Abstract
Stent-related granulation tissue hyperplasia is a major complication that limits the application of stents in airways. In this study, an arsenic trioxide-eluting electrospun nanofiber-covered self-expandable metallic stent (ATO-NFCS) was developed. Poly-L-lactide-caprolactone (PLCL) was selected as the drug-carrying polymer. Stents with two different ATO contents (0.4% ATO/PLCL and 1.2% ATO/PLCL) were fabricated. The in vitro release in simulated airway fluid suggested that the total ATO release time was 1 d. The growth of human embryonic pulmonary fibroblasts (CCC-HPF-1), normal human bronchial epithelial cells and airway smooth muscle cells was inhibited by ATO. When embedded in paravertebral muscle, the nanofiber membrane showed good short-term and long-term biological effects. In an animal study, placement of the ATO-NFCS in the trachea through a delivery system under fluoroscopy was feasible. The changes in liver and kidney function 1 and 7 d after ATO-NFCS placement were within the normal range. On pathological examination, the heart, liver, spleen, lungs and kidneys were normal. The effectiveness of the ATO-NFCS in reducing granulation tissue hyperplasia and collagen deposition was demonstrated in the rabbit airway (n = 18) at 4 weeks. The present study preliminarily investigated the efficacy of the ATO-NFCS in reducing granulation tissue formation in the trachea of rabbits. The results suggest that the ATO-NFCS is safe in vivo, easy to place, and effective for the suppression of granulation tissue formation.

Published: August 2020

Abstract
Sustainable approaches capable of tracking status, trends and drivers of lake water balances in complex, remote landscapes are needed to inform ecosystem stewardship and water-security actions. At the Peace-Athabasca Delta (Alberta, Canada), a globally recognized freshwater floodplain landscape, concerns about water-level drawdown and multiple potential stressors have prompted need to improve knowledge of lake water balances and establish a lake monitoring program. Yet, the delta’s remoteness and dynamic nature present challenges to these goals. Here we use over 1000 measurements of water isotope composition at ∼60 lakes and 9 river sites during the spring, summer and fall of five consecutive years (2015–2019) to elucidate patterns in lake water balance over time and space, the influential roles of evaporation and river floodwaters, and relations with meteorological conditions and river water levels. Calculation of evaporation-to-inflow ratios using a coupled-isotope tracer approach, displayed via generalized additive models and geospatial ‘isoscapes’, reveal strongly varying lake water balances. Results identify distinct areas vulnerable to lake-level drawdown, given the likelihood of continued decline in ice-jam flood frequency, longer ice-free season duration and reduced snowmelt runoff. Results also demarcate areas of the delta where lakes are more resilient to factors that cause drawdown. The former defines the Peace sector, which is influenced by floodwaters from the Peace River during episodic ice-jam flood events, whereas the latter describes portions of the active floodplain environment of the Athabasca sector which receives more frequent contributions of Athabasca River floodwaters during both spring ice-jam and open-water seasons. Efficiency of water isotope tracers to capture the marked temporal and spatial heterogeneity in lake water balances during this 5 year time span, and their diagnostic responses to key hydrological processes, serves as a foundation for ongoing lake monitoring, an approach readily transferable to other remote and dynamic lake-rich landscapes.
Logistic and θ-logistic models in population dynamics: general analysis and exact results
Authors: Cufaro Petroni Nicola , De Martino Salvatore , De Siena Silvio 
Published: August 2020

Abstract
Stochastic logistic and θ-logistic models have many applications in biological and physical contexts, and investigating their structure is of great relevance. In the present paper we provide the closed form of the path-like solutions for the logistic and θ-logistic stochastic differential equations, along with the exact expressions of both their probability density functions and their moments. We simulate in addition a few typical sample trajectories, and we provide a few examples of numerical computation of the said closed formulas at different noise intensities: this shows in particular that an increasing randomness—while making the process more unpredictable—asymptotically tends to suppress in average the logistic growth. These main results are preceded by a discussion of the noiseless, deterministic versions of these models: a prologue which turns out to be instrumental—on the basis of a few simplified but functional hypotheses—to frame the logistic and θ-logistic equations in a unified context, within which also the Gompertz model emerges from an anomalous scaling.
Exposure to cough aerosols and development of pulmonary COVID-19
Authors: Vanden Driessche Koen , Nestele Jeremy , Grouwels Jeroen , Duval Els LIM 
Published: August 2020

Abstract
We hypothesized that most patients with severe pulmonary COVID-19 were exposed to cough aerosols. Among patients that were almost 100% certain which person infected them, only 14 out of 38 overall, and 9 out of 25 hospitalized patients requiring supplemental oxygen, were infected by someone who coughed, which did not support our hypothesis. Talking, especially with a loud voice, could be an alternative source generating SARS-CoV-2 aerosols. Further research is needed to determine how SARS-CoV-2 spreads. Avoiding to talk when you are not wearing your mask and not talking with a loud voice, ‘voice etiquette’, could be other public health interventions worthwhile exploring.
The Effects of Climate Change on Snow Leopards at the Hengduan Mountain Region
Authors: Shen Qiushi 
Published: August 2020

