ADOPTION OF AI-ENABLED ROBO-ADVISORS IN FINTECH: SIMULTANEOUS EMPLOYMENT OF UTAUT AND THE THEORY OF REASONED ACTION

In fintech, robo-advisors are a helpful technology for users desiring to use financial services remotely; as such, robo-advisors are being used by an increasing number of users. However, service providers of this artificial intelligence (AI)-based technology still have challenges to solve, such as issues with security, privacy, and distrust. In addition to technological benefits, we argue that if the service providers were to consider the risk-sensing behavioral attitudes of users toward AI-based robo-advisors, then more users may be attracted to this technology. By simultaneously employing the unified theory of acceptance and use of technology (UTAUT) and the theory of reasoned action (TRA), we develop a conceptual model and propose a series of hypotheses related to users’ adoption of robo-advisors in fintech services. Specifically, we argue that the antecedents (i.e., performance expectancy, effort expectancy, social influence, and facilitating conditions) affect the positive attitudes that individual investors hold toward robo-advisors, and we claim that the TRA-related factors (i.e., perceived security, perceived privacy, and trust) play vital roles in encouraging the use of robo-advisors. Using large-scale survey data from 638 Chinese users having experience with robo-advisor services, we empirically tested our framework using the structural equation modeling approach. The results clearly support the proposed hypotheses concerning the direct and indirect effects of various predictors, such as performance expectancy, effort expectancy, social influence, facilitating conditions, perceived security, and perceived privacy, on user attitudes toward robo-advisors and their intention to adopt such fintech services. In addition, our results demonstrate that the majority of these relationships are indirect by virtue of the mediating roles of attitude, trust, and facilitating conditions. This study contributes to the understanding of users’ adoption of robo-advisors by combining UTAUT and TRA, which is useful for exploring the relationships between attitudes and behavioral intentions to use as well as the interrelationships among security, privacy, and trust.
Cutting-edge issues in core-collapse supernova theory

Abstract Based on our multi-dimensional neutrino-radiation hydrodynamic simulations, we report several cutting-edge issues about the long-veiled explosion mechanism of core-collapse supernovae (CCSNe). In this contribution, we pay particular attention to whether three-dimensional (3D) hydrodynamics and/or general relativity (GR) would or would not help the onset of explosions. Our results from the first generation of full GR 3D simulations including approximate neutrino transport are quite optimistic, indicating that both of the two ingredients can foster neutrino-driven explosions. We give an outlook with a summary of the most urgent tasks to draw a robust conclusion to our findings.
News on fake news

This article presents a qualitative study of media discourses around fake news, examining 288 news articles from two national elections in Denmark in 2019. It explores how news media construct fake news as a national security threat and how journalists articulate their own role in relation to this threat. The study draws on discourse theory and the concept of logics to critically map how particular meaning ascriptions and subject positions come to dominate over others, finding five logics undergirding media discourses: (1) a logic of anticipation; (2) a logic of exteriorisation; (3) a logic of technologisation; (4) a logic of securitisation; and (5) a logic of pre-legitimation. The article concludes that fake news is constructed as an ‘ultimate other’ in Danish media discourses, potentially contributing to blind spots in both public perception and political solutions. This resonates with previous studies from other geo-political contexts, calling for further cross-national research.
Radiation belt electron acceleration during the 17 March 2015 geomagnetic storm: Observations and simulations

Various physical processes are known to cause acceleration, loss, and transport of energetic electrons in the Earth's radiation belts, but their quantitative roles in different time and space need further investigation. During the largest storm over the past decade (17 March 2015), relativistic electrons experienced fairly rapid acceleration up to ~7 MeV within 2 days after an initial substantial dropout, as observed by Van Allen Probes. In the present paper, we evaluate the relative roles of various physical processes during the recovery phase of this large storm using a 3‐D diffusion simulation. By quantitatively comparing the observed and simulated electron evolution, we found that chorus plays a critical role in accelerating electrons up to several MeV near the developing peak location and produces characteristic flat‐top pitch angle distributions. By only including radial diffusion, the simulation underestimates the observed electron acceleration, while radial diffusion plays an important role in redistributing electrons and potentially accelerates them to even higher energies. Moreover, plasmaspheric hiss is found to provide efficient pitch angle scattering losses for hundreds of keV electrons, while its scattering effect on > 1 MeV electrons is relatively slow. Although an additional loss process is required to fully explain the overestimated electron fluxes at multi‐MeV, the combined physical processes of radial diffusion and pitch angle and energy diffusion by chorus and hiss reproduce the observed electron dynamics remarkably well, suggesting that quasi‐linear diffusion theory is reasonable to evaluate radiation belt electron dynamics during this big storm.
What Are the Barriers and Facilitators for Critical Care Nurse Participation in a Patient Blood Management Program?

