Debunking and exposing misinformation among fringe communities: Testing source exposure and debunking anti-Ukrainian misinformation among German fringe communities
Authors: Santos Okholm Johannes Christiern , Ebrahimi Fard Amir , ten Thij Marijn
Published: February 2024

Through an online field experiment, we test traditional and novel counter-misinformation strategies among fringe communities. Though generally effective, traditional strategies have not been tested in fringe communities, and do not address the online infrastructure of misinformation sources supporting such consumption. Instead, we propose to activate source criticism by exposing sources’ unreliability. Based on a snowball sampling of German fringe communities on Facebook, we test if debunking and source exposure reduce groups’ consumption levels of two popular misinformation sources. Results support a proactively engaging counter-misinformation approach to reduce consumption of misinformation sources.
Efficacy of metformin and electrical pulses in breast cancer MDA-MB-231 cells
Authors: Sahu Praveen , Camarillo Ignacio G. , Sundararajan Raji
Published: February 2024

Aim: Triple-negative breast cancer (TNBC) is a very aggressive subset of breast cancer, with limited treatment options, due to the lack of three commonly targeted receptors, which merits the need for novel treatments for TNBC. Towards this need, the use of metformin (Met), the most widely used type-2 diabetes drug worldwide, was explored as a repurposed anticancer agent. Cancer being a metabolic disease, the modulation of two crucial metabolites, glucose, and reactive oxygen species (ROS), is studied in MDA-MB-231 TNBC cells, using Met in the presence of electrical pulses (EP) to enhance the drug efficacy.
Methods: MDA-MB-231, human TNBC cells were treated with Met in the presence of EP, with various concentrations Met of 1 mmol/L, 2.5 mmol/L, 5 mmol/L, and 10 mmol/L. EP of 500 V/cm, 800 V/cm, and 1,000 V/cm (with a pulse width of 100 µs at 1 s intervals) were applied to TNBC and the impact of these two treatments was studied. Various assays, including cell viability, microscopic inspection, glucose, ROS, and wound healing assay, were performed to characterize the response of the cells to the combination treatment.
Results: Combining 1,000 V/cm with 5 mmol/L Met yielded cell viability as low as 42.6% at 24 h. The glucose level was reduced by 5.60-fold and the ROS levels were increased by 9.56-fold compared to the control, leading to apoptotic cell death.
Conclusions: The results indicate the enhanced anticancer effect of Met in the presence of electric pulses. The cell growth is inhibited by suppressing glucose levels and elevated ROS. This shows a synergistic interplay between electroporation, Met, glucose, and ROS metabolic alterations. The results show promises for combinational therapy in TNBC patients.

Published: February 2024

Aim: To investigate magnetic resonance imaging (MRI)-based peritumoral texture features as prognostic indicators of survival in patients with colorectal liver metastasis (CRLM).
Methods: From 2007–2015, forty-eight patients who underwent MRI within 3 months prior to initiating treatment for CRLM were identified. Clinicobiological prognostic variables were obtained from electronic medical records. Ninety-four metastatic hepatic lesions were identified on T1-weighted post-contrast images and volumetrically segmented. A total of 112 radiomic features (shape, first-order, texture) were derived from a 10 mm region surrounding each segmented tumor. A random forest model was applied, and performance was tested by receiver operating characteristic (ROC). Kaplan-Meier analysis was utilized to generate the survival curves.
Results: Forty-eight patients (male:female = 23:25, age 55.3 years ± 18 years) were included in the study. The median lesion size was 25.73 mm (range 8.5–103.8 mm). Microsatellite instability was low in 40.4% (38/94) of tumors, with Ki-ras2 Kirsten rat sarcoma viral oncogene homolog (KRAS) mutation detected in 68 out of 94 (72%) tumors. The mean survival was 35 months ± 21 months, and local disease progression was observed in 35.5% of patients. Univariate regression analysis identified 42 texture features [8 first order, 5 gray level dependence matrix (GLDM), 5 gray level run time length matrix (GLRLM), 5 gray level size zone matrix (GLSZM), 2 neighboring gray tone difference matrix (NGTDM), and 17 gray level co-occurrence matrix (GLCM)] independently associated with metastatic disease progression (P < 0.03). The random forest model achieved an area under the curve (AUC) of 0.88.
Conclusions: MRI-based peritumoral heterogeneity features may serve as predictive biomarkers for metastatic disease progression and patient survival in CRLM.

