Effects of Scattering of Radiation on Wormholes

Significant progress in the development of observational techniques gives us the hope to directly observe cosmological wormholes. We have collected basic effects produced by the scattering of radiation on wormholes, which can be used in observations. These are the additional topological damping of cosmic rays, the generation of a diffuse background around any discrete source, the generation of an interference picture, and distortion of the cosmic microwave background (CMB) spectrum. It turns out that wormholes in the leading order mimic perfectly analogous effects of the scattering of radiation on the standard matter (dust, hot electron gas, etc.). However, in higher orders, a small difference appears, which allows for disentangling effects of wormholes and ordinary matter.
Consumers' Perception of the Cause-Related Marketing Effects of Bank’s Participation

Purpose: The main purpose of this study is to explore whether the Cause-Related Marketing effects of bank’s participation in public welfare activities will have a significant impact on consumers' purchase intentions. In this study, the consumer's perception of the marketing effect of good causes is tested by the experimental design method. Theoretical framework: The "Cause-Related Marketing", which combines business objectives with social responsibility of, has become a global trend in recent years. Design/methodology/approach: A questionnaire was distributed in front of the bank in the form of a questionnaire, and a total of 254 valid samples were obtained. After the test-taker read the DM advertising, they filled in the answer that best matches the question behind it. Findings: According to the data analysis results, we discover that there are significant differences between genders in the marketing effect or purchase intentions of the good cause. In addition, the bank's donation magnitude shows a significant positive relationship with the effects on the cause-related marketing for consumers. Research, practical and social implications: If a bank engages in public welfare activities, it will be more possible to attract consumers to have the interaction intention than the one which does not engage in public welfare activities. Originality/value: This study manipulates two independent variables of whether banks engage in public welfare activities and donation magnitude, and establish four different experimental scenarios by designing good-related marketing direct mail (DM) advertising.
Weakly nonlinear instability of a Newtonian liquid jet

A weakly nonlinear stability analysis of an axisymmetric Newtonian liquid jet is presented. The calculation is based on a small-amplitude perturbation method and performed to second order in the perturbation parameter. The obtained solution includes terms derived from a polynomial approximation of a viscous contribution containing products of Bessel functions with different arguments. The use of such an approximation is not needed in the inviscid case and the planar case, since the equations of those problems can be solved in an exact form. The developed model depends on three dimensionless parameters: the initial perturbation amplitude, the perturbation wavenumber and the liquid Ohnesorge number, the latter being the dimensionless liquid viscosity. The influence of the approximate terms was shown to be relatively small for a large range of Ohnesorge numbers so that they can be ignored. This simplification provides a jet model as simple to use as the previous ones, but taking into account the liquid viscosity and the cylindrical geometry. The jet model is used to reveal the effect of both the wavenumber and the Ohnesorge number on the formation of satellite drops, which is known as a nonlinear effect. Results are found in good agreement with direct numerical simulations and forced liquid jet experiments for wavenumbers lower than a threshold value. Satellite drop formation is retarded with increasing Ohnesorge number and wavenumber, as expected by the damping and size effects of viscosity. The threshold number corresponds to the maximum wavenumber for which satellite drop formation is predicted before jet breakup, and for which volume conservation is satisfied within a certain amount. The volume conservation criterion is imposed to ensure that the conclusions inferred by our model are safe.
Effect of Black Carbon and Alumina Nanofluid on Thermal and Dynamic Efficiency in Upward Spraying Cooling Tower

In cooling water systems, cooling towers play a critical role in removing heat from the water. Cooling water systems are commonly used in industry to dispose the waste heat. An upward spray cooling water systems was especially designed and investigated in this work. The effect of two nanofluids (Al2O3/ water, black carbon /water) on velocity and temperature distributions along reverse spray cooling tower at various concentrations (0.02, 0.08, 0.1, 0.15, and 0.2 wt.%) were investigated, beside the effect of the inlet water temperature (35 ,40, and 45 ͦ C) and water to air flow ratio (L/G) of 0.5, 0.75, and 1. The best thermal performance was found when the working solution contained 0.1 wt. % for each of Al2O3 and black carbon nanoparticles, with a maximum drop in temperature drops (i, e. range) of (16 ͦ C) and (20 ͦ C), respectively. The temperature of the tower's outlet water was decreased as the inlet working fluid increased, and the thermal efficiency declined with the increasing of the L/G by about 5%. However, the drop in the outlet temperature caused by the nanofluid is more than that of pure water at every point by about 6 ͦ C.
Computer-Assisted and Virtual Reality-Based Robotic Knee Arthroscopy: A Systematic Review

