Authors: Gao Junli , Shao Chaofeng , Chen Sihan , Zhang Xiaotong 
Published: September 2021

ABSTRACT
Three sustainable development sub-indicators were established along with 49 indicators of sustainable development at the provincial level. We collected data for the key years of 2010, 2015, and 2018 and evaluated the sustainable development level of 31 provinces in China by using the best and worst value improved equal-weight TOPSIS method. With spatial autocorrelation and hotspot analysis, the spatial characteristics of the sustainable development level were studied. Grey correlation analysis and the offset degree index were also used to find out which indicators should be of most concern to improve the level of sustainable development. The results showed the following. (1) The level of sustainable development of China’s provinces is increasing, but there is a decrease from east to west. (2) In terms of sustainable development, the gap between the four major economic regions is narrowing. (3) The overall sustainable development level is highly consistent with the mainstream green development and the human development index, indicating that exploiting the driving force behind developing and improving the quality of development is the key to China’s sustainable development strategy. (4) Different measures should be taken to promote the realization of Sustainable Development Goals in different areas.
Theoretical study on the favored alpha-decay half-lives of deformed nuclei
Authors: Hassanzad M. , Ghodsi O.N. 
Published: September 2021

Abstract
A systematic study on the α-decay half-lives of nuclei in the range

is performed by employing various versions of proximity potentials. To obtain more reliable results, deformation terms are included up to hexadecapole (

) in the spherical-deformed nuclear and Coulomb interaction potentials. First, the favored α-decay processes in this region are categorized as even-even, odd A, and odd-odd nuclei. Second, they are grouped into two transitions: ground state to ground state and ground state to isomeric states. Owing to the comparison of their root-mean-square deviations (RMSD's),

and

have the lowest values and better reproduce experimental data. Moreover, by considering preformation probability within the cluster formation model, the results validate the significant reduction in root-mean-square deviations obtained for different versions of proximity. Hence, the deviation between the calculated and experimental data is detracted.
Thermodynamic model of the activity of the comet 103P/Hartley*
Authors: Wesołowski Marcin 
Published: September 2021

Abstract
The paper presents three processes related to the dynamics of cometary particles. The following thermodynamic mechanisms were taken into account: quiet sublimation, emission of cometary matter via jet and migration of particles on the surface of the comet 103P/Hartley. Based on the first two mechanisms, the maximum particle size that can be lifted into the coma was determined. Additionally, in the case of a jet, the angle at which it is emitted from inside the cometary nucleus was determined. However, in the case of migration, the maximum width of individual belts within which a given particle can move was determined. In the context of the discussed mechanisms related to the activity of comet 103P/Hartley, the coefficient of friction and the structure of the solid or porous particles are of key importance.

Authors: Zhang Yan-Jun , Li Yan-Zuo , Cheng Jun , Yan Yi-Hua 
Published: September 2021

Abstract
Radio frequency interference (RFI) will pollute the weak astronomical signals receivedby radio telescopes, which in return will seriously affect the time-domain astronomical observation and research. In this paper, we use a deep learning method to identify RFI in frequency spectrum data, and propose a neural network based on Unet that combines the principles of depthwise separable convolution and residual, named DSC Based Dual-Resunet. Compared with the existing Unet network, DSC Based Dual-Resunet performs better in terms ofaccuracy, F1 score, and MIoU, and is also better in terms of computation cost where the model size and parameter amount are 12.5% of Unet and the amount of computation is 38%ofUnet. The experimental results show that the proposed network is a high-performance and lightweight network, and it is hopeful to be applied to RFI identification of radio telescopes on a large scale.
Application of thermal gravimetric analysis and comparison of polyethylene films before and after exposure in various chemical solutions
Authors: Kojnoková T , Markovičová L , Nový F 
Published: September 2021

