Published: May 2021

Abstract
The coordinated development of land and water resources and the ecological environment is essential to regional sustainable development. In view of the current rapid development of information science, the coordination degree of eco-environmental systems has been evaluated from the perspective of development rate. Taking the major grain-producing areas in China as an example, this study used information entropy to determine the weights of various indicators and introduced the average annual growth rate to characterize the development rates of indicators. Through an improved dynamic coupling and coordination model, the coupling and coordination indices of the system and subsystems of land and water resources with the ecological environment were obtained. These indices were analyzed and compared with those generated from raw data. The results showed that during the study period, the land and water resources and the ecological-environmental system had a relatively low coupling, with reluctant coordination, and had a relatively low level of coordinated development. Compared with the results based on raw data, the development rate method yielded similar results on the coupling of subsystems. For the analysis of trends, the method using development rate characteristics better reflected the overall coupling of the system, as well as the coordination of the system when considering the range of relative changes. Therefore, evaluation results based on development rate characteristics can, to a certain degree, better help decision-makers timely understand the coordinated development of the land and water resources and the ecological-environmental system.

Abstract
In recent decades, the amount of water in Urmia Lake has faced a considerable decrease. Several studies evaluated agricultural development as one of the main governing factors. The current study investigates the effect of agricultural development on the amount of streamflow in one of the main Urmia Lake sub-basins. To focus on agricultural development, a novel method using DEM and NDVI information was utilized to distinguish the agriculture class for selected years. Outputs of SWAT model for different years and scenarios revealed that agricultural development from the year 1977 to 2015, increased the annual evapotranspiration from 295 to 308 mm, and decreased the annual streamflow from 317 mcm to 300 mcm for the irrigation scenario. In addition, the groundwater level fluctuations captured by the SWAT, showed 1.9 meters drawdown in the Sarab plain from the year 1992 to 2003, which was in accordance with the observed trend during this period.
Supine Versus Upright Exercise in Patients With Hepatopulmonary Syndrome and Orthodeoxia: Study Protocol for a Randomized Controlled Crossover Trial

Published: May 2021

Abstract
Background: The hepatopulmonary syndrome (HPS) is a pulmonary complication of liver disease found in 10 to 32% of patients with cirrhosis and characterized by intrapulmonary vascular dilatations and abnormal oxygenation. Liver transplantation is the only effective therapy for this disease. Patients with HPS have significant exercise limitation, impacting their quality of life and associated with poor liver transplant outcomes. Many patients with HPS exhibit orthodeoxia – an improvement in oxygenation in the supine compared to the upright position. We hypothesize that exercise capacity will be superior in the supine compared to the upright position in such patients.Methods: We propose a randomized controlled cross-over trial in patients with HPS and orthodeoxia, comparing the effect of supine versus upright position on exercise. Participants will be randomized to cycle ergometry in either the supine or upright position, followed by a crossover to the alternate position after a minimum of 1 day to a maximum of 4 weeks. Exercise will be performed at a constant work rate of 70-85% of the predicted peak work rate until the “stopping time” is reached, defined by exhaustion, profound desaturation, or safety concerns (drop in systolic blood pressure or life-threatening arrhythmia). The primary outcome will be the difference in stopping time between exercise positions.Discussion: HPS patients have hypoxemia leading to significant exercise limitation. If our study is positive, a supine exercise regimen could become a routine prescription for patients with HPS and orthodeoxia, enabling them to exercise more effectively. Future studies could explore the corresponding effects of a supine exercise training regimen on physiologic variables such as long-term exercise capacity, quality of life, dyspnea, and liver transplantation outcomes.

Design and Simulation of a Very Fast and Compact All-Optical Full-Subtractor Based an Nonlinear Effect in 2D Photonic Crystals
Authors: Beiranvand Reza , Mir Ali , Talebzadeh Reza 
Published: May 2021

Abstract
In this paper, by using the non-linear effects and also destructive and constructive interferences between waveguides, we have designed and simulated an all-optical full-Subtractor based on two-dimensional photonic crystals. The proposed Subtractor has a very simple structure which is composed of 33×31 silicon rods immersed in air in a square lattice and involves three input ports (bits) and an additional waveguide to exhaust the unwanted light. We imposed some defect rods to control the behavior of the light. The used non-linear material, is a doped glass with 1.4×10− 14 m2/w non-linear refractive index which is very greater than the non-linearity refractive index of silicon, 3.46×10− 20 m2/w. Since the proposed structure is very simple and compact, it can be applicable in optical integrated circuits and optical calculations.