Knee arthroscopy (KA) is an outpatient procedure in high demand, with many finding it a potential beneficiary of robotic minimally invasive surgery. This literature study focuses on computer-assisted platforms used to aid KA, emphasizing intraoperative tools, computer navigation, and virtual simulations. A literature search on IEEE Xplore and PubMed was done. Findings indicate that semi-automatic KA uses various technologies to assist surgeons intraoperatively. Working tools can be patient-specific but need to be more ergonomic. Surgeons benefit from robust localization and path planning techniques of computer-assisted navigation intraoperatively. Virtual KA platforms somewhat mirror the actual procedure but need to integrate more surgical actions and procedures. Augmented virtuality enables anatomic 3D planning of the procedure, giving the surgical team adequate clarity and freedom. There is grand potential for robotic KA in the future, and future research should ensure its reliability and clinical adaptability.
Viscosity-modulated breakup and coalescence of large drops in bounded turbulence

In this work, we examine the influence of viscosity on breakup and coalescence of a swarm of large drops in a wall-bounded turbulent flow. We consider several values of surface tension and a wide range of drops to fluid viscosity ratios λ = ηd/ηc (with ηd the viscosity of the drops and ηc the viscosity of the carrier fluid), from λ = 0.01 to λ = 100, while we maintain the same density for drops and carrier fluids. Drops can coalesce and break following a complex dynamics that is primarily controlled by the interplay between turbulence fluctuations (measured by Reynolds number, Reτ ), surface tension (measured by Weber number, We), and λ. We use direct numerical simulation of turbulence coupled with a phase field method to describe the drops dynamics. We consider three different values of We (which is the inverse of the surface tension): We = 0.75, 1.5, and 3. For each value of We, we assume five values of λ: λ = 0.01, 0.1, 1, 10, and 100. We observe a consistent action of increasing λ, which, especially for the larger Weber numbers, decreases significantly the breakup rate of the drops. Qualitatively, an increase of drop viscosity decreases the breakup rate, very much like an increase of surface tension does. The mechanism by which drop viscosity acts is a modulation of turbulence fluctuations inside the drop, which reduces the work surface tension has to do to preserve drop integrity. We believe that this may give important indications in many industrial applications to control drop coalescence and fragmentation via the ratio of drop to fluid viscosity.
Effects of Tribromomethane on the Life-Table
Demography of the Freshwater Rotifer
Brachionus calyciflorus Pallas under Different
Algal Densities

Toxic effects of tribromomethane (TBM), a most used drinking water disinfection byproduct, on rotifers are unknown. we investigated the effects of TBM (0, 0.001, 15, 30, 45, 60, and 75 mg/L) on the life table demography of the freshwater rotifer, Brachionus calyciflorus, fed with three densities (1.0, 2.0, and 4.0 × 10 6 cells/mL) of Scenedesmus obliquus . It showed that the TBM exposure decreased survivorship and fecundity of the rotifer and significantly affected the developmental stages and life table demographic parameters of B. calyciflorus . Compared with the control, treatments with 30-75 mg/L TBM significantly prolonged the juvenile period of rotifer under different algal densities. Treatments with 0.001 and 15 mg/L TBM significantly decreased the net reproductive rate of rotifer under the algal density of 1.0 × 10 6 cells/mL, while increased and did not affect it under the algal density of 2.0 and 4.0 × 10 6 cells/mL, respectively. These results demonstrate that TBM is toxic to B. calyciflorus , and the increased algal density can reduce the toxic effects of TBM on rotifers. The current safety limit of TMB in natural water could affect the community structure of organisms in the aquatic system.
The Effect of Service Quality and Patient Satisfaction Toward Patient Loyalty in Special Regional Hospitals of South Sulawesi

The improvement and guarantee of hospital Service Quality in Indonesia should always be in the best interest of any hospital as regulated in Article 40 of Hospital Law No. 44 of 2009. Adequate Service Quality in a hospital would result in emotional bonds and positive experiences felt by patients and family, eventually strengthening loyalty in the long run. Thus, Service Quality is a critical aspect and indicator to achieve patient satisfaction hence behavioral intention to build loyalty towards the hospital and future visits. The aim of this study is to identify the effect of Service Quality and patient satisfaction in relation to patient loyalty in Special Regional Hospitals of South Sulawesi. This is a quantitative study with a cross-sectional model. The sample in this study were all patients who had been registered in the database, namely patients who had visited the outpatient service at Dadi Special Regional Hospital (RSKD), Siti Fatimah Regional Special Hospital for Mother and Child (RSKDIA), and Pertiwi Special Regional Hospital for Mother and Child (RSKDIA) in 2017-2019 with a total sample of 269 from the outpatient care, respectively. The inclusion criteria in this study are as follows: (1) Patients from the outpatient care. (2) Patients who had received hospital services twice. (3) Not suffering from any mental illness and sensory disturbances. (4) Patients who are willing to be respondents and consented to fill out research questionnaires. (5) The patient is conscious and is able to communicate. The results that were obtained show that Service Quality holds a significant effect on patient satisfaction. Service Quality has no significant effect on patient loyalty, while patient satisfaction has a significant effect on patient loyalty. The output of this study should be taken into consideration for hospitals to commit to improving the Service Quality in order to achieve patient satisfaction. Increased patient satisfaction in turn will develop loyalty, thereby accommodating the implementation of the hospital strategy and achieving hospital goals.
Zero Knowledge Proofs: A Survey

