SEEUNRS: Semantically Enriched Entity-Based Urdu News Recommendation System

The advancement in the production, distribution, and consumption of news has fostered easy access to the news with fair challenges. The main challenge is to present the right news to the right audience. The news recommendation system is one of the technological solutions to this problem. Much work has been done on news recommendation systems for the major languages of the world, but trivial work has been done for resource-poor languages like Urdu. Another significant hurdle in the development of an efficient news recommendation system is the scarcity of an accessible and suitable Urdu dataset. To this end, an Urdu news mobile application was used to collect the news data and user feedback for 1 month. After refinement, the first-ever Urdu dataset of 100 users and 23,250 news was curated for the Urdu news recommendation system. In addition, SEEUNRS , a semantically enriched entity-based Urdu news recommendation system, is proposed. The proposed scheme exploits the hidden features of a news article and entities to suggest the right article to the right audience. Results have shown that the presented model has an improvement of 6.9% in the F1 measure from traditional recommendation system techniques.

Progress and Prospect of Bimetallic Oxides for Sodium-Ion Batteries: Synthesis, Mechanism, and Optimization Strategy.

Sodium-ion batteries (SIBs) are considered as an alternative to and even replacement of lithium-ion batteries in the near future in order to address the energy crisis and scarcity of lithium resources due to the wide distribution and abundance of sodium resources on the earth. The exploration and development of high-performance anode materials are critical to the practical applications of advanced SIBs. Among various anode materials, bimetallic oxides (BMOs) have attracted special research attention because of their abundance, easy access, rich redox reactions, enhanced capacity and satisfactory cycling stability. Although many BMO anode materials have been reported as anode materials in SIBs, very limited studies summarized the progress and prospect of BMOs in practical applications of SIBs. In this review, recent progress and challenges of BMO anode materials for SIBs have been comprehensively summarized and discussed. First, the preparation methods and sodium storage mechanisms of BMOs are discussed. Then, the challenges, optimization strategies, and sodium storage performance of BMO anode materials have been reviewed and summarized. Finally, the prospects and future research directions of BMOs in SIBs have been proposed. This review aims to provide insight into the efficient design and optimization of BMO anode materials for high-performance SIBs.

Identifying the Optimal Area Threshold of Mapping Units for Cultural Ecosystem Services in a River Basin

Mapping cultural ecosystem services (CES) in river basins is crucial for spatially identifying areas that merit conservation due to their significant CES contributions. However, precise quantification of the appropriate area of mapping units, which is the basis for CES assessment, is rare in existing studies. In this study, the optimal area threshold of mapping units (OATMU) identification, consisting of a multi-dimensional indicator framework and a methodology for validation, was established to clarify the boundary and the appropriate area of the mapping units for CES. The multi-dimensional indicator framework included geo-hydrological indicator (GI), economic indicator (EI) and social management indicator (SMI). The OATMU for each indicator was determined by seeking the inflection point in the second-order derivative of the power function. The minimum value of the OATMU for each indicator was obtained as the OATMU for CES. Finally, the OATMU for CES was validated by comparing it with the area of administrative villages in the river basin. The results showed the OATMU for CES was 3.60 km2. This study adopted OATMU identification, with easy access to basic data and simplified calculation methods, to provide clear and generic technical support for optimizing CES mapping.

Pecipaw (Peci Angpaw): Adding a Wallet in Traditional Peci with Enhancement of Betawi Gigi Balang Ornament

This paper sets out the additional value of peci, a hat usually worn by Muslim males in Jakarta during the celebration of Eid al-Fitr, as a symbol of Indonesian cultural identity and modesty. It is common practice for individuals to store money (angpau) in the peci for easy access, however, there is a problem with the existing traditional peci design. Money will scatter when the peci falls off, thus, compromising user comfort and safety. The peci design was explored by introducing an additional wallet feature with a zipper that allows customization and versatility. Additionally, the use of Betawi traditional ornaments further enhances the peci value, making it suitable as an iconic souvenir from Jakarta. This research applied the design thinking approach of the Hasso Platner Institute (HPI) Stanford model with five steps comprised of empathize, define, ideate, prototype, and test as a problem-solving tool to provide a better understanding of the needs and perspectives of peci users. The results show that pecipaw innovation could cater to the added value of traditional peci products as an iconic souvenir of Jakarta. Further research will help to expand more explorative design and conduct user evaluation to establish objective measurements of the final prototype.