Abstract
In this paper, there are published experimental results of research in the field of polymers. The thermal analysis conveys information about changes in material effected by the melting of the material. The investigated material is low-density polyethylene (LD – PE). The LD – PE films were exposed to aggressive media with different values of potencia hydrogeni (pH). The experiment aims to apply thermal gravimetric analysis (TGA), one of the methods of thermal analysis. TGA monitors the weight of polyethylene films as a function of temperature. Original LD – PE film and the effect of media is evaluated based on TGA and evaluation of the surface morphology (macrostructure) after exposure. The largest weight loss is noticed in the original film without the influence of media. At 200 °C, the wax products are released from the material. During thermal analysis is observed a weight loss of up to 1 mg in the investigated film samples. LD – PE film after the effect of Coca-Cola has the highest decrease in mass and the most changed its macrostructure. LD – PE film after effect of Saponate has the lowest decrease in mass and its macrostructure is almost the same as the original LD – PE film after production technology.
The mechanical properties of coatings sprayed by electric arc for use in coal power plants
Authors: Šulcová P , Houdková Š , Duliškovič J 
Published: September 2021

Abstract
The components in coal power plants such as fire sides in boilers, preheaters, or heat exchangers are significantly mechanically and chemically stressed. The main stress originates from high temperature corrosion caused by the aggressive atmosphere inside the boiler, but other influences such as erosion and abrasion by coal and flying ash, heat shocks, etc. also have significant negative effect. One of the options for increasing the service life and improving the utility properties of these components is a thermal spray coating. Because the disassembly of these components is impossible, the mobile TWAS deposition technology was used. In this paper, different types of TWAS-sprayed coatings suitable for application in such environment are compared and evaluated. Two types of coating materials were evaluated, FeCr-based ones and NiCr-based ones, in terms of microstructure and mechanical properties such as hardness, adhesion, abrasion and erosion resistance. The SEM microscopy evaluation was used to evaluate the wear mechanism. It was found that the coatings with lower hardness but higher toughness resist the solid particle erosion better than hard but more brittle coatings. The experiences with the application of these coatings in selected areas on the fire side inside the boiler in the coal power plant are briefly reported.

Published: September 2021

Abstract
In the present study, additively-manufactured (AM) specimens from 316L steel were investigated. The AM method used was Direct Energy Deposition (DED) where powder is fed continuously to a melt pool and is completely melted by high power laser. The melt pool rapidly solidifies on and beneath the substrate surface. To protect it from oxidation during deposition, argon is used as a shielding gas and is blown continuously to the melt pool. The DED process generates structures with minimum pores. 316L austenitic stainless steel was chosen for the experiments in order to avoid dealing with complex phase transformations during deposition. Four 316L powders supplied by four different companies were used and differences in the mechanical properties of the builds were examined. The process parameters were the same for each powder. There a number of studies on Selective Laser Melting (SLM) which explore the effects of powder properties on final mechanical properties of the builds. The underlying idea is to select a powder from a particular supplier to meet the customer required properties.
Investigation of thermal stability of Si0.7Ge0.3Si stacked multilayer with As ion-implantation

Published: September 2021

Abstract
The effect of As ion implantation on the stability of SiGe/Si multilayer was systematically studied. The atomic percentage of Ge in as-grown SiGe layer was 30% in this work. A thermally stable Si0.7Ge0.3/Si multilayer with As ion implantation was attained when the rapid thermal annealing (RTA) treatment temperature did not exceed 850 oC. Significant Ge diffusion was observed for the SiGe/Si multilayer with As ion implantation when the RTA temperature was 900 °C or above. However, minor Ge diffusion was attained for the SiGe/Si multilayer without As ion implantation when the RTA treatment temperature was 900 °C. Therefore, , compared with samples without As ion implantation, the stability window of the SiGe/Si multilayer with As ion implantation should be further reduced to 850 °C. As ion implantation plays a critical role in the stability of SiGe/Si multilayer, as it promotes the diffusion of Ge. Consequently, based on the stability of the SiGe/Si multilayer, the highest RTA treatment temperature of 850 °C is proposed for the gate-all-around (GAA) device fabrication process.