Abstract
Snow leopard is one of the top predators and umbrella species of Hengduan Mountain (HM) region. Conserving snow leopard is vital in preserving this biodiversity hot spot. Climate change (CC) is imposing negative influences on snow leopard populations. This research combines and analyses recent research papers on this topic. It turns out that snow leopards are generally influenced by CC in three ways. Firstly, climate change enables forest to move to higher elevation to occupy grasslands, the main habitats of snow leopards. Therefore, snow leopard habitat shrinks and suffers greater fragmentation. Secondly, climate change makes grasslands more vulnerable to degradation, thus threatening preys of snow leopards. Thirdly, CC causes leopards to move to previous snow leopard habitats. As a result, there are risks of competition between snow leopards and leopards. This research appeals for more observation to better analyse snow leopard’s response to climate change.

Published: August 2020

Abstract
Water systems have complex constituent interactions requiring development and evaluation of management amidst uncertainties of climate and constrained natural resources. This paper outlines water resources planning is developed based on the current water resources availability and demand situation by using Water Evaluation and Planning (WEAP) model to evaluate an existing water balance of the Bago River Basin, Myanmar. The study area is approximately 2,660 km2 and the Bago River is the main water resources for demand purposes of Bago township with gauging stations. The water resources planning from upstream of Bago river to Bago Township was calibrated and vilified with quantitative statistics (coefficient of determination, R2; Nash-Sutcliffe efficiency, NSE and Root mean square error, RMSE). The calibrated results fitted to the observed data during 2011-2015 with R2 = 0.99, NSE = 0.88, and RMSE = 24 m3/s, and validated in 2016-2018 with R2 = 0.99, NSE = 1, and RMSE = 10 m3/s, respectively. The results showed the model advanced through WEAP is highly proficient and exhibited great performance to manage available water resources and indicated that currently the basin has sufficient water to meet the water demands in the basin.

Published: August 2020

Abstract
The contradiction between economic development and pollution control is becoming increasingly prominent, which is a huge problem that China’s economic development transformation must face and solve at this stage. Among them, the governance of haze is the crux because of its great impact on health. The game behavior of haze governance involves many subjects. After considering the specific situation of the game in reality, this paper constructs a mixed strategy model of multi stakeholders, including the central government, local government, enterprises and the public. In addition to the direct participation of local governments and enterprises in the game, the central government and the public indirectly participate in the final game results through supervision and public opinion. Based on the analysis of the game results, in order to better control the haze and achieve green development, enterprises should strengthen environmental self-discipline, local government and central government should cooperate effectively, and the public should actively participate in it to form a strong influence of public opinion.

Abstract
With the refinement of water environment management in the basin, the work of Water Pollutant Source List (WPSL) has been carried out. The article separately calculates the pollution load of point sources and area sources, among which point sources include industry sources, sewage treatment plants, large-scale livestock and poultry farms, area sources include urban runoff, rural life, agricultural planting, and rural livestock and poultry farming. Pollutants include chemical oxygen demand (COD), ammonia nitrogen (NH3-N), total nitrogen (TN), and total phosphorus (TP). Based on a certain spatial induction method, the pollution load is assigned to a grid of 1km×1km, and a high-resolution water pollution source list is established, which provides a refined basic database for environmental management.
Study on space environment safety based on satellite collision
Authors: Hongqiang Sun , Zhanyue Zhang 
Published: August 2020

AbstractIn order to avoid collision with SpaceX’s Starlink44 satellite, the European space agency (ESA) said on September 2, 2019 that it fired the thrusters of the Aeolus satellite to avoid collision. In this paper, the collision probability of two space objects is analyzed. In addition, considering the crowded space environment in the future, the number of collisions in a certain period of time was simulated. Meanwhile, compared with the number of possible collisions within 365 days of the existing space target and the number of possible collisions after the addition of Starlink satellite group. The result shows that the future space environment will be much more crowded than expected. On this basis, some reasonable suggestions are put forward for the future space development to ensure the safety and reliability of the future space.

Authors: Chen Wenhua , Xia Nian 
Published: August 2020

AbstractWith the increasing of social pro-environmental preference, people receive various “green” signals that influence their consumption decisions. The purpose of our work is to establish a green consumption behavior research model based on social pro-environmental preference. We explore the three expressions forms (regulation, price and public opinion) of social pro-environmental preference, and their expressions content in consumer green purchase and green disposal, as well as the influence mechanism on green consumption. The research results show that the regulatory expression of pro-environmental preference (energy-efficient certification), and the price expression of pro-environmental preference (price discount) have a significant positive effect on green disposal behaviors; environmental online public opinion has a significant positive impact both on green product purchases and green disposal behavior.