CAN Interceded Oxidative Coupling of β‐Dicarbonyl Compounds to 2‐Aryl/Heteroarylchromenes: A Regio‐ and Diastereoselective Synthesis of Tetrahydro‐benzofuro[3,2‐c]chromenones

AbstractA promising and useful method has been accomplished for regio‐ and diastereoselective synthesis of tetrahydro‐benzofuro[3,2‐c]chromenones through ceric(IV) ammonium nitrate (CAN) mediated oxidative coupling of cyclic/acyclic 1,3‐dicarbonyl compounds to 2‐aryl/heteroarylchromenes followed by a base assisted cyclization. The significant features of the method encircle easy accessibility of the starting materials, high air stability and low toxicity of oxidant CAN, high product yield, operationally simple and eco‐friendly reaction conditions. Trapping of a radical intermediate with radical scavenger TEMPO (detected by LC–MS) from the reaction mixture proved that the oxidative coupling is a radical mediated process.

Mental and Physical Symptoms and Perceived Health Risks of Pregnant and Postpartum Women following the Significant Shift in COVID-19 Management in China: A Cross-Sectional Survey

Background. There was a remarkable downgrade in China’s COVID-19 response strategies in January 2023. The COVID-19 infection rate grew rapidly in the early stages following the management policy shift. This study attempted to explore the associations between SARS-CoV-2 infection and mental or physical health status in pregnant and postpartum women and the role of perceived health risks and family members’ SARS-CoV-2 infection status on these associations by capturing the impact of policy shifts in a short period of time. Methods. This cross-sectional study with a random sample from a convenience sample of hospitals was conducted in pregnant and postpartum women in January 2023. Standardized assessment tools were employed to assess anxiety, depressive and physical symptoms, and feelings of hopelessness. Hierarchical multiple logistic regressions were conducted to examine the mechanisms of associations of interests by including a range of sociodemographic factors, self-perceived health, SARS-CoV-2 infection status, and perceived health risks as covariates. Results. Of the 1,013 pregnant and postpartum women aged 32.0 ± 0.3 years, 58.2% (n = 590) were diagnosed with COVID-19, and 49.4% (n = 500) had family members who were infected with SARS-CoV-2. Nearly 98% of the included participants took measures to prevent SARS-CoV-2 infection. A COVID-19 diagnosis was positively associated with feelings of hopelessness (OR = 1.68, 95% CI: 1.20–2.35), probable anxiety (OR = 6.42, 95% CI: 2.18–24.61), possible depression (OR = 2.56, 95% CI: 1.07–6.70), and physical symptoms (OR = 6.28, 95% CI: 1.63–42.03) after adjusting for sociodemographic and health characteristics, while the associations presented no statistical significance when family members’ SARS-CoV-2 infection status and perceived health risks were introduced into the models. Conclusions. Our results suggested that pregnant and postpartum women may experience physical and mental health challenges when they or their family members contracted COVID-19 in the context of a considerable shift in COVID-19 management. Early detection of poor health status and its risk factors for vulnerable groups during shifts in health policy and administrative practice is very necessary, and health services, including easy access to psychosocial support and obstetric counselling, should be prioritized.

Impact of end‐capped engineering on the optoelectronic characteristics of pyrene‐based non‐fullerene acceptors for organic photovoltaics

AbstractPyrene‐based molecules are being explored as prospective fullerene‐free acceptors for organic solar cells (OSCs), due to their easy accessibility, structural planarity, and excellent electron delocalization. In this work, we successfully designed and analyzed pyrene‐based acceptor materials (QL1–QL8) to investigate their photophysical and electro‐optical parameters. Various geometric parameters were computed at the MPW1PW91/6‐31G(d,p). Advanced quantum chemical approaches were employed to characterize the molecules. All the tailored molecules (QL1–QL8) exhibit a lower bandgap than the reference (R), signifying their superiority. Among these, QL8 was found to have a maximum absorption (λmax) at 791.37 nm and an optical bandgap (ELUMO − EHOMO) minimum of 2.11 eV. Redshifted absorption spectra are observed in both gaseous and solvent phases for all the designed (QL1–QL8) molecules in contrast to R. Among these, QL4 exhibits the highest light harvesting efficiency (0.9826), and open‐circuit voltage. A detailed donor–acceptor investigation of QL8/PBDB‐T revealed the marvelous charge switching at the donor–acceptor interface. The approach used in this study is anticipated to facilitate the manufacturing of highly efficient OSC molecules.

