Effect of Curing Modes on the Mechanical Properties of Commercial Dental Resin-Based Composites: Comparison between Different LEDs and Microwave Units

Resin-based composites (RBCs) have transformed restorative dentistry and its procedures. However, the characteristics of RBCs have been modified over the years to enhance the physical and chemical properties of the materials. This context raises the need for studies that evaluate whether the properties of the RBCs that are commercially available are clinically adequate with different curing modes. This study aimed to evaluate the mechanical behavior of commercial RBCs after undergoing different curing modes. Twenty-three RBCs of different classes were evaluated. For curing the specimens, a microwave (BMS45, Brastemp) (for 3 min at 450 W) and three LED units were used: an Emitter A Fit (Schuster (second generation)) (light-curing for 15 s with an irradiance of 1250 mW/cm2), VALO (Ultradent (third generation)) (light-curing for 15 s with an irradiance of 1100 mW/cm2), and Emitter Now Duo (Schuster (second generation)) (light-curing for 15 s with an irradiance of 1100 mW/cm2). A total of 670 RBC specimens of 8 mm in diameter and 1 mm in depth were obtained. Afterward, a biaxial flexure strength test was performed until the failure of the specimens, using a universal testing machine set at a speed of 0.5 mm/min. The same specimens were subjected to infrared spectroscopy for evaluating the degree of conversion. Tukey’s test was used for multiple comparisons at a significance level of 5%. The light-curing mode did not affect the flexure strength of the RBCs (p > 0.05), but the type and shade of RBCs did so (p < 0.05). In conclusion, the type of RBC directly interferes with the mechanical behavior of the material. However, the curing modes within the same RBC did not change the mechanical properties.
The “www” of Xenopus laevis Oocytes: The Why, When, What of Xenopus laevis Oocytes in Membrane Transporters Research

After 50 years, the heterologous expression of proteins in Xenopus laevis oocytes is still essential in many research fields. New approaches and revised protocols, but also classical methods, such as the two-electrode voltage clamp, are applied in studying membrane transporters. New and old methods for investigating the activity and the expression of Solute Carriers (SLC) are reviewed, and the kinds of experiment that are still useful to perform with this kind of cell are reported. Xenopus laevis oocytes at the full-grown stage have a highly efficient biosynthetic apparatus that correctly targets functional proteins at the defined compartment. This small protein factory can produce, fold, and localize almost any kind of wild-type or recombinant protein; some tricks are required to obtain high expression and to verify the functionality. The methodologies examined here are mainly related to research in the field of membrane transporters. This work is certainly not exhaustive; it has been carried out to be helpful to researchers who want to quickly find suggestions and detailed indications when investigating the functionality and expression of the different members of the solute carrier families.
High-energy radiation from magnetized neutron stars

The primary concern is with electromagnetic processes in the magnetospheres of neutron start, as opposed to the physics of their internal structure and evolution. The first six chapters provide a systematic coverage of plasma effects, radiation transfer, and quantum electrodynamics in strong magnetic fields. In the second half of the book, complete chapters are devoted to accreting x-ray sources in binary systems, isolated pulsars, gamma ray bursts, and the controversial extremely high-energy sources.
Premature Primary Tooth Loss and Oral Health-Related Quality of Life in Preschool Children

The present study aimed to evaluate the association between premature primary tooth loss and oral health-related quality of life (OHRQoL) in preschool children. A cross-sectional study was conducted in 769 5-year-old preschool children. The children and their parents or guardians answered the Brazilian version of the Scale of Oral Health Outcomes for 5-Year-Old Children for the assessment of OHRQoL. Meanwhile, clinical examinations were performed for the assessment of premature primary tooth loss. Unadjusted and adjusted multilevel Poisson regression models were utilized to investigate the associations between the variables. In the parental version of the scale, premature posterior primary tooth loss (rate ratio [RR] = 2.65; 95% confidence interval [CI] = 1.51–4.68), weak sense of coherence (RR = 2.25; 95% CI = 1.62–3.11), and visit to a dentist (RR = 1.61; 95% CI = 1.04–2.52) were associated with OHRQoL. Based on the children’s perceptions, only the preschool type was associated with OHRQoL (RR = 1.92; 95% CI = 1.21–3.05). Premature posterior primary tooth loss had a greater impact on OHRQoL based on the parents’ perception, whereas only the preschool type was associated with OHRQoL based on the children’s perception.
Open Research Online Stuck in the Middle? Making Sense of the Impact of Micro, Meso and Macro Institutional, Structural and Organisational Factors on Implementing Learning Analytics Conference or Workshop Item