Published: August 2020

Abstract
The prediction results of the compressive strength of high-performance concrete (HPC) based on intelligent algorithms are seriously affected by the input variables. In this study, the Random Forest algorithm (RF) is introduced to optimize the number of input variables by evaluating the importance of influencing factors, and then predict the 28-day compressive strength through Random Forest Regression. The results show that this method is effective for the optimization of input variables, and when the parameters are set within a reasonable range, better prediction results can be obtained than non-variable optimization.

Abstract
In this paper, Al-based composites used for hydrogen production have been prepared by ball milling process. In order to reduce the cost of Al-based composites, we prepared micro/nano sized Al2O3 with the by-product of Al-based composites hydrolysis reaction. X-ray diffraction (XRD), scanning electron microscopy (SEM), and Mastersizer 2000 size analyzer are used for the analysis of the samples. The results show that Al2O3 phase is formed after the by-product milling for 4h and the by-product milled for 6h can reach micro/nanometer level. It is beneficial to reduce the cost of Al-based composites, which can promote the wide application of Al-based composites in the field of hydrogen production.
Study on Mathematical Model for Condensation Heat Transfer in Two-phase Closed Thermosyphon
Authors: Ren Bin , Pu Zhe , Du Yannan , Tang Xiaoying , Yang Yuqing , Lu Hongliang 
Published: August 2020

Abstract
The two-phase closed thermosyphon is a special heat pipe utilizing gravity instead of capillary force to return the liquid to evaporator. Some assumptions for Nusselt model are not true in the condenser section, resulting in the complexity of condensation. In this paper, a numerical model based on Nusselt’s model is developed considering vapour-liquid interfacial shear stress. The distributions of local parameters such as shear stress, liquid film thickness are analysed. The variation of average heat transfer coefficient with temperature difference is displayed. And the average heat transfer coefficients predicted by numerical model are compared with values calculated from other references. The results show that both the shear stress and liquid film thickness increase as condensation proceeds. But the growth rate decreases along the axial direction. The average heat transfer coefficients predicted by this model is lower than that calculated by Nusselt’s correlation especially at higher heat load, indicating that shear stress really reduces the heat transfer performance.

Published: August 2020

Abstract
The use of Unmanned Aerial Vehicles and known under the generic name of drones is increasingly present in different economic sectors, due to the versatility they offer in solving specific problems. The specific problems to be solved, however, raise the need for the technical characteristics of the drones to be optimized according to the specific usage. In the case of drones used in technological processes in agriculture, they must offer a high autonomy, that can be increased by optimizing their weight. The paper proposes the study of the dynamics of the air flow according to the configuration of the drone rotor (2 and 3 rotor respectively) by numerical analysis methods for the further development of a drone that will be used in the phytosanitary treatment process of agricultural crops. The parameters evaluated and compared are the specific parameters for characterizing the airflow: velocity and relative pressure (at different nacelle’s section, both in horizontal and vertical directions). The obtained results show that the most constant, dense and homogeneous velocity field was obtained from the 3-blade configuration of the rotor.
Aspects of creativity management in the Romanian industry and doctoral research
Authors: Moraru G M , Popescu L G 
Published: August 2020

Abstract
Creativity management is an extremely vast field, which has preoccupied us for many years. In this paper we present some aspects of the junction between creativity management in academic research and creativity management in industry. Our aim was to compare how creativity management influences the results of the PhD students’ researches with the way in which creativity management in industry influences the organizational performances and competitiveness. The research based on questionnaires was carried out in parallel in technical and economic faculties in Romania, as well as in industrial organizations. Even if the variables analysed on the two samples of respondents are different, because they have different aims and interests regarding the use of creativity management, we have made comparisons between the two sets of variables and proved that the impact of creativity management in PhD students’ research is high, but the impact of creativity management in Romanian industry is low.

Published: August 2020

Abstract
The purpose of this study is to review literature on topics of performance and co-creation. The study has two premises: performance includes economic and behavioural aspects; co-creation produces direct and indirect effects on performance. In order to validate these two, we took into consideration all studies available on WoS platform. Applying different selection criteria, we obtained a sample of 14 studies published between 2016 and 2020. Through observation, comparison and logic deductions we were able to appreciate the authors` interest in identifying new research directions. Thus, we show that: a) co-creation has a direct impact on performance, competitiveness and value for stakeholders; in this context, performance is regarded as a multidimensional concept with wide implications in various fields such as management, financial, marketing, innovation etc.; b) co-creation has an indirect influence on performance through elements like: brand, product-service systems and cross-sector partnerships. These aspects are empirically validated in different context. The results of our research prove to be useful from two points of view: theoretical (because the study presents in an authentic manner the state of the knowledge on performance and co-creation) and methodological (because it offers support to all those interested in finding new research directions).