BACKGROUND Patient blood management (PBM) programs strive to implement best practices, mitigating blood loss through procedures to decrease anemia and the need for transfusion. Critical care nurses may have the greatest impact on blood preservation and anemia prevention for the most critically ill patients. Nurse perceptions of barriers and facilitators in PBM are not fully understood. OBJECTIVES The primary aim was to determine critical care nurses' perceptions of barriers and facilitators to participation in PBM. The secondary aim was to understand ways in which they believe the barriers can be addressed. METHODS A qualitative descriptive method was used following Colaizzi's process. Critical care nurses (n = 110) were recruited from 10 critical care units in 1 quaternary care hospital to participate in focus groups. Data were analyzed using qualitative methodology and NVivo software. Communication interactions were categorized into codes and themes. RESULTS Study findings were gathered under 5 categories: assessing need for blood transfusions, laboratory challenges, availability and appropriateness of supplies, minimizing need for laboratory draws, and communication. Three prominent themes indicated that (a) critical care nurses have a limited awareness of PBM, (b) critical nurses must be empowered to engage in interprofessional collaboration, and (c) addressing barriers is not complex. CONCLUSION The data provide insight into the challenges of critical care nurse participation in PBM, driving next step efforts in building on the institution's strengths and improving engagement. It is imperative that the recommendations derived from critical care nurses' experiences be further developed.
Evaluation of Training in Identifying and Responding to Suicide Risk by Staff of a Behavioral Health Managed Care Organization

Purpose of Study: Gatekeeper training for individuals who may be in contact with someone contemplating suicide is a recommended suicide prevention strategy. This study assessed organizational-level gatekeeper training. Primary Care Setting(s): Gatekeeper training was conducted in a behavioral health managed care organization (BHMCO), which facilitates integrated behavioral and physical health services for 1.4 million Medicaid-enrolled Pennsylvanians. Methodology and Sample: Gatekeeper training was offered to BHMCO staff via a new training policy. Gatekeeper trainers were qualified BHMCO staff. Approximately half (47%) of trained staff served as care managers. Pre- and posttraining surveys were administered to assess self-reported confidence in ability to identify and assist individuals at risk for suicide. Post-training, staff responded to a hypothetical vignette involving suicide risk, which was evaluated for skills by gatekeeper trainers. Results: Eighty-two percent of staff completed training. Mean confidence scores improved significantly from pre- (η = 615) to posttraining (η = 556) (understanding = 3.41 vs. 4.11, respectively; knowledge = 3.47 vs. 4.04; identification = 3.30 vs. 3.94; respond = 3.30 vs. 4.04, p < .0001 for each). Intermediate and advanced skills to address suicide risk were demonstrated post-training in 68.6% and 17.2% of staff, respectively. More care managers versus other BHMCO staff demonstrated advanced skills (21.6% vs. 13.0%); however, both groups showed significant improvement pre- to post-training. Implications for Case Management: Care managers benefit from suicide prevention training and are uniquely positioned to serve as organizational leaders to successful population health initiatives to decrease suicide through training and education.
Graphene growth on silicon carbide: A review

