Published: May 2021

The models used for analyzing and measuring quality in tourist destinations are changing with the incorporation of new techniques derived from data science and artificial intelligence. Recent studies show how social media and e-word of mouth (e-WoM) are playing key roles in the perception and image diffusion of tourist destinations. Thus, it is necessary to look for new methods for analyzing the tourist management and attractiveness of tourist spots. This includes conducting a sentiment analysis of tourists that modifies former research methods based on previously proposed model, supported by a survey, which obtained predefined and incomplete results. This study analyzed the quality of tourism in Spain, a major tourist destination that is considered to be the country with the greatest tourist competitiveness according to the World Economic Forum, and in China, the country with the greatest level of development and potential. A sentiment analysis was carried out to measure the quality of tourist destinations in Spain, and this involved three challenges: (1) the analysis of the sentiments of Chinese tourists obtained from e-WoM; (2) the use of new models to measure the quality of a destination based on information from Chinese social networks, and (3) the use of the latest artificial intelligence analytical technologies. Our findings demonstrate how sentiment analysis can be a determining factor in measuring WoM and identifying areas of development in tourist destinations in order to build a more sustainable destination. The results includes the following aspects: (1) the use of real images with more empirical evidence, (2) the use of impressive and disappointing sentiments, (3) a “no comment status”, (4) elimination of stereotypes, and (5) the identification of new opportunities and segments.

The building stock accounts for a significant portion of worldwide energy consumption and greenhouse gas emissions. While the majority of the existing building stock has poor energy performance, deep renovation efforts are stymied by a wide range of human, technological, organisational and external environment factors across the value chain. A key challenge is integrating appropriate human resources, materials, fabrication, information and automation systems and knowledge management in a proper manner to achieve the required outcomes and meet the relevant regulatory standards, while satisfying a wide range of stakeholders with differing, often conflicting, motivations. RINNO is a Horizon 2020 project that aims to deliver a set of processes that, when working together, provide a system, repository, marketplace and enabling workflow process for managing deep renovation projects from inception to implementation. This paper presents a roadmap for an open renovation platform for managing and delivering deep renovation projects for residential buildings based on seven design principles. We illustrate a preliminary stepwise framework for applying the platform across the full-lifecycle of a deep renovation project. Based on this work, RINNO will develop a new open renovation software platform that will be implemented and evaluated at four pilot sites with varying construction, regulatory, market and climate contexts.

Published: May 2021

In order to reconsider the changes of adjustment speed caused by the recapitalization cost, this research adopted dynamic capital structure theory with adjustment speed as one of the independent variables to analyze the relationship between capital structure and company performance. Instead of applying the commonly used regression models, this research used the decision tree C4.5 algorithm and association rules of priori algorithm. Taking the predictive models created by the decision tree as the main result and supporting it with association rules which help to explain the relationships between capital structure and company performance, this research shows how capital structure influences company performance. As the result presents, a company tends to have better performance when its debt ratio is low, and Tobin’s Q and ROA will turn worse as the ratio gets higher. However, maybe because of the financial leverage, ROE will not decrease when the ratio is high but will increase instead. In addition, this research found out that adjustment speed is negatively related to company performance, meaning that even though a company is more flexible in adjusting itself, it might still perform badly since it is deviating from its optimum leverage. This research found that not only capital structure, but other variables such as price-earnings ratio, research and development expense ratio, and dividend payout ratio also determine a company’s performance.
Predicting Effects of ADHD Symptoms and Mindfulness on Smartphone Overuse in Athletes: A Basic Psychological Needs Perspective
Authors: Li Chunxiao , Kee Ying Hwa , Zhang Chun-Qing , Fan Rong
Published: May 2021

Informed by basic psychological need theory, this study was undertaken to examine the relationship between self-reported symptoms of attention deficit hyperactivity disorder (ADHD), mindfulness, basic psychological need satisfaction/frustration, and smartphone overuse among athletes. Athletes (n = 360, Mage = 20.27, male = 72.5%) completed a survey that measured the outcomes of interest. Path analysis indicated that greater ADHD symptoms were both directly related to higher smartphone overuse scores and indirectly related to greater smartphone overuse scores via need frustration. Higher mindfulness scores were associated with lower levels of need frustration and greater levels of need satisfaction. Mindfulness moderated the positive association between ADHD symptoms and need frustration. Specifically, the positive association between ADHD symptoms and need frustration was attenuated in the presence of higher levels of mindfulness among participants with a lower risk of ADHD. Surprisingly, the same association was heightened among participants with a higher risk of ADHD. These findings highlight the significant role of need frustration in explaining the underlying process from ADHD symptoms to smartphone overuse.