A Proposed Controller for Pitch Angle of Wind Turbine
Authors: Mousa Norhan M. , El-Shaer Yasser I. , El-Sebah Mohamed I. Abu
Published: February 2024

Wind turbines are complicated non-linear systems with certain random disruptions. The pitch control system is a commonly employed method for regulating the electricity generated by a wind turbine. Many researchers have observed developments in the pitch control field during the last few decades. Traditional PID controllers have the drawback of being slow or imprecise when wind and pitch angles suddenly change. These drawbacks can be solved with artificial intelligent algorithms. However, the algorithms' design and implementation are highly complex. A new pitch-regulated variable-speed control strategy for wind turbines to address their nonlinear properties is presented. To manage the pitch system's control mechanisms with disturbances, this research evolved a mathematical model that illustrates HAWT's pitch angle control system and applied a proposed Simple Optimal Intelligent PID Controller (SOI-PID). Under various operating conditions, the proposed SOI-PID controller was tested with the Traditional PID, Fuzzy Logic Controller (FLC), and Fuzzy-Adaptive-PID controller. For system simulation, the MATLAB/Simulink software was used. According to simulation results, compared to PID, FLC, and Fuzzy-Adaptive-PID controllers, the proposed SOI-PID controller responds faster and has a better rise and settling time. Other benefits of the SOI-PID controller are its simplicity of implementation and design, distinguishing it from other intelligent algorithms.
“Cultivate Beauty with Beauty, Share beauty with Others” — towards Chinese Utopian Thought “Great Harmony”
Authors: Zhang Yu
Published: February 2024

Just like the “Utopia” in the West, China also has its own ideal form of the world, which is the idea of “Great Harmony”.Great Harmony is an ancient Chinese thought, which refers to the ideal world that mankind can finally reach, and represents mankind’s beautiful vision for the future society. Nowadays,with the increasing cultural exchanges, the question of “how to deal with the cultural relations among various ethnic groups in China and even the world to promote cultural diversity and cultural prosperity?” is becoming more and more urgent. A short, powerful sentence in dealing with cultural relations of Mr. Fei Xiaotong , “Every form of beauty has its uniqueness;precious is to appreciate other forms of beauty with openness;if beauty represents itself with diversity and integrity,the world will be blessed with harmony and unity” answered this question, and once again enriched the connotation of China’s “Great Harmony” thought by focusing on Beauty, create beauty, respect different beauties, and ultimately promote the realization of the “Great World of Harmony”.On the road to promote the realization of the “world unity” of culture, we must not only cultivate the beauty of China with the vision of beauty and the cultural foundation of beauty, but also respect the cultural diversity, handle the relationship between different civilizations, and promote the common prosperity of culture.

Published: February 2024

Plant lectins have garnered attention for their roles as laboratory probes and potential therapeutics. Here, we report the discovery and characterization of Cucumis melo agglutinin (CMA1), a new R-type lectin from melon. Our findings reveal CMA1’s unique glycan-binding profile, mechanistically explained by its 3D structure, augmenting our understanding of R-type lectins. We expressed CMA1 recombinantly and assessed its binding specificity using multiple glycan arrays, covering 1,046 unique sequences. This resulted in a complex binding profile, strongly preferring C2-substituted, beta-linked galactose (both GalNAc and Fuca1-2Gal), which we contrasted with the established R-type lectin Ricinus communis agglutinin 1 (RCA1). We also report binding of specific glycosaminoglycan subtypes and a general enhancement of binding by sulfation. Further validation using agglutination, thermal shift assays, and surface plasmon resonance confirmed and quantified this binding specificity in solution. Finally, we solved the high-resolution structure of the CMA1 N-terminal domain using X-ray crystallography, supporting our functional findings at the molecular level. Our study provides a comprehensive understanding of CMA1, laying the groundwork for further exploration of its biological and therapeutic potential.