Graphene has been widely heralded over the last decade as one of the most promising nanomaterials for integrated, miniaturized applications spanning from nanoelectronics, interconnections, thermal management, sensing, to optoelectronics. Graphene grown on silicon carbide is currently the most likely candidate to fulfill this promise. As a matter of fact, the capability to synthesize high‐quality graphene over large areas using processes and substrates compatible as much as possible with the well‐established semiconductor manufacturing technologies is one crucial requirement. We review here, the enormous scientific and technological advances achieved in terms of epitaxial growth of graphene from thermal decomposition of bulk silicon carbide and the fine control of the graphene electronic properties through intercalation. Finally, we discuss perspectives on epitaxial graphene growth from silicon carbide on silicon, a particularly challenging area that could result in maximum benefit for the integration of graphene with silicon technologies.
Soil test crop response correlation studies under integrated plant nutrition system for onion (Allium cepa L. var. aggregatum) in inceptisols of Tamil Nadu

Soil test crop response correlation studies were conducted with onion (var. CO.4) under integrated plant nutrition system (STCR-IPNS) in Inceptisols of Tamil Nadu during 1998–99. Fertilizer adjustment equations under IPNS were formulated for onion following Ramamoorthy's inductive-cum-targeted yield model. The nutrient requirement for producing one quintal of fresh onion bulbs was found to be 0.375, 0.329 and 0.466 kg of N, P2O5 and K2O, respectively. The per cent contributions from soil and fertilizer nutrients were found to be 14.13 and 38.28 for N, 35.33 and 56.61 for P2O5 and 14.33 and 70.03 for K2O respectively. Likewise, the per cent contributions from farmyard manure (FYM), and FYM plus Azospirillum (Azo) were 20.32 and 22.51 for N, 16.55 and 17.12 for P2O5 and 25.17 and 25.66 for K2O respectively. The per cent contribution of N from Azospirillum was found to be 22.38. The quantity of fertilizers that could be adjusted to the levels and sources of organic manures was evaluated to be 36, 15 and 27 kg ha−1 of N, P2O5 and K2O, respectively for fertilizers with FYM; 12 kg N ha−1 for fertilizers with Azospirillum and 52, 16 and 27 kg ha−1 of N, P2O5 and K2O, respectively for fertilizers with FYM plus Azospirillum.
Exploring Many-body Physics with Ultracold Atoms

By exploiting the versatility of ultracold atoms experiments, a variety of many-body phe- nomena can be studied. Ferromagnetism in a trapped ultracold gas of repulsively interacting fermions is considered within a local-density approximation and beyond, where energetic sig- natures indicate its onset. Transport of a Bose-Einstein condensate is explored experimentally in a tunable double-well potential, and a crossover from hydrodynamic to Josephson transport is observed as the barrier between condensates is raised. To add a degree of freedom for the manipulation of ultracold gases, two schemes for species-speciﬁc optical lattices are developed theoretically.
Towards an Analytical Model for Film Cooling Prediction using Integral Turbulent Boundary layer

The objective of this work is to develop deep theoretical methods that are based on the solution of the integral boundary layer equations for investigating film cooling in liquid rocket engine. The integral model assumes that heat is transferred from hot free stream gas to the liquid film both by convection and radiation. The mass is transferred to the free srteam gas by the well-known blowing process. Downstream of the liquid film, the gas effectiveness is obtained by solving boundary layer integral equations. It incorporates a differential model for calorimeter mixing between liquid vapors in the boundary layer with the free stream gas entrained in the boundary layer. Comparisons with existing theoretical and experimental results indicate the film coating trends were well predicted by the present integral model proposed by us.
Optical response of dipole antennas on an epsilon-near-zero substrate

Materials with vanishing permittivity (epsilon-near-zero or ENZ materials) show unconventional optical behavior. Here we show that plasmonic dipole antennas on an ultrathin ENZ substrate have properties significantly different from antennas on a traditional substrate. Specifically, the presence of a 23-nm-thick ENZ material strongly modifies the linear response of plasmonic antennas and, as a result, the resonant wavelength is independent of the linear dimensions of the dipole antenna.
INFLUENCE OF VISUAL FIELD TESTING ON INTRAOCULAR PRESSURE IN PATIENTS WITH GLAUCOMA SUSPECTS ATTENDING TERTIARY CARE CENTER IN KATHMANDU

