Digital Evaluation of Trueness and Fitting Accuracy of Co-Cr Crown Copings Fabricated by Different Manufacturing Technologies

Introduction: The dentistry industry has seen a number of exciting new advancements in recent years, many of which have been made possible by the introduction of automated technologies such as computer-aided design and computer-aided manufacturing (CAD/CAM). Despite the fact that these new approaches simplify the fabrication process in favor of decreased material consumption and improved time efficiency, it is possible that they may have an effect on the prosthesis’s fitness, which in turn may affect how long they will last. Purpose: The purpose of this in vitro study was to evaluate the trueness and fitness of cobalt-chromium (Co-Cr) crown copings fabricated by selective laser melting (SLM), milling, and conventional casting methods. Materials and Methods: A zirconium die was fabricated and scanned with a laboratory scanner to manufacture the Co-Cr metal copings for three groups (n = 12). In group A, the copings were fabricated by a 3D printing technique called SLM; in group B, the copings were fabricated by the milling technique; and in group C, the copings were fabricated by the conventional lost-wax method. After fabrication, the trueness and the internal fitness of the copings were evaluated using a metrology software program (Geomagic Control X, 3D Systems Inc., Rock Hill, SC). The one-way ANOVA and Tukey’s honestly significant difference test were used to statistically analyze the data. Results: The highest root mean square (RMS) value of trueness was for CAD/CAM milling, and the highest mean of horizontal gaps was for the casted (lost-wax technique) group. There were highly significant differences in the mean RMS value of trueness and the mean horizontal gaps between the three groups. Conclusion: The fabrication method of Co-Cr crown copings has an effect on the trueness and fitness of the copings.

Background and Purpose: Conventional treatment of postoperative pain with routine analgesics during orthopaedic surgery leads to undesirable side effects, especially in the elderly. Therefore, this study was designed to evaluate the efficacy of compartment block of the fascia iliaca in postoperative analgesia with ropivacaine. Methods: We performed compartment block of the fascia iliaca with 30 ml of 0.5% ropivacaine in 20 patients undergoing lower limb orthopaedic surgery under general anaesthesia. Results: Verbal pain score (VPS) decreased significantly 1 hour after blockade, and the mean duration of analgesia was 4.85±2.86 hours. Conclusion: Compartmental block of the iliac fascia is a very useful method for postoperative analgesia in orthopaedic procedures of the lower limbs.
Identification and Characterization of Diplodia parva and Diplodia crataegicola Causing Black Rot of Chinese Quince

Fungal isolates from infected Chinese quince trees were found to cause black rot in Yeongcheon, Gyeongsangbuk Province, Korea. The quince leaves withered and turned reddish-brown and fruits underwent black mummification. To elucidate the cause of these symptoms, the pathogen was isolated from infected leaf and fruit tissues on potato dextrose agar and Levan media. Several fungal colonies forming a fluffy white or dark gray mycelium and two types of fungi forming an aerial white mycelium, growing widely at the edges, were isolated. Microscopic observations, investigation of fungal growth characteristics on various media, and molecular identification using an internal transcribed spacer, β-tubulin, and translation elongation factor 1-α genes were performed. The fungal pathogens were identified as Diplodia parva and Diplodia crataegicola. Pathogenicity tests revealed that the pathogen-inoculated fruits exhibited a layered pattern, turning brown rotting; leaves showed circular brown necrotic lesions. The developed symptoms were similar to those observed in the field. Fungal pathogens were reisolated to fulfill Koch’s postulates. Apples were inoculated with fungal pathogens to investigate the host range. Strong pathogenicity was evident in the fruits, with browning and rotting symptoms 3 days after inoculation. To determine pathogen control, a fungicidal sensitivity test was conducted using four registered fungicides. Thiophanate-methyl, propineb, and tebuconazole inhibited the mycelial growth of pathogens. To the best of our knowledge, this is the first report on the isolation and identification of the fungal pathogens D. parva and D. crataegicola from infected fruits and leaves of Chinese quince, causing black rot disease in Korea.
Assessing the Internal Critical Success Factors of Service Quality in Boatels: A Case Study of Egypt

Critical success factors (CSFs) are inputs that, directly or indirectly, can contribute to a project's success. CSFs contain a variety of components, traits, requirements, or characteristics that, if properly upheld, can have a significant impact on the project's performance. Primarily internal and exterior CSFs can be easily recognized. Each of these factors cost a lot of investment whether it is internal or external. Finding essential internal success variables that have an impact on service quality for better use of investment is the aim of this study. Holistically, this study aims to examine the key success internal factors and their impact on providing high-quality service in Cruises. Internal CSFs include six variables. i.e., Senior Management Experiences, Human Resources Management (HRM), Customer focus Service culture, Management Information System (MIS), and Social Responsibility. A scale for each of these variables was used. Two hundred sixty-four returned forms were analyzed using Structural equation modeling (SEM) was used to test the measurement model of service quality internal critical success factors using AMOS 4. Keywords: internal CSFs, CSF elements, service quality (SQ), cruise
Biochar Addition with Water and Fertilization Reduction Increases Soil Aggregate Stability of 0–60 cm Soil Layer on Greenhouse Eggplant in Mollisols