Retroactivity in the law of treaties
Authors: Maryniv Ivanna , Averbakh Dmytro
Published: February 2024

Problem setting. One of the most ambiguous issues in the law of treaties is retroactivity of international treaties. The principle of non-retroactivity of legal norms is recognized both in national legal systems and in international law. This principle is codified in the Vienna Convention on the Law of Treaties, which states that a treaty, unless a different intention appears from the treaty or is otherwise established, does not have retroactive effect. The dispositive nature of this norm causes difficulties, which makes it necessary to study this issue in order to determine the prerequisites for the retroactivity of international treaties and to analyze practice in this area. Analysis of recent researches and publications. Scholars such as O.V. Pushnyak, I.I. Lukashuk, R.A. Kalamkaryan have studied this issue. However, there is the need for further study of this issue due to the dispositive nature of the provisions on the non-retroactivity of an international treaties, which gives states the right to act at their own discretion, thereby causing uncertainty in this matter. Purpose of research is to determine the grounds in the presence of which international treaty may have retroactive effect; examine the practice of international tribunals on this matter. Article`s main body. This study examines history of the principle of non-retroactivity of legal norms and its codification in the Vienna Convention on the Law of Treaties. Provisions of article 28 of forecited Convention are precisely analyzed. Meaning of the terms “act”, “fact” and “situation” is set. Three main grounds in the presence of which Attention is given to the examination of the Convention on the Prevention and Punishment of the Crime of Genocide and its retroactivity. Practice of international tribunals on this matter is examined. Conclusions and prospects for the development. According to the general rule, which is codified in the provisions of article 28 of the Vienna Convention on the Law of Treaties, treaties do not have retroactive effect. However, given the dispositive nature of this norm, issue of the retroactivity of this or that international treaty should be studied separately. For this purpose tribunal must in each case analyze in detail both the action/fact/situation to which treaty should be applied, as well as the treaty itself, in order to decide whether the retroactivity of the treaty is expressly formulated in its provisions, results from the interpretation of a treaty or emanates from the nature of the treaty
Two-phase Upward Flow-Induced Vibrations in U-bend under Different Orientations
Authors: Muhammad Sohail  , William Pao  , Huzaifa Azam  , Umair Khan
Published: February 2024

U-bends are frequently employed in industries to change the direction of fluid flow. Flow Induced Vibrations (FIV) are very prominent due to internal two-phase flow and vary with U-bend orientation. Potential possibilities of spatial orientations of a U-bend make it impractical to predict these vibrations using an experimental approach. This study investigates the two-phase flow-induced vibrations for 0°, 30°, 60° and 90° upward flow in a U-bend using CFD. In-plane and out-of-plane directional vibrational data was gathered for these four orientations of U-bend. For constant superficial velocities with void fraction of 0.5, impact of orientation on slug frequencies was observed with Fast Fourier Transformation. In-plane (x-axis) forces applied at the outlet bend significantly increase 39% compared to the corresponding forces at the inlet bend. Forces at the outlet bend along the y-axis (out-of-plane) were reduced by 26%, but the forces along the z-axis show a more moderate decrease of 7%. This study provides significant data essential to forming a correlation of two-phase flow-induced vibrations with multiple upward flow U-bend orientations.

Fault Diagnosis of Linear Guide Rails Based on SSTG Combined with CA-DenseNet
Authors: Wu Yanping , Song Juncai , Wu Xianhong , Wang Xiaoxian , Lu Siliang
Published: February 2024

Monitoring the status of linear guide rails is essential because they are important components in linear motion mechanical production. Thus, this paper proposes a new method of conducting the fault diagnosis of linear guide rails. First, synchrosqueezing transform (SST) combined with Gaussian high-pass filter, termed as SSTG, is proposed to process vibration signals of linear guide rails and obtain time-frequency images, thus helping realize fault feature visual enhancement. Next, the coordinate attention (CA) mechanism is introduced to promote the DenseNet model and obtain the CA-DenseNet deep learning framework, thus realizing accurate fault classification. Comparison experiments with other methods reveal that the proposed method has a high classification accuracy of up to 95.0%. The experimental results further demonstrate the effectiveness and robustness of the proposed method for the fault diagnosis of linear guide rails.

