Evaluation of the Effect of Dental Anxiety on the Quality of Life of the Patients

Background: Oral health-related quality of life is a concept that reveals how problems occurring in the social, physical, psychological, and orofacial areas affect the well-being of the person. Objectives: In this study was aimed to determine the relationship between dental anxiety and oral health-related quality of life of patients. Methods: In a descriptive study, a quantitative research approach was used. We reached 258 patients who came to the Endodontics and Prosthodontics clinic. Data were obtained by using the “dental anxiety (M-DAS) and quality of life (OHIP-14) scale together with the demographic questionnaire. Results: The mean score the patients got from M-DAS was 11.68 ± 4.41; the average score of OHIP-14 was determined as 16.72 ± 10.89. It was determined that there is a strong negative correlation between total M-DAS and total OHIP-14 scores. The patients stated that they most frequently experienced problems in terms of physiological limitation in OHIP-14 questions. Conclusions: The quality of life associated with oral health decreases for individuals with high levels of dental anxiety. In order to increase the quality of life-related to oral health, it is necessary to reduce the level of anxiety about the teeth and improve oral health at regular dental visits
Comparison of Serum Calcium Level in Preeclamptic and Normotensive Pregnant Women in Nigeria

Background: Pre-eclampsia is often referred to as disease of theories as the precise factors involved in its pathogenesis are unclear. While alterations in calcium metabolism have been linked with preeclampsia, the role of calcium in the development of the disease remains uncertain. Objectives: This study aimed to compare the clinical features and serum calcium levels of preeclamptic women with normotensive controls. Patients and methods: The study was a case-control study among patients with pre-eclampsia and healthy normotensive women. Results: Ninety-five preeclamptic patients and 95 matched controls participated in the study. More than half (61.1%) of the pre-eclamptic women were unbooked while only about one-third (30.5%) of the normotensive women were unbooked (P<0.001). Pre-eclamptic women had significantly shorter duration of cohabitation with biological fathers of their foetuses than the normotensive controls. Pre-eclamptic patients were thrice more likely to have family history of hypertension than the control group (14.7% vs 4.2% P=0.013). Similarly, the mean serum calcium levels were statistically significantly lower in preeclamptic patients (1.87± 0.27 mmol/L) compared to the pregnant normotensive controls (2.33±0.28 mmol/L). Conclusion: Serum calcium levels were significantly lower in pre-eclamptic women compared to the normotensive controls in the
Integrated Bi-Manual Motion Generation and Control shaped for Probabilistic Movement Primitives

This work introduces a novel cooperative control framework that allows for real-time reactiveness and adaptation whilst satisfying implicit constraints stemming from proba-bilistic/stochastic trajectories. Stemming from task-oriented sampling and/or task-oriented demonstrations, e.g., learning based on motion primitives, such trajectories carry additional information often neglected during real-time control deployment. In particular, methods such as probabilistic movement primitives offer the advantage to capture the inherent stochasticity in human demonstrations - which in turn reflects human's understanding about task-variability and adaption possibilities. This information, however, is often poorly exploited and, mostly, used during offline trajectory planning stage. Our work instead introduces a novel real-time motion-generation strategy that explicitly exploits such information to improve trajectories according to changes in the environmental condition and robot task-space topology. The proposed solution is particularly well-suited for bi-manual and coordinated systems where the increased kinematic complexity, tightly-coupled constraints and reduced workspace have detrimental effects on the manipula-bility, joint-limits, and are even capable of causing unstable behavior and task-failure. Our methodology addresses these challenges, and improves performance and task-execution by taking the confidence range region explicitly into account whilst maneuvering towards better configurations. Furthermore, it can directly cope with different closed-chain kinematics and task-space topologies, resulting for instance from different grasps. Experimental evaluations on a bi-manual Franka panda robot show that the method can run in the inner control loop of the robot and enables successful execution of highly constrained tasks.
Comparison of two possible dynamic models for gear dynamic analysis

