Abstract
Background: Global Positioning System (GPS) devices are widely used in soccer for monitoring external load indicators (ELi) with the aim of maximizing sports performance, while potentially reducing the risk of injury. The aim of this study was to investigate the ELi differences in players of different playing positions (i.e., central backs, external strikers, fullbacks, midfielders, strikers, wide midfielder) and among different sport-specific tasks.Methods: 1932 observations from 28 semi-professional soccer players (FC Palermo, Italy, age: 25±6 years, height: 183±6 cm, weight: 75.2±7 kg) were collected through GPS devices (Qstarz BT-Q1000EX, 10 Hz) during the season 2019-2020. Participants were monitored during Official Match (OM), Friendly Matches (FM), Small Sided Games (SSG), and Match-Based Exercises (MBE). Metabolic (i.e., metabolic power, percentage of metabolic power > 35w, number of intense actions per minute, distance per minute, passive recovery time per minute) and neuromuscular indicators (i.e., percentage of intense accelerations, percentage of intense decelerations, change of direction per min > 30°) were recorded during each task.Results: ANOVA showed significant differences in ELi between player positions within each task and between tasks (p <0.05). Conclusion: In semi-professional soccer players, different ELis were detected for players’ positions showing the highest values during OM. Coaches should consider the different physical responses to different physical tasks and player position to design the most appropriate training program.

Abstract
Background: This study aimed to assess the current awareness and practices of resin composite light curing of general dental practitioners (GDP) in Saudi Arabia. Methods: A population of 250 general dentists appointed in non-university governmental hospitals in five main cities in Saudi Arabia was targeted with a sample size of 152 at 95% power. 250 email invitations were sent individually to join the survey voluntarily and anonymously. Descriptive statistics and Chi-square test were used to analyze the obtained responses. Results: 156 responses were received. Chi-square test showed no statistical significance in participants satisfaction of their employed light curing technique regardless of the curing unit they use. Participants vary regarding their awareness of the significance and criteria of proper light curing and resin composite material related factors. Conclusion: There is no uniform light curing technique followed by dentists. Dentists need to improve their knowledge and clinical skills of light curing resin composite.
Larval digestive system ontogeny and early weaning in neon tetra Paracheirodon innesi

Published: June 2022

Abstract
The intensive culture of characid teleosts for ornamental trade is highly dependent on live feed organisms, particularly Artemia nauplii, to provide nutrition through the larval stage. Live feeds have inherent disadvantages relative to prepared microparticulate diets (MDs), specifically availability, labor and cost. In this research, the dependence of larval Paracheirodon innesi on live Artemia was confirmed via a dietetics trial. Next, digestive system ontogeny was characterized from the onset of exogenous feeding through metamorphosis. P. innesi exhibited an agastric larval stage, as well as low digestive enzyme activity at the onset of exogenous feeding followed by abrupt increases in trypsin, lipase and pepsin activity. Differentiation of the stomach, including gastric gland formation and production of neutral mucopolysaccharides, as well as the onset of pepsin activity, did not occur until 20 days post hatch (dph). This shift from agastric to gastric digestive modes is indicative of a proliferation of digestive capacity and subsequent prey diversity in other fish species exhibiting similar altricial larval stages. Based on this information, different schedules for weaning from Artemia to a MD were evaluated. For P. innesi fed until 32 dph, weaning beginning at 12 dph and 17 dph resulted in similar survival to live Artemia (mean: 22.0 ± 1.7%), and the MD resulted in the lowest survival (0.8 ± 0.3%). These results indicate that weaning is possible prior to gastric differentiation, potentially resulting in the reduction of Artemia use in the larval culture P. innesi.

