Authors: Zhou Yongqin , Huang Jianxin , Zhou Lei , Tian Hongbo
Published: August 2022

To solve the complex calculation in the reliability evaluation of the motor system with the Markov model, this study developed a reliability evaluation method based on the hidden Markov model (HMM). Next, the developed method was employed in a type of permanent magnet hybrid segmented flux-switching machine (PMFSM). By analyzing and simplifying the components of the PMFSM system, the reliability measurement standard and the failure modes of the respective component were examined, and the relationships between the failure modes of each component and the system parameters were built. The optimal parameter observation sequence was determined by calculating the Minkowski distance, and the HMM was iteratively calculated by using the Baum–Welch algorithm. Moreover, the state transition probability matrix of the system was built, and the system reliability was evaluated. As revealed from the calculation results, the reliability of the PMFSM system is significantly higher than that of the conventional structure at the same time, and the mean time to failure (MTTF) of the PMFSM system is 14.8% higher than that of the conventional structure. Compared with the conventional evaluation method based on the Markov model, the two methods have similar reliability results for conventional and novel PMFSM systems, and the variation trend is the same. It shows that the proposed reliability evaluation method is feasible and effective, and the calculation is simple. The work in this study provides a basis for the design of the novel PMFSM system, and a practical engineering method to efficiently evaluate the reliability of other motor systems.
Emission of Methane From Wetland Paddy Fields: A Review
Authors: Twinkle Devi Naorem , Sarjubala Devi Angom , Singh Khoiyangbam Raju
Published: August 2022

Cultivation of rice is widely practiced throughout the world as rice is a staple food for half of the world’s population. However, the emission of methane (CH4) is an issue associated with the cultivation of rice. Many reports on the level of CH4 emission after treatment of different kinds of organic materials in paddy fields were reported. It was observed that the application of a combination of tested locally available compost along with inorganic NPK fertilisers effectively reduced the rate of emission of CH4. Intermittent wetting and drying in addition to the combined application of compost and NPK fertilisers will help in reducing the emission of CH4 up to 40 to 45%. To undertake an intermittent drainage system is a difficult step for the farmers to implement as it has extra cost and labour. Therefore, lawmakers should initiate steps to help farmers in order to reduce the emission of CH4 from paddy fields.

Authors: Lalthanpuia  , Laldinpuii H. , Lalmalsawma Samuel , Hrahsel James Lalnunzira
Published: August 2022

Mizoram, one of the north-eastern states in India, predominantly consists of hilly terrain with tribal populations living in villages scattered along the upper reaches. The high dependency of people on natural resources and rainfed agricultural practices relying wholly on the southwest monsoon make the region highly vulnerable to climate change exacerbated by poor development infrastructure, land use and land cover change, forest loss and degradation. The vulnerability of the state needs to be addressed to assist in developing practical and reliable plans to increase resilience against long term climate change. The intrinsic properties corresponding to sensitivity and adaptive capacity of the state in terms of domestic water resources availability are focused here to assess inherent vulnerability to unprecedented changes than can be caused by climate stress. The assessment follows an analytical framework by selecting indicators that define vulnerability criteria across all the districts in the state. Indicators were given weights per the best reflection to ground reality by means of stakeholder consultations. Composite Vulnerability Index (CVI) was calculated for each district across all indicators. Districts were ranked and categorised into high, medium, and low vulnerability based on their CVI values. Drivers of vulnerability were determined by calculating the contributions of each individual indicator to overall vulnerability. The calculated CVI was highest for Champhai making it the most vulnerable district. CVI was lowest for Mamit making it the least vulnerable district. Across all districts, limited availability of perennial springs per household, less forest cover and limited availability of ground water resources were the top drivers of overall vulnerability.

