Published: August 2021

Abstract
One of the challenges that China currently faces is how to reduce the emissions of the water pollution. However, the study of water pollution convergence has certain policy significance for controlling the emissions of water pollution. This article firstly uses chemical oxygen demand（COD）and ammonia nitrogen（NH3-N）as indicators of water pollution. Due to the obvious spillover effect of water in space, this article adds spatial effect to the convergence model. Based on panel data of 30 provinces and cities from 2006 to 2017, this article uses a dynamic spatial Dubin model to analyze the convergence of water pollution emission intensity to address the endogenous problem in the model. The empirical results of this paper show that there is absolute β-convergence and conditional β-convergence in the intensity of water pollution emissions. The spatial autocorrelation test shows that there is a positive spatial autocorrelation of water pollution emissions, which means that the pollution emissions in neighboring areas will affect the emissions in the local area. The industrial structure has a certain promoting effect on the emission of water pollution, which means that adjusting the industrial structure and alleviating the structure of the secondary industry is the trend of future development. Economic growth can curb the emissions of water pollution. The influences of urbanization and foreign investment on the emissions of the two pollutants are inconsistent, and policies can be formulated according to local conditions in the future.

Published: August 2021

Abstract
The aim of the present work is to investigate the doping effect of Zn metal ions on hydroxyapatite for different concentrations (0.2, 0.4, 0.6, and 0.8). The samples for the pure and Zn doped HAp are synthesized by wet chemical precipitation method. The properties and the particle size are identified by using XRD. The functional bands of PO, CO and OH are analyzed through FTIR and the surface morphology and particle shapes are studied through SEM. The elemental analysis such as zinc, calcium and phosphates are analyzed by EDAX. All the designed elements are studied and confirm the (Ca+Zn)/PO ratio is nearly 1.67 and no other elements were identified in this study. The morphological particles of needle shape and the nanoscale particle size and shapes are studied by using TEM. The electrical conductivity of the synthesized ZnHAp ceramic is mainly related to width of the channel and the polarizability. The dielectric loss and nyquist plots were studied by using impedance spectroscopy.

Abstract
Graphene oxide (GO) or reduced-GO offer excellent mechanical, electrical and chemical properties. Their nanocomposites have been increasingly explored for attractive applications in diverse fields. However, due to the flexible feature and weak interlayer interactions of GO sheets, flexural mechanical properties of GO-based composites especially for the bulk materials are largely restrained, which would hinder their use in real situations. Here inspired by amorphous/crystalline heterophase features within nacreous platelets, we construct a centimetre-sized GO-based bulk, the building blocks of which consist of crystalline GO and amorphous/crystalline MnO2 phases adhered by polymer-based crosslinkers. The GO/MnO2 heterophase layers are stacked and hot-pressed with further crosslinking between the layers to form bulk artificial nacre. The resultant GO/MnO2-based layered (GML) bulk exhibits the highest flexural strength (up to 203.4 MPa) among all of GO-based bulk materials. Moreover, an excellent fracture toughness, a strong impact resistance and light weight are also achieved. Mechanical and simulation analyses corroborate that the highly ordered heterophase structure together with complex crosslinking interactions across multiscale interfaces, lead to superior mechanical properties. We expect that these results provide interesting insights into the design of structural materials and allow the use of high-performance GO-based bulks in engineering and military applications.

Abstract
Background: Teenage pregnancy is an event known to have physical, emotional, and psychosocial implications. Despite such risks, many teenage Filipino women still have unintended pregnancies. This study aims to identify factors associated with pregnancy among Filipino women aged 15-19.Methods: We used data from the individual recode of the 2017 Philippine National Demographic and Health Survey. We used logistic regression for survey data to identify determinants associated with teenage pregnancy. Results: Out of 5,120 respondents, 420 (8.56%) have ever been pregnant. After adjusting for confounding variables, we find that there is strong evidence that belonging to the richer (adjusted odds ratio (aOR): 0.51; 95% Confidence Interval (CI): 0.27, 0.97) and richest (aOR: 0.45; 95% CI: 0.22, 0.93) socio-economic strata are protective against teenage pregnancy. Accessing the internet at least once a week (aOR: 0.42; 95% CI: 0.24, 0.74) or almost every day (aOR: 0.45; 95% CI: 0.23, 0.86) are also protective against teenage pregnancy. Among the religions, being Protestant (aOR: 0.46; 95% CI: 0.22, 0.96), or a Muslim (aOR: 0.28; 95% CI: 0.14, 0.58) lower the odds of teenage pregnancy as compared to being Roman Catholic. On the other hand, there is strong evidence that just finishing primary education raises the odds of teenage pregnancy by six times (aOR: 6.25; 95% CI: 1.31, 29.89) as compared to those who did not have any formal education. A year increase in age also increases the odds of teenage pregnancy by 2.93 times (aOR: 2.93; 95% CI: 2.48, 3.46).Conclusions: These findings highlight the need to implement reproductive health education and contraceptive promotion interventions on a nationwide scale. Promoting internet access through investments in internet coverage and speed may also help in further decrease teenage pregnancy. Urgent action is needed considering the prevalence of teenage pregnancy in the country and its rapid increase due to the COVID-19 pandemic.