Zero knowledge protocols provide a way of proving that a statement is true without revealing anything other than the correctness of the claim. Zero knowledge protocols have practical applications in cryptography and are used in many applications. While some applications only exist on a specification level, a direction of research has produced real-world applications. Zero knowledge protocols, also referred to as zero knowledge proofs, are a type of protocol in which one party, called the prover, tries to convince the other party, called the verifier, that a given statement is true. Sometimes the statement is that the prover possesses a particular piece of information. This is a special case of zero knowledge protocol called a zero-knowledge proof of knowledge. Formally, a zero-knowledge proof is a type of interactive proof.
Interim analysis for continuous repeated measurements

In clinical trials, ethical and practical needs often lead to the use of interim analysis. One approach involves conducting interim analysis as repeated measurements accumulate on subjects. Standard group-sequential methods do not apply due to correlation among observations. Only very limited techniques have been available for continuous data. Five techniques are described and evaluated for the interim analysis of continuous repeated measurements in General Linear Multivariate Models and Growth Curve Models settings: 1) the interim analysis step-down (ISD) procedure, 2) the interim analysis modified step-down (IMSD) procedure, 3) the original modified step-down (OMSD) procedure, 4) the interim analysis HotellingLawley trace (IHLT), and 5) the Bonferroni strategy. The lSD, IMSD and Bonferroni strategy allow testing general linear hypotheses with pre-assigned spending probabilities, and without specifying the covariance structure. The ISD and IMSD procedures provide an exact overall type I error rate, while the Bonferroni strategy does not. The OMSD and IHLT procedures also provide an exact overall type I error rate, for a fixed spending pattern. The special demands of interim analysis for continuous repeated measurements led to examining the properties of such interim analysis procedures for an interesting range of conditions. Depending upon the conditions, the results lead to recommending the IMSD, OMSD, IHLT and Bonferroni techniques for interim analysis of continuous repeated measurements. •
CHEMICAL ABUNDANCES IN NGC 5024 (M53): A MOSTLY FIRST GENERATION GLOBULAR CLUSTER

We present the Fe, Ca, Ti, Ni, Ba, Na, and O abundances for a sample of 53 red giant branch stars in the globular cluster (GC) NGC 5024 (M53). The abundances were measured from high signal-to-noise medium resolution spectra collected with the Hydra multi-object spectrograph on the Wisconsin–Indiana–Yale–NOAO 3.5 m telescope. M53 is of interest because previous studies based on the morphology of the cluster’s horizontal branch suggested that it might be composed primarily of first generation (FG) stars and differ from the majority of other GCs with multiple populations, which have been found to be dominated by the second generation (SG) stars. Our sample has an average [Fe/H] = −2.07 with a standard deviation of 0.07 dex. This value is consistent with previously published results. The alpha-element abundances in our sample are also consistent with the trends seen in Milky Way halo stars at similar metallicities, with enhanced [Ca/Fe] and [Ti/Fe] relative to solar. We find that the Na–O anti-correlation in M53 is not as extended as other GCs with similar masses and metallicities. The ratio of SG to the total number of stars in our sample is approximately 0.27 and the SG generation is more centrally concentrated. These findings further support that M53 might be a mostly FG cluster and could give further insight into how GCs formed the light element abundance patterns we observe in them today.