Background: The evaluation of glaucoma includes measurement of the intraocular pressure and Visual field. Both procedures frequently take place on the same appointment. A rise in intraocular pressure brought on by either internal or external sources could change the recommended course of treatment. The management of patients, therefore, benefits from understanding intraocular pressure changes and their implications. The goal of this study was to determine how visual field testing affected intraocular pressure in glaucoma suspects and glaucoma patients. Methods: The study’s cross-sectional design was carried out from October 15, 2020, to September 15, 2021, in a tertiary eye care facility. Intraocular pressure was measured before and after the visual field test. Data entry, as well as data analysis, was done on IBM SPSS 20. For comparisons of the intraocular pressure, the Wilcoxon signed-ranks test was used. A P ≤0.05 was considered statistically significant. Results: The Analysis of the data set showed no statistical significance difference between the intraocular pressures obtained before and after the test in each of the eyes and regarding the test duration Conclusions: Short-duration visual field testing did not significantly influence intraocular pressure, according to the study. This finding suggests that when clinically evaluating both the glaucoma patients and suspects, the visual field test may be done concurrently with the intraocular pressure measurement.
Connection to Place: Exploring Community Satisfaction and Attachment among Rural Youth

Abstract:Research on community satisfaction and attachment has been conducted over several decades, with most studies focused on older adult populations. The purpose of the present study was to develop and test models of community satisfaction and attachment for youth. Using a sample of youth ages 15–21 from rural eastern Germany, the proposed models examined the importance of sociodemographic, length of residence and social ties, population, and community feature variables in explaining satisfaction and attachment. Multiple regression analysis indicated the importance of length of residence and social variables, particularly for attachment, and social, housing, and leisure aspects of community life for satisfaction. The results are similar to those from adult studies. Future research is encouraged to replicate and expand upon this study. Furthermore, adult community leaders are encouraged to use the findings to develop opportunities and community features of relevance to youth.
Dupilumab for COPD with Type 2 Inflammation Indicated by Eosinophil Counts.

BACKGROUND In some patients with chronic obstructive pulmonary disease (COPD), type 2 inflammation may increase exacerbation risk and may be indicated by elevated blood eosinophil counts. Dupilumab, a fully human monoclonal antibody, blocks the shared receptor component for interleukin-4 and interleukin-13, key drivers of type 2 inflammation. METHODS In a phase 3, double-blind, randomized trial, we assigned patients with COPD who had a blood eosinophil count of at least 300 per microliter and an elevated exacerbation risk despite the use of standard triple therapy to receive dupilumab (300 mg) or placebo subcutaneously once every 2 weeks. The primary end point was the annualized rate of moderate or severe exacerbations of COPD. Key secondary and other end points that were corrected for multiplicity were the change in the prebronchodilator forced expiratory volume in 1 second (FEV1) and in the scores on the St. George's Respiratory Questionnaire (SGRQ; range, 0 to 100, with lower scores indicating a better quality of life) and the Evaluating Respiratory Symptoms in COPD (E-RS-COPD; range, 0 to 40, with lower scores indicating less severe symptoms). RESULTS A total of 939 patients underwent randomization: 468 to the dupilumab group and 471 to the placebo group. The annualized rate of moderate or severe exacerbations was 0.78 (95% confidence interval [CI], 0.64 to 0.93) with dupilumab and 1.10 (95% CI, 0.93 to 1.30) with placebo (rate ratio, 0.70; 95% CI, 0.58 to 0.86; P<0.001). The prebronchodilator FEV1 increased from baseline to week 12 by a least-squares (LS) mean of 160 ml (95% CI, 126 to 195) with dupilumab and 77 ml (95% CI, 42 to 112) with placebo (LS mean difference, 83 ml; 95% CI, 42 to 125; P<0.001), a difference that was sustained through week 52. At week 52, the SGRQ score had improved by an LS mean of -9.7 (95% CI, -11.3 to -8.1) with dupilumab and -6.4 (95% CI, -8.0 to -4.8) with placebo (LS mean difference, -3.4; 95% CI, -5.5 to -1.3; P = 0.002). The E-RS-COPD score at week 52 had improved by an LS mean of -2.7 (95% CI, -3.2 to -2.2) with dupilumab and -1.6 (95% CI, -2.1 to -1.1) with placebo (LS mean difference, -1.1; 95% CI, -1.8 to -0.4; P = 0.001). The numbers of patients with adverse events that led to discontinuation of dupilumab or placebo, serious adverse events, and adverse events that led to death were balanced in the two groups. CONCLUSIONS Among patients with COPD who had type 2 inflammation as indicated by elevated blood eosinophil counts, those who received dupilumab had fewer exacerbations, better lung function and quality of life, and less severe respiratory symptoms than those who received placebo.

