Evaluation of Traffic Efficiency and Energy-Saving Benefits of L3 Smart Vehicles under the Urban Expressway Scenario

An L3 smart vehicle (L3 SV) could behave differently from human-driven vehicles due to its intelligent configuration and decision-making logic, and may consequently exert influences on traffic flow. In order to clarify the L3 SV’s traffic impacts and accelerate L3 SV implementation, this paper conducted an evaluation on the traffic efficiency and energy consumption influences of L3 SVs based on a microscopic traffic simulation. Taking Beijing as a case, the relevant traffic economic benefits were calculated with the help of the previously proposed traffic economic benefits model. Before modeling L3 SVs, a two-dimensional general modeling architecture for SVs was proposed. According to the architecture, the driving behavior model, as well as behavior selection models of L3 SVs, was eventually determined, based on which the intelligent driving model of L3 SVs was established. Urban expressways were selected as the simulation road type, and scenario analysis was conducted on various proportions of L3 SVs and L3 connected and autonomous vehicles (L3 CAVs), as well as the input traffic flow rates. It was found that L3 SVs can significantly reduce the travel time and energy consumption and enlarge the actual road capacity. The improvement will become particularly prominent under saturated or supersaturated traffic flow and increasing the proportion of L3 SVs and L3 CAVs can also amplify the effect of traffic optimization. The related economic benefit is considerable, which is CNY 3.104 billion a year based on Beijing’s travel and traffic conditions.

Evaluation of Reciprocal Benefits of Green Manure on Yield and Nutrient Composition of Sorghum almum Hay and Silage

The increasing cost of inorganic fertilizer and concerns for more ecological stability with sustainable soil fertility have led to a renewed interest in green manuring, which is affordable and more environmental friendly soil management practice. This experiment was undertaken to evaluate the reciprocal benefits of green manure on yield and nutritive value of Sorghum almum. The experiment was conducted in two phases. First experiment evaluated the yield, morphological characteristics and quality of hay while the second phase assessed the fermentation characteristics and quality of silage. The experiment design was 1x5 factorial arrangement in a split plot design and replicated three times. Three legume species: Centrosema poscurum, Lablab purpureum and Glycine max were used as sources of green manure and a positive control (Urea, Single Super Phosphate and Muriate of Potash at rate of 100, 50, 50 kg/ha, respectively) and negative control (0 k/ha). Data obtained were subjected to analysis of variance (ANOVA) at P= 0.05. The results showed Significant (P<0.05) increase in values of soil pH, phosphorus, organic carbon, potassium and total nitrogen as influenced by green manure compared to Negative control. Higher significant (P<0.05) Dry matter yield among legumes was recorded when Centrosema pascourum was used to grow Sorghum almum (8.31t/ha). However, positive control recorded the highest values (9.07t/ha). The same trend was observed in terms of plant height (101.90 cm), leaf length (53.47cm) and leaf width (1.93cm). Proximate composition CP (8.75%) DM (98.13%), Ash (8.58%) and NFE (47.90%) of the grass were significantly (P<0.05) higher while fiber fractions NDF (40.42) and ADF (24.72) reduced when Centrosema pascuorum was used compared to other sources of green manure. However, positive control recorded highest proximate values with minimum fiber fractions. Silage fermentation characteristics revealed that quality silage was produced. Silage proximate composition and fiber fractions of Sorghum almum showed similar trend as hay. Conclusively, Centrosema pascourum proves to be the best source of green manure and is therefore recommended for cultivation Sorghum almum in the study area. Le coût croissant des engrais inorganiques et les préoccupations concernant une plus grande stabilité écologique et une fertilité durable des sols ont conduit à un regain d'intérêt pour l'engrais vert, qui constitue une pratique de gestion des sols abordable et plus respectueuse de l'environnement. Cette expérience a été entreprise pour évaluer les bénéfices réciproques de l'engrais vert sur le rendement et la valeur nutritive du Sorghum almum. L'expérience s'est déroulée en deux phases. La première expérience a évalué le rendement, les caractéristiques morphologiques et la qualité du foin tandis que la deuxième phase a évalué les caractéristiques fermentaires et la qualité de l'ensilage. Le plan d'expérience était un arrangement factoriel 1x5 dans un plan en parcelles divisées et répliqué trois fois. Trois espèces de légumineuses : Centrosema poscurum, Lablab purpureum et Glycine max ont été utilisées comme sources d'engrais vert et comme témoin positif (Urée, Super Phosphate Simple et Muriate de Potasse à raison de 100, 50, 50 kg/ha, respectivement) et témoin négatif. (0k/ha). Les données obtenues ont été soumises à une analyse de variance (ANOVA) à P = 0,05. Les résultats ont montré une augmentation significative (P <0,05) des valeurs du pH du sol, du phosphore, du carbone organique, du potassium et de l'azote total sous l'influence de l'engrais vert par rapport au contrôle négatif. Un rendement en matière sèche plus élevé et significatif (P< 0,05) parmi les légumineuses a été enregistré lorsque Centrosema pascourum a été utilisé pour cultiver du Sorghum almum (8,31 t/ha). Cependant, le contrôle positif a enregistré les valeurs les plus élevées (9,07 t/ha). La même tendance a été observée en termes de hauteur des plantes (101,90 cm), de longueur des feuilles (53,47 cm) et de largeur des feuilles (1,93 cm). La composition immédiate CP (8,75 %) DM (98,13 %), cendres (8,58 %) et NFE (47,90 %) de l'herbe était significativement (P < 0,05) plus élevée tandis que les fractions de fibres NDF (40,42) et ADF (24,72) étaient réduites lorsque Centrosema pascuorum a été utilisé par rapport à d'autres sources d'engrais vert. Cependant, le contrôle positif a enregistré les valeurs immédiates les plus élevées avec des fractions de fibres minimales. Les caractéristiques de fermentation de l'ensilage ont révélé qu'un ensilage de qualité était produit. La composition immédiate de l'ensilage et les fractions de fibres du Sorghum almum ont montré une tendance similaire à celle du foin. En conclusion, Centrosema pascourum s'avère être la meilleure source d'engrais vert et est donc recommandé pour la culture du Sorghum almum dans la zone d'étude.