Published: June 2022

Abstract
The stunning success of deep image classification approaches relies heavily on huge, labeled datasets based on real-world images. Nonetheless, the latest generation of neural network architectures provides pre-trained models that allow the training and classification of new classes with only minor example data. In most application use cases, the prediction performance is still too low to meet the high standards of manufacturing systems, e.g., for visual part classification. Furthermore, it is often difficult to acquire sufficient image data of objects in manufacturing systems due to customized and small batch production. While data augmentation techniques like viewport transformations or artificial noise barely increase the data set's overall entropy, we aim to generate highly realistic synthetic images only based on photorealistic rendered CAD. Additionally, this approach can reduce manual effort in data generation and preparation.First, we demonstrate the creation of a parametric rendering pipeline. Then the models are trained for a 30-class classification problem with typical engineering parts from an industrial use case. Finally, we show how the entropy gain, using our proposed method, improves the classification performance in any of the investigated deep image classification models.

Abstract
Background: Pancreatic adenocarcinoma (PAAD) is the most common histological subtype of pancreatic cancer. Although dramatic progress has been made in multimodal therapies, PAAD still has a poor diagnosis and prognosis. The integrin α (ITGA) family genes play a fundamental role in different cancers. However, the potential values of ITGA family members in PAAD remain elusive. This study aimed to analyze the relationship between and ITGA family genes and PAAD.Methods: A variety of bioinformatic approaches, including UALCAN, GEPIA, Human Protein Atlas (HPA) database, Kaplan-Meier Plotter, cBioPortal, and STRING, which were used to analyze the potential roles of ITGA family members in human PAAD. The results were further verified in PAAD cell lines.Results: The transcriptional levels of ITGA 1/2/3/5/6/9/11 were up-regulated, whereas the expression of ITGA 4/8/10 were not obvious in patients with PAAD compared with that in normal pancreas. And a noticeable correlation was also discovered between the over-expressions of ITGA 2/3/5/6/11 and the clinical cancer stages of PAAD patients. Survival analysis revealed that the high mRNA expression of ITGA 2/3/5/6 and 11 were associated with overall survival (OS) in PAAD patients.Conclusion: Detection of ITGA genes has values in the diagnosis and prognosis of PAAD. ITGA 2/3/5/6/11 might serve as indicators of tumor stages of PAAD, while ITGA 2/5 may be new biomarkers for evaluating the prognosis of PAAD.

Abstract
Viruses play a central role in all ecological niches; the origin of viruses, however, remains an open question. While phylogenetic analysis of distantly related viruses is hampered by a lack of detectable sequence similarity, structural biology can reveal conserved capsid protein structures that facilitate the study of distant evolutionary relationships. Here, we characterize the lipid-containing ssDNA temperate bacteriophage ΦCjT23, which is infecting Flavobacterium sp. (Bacteroidetes). We further detected ΦCjT23-like sequences in the genome of strains belonging to several Flavobacterium species. The virion structure determined by cryogenic electron microscopy revealed similarities to members of the viral kingdom Bamfordvirae that currently consists solely of dsDNA viruses. Common to these viruses, infecting hosts from all domains of life, is a major capsid protein composed of two upright β-sandwiches. The minimalistic structure of ΦCjT23 suggests that this phage serves as a model for the last common ancestor between ssDNA and dsDNA viruses in the Bamfordvirae. Both ΦCjT23 and the related phage FLiP infect Flavobacterium species found in several environments, suggesting that these types of viruses have a global distribution and shared evolutionary origin. Detailed comparisons to related, more complex viruses not only expand our knowledge about this group of viruses but also provide a rare glimpse into early virus evolution.

Published: June 2022

Abstract
Contamination of water resources with nitrate is an increasing worldwide phenomenon that requires attention, particularly in areas with high vulnerability such as Gaza, Palestine.
The study presented the areas where nitrate concentrations are expected to impose health risks using Geographic Information System (GIS) application to present the most at risk areas.
The highest risk areas, located in the North and Khan Younis governorates of Gaza Strip, were shown on maps based on a proposed vulnerability criteria that consider the potential health risk (hazard quotient for nitrate >1), the level of poverty (>50%), and the level of water salinity (TDS<1000 mg/l). Residents of those areas, particularly infants, are more prone to health risks due to their higher vulnerabilities, and therefore, special advisory need to address them by the designated municipality. In addition, more strategic interventions to ensure the provision of alternative safe water supply need to be undertaken.