Authors: Meena Mamta
Published: August 2022

Since historical times, the climate of the earth has been changing. In terms of diversity and population, India is a vast country. Any significant change in its climatic conditions can have an impact on the country’s entire economic and cultural structure. Temperature is the most important variable when focussing on climate change study. This study aims to recognise the changing trend of temperature in India. For this purpose, temperature data from 1901 to 2020 has been analysed. To find out the variability in temperature, various statistical tools were applied. The Mann-Kendall method has been used along with Sen’s slope estimator for determining the trend and slope magnitude. ARIMA modelling is applied to the data series to forecast the temperature trend. The study has shown that variability in temperature is increasing in recent years and the temperature trend is increasing in all the months, especially in the cold months of November, December and January. The average annual temperature of India in the year has increased significantly in the past 120 years. The trend analysis of temperature is tested significantly statistically at a 95% confidence level.
Environmental Education of Students Pursuing Higher Education: Probing on Climate Change Awareness
Authors: Castillo Jane Salvador , Nozaleda Bryan M.
Published: August 2022

Several studies argued that the inclination of individuals to participate in activities aiming at environmental conservation emanates from their degree of awareness of the existing problem. Hence, this study examined the level of awareness of students of Batanes State College, Philippines, towards climate change and compare their knowledge to the individual backgrounds. The researchers used a survey questionnaire as the primary tool for gathering data. Mean and percentage were used to describe the profile of the respondents and their awareness of climate change while Chi-Square Test was used to determine the significant difference in the awareness of the respondents in terms of their profile. The results showed that the students demonstrated a moderate level of awareness of the occurrences, causes and consequences of climate change. When compared against their personal backgrounds, the result revealed that there is no significant difference in their level of climate change awareness. This moderate level of awareness towards climate change, despite the harsh weather conditions frequently experienced in Batanes, calls for intensifying the school’s efforts in raising awareness of the occurrence, consequences, and causes of climate change. Consequently, these actions will eventually improve the attitude and behaviour of the students to take active participation in the protection of the environment.

Authors: Ambildhuke Geeta Mahadeo , Gupta Banik Barnali
Published: August 2022

Rainfall prediction is the most significant requirement nowadays due to the chaotic nature of climate. Climate has changed drastically over the last few years due to global warming and has become very unpredictable. Rainfall prediction is essential for decision-making in various sectors like agriculture, transportation, tours and travels, outdoor events, etc. In this study, machine learning algorithms are analysed and experimented on the dataset comprising various atmospheric parameters of Hyderabad city in Telangana. The work is carried out on individual popular classifiers, namely Naïve Byes, Decision Tree, Random Forest, K nearest neighbour, and Support Vector Machine. The performance is compared with techniques like voting classifiers and stacking ensemble. The experiment gives predictions on the rainfall intensity as No Rain, Low to Medium rain, or Heavy rain. The k-cross-fold validation technique is used as the evaluation metric, which is very effective and results in less biased estimations. The aim is to provide the decision-making capabilities based on the mentioned intensity of rainfall that can be very useful in managing the irrigation cycle in the agriculture field, deciding on an outdoor event, or any travelling plan based on the current atmospheric parameters. The platform used is python, which is portable, open to access, and available easily.

Reliability and discriminant validity of the quantitative timed up and go in typically developing children and children with cerebral palsy GMFCS levels I-II
Authors: Smith Julianna , DiVito Michelle , Fergus Andrea
Published: August 2022

PURPOSE: The purpose of this study was to examine the reliability and discriminant validity of the Quantitative Timed up and Go (QTUG) in typically developing (TD) children and children with cerebral palsy (CP). METHODS: Twenty-eight TD children and 8 with CP (GMFCS I-II) completed 3 TUG trials while wearing QTUG sensors. Test-retest reliability and discriminative ability were examined for the 57 constituent parameters of the TUG. Relationships between age and these parameters were also examined. RESULTS: Forty-four of the parameters demonstrated moderate to excellent test-retest reliability, with measures of angular velocity being the most reliable. Twenty-six parameters were different between TD children and those with CP, and twenty-eight gait parameters demonstrated correlations with age, further supporting its discriminative ability. CONCLUSION: The QTUG is a clinically feasible tool that is capable of both reliably measuring and discriminating many of the movement parameters with the TUG mobility task in TD children and those with CP GMFCS I-II. The results of the present study provide preliminary evidence that the QTUG can discriminate between children on several of the gait parameters within the TUG.

