Ultralong-range polyatomic Rydberg molecules formed by a polar perturber

The internal electric field of a Rydberg atom electron can bind a polar molecule to form a giant ultralong-range stable polyatomic molecule. Such molecules not only share their properties with Rydberg atoms (such as long lifetimes and large sizes) but they also possess huge permanent electric dipole moments and in addition allow for coherent control of the polar molecule orientation. In this work, we include additional Rydberg manifolds which couple to the nearly degenerate set of Rydberg states employed in the previous work (S T Rittenhouse and H R Sadeghpour 2010 Phys. Rev. Lett. 104 243002). The coupling of a set of (n + 3)s Rydberg states with the n(l > 2) nearly degenerate Rydberg manifolds in alkali metal atoms leads to pronounced avoided crossings in the Born–Oppenheimer potentials. Ultimately, these avoided crossings enable the formation of the giant polyatomic Rydberg molecules with standard two-photon laser photoassociation techniques.
Study of the Effect of an Environmentally Friendly Flood Risk Reduction Approach on the Oman Coastlines during the Gonu Tropical Cyclone (Case Study: The Coastline of Sur)

Tropical cyclones may be destructive in the coastal region, such as the Gonu tropical cyclone, which affected the Arabian Peninsula and parts of southern Iran in 2007. In this study, a coupled MIKE 21/3 HD/SW (hydrodynamic/spectral wave) model was used to simulate the inland flooding inside the Sur port during the Gonu tropical cyclone. The MIKE 21 Cyclone Wind Generation (CWG) tool was utilized to generate the cyclone’s wind and pressure field. The required input data were obtained from the International Best Track Archive for Climate Stewardship (IBTrACS) and imported into the CWG tool. In this study, the wind and pressure fields were compared between the analytical vortex model and European Centre for Medium-Range Weather Forecasts (ECMWF) data during the Gonu cyclone passage. Moreover, by developing a new model, artificial Mangroves’ effect on inland flooding was investigated. The results show that, contrary to the ECMWF data, the analytical vortex models well captured the storm event’s wind and pressure field. Furthermore, the flood hazard is calculated based on the inundation depth, flow velocity, and area’s vulnerability. The flood hazard map shows that 5% of the coast is at high-risk, 49% is at medium-risk, and 46% is at low-risk class in the Sur port. By applying Mangroves as flood risk reduction, the high-risk area is almost completely removed. However, medium and low-risk zones increase by 50% and 50%, respectively. This information could be helpful in disaster risk reduction and coastal management in the future.
Smartphone hedonic price study based on online retail price in Indonesia

The price of a smartphone is determined by its series of specifications, which makes it suitable to be modelled with a hedonic approach. We collected smartphone prices from various e-commerce along with the specifications using web scraping method. This study demonstrates statistical analysis of smartphone prices in Indonesia by constructing a hedonic model and investigate key variables determining smartphone price. An OLS regression model is employed to total of 1120 handsets data to construct a hedonic model. In addition, random forest regression and XGBoost regression were used to determine the variable importance. The results indicated that only 2 of 5 brands are significantly influence the price of smartphones; Xiaomi and Realme. Meanwhile, the other variables such as RAM, Internal Storage, NFC, Screen Size and Weight have significant positive effect on smartphone prices. In contrast to the use of brand as a weighing basis for calculating CPI, we discovered that RAM is the ultimate key variable determining smartphone prices.
Factors Affecting Continued Use of Online Health Information Seeking Behaviour Among Parents in Developing Countries

The advancement of technology has changed how parents engage in health information seeking activities through the Internet. Such trends not only shown in developed countries but also most of developing economies as the growth of population access to Internet have been steadily increased in the past ten years. Despite the growing penetration rate, little is known on the extent the Internet is being used by parents to obtain health-related information to improve the wellbeing of their children in developing countries. Five hundred and nineteen responses were collected from parents in selected areas of Klang Valley region in Malaysia. The collected data were analysed by partial least square method of structural equation modelling. The results indicated a positive relationship between information satisfaction and online health information seeking continued use. The moderating role of household income and education are confirmed. The research implications of our results would help medical practitioners and policymaker to design the appropriate supports and awareness programs for parents on the risk and benefits of using online health information.
Effect of controlling maximum-SNR-based relay selection strategy in cooperative wireless communication systems

Relay selection strategy under maximum-signal-to-noise ratio (MAX-SNR) criterion was proven to maximize performance but at the expense of losing fairness among the cooperative relays. In this work, the effect of controlling the MAX-SNR criterion on the spectral efficiency of cooperative wireless communication system with adaptive modulation is investigated. Specifically, the probability density function (PDF) of the end-to-end SNR for the considered system is derived when the controlled selection criterion is considered. Base on that PDF, the average spectral efficiency is then derived and investigated. The results show how the spectral efficiency of the system deteriorates as controlling the selection of a relay. Furthermore, the results of Monte Carlo simulation validate the derived expression.
Copper species supported in polysaccharide-based materials: from preparation to application in catalysis