Biochar application affects the soil organic carbon (SOC) content and distribution, which is relevant to facility agriculture and soil aggregates. However, how the fertilization management of facility agriculture affects the SOC content and aggregate stability at different soil depths in Mollisols is unclear. Intended to provide a basis for developing a reasonable fertilizer amount when adding biochar, the facility vegetable eggplant in Northeast China was used to explore the effects of biochar addition on the distribution and SOC content of whole soils and the organic carbon (OC) content of aggregates of each size in the profile (0–100 cm) of Mollisols. Three treatments were set up: WF (conventional application amounts of water and fertilizer), WFB (conventional application amounts of water and fertilizer and added biochar), and 80%W80%FB (20% water reduction and 20% fertilizer reduction and added biochar). The results demonstrated that the 80%W80%FB treatment significantly increased the SOC content by 56.1% and 34.0% in whole soils at a 0–20 cm soil depth compared to WF and WFB treatments, respectively. Simultaneously, compared with WF and WFB treatments, the significant increase in the OC content of 1–0.25 mm sized aggregates of 81.4–130.2% and 4.3–10.1% and the enhanced proportion of >2 mm sized aggregates of 0.22–16.15- and 0.33–0.83-fold both improved aggregate stability in the 0–20 cm soil layer under the 80%W80%FB treatment, which was proven to result in 32.6% and 30.6% increments in the weight diameter (MWD) value. Therefore, biochar addition with water and fertilizer reductions increases surface soil aggregate stability for greenhouse eggplants in Mollisols.
Description Versus Experience for Decisions About Discounts

The description–experience gap in risky choice behavior is the finding that people tend to overweight rare events when making description-based decisions, whereas they tend to underweight rare events when making experience-based decisions. In the present study, the authors investigated whether the gap, which is studied mainly in the context of monetary gambles, generalizes to the context of retail discounts in the consumer domain. In 3 experiments, subjects made description- or experience-based decisions about safe and risky discounts (scratch-and-save promotions). When discounts were expressed as percentages without a reference point, there was no evidence of a gap (Experiment 1). When discounts were expressed in dollars with an explicit reference point, there was evidence of a partial gap, such that experience subjects chose the risky promotion more often than description subjects did but only when the large discount occurred with high probability (Experiments 2 and 3). In all experiments, experience subjects tended to be more rational than description subjects when choosing between promotions with different expected values. Possible reasons for the pattern of results are discussed.
Patient Safety Culture Perception Among Surgical Nurses

Background: Human and technology factors in healthcare can lead to errors that threaten human life. A strong patient safety culture in hospitals may be linked to better patient outcomes. Because of the potential for mistakes in surgical departments, surgical nurses are critical to establishing and maintaining a patient safety culture. Aim: The aim of this study was to explore the patient safety culture perceptions of surgical nurses. Methods: This descriptive study was performed with 206 nurses working in the surgical clinics and operating rooms of 1 university hospital, 2 public hospitals, and 1 private hospital. A “Questionnaire” and the “Hospital Survey on Patient Safety Culture” were used for data collection. The data were analyzed using mean, number, and percentage values, 1-way analysis of variance, Tukey Honestly Significant Difference (HSD), and chi-square tests. Results: The study revealed that surgical nurses’ patient safety culture perception was at a medium level. The highest mean rate of positive responses in The Hospital Survey on Patient Safety Culture came from “Teamwork within units” and the lowest mean rate of positive answers came from the “Non-punitive response to errors” subdimension. In addition, 85.7% of the surgical nurses did not report any errors in the previous 1 year, and nurses who had been working for ≥ 11 years submitted more error reports ( P = .001). Conclusion: Nurses’ patient safety culture perception was at a medium level. Recommendations for improving patient safety culture should include on-the-job training programs and improvements in employees’ working conditions.
Oscillation of Second-order Nonlinear Delay Dynamic Equations on Time Scales

By using the generalized Riccati transformation and the inequality technique,we establish a new oscillation criterion for the second-order nonlinear delay dynamic equations on time scales.The results not only extend and improve some known theorems,but also unify the oscillation of the second-order nonlinear delay differential equation and the second-order nonlinear delay difference equation.
Ambiguity in Cooperative Signaling