Authors: Kim Jeonghui , An Mihee , Kim Janggon
Published: August 2022

PURPOSE: The Measure of Processes of Care for Service Providers (MPOC-SP) is a valid and reliable instrument to measure the professionals’ perception of the extent to which they apply the principles of family-centered services in care for children with disabilities. This study aimed to evaluate the validity and reliability of the Korean translation of the MPOC-SP (Korean MPOC-SP). METHODS: The Korean MPOC-SP was completed by 132 rehabilitation service providers in 5 provinces in South Korea. Analyses for internal consistency, construct validity, and test-retest reliability were performed. RESULTS: The estimates of internal consistency (Cronbach’s alpha) of the four scales of the Korean MPOC-SP ranged from 0.67 to 0.92. All the scales correlated highly with the other scales (r ranging from 0.61 to 0.77). In addition, all the items exhibited high item-total correlations (rs ranging from 0.40 to 0.83). Three scales had moderate to good reliability with ICCs ranging from 0.57 to 0.78; the ‘providing general information (PGI)’ scale showed low reliability (ICC 0.22). CONCLUSION: The Korean MPOC-SP can be considered a valid instrument for group-level research purposes with acceptable internal consistency, but caution is warranted regarding the low test-retest reliability of the PGI scale.
Environmental, Social, Governance Financing Goals in Post-COVID-19 World
Authors: Sinha Ria , Juneja Mani
Published: August 2022

The paper is based on the increased importance of environmental, social, and governance factors in the present-day investing, especially in the COVID-19 pandemic period. The increased trends are not only witnessed in developed economies but also evident in developing economics like India. The possible reasons are attributable to enhanced risk awareness and sensitivity of institutional investors towards ESG issues, thereby, leading to price discovery of ESG factors through increased integration in investment portfolios. The need for prioritizing social investments is clear, especially after the onset of the pandemic. However, the major barriers appear to be lack of relevant knowledge on ESG issues and apathy of investors in formulating an ESG investing framework. The paper provides certain insights on the present-day ESG frameworks and principles that can be adopted by financial managers and asset management companies to generate better risk adjusted returns.
Morph-KGC: Scalable knowledge graph materialization with mapping partitions
Authors: Arenas-Guerrero Julián , Chaves-Fraga David , Toledo Jhon , Pérez María S. , Corcho Oscar
Published: August 2022

Knowledge graphs are often constructed from heterogeneous data sources, using declarative rules that map them to a target ontology and materializing them into RDF. When these data sources are large, the materialization of the entire knowledge graph may be computationally expensive and not suitable for those cases where a rapid materialization is required. In this work, we propose an approach to overcome this limitation, based on the novel concept of mapping partitions. Mapping partitions are defined as groups of mapping rules that generate disjoint subsets of the knowledge graph. Each of these groups can be processed separately, reducing the total amount of memory and execution time required by the materialization process. We have included this optimization in our materialization engine Morph-KGC, and we have evaluated it over three different benchmarks. Our experimental results show that, compared with state-of-the-art techniques, the use of mapping partitions in Morph-KGC presents the following advantages: (i) it decreases significantly the time required for materialization, (ii) it reduces the maximum peak of memory used, and (iii) it scales to data sizes that other engines are not capable of processing currently.