2015), this paper provides a perspective on three levels – micro, meso and macro – of factors that shape and impact the effectiveness of learning analytics. Much of the learning analytics literature is focused on the individual student, at a micro level, and on how student characteristics and behaviours determine outcomes. This paper suggests that such a focus may be misguided. In viewing the factors which impact on student learning from a socio-critical perspective, we find that many (as identified through learning analytics and communicated to students, faculty and support staff through dashboards and early warning systems) may fall outside students’ loci of control.
Is Holographic Entropy and Gravity the result of Quantum Mechanics

In this paper we suggest a connection between quantum mechanics and Verlinde's recently proposed entropic force theory for the laws of Newton. We propose an entropy based on the quantum mechanical probability density distribution. With the assumption that the holographic principle holds we propose that our suggested quantum entropy generalizes the Bekenstein entropy used by Verlinde in his approach. Based on this assumption we suggest that Verlinde's entropic theory of gravity has a quantum mechanical origin. We establish a reformulation of the Newtonian potential for gravity based on this quantum mechanical entropy. We also discuss the notion of observation and the correspondence to classical physics. Finally we give a discussion, a number of open problems and some concluding remarks.
Development and validation of a risk prediction model for post-traumatic stress disorder symptoms in patients with acute myocardial infarction in China.

BACKGROUND At present, there are many influencing factors of post-traumatic stress disorder (PTSD) symptoms in patients with acute myocardial infarction (AMI), but based on this, there are few studies on the risk prediction model of PTSD symptoms. The aim of this study was to investigate the risk factors of PTSD symptoms in patients with AMI and to construct a risk prediction model. METHODS From April 2021 to March 2022, 287 patients were enrolled from a hospital in Shandong Province, China. According to the PTSD Checklist (PCL-C) scores 30 days after discharge, the participants were divided into a PTSD symptoms group (92 cases) and a non-PTSD symptoms group (195 cases). The demographic data, disease factors, treatment factors, and laboratory examination indicators were compared between the 2 groups; independent risk factors were screened out, and a risk prediction model was constructed by logistic regression. Area under the curve (AUC) was used as the internal verification of the model prediction. From April 2022 to June 2022, 72 patients with AMI in a hospital in Shandong Province were selected. PCL-C data were collected 30 days after discharge, and finally external validation of the model was performed. RESULTS Five factors, including gender [odds ratio (OR) =3.325], diabetes history (OR =2.292), creatine kinase isozyme (OR =1.046), insomnia score (OR =2.045), and fear of disease progression score (OR =1.126) were included to construct the risk prediction model. According to the Hosmer-Lemeshow test, P=0.785. The AUC was 0.910, the maximum value of Youden index was 0.751, the sensitivity was 0.870, the specificity was 0.881, and the accuracy rate of practical application was 67.64%. CONCLUSIONS The risk prediction model of PTSD symptoms in patients with AMI established in this study is consistent and effective. It can provide a reference for clinical assessment of PTSD symptoms risk in patients with AMI.
Minimum accelerations from quantised inertia

It has recently been observed that there are no disc galaxies with masses less than 109M⊙ and this cutoff has not been explained. It is shown here that this minimum mass can be predicted using a model that assumes that 1) inertia is due to Unruh radiation, and 2) this radiation is subject to a Hubble-scale Casimir effect. The model predicts that as the acceleration of an object decreases, its inertial mass eventually decreases even faster stabilising the acceleration at a minimum value, which is close to the observed cosmic acceleration. When applied to rotating disc galaxies the same model predicts that they have a minimum rotational acceleration, i.e.: a minimum apparent mass of 1.1×109M⊙, close to the observed minimum mass. The Hubble mass can also be predicted. It is suggested that assumption 1 above could be tested using a cyclotron to accelerate particles until the Unruh radiation they see is short enough to be supplemented by manmade radiation. The increase in inertia may be detectable.
The combinatorial theory of single-elimination tournaments