Published: May 2021

Abstract
Accurately and objectively simulating the dynamic evolution of the behaviors of different decision-makers (DMs) is essential for identifying solutions to transboundary water conflicts. This research proposes an improved Graph Model for Conflict Resolution (GMCR) based on the benefits of DMs’ behaviors to model the dynamic evolution of transboundary water conflicts. Additionally, the influence of third-party intervention on conflicts is investigated in depth. A demonstration area in the Yangtze River Delta on ecologically friendly development (DAYRD) in China is taken as the case study area. The results indicate that the improved GMCR model based on the benefit function can not only clearly identify the dynamic evolution path of transboundary water conflicts into cooperation, but also effectively avoid the influence of the subjective factors of researchers or experts in traditional methods. In addition, a third party with higher powers is the key to resolving transboundary water conflicts in the DAYRD. The implementation of punishment measures by a third party can change the status quo of water conflicts and boost effective cooperation among governments. The punishment amount should be greater than the protection costs shared by local governments. These findings provide experience for the resolution of transboundary water conflicts and enhance our understanding of the role of third parties in transforming conflict into cooperation.

Published: May 2021

Abstract
Sulfinyl radicals – one of the fundamental classes of S-centered radicals – have eluded synthetic application in organic chemistry for over 60 years, despite their potential to assemble valuable sulfoxide compounds. Here we report the successful generation and use of sulfinyl radicals in a dual radical addition / radical coupling with unsaturated hydrocarbons, where readily-accessed sulfinyl sulfones serve as the sulfinyl radical precursor. The strategy provides an entry to a variety of previously inaccessible linear and cyclic disulfurized adducts in a single step, and demonstrates excellent tolerance to an extensive range of hydrocarbons and functional groups. Experimental and theoretical mechanistic investigations suggest that these reactions proceed through sequential sulfonyl and sulfinyl radical addition.

Published: May 2021

Abstract
Improving the surface roughness and reducing the surface energy are the main strategies for constructing cotton fabrics with superhydrophobic surface. However, the complex finishing process and poor durability still impede the production and application of superhydrophobic cotton fabrics. Therefore, it is critical to produce superhydrophobic fabrics with excellent durability via a noncomplicated method. In this work, monomers of methyl methacrylate (MMA) and trifluoroethyl methacrylate (TFMA) were polymerized via free radical polymerization to produce a fluoropolymer. Then, the fabric was coated with the fluoropolymer to construct a superhydrophobic surface via the pad-dry-cure technology. The TFMA unit in the fluoropolymer had lower surface energy than the MMA unit. Under the high-temperature curing condition, the MMA unit in the fluoropolymer was grafted onto the cotton fabric via transesterification, and the TFMA was exposed on the fabric surface. The finished fabric showed durable superhydrophobic properties, outstanding oil–water separation properties, and excellent self-cleaning properties. Given the results, the finished fabric has great potential application in clothing and industrial fields.

Abstract
The effective utilisation of thermal energy is crucial to a world aiming at sustainable development goals. The sensitised thermal cell (STC) is a new thermal energy conversion technology, which was reported in 2017, for generating electricity via the redox reactions of electrolyte ions with thermally excited carriers in semiconductors. STC is attracting attention as a technology that could affect oil prices globally. Here, we report the successful construction of STC, which discharges and recovers well at room temperature, by studying the interelectrode and ion diffusion distances. The fabricated STC is thinner than 0.5 mm and can be rendered flexible. Further, STCs, which possess a power generation capacity of 0.1 microA, 100 mV per 1 mm2 area, and shall be installed “in” internet-of-things (IoT) devices, drainage pipes, and walls in the future.