Abstract
Past three decades to current literature, lanthanum silicates embedded with nickel ions are notable for different opto-electronic and semiconducting use. Current days of opto-electronics, including advanced semiconducting resources, need different assemblies of glass resources employing elastic, luminescent, and electronic characteristics. In this view, the opto-electronic resource of chemical composition Ba(10-x)NixLa30Si60 has planned for synthesis followed by mechanical, thermoluminescent, and opto-electronic characterization. The materials developed are showing glassy behavior, and which was confirmed by the structural characterization. The glass with 0.6 mol% NiO concentration exhibiting better thermal stability. Observations made on the elastic characterization of glasses suggested covalent structure. DTA results which include thermal stabilities of glasses, suggest materials are capable of high thermal stability. Molecular structure of glasses studied with the help of FT-IR spectra. Different structural units and their waves number positions are identified and analysed. Which also suggested glassy behavior. D.C. Conductivity reports suggest that the materials are electrically active, and they are showing few orders of ionic conductivity. A decrease in optical basicity with increasing NiO mol% of glasses suggests high order of covalence. Trap depth parameters (Tm, E𝛕, E𝛅, E𝛚 & ms) under thermoluminescence studies suggest glass with 0.6 mol% NiO concentration is a beneficial TL resource. Optical absorption spectra of glasses is recorded, and which helps to calculate the Racah parameters of glasses. Refractive index, emissive cross-section, optical band gap, and transition probability of nickel hosted present glasses evaluated with the help of photoluminescence characterization. This suggests glasses embedded with nickel ions are highly photonic. All the outcomes from the various characterization of glasses which include mechanical, thermoluminescent, and photo-electronic results, suggest a glass with 0.6 mol% NiO concentration is a helpful thermoelement and opto-electronic resource.
A Type-2 Fuzzy Approach to Driver-Automation Shared Driving Lane Keeping Control of Semi-autonomous Vehicles under Imprecise Premise Variable
Authors: Liu Yue , Xu Qing , Guo Hongyan , ZHANG Hui 
Published: August 2021

Abstract
The driver-automation shared driving is a transition to fully-autonomous driving, in which human driver and vehicular controller cooperatively share the control authority. This paper investigates the shared steering control of semiautonomous vehicles with uncertainty from imprecise parameter. By considering driver’s lane-keeping behaviour on the vehicle system, a driver-automation shared driving model is introduced for control purpose. Based on the interval type-2 (IT2) fuzzy theory, moreover, the driver-automation shared driving model with uncertainty from imprecise parameter is described using an IT2 fuzzy model. After that, the corresponding IT2 fuzzy controller is designed and a direct Lyapunov method is applied to analyze the system stability. In this work, sufficient design conditions in terms of linear matrix inequalities are derived, to guarantee the closed-loop stability of the driver-automation shared control system. Meanwhile, an H ∞ performance is studied to ensure the robustness of the control system. Finally, simulationbased results are provided to demonstrate the performance of the proposed control method. Furthermore, an existing type-1 fuzzy controller is introduced as comparison, to verify the superiority of the proposed IT2 fuzzy controller.
Effects of HIV status and history of pregnancy termination on trends of family planning knowledge among women living in nine fragile countries
Authors: Woytowich Daniel John , Xie Bin 
Published: August 2021