Published: May 2021

High-performance work systems are being increasingly used in organisational management. However, such system development over time has resulted in increasingly complex impacts on employee innovation behaviour. How to stimulate innovation in the technological talent pool of individuals at high-tech enterprises has gradually become a research hotspot. Based on an effective sample of 351 technological individuals from high-tech enterprises in Jiangsu, Zhejiang and Guangdong provinces, this paper discusses the mechanism and boundary conditions of a high-performance work system affecting the active innovation behaviour of such individuals based on self-determination theory. The empirical results show the following: (1) Informational practices and controlled practices in a high-performance work system have mutually exclusive effects on active innovation behaviour, with significant positive and negative effects. (2) The need for autonomy and competence play mediating roles between informational practices and active innovation behaviour; the need for autonomy plays a masking effect between controlled practices and active innovation behaviour. (3) The need for relatedness negatively moderates the effects of a high-performance work system which is focused on the needs for autonomy and competence. The findings reveal the internal mechanism and boundary conditions of high-performance work system influencing active innovation behaviour, which provides a reference for high-tech enterprises to encourage technical talents to innovate, and have important practical significance for improving the core competitiveness of high-tech enterprises.
Research on the Two-Way Time-Varying Relationship between Foreign Direct Investment and Financial Development Based on Functional Data Analysis
Authors: Wang Deqing , Huang Qian , Ye Tianzhi , Tian Sihua
Published: May 2021

Studying how to achieve mutual promotion between financial development and foreign direct investment inflow contributes to the Chinese government’s work of formulating rational financial policy and FDI policy from a holistic point of view and promoting the healthy and ordered growth of the entire economy in China. Based on the provincial panel data from 2007 to 2018, this paper constructs comprehensive evaluation indexes for financial development and introduces functional data analysis (FDA) methods, extracts functional β-convergence from functional linear regression to analyze the two-way time-varying relationship and convergence and divergence between financial development and FDI in the country and the eastern, central, and western regions. The empirical results show that the mutual influence of FDI and financial development presents regional differences. In general, FDI has a promoting effect on financial development, while financial development has an inhibitory effect on FDI, and there is basically no convergence effect. Based on these conclusions, if the governments of various regions in China want to reduce the differences in financial development, promote coordinated financial development, and promote sustainable financial development, they should actively implement financial development policies, optimize the financial environment, and implement differentiated foreign investment policies to promote regional financial development.
Students as Change Agents for Community–University Sustainability Transition Partnerships
Authors: Budowle Rachael , Krszjzaniek Eric , Taylor Chelsea
Published: May 2021

While higher education institutions play a role in regional sustainability transitions, community–university partnerships for sustainability may be underdeveloped and fraught. Moreover, the specific role of students in building and strengthening those partnerships remains little explored. This research occurred in Laramie, Wyoming—the first community to resolve to pursue carbon neutrality in the top coal-producing state in the U.S.—amidst declining state revenue and absent any formal community–university sustainability partnership. Drawing on a community resilience framework and the social-theoretical construct of agency, we examined an informal, multi-year partnership developed through a project-based, community-engaged Campus Sustainability course at the University of Wyoming. Through a chronological sequence case study, we synthesized autoethnography, document analysis, and semi-structured interview methods involving community and university stakeholder and student participants. We found that students, rather than other university actors, played a vital bridging role in absence of a formal community–university sustainability partnership. They also served in a catalyzing role as change agents alongside community stakeholders, providing the potential to develop stronger community–university partnerships and advance sustainability transitions across other Wyoming communities. Findings suggest a need to keenly attend to power dynamics and whose agency is driving higher education institutions’ roles in regional sustainability transitions in specific contexts.
Remote Sensing-Based Dynamic Monitoring of Immovable Cultural Relics, from Environmental Factors to the Protected Cultural Site: A Case Study of the Shunji Bridge
Authors: Liu Yanzhen , Tang Yunwei , Jing Linhai , Chen Fulong , Wang Ping
Published: May 2021