Published: August 2022

O consumo médio de pescado no Brasil é abaixo do mínimo recomendado pela OMS. Entre os vários fatores para o baixo consumo desse alimento estão a falta de preferência em relação a outros tipos de carnes, a falta de conhecimento no preparo do pescado e a pouca variabilidade de produtos de pescado destinados à comercialização. Portanto, o objetivo do estudo foi avaliar aspectos físico-químicos e nutricionais de marinados de filés de tilápia-do nilo (Oreochromis niloticus) submetidos à tecnologia do ultrassom. Os filés de tilápia marinados submetidos ao ultrassom (US) foram mais escuros, menos vermelhos e menos amarelos que os filés de grupo controle (CON). A aplicação do ultrassom (US) não causou modificações nos parâmetros de textura e pH com o tratamento CON. Os filés de tilápia marinados com a presença de US apresentaram menor atividade de água (Aw). As bases nitrogenadas voláteis não apresentaram variações entre os tratamentos. Os marinados submetidos a US apresentaram maior umidade. Os demais componentes nutricionais (lipídeos, proteínas e cinzas) não apresentaram diferença entre tratamentos. Observa-se, portanto, um grande potencial de utilização do ultrassom em filés marinados de tilápia, principalmente pela influência positiva na segurança alimentar (menor Aw) sem interferir na proteína, na gordura e nas cinzas.

Determination of yield of fractional material bydestruction of martiteore by water jets depending on the direction of their cutting
Authors: Kovbyk K
Published: August 2022

Purpose. Highlight the main results of the experiments performed on the destruction of martite ores by the method of borehole hydraulic destruction by their layering. Since, as a result of the analysis of literary sources, it was established that some of the deposits of the Kryvyi Rihiron ore basin are suitable for hydro monitor excavation.Consideration of the method of introducing technologies for hydromechanization of mining operations in the conditions of the Kryvyi Rihiron ore basin is a topical issue. The methods. Using experimental installations conduct experiments on the destruction of layers of martite ores, gradually increasing the water pressure and determine the qualitative fractional yield of raw materials. Mathematical processing of the results obtained and the construction of dependencies based on experiments. Findings. Showing of the sequence of the experiment, the creation of summary tables with the results and the construction of illustrated graphs is the result of a study of determining the yield of fractional material during the destruction of ores by water jets. The originality. Experiments have shown that the yield of the ore fraction during their destruction using the hydro fracture method depends both on the water pressure and on the stratification of the ores. Ores that break down along the layer are more prone to overgrinding, and ores that break into a cross are less likely to. Therefore, the output of fractions during the destruction of layers of martite ores in some values can be controlled. Practical implementation. The development of floodingdeposits of rich iron ores by classical, unsuitable methods is accompanied by a large number of losses of ore raw materials or the impossibility of developing the deposit, because an alternative to the classical drilling and blasting method of destruction of a massif of rock is proposed technology of hydromechanization.The use of borehole hydraulic mining technology will allow the use of water flows from drainage wells or a sump for the safe, non-explosive destruction of the massif. This will increase the safety of mining operations, as well as reduce the seismic impact on the workings before the start of stope extraction.

TRANSFORMATION OF WORKING MODELS BEFORE AND AFTER THE COVID 19 PANDEMIC PROCESS: REMOTE WORKING MODEL
Authors: BÜLBÜL Yazgı
Published: August 2022

Since the World Health Organization declared a pandemic in March 2020, it has become mandatory to switch to a global remote/teleworking model in order to prevent the spread of the pandemic. This situation has become the traditional working model as the remote working model, which existed before the pandemic but started to be used in many sectors after the epidemic, became routine. The working from home model is valid for many sectors, but some sectors can only work face-to-face. Many companies that had to quickly switch to remote work have revealed various advantages and disadvantages for both employers and employees. With these advantages and disadvantages assessments, workers getting used to working from home, but feeling isolated and socializing in the office disappeared, the hybrid model aimed at maintaining the home-office balance started to be implemented as of 2021. Currently, many companies at the global level support the hybrid model, some continue to work in the office with the traditional model, and some continue to use the teleworking model.
Paying Them to Hate US: The Effect of U.S. Military Aid on Anti-American Terrorism, 1968-2018
Authors: Dimant Eugen , Krieger Tim , Meierrieks Daniel
Published: August 2022