Antibiotic prescribing patterns and carriage of antibiotic-resistant Escherichia coli and Enterococcus species in healthy individuals from selected communities in Lusaka and Ndola districts, Zambia.

This study assessed antibiotic prescribing patterns in primary healthcare facilities and antimicrobial resistance (AMR) profiles of commensal Escherichia coli and enterococci isolated from pregnant women and children under 5 years of age. This cross-sectional study was conducted in Lusaka and Ndola districts of Zambia. Prescription pattern data were obtained from hospital pharmacies. Identification and antimicrobial susceptibility profiles of E. coli and enterococci were determined by conventional methods, while confirmation of both pathogens and AMR genes were determined by PCR. Data were analysed using WHONET and SPSS version 25.0. Most prescribed antibiotics at the primary healthcare facilities belonged to the Access group of the WHO Access, Watch and Reserve (AWaRe) classification. All the primary healthcare facilities adhered to the AWaRe framework of ≥60% prescribed antibiotics belonging to the Access group. However, resistance was highest in the Access group of antibiotics. E. coli resistance to ampicillin ranged from 71% to 77% and to co-trimoxazole from 74% to 80%, while enterococcal resistance to tetracycline was 59%-64%. MDR was highest in E. coli (75%) isolates, while XDR was highest in enterococcal isolates (97%). The identified AMR genes in E. coli included blaCTX-M, sul2 and qnrA, while those of enterococci included erm(B), erm(C) and erm(A). Resistance was highest in the prescribed WHO Access group of antibiotics. These findings highlight the need to use local susceptibility data to formulate country-specific treatment guidelines in line with WHO AWaRe classification and enforce regulations that prohibit easy access to antibiotics.

The peroxidase-like activity of Au NPs deposited inverse opal CeO2 nanozyme for rapid and sensitive H2O2 sensing

In this study, the hybrid nanozyme gold nanoparticles deposited CeO2 inverse opal photonic crystals (IOPCs) on the glass slide was fabricated by bestowing the hybrid with the beneficial porous morphology with its unique advantages: its surface valence states, high surface area, and copious active sites. The oxidase and peroxidase-mimicking activity was studied by observing the catalytic oxidation of chromogenic substrate 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid (ABTS) in the presence of H2O2, which can be visualized by the eyes. Au NPs and CeO2 IOPCs consisting of Ce3+ and Ce4+ can oxidize ABTS in the presence of H2O2 by mimicking peroxidase enzymes. The peroxidase-like activity of nanozyme was substantially improved by introducing light irradiation due to the photosensitive nature of the hybrid. The peroxidase-like activity of nanozyme enabled H2O2 linear detection over the range 9 to 500 μM, with a LOD of 2.7 µM. The acceptable nanozyme activity is probably owing to the easy access of H2O2 to the active sites of nanozyme. The porous architecture led to the easy channeling of reactants and products. The periodic architecture of the nanozyme also led to decent reproducibility. Without functionalization, the nanozyme can be a promising alternative to peroxidase enzymes for hydrogen peroxide measurements.

Efficient Solar-Driven Interfacial Water Evaporator using Hydrogel Modified Carbon-Based Biomass with Abundant Microchannels.

The conventional sea water desalination technologies are not yet adopted worldwide, especially in the third world countries due to their high capital cost as well as large energy requirement. To solve this issue in a sustainable way an interfacial solar water evaporation device is designed and proposed in this article using the branches of Prunus serrulata (PB). The PB has abundant microchannels and shows excellent photothermal conversion capability after carbonization. Moreover, the easy access to raw materials and the facile fabrication process makes the solar water evaporating device very cost effective for seawater desalination application. Experiments show that in the presence of the fabricated evaporator the evaporation rate of water can reach 3.5kgm-2h-1 under 1 sun, which is superior to many similar experimental devices. In addition, its advantages, such as effective sewage purification capability, low cost, and environmental friendliness, make this evaporator highly competitive in the extensive promotion of this technology and can be considered as a new sustainable solution for seawater desalination with great application potential and prospects.