ABSTRACT Cu species (ions or nanoparticles) have gained considerable attention in many research fields, mainly in catalysis. In particular, the development of novel support materials, especially those based on polysaccharides, has allowed using Cu-based catalysts in a vast number of applications. Polysaccharides show attractive characteristics that encourage the researchers to develop support materials with varied sizes and geometry capable of immobilizing various Cu species. Herein, we comprehensively discuss the main advances related to the development of catalysts based on Cu-supported in polysaccharide-based materials along with their application in heterogeneous catalysis. Finally, some perspectives on the future directions toward the development and application of these catalysts are provided.
RPLIE: RPL for indoor environments under midterm link fluctuations

Link dynamics due to environmental change is a critical challenge for wireless networking, and handling it is essential for wireless protocols, especially for low-power and lossy multihop wireless networks (LLNs). Prior work have only studied methods to detect and cope with short-term and long-term link dynamics in LLN. In this work, we tackle the midterm dynamics due to the opening and closing of doors and windows that can happen in a time scale of a few minutes to hours in an indoor LLN. Specifically, we study how midterm link fluctuations impact the performance of standard IPv6 routing protocol for LLN (RPL), and design ‘RPLIE,’ a novel and backward-compatible lightweight enhancement to RPL that detects and overcomes the negative impact of such dynamics. We define ‘opportunistic links’ and propose a novel routing metric, expected breakage cost (EBC), which represents the expected number of link transmissions required from a link breakage to a routing parent change. We implement RPLIE on real embedded devices, and evaluate its performance against the standard RPL via experiments on a 31-node testbed to show that RPLIE achieves significantly better packet delivery performance while using less overhead.
There Is No Fool Like an Old Fool: The Experiences of Elderlies Regarding Remarriage in Iran

Objectives: Despite the positive effects of remarriage on elderlies’ quality of life, marriage in this period is a taboo among people of the society. Therefore, this study aimed to explore the experiences of the elderly regarding remarriage. Methods: This conventional content analysis study was conducted in Iran during 2018. Semi-structured interviews with 20 elderlies living in Tehran were conducted to collect data. For data analysis, Graneheim and Lundman’s approach was adopted. The interviews were continued until reaching data saturation. Results: After data analysis, four main categories and 14 subcategories appeared. The main categories included “there is no fool like an old fool”, “spring in autumn”, “gift of old age”, and “realistic choice. ” Conclusions: Remarriage prevents many future problems for elderlies, such as the feeling of rejection, loneliness, isolation, depression, and low self-esteem. Therefore, serious efforts and planning are required to promote the knowledge level of the society regarding this issue.
Segregation of large particles in dense granular flows suggests a granular Saffman effect

We report on the scaling between the lift force and the velocity lag experienced by a single particle of different size in a monodisperse dense granular chute flow. The similarity of this scaling to the Saffman lift force in (micro-) fluids, suggests an inertial origin for the lift force responsible for segregation of (isolated, large) intruders in dense granular flows. We also observe an anisotropic pressure field surrounding the particle, which potentially lies at the origin of the velocity lag. These findings are relevant for modeling and theoretical predictions of particle-size segregation. At the same time, the suggested interplay between polydispersity and inertial effects in dense granular flows with stress and strain gradients, implies striking new parallels between fluids, suspensions, and granular flows with wide application perspectives.
Mediating Role of Job Satisfaction between Work-To-Family Conflict and Safety Participation among Commercial Drivers of Pakistan

Employee’s safety has come under limelight of organizational policy. Organizations are investing on employee safety training and participation to build their image as well as to contribute in employee well-being. Previous literature suggested association between strains based work-to-family conflicts, job satisfaction, and safety participation. The purpose of this empirical paper is to investigate the effect of work family conflict on safety participation with mediating role of job satisfaction. Moreover, the social exchange theory was adopted to explain research framework of the study. The research was quantitative in nature and adopted cross-sectional research design. Data was collected from 217 respondents by using convenience sampling technique in Karachi region. The research finding reveal new insight by providing evidence of insignificant direct association between strains based work family conflict andsafety participation. Furthermore, finding also reveals that job satisfaction significantly mediates the relationship of strains based work family conflict with safety participation.This paper was originally inspired by world Health organization (WHO)news, which reported thatone million individual died every yeardue to street accidents in the world.
Repurposing Multi-Targeting Plant Natural Product Scaffolds In Silico Against SARS-CoV-2 Non-Structural Proteins Implicated in Viral Pathogenesis