Does U.S. military aid make the United States safer? Or does it have unintended consequences for U.S. security? By exploiting plausibly exogenous time variation in global levels of U.S. military aid and cross-national time-series variation in the relative importance of the various military aid programs for recipient countries, we provide causal estimates of the effect of U.S. military aid on anti-American terrorism for 174 countries in 1968-2018. Higher levels of military aid increase the likelihood of anti-American terrorism in recipient countries. At the sample mean, doubling U.S. military aid increases the risk of anti-American terrorism by 12.9 percentage points. Regarding potential transmission channels, more U.S. military aid leads to more corruption and exclusionary policies. That is, U.S. military aid results in anti-American terrorism by undermining institutions in recipient countries, thus creating anti-American resentment among those parts of the population that do not have access to the benefits from military aid.
Lighting application efficacy: A framework for holistically measuring lighting use in buildings
Authors: Durmus Dorukalp , Hu Wenye , Davis Wendy
Published: August 2022

Lighting consumes significant energy in buildings, but current measurements of lighting efficiency are inadequate in capturing the spatial and temporal effectiveness of light. The most widely used lighting energy efficiency measure, luminous efficacy, quantifies the amount of light generated by individual light sources. While luminous efficacy provides manufacturers and designers with a useful metric for quantifying the energy efficiency of individual lighting devices, it does not fully address the use of lighting in architectural spaces. Instead, application efficacy, the relationship between the electrical power consumed by lighting hardware and the amount of light that contributes to the visual perception of building occupants, must be measured. Here, we propose a framework for calculating lighting application efficacy (LAE) based on the primary pathway of light in architectural settings: the generation and emission of light from a luminaire, the travel of the light throughout the space and into occupants’ eyes, and the process of visual perception. The LAE framework will include the development of computational methods for estimating the proportion of emitted light that is directed to task areas and areas corresponding to occupants’ visual fields using ray-tracing lighting design software. Future modeling and validation work will quantify energy efficiency of buildings.
Comprehensive analysis of GINS subunits prognostic value and ceRNA network in sarcoma
Authors: Zhou Chuqiao , Chen Zhuoyuan , Xiao Bo , Xiang Cheng , Li Aoyu , Zhao Ziyue , Li Hui
Published: August 2022

Background: The GINS complex, composed of GINS1/2/3/4 subunits, is an essential structure of Cdc45-MCM-GINS (CMG) helicase and plays a vital role in establishing the DNA replication fork and chromosome replication. Meanwhile, GINS genes have been associated with the poor prognosis of various malignancies. However, the abnormal expression of GINS genes and their diagnostic and prognostic value in sarcomas (SARC) remain unclear.

Methods: Oncomine, Gene Expression Profiling Interactive Analysis (GEPIA), Kaplan-Meier Plotter, Cancer cell line encyclopedia (CCLE), The University of Alabama at Birmingham Cancer Data Analysis Portal (UALCAN), R studio, and Tumor Immune Estimation Resource (TIMER) were used to analyze the expression profiles, prognostic value, biological function, ceRNA, and immune infiltration associated with GINS genes in sarcomas.

Results: We found that GINS1/2/3/4 genes exhibited significantly upregulated transcription levels in SARC samples compared to non-tumor tissues and exhibited high expression levels in sarcoma cell lines. In addition, SARC patients with increased expression levels of GINS1/2/3/4 showed poorer survival rates. Immune infiltration analysis showed that GINS subunits were closely associated with the infiltration of immune cells in sarcomas.

Conclusion: Our research identified GINS subunits as potential diagnostic and prognostic biological targets in SARC and elucidated their underlying effects in the genesis and progression of SARC. These results may provide new opportunities and research directions for targeted sarcoma therapy.