Authors: Wang Jun , Xu Ya-nan , Tang Long , Zhang Jing-shui , Li Zhen , Shao Ming-liang , Hu Long , Wang Xian-ping 
Published: September 2021

Abstract

Background
To investigate the effect of serum total bilirubin levels on blood pressure and its variability in patients with hypertension.

Methods
This study was a retrospective observational study. A total of 189 subjects were recruited from September 2019 to March 2020. All hypertensive patients were scheduled for ambulatory blood pressure and a 24-hour dynamic electrocardiography. Standard deviations of 24-hour systolic and diastolic blood pressure were used as blood pressure variability indicators. A multiple linear regression was used to analyze the relationship between total bilirubin serum levels and blood pressure variability in hypertensive patients.

Results
All patients were divided into 3 groups according to tertile values of total bilirubin: low (≤12.2 µmol/l, n = 64), moderate (12.3–16.7 µmol/l, n = 64), and high (&gt;16.8 µmol/l, n = 62) total bilirubin groups. Compared with low total bilirubin group, 24-hour mean systolic and diastolic blood pressure, 24-hour systolic blood pressure standard deviation, systolic blood pressure coefficient of variability, and 24-hour systolic blood pressure load were reduced in the moderate and high total bilirubin groups (all P &lt; 0.05). Multiple linear regression analysis showed that female (B = −1.408, P = 0.013), age (B = 0.043, P = 0.035), diabetes (B = 2.624, P &lt; 0.001), and moderate and high bilirubin grouping (B = −1.582, −3.079; both P &lt; 0.05) were influencing factors of 24-hour systolic pressure standard deviation. Serum total bilirubin levels had no effect on the standard deviation of 24-hour diastolic blood pressure(P &gt; 0.05).

Conclusions
In hypertensive patients, the total bilirubin serum level is an influencing factor for 24-hour systolic blood pressure variability.

Abstract
Striated muscle needs to maintain cellular homeostasis in adaptation to increases in physiological and metabolic demands. Failure to do so can result in rhabdomyolysis. The identification of novel genetic conditions associated with rhabdomyolysis helps to shed light on hitherto unrecognized homeostatic mechanisms. Here we report seven individuals in six families from different ethnic backgrounds with biallelic variants in MLIP, which encodes the muscular lamin A/C-interacting protein, MLIP. Patients presented with a consistent phenotype characterized by mild muscle weakness, exercise-induced muscle pain, variable susceptibility to episodes of rhabdomyolysis, and persistent basal elevated serum creatine kinase levels. The biallelic truncating variants were predicted to result in disruption of the nuclear localizing signal of MLIP. Additionally, reduced overall RNA expression levels of the predominant MLIP isoform were observed in patients’ skeletal muscle. Collectively, our data increase the understanding of the genetic landscape of rhabdomyolysis to now include MLIP as a novel disease gene in humans and solidifies MLIP’s role in normal and diseased skeletal muscle homeostasis.
Increased risk of diaphragmatic herniation following esophagectomy with a minimally invasive abdominal approach
Authors: Lee Adele Hwee Hong , Oo June , Cabalag Carlos S , Link Emma , Duong Cuong Phu 
Published: September 2021

Summary

Objective
Diaphragmatic herniation is a rare complication following esophagectomy, associated with risks of aspiration pneumonia, bowel obstruction, and strangulation. Repair can be challenging due to the presence of the gastric conduit. We performed this systematic review and meta-analysis to determine the incidence and risk factors associated with diaphragmatic herniation following esophagectomy, the timing and mode of presentation, and outcomes of repair.

Methods
A systematic search using Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines was performed using four major databases. A meta-analysis of diaphragmatic herniation incidence following esophagectomies with a minimally invasive abdominal (MIA) approach compared with open esophagectomies was conducted. Qualitative analysis was performed for tumor location, associated symptoms, time to presentation, and outcomes of postdiaphragmatic herniation repair.