Abstract
Background: To decrease the proportion of women in fragile or conflict-affected situations (FCS) that need, but are not using modern contraception, the global health community must better understand family planning (FP) knowledge gaps; and elucidate which subgroups of women are, and are not, effectively being reached with FP information. This study investigated whether women with notable sexual and reproductive health histories that put them at risk for future pregnancy complications, namely HIV+ women and women with history of terminated pregnancy (HTP), would possess more complete FP knowledge and/or recall being given FP information more readily than HIV- women and women with no HTP (NHTP), respectively. Methods: Knowledge of several contraceptive methods, and the prevalence of women who recalled being given FP information at a healthcare visit, or via TV, radio, or periodical were estimated across HIV, HTP, and country subgroups. HIV+ and HTP status were major predictors in multivariate logistic regressions analyzing the odds of knowing a specified method of contraception or of recalling being given FP information via the modes considered. Results: HIV+ as opposed to HIV- women showed significantly higher odds of knowing about the pill (p=0.001), IUD (p<0.001), injectables (p=0.005), male condoms (p<0.001), female condoms (p<0.001), and implants (p<0.001); but not female or male sterilization. HIV+ women demonstrated higher odds of recalling being given FP information at a health visit (p=0.001), whereas HTP women did not. HTP women showed higher odds (p<0.001) of knowing each modern method of FP with the exception of male sterilization and of recalling TV (p=0.01) and radio (p<0.001) FP messages. Conclusions: Notable findings were the higher FP awareness among HIV+ and HTP women, and the observation that HIV+ women were seemingly provided FP information more readily at healthcare visits than were HTP women, despite their similar risk profiles concerning future pregnancies. Subsequent studies may elucidate why these patterns were observed and indicate which other diagnostic groups are effectively being reached with FP education, and which are not. Understanding trends and predictors of FP knowledge can help practitioners better target FP counseling efforts in FCS toward knowledge gaps and their causes.
AL355338 acts as an oncogenic lncRNA by interacting with protein ENO1 to regulate EGFR/AKT pathway in NSCLC

Published: August 2021

Abstract
Background

Non-small cell lung cancer (NSCLC) is a malignancy with considerable morbidity and mortality. Abnormal metabolism is a hallmark of cancer; however, the mechanism of glycolysis regulation in NSCLC progression is not completely understood. Recent studies suggest that some dysregulated long non-coding RNAs (lncRNAs) play important roles in tumor metabolic reprogramming.
Methods

To identify glycolysis-associated-lncRNAs in NSCLC, we compared RNA-sequencing results between high 18F-fluorodeoxyglucose (FDG)-uptake NSCLC tissues and paired paratumor tissues. The transcript abundance of AL355338 in 80 pairs of clinical samples was evaluated by quantitative real-time PCR assay and fluorescence in situ hybridization. The biological role of AL355338 on NSCLC cells were evaluated by functional experiments in vitro and in vivo. Moreover, RNA pull-down, mass spectrometry and RNA immunoprecipitation (RIP) assays were used to identify the protein interacted with AL355338. Co-immunoprecipitation, in situ proximity ligation assays and western blotting were applied to define the potential downstream pathways of AL355338.
Results

AL355338 was an upregulated glycolysis-associated lncRNA in NSCLC. Functional assays revealed that AL355338 was critical for promoting aerobic glycolysis and NSCLC progression. Mechanistic investigations showed that AL355338 directly bound with alpha-enolase (ENO1) and enhanced the protein’s stability by modulating its degradation and ubiquitination. A positive correlation was observed between AL355338 and ENO1 in NSCLC, and ENO1 was subsequently confirmed to be responsible for the oncogenic role of AL355338. Furthermore, AL355338 was capable of modulating ENO1/EGFR complex interaction and further activating EGFR-AKT signaling.
Conclusions

This study indicates that AL355338 confers an aggressive phenotype to NSCLC, and targeting it might be an effective therapeutic strategy.

Published: August 2021

Abstract
Background

Though relevant education and clinical practice could promote health-seeking behavior, nurses and nursing students may not actively seek healthcare.
Methods

This was a cross-sectional study using an adaptation of the self-reported Health Behavior Questionnaire (HBQ) including sociocultural background, lifestyle, self-assessment of life, health care utilization, and health counseling. 199 valid samples were acquired by convenient sampling. Univariate analysis, Spearman rank correlation, Pearson correlation, and multivariate linear regression were used to analyze the data.
Results

Cultural background, living with family, employment, most items in lifestyle, and all items in perceived life status were correlated with health-seeking behavior. A multivariate linear regression verified the influence of alcohol consumption, financial situation, and work situation on the experience of health care utilization, as well as the influence of physical health and interpersonal relationship on the experience of health counseling.
Conclusions

Less alcohol consumption, better financial situation, and better work situation are positively correlated with health care utilization. Better physical health and sounder interpersonal relationships can improve health counseling. The effect of other factors needs further exploration. Cohort studies could be used to investigate the long-term change in health-seeking behavior.