Combinatorial methods are used to generate and count the distinct tournament structures that exist. Recursive formulas are derived. Various criteria for “best” are considered. A tournament draw is said to be ordered when the probabilities of teams winning the tournament are ordered by the relative strengths of the teams. Numerous theorems are given concerning ordered tournaments, subtournaments, and “best” tournaments. The results developed apply to any number of teams, not just when the number of teams is a power of two. Assuming a transitive preference structure for the pairwise probabilities of teams beating each other, results on ordered tournaments and “best” tournaments are given, some of which make use of optimization routines on the computer. Results show that there exist categories of ordered tournaments which are best under certain criteria. It is proven that ordered tournament draws can be generated by iteratively combining subtournaments in just two specific ways.
Revealing Personality Triggers for Media Vicarious Traumatization: A Fuzzy-Set Qualitative Comparative Analysis

People may experience media vicarious traumatization due to frequent exposure to media coverage of disasters. Currently, the influential relationship between personality traits and media vicarious traumatization still lacks systematic and in-depth research. Based on the MU5735 airplane crash, this study explored the effects of configurations of personality traits on media vicarious traumatization by analyzing data from 331 Chinese university students (Mage = 22.63 years, SD = 2.67, range = 18 to 29, n = 186 male and n = 145 female) using Fuzzy-set Qualitative Comparative Analysis (fsQCA). The results revealed that five combinations of the Big Five personality traits could lead to media vicarious traumatization, the combinations of configurations are: (1) high conscientiousness, high agreeableness, and high neuroticism; (2) high conscientiousness, high extraversion, and high agreeableness; (3) high extraversion, high neuroticism, low conscientiousness, and low agreeableness; (4) high openness, high extraversion, high agreeableness, and high neuroticism; (5) high extraversion, high agreeableness, low openness, and low neuroticism. Furthermore, sociodemographic variables (gender, age, and education) interacted with personality traits and also resulted in different configurations of media vicarious traumatization. This study indicates the asymmetric relationships between personality traits and media vicarious traumatization, identifies the vulnerable groups to facilitate targeted trauma interventions for university students according to different configurations, and provides a reference for public psychological relief efforts in emergencies.
Prostate Cancer-Associated miRNAs in Saliva: First Steps to an Easily Accessible and Reliable Screening Tool

Background: Common diagnostic tools for prostate cancer—prostate-specific antigen and transrectal biopsy—show only low predictive value and poor sensitivity. This study examines circulating miRNA in saliva to explore the possibility of a non-invasive and easy-to-execute diagnostic tool for prostate cancer screenings. Methods: 16 miRNAs were extracted from salivary exosomes and analyzed via the delta-CT method. The presented method enables an application of the test in any health institution and even outpatient sector. Recruited participants were suspected to suffer from prostate cancer due to elevated PSA serum levels. Of these participants, 43 were diagnosed with prostate cancer, while 31 suffered from benign diseases and served as control group. Results: hsa-mir-331-3p and hsa-mir-200b were significantly reduced in prostate cancer patients compared to the control group. ROC curve analysis revealed a reliable differentiation strength (AUC > 0.6) for both miRNAs with positive predictive values of 71% indicating prostate cancer. Differentiation of both groups based on PSA serum measurements was insufficient. The other 14 examined miRNAs showed no significant group differences. Conclusions: The presented method and miRNA are promising non-invasive tools to augment the current prostate cancer screening, thereby improving screening sensitivity and reducing numbers of false positive cancer suspects admitted to further invasive diagnostic and therapeutic steps.
Formulation and Evaluation of Diclofenac Potassium Gel in Sports Injuries with and without Phonophoresis