Background: Accessing COVID-19 vaccines is a challenge despite successful clinical trials. This burdens the COVID-19 treatment gap, thereby requiring accelerated discovery of anti-SARS-CoV-2 agents. Thus, this study explored the potential of anti-HIV reverse transcriptase (RT) phytochemicals as inhibitors of SARS-CoV-2 non-structural proteins (nsps) by targeting in silico key sites in the structures of SARS-CoV-2 nsps. Moreover, structures of the anti-HIV compounds were considered for druggability and toxicity. 104 anti-HIV phytochemicals were subjected to molecular docking with papain-like protease (nsp3), 3-chymotrypsin-like protease (nsp5), RNA-dependent RNA polymerase (nsp12), helicase (nsp13), SAM-dependent 2’-O-methyltransferase (nsp16) and its cofactor (nsp10), and endoribonuclease (nsp15). Drug-likeness and ADME (absorption, distribution, metabolism, and excretion) properties of the top ten compounds per nsp were predicted using SwissADME. Their toxicity was also determined using OSIRIS Property Explorer. Results: Among the twenty-seven top-scoring compounds, the polyphenolic natural products amentoflavone (1), robustaflavone (4), punicalin (9), volkensiflavone (11), rhusflavanone (13), morelloflavone (14), hinokiflavone (15), and michellamine B (19) were multi-targeting and had the strongest affinities to at least two of the nsps (Binding Energy = -7.7 to -10.8 kcal/mol). Friedelin (2), pomolic acid (5), ursolic acid (10), garcisaterpenes A (12), hinokiflavone (15), and digitoxigenin-3-O-glucoside (17) were computationally druggable. Moreover, compounds 5 and 17 showed good gastrointestinal absorptive property. Most of the compounds were also predicted to be non-toxic. Conclusions: Twenty anti-HIV RT phytochemicals showed multi-targeting inhibitory potential against SARS-CoV-2 nsp3, 5, 10, 12, 13, 15, and 16, and can therefore be used as prototypes for anti-COVID-19 drug design.
Uncertainties in Atmospheric River Lifecycles by Detection Algorithms: Climatology and Variability

Atmospheric rivers (ARs) are long and narrow filaments of vapor transport that are responsible for most poleward moisture transport outside of the tropics. Many AR detection algorithms have been developed to automatically identify ARs in climate data. The diversity of these algorithms has introduced appreciable uncertainties in quantitative measures of AR properties and thereby impedes the construction of a unified and internally consistent climatology of ARs. This paper compares nine global AR detection algorithms from the perspective of AR lifecycles following the propagation of ARs from origin to termination in the MERRA2 reanalysis over the period 1980–2017. Uncertainties in AR lifecycle characteristics, including event number, lifetime, intensity, and frequency distribution are discussed. Notably, the number of AR events per year in the Northern Hemisphere can vary by a factor of 5 with different algorithms. Although all algorithms show that the maximum AR origin (termination) frequency is located over the western (eastern) portion of ocean basins, significant disagreements appear in regional distribution. Spreads are large in AR lifetime and intensity. The number of landfalling AR events produced by the algorithms can vary from 16 to 80 events per year, although the agreement improves for stronger ARs. By examining the ARs' connections with the Madden‐Julian Oscillation and El Niño Southern Oscillation, we find that the overall responses of ARs (such as changes in AR frequency, origin, and landfall activity) to climate variability are consistent among algorithms.
Effect of Pre-Harvest Supplemental UV-A/Blue and Red/Blue LED Lighting on Lettuce Growth and Nutritional Quality

Blue light and ultra-violet (UV) light have been shown to influence plant growth, morphology, and quality. In this study, we investigated the effects of pre-harvest supplemental lighting using UV-A and blue (UV-A/Blue) light and red and blue (RB) light on growth and nutritional quality of lettuce grown hydroponically in two greenhouse experiments. The RB spectrum was applied pre-harvest for two days or nights, while the UV-A/Blue spectrum was applied pre-harvest for two or four days or nights. All pre-harvest supplemental lighting treatments had a same duration of 12 h with a photon flux density (PFD) of 171 μmol m−2 s−1. Results of both experiments showed that pre-harvest supplemental lighting using UV A/Blue or RB light can increase the growth and nutritional quality of lettuce grown hydroponically. The enhancement of lettuce growth and nutritional quality by the pre-harvest supplemental lighting was more effective under low daily light integral (DLI) compared to a high DLI and tended to be more effective when applied during the night, regardless of spectrum.
Influence of Community Factors on Water Saving in a Mega City after Implementing the Progressive Price Schemes