Gasless robot-assisted transaxillary hemithyroidectomy (RATH): learning curve and complications

PurposeGasless robot-assisted transaxillary hemithyroidectomy (RATH) is regarded as an alternative surgical option for thyroid operations. However, the associated steep learning curve is a clinical concern. This study evaluated the learning curve of RATH for surgeons without experience of endoscopic surgery and the early surgical outcomes of RATH.MethodsWe conducted a retrospective study of patients who underwent gasless RATH and conventional hemithyroidectomy (CH) at Sun Yat-sen University Cancer Center, Guangzhou, China, from June 2021 to August 2022. The learning curve and early surgical outcomes of gasless RATH were evaluated. And the early surgical outcomes of gasless RATH were compared to CH.ResultsIn total, 105 patients who underwent gasless RATH and 104 patients who underwent CH were matched and assessed. The cumulative sum techniques (CUSUM) analysis showed that the peak point of gasless RATH operative time occurred at the 31st case. No clear single peak was identified in the CUSUM plot for drainage amount and blood loss. No significant difference in perioperative complications was observed between these two groups. Moreover, the number of postoperative patients who got sense of thyroid area traction were fewer in the gasless RATH group (n = 11, 10.5%) than in the CH group (n = 32, 30.8%).ConclusionGasless RATH can be considered as an alternative approach to the conventional open procedure, as it is an easy remote access technique, with shorter learning curves and certain advantage such as less sense of thyroid area traction.

Preventing zoonotic and zooanthroponotic disease transmission at wild great ape sites: Recommendations from qualitative research at Bwindi Impenetrable National Park.

Employees at wild great ape sites are at high risk of transmitting infectious diseases to endangered great apes. Because of the significant amount of time employees spend near great apes, they are a priority population for the prevention and treatment of zoonotic and zooanthroponotic spillover and need adequate preventive and curative healthcare. Qualitative, semi-structured interviews with 46 staff (rangers and porters) at Bwindi Impenetrable National Park, Uganda (BINP) and key informants from five other wild great ape sites around the world were performed. The objectives of the study were to 1) evaluate health-seeking behavior and health resources used by staff in contact with great apes at Bwindi Impenetrable National Park; 2) evaluate existing occupational health programs for employees working with great apes in other parts of the world; and 3) make recommendations for improvement of occupational health at BINP. Results show that BINP employees do not frequently access preventive healthcare measures, nor do they have easy access to diagnostic testing for infectious diseases of spillover concern. Recommendations include assigning a dedicated healthcare provider for great ape site staff, providing free annual physical exams, and stocking rapid malaria tests and deworming medication in first aid kits at each site.

A miniaturized culture platform for control of the metabolic environment.

The heart is a metabolic "omnivore" and adjusts its energy source depending on the circulating metabolites. Human cardiac organoids, a three-dimensional in vitro model of the heart wall, are a useful tool to study cardiac physiology and pathology. However, cardiac tissue naturally experiences shear stress and nutrient fluctuations via blood flow in vivo, whilst in vitro models are conventionally cultivated in a static medium. This necessitates the regular refreshing of culture media, which creates acute cellular disturbances and large metabolic fluxes. To culture human cardiac organoids in a more physiological manner, we have developed a perfused bioreactor for cultures in a 96-well plate format. The designed bioreactor is easy to fabricate using a common culture plate and a 3D printer. Its open system allows for the use of traditional molecular biology techniques, prevents flow blockage issues, and provides easy access for sampling and cell assays. We hypothesized that a perfused culture would create more stable environment improving cardiac function and maturation. We found that lactate is rapidly produced by human cardiac organoids, resulting in large fluctuations in this metabolite under static culture. Despite this, neither medium perfusion in bioreactor culture nor lactate supplementation improved cardiac function or maturation. In fact, RNA sequencing revealed little change across the transcriptome. This demonstrates that cardiac organoids are robust in response to fluctuating environmental conditions under normal physiological conditions. Together, we provide a framework for establishing an easily accessible perfusion system that can be adapted to a range of miniaturized cell culture systems.