Participatory variety evaluation and selection of improved onion (Allium cepa L.) varieties for bulb yield under supplementary irrigation condition at Basketo Special District, Southern Ethiopia

Onion is one of the most important vegetables and high economic crops, but grown by a few small-scale farmers in Basketo special district (woreda). Likewise, productivity of the crop in the district is very low. Lack of improved onion varieties and the use of inappropriate agronomic practices are among the major factors that limit the productivity of onions in the study area. Hence, this study was conducted at Basketo special woreda in 2019 and 2020 cropping seasons under supplementary irrigation to evaluate adaptability and to select high yielding onion varieties using farmers’ selection criteria. The experiment consisted of five improved onion varieties, namely; Adama red, Bombay red, Nafis, Adama Red, Robaf and Nasik Red and arranged in Randomized Complete Block Design in three replications. The results revealed that onion varieties exhibited differential performance in the two cropping seasons in the study area. Accordingly, Nasik red variety gave the highest bulb weight, marketable and total bulb yield (13.23 and 1.75 t/ha) and took a short period for bulb maturity compared to other onion varieties in the two cropping seasons. On the other hand, variety Bombay red produced 11.7 and 11.3 t/ha during the year. However, variety ‘Nafis’ was also selected by the farmers through their criteria. Therefore, onion varieties Nasik red (129.9Q/ha) and Nafis (106.1 Q/ha) are selected and recommended for the onion growers in the study area for better bulb yield.
Theorizing Potential Downstream Cultural Consequences of LGBT+ Activism

To what extent does local LGBT+ activism have impacts beyond its immediate surroundings? We offer a theoretical framework emphasizing how a combination of local movement visibility and LGBT+ cultural receptivity can account for disseminating influences of LGBT+ activism. We illustrate our framework in part through an analysis of the potential diffusion of LGBT+ support in Bosnia in the aftermath of the country’s first-ever Pride. Our model explains why the 2019 Sarajevo Pride increased LGBT+ support locally but had no immediate effects on attitudes in greater Bosnia. It also explains why LGBT+ support has since expanded beyond the capital to Bosnia’s surrounding regions in a follow-up 2021 study. Even when local LGBT+ visibility is low or nonexistent, underlying cultural receptivity can be conducive to the gradual diffusion of LGBT+ support. Moreover, the challenging circumstances of the pandemic did not undermine the expansion of LGBT+ tolerance across Bosnia. Our findings illustrate the persistent power as well as limitations of LGBT+ activism to usher in downstream cultural change.
Divertor plasma detachment

Regime with the plasma detached from the divertor targets (detached divertor regime) is a natural continuation of the high recycling conditions to higher density and stronger impurity radiation loss. Both the theoretical considerations and experimental data show clearly that the increase of the impurity radiation loss and volumetric plasma recombination causes the rollover of the plasma flux to the target when the density increases, which is the manifestation of detachment. Plasma-neutral friction (neutral viscosity effects), although important for the sustainment of high density/pressure plasma upstream and providing the conditions for efficient recombination and power loss, is not directly involved in the reduction of the plasma flux to the targets. The stability of detachment is also discussed.
Some projectively Ricci-ﬂat ( ˛ , ˇ ) -metrics

In this paper, we construct some projectively Ricci-ﬂat Finsler metrics deﬁned by a Riemannian metric α and a 1-form β . Moreover, we classify the projectively Ricci-ﬂat (α, β) -metrics under the condition, that β is a non-parallel Killing form which has non-zero constant length.