A progressive price scheme (PPS) has been implemented in Shanghai since 2013 in consideration of residents’ ability to pay, and charges are based on the actual water consumption of the residents, in an effort to balance the rational allocation of water resources and the goal of saving water between rich and poor families. In the current work, the effect of the PPS for water use was evaluated based on the water use of 6661 households from 14 communities in Shanghai. It was found that the PPS did not reduce household water consumption when comparing the water consumption per household both before and after the implementation of the PPS policy. To investigate the weakness of the PPS, a principal component analysis (PCA) and a hierarchical cluster analysis (HCA) were conducted to access the relationships between mean household water use and community factors such as housing price, management fees, and the number of parking sites. Moreover, a significant inverted U-shaped curve between housing price and water use was found, which demonstrates that rental households shared by several tenants were the main consumers of residential water, and they were not sensitive to the water price improvement in the PPS due to sharing water prices. Therefore, a proposal was made in this work to increase the proportion of water fee expenditure in the total household income and to use 3% as the benchmark for water affordability. Our results provided a new picture of residential water use in big cities and a method for saving and balancing urban water resources.
The impact of land use on future water balance - A simple approach for analysing climate change effects

Abstract: Regional climate change projections for Europe agree in predicting a statistically significant warming in all seasons. The most significant climate change effect is its impact on water cycle through altering precipitation patterns and evapotranspiration processes at multiple scales. The anticipated changes in the distribution and precipitation amounts together with continuously increasing temperatures may induce a higher rate of water consumption in plants, which can generate changes in soil moisture, groundwater, and the water cycle. Thus, climate change can cause changes in the water balance equations structure. A Thornthwaite-type monthly step water balance model was established to compare the water balance in three different surface land cover types: (i) a natural forested area; (ii) a parcel with mixed surface cover; (iii) an agricultural area. The key parameter of the model is the water storage capacity of the soil. Maximal rooting depth of the given area is also determinable during the calibration process using actual evapotranspiration (AET) and soil physical data. The locally calibrated model was employed for assessing future AET and soil moisture of selected land cover types using data from four bias-corrected regional climate models. The projections demonstrate increasing actual evapotranspiration values in each surface cover type at the end of the 21st century. Regarding the 10th percentile minimum soil moisture values, the forested area displayed an increasing trend, while the agricultural field and mixed parcel showed a strong decrease. The 30-year monthly means of evapotranspiration shows the maximum values in June and July, while the minimum soil moisture in September. Water stress analysis indicates water stress is expected to occur only in the agricultural field during the 21st century. The comparison of the three surface covers reveals that forest has the greatest soil water storage capacity due to the highest rooting depth. Thus, according to the projections for 21st century, less water stress is predicted to occur at the forested area compared to the other two surface covers which shows shallow rooting depth.
What Is the Macroeconomic Impact of Higher Decarbonization Speeds? The Case of Greece

In alignment with the European Union’s legislation, Greece submitted its final 10-year National Energy and Climate Plan (NECP) in December 2019, setting more ambitious energy and climate targets than those originally proposed in the draft version of the document. Apart from higher penetration of renewable energy sources (RES), the final NECP projects also zero carbon use in power generation till 2030. Although decarbonization has long been regarded beneficial for economies that base their energy production on coal, as it is the case with Greece, the macroeconomic and societal ramifications of faster transitions to carbon-free economies remain highly unexplored. Under this context, in this paper, we soft-link energy models, namely Times-Greece and Primes, with a macroeconomic model, namely Global Trade Analysis Project (GTAP), to measure the effects of the final and draft NECPs on the Greek economy and evaluate the impact of higher decarbonization speeds. We find that the faster transition scenario displays both economic and societal merits, increasing Gross Domestic Product (GDP) and household income by about 1% and 7%, respectively.
RUFY3 links Arl8b and JIP4-Dynein complex to regulate lysosome size and positioning

The bidirectional movement of lysosomes on microtubule tracks regulates their whole-cell spatial arrangement. Arl8b, a small GTP-binding (G) protein, promotes lysosome anterograde trafficking mediated by kinesin-1. Herein, we report an Arl8b effector, RUFY3, which regulates the retrograde transport of lysosomes. We show that RUFY3 interacts with the JIP4-dynein-dynactin complex and facilitates Arl8b association with the retrograde motor complex. Accordingly, RUFY3 knockdown disrupts the positioning of Arl8b-positive endosomes and reduces Arl8b colocalization with Rab7-marked late endosomal compartments. Moreover, we find that RUFY3 regulates nutrient-dependent lysosome distribution, although autophagosome-lysosome fusion and autophagic cargo degradation are not impaired upon RUFY3 depletion. Interestingly, lysosome size is significantly reduced in RUFY3 depleted cells, which could be rescued by inhibition of the lysosome reformation regulatory factor PIKFYVE. These findings suggest a model in which the perinuclear cloud arrangement of lysosomes regulates both the positioning and size of these proteolytic compartments. Lysosomes move along microtubule tracks, and Arl8b is known to stimulate their anterograde transport. Here, the authors identified RUFY3 as an Arl8b effector that interacts with dynein-dynactin to drive retrograde transport and perinuclear lysosome positioning.