Background: Pain remains a global public heath priority. Phonophoresis, also known as sonophoresis or ultrasonophoresis, is when an ultrasound is used to maximize the effects of a topical drug. Purpose: The objective of this study was to test, in patients injured in sports or accidents (N = 200), the efficacy of diclofenac potassium (DK) 6%, 4%, and 2% formulated gels with and without phonophoresis in comparison with market available standard diclofenac sodium (DS or DN) gel. Methods: The patients were enrolled after informed consent. By using the lottery method, 100 patients were randomly segregated into five groups without phonophoresis and repeated similarly with phonophoresis at a frequency of 0.8 MHz, an intensity of about 1.5 W/cm2, and at continuous mode (2:1). Group-1 was treated with 6% DK gel, group-2 was treated with 4% DK gel, group-3 was treated with 2% DK gel, group-4 was treated with 4% DS gel and group-5 was given control gel three to four times a week for 4 weeks. The patients were screened by using NPRS and WOMAC scales. They were assessed on the baseline, 4th session, 8th session, 12th session, and 16th session. Results: Significant dose-dependently relief was observed in NPRS (Numeric Pain Rating Scale) and the WOMAC (Western Ontario McMaster Osteo-Arthritis) index for pain in disability and stiffness for each group treated with DK gel compared to DS gel. Phonophoresis increased these benefits significantly when used after topical application of DK gel or DS gel, and the dose-dependent effects of DK gel plus phonophoresis were stronger than the dose-dependent effects of DS gel plus phonophoresis. The faster and profounder relief was due to phonophoresis, which allows more penetration of the DK gel into the skin as compared to the direct application of DK gel in acute, uncomplicated soft tissue injury, such as plantar fasciitis, bursitis stress injuries, and tendinitis. In addition, DK gel with phonophoresis was well tolerated. Thus, in this personalized clinical setting, according to the degree of inflammation or injured-induced pain, disability, and stiffness, DK gel 6% with phonophoresis appeared more effective and thus more recommendable than DS gel 6% alone or DS gel 6% combined to phonophoresis.
Association between serum irisin concentration and ischemic stroke: From etiology to clinic

Background To investigate the relationship between irisin levels in serum and classification of subtype of acute ischemic stroke, National Institutes of Health Stroke Scale (NIHSS) and Modified Rankin Score (mRS) at the time of discharge from the hospital in Turkish patients who had their first acute ischemic stroke (AIS). Methods Serum irisin levels were measured using enzyme linked immunosorbent assay (ELISA) 180 patients who applied to emergency department with the diagnosis of AIS from May 2021 to November 2021. Results A significant relationship was found between serum irisin levels and ischemic stroke aetiological factors (TAOST) (p=0.017). Increased serum irisin levels were detected in patients without neurological deficits with localization value than those with it (p<0.01). Serum irisin levels also have a negative correlation with high-density lipoprotein (HDL) value in ischemic stroke (r: -0.272, p<0.01). Conclusions High serum irisin levels found in patients with stroke attributed to small vessel disease and in patients with ischemic stroke in whom we did not find any neurological deficits with a localization value. The results of the study show that serum irisin levels have an important role in the etiology of ischemic stroke. Although the question how the irisin is involved in the course of ischemic stroke and what the clinical reflection has not been answered, these findings are a pioneering study on this subject.
Logarithmic forms and group varieties.

The past decade has seen some spectacular progress concerning multiplicity estimates on group varieties. The first substantial work in this context is due to Masser and Wüstholz [18]; they considered a single differential operator on such a variety and their results led, amongst other things, to the new theory of large transcendence degree. One of the main ingredients was the use of effective commutative algebra which was introduced into the subject by Nesterenko [20] through the study of . E-functions and which was subsequently extended by Brownawell and Masser [10]. In 1983, Wüstholz [29] succeeded in obtaining a general theorem on multiplicity estimates appertaining to arbitrarily many differential operators and, up to a constant multiple, the results are best possible. The work has already found application to yield an abelian analogue of the famous Lindemann theorem and to solve a long-standing problem concerning periods of elliptic integrals (see [26], [27], [28]). The key result in this context is now the analytic subgroup theorem established in Wüstholz [30] which includes äs special cases most of the classical theorems in transcendence theory. In particular it furnishes a generalisation in terms of algebraic groups of the qualitative Version of Baker's theorem on linear forms in the logarithms of algebraic numbers.
A CATALOG OF BULGE+DISK DECOMPOSITIONS AND UPDATED PHOTOMETRY FOR 1.12 MILLION GALAXIES IN THE SLOAN DIGITAL SKY SURVEY

