transient and S/G2 phase and consequently causes “prometaphase arrest” ultimately leading to death of MCF-7 cells. The study showed two- and three-times higher expression of the caspase-3, and − 7 genes respectively in MCF-7 cells treated with chicken peptides (especially cathelicidin-2 and − 3) relative to untreated cells which encouraged pro-apoptotic pathway, autophagy, and augmentation of the anti-proliferative activity. Our data showed that chicken ( CATH-1 ) enhance releasing of TNFα, INF-γ and upregulation of granzyme K in treated mice groups, in parallel, the tumor size and volume was reduced in the treated EAC-bearing groups after cathelicidin administration compared to untreated EAC-bearing group. Additionally, animals received high dose of cathelicidin-1 (40 µg/ml) displayed an apical survival rate compared to untreated carcinoma control and animals which received low dose of cathelicidin (10 and 20 µg/ml). Tumor of mice groups treated with chicken cathelicidin displayed high area of necrosis compared to untreated EAC-bearing mice. Based on histological analysis and immunohistochemical staining revealed that the tumor section in Ehrlich solid tumor exhibited a strong Bcl2 expression in untreated control compared to mice treated with 10 & 20 µg/ml of cathelicidin. Interestingly, low expression of Bcl2 were observed in mice taken 40 µg/ml of CATH-1. This study drive intention in treatment of cancer through the efficacy of anticancer efficacy of chicken cathelicidin peptides.