In game-theoretic signaling models, evolution tends to favor perfectly precise signaling systems, but in the natural world communication is almost always imprecise. I argue that standard explanations for this discrepancy are only partially sufficient, and I show that communication is often ambiguous because signal senders take advantage of context sensitivity. As evidence, I make two additions to the signaling model: a cost for more complex signaling strategies and the ability to combine information in signals with independent information. Analysis and simulation of the altered model shows that it leads to the predicted outcome of evolution favoring ambiguous signaling.
Trans-rectal ultrasound-guided hybrid intra-cavitary and interstitial brachytherapy in carcinoma cervix: A feasibility study from a tertiary cancer center in India

Purpose To report the feasibility of performing hybrid intra-cavitary and interstitial (IC/IS) brachytherapy in patients with carcinoma cervix under trans-rectal ultrasound (TRUS) guidance. Material and methods All patients who received an external beam radiotherapy (EBRT) dose of 50 Gy in 25 fractions with weekly chemotherapy, followed by a brachytherapy boost (21 Gy in 3 fractions) were prospectively included for analysis. IC/IS brachytherapy was performed using Fletcher style tandem and ovoid applicator with interstitial component under TRUS guidance. Parameters of implant quality analyzed included ability to insert tandem, ratio of needles loaded to the number of needles inserted, and incidence of uterine or organ at risk (OARs) perforation. Dosimetric parameters evaluated were dose to point A*, TRAK, D90 high-risk clinical target volume (HR-CTV), and D2cc to OARs (bladder, rectum, and sigmoid). Width and thickness of the target was compared between TRUS (TRUSw and TRUSt) and MRI (MRIw and MRIt). Results Twenty carcinoma cervix patients treated with IC/IS brachytherapy were included for analysis. The mean HR-CTV volume was 36 cc. The median number of needles used were 6 (range, 2-10 needles). None of the patients had uterine perforation. Two patients had bowel and bladder perforation. The mean D90 HR-CTV and D98 HR-CTV were 87.3 Gy and 82 Gy EQD2, respectively. The mean D2cc to the bladder, rectum, and sigmoid were 80 Gy, 70 Gy, and 64 Gy EQD2, respectively. The mean dose to point A* was 70.4 Gy EQD2. The mean TRAK was 0.40. The mean TRUSw (±SD) and MRIw (±SD) were 4.58 cm (±0.44) and 4.49 cm (±0.50), respectively. The mean TRUSt (±SD) and MRIt (±SD) were 2.7 cm (±0.59) and 2.62 cm (±0.59), respectively. On statistical analysis, there was a significant correlation between TRUSw and MRIw (r = 0.93), and TRUSt and MRIt (r = 0.98). Conclusions TRUS-guided IC/IS brachytherapy is feasible and provides adequate coverage of the target, with acceptable doses to OARs.
The Non-Invasive Diagnosis of Chronic Coronary Syndrome: A Focus on Stress Computed Tomography Perfusion and Stress Cardiac Magnetic Resonance

Coronary artery disease is still a major cause of death and morbidity worldwide. In the setting of chronic coronary disease, demonstration of inducible ischemia is mandatory to address treatment. Consequently, scientific and technological efforts were made in response to the request for non-invasive diagnostic tools with better sensitivity and specificity. To date, clinicians have at their disposal a wide range of stress-imaging techniques. Among others, stress cardiac magnetic resonance (S-CMR) and computed tomography perfusion (CTP) techniques both demonstrated their diagnostic efficacy and prognostic value in clinical trials when compared to other non-invasive ischemia-assessing techniques and invasive fractional flow reserve measurement techniques. Standardized protocols for both S-CMR and CTP usually imply the administration of vasodilator agents to induce hyperemia and contrast agents to depict perfusion defects. However, both methods have their own limitations, meaning that optimizing their performance still requires a patient-tailored approach. This review focuses on the characteristics, drawbacks, and future perspectives of these two techniques.
A Transformation Factor for Superluminal Motion That Preserves Symmetrically the Spacetime Intervals

While superluminal phenomena are not empirically substantiated, they present an intriguing hypothetical case. For this speculative framework, the Lorentz transformations would necessitate a revision: instead of the standard γ(x−vt), the absolute value of x′ ought to be expressed as γ(vt−x), because if v were to exceed c, then the interval vt traversed by the superluminal frame S′ would surpass the distance covered by light. Under the postulates of relativity, the subluminal scenario leads to the conventional Lorentz factor. Meanwhile, the superluminal scenario introduces an alternative transformation factor that accounts for the presence of the speed of light (c) barrier. This factor is also invariant within Minkowski spacetime, meaning it symmetrically preserves spacetime intervals. The details of this derivation become more evident when using a reverse coordinate system. This result is not, per se, evidence for the existence of superluminal phenomena, but it does allow us to speculate with a new argument about the possibility of their existence.
Multilevel Analysis of Factors that Determine the Science Achievement of Fourth-grade Students in TIMSS 2019