Funding of evidence included within public comments submitted to inform Medicare national coverage determinations.

The Centers for Medicare & Medicaid Services (CMS) relies on public comments submitted in response to proposed national coverage determinations to assist the agency in determining the coverage of items and services for Medicare beneficiaries. In a cross-sectional study, we characterized the cited evidence and what funding supported the cited evidence submitted in public comments to CMS for all therapeutic medical device national coverage determinations finalized between June 2019 and June 2022. Of 681 public comments, 159 (23%) cited at least 1 identifiable published scientific journal article. Within these 159 public comments, 198 unique articles were cited, 170 (86%) of which included funding statements or author disclosures. Among these, 96 (56%) disclosed funding from manufacturers that would benefit from Medicare coverage and/or were written by author(s) who received funding from these manufacturers. In summary, most public commenters for national coverage determinations did not cite published scientific journal articles to support their positions. Among those who did, more than half of articles were directly funded by manufacturers that would benefit from coverage. Greater funding of independent, non-industry-supported research may help provide unbiased evaluations of benefits and harms to support Medicare coverage decisions.

An early economic evaluation of Kooth, a web-based mental health platform for children and young people with emerging mental health needs

Background“Kooth” is a web-based mental health platform commissioned by the National Health Service (NHS), local authorities, charities, and businesses in the UK. The platform gives children and young people (CYP) access to an online community of peers and a team of counsellors. This study reports an early economic evaluation of the potential benefits of Kooth in the UK. MethodsAn early evidence cost calculator was built to estimate the potential costs and savings of implementing Kooth from a UK NHS and crime sector perspective. A decision tree structure was used to track the progress of CYP with emerging mental health needs (EMHN), comparing CYP with access to Kooth to CYP without access to Kooth. The model implemented a 12-month time horizon and followed a typical Kooth contract in relation to costing, engagement, and CYP demographics. ResultsThe base case results followed a cohort of 2160 CYP. The results of the cost calculator estimated that engagement with Kooth is associated with a cost saving of £469,237 to the NHS across a 12-month time horizon, or £236.15 per CYP with an EMHN. From a combined NHS and UK crime sector perspective, the cost savings increased to £489,897, or £246.54 per CYP with an EMHN. The largest cost savings were provided by an estimated reduction of 5346 GP appointments and 298 antidepressant prescriptions. For this cohort, the model predicted that engagement with Kooth averted 6 hospitalisations due to suicidal ideation and 13 hospitalisations due to self-harm. Furthermore, the number of smokers and binge drinkers was reduced by 20 and 24, respectively. When a crime sector perspective was taken, 3 crimes were averted. DiscussionThis early model demonstrates that Kooth has the potential to be a cost-saving intervention from both an NHS and a combined NHS and UK crime sector perspective. Cost savings were provided through aversion in clinical and social outcomes. The model used a conservative approach to balance the uncertainty around assumptions of the intermediate outcomes (GP and medication use). However, it is limited by a paucity of costing data and published evidence relating to the impact of digital mental health platforms.

Evaluation of energy performance and ecological benefit of free-cooling system for data centers in worldwide climates

