Implementing Path of Zhengzhou University\u27s Establishment of Football Academy

Under the new policy background of the 2020 Opinions on Deepening the Integration of Sports and Education and Promoting the Healthy Development of Adolescents , as the highest educational institution in China, higher education institutions should shoulder the responsibility of cultivating high-quality talents to meet social needs. As the highest-quality higher education institution in Henan Province, Zhengzhou University\u27s innovation and exploration of teaching methods and talent training models under the background of the integration of sports and education will play a leading role in the development of higher education in Henan Province. Through combing and analyzing the existing policy documents, firstly, explore the reasons, significance, and social background of the construction of the football academy; secondly, analyze the theoretical basis for the construction of the football academy in the context of relevant policies, and analyze the demand for talent training required by the policy. It was combining with the construction situation of my country’s football academy at this stage, implementing the specific requirements of the integration strategy of sports and education, establishing the guiding ideology of “diversified integration” after establishing the academy from the three levels of discipline establishment, talent training, and talent transfer. Investigate the needs of the talent market at the stage, determine the direction of talent training, and discuss how to set up specific majors for domestic enrollment after the establishment of the college. Based on this, it proposes the professional setting direction and specific curriculum arrangement and assessment methods for talent training from five aspects: education and teaching, sports competitions, sports medicine, sports media, economics, and management. Finally, it discusses the difficulties faced by students, teachers, and employment development after graduation in the process of football academy construction and how to use existing resources and related policy support to solve the difficulties. As an innovative way of running a school, the Football Academy provides new opportunities for the reform and innovation of sports talent cultivation. In the torrent of sports and education integration reform, make full use of existing resources, integrate and mobilize various high-quality resources in the region, and finally transform them into the winning resources for the new development of our school\u27s sports discipline in this innovative school-running method. After the football academy is established, it will become a link between campus football and professional football in the province, and a breeding base for national high-quality football industry talents. It will also provide a strong impetus for the development of football in my country

An Analysis of the Construction and Development of ‘Starry Star’ Training Camp in Zhengzhou City

Since 2017, the Ministry of Education has taken the lead in establishing the \u27Starry Star\u27 pilot training camp. As a leading city of school football campaign/activity, Zhengzhou City takes up heavy responsibility of continuously promoting the rapid development of school football in Henan Province. This paper adopts such methodologies such as literature, fieldwork, mathematical statistics and logical analysis to identify the weaknesses in the current phase of construction and to make reasonable recommendations according to policies and the actual situation for pointing out the direction for the future development. In terms of organizational leadership, all relevant policies and documents are well-developed reflecting the high degree of importance attached to each training camp, but very few of them have omissions in the development of the system of admissions and training management regulations. In terms of condition guarantee, three aspects are prominent, including the treatment of coaches (calculation of hours), the size of the training grounds at each training site not meeting the requirements of the camps\u27 participation groups (due to limited size of the campus), and the lack of implementation of supporting funds (in the surrounding counties). In terms of competition and training, all schools lost points to varying degrees in the various detailed assessment indicators of the survey and assessment such as inappropriate teaching attitude of the teaching staff, unsystematic training syllabus, unfinished work arrangements for two tournaments and one practice and insufficient attention to the campers\u27 performance in cultural subjects. In terms of reserve training and training participation rate, nearly 30% of the camps failed to send outstanding athletes to higher level schools; half of the camps failed to ensure over 90% attendance of campers. It is suggested that relevant authorities should in future give standardized and clear policies regarding admissions and other related systems. Further, the authorities should clarify the way of coaches\u27 salary and title appraisal, focus on the implementation of matching funds for training camps, and gradually adjust the correspondence between matching camper groups and camp site conditions. As the main task of the Starry Star training camps, more attention should be placed in future work, improving policies, seriously correcting and dealing with various situations that affect the quality of race training in each camp. The authorities should optimize the way of supplying outstanding athletes, and at the same time strengthen regular inspections and random checks for the attendance, putting equal emphasis on training quality and participation

Evaluation of Neck Lymph Node Metastasis on Contrast-Enhanced Ultrasound: An Animal Study

Objectives To assess the performance of contrast-enhanced ultrasound (CEUS) intended to differentiate hyperplastic from malignant neck lymph nodes in an animal model. Methods Twenty-four New Zealand rabbits were randomly divided into two groups: neck lymph node metastasis group (12 rabbits) and reactive hyperplastic lymph node group (12 rabbits). Tongue VX2 carcinoma with cervical lymph node metastasis was induced in 12 rabbits by injecting VX2 carcinoma suspension into the left tongue submucosa. Hyperplastic neck lymph nodes were induced by injecting egg yolk in the submandibular region of the rabbits in hyperplastic group. CEUS were performed in both groups before and after intravenous administration of SonoVue. The site, number, echogenicity, longitudinal and transverse nodal dimensions, patterns of enhancement of the neck lymph nodes were observed and recorded. Results In both groups only one lymph node was found in the left (tumor) side of the neck. CEUS found 12 of 12 metastatic lymph nodes in metastasis group, and diagnosed 11 of 12 lymph nodes as metastatic. Histopathologic analysis revealed metastatic lesions in all 12 rabbits, each with one lymph node, and all 12 lymph nodes in hyperplastic group is inflammation lymph nodes. All 12 cases in the hyperplastic group showed centripetal homogeneous enhancement while in the metastasis group one case showed centripetal homogeneous enhancement, three cases showed centrifugal heterogeneous enhancement, and eight cases showed diffused heterogeneous enhancement. Only one lymph node was dissected on the left side of the neck in each rabbit in both groups. Conclusion CEUS can play a role in discriminating metastatic from hyperplastic lymph nodes in head and neck carcinoma