This study examined the factors that determined the science achievement of fourth-grade students on the Trends in International Mathematics and Science Study (TIMSS) 2019 in the USA. The data were retrieved from the TIMSS international database and imported to the R program for manipulation. The EdSurvey package was used to conduct multilevel analysis, taking plausible values of outcome variables, and weighting into account. Level 1 predictors included gender, sense of school belonging, no student bullying, instructional clarity, and attitude toward science. Level 2 predictors included instruction being affected by science resource shortages, school emphasis on academic success, a lack of school discipline problems, and students’ preexisting with literacy and numeracy skills. The findings include that the variance between schools equals 33% and boys outperformed girls in science. Students’ attitudes toward science, their confidence, and the school’s emphasis on academic success were the two strongest positive predictors of both individual student’s achievement and the school’s mean science achievement. The other predictive variables were found to have only trivially positive or no effect. The utilized models could explain the variance within and between schools by 6% and 39%, respectively. The implications for policymakers and educational practitioners include boosting up confidence in learning science and by actively engaging students in inquiry-based activities and providing instant and constructive feedback, encouraging, and treating all students regardless of gender identity equally in teaching and learning science and schools should emphasize academic success.
Focused Ultrasound-Mediated Blood–Brain Barrier Opening Best Promotes Neuroimmunomodulation through Brain Macrophage Redistribution

Neuroimmunomodulation is a promising form of drug-free treatment for neurological diseases ranging from Alzheimer’s disease to depression. The evidence supporting the efficacy of focused ultrasound (FUS) neuroimmunomodulation is encouraging; however, the method has yet to be standardized, and its mechanism remains poorly understood. Methods of FUS neuroimmunomodulation can be categorized into three paradigms based on the parameters used. In the first paradigm, focused ultrasound blood–brain barrier opening (FUS-BBBO) combines FUS with microbubbles (MB) to transiently and safely induce BBB opening. In the second paradigm, focused ultrasound neuromodulation (FUS-N) harnesses the acoustic effects of FUS alone (without MB). In the third paradigm, focused ultrasound with microbubbles without BBBO (FUS + MB) combines MB with FUS below the BBBO pressure threshold—harnessing the mechanical effects of FUS without opening the barrier. Due to the recent evidence of brain macrophage modulation in response to FUS-BBBO, we provide the first direct comparison of brain macrophage modulation between all three paradigms both in the presence and absence of Alzheimer’s disease (AD) pathology. Flow cytometry and single-cell sequencing are employed to identify FUS-BBBO as the FUS paradigm, which maximizes brain macrophage modulation, including an increase in the population of neuroprotective, disease-associated microglia and direct correlation between treatment cavitation dose and brain macrophage phagocytosis. Next, we combine spatial and single-cell transcriptomics with immunohistochemical validation to provide the first characterization of brain macrophage distribution in response to FUS-BBBO. Given their relevance within neurodegeneration and perturbation response, we emphasize the analysis of three brain macrophage populations—disease- and interferon-associated microglia and central-nervous-system-associated macrophages. We find and validate the redistribution of each population with an overall trend toward increased interaction with the brain–cerebrospinal fluid barrier (BCSFB) after FUS-BBBO, an effect that is found to be more pronounced in the presence of disease pathology. This study addresses the prior lack of FUS neuroimmunomodulation paradigm optimization and mechanism characterization, identifying that FUS-BBBO best modulates brain macrophage response via complex redistribution.
Wideband and low profile multipolarization reconfigurable antenna based on metasurface

In this letter, a wideband and low‐profile multipolarization reconfigurable antenna based on metasurface (MTS) is proposed. The antenna mainly contains two parts, an upper layer of MTS and a bottom layer of circular slot antenna. The MTS acts as a polarization controller, by mechanically rotating the MTS layer at a proper angle while keeping the circular slot antenna remain stationary, the polarization mode of the antenna can be switched to linear polarization (LP), left‐hand circular polarization (LHCP), and right‐hand circular polarization (RHCP). The experimented −10 dB impedance bandwidth of 37.8% and 54% for LP and circular polarization (CP) modes, respectively. The measured overlapped 3‐dB AR bandwidth is 22.2% for both CP modes, covering from 3.2 to 4 GHz. Moreover, the measured peak gain of the presented antenna reaches 9 dBi and 8 dBic for LP and CP modes, with a lower profile of 0.05 λ0.

Mathematical analysis of a model for thymus infection with discrete and distributed delays

In this paper, the dynamics of mathematical model for infection of thymus gland by HIV-1 is analyzed by applying some perturbation through two different types of delays such as in terms of Hopf bifurcation analysis. Further, the conditions for the existence of Hopf bifurcation are derived by evaluating the characteristic equation. The direction of Hopf bifurcation and stability of bifurcating periodic solutions are determined by employing the center manifold theorem and normal form method. Finally, some of the numerical simulations are carried out to validate the derived theoretical results and main conclusions are included.