Water-side economizer (WSE) is an effective free-cooling solution aiming to enhance the natural cooling duration and in turn reduce the cooling-energy consumption of data centers. However, the system's performance is constrained by the limited understanding of its control mechanisms and the influence of local climatic conditions on its free-cooling capabilities. To overcome these limitations, a thermodynamic model of the WSE system with control strategies is provided and its adaptability performance in diverse worldwide locations is systematically evaluated. Modelica-based models of chiller plants and control strategies are firstly developed, and then the energy consumption and ecological benefit of the WSE system are investigated via large-scale simulations in worldwide climates. The performance indicators and application potential of the system are demonstrated through visualization maps. The analysis reveals significant energy savings potential of the WSE system, with the capacity to reduce annual cooling energy consumption of data centers by 4.4–33.7 % in hot to marine zones, and even by a remarkable 62.6 % in plateaus and cold zones. Furthermore, it is observed that every 1 °C increase in outdoor air temperature can reduce energy efficiency ratio by 1.3–8.7 % while simultaneously increase PUE by 0.3–1.0 %. The ecological benefit results revealed that the WSE system can effectively harness larger quantities of stable free-cooling resources in mixed and cool climate zones, exceeding its capabilities in hot and warm regions. These results offer valuable insights for the impact of climate on the energy and ecological benefits of WSE system for data center, which can be helpful to guide the design or retrofit of such cooling systems in specific locations, presenting an immense opportunity to maximize cooling-energy savings.

Balancing Bioethics and Legal Frontiers: А Case Study of Brazil’s Supreme Federal Court Decision on Embryonic Stem Cell Research

Background. The present work focuses on the need to protect prenatal life, which is intricately entwined with delineating the precise biological and legal juncture marking an embryo’s transition into personhood. Drawing upon bioethical insights from domestic frameworks and international jurisprudence, we compare diverse perspectives on the moral and legal standing of the embryo, including its right to life, and invoking legal principles in the context of cellular and regenerative medicine.Aim. The goal of this article is to investigate the various biosafety policy approaches governing embryonic stem cell research, ranging from outright prohibition to authorization solely for therapeutic or scientific ends. Through our analysis, we focus on the unique national context of Brazil to scrutinize the underlying rationale behind a specific legal challenge questioning the constitutionality of the BiosafetyLaw. This law, which permits the utilization of human embryonic cells for research and therapeutic purposes, raises concerns about potential infringement upon the inviolability of the right to life.Methodology. The research is based on deductive reasoning alongside formal-legal methodologies, including textual interpretation and comparative-legal analysis. The research process involved documentary, bibliographic, and virtual analytical inquiries utilizing a variety of resources such as legislative texts, monographs, academic articles, databases, and online libraries. Results. Through our examination in a distinct national context, we delineate the theoretical-philosophical and normative-ethical foundations underpinning the stances of Brazilian Supreme Court justices concerning the utilization of embryonic stem cells. Their arguments predominantly invoked significant constitutional liberties such as freedom of family planning, scientific research, and academic pursuits, intertwined with considerations of human dignity and the sanctity of life. Additionally, some justices cautioned against the potential hazards inherent in genetic manipulation.Implications. The legal and ethical ramifications of Brazil’s approach to biosafety legislation concerning embryo rights invoke the necessity for conducting neutral, unfettered scientific inquiry and regenerative therapies according to specific operational parameters. These include safeguarding the integrity of genetic inheritance, preemptive evaluation of potential risks and benefits (adherence to the precautionary principle), and ensuring informed consent for treatments. A significant hurdle consists in the need to establish robust mechanisms for overseeing research involving human embryos within the domains of biomedicine and regenerative cell therapy