Results
This systematic review consisted of 17,052 patients from 32 studies. The risk of diaphragmatic herniation was 2.74 times higher in MIA esophagectomy compared with open esophagectomy, with pooled incidence of 6.0% versus 3.2%, respectively. Diaphragmatic herniation was more commonly seen following surgery for distal esophageal tumors. Majority of patients (64%) were symptomatic at diagnosis. Presentation within 30 days of operation occurred in 21% of cases and is twice as likely to require emergent repair with increased surgical morbidity. Early diaphragmatic herniation recurrence and cardiorespiratory complications are common sequelae following hernia repair.

Conclusions
In the era of MIA esophagectomy, one has to be cognizant of the increased risk of diaphragmatic herniation and its sequelae. Failure to recognize early diaphragmatic herniation can result in catastrophic consequences. Increased vigilance and decreased threshold for imaging during this period is warranted.

Abstract
Cannabis use alters sperm DNA methylation, but the potential reversibility of these changes is unknown. Semen samples from cannabis users and non-user controls were collected at baseline and again following a 77-day period of cannabis abstinence (one spermatogenic cycle). Users and controls did not significantly differ by demographics or semen analyses. Whole-genome bisulfite sequencing identified 163 CpG sites with significantly different DNA methylation in sperm between groups (P &lt; 2.94 × 10−9). Genes associated with altered CpG sites were enriched with those involved in development, including cardiogenesis and neurodevelopment. Many of the differences in sperm DNA methylation between groups were diminished after cannabis abstinence. These results indicate that sustained cannabis abstinence significantly reduces the number of sperm showing cannabis-associated alterations at genes important for early development.
Major Reforms in Electricity Pricing: Evidence from a Quasi-Experiment
Authors: Labandeira Xavier , Labeaga José M , Teixidó Jordi J 
Published: September 2021

Abstract
The global energy mix and cost structure of the power industry are experiencing a redefinition. Many countries are revamping electricity-pricing systems to guarantee fixed-cost recovery, often by raising the fixed charge of two-part tariff schemes. However, a key assumption of two-part tariff schemes and associated fixed-cost recoveries is that consumers discriminate fixed from marginal costs. We conduct a quasi-experiment with data from a major electricity price reform recently implemented in Spain and find robust evidence indicating that consumers fail to distinguish between fixed and marginal costs. As a result, policymakers are not achieving the goal of cost recovery.

SUMMARYThe brutal onset of seismicity offshore Mayotte island North of the Mozambique Channel, Indian Ocean, that occurred in May 2018 caught the population, authorities and scientific community off guard. Around 20 potentially felt earthquakes were recorded in the first 5 d, up to magnitude Mw 5.9. The scientific community had little pre-existing knowledge of the seismic activity in the region due to poor seismic network coverage. During 2018 and 2019, the MAYOBS/REVOSIMA seismology group was progressively built between four French research institutions to improve instrumentation and data sets to monitor what we know now as an on-going exceptional submarine basaltic eruption. After the addition of 3 medium-band stations on Mayotte island and 1 on Grande Glorieuse island in early 2019, the data recovered from the Ocean Bottom Seismometers were regularly processed by the group to improve the location of the earthquakes detected daily by the land network. We first built a new local 1-D velocity model and established specific data processing procedures. The local 1.66 low VP/VS ratio we estimated is compatible with a volcanic island context. We manually picked about 125 000 P and S phases on land and sea bottom stations to locate more than 5000 events between February 2019 and May 2020. The earthquakes outline two separate seismic clusters offshore that we named Proximal and Distal. The Proximal cluster, located 10 km offshore Mayotte eastern coastlines, is 20–50 km deep and has a cylindrical shape. The Distal cluster start 5 km to the east of the Proximal cluster and extends below Mayotte's new volcanic edifice, from 50 to 25 km depth. The two clusters appear seismically separated, however our data set is insufficient to firmly demonstrate this.