This paper explores the ability of remote sensing techniques to monitor immovable cultural relics on multiple scales. The Shunji Bridge, a destroyed cultural relic, located in the Jinjiang River Basin, Fujian Province, China, was studied in terms of the environmental factors at the macroscale and the protected cultural site at the microscale. At the macroscale, moderate spatial resolution images of the Jinjiang River Basin were processed in the Google Earth Engine (GEE) platform to extract environmental factors, such as land cover and vegetation cover. At the microscale, Google Earth time series images were used to extract attribute information to reflect the spatial and temporal changes in the Shunji Bridge before, during and after its destruction. Quantitative assessment of the Shunji Bridge was performed to assess the degree of the impacts that different factors had on the immovable cultural relic. Spatial analysis methods were applied to trace back to the source of the bridge destruction and to track the situation after the bridge was destroyed. The causes of the destruction of the bridge are revealed at both the macro- and microscales. This study provides technical support for the natural disaster risk assessment of immovable cultural relics. The findings of this research can provide suggestions for the protection of immovable cultural relics.
The Thames: Arresting Ecosystem Decline and Building Back Better
Authors: Richardson Martin , Soloviev Mikhail
Published: May 2021

The Thames is an iconic river of cultural and historical importance. A cyclical process of deterioration during the last two centuries, followed by technology-driven restorations, including two major sanitation projects with a third currently underway, has produced detrimental effects on the Thames ecosystem. This paper overviews the river ecology, pollution and other anthropogenic pressures, which lead to biodiversity loss and the proliferation of non-native, pollution-tolerant species. This article further reviews past and current management, sampling and assessments trends and provides an objective overview of remediation, restoration and monitoring needs, practices and research gaps. Here, we argue that restoration work, if maladapted, can be ineffective in improving resilience or have unexpected side effects that make matters worse rather than better. We explain the need for a broader view of river restoration and management including consideration of species transplants in achieving overall sustainability against a backdrop of accelerating change in the Anthropocene.
Rheological Properties of the Jojoba Biofuel
Authors: Ghannam Mamdouh T. , Selim Mohamed Y. E.
Published: May 2021

Jojoba oil biofuel is a potential alternative to diesel fuel with attractive properties, but its flow behavior under the operating conditions of a diesel engine still needs to be clarified. In this study, the rheological properties of the jojoba biofuel are presented in assessment with diesel fuel to experimentally evaluate both their flow behaviors at different operating temperatures. A Fann-type coaxial cylinder viscometer was employed. The shear stress of the tested biofuel rises considerably with the shear rate in a marginally nonlinear manner on a logarithmic scale. Rheograms indicate that the flow behavior decreases gradually and considerably in the temperature range of 30–90 °C. The viscosity of the jojoba oil biofuel declines considerably with the decreasing applied shear rate and temperature. Based on the experimental results, a suitable model is developed for predicting the viscosity characteristics of the tested biofuel during the heating and cooling cycles of a diesel engine.

Published: May 2021

Numerical models for the flow of blood and other fluids can be used to design and optimize microfluidic devices computationally and thus to save time and resources needed for production, testing, and redesigning of the physical microfluidic devices. Like biological experiments, computer simulations have their limitations. Data from both the biological and the computational experiments can be processed by machine learning methods to obtain new insights which then can be used for the optimization of the microfluidic devices and also for diagnostic purposes. In this work, we propose a method for identifying red blood cells in flow by their stiffness based on their movement data processed by neural networks. We describe the performed classification experiments and evaluate their accuracy in various modifications of the neural network model. We outline other uses of the model for processing data from video recordings of blood flow. The proposed model and neural network methodology classify healthy and more rigid (diseased) red blood cells with the accuracy of about 99.5% depending on the selected dataset that represents the flow of a suspension of blood cells of various levels of stiffness.
An Introduction to κ-Deformed Symmetries, Phase Spaces and Field Theory
Authors: Arzano Michele , Kowalski-Glikman Jerzy
Published: May 2021