Published: June 2022

Abstract
Background Clinically useful and adequately validated predictive models of bronchopulmonary dysplasia (BPD) available at or soon after birth, especially for the Chinese population are few. This study aims to develop and validate a predictive model for the identification of BPD at early stage and the generation of a nomogram for clinical use.Methods This retrospective study developed a well-validated predictive model of BPD among preterm infants with gestational age (GA) of less than 32 weeks by logistic regression and generated a nomogram.Results This model comprised six variables, i.e., GA, birthweight, neonatal asphyxia, invasive ventilation, neonatal respiratory distress syndrome (NRDS), and patent ductus arteriosus (PDA). The regression equation was Logit P = (15.209 – 0.076 × GA – 1.001 × birthweight + 0.557 × neonatal asphyxia + 1.083 × invasive ventilation + 0.622 × NRDS + 0.656 × PDA). The area under the receiver operating characteristic (ROC) curve of this model was 0.856 (95% CI: 0.812–0.901), with sensitivity of 81.6% and specificity of 76.8%. The verification of this predictive model showed a sensitivity of 93.5% and specificity of 76.5%, demonstrating that the effects of this model were satisfactory.Conclusions This risk prediction model had a good predictive effect for the risk of BPD in premature infants with GA less than 32 weeks and could furnish evidence for preventive treatment and intervention.

Abstract
Background: Breast cancer prevalence is observed to be higher in developed economies, but the mortality rates due to the said disease tend to be similar or even higher among lower-income countries. Afghanistan is among these countries where breast cancer mortality has been predominant among the female population. This may be related late diagnosis and the presentation of the cancer at much later stages.Methods: This is a cross-sectional study using a survey questionnaire administered from June 2021 to July 2021 among women living in Herat province of Afghanistan. It evaluated their knowledge and practice towards breast cancer. 534 women answered the survey. Data was analyzed using IBM SPSS software.Results: Lower level of knowledge about breast cancer and the limitations to the practice of breast self-examination (BSE) were found to be associated with such late detection and treatment. Using data collected in Herat Province of Afghanistan, this study examined the individual level sociodemographic factors related with the level of knowledge about breast cancer and also with the practice of BSE. It was found that 44% of the study sample of 534 women had high knowledge level. There were fewer still who performed BSE at about 12% of the respondents. Further examination showed that lower education attainment, albeit illiteracy, and the employment status were correlated with knowledge and practice surrounding breast cancer.Conclusion: This entails the need to formulate programs targeting the specific needs of women with lower socioeconomic status to build capacity toward their health and wellbeing.

Abstract
IntroductionThe aim of this study was to evaluate if an automated measurement of lung lesions, epicardial fat and pericardial volume during the days surrounding hospital admission for COVID-19 pneumonia may predict intubation or mortality. The second purpose of this study was to assess whether the association of these Computed Tomography (CT) measures with the SOFA (Sequential Organ Failure Assessment) score, could predict intubation and mortality better than the SOFA score alone.MethodsThis observational retrospective study was conducted in Timone university hospital in Marseille in France, between March 10th and May 10th 2020. All adult patients with COVID-19, admitted with respiratory symptoms and having performed a chest CT three days before to two days after admission were eligible for inclusion. All chest CTs were analyzed using a local automated CT measurement software. The primary outcome was invasive mechanical ventilation (IMV) or death during the 60-day follow-up. Wilcoxon-Mann-Whitney test was used for univariate analysis and logistic regression were calculated for multivariate analysis. Results176 patients were included in the study. 57 (32.4%) received IMV or died during the 60-day follow-up. After univariate analysis, all lung automated volumetric measures of ground-glass (p=0.015), consolidation (p<0.001) and all lesions to parenchymal volume ratio (p<0.001) were significantly higher for the patients who required IMV or who died. All pulmonary-lesion rate was tested in multivariate analysis and remained significantly higher in the IMV or death group (p=0.003), with an Odd Ratio of 3.52 (1.55-8.01, 95% CI) for patients who had more than 19.5% of pulmonary lesion. Pericardial volume and epicardial fat were not significantly associated with IMV or mortality. In this study, the association of the criterion “pulmonary lesion >20%” to the SOFA score improves its predictive value on IMV or mortality with a AUC of 0.82.ConclusionAutomated chest CT measures of COVID-19 patients with respiratory symptoms admitted to hospital showed a significantly higher rate of lung lesions (ground glass, consolidation, or both) for those who later died or required IMV. Furthermore, the association of these automated CT measures to the SOFA score could help select patients requiring ICU upon entering hospital.