ABOUT FOLKLORE IN THE CREATIVE ACTIVITY OF MYKHAILO STARYTSKY AND MYKOLA LYSENKO AND ITS INFLUENCE ON THE FORMATION OF THE UKRAINIAN PROFESSIONAL MUSIC AND DRAMA THEATER
Authors: Kokhan Liudmyla , Kokhan Larysa
Published: February 2024

The article is devoted to the study of folklore activities of Ukrainian playwright, writer, poet, translator, theatrical and cultural figure, director, philanthropist, director of the first Ukrainian professional theater, the so-called “theater of luminaries”, Mykhailo Starytsky (1840–1904) and the founder of the Ukrainian national opera, composer, pianist, conductor, folklorist, public figure Mykola Lysenko (1842–1912). The main attention is paid to the analysis of the playwright’s use of descriptions of rituals, customs, traditions, folk morals of Ukrainians, as well as examples of the use of small folk genres, phraseology. It was found that for the Ukrainian community the study and preservation of folk traditions in the second half of the 19th century played an important role in the formation of national self-identification and national consciousness. The origins, features and functions of ethnography in Starytsky’s works are determined, in particular it is proved that the playwright’s use of descriptions of Christian and pre-Christian rites was primarily aimed at a true image of traditional Ukrainian society, an important component of which were ancient rituals, games, music and drama actions. It is shown how the rites of the winter and summer cycles of the folk calendar are reflected in various ways in the artist’s work, which is the most saturated with various bright rituals and customs. It is proved that the study of folk music significantly influenced the composer’s creativity. It is confirmed, that folklore in the works of Starytsky and Lysenko had a positive effect on the formation of the Ukrainian professional theater as a music and drama one.
The Weird and the Wonderful in Our Solar System: Searching for Serendipity in the Legacy Survey of Space and Time
Authors: Rogers Brian , Lintott Chris J. , Croft Steve , Schwamb Megan E. , Davenport James R. A.
Published: February 2024

We present a novel method for anomaly detection in solar system object data in preparation for the Legacy Survey of Space and Time. We train a deep autoencoder for anomaly detection and use the learned latent space to search for other interesting objects. We demonstrate the efficacy of the autoencoder approach by finding interesting examples, such as interstellar objects, and show that by using the autoencoder, further examples of interesting classes can be found. We also investigate the limits of classic unsupervised approaches to anomaly detection through the generation of synthetic anomalies and evaluate the feasibility of using a supervised learning approach. Future work should consider expanding the feature space to increase the variety of anomalies that can be uncovered during the survey using an autoencoder.

The Differential Speckle Survey Instrument (DSSI) was relocated to the Astrophysical Research Consortium 3.5 m telescope at Apache Point Observatory (APO) in early 2022. Here we present results from the first year of observations along with an updated instrument description for DSSI at APO, including a detailed description of a new internal slit mask assembly used to measure the instrument plate scale from first principles. Astrometric precision for DSSI at APO during this time was measured to be 2.06 ± 0.11 mas, with a photometric precision of 0.14 ± 0.04 mag. Results of 40 resolved binary systems are reported, including two that were previously unknown to be binaries: HIP 7535 and HIP 9603. We also present updated orbital fits for two systems: HIP 93903 and HIP 100714. Finally, we report updated or confirmed dispositions for five Kepler Objects of Interest (KOIs) that were previously explored in Colton et al., using speckle imaging to discern common proper motions pairs from line of sight companions: KOI-270, KOI-959, KOI-1613, KOI-1962, and KOI-3214AB.
Efficient Search and Detection of Faint Moving Objects in Image Data
Authors: Nguyen Tam , Woods Deborah F. , Ruprecht Jessica , Birge Jonathan
Published: February 2024

The search and detection of faint moving objects in image data can enable discoveries of small solar system bodies. To detect objects fainter than the single-frame sensitivity limit, track-before-detect methods can improve the signal-to-noise ratio of the object of interest by incoherently adding the object’s signal across multiple frames. However, traditional track-before-detect techniques can become computationally intensive over large search volumes. In this work, we present a computational approach to significantly speed up the search process by applying dynamic-programming techniques to implement the discrete X-ray transform. In this approach, image frames are processed in stages, in each of which pairs of frames are shifted and added to generate short-track segments, which are combined in later stages to form longer tracks. The algorithm speedup comes from the fact that a single short track segment can be reused multiple times for different longer tracks without the need for recomputing. Benchmark testing with simulated data shows that the method presented in this paper results in a significant reduction in runtime in comparison to a traditional track-before-detect approach. As a proof of concept, we demonstrated the applicability of the technique in performing a blind search for faint asteroids in image data collected from the Transiting Exoplanet Survey Satellite, leading to the detection of more than a thousand asteroids below the single-frame detection limit with moderate computational resources. The approach presented in this work has the potential to enable efficient discovery of previously undetected faint solar system objects across multiple orbit classes.