Local nearly non-strained perovskite lattice approaching a broad environmental stability window of efficient solar cells

Twist and fracture of surface lattice tend to occur under harsh condition due to the soft lattice natures of hybrid perovskite materials. Accordingly, surface defects and lattice distortion are produced, which allow the performance loss and notorious degradation in perovskite solar cells (PSCs). In our work, judiciously selected conjugated ligand was employed as the film intermediary, from which rigid and delocalization 4-phenylpyridine (4-pPy) exhibited the most significant improvement on both optoelectrical performance and stability of PSCs. By regulating the film crystallization kinetics, high-quality perovskite films can be obtained with preferable crystal orientation. Moreover, benefiting from the defects passivation and unidirectional bonding effect, coordinated 4-pPy “scaffold” on the lattice surface could mitigate vacancy formation and lattice twist/fracture under severe conditions. The resulted p-i-n planar device shows a considerable PCE of 21.12% (certified 20.2%) with negligible hysteresis, as well as an excellent storage (90% of original PCE after 1000 h at 60% RH), operating (90% of original PCE after 600 h at maximum power point) and thermal stress (89% of original PCE after 500 h at 85 °C) stability. It is hoped that our findings could open a new way to accelerate continued progress on PSCs regimes for efficieny maximization and stability prolongation

Composition and Functions of Highland Barley Bran with Different Milling Rates

For a better understanding of the difference in functional components and functions among different parts of highland barley bran, the contents of protein, β-glucan and polyphenol, antioxidant activity, and alkyl radical intensity in highland barley bran with various milling rates were compared. The results showed that the contents of total protein, albumin, globulin, glutenin, free polyphenol, bound polyphenol, free flavone, bound flavone and condensed tannin first increased and then decreased with increasing milling rate. Protein mainly existed in bran flour with a milling rate of 17.74% and 19.22%. Bran flour with 9.7% milling rate had the highest phenol content, and the trend in antioxidant activity was consistent with that in the content of phenols. The contents of β-glucan and gliadin increased from outside to inside, and reached the highest value at a milling rate of 25.99%. Alkyl radical intensity was significantly higher at 1.54%–5.84% milling rates than at 7.67%–25.99% milling rates, indicating a higher susceptibility to oxidation. The findings of this study provide a theoretical basis for the deep processing of different layers of highland barley bran

Effects of Hunger on Visual Perception in Binocular Rivalry

The effect of hunger on visual perception is largely absent from contemporary vision science. Using a well-established visual phenomenon termed binocular rivalry, this study was carried out to investigate the effects of hunger on visual perception. A within-subject design was applied in which participants attended two sessions before and after their lunch or dinner, i.e., a hunger state and a satiated state. In Experiment 1, we found that the mean dominance times to food-related pictures were larger in the hungry condition than that in the satiated condition, while the mean dominance time to the non-food stimuli were unaffected. In Experiment 2, we found the times to break through continuous flash suppression (b-CFS) for both food-related and non-food-related pictures were not affected by hunger. In Experiment 3, a probe-detection task was conducted to address possible response-biases. Our findings provide evidence that hunger biases the dynamic process of binocular rivalry to unsuppressed and visible food stimuli, while processing suppressed and invisible food-related was unaffected. Our results support the notion that the top-down modulation by hunger on food-related visual perception is limited to visible stimuli

Investigation of the Impact of Land-Use Distribution on PM2.5 in Weifang: Seasonal Variations

As air pollution becomes highly focused in China, the accurate identification of its influencing factors is critical for achieving effective control and targeted environmental governance. Land-use distribution is one of the key factors affecting air quality, and research on the impact of land-use distribution on air pollution has drawn wide attention. However, considerable studies have mostly used linear regression models, which fail to capture the nonlinear effects of land-use distribution on PM2.5 (fine particulate matter with a diameter less than or equal to 2.5 microns) and to show how impacts on PM2.5 vary with land-use magnitudes. In addition, related studies have generally focused on annual analyses, ignoring the seasonal variability of the impact of land-use distribution on PM2.5, thus leading to possible estimation biases for PM2.5. This study was designed to address these issues and assess the impacts of land-use distribution on PM2.5 in Weifang, China. A machine learning statistical model, the boosted regression tree (BRT), was applied to measure nonlinear effects of land-use distribution on PM2.5, capture how land-use magnitude impacts PM2.5 across different seasons, and explore the policy implications for urban planning. The main conclusions are that the air quality will significantly improve with an increase in grassland and forest area, especially below 8% and 20%, respectively. When the distribution of construction land is greater than around 10%, the PM2.5 pollution can be seriously substantially increased with the increment of their areas. The impact of gardens and farmland presents seasonal characteristics. It is noted that as the weather becomes colder, the inhibitory effect of vegetation distribution on the PM2.5 concentration gradually decreases, while the positive impacts of artificial surface distributions, such as construction land and roads, are aggravated because leaves drop off in autumn (September–November) and winter (December–February). According to the findings of this study, it is recommended that Weifang should strengthen pollution control in winter, for instance, expand the coverage areas of evergreen vegetation like Pinus bungeana Zucc. and Euonymus japonicus Thunb, and increase the width and numbers of branches connecting different main roads. The findings also provide quantitative and optimal land-use planning and strategies to minimize PM2.5 pollution, referring to the status of regional urbanization and greening construction