In this review, we give a basic introduction to the κ-deformed relativistic phase space and free quantum fields. After a review of the κ-Poincaré algebra, we illustrate the construction of the κ-deformed phase space of a classical relativistic particle using the tools of Lie bi-algebras and Poisson–Lie groups. We then discuss how to construct a free scalar field theory on the non-commutative κ-Minkowski space associated to the κ-Poincaré and illustrate how the group valued nature of momenta affects the field propagation.
Dynamics of a COVID-19 Model with a Nonlinear Incidence Rate, Quarantine, Media Effects, and Number of Hospital Beds
Authors: Ajbar Abdelhamid , Alqahtani Rubayyi T. , Boumaza Mourad
Published: May 2021

In many countries the COVID-19 pandemic seems to witness second and third waves with dire consequences on human lives and economies. Given this situation the modeling of the transmission of the disease is still the subject of research with the ultimate goal of understanding the dynamics of the disease and assessing the efficacy of different mitigation strategies undertaken by the affected countries. We propose a mathematical model for COVID-19 transmission. The model is structured upon five classes: an individual can be susceptible, exposed, infectious, quarantined or removed. The model is based on a nonlinear incidence rate, takes into account the influence of media on public behavior, and assumes the recovery rate to be dependent on the hospital-beds to population ratio. A detailed analysis of the proposed model is carried out, including the existence and uniqueness of solutions, stability analysis of the disease-free equilibrium (symmetry) and sensitivity analysis. We found that if the basic reproduction number is less than unity the system can exhibit Hopf and backward bifurcations for some range of parameters. Numerical simulations using parameter values fitted to Saudi Arabia are carried out to support the theoretical proofs and to analyze the effects of hospital-beds to population ratio, quarantine, and media effects on the predicted nonlinear behavior.
New Geometric Constants in Banach Spaces Related to the Inscribed Equilateral Triangles of Unit Balls
Authors: Fu Yuankang , Liu Qi , Li Yongjin
Published: May 2021

Geometric constant is one of the important tools to study geometric properties of Banach spaces. In this paper, we will introduce two new geometric constants JL(X) and YJ(X) in Banach spaces, which are symmetric and related to the side lengths of inscribed equilateral triangles of unit balls. The upper and lower bounds of JL(X) and YJ(X) as well as the values of JL(X) and YJ(X) for Hilbert spaces and some common Banach spaces will be calculated. In addition, some inequalities for JL(X), YJ(X) and some significant geometric constants will be presented. Furthermore, the sufficient conditions for uniformly non-square and normal structure, and the necessary conditions for uniformly non-square and uniformly convex will be established.

Published: May 2021

It is now recognized that additional exposure to mycotoxins may occur through inhalation of contaminated dust at a workplace. The aim of this study was to characterize the multi-mycotoxin exposure of French grain elevator workers using biomonitoring and airborne measurements. Eighteen workers participated in the study. Personal airborne dust samples were analyzed for their mycotoxin concentrations. Workers provided multiple urine samples including pre-shift, post-shift and first morning urine samples or 24 h urine samples. Mycotoxin urinary biomarkers (aflatoxin B1, aflatoxin M1, ochratoxin A, ochratoxin α, deoxynivalenol, zearalenone, α-zearalenol, β-zearalenol, fumonisin B1, HT-2 toxin and T-2 toxin) were measured using a liquid chromatography–high-resolution mass spectrometry method. Grain elevator workers were highly exposed to organic airborne dust (median 4.92 mg.m−3). DON, ZEN and FB1 were frequent contaminants in 54, 76 and 72% of air samples, respectively. The mycotoxin biomarkers quantified were DON (98%), ZEN (99%), α-ZEL (52%), β-ZEL (33%), OTA (76%), T-2 (4%) and HT-2 (4%). DON elimination profiles showed highest concentrations in samples collected after the end of the work shift and the urinary DON concentrations were significantly higher in post-shift than in pre-shift-samples (9.9 and 22.1 µg/L, respectively). ZEN and its metabolites concentrations did not vary according to the sampling time. However, the levels of α-/β-ZEL were consistent with an additional occupational exposure. These data provide valuable information on grain worker exposure to mycotoxins. They also highlight the usefulness of multi-mycotoxin methods in assessing external and internal exposures, which shed light on the extent and pathways of exposure occurring in occupational settings.