Quantitative Study on the Social Benefit of Medical Devices

The performance status of large medical device is one of the core driving forces behind hospital operations and development, and its importance is self-evident. It involves the economic benefits of hospitals-by improving diagnostic and treatment efficiency, reducing costs, and directly contributing to fiscal revenue, but it also profoundly affects the social benefits of hospitals. These social benefits include improving the quality of medical services, increasing patient satisfaction, and building public trust, all of which contribute intangible value. These positive social benefits effectively attract more patients, which in turn becomes a potential driver for long-term hospital development and a growth point for economic benefits. This paper innovatively applies the Fuzzy Analytic Hierarchy Process (FAHP) to address the challenge of quantifying the social benefits of large medical device. It achieves a comprehensive and precise evaluation of both economic and social benefits. The introduction of this method provides hospital device managers with a more thorough and in-depth insight into device performance, enabling data-driven decision-making and more refined and scientific management. Through data-driven management optimization, hospitals can further enhance operational efficiency, strengthen competitiveness, provide higher quality and more efficient medical services to patients, and lay a solid foundation for their own sustainable development.

Evaluation of the Possible Benefits of Breast Cancer Screening in Women Aged 40 to 49 Years in the Steel Valley Region, Brazil

Background: This study investigates the effectiveness of mammographic screening for women aged 40 to 49 in Brazil's Steel Valley Region. Despite a Ministry of Health recommendation to start screenings at 50, 25% of breast cancer cases occur in the 40-49 age group. Methods: The retrospective analysis, spanning 2008-2019 at Marcio Cunha Hospital, compared two groups: cancer diagnosed via screening mammography (277) and diagnostic mammography (229). Results: Results showed delayed diagnoses for non-screened women, with 4.16 times higher mortality rate. Screening facilitated earlier detection of less malignant cancers (85.9% vs. 43.7%). Women diagnosed through screening were more likely to preserve their breasts (28.9% vs. 55.5% for Radical Breast Surgery and 71.1% vs. 28.9% for Breast-Sparing Surgery), and fewer axillary lymphadenectomies were performed. All statistical tests performed returned a p-value lower than 0.05 showing high statistical significance. Conclusion: The findings support extending screening mammography access to all women over 40 in the Steel Valley region and underscore the need for broader-scale research in other areas. Recommendations include enhancing public awareness and establishing a breast cancer surveillance service.

A Scale for Measuring Positive and Negative Experiences of Psychotherapy (PNEP): First Psychometric Findings of a New Instrument for Monitoring Clients' Experiences.

Clients' adverse experiences during psychotherapy are rarely monitored in clinical practice or research trials. One obstacle here is the lack of a measure to gauge both positive and negative experiences during psychotherapy. We developed and evaluated a new instrument for measuring such experiences. The Positive and Negative Experiences of Psychotherapy (PNEP) questionnaire was developed based on pilot data, a literature review, and two existing scales for measuring primarily adverse experiences during psychotherapy. Mental healthcare clients (N = 200) anonymously completed and evaluated the PNEP. Subsequently, a sample of professionals (N = 34) who underwent psychotherapy in the context of their training filled in the PNEP twice, with a 2-week interval in between. The positive and negative experiences subscales of the PNEP were found to possess excellent internal consistencies (αs ≥ 0.90). The PNEP test-retest reliability was 0.93 for the positive experiences subscale and 0.78 for the negative experiences subscale. For the positive subscale, four factors were extracted: symptom reduction and positive well-being, high quality of therapy and therapeutic relation, personal growth and acceptance and interpersonal functioning. For the negative subscale, exploratory factor analysis suggested a three-factor solution: escalation of symptoms and emotional distress, low quality of therapy and therapeutic relation and (self-)stigmatization and dependency. Participants related a median of 13 positive and six negative therapy experiences to their most recent treatment. The most frequently endorsed negative experiences were having more negative thoughts and memories, feeling emotionally overwhelmed and an increase in stress due to the therapy. A minority of participants (10.5%) reported no negative treatment experiences. In the field of psychotherapy, the evaluation of risks and benefits is crucial for assessing safety and effectiveness. The PNEP could be a promising instrument for achieving this objective, although further research is needed to replicate and expand upon the current findings.