Abstract
Purpose
Although the use of microbial fertilizers is still far lower than that of chemical fertilizers in the planting industry, it has still received much attention for its non-toxic and pollution-free characteristics. Here a promising bacterial strain was successfully isolated from the tomato rhizosphere and identified as Bacillus Safensis YY-01 with 16S rDNA sequence, which was found to significantly enhance both the growth of tomato and the relative abundance of beneficial microorganisms such as Bacillus, Chaetomium, Proteobacteria, Actinobacteria, and Chloroflexi. B. Safensis YY-01 may be a strong candidate as one bacterial strain of microbial fertilizers.
Methods
B. Safensis YY-01 was isolated and cultured, which was used as leaf fertilizer to spray on the phylloplane of tomato every week. The effect of B. Safensis YY-01on the height, chlorophyll, and peroxidase (POD) activity of tomato was investigated, moreover, the microbial community structure of tomato rhizosphere soil was analyzed through high-throughput sequencing technology.
Results
Compared with the control, the height, chlorophyll A, chlorophyll B, total chlorophyll, and POD activity of tomato Haoliang No.998 were increased by 12.8%, 17.1%, 11.8%, 14.8%, and 37.5%, respectively, and yingfen No.8 were increased by 14.1%, 7.8%, 10.2%, 10.7%, and 7.3%, respectively. Further, the microbial community structure in rhizosphere soil of tomato Haoliang No.998 was analyzed and showed that the relative abundance of beneficial microorganisms such as Proteobacteria, Actinobacteria, Chloroflexi, Bacillus, and Gemmatimonadota increased significantly, and the relative abundance of tomato yingfen No.8’s Acidobacteriota, Actinobacteria, and Bacillus were also increased significantly.
Conclusion
A promising bacterial strain of B. Safensis YY-01 was successfully isolated, which was beneficial to both the growth of tomatoes and the relative abundance of helpful microorganisms in the rhizosphere soil of tomatoes.

Published: June 2022

Abstract
Heterogenous scene matching is one of the key technologies in the field of computer vision. The image rotation problem has been a hot and difficult problem in the field of heterogenous scene matching. In this paper, a heterogenous scene matching method based on the gradient direction distribution field is proposed. The Distributed field theory is introduced into the heterogenous scene matching for the first time. First, the gradient direction distribution field is constructed and fuzzified, and then the effective regions are selected. Then, the concept of main direction distribution field is defined to solve the matching errors due to the existence of rotational transformations between heterogeneous source images. Third, the Chi-square distance is introduced as a similarity measure. At last, the hill-climbing method search strategy is adopted, which greatly improves the efficiency of the algorithm. Experimental results on 8 pairs of infrared and visible heterogenous images demonstrate that the proposed method outperforms the other state-of-the-art region-based matching methods in terms of robustness, accuracy and real-time performance.

Abstract
Here we present the results of the first measurement of the 2S1/2, F=0 -> 2P1/2, F=1 transition in Muonium, the hydrogen-like bound state of a positive muon and an electron. The measured value of 580.6+-6.8 MHz is in agreement with the theoretical calculations. From this measurement a value of the Lamb shift of 1045.5+-6.8 MHz is extracted, compatible with previous experiments. We also determine for the first time the 2S hyperfine splitting in Muonium to be 559.6+-7.2 MHz.
The measured transition being isolated from the other hyperfine levels holds the promise to provide an improved determination of the Muonium Lamb shift at a level where bound state QED recoil corrections not accessible in hydrogen could be tested. Such a measurement will also be sensitive to new physics in the muonic sector, e.g. to new bosons which might provide an explanation of the g-2 muon anomaly or Lorentz and CPT violation. We also present the first observation of Muonium in the n = 3 excited state opening up the possibility of new precise microwave measurements as realized in hydrogen.