Magnetic reconnection and plasma turbulence are ubiquitous and key processes in the Universe. These two processes are suggested to be intrinsically related: magnetic reconnection can develop turbulence, and, in turn, turbulence can influence or excite magnetic reconnection. In this study, we report a rare and unique electron diffusion region (EDR) observed by the Magnetospheric Multiscale mission in the Earth’s magnetotail with significantly enhanced energetic particle fluxes. The EDR is in a region of strong turbulence within which the plasma density is dramatically depleted. We present three salient features. (1) Despite the turbulence, the EDR behaves nearly the same as that in 2D quasi-planar reconnection; the observations suggest that magnetic reconnection continues for several minutes. (2) The observed reconnection electric field and inferred energy transport are exceptionally large. However, the aspect ratio of the EDR (one definition of reconnection rate) is fairly typical. Instead, extraordinarily large-amplitude Hall electric fields appear to enable the strong energy transport. (3) We hypothesize that the high-energy transport rate, density depletion, and the strong particle acceleration are related to a near-runaway effect, which is due to the combination of low-plasma-density inflow (from lobes) and possible positive feedback between turbulence and reconnection. The detailed study on this EDR gives insight into the interplay between reconnection and turbulence, and the possible near-runaway effect, which may play an important role in other particle acceleration in astrophysical plasma.

Introduction: Biologic modifying agents are associated with an increased risk for infection with mycobacteria. The aim of this study is to document patients who received different biologic modifying therapies in our pediatric rheumatology department and the possibility of development of tuberculosis (TB).
Methodology: This retrospective study was conducted in Ankara City Hospital. Pediatric patients who were treated with biologic modifying agents between 2010-2020 were documented. Development of TB and the risk factors were assessed in this patient group.
Results: There were 72 patients who were treated with different biologic modifying agents. Tuberculin skin test (TST) was positive in 7 (9.7%) patients during follow up. Three patients whose TST was positive had received canakinumab, 2 received etanercept, 1 received adalimumab and 1 received anakinra. Median duration of therapy was 43.5 (16.5-168) months for these patients and the duration was longer than patients who did not develop latent tuberculosis (p = 0.04). Patients who developed latent TB under treatment were significantly older than the patients who did not (p = 0.01).
Conclusions: According to our findings, 9.7% of pediatric patients who received biologic modifying agent therapy developed latent TB. Patients who developed latent TB were older, and the duration of treatment was longer than patients who did not develop latent TB. Although not statistically significant, canakinumab, which is known as an agent less likely to cause TST conversion, was in fact the most common agent that caused TST conversion.

A 22-year-old male, with a history of recreational drug use, was admitted with a 24-hour history of sore throat, bilateral otalgia, fever, chills, sweats, and pain in the upper chest. The blood cultures were positive for Fusobacterium necrophorum. A thoracic and neck soft tissue computed tomography (CT) scan revealed an intratonsillar abscess and pulmonary septic emboli. Initial treatment with Piperacillin-tazobactam and Clindamycin was de-escalated after 5 days. The patient made a complete recovery after 22 days of antibiotic treatment.

Introduction: Among the persistent conditions affecting patients in the post-acute COVID-19 period, sarcopenia is increasingly emphasized. In this study, we aimed to determine the incidence of sarcopenia and to reveal the risk factors predicting it in hospitalized survivors of COVID-19.
Methodology: This is a retrospective cohort study conducted between December 2021 and May 2022 in the post-COVID follow-up center of a tertiary hospital in Turkey. One hundred and sixty-eight patients who were hospitalized because of COVID-19 and discharged were included in the study. The SARC-F scale was applied to determine the risk of sarcopenia in the participants. Twelve patients with a SARC-F score ≥ 4 before COVID-19 were excluded from the study. The medical records of the remaining 156 participants were reviewed, and their demographic characteristics, COVID-19 disease data, hemogram, and CRP parameters were also noted.
Results: Sarcopenia risk was detected in 17 (10.9%) patients whose median age was higher than the others. Increased risk for sarcopenia was higher in women, lack of education, use of assisted respirators at home, having a psychiatric illness, losing > 10% weight during the hospitalization, and being treated in the intensive care unit. Multiple regression analysis showed that female gender (OR: 8.04 [1.51-42.76]), having a psychiatric illness (OR: 13.23 [2.12-82.51]), and losing > 10% weight during hospitalization (OR: 18.46 [2.57-132.72]) predicted the sarcopenia risk.
Conclusions: Sarcopenia should be closely monitored in patients with cases of severe inflammatory effect, inadequate food intake, and diminished physical activity such as hospitalized survivors of COVID-19.