Effect of Ketamine on Postoperative Neurocognitive Disorders: A Systematic Review and Meta-Analysis

Background: Neurocognitive alterations in the perioperative period might be caused by a wide variety of factors including pain, blood loss, hypotension, hypoxia, micro- and macroemboli, cardiopulmonary bypass (CPB), reperfusion damage, and surgery itself, and all are risk factors for developing postoperative delirium (POD) and postoperative cognitive dysfunction (POCD). The objective of this study was to evaluate the effect of ketamine on neurocognitive dysfunction after anesthesia. Methods: We conducted a meta-analysis of randomized controlled trials (RCTs) comparing ketamine use (experimental group) with placebo (controls). Results: The model favors the control group over the experimental group in terms of frequency of hallucinations (the risk ratio with 95% CI is 1.54 [1.09, 2.19], p-value = 0.02), the number of patients readmitted within 30 days (RR with 95% CI is 0.25 [0.09, 0.70]), and the number of adverse events (overall RR with 95% CI is 1.31 [1.06, 1.62]). In terms of morphine consumption, the model favors the experimental group. Conclusion: There was no statistically significant difference in incidences of postoperative delirium, vasopressor requirement, and fentanyl consumption between the ketamine and control groups. However, hallucinations were more frequently reported in the ketamine group.
The problems of non-coverage and unlisted numbers in telephone surveys in Britain

SUMMARY The relatively low levels of telephone ownership in Britain, particularly among certain population sub-groups, and the increasing proportion of telephone owners with unlisted ("ex-directory") numbers are two problems which militate against the use of telephone surveys in this country. This paper reviews the nature and extent of these problems and discusses a dual-mode survey approach (using telephone and face-to-face methods) which may provide a viable solution.
A Pilot Test of the Measures of the Greek Version of Upper Extremity Functional Index in Patients with Lateral Elbow Tendinopathy

Lateral elbow tendinopathy (LET) is a common upper limb pathology in people involved in manual occupations. The upper extremity functional index (UEFI) was specifically designed to evaluate functional limitations in patients with upper limb pathology. The UEFI was developed in English and has been translated into several languages, including Greek. However, it has been assessed only in patients with shoulder pathology. Thus, the aim of this study was to pilot-test the Greek version of the UEFI (GV-UEFI) questionnaire and assess its measurement properties in patients with LET. Thirty patients with LET were recruited and asked to fill in the GV-UEFI twice and the disabilities of arm, shoulder, and hand questionnaire (DASH) once. The internal consistency and test–retest reliability were examined using Cronbach’s alpha and the intraclass correlation coefficient (ICC). The standard error of measurement (SEM) and the minimum detectable change (MDC) were calculated and possible ground or ceiling effects were also examined. Convergent validity was evaluated with the Greek DASH using Pearson’s correlation. Lastly, the unidimensionality of the scale was examined through principal component analysis to verify construct validity. Internal consistency was high for the GV-UEFI (Cronbach’s a = 0.98) and test–retest reliability was excellent (ICC = 0.98). The SEM was 2.95 and the MDC was 6.85. Test–retest reliability of each item was good (ICC > 0.87). The correlation analysis demonstrated a strong correlation between the GV-UEFI and the DASH. No floor or ceiling effects were found. Principal component analysis verified the construct validity and the unidimensionality of the scale. The GV-UEFI was successfully tested in patients with LET. It seems that the GV-UEFI can be used reliably in Greek-speaking patients with LET. However, the measurement properties of this scale should be examined in a larger sample of LET patients.

Evaluation of the Expression Intensity of Glucose Transporter-1 Marker and its Diagnostic Value in Differentiating Between Borderline and Malignant Ovarian Epithelial Tumors

Background: Ovarian cancer ranks second among gynecological cancers worldwide. This study aimed to compare the glucose transporter-1 (GLUT-1) expression in benign, borderline, and malignant ovarian epithelial tumors and evaluate GLUT-1 expression as a diagnostic tool for distinguishing tumors in the ovary. Materials and Methods: This descriptive-analytical cross-sectional study analyzed 69 pathological samples of patients diagnosed with ovarian epithelial tumors who underwent oophorectomy. Immunohistochemical staining was performed using GLUT-1 antibody. The intensity of cell membrane staining and the proportion of positive neoplastic cells were graded to score immunostaining. Chi-square/Fisher’s exact test was used to analyze the data. The sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV), and staining accuracy for GLUT-1 in distinguishing borderline from invasive tumors were calculated by standard methods (P<0.05). Results: In all benign tumors, GLUT-1 staining was negative. In addition, weak staining intensity was observed in 38.5% of borderline tumors, and 96% of invasive tumors had strong staining intensity (P<0.001). Strong GLUT-1 staining was found in 94.7% of Papillary Serous Carcinoma, 9/1% of Borderline Serous tumors, 100% of Brenner tumors, and clear cell carcinoma. The results demonstrated a high diagnostic value of GLUT-1 expression intensity in differentiating between borderline and malignant ovarian epithelial tumors (Accuracy: 97.10, Sensitivity: 96%, Specificity: 97.73). Conclusion: Overall, GLUT-1 expression could help distinguish benign from borderline, especially borderline from malignant ovarian epithelial tumors. Thus, it seems that it provides useful prognostic information, particularly for the borderline category.