We perform two-dimensional, point-spread-function-convolved, bulge+disk decompositions in the g and r bandpasses on a sample of 1,123,718 galaxies from the Legacy area of the Sloan Digital Sky Survey Data Release Seven. Four different decomposition procedures are investigated which make improvements to sky background determinations and object deblending over the standard SDSS procedures that lead to more robust structural parameters and integrated galaxy magnitudes and colors, especially in crowded environments. We use a set of science-based quality assurance metrics, namely, the disk luminosity–size relation, the galaxy color–magnitude diagram, and the galaxy central (fiber) colors to show the robustness of our structural parameters. The best procedure utilizes simultaneous, two-bandpass decompositions. Bulge and disk photometric errors remain below 0.1 mag down to bulge and disk magnitudes of g ≃ 19 and r ≃ 18.5. We also use and compare three different galaxy fitting models: a pure Sérsic model, an nb = 4 bulge + disk model, and a Sérsic (free nb) bulge + disk model. The most appropriate model for a given galaxy is determined by the F-test probability. All three catalogs of measured structural parameters, rest-frame magnitudes, and colors are publicly released here. These catalogs should provide an extensive comparison set for a wide range of observational and theoretical studies of galaxies.
Multinationals and Structural Transformation

We study the role of multinationals (MNCs) in facilitating firm-level and aggregate structural transformation. Using a stylized model of multinational production and trade, we show that an inward multinational liberalization in the manufacturing sector raises employment in host country firms, and decreases manufacturing employment, while also raising services employment, in the parent firms. We also show the conditions under which aggregate structural transformation occurs. We test the models firm-level predictions by using confidential microdata from Japan. We study the response of Japanese MNC parents and their affiliates in China to an exogenous change in China's openness to foreign direct investment (FDI). We find that in industries where inward FDI was encouraged, Japan MNCs' affiliates in China experienced increases in their employment. We also find that MNC parents in the encouraged industries experienced decreases in home country manufacturing employment and increases in home country services and R&D employment. Finally, using microdata for several advanced and middle-income countries, we decompose the change in overall manufacturing employment shares into MNC and non-MNC components. We find a significant role for MNCs across all countries, suggesting the mechanism we highlight is an important global driver of structural transformation.
Mobile Device Camera Calibration Using Building Images and Onboard Accelerometer

Recent mobile devices are mostly integrated with cameras and accelerometer sensors. As long as the device is immobile, the accelerometer is affected just by gravity, hence the measured acceleration refers to gravity. On the other hand, synchronized captured images can also carry the direction of gravity information depending on the content of the scene. For instance, structures such as buildings, lighting poles, furniture, walls, and so on can show the direction of gravity in the images. These vertical structures in the image can be used to detect the vanishing point indicating the zenith. Hence, estimation of the camera internal parameters which map gravity vector into the vanishing point is possible. Based on this theory, in this work, we propose a novel camera calibration method that only requires taking photos of an arbitrary building and recording the synchronous acceleration vectors from an onboard accelerometer. Then, the vanishing points detected from the images and the acceleration vectors replace the 3-D calibrator. The resulting camera calibration method has competitive results compared to the popular calibrator-based methods despite it does not need any external calibrator object. The proposed camera calibration method both has the convenience of self-calibration approaches and gives highly competitive accuracy within calibrator-based approaches. The dataset and the code are available at https://github.com/okayarik/Camera-Calibration-Using-Accelerometer.