Abstract
Background: Transplant Renal Artery Stenosis (TRAS) is the main vascular complication of kidney transplantation. For research and treatment purposes, several authors consider critical renal artery stenosis to be greater than 50%, and percutaneous intervention is indicated in this scenario. However, there are no reports in the current literature on the evolution of patients with less than 50% stenosis.Method: Retrospective study includes data from all patients that were submitted to kidney transplantation and were suspected TRAS after transplantation with stenosis under 50% independent on age, who were referred for angiography at a single center between January 2007 and December 2014. Results: During this period, 6,829 kidney transplants were performed at Hospital do Rim, 313 of them had clinical suspicion of TRAS and 54 were those who presented no-significant stenosis. The average age was 35.93 years old, the predominant gender was male and most individuals (94.4%) were submitted to dialysis before transplantation. Transplants, in most cases in this group, occurred from a deceased donor, 66.7%. The time between transplantation and angiography was less than one year in 79.6% of patients and all presented no-significant TRAS. Creatinine levels, Systolic Blood Pressure, Diastolic Blood Pressure and the glomerular filtration rate improved over the long term. The outcomes found were death and renal loss.Conclusion: Age, sex and ethnic group of patients are factors that did not interfere with the frequency of renal artery stenosis. The outcomes showed that in the long term most patients evolve well, and have improved quality of life and kidney function, although there are cases of death and kidney loss.

Published: May 2021

Abstract
This research presents the development of novel self-cleaning cotton fabric with dual functionalities of superhydrophobicity and photocatalytic activity. Fluorine-free coating formulations composed of either flower-like TiO2 or nitrogen-doped TiO2 particles, with a hierarchical surface morphology, and polydimethyl siloxane (PDMS) polymer were applied to cotton fabrics using a facile dip-coating method. The self-cleaning performance of fabrics was assessed based on their superhydrophobicity and effective removal of oil-based food stains. Additionally, the impact of nitrogen doping on photocatalytic activity of flower-like TiO2 particles was investigated. The obtained results demonstrated that the presence of both PDMS and hierarchical particles generated excellent superhydrophobicity on the cotton fabric with a water contact angle of 156.7 ± 1.9⁰. In addition, the coated fabric exhibited highly efficient photocatalytic activity, decomposing stains under simulated sunlight. Nitrogen doping process significantly boosted the photocatalytic activity of TiO2 particles in degrading stains and dye solution. The developed superhydrophobic fabric showed high robustness against both chemical and physical durability tests. This research contributes significantly to the continued advancement of highly efficient self-cleaning textiles via the development of dual functions of superhydrophobicity and photocatalytic activity.
Cervical cerclage or not in delayed delivery interval: obstetric management and outcomes
Authors: Yu Nan , Gong Xun 
Published: May 2021

Abstract
Objective

The aim of this study is to explore the effectiveness of cervical cerclage in order to delay the delivery interval after delivery of the first fetus in dichorionic twin pregnancies.
Study Design:

Records of 11 twin pregnancies where delayed delivery was experienced for retained fetus(es), were collected retrospectively. Cases with cervical cerclage placed after the first delivery were evaluated as the cerclage group and cases without cerclage placement were evaluated as the non-cerclage group.
Results

The median duration of the delay 25.4 ± 8.1days (range, 4–50) in the cerclage group and 7.7 ± 2.0 days(range, 3–17) in the non-cerclage group (P = 0.045). Average gain birthweight of the second fetus in the cerclage group was 408.0 ± 160.2 g and 93.3 ± 25.5g in the non-cerclagegroup(P = 0.061). But other parameters were not different between the two groups.
Conclusions

Cervical cerclage after the first delivery is associated with a longer inter-delivery interval without increasing the risk of intrauterine infection.
RISM-Assisted Analysis of the Role of Alkali Metal Hydroxides in the Solvation of Cellulose in Alkali/urea Aqueous Solutions
Authors: Huh Eugene , Yang Ji-Hyun , Lee Chang-Ha , Ahn Ik-sung , Mhin Byung Jin 
Published: May 2021

Abstract
The three-dimensional reference interaction site model theory with the Kovalenko-Hirata closure (3D-RISM-KH) combined with the Kirkwood-Buff integral (KBI) was used to clarify the role of alkali metal hydroxides (MOHs) in cellulose solvation in alkali/urea aqueous solutions. The KBI and excess number of MOHs showed that their access and affinity to cellulose were both in the order LiOH > NaOH > KOH. The cavity and interaction volumes for cellulose indicate that the alkali metal ions closer in proximity to cellulose induce thermal fluctuations of cellulose molecules more easily and cause more electrostatic interactions and hydrogen bonding with cellulose. These calculation results support the hypothesis of cellulose charging up, which claims that cellulose-ion interactions cause cellulose solvation. The energy and chemical potential of cellulose solvation confirmed the affinity and interaction of MOHs with cellulose. Solvent reorganization, whose energy primarily determined the solvation energy, was found to be facilitated by the more proximal MOH when in the presence of urea. 3D-RISM-KH combined with KBI produced quantitative information regarding the distribution and attractive interaction of MOHs (especially LiOH) with cellulose, which clarified their role in cellulose solvation in alkali/urea aqueous solutions.