Introduction: Coronavirus disease 2019 (COVID-19) has infected millions of people globally. Many recent studies have suggested that the ABO blood type may contribute to COVID-19 infection immunopathogenesis. We aimed to determine the proportional distribution of COVID-19 infection among ABO blood types.
Methodology: This retrospective research was conducted in the city of Jodhpur (Rajasthan), India. The research involved 1140 COVID-19 patients, whose medical records were available in blood banks. The data was evaluated statistically using IBM SPSS 26.
Results: The proportion of blood group B among infected patients was highest (37.36%). Among all the cases, blood group A had the highest odds ratio of 1.062 (CI 95%, 0.92-1.21, p = 0.412). All versus one blood group analysis also showed that blood group A (odds ratio = 1.062 [CI 95%, 0.92-1.22] p = 0.412) was more likely to be infected with COVID-19 than the remaining blood groups. In the year 2021, blood group B had the highest risk of COVID-19 infection (odds ratio = 1.138).
Conclusions: Based on our findings, the blood groups A and B are more likely to be infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The overall average age for COVID-19 infection was lower, and the number of incidences in female patients was higher in 2021, relative to 2020. We found no evident relationship between COVID-19 vulnerabilities and blood group. A summary of the research is presented in Supplementary Figure 1.

The frog genus Odorrana is distributed across east and southeastern Asia. Based on morphological differences and molecular phylogenetics, a new species of the genus occurring from Leigong Mountain in Guizhou Province, China is described. Phylogenetic analyses based on DNA sequences of the mitochondrial 12S rRNA, 16S rRNA, and ND2 genes supported the new species as an independent lineage. The uncorrected genetic distances between the 12S rRNA, 16S rRNA, and ND2 genes between the new species and its closest congener were 5.0%, 4.9%, and 16.3%, respectively. The new species is distinguished from its congeners by a combination of the following characters: body size moderate (SVL 39.1–49.4 mm in males, 49.7 mm in female); head width larger than head length; tympanum distinctly visible; small rounded granules scattered all over dorsal body and limbs; dorsolateral folds absent; heels overlapping when thighs are positioned at right angles to the body; tibiotarsal articulation reaching the level between eye to nostril when leg stretched forward; vocal sacs absent in male and nuptial pads present on the base of finger I.

Exploring the influence of online word-of-mouth on hotel booking prices: insights from regression and ensemble-based machine learning methods
Authors: Lee Sangjae , Choeh Joon Yeon
Published: February 2024

Previous studies have extensively investigated the effects of online word-of-mouth (eWOM) factors such as volume and valence on product sales. However, studies of the effect of eWOM factors on product prices are lacking. It is necessary to examine how various eWOM factors can either explain or affect product prices. The objective of this study is to suggest explanatory and predictive analytics using a regression analysis and ensemble-based machine learning methods for eWOM factors and hotels booking prices. This study utilizes publicly available data from a hotel booking site to build a sample of eWOM factors. The final study sample was comprised of 927 hotels. The important eWOM factors found to affect hotel prices are the review depth and the review rating, which are moderated by a number of reviews to affect prices. The effect of the number of positive words is moderated by the review helpfulness to affect the price. The review depth and rating, along with the number of reviews, should be considered in the design of hotel services, as these provide the rationale for adjusting the prices of various aspects of hotel services. Furthermore, the comparison results when applying various ensemble-based machine learning methods to predict prices using eWOM factors based on a 46-fold cross-validation partition method indicated that ensemble methods (bagging and boosting) based on decision trees outperformed ensemble methods based on k-nearest neighbor methods and neural networks. This shows that bagging and boosting methods are effective ways to improve the prediction performance outcomes when using decision trees. The explanatory and predictive analytics using eWOM factors for hotel booking prices offers a better understanding in terms of how the accommodation prices of hotel services can be explained and predicted by eWOM factors.