Experimental investigation on the potential of passive prechambers for use in 2S engines

Design improvement of Internal Combustion Engines (ICEs) is required by the continuous update of European exhaust emission standards and vehicle registration protocols. This has pushed research and industry efforts towards the development of Low Temperature Combustion (LTC) systems. Among various LTC technologies, the so called “jet ignition” is claimed to be well-suited for light engines, since it provides a more uniform and rapid combustion while ensuring the mixture ignition process. In this context, the adoption of prechambers was found well-suited for two-stroke engines, for which low-pressure direct injection technologies have been developed in the last decade to reduce the fuel short circuit phenomenon. The present paper experimentally investigates the use of different passive combustion prechambers in a Low-Pressure Direct Injection (LPDI) 2-stroke engine, with the main purpose to understand the relationship between prechamber geometrical parameters and engine performance. A 50-cc single cylinder LPDI motorcycle engine is chosen as the test case and it is re-arranged to run in jet ignition mode. The experimental analysis focuses on the evaluation of benefits provided by jet ignition combustion compared to the baseline LPDI propulsion unit at different engine operating points. Design criteria for prechambers development and the tuning process of engine combustion parameters (such as start of injection, ignition time and throttle valve opening) are described in detail. The results of experimental activity are finally shown and critically discussed, highlighting advantages and disadvantages of this application in terms of engine performance, efficiency and cycle-to-cycle variation.

Optimization of Frequency Modulation Energy Storage Configuration in Power Grid Based on Equivalent Full Cycle Model

This paper aims to meet the challenges of large-scale access to renewable energy and increasingly complex power grid structure, and deeply discusses the application value of energy storage configuration optimization scheme in power grid frequency modulation. Based on the equivalent full cycle model and a large number of actual operation data, various energy storage technologies are technically analyzed, and the economic and environmental performance of different energy storage configuration schemes are comprehensively evaluated. On this basis, this paper puts forward a set of efficient and economical energy storage configuration optimization strategies to meet the demand of power grid frequency modulation and promote the wide application of energy storage technology. After an in-depth analysis, it is found that the optimized energy storage configuration scheme is excellent in technology, economy, and environmental protection. Specifically, in terms of technical performance, the optimization scheme has significantly improved key indicators such as energy storage efficiency, capacity and power, and response speed, which can better meet the requirements of power grid frequency modulation. Through the verification of actual operation data, it is found that the overall efficiency of the optimized energy storage configuration scheme is above 55%, which is helpful to the stability and efficiency of power grid frequency modulation. In terms of economic performance, although the initial investment cost of the optimization scheme may be high, it is found that it has good economy through the evaluation of long-term operation benefits. Considering that the energy storage system can reduce the operating cost of the power grid, improve the energy utilization rate, and achieve the optimization of cost-effectiveness in the long run, this scheme is economically feasible and attractive. In terms of environmental performance, the optimization scheme effectively reduces the negative impact on the environment by improving energy storage efficiency, reducing emissions, and optimizing resource utilization. This is not only conducive to the sustainable development of the power grid but also in line with the current global trend of promoting green and low-carbon transformation. To sum up, this paper not only provides an efficient and economical energy storage allocation optimization strategy for power grid frequency modulation but also provides a scientific basis for relevant decision-making departments. By promoting the practical application and development of energy storage technology, this paper is helpful to improve the frequency modulation ability of power grid, optimize energy structure, and reduce environmental pollution, and thus achieve the goal of sustainable energy development. The data results and in-depth analysis of this paper provide strong support for the practical application of energy storage configuration optimization scheme and also provide important reference for the further innovation and development of energy storage technology.