Published: August 2022

As The effect of iron oxide nanoparticles (IONPs) on the anaerobic co-digestion (AD) of olive mill wastewater and chicken manure was investigated. In mesophilic conditions, biogas yield, methane (CH4) content, the removal efficiency of TS, VS., acidification and hydrolysis percentage, and contaminant removal efficiency were investigated. Supplementing AD with IONPs at a concentration of 20 mg/g VS. > IONPs and INOPs >30 mg/g VS. causes an inhibitor impact on biogas, methane generation, and hydrolysis. Furthermore, implantation with 20–30 mg of IONPs/kg VS. has induced an equivalent favorable impact, with hydrolysis percentages reaching roughly 7.2%–15.1% compared to the control test, in addition to a 1.3%–4.2% enhancement in methane generation yield. The maximum acidification concentration after five days of the incubation of 1,084, 9,463, and 760 g/L was attained with IONPs dosages of 25, 30, and 20 mg/g VS., respectively, compared to 713 g/L obtained with the control test. The results have illustrated that supplementing AD with a specific concentration of IONPs (20–30 mg/g VS.) has a significant effect and enhances the inhibitor removal efficiency, most possibly due to the small surface area of IONP particles. The resultant increase in the active surface area enhances the enzyme diffusion within the substrate. This study provides new data specifying the enhancement of iron oxide nanoparticles (IONPs) and identifies the impact of IONP doses at various concentrations on the AD of olive mill wastewater and chicken waste.
Nanoscale metal–organic frameworks as photosensitizers and nanocarriers in photodynamic therapy

Published: August 2022

Photodynamic therapy (PDT) is a new therapeutic system for cancer treatment that is less invasive and offers greater selectivity than chemotherapy, surgery, and radiation therapy. PDT employs irradiation light of known wavelength to excite a photosensitizer (PS) agent that undergoes photochemical reactions to release cytotoxic reactive oxygen species (ROS) that could trigger apoptosis or necrosis-induced cell death in tumor tissue. Nanoscale metal–organic frameworks (NMOFs) have unique structural advantages such as high porosity, large surface area, and tunable compositions that have attracted attention toward their use as photosensitizers or nanocarriers in PDT. They can be tailored for specific drug loading, targeting and release, hypoxia resistance, and with photoactive properties for efficient response to optical stimuli that enhance the efficacy of PDT. In this review, an overview of the basic chemistry of NMOFs, their design and use as photosensitizers in PDT, and as nanocarriers in synergistic therapies is presented. The review also discusses the morphology and size of NMOFs and their ability to improve photosensitizing properties and localize within a targeted tissue for effective and selective cancer cell death over healthy cells. Furthermore, targeting strategies that improve the overall PDT efficacy through stimulus-activated release and sub-cellular internalization are outlined with relevance to in vitro and in vivo studies from recent years.

Characterization of cardiovascular tissue geometry and mechanical properties of large animal models is essential when developing cardiovascular devices such as heart valve replacements. These datasets are especially critical when designing devices for pediatric patient populations, as there is often limited data for guidance. Here, we present a previously unavailable dataset capturing anatomical measurements and mechanical properties of juvenile Yorkshire (YO) and Yucatan (YU) porcine main pulmonary artery (PA) and pulmonary valve (PV) tissue regions that will inform pediatric heart valve design requirements for preclinical animal studies. In addition, we developed a novel radial balloon catheter-based method to measure tissue stiffness and validated it against a traditional uniaxial tensile testing method. YU piglets, which were significantly lower weight than YO counterparts despite similar age, had smaller PA and PV diameters (7.6–9.9 mm vs. 10.1–12.8 mm). Young’s modulus (stiffness) was measured for the PA and the PV region using both the radial and uniaxial testing methods. There was no significant difference between the two breeds for Young’s modulus measured in the elastic (YU PA 84.7 ± 37.3 kPa, YO PA 79.3 ± 15.7 kPa) and fibrous regimes (YU PA 308.6 ± 59.4 kPa, YO PA 355.7 ± 68.9 kPa) of the stress-strain curves. The two testing techniques also produced similar stiffness measurements for the PA and PV region, although PV data showed greater variation between techniques. Overall, YU and YO piglets had similar PA and PV diameters and tissue stiffness to previously reported infant pediatric patients. These results provide a previously unavailable age-specific juvenile porcine tissue geometry and stiffness dataset critical to the development of pediatric cardiovascular prostheses. Additionally, the data demonstrates the efficacy of a novel balloon catheter-based technique that could be adapted to non-destructively measure tissue stiffness in situ.