Influence of storage temperature and natural antioxidants addition on chia oil nutraceutical blends shelf life

AbstractThis study focuses on the influence of storage temperature and addition of commercial natural antioxidant‐rich sources on the shelf life of chia oil (CO) nutraceutical blends. CO is a valuable product for consumers due to its high ω‐3 content, but its susceptibility to oxidation comprises challenges for its shelf life and quality. Thereby, different chia oil‐antioxidant blends were prepared and stored at 4°C and 25°C to evaluate alternative shelf‐life conditions. Commercial antioxidant‐rich sources containing astaxanthin (ASX), β‐carotene (BC) and vitamin E (VE) were added either alone or combined to CO. To monitor blends oxidative stability during storage, primary and secondary oxidation compounds were assessed weekly using peroxide value (PV) and thiobarbituric acid reactive substances (TBARS) as indicators. Results showed that storage temperature played a significant role on oxidative stability of CO. When stored under refrigeration at 4°C, the oil exhibited low and stable oxidation indicators over time, regardless of the antioxidants used. However, at room temperature (25°C), the use of antioxidants and some particular combinations of them became crucial to prevent oil oxidative deterioration. Nutraceutical blends of CO/BC and CO/ASX were the best options to preserve CO from oxidation after 8 weeks storage at room temperature (PV < 2 meq O2/kg oil).Practical Applications: This work provides evidence on enhancing oxidative stability of chia oil through addition of natural antioxidants and proper storage. We focused primarily on designing blends from edible ingredients that are currently available in the market, with the aim of ensuring easy accessibility and affordability. Our findings offer valuable insights for the development of chia oil and antioxidant‐enriched blends, that could potentially serve as nutraceuticals or pharmacy‐compounded supplements to manage specific chronic inflammatory diseases. Our study highlights the importance of considering storage temperature and antioxidant selection to enhance shelf life and quality. These results have significant implications for the food industry, nutrition, and health, by providing valuable information for the creation of healthier and more sustainable food products. Furthermore, this work underscores the need for companies and retailers handling and storing vegetable oils with high omega‐3 content to adopt improved storage practices to ensure the quality and longevity of their products.

Reviewing the Potential Role of Artificial Intelligence in Delivering Personalized and Interactive Pain Medicine Education for Chronic Pain Patients.

The integration of artificial intelligence (AI) in patient pain medicine education has the potential to revolutionize pain management. By harnessing the power of AI, patient education becomes more personalized, interactive, and supportive, empowering patients to understand their pain, make informed decisions, and actively participate in their pain management journey. AI tailors the educational content to individual patients' needs, providing personalized recommendations. It introduces interactive elements through chatbots and virtual assistants, enhancing engagement and motivation. AI-powered platforms improve accessibility by providing easy access to educational resources and adapting content to diverse patient populations. Future AI applications in pain management include explaining pain mechanisms, treatment options, predicting outcomes based on individualized patient-specific factors, and supporting monitoring and adherence. Though the literature on AI in pain medicine and its applications are scarce yet growing, we propose avenues where AI may be applied and review the potential applications of AI in pain management education. Additionally, we address ethical considerations, patient empowerment, and accessibility barriers.

A direct Monte Carlo approach for the modeling of neutrals at the plasma edge and its self-consistent coupling with the 2D fluid plasma edge turbulence model HESEL

This paper presents a novel coupling of a kinetic description of neutrals with a fluid description of a fusion plasma. The code, plasma interacting super-atoms and molecules (PISAM), employs a grid-free Cartesian geometry and a direct simulation Monte Carlo approach to solve the kinetic equations of deuterium atoms and molecules. The grid-free geometry and the parallel nature of the neutral dynamics, in the absence of neutral–neutral interactions, allow for an unlimited and work-efficient parallelization of PISAM that always ensures a balanced workload. The highly optimized Python implementation obtains good performance while securing easy accessibility to new users. The coupling of PISAM with the edge turbulence model HESEL is outlined with emphasis on the technical aspects of coupling Message Passing Interface-parallelized Python and C++ codes. Furthermore, the paper presents and analyzes simulation results from running the coupled HESEL-PISAM model. These results demonstrate the impact of radial neutral transport and plasma–neutral dynamics perpendicular to the magnetic field. Specifically, they illustrate how the inward flow of neutral kinetic energy and the inhibition of radial electric shear, resulting from poloidal momentum transfer between atoms and ions, can affect the energy containment time. By comparing the results of the HESEL-PISAM model with those obtained from coupling HESEL with a diffusive-fluid-neutral model, the capabilities of diffusion models in predicting neutral transport in the plasma edge and scrape-off layer are elucidated.