Study on the Construction of Evaluation System of Cultivated Land Intensive Use in Different Spatial Scales

The sustainable intensive use of cultivated land(SIUCL) is a strategic demand to change theway of agricultural development and promote the construction of ecological civilization. The comparative analysis of different scales and the scale transformation, extension and integration has an important influence on the sustainable and intensive use of cultivated land. This paper summarizes the construction principles of the evaluation system, and combs the evaluation of cultivated land intensive use at different spatial scales. The results show that (1) The studies on the intensive use of cultivated land at the macro-scale are the most which mainly include provinces, urban agglomerations, watersheds, economic zones, etc.. The evaluation system of intensive use of cultivated land at the macro-scale has gradually expanded from the evaluation of input intensity and output benefit to the evaluation of input intensity, output benefit, utilization degree and sustainability status. (2) The studies on the intensive use of cultivated land at the median-scale are mainly include small and medium-sized cities, counties, etc.. The evaluation indexes of intensive use of cultivated land at the median-scale includes input intensity, output effect, utilization level and sustainable utilization status, which is consistent with macro-scale studies. But all the indicators are more comprehensive. (3) The studies on the intensive use of cultivated land at the micro-scale are mainly include towns, villages, farmers, plots, etc.. Among them, in the evaluation system of cultivated land intensive use at the farmer scale, the selection of indicators is very different from that of macro-scale and median-scale studies. Most of the data come from farmer interviews, questionnaires, etc.

Synthesis and characterization of modified iron oxide hydrophobic corrosion-resistant pigment for aluminum alloy coating

A hydrophobic coating containing modified iron oxides was prepared for corrosion protection of aluminum alloy. The modified iron oxide particles were synthesized using the annealing method and the evaluation of the corrosion-resistant benefits of modified iron oxides as additive in the epoxy resin coating was conducted. The raw FeOOH phase can be transformed into the α-Fe2O3 phase by increasing the annealing temperature. The morphology, colors, and pore size of the modified iron oxide are controllably evolved via finely adjusting the annealing temperature, which is beneficial for the compatibility, dispersion, and stability with epoxy resin. Besides, modified α-Fe2O3 annealed at 700 °C exhibited elliptical morphology and good solubility in epoxy resin solvents to form a hydrophobic corrosion inhibition layer (TP700), which further improves the corrosion resistance. Findings of corrosion electrochemical measurements and salt spray test confirmed the existence of TP700 composite coating resulted in the best corrosion protective properties on aluminum alloy during the corrosion process with the minimum corrosion current of 7.75 × 10−10 A cm−2 and the maximum |Z|0.01Hz value of 1.80 × 108 Ω cm2, which both are about two orders of magnitude higher than the commercial Fe2O3. Our results suggest a new venue for preparing modified iron oxide pigment on the surface of aluminum alloy materials for enhanced anti-corrosion applications.

Development of a scale for the impact of emotion management on young athletes’ training efficiency

In this study, we developed a scale to evaluate emotion management and its benefits for young athletes in China, and to analyze the impact of emotion management on their training efficiency. Following an extensive literature review, we used AMOS structural equation model software to develop a scale for evaluating the effects and benefits of emotion management on young athletes' training efficiency. Results showed that young athletes' emotion management training and its benefits can be divided into five dimensions: benefit evaluation, emotional cognition, emotion influence, emotion control, and emotion regulation. The internal consistency reliability of the formal scale was 0.895, and the internal consistency reliability of each subscale was between 0.734 and 0.901. The split-half reliability was 0.769, and the split-half reliability of each subscale was between 0.623 and 0.864. The KMO value was 0.904, P = 0.00 (p < 0.05), and the cumulative interpretation rate was 61.782 % of the total variance. The lowest factor load of a scale item was 0.436, and the highest factor load was 0.846. The common degree of all items was between 0.402 and 0.762, indicating that the scale has good validity. A SEM model verified that the scale has good construct validity. Significant correlational differences were observed among the levels. The results of the SEM structural equation model analysis showed that the model's NC = 2.660 (1 < NC < 3 indicates that the model has a simple fit), PGFI = 0.722, PNFI = 0.699, IFI = 0.851, PRA = 0.927, RMR = 0.006, and RMSEA = 0.07, thus, these indexes reached the standard of excellent model fitting. The strongest correlation was found between emotional cognition and benefit evaluation (R = 0.690), and the weakest correlation was found between emotion influence and benefit evaluation (R = 0.079). These findings provide a basis for measuring the effect of emotion management on training efficiency in the training process of young athletes and offer a theoretical reference for their emotional development while in training.