Hydraulic fracturing is widely implemented in the exploration of marine shale gas. Affected by various geological and engineering factors, gas production after stimulation is not always satisfactory. To reveal the influential effect of multiple factors, laboratory hydraulic fracturing experiments are performed on Longmaxi marine shales by considering key parameters (deviatoric stress, confining pressure, pumping rate, fracturing fluid type, and bedding angle). The variation of breakdown pressures and the characteristics of hydraulic fractures are recorded and analyzed. The results show that the breakdown pressure increases with increasing deviatoric stress, confining pressure, pumping rate, and viscosity of the fracturing fluid. As the bedding angle varies from 0° to 90°, the breakdown pressure declines first and increases again. Furthermore, parameter sensitivity analysis indicates that geological factors (confining pressure, bedding angle, and deviatoric stress) would largely determine the breakdown pressure, while engineering factors (pumping rate, fracturing fluid type) could only affect it to a lesser extent. Computed tomography measurements show that natural fractures, originating from tectonic shear failure, could possess greater width than tension-dominated hydraulic and bedding fractures. Statistical analysis shows that the length of the hydraulic fractures alone is only approximately 150 mm. However, the fully activated natural and/or bedding fractures could help substantially increase the total fracture length to 600 mm. Low deviatoric stress, low confining pressure, low viscous slick-water, and high bedding angle are conducive to activating natural and bedding fractures and forming a complex fracture network. The aforementioned findings are valuable for the optimal design of field hydraulic fracturing.

Published: August 2022

In competitive sports, the training load is close to the human physiological limit, which will inevitably lead to exercise-induced fatigue. If fatigue cannot be recovered in time, it will eventually lead to excessive training and affect sport performance. Therefore, fatigue has become an important part of the physical function assessment for athletes. This paper will review animal models of long-term exercise-induced fatigue, modeling schemes of mice under treadmill and swimming training, phenotypes of long-term exercise-induced fatigue (e.g., nervous system damage, myocardial cell damage, bone mineral density changes, and skeletal muscle damage), and fatigue indicators. The relationship between physiological indicators and biomarkers and long-term exercise-induced fatigue is analyzed to promote exercise-induced fatigue monitoring. This paper attempts to provide a reference for the selection of animal models of long-term exercise-induced fatigue and provide a new theoretical basis for medical supervision and recovery of exercise-induced fatigue.
New momentum for data, government investment in technology, and high-quality urban development in the yellow river basin

Published: August 2022

The “Great Protection, Great Governance” strategy requires efficient environmental protection in the Yellow River Basin (YRB), enhancement of transformation between the old and new momentums, and high-quality development (HQD) of the region. This research explores the impact of the new momentum for data and government investment in technology on the HQD level of 62 cities in the YRB. The data used in this paper are collected from 2008 to 2020. We construct the index system and apply the analytic hierarchy process and entropy value method to calculate the HQD level of 62 cities in the YRB. We also construct the spatial Durbin model to investigate the influence mechanism of the above factors on the HQD of cities in the YRB and their effects from the perspectives of the new momentum for data and government investment in science and technology. According to the research results, the level of high-quality urban development of the YRB exhibits a stable increase in time series and an overall spatial distribution pattern of “higher in the east-west and lower in the middle” and “higher in the south and lower in the north”. The new momentum for data and government investment in technology significantly contribute to the HQD of cities in the YRB, with significant spatial spillover effects. The new momentum for data and government investment in technology have a positive impact on the HQD of a city and the neighboring cities. Meanwhile, the level of human capital, government intervention, scientific and technological (S&T) innovation, and openness contribute significantly to high-quality urban development. The government and policymakers should focus on the prominent role of new momentum for data and government investment in technology and design long-term feasible strategies to improve the high-quality urban development in a new stage.