Published: May 2021

Due to the current, rapidly increasing Coronavirus disease 2019 (COVID-19) pandemic, efficient and highly specific diagnostic methods are needed. The receptor-binding part of the spike (S) protein, S1, has been suggested to be highly virus-specific; it does not cross-react with antibodies against other coronaviruses. Three recombinant partial S proteins of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) expressed in mammalian or baculovirus-insect cells were evaluated as antigens in a Luminex-based suspension immunoassay (SIA). The best performing antigen (S1; amino acids 16-685) was selected and further evaluated by serum samples from 76 Swedish patients or convalescents with COVID-19 (previously PCR and/or serologically confirmed), 200 pre-COVID-19 individuals (180 blood donors and 20 infants), and 10 patients with acute Epstein-Barr virus infection. All 76 positive samples showed detectable antibodies to S1, while none of the 210 negative controls gave a false positive antibody reaction. We further compared the COVID-19 SIA with a commercially available enzyme immunoassay and a previously evaluated COVID-19 rapid antibody test. The results revealed an overall assay sensitivity of 100%, a specificity of 100% for both IgM and IgG, a quantitative ability at concentrations up to 25 BAU/mL, and a better performance as compared to the commercial assays, suggesting the COVID-19 SIA as a most valuable tool for efficient laboratory-based serology.

Laboratory cultivation of viruses is critical for determining requirements for viral replication, developing detection methods, identifying drug targets, and developing antivirals. Several viruses have a history of recalcitrance towards robust replication in laboratory cell lines, including human noroviruses and hepatitis B and C viruses. These viruses have tropism for tissue components of the enterohepatic circulation system: the intestine and liver, respectively. The purpose of this review is to discuss how key enterohepatic signaling molecules, bile acids (BAs), and BA receptors are involved in the replication of these viruses and how manipulation of these factors was useful in the development and/or optimization of culture systems for these viruses. BAs have replication-promoting activities through several key mechanisms: (1) affecting cellular uptake, membrane lipid composition, and endocytic acidification; (2) directly interacting with viral capsids to influence binding to cells; and (3) modulating the innate immune response. Additionally, expression of the Na+-taurocholate cotransporting polypeptide BA receptor in continuous liver cell lines is critical for hepatitis B virus entry and robust replication in laboratory culture. Viruses are capable of hijacking normal cellular functions, and understanding the role of BAs and BA receptors, components of the enterohepatic system, is valuable for expanding our knowledge on the mechanisms of norovirus and hepatitis B and C virus replication.
Managing Stormwater by Accident: A Conceptual Study
Authors: Maas Carly M. , Anderson William P. , Cockerill Kristan
Published: May 2021

Stormwater-driven road salt is a chronic and acute issue for streams in cold, urban environments. One promising approach for reducing the impact of road salt contamination in streams and adjacent aquifers is to allow “accidental wetlands” to flourish in urban areas. These wetlands form naturally as a byproduct of human activities. In this study, we quantified the ability of an accidental wetland in northwestern North Carolina, USA, to reduce the timing and peak concentration of road salt in a stream. Monitoring suggests that flow and transport processes through the wetland reduce peak concentrations and delay their arrival at the adjacent stream. We expand these findings with numerical simulations that model multiple meltwater and summer storm event scenarios. The model output demonstrates that small accidental wetland systems can reduce peak salinities by 94% and delay the arrival of saltwater pulses by 45 days. Our findings indicate that accidental wetlands improve stream water quality and they may also reduce peak temperatures during temperature surges in urban streams. Furthermore, because they find their own niche, accidental wetlands may be more effective than some intentionally constructed wetlands, and provide opportunities to explore managing stormwater by letting nature take its course.

Published: May 2021

This study examined differences in the adsorption kinetics, isotherms, and thermodynamics of the dyes (methyl orange and fast green FCF) by pristine (M–biochar) and chemical activated mandarin peel biochars (MN–biochar and MZ–biochar). The specific surface area (1085.0 m2/g) and pore volume (0.194 cm3/g) of MZ-biochar much higher than those of the M–biochar (specific surface area = 8.5 m2/g, pore volume = 0.016 cm3/g) and MN–biochar (specific surface area = 181.1 m2/g, pore volume = 0.031 cm3/g). The equilibrium adsorption capacities (mg/g) of MO and FG using M–biochar (MO = 0.95, FG = 0.78) MN–biochar (MO = 2.52, FG = 2.13), and MZ–biochar (MO = 16.27, FG = 12.44) have well-matched the pseudo-second-order model (R2 ≥ 0.952) compared with the pseudo-first-order model (R2 ≥ 0.008). Furthermore, the better explanation of the adsorption behavior of dyes by the Freundlich isotherm model (R2 ≥ 0.978) than the Langmuir isotherm model (R2 ≥ 0.881) supports the assumption that the multilayer adsorption governed the adsorption of dyes using mandarin peel biochars. The adsorptions of dyes were significantly dependent on the solution pH and temperature since the electrostatic and spontaneous endothermic reactions governed their removal using the pristine and chemical activated mandarin peel biochars.