Representativeness of the PIONEER-HF and PARAGLIDE-HF in patients hospitalized with acute heart failure.

The PIONEER-HF and PARAGLIDE-HF trials aimed to determine the efficacy and safety of the in-hospital initiation of sacubitril/valsartan in patients hospitalized for AHF. However, whether the inclusion and exclusion criteria of the trials apply to patients encountered in real-world routine care is unclear. This study aimed to investigate the applicability of the PIONEER-HF and PARAGLIDE-HF trials to real-world AHF patients. We identified 28293 AHF hospitalized patients between August 2008 to August 2017 from the Chang Gung Research Database and classified them into four groups based on left ventricular ejection fraction (LVEF) and trial criteria. Cox proportional hazards models were used to compare the risk of HF hospitalization and cardiovascular (CV) death. We defined PIONEER-HF eligible (n=3683) and non-eligible (n=3502) patients with an LVEF ≤40%, and PARAGLIDE-HF eligible (n=5191) and non-eligible (n=5832) patients with an LVEF >40%. Over a mean follow-up of 3.5years, the PIONEER-HF non-eligible and eligible groups exhibited similar rates of HF hospitalization and CV death (41.1% vs. 41.8%, adjusted hazard ratio [aHR]: 0.95; 95% CI: 0.88-1.04). No significant difference was found in the composite outcome between PARAGLIDE-HF non-eligible and eligible groups (36.7% vs. 38.6%; aHR: 0.97; 95% CI: 0.90-1.04). Using trial criteria, only 31.3% of AHF patients were eligible for sacubitril-valsartan. Yet, non-eligible patients demonstrated similar outcomes to eligible patients, indicating a need for further evaluation of sacubitril-valsartan benefits in non-eligible AHF patients.

Farmers’ Adoption of Finger Millet Production Technologies and the Impact on Finger Millet Yields

Low remuneration and poor adoption of Finger millet [Eleusine coracana] production technologies were major constraints in yield gap in finger millet. Therefore, evaluation of production potential, adoption, economic and other benefits of the technologies in social perspectives of the farmers was undertaken. The study was conducted in two districts of Karnataka, India where the frontline demonstrations programme organized during the five years from 2017-18 to 2021-22 in 200 farmers’ fields. The knowledge, adoption and impact were measured by following before and after method, and data was collected through survey, focussed group discussion and personal interview methods. The demonstrated technologies resulted into increase in Knowledge over pre demo in use of high yielding variety (85%) followed by use of nitrogen (Urea) (62%), seed treatment (62%), use of FYM (56 %). Increase in adoption over pre demo was found in use of high yielding variety 82 % followed by use of nitrogen (62%), seed treatment (55%), use of FYM (48%). The higher adoption of the demonstrated technologies (71%) by the farmers in Karnataka led to higher grains production (33%) with better quality (65%) and fodder yield by 38% over pre-FLD stage. The increased yields not only enabled them to obtain higher net returns (55%) and incremental increase of benefit-cost ratio (25%) but also motivated to increase in area under finger millet (20%) significantly than the pre-FLD stage. Whereas, very low increase in cost of production (10%) over the pre-FLD stage was observed. Age, education, family size, annual income, institutional support, extension contact, herd size, and utility of grain and fodder were found to be significant in explaining the variation in their adoption level of demonstrated finger millet production technologies. Among the constraints, availability of labour, wild animals (deer and wild boar) and availability of seed are the major production constraints and price fluctuation, limited quantity purchases by government, delay in payment by government, and high commission from APMC are the major market constraints. To boost-up the adoption, large family size of the farmers, their dependency on farming and continuing newly selected farmers with field demonstration of location-specific low-cost technologies up to five years should be considered.