Abstract
Some studies have shown that maternal exposure to perfluoroalkyl substances (PFASs) may be associated with early attention deficit hyperactivity disorder (ADHD) in children. The purpose of this systematic review and meta-analysis is to verify this association by reviewing existing studies and to provide a strong basis for preventing ADHD. The researchers searched electronic databases such as PubMed, Science Direct, Scopus, Google Scholar, Web of Science, and Embase for all studies published before October 2020. Finally, we included nine articles for analysis. Our meta-analysis showed that maternal exposure to PFASs was not significantly associated with the prevalence rate of early childhood ADHD (perfluorooctanoic acid (PFOA): odds ratio (OR) = 1.00, 95% confidence interval (95% CI) = 0.75–1.25; perfluorooctane sulfonate (PFOS): OR = 1.01, 95% CI = 0.88–1.14; perfluorohexane sulfonate (PFHxS): OR = 1.08, 95% CI = 0.80–1.09; perfluorononanoic acid (PFNA): OR = 1.13, 95% CI = 0.99–1.28; perfluorodecanoic acid (PFDA): OR = 1.23, 95% CI = 0.15–2.32). Due to significant heterogeneity, we subsequently performed subgroup analysis and sensitivity analysis. In conclusion, a causal relationship between maternal PFASs exposure and ADHD in children was unlikely. Among them, PFOS, PFNA and ADHD might have positive associations worthy of further investigation.

Published: May 2021

Abstract
Atrial fibrillation (AF) is an arrhythmia that can cause blood clot and may lead to stroke and heart failure. To detect AF, deep learning-based detection algorithms have recently been developed. However, deep learning models were often trained with limited datasets and were evaluated within the same datasets, which makes their performance generally drops on the external datasets, known as data dependency. For this study, three different databases from PhysioNet were used to investigate the data dependency of deep learning-based AF detection algorithm using the residual neural network (Resnet). Resnet 18, 34, 50 and 152 model were trained with raw electrocardiogram (ECG) signal extracted from independent database. The highest accuracy was about 98–99% which is evaluation results of test dataset from the own database. On the other hand, the lowest accuracy was about 53–92% which was evaluation results of the external dataset extracted from different source. There are data dependency according to the train dataset and the test dataset. However, the data dependency decreased as a large amount of train data.
Mothers With Depressed Mood: Help-seeking From Husbands and Child-rearing Behaviors
Authors: Katayama Miho , Kitaoka Kazuyo , Aijo Ritsuko 
Published: May 2021

Abstract
Background: Mothers with depressed mood tend not to seek help or support from others. Yet, there is no research providing a detailed examination of the processes that mothers with depressed mood undergo while seeking child-rearing support from their husbands. This study aimed to clarify the processes that mothers with depressed mood go through in seeking child-rearing support from their husbands and performing child-rearing duties. Methods: The participants were 10 mothers living in Japan who had given birth within the past three years and were suspected of having depression after screening using the Edinburgh Postnatal Depression Scale. Semi-structured interview data were analyzed based on the grounded theory.Results: The responses revealed that the mothers felt as though they had insufficient time for themselves, which impelled them to seek support from their husbands, consequently leading them to conclude either that child-rearing and housework are difficult or that child-rearing can be managed some way or another. Conclusion: When the husbands fully cooperated in child-rearing or demonstrated their willingness to cooperate in child-rearing, despite difficulty, the wives accepted their child-rearing support. On the other hand, if the husbands did not recognize their wives’ efforts, the wives did not accept their support, even if they had helped with child-rearing. In this way, the wives re-evaluated their relationship with the husbands based on their husbands’ attitudes toward child-rearing.