Objectives

To explore the anxiety, depression, stress and related factors in the primary caregivers of inpatients with cancer.

Methods

A total of 235 selected caregivers of inpatients with cancer were included as the research subjects, and the Depression-Anxiety-Stress Self-Rating Scale 21 (DASS-21) was used to evaluate their depression, anxiety and stress. The data were statistically analyzed using SPSS 25.0 software.

Results

The study showed that the caregivers of cancer patients had different levels of depression, anxiety and stress, but all rates were above the normal range, with 51.7%, 56.0% and 34.9% of subjects respectively reporting these conditions. In addition, the above indicators were correlated with the caregivers’ gender, age, relationship with the cancer patients, the family’s economic status, religious belief and duration of caregiving: being female (T-Statistic = -2.061, P = 0.040) and having a low income (F = 2.627, P = 0.035) were positively correlated with the caregivers’ stress level. Having a low income (F = 2.804, P = 0.027) was also positively correlated with the depression scores. When the caregivers were the patient’s parents, they had higher levels of anxiety (F = 2.429, P = 0.036) than caregivers in other relationships. The results of a linear correlation analysis showed that the depression of caregivers was negatively correlated with the family’s economic status (r value = -0.244, P < 0.01) and positively correlated with the duration of caregiving (r = 0.138, P < 0.05). The anxiety score was positively correlated with the caregivers’ age (r = 0.141, P < 0.05) and duration of caregiving (R = 0.132, P < 0.05), but negatively correlated with the family’s economic status (r = -0.187, P < 0.01). The stress level was positively correlated with the caregivers’ gender (r = 0.137, P < 0.05), age (r = 0.210, P < 0.01), duration of caregiving (r = 0.171, P < 0.01) and current job status (r = 0.165, P < 0.05), but negatively correlated with the family’s economic status (r = -0.202, P < 0.01). The results of a multiple stepwise regression showed that age and religious belief were significant predictors of stress, while the family’s economic status was a significant predictor of depression, and age was a significant predictor of anxiety.

Conclusion

The caregivers of hospitalized cancer patients showed varying degrees of anxiety, depression and stress, according the psychological assessments; the provision or interventions might be helpful for these individuals.

Participants’ sociodemographic characteristics; income level; school performance; participation in social activities; willingly choosing the registered department were also asked as well as their anthropometric measurements. Mediterranean diet adaptation scale was used to determine Mediterranean diet adherence scores. Beck Depression Scale and Profile of Mood States were used to determine the mood states of the individuals. As a result of our study, the majority of the participants were found compatible with the Mediterranean diet (75.8%) and at normal depression status (59.6%). A significant relationship was found between adherence to the Mediterranean diet and emotional states of tense, angry, energetic, fatigued (p<0.05). No significant relationship was found between the Mediterranean diet scores and the Beck depression scores (p>0.05). The relationship between Mediterranean diet and depression should be examined in more detail and individuals' awareness for the relationship between mood and nutrition should be increased.

From Ptolemy to Copernicus: a new proposal for the care of diabetes
Authors: Ponziani, M.C.
Published: May 2021

The therapeutic approach to diabetes has deeply changed in recent years due to the increasing availability of new drugs and the publication of a large number of randomized trials and real life studies focused on cardiovascular and renal safety of these drugs. The therapeutic choice following metformin is particularly complex. The most recent guidelines provide the clinician with indications related to efficacy and safety (effects on weight, hypoglycemic risk, effects on cardiovascular risk factors) directing the therapeutic choice above all in the cardiopathic patient. In this brief review is proposed a different attempt to personalize the therapy after metformin, subordinating the choice to the patient’s pathological history. KEY WORDS personalized therapy; efficacy; safety; randomized clinical trials; real word data.