Published: August 2021

Abstract
Objectives: Musculoskeletal pains are sometimes misdiagnosed in some diseases, like rheumatoid and psoriatic arthritis, erosive OA, etc. Secondary hyperparathyroidism was not considered a differential diagnosis for RA, despite the fact that it can cause arthralgia or arthritis. Also, fibromyalgia is a psychosomatic condition marked by widespread pain and tenderness. Methods: This study included 400 patients attended outpatient clinics of Al-Azhar Faculty of medicine in Egypt, and Elaj Specialized Clinics in Saudi Arabia, who were not fulfilling criteria for RA diagnosis, and not responding to its treatment. Other diseases like psoriatic arthritis and erosive OA were excluded. Criteria for classification of fibromyalgia syndrome were applied to all patients. We did lab tests of RF, ACPA, ESR, CRP, LFT, RFT, vitamin D3, PTH, calcium, phosphorus, and SUA. Radiological imaging modalities for diagnosis or exclusion of suspected diseases were applied. Results: All patients were fulfilling both old and new criteria of fibromyalgia syndrome, and not fulfilling any RA criteria, 18% were seropositive with low RF titers and negative ACPA. All patients had vitamin D3 deficiency or insufficiency. 75% of patients had abnormally high levels of PTH, and had no parathyroid gland pathology. X-rays showed subperiosteal and subchondral resorption of mainly thumbs, subchondral osteopenia of proximal and middle phalanges, mild subperiosteal resorption along the radial aspect of the middle phalanx and mild tuft erosions, besides changes in the carpus closely resembling those of rheumatoid arthritis, of ulnar styloid resorption, radiocarpal and scapho-trapezoid joint arthritis. Of special interest, the presence of tuft spurs-like excrescences.

Published: August 2021

Abstract
Background and Aims: Long non-coding RNAs have been shown to promote or inhibit various cancers, acting as competing endogenous RNAs for specific microRNAs. The primary objective of this research was to investigate the underlying mechanism by which the LINC02027/miR-625-3p/PDLIM5 axis affects proliferation, migration, invasion and apoptosis in hepatocellular carcinoma (HCC). Methods: The level of LINC02027 in HCC tissues and cells and its regulatory effect on the development of HCC were detected. According to the results of database prediction and qRT-PCR, the downstream microRNA and target gene were searched. Finally, HCC cells were transfected with lentivirus and used for cell function assays (in vitro) and subcutaneous tumorigenesis assay in nude mice (in vivo).Results: Downregulation of LINC02027 was detected in HCC tissues and cell lines. The knockdown or overexpression of LINC02027 increased or reduced the proliferation migration and invasion of HCC cells, and the apoptotic ability of HCC cells decreased or increased, respectively. Mechanistically, INC02027 inhibited epithelial-to-mesenchymal transition (EMT). As a ceRNA, LINC02027 inhibited the malignant ability of HCC by competitively binding to miR-625-3p to regulate the expression of PDLIM5 and the activity of RAS-MAPK pathway.Conclusion: LINC02027/miR-625-3p/PDLIM5 axis inhibits the EMT and promotes apoptosis of HCC by regulating RAS-MAPK pathway.
On the Role of Atmospheric Simulations Horizontal Grid Spacing for Flood Modeling
Authors: Quintero Felipe , Villarini Gabriele , Prein Andreas F. , Krajewski Witold F. , Zhang Wei 
Published: August 2021

Abstract
Our study focuses on the hydrologic implications of resolving and modeling atmospheric processes at different spatial scales. Here we use heavy precipitation events from an atmospheric model that was run at different horizontal grid spacings (i.e., 250 m, 500 m, 1 km, 2 km 4 km, and 12 km) and able to resolve different processes. Within an idealized simulation framework, these rainfall events are used as input to an operational distributed hydrologic model to evaluate the sensitivity of the hydrologic response to different forcing grid spacings. We consider the finest scale (i.e., 250 m) as reference, and compute event peak flows and volumes across a wide range of basin sizes. We find that the use of increasingly-coarser inputs leads to changes in the distribution of event peak flows and volumes, with the strongest sensitivity at the smallest catchment sizes. Overall, we find that 4-km rainfall simulations represent a good compromise between computational costs and hydrologic performance, providing basic information for future endeavors geared towards regional downscaling.