Several gear dynamics models are available in literature, each with its unique application. In this paper a comparison between two models will be discussed. While the source of excitation in both models will come from the time varying mesh stiffness caused by the static transmission error the first model aims to estimate the dynamic overloads due to the meshing with a simple one-dimensional approach, neglecting other flexibilities. The second one instead includes the flexibilities of the shafts as well as bearings and the gearbox housing, with the possibility of being extended to multistage transmissions. Both models are quick and can give useful insight in the design process of a geared transmission. A simple test case will be detailed highlighting the different capabilities of the models and providing several key results such as dynamic forces and displacements which can help designers to define better components.
Oxidative Potential in Exhaled Air (OPEA) as a Tool for Predicting Certain Respiratory Disorders in the General Adult Population: Cross-Sectional Analysis Nested in the Swiss Health Study

In a pilot clinical study, OPEA allowed for distinguishing participants with and without chronic obstructive pulmonary disease. This study aimed to assess whether abnormal spirometry parameters and immunity against SARS-CoV-2 are associated with increased OPEA and estimating the OPEA reference interval. Swiss adult residents of the Vaud Canton aged 20–69 years randomly selected from the Federal Statistical Office’s registries, speaking French or German, were included and examined between 1 October 2020 and 31 December 2021. General health status and presence of respiratory diseases were assessed by questionnaire and spirometry. Spirometric results were compared with the predicted values and their lower limits of norms of the Global Lung Function Initiative. SARS-CoV-2-seroprevalence was assessed using the Luminex-based test of IgG. Statistical analysis consisted of unilateral t-tests and ANOVA. Lower and upper limit of OPEA reference interval with associated 90%-confidence interval (90%CI) were estimated for the sub-sample of healthy adults by bootstrap, after excluding outliers. The study sample included 247 participants. SARS-CoV-2-seropositive participants and those with an obstructive syndrome had a significantly higher OPEA than seronegative and healthy participants. The estimated reference interval was: −0.0516 (90%CI = −0.0735; −0.0316); −0.0044 (90%CI = −0.0224; 0.0153). OPEA could predict inflammatory-based respiratory disorders, but needs further validation in different settings and for other pathologies.
Case Report Delirium Induced by Perindopril: A Case Report

Perindopril is a commonly prescribed angiotensin converting enzyme inhibitor because of its safety and efficacy [1]. Some of ACE inhibitors can cross blood brain barrier, and have the ability to cause neuropsychiatry effects [2]. Risk factors for ACE inhibitors-induced delirium include advanced age and underlying neuropsychiatry disorders [3]. In this case report, we present a case of a patient with delirium caused by perindopril.
The anticancer effects induced by the bacterial protein azurin: evaluation of cytotoxicity, membrane destabilization and cell death in multiple cancer cell models

Azurin is a protein secreted by the bacterium Pseudomonas aeruginosa which has been studied as an anticancer agent. This exploratory work aims to contribute to the elucidation of the extent of cell proliferation inhibition, membrane disruption and cell death in multiple cancer cell lines (HeLa, cervix adenocarcinoma; AGS, gastric adenocarcinoma; and U2OS, osteosarcoma) upon treatment with azurin. In order to ascertain cell proliferation MTT assays were performed. To measure membrane disruption and cell death PI-FL3 flow cytometry was employed (with non-fixed and fixed cells, respectively). After 72 h exposure to treatment (100 µM azurin), all cancer cell lines showed a dose dependent proliferation inhibition regardless of p53 status with IC50 roughly estimated to be around 140 µM for HeLa, 75 µM for AGS and 70 µM for U2OS. Azurin contributed to the destabilization of the cell membrane upon long exposures (72 h) with 16.4±6.4% (HeLa), 45.9±5.0% (AGS), 19.9±10.6% (U2OS) and 10.3% * (BHK, non-tumorigenic fibroblast cell line) propidium iodide (PI) permeable populations. This destabilization was superior relative to the observed cell death, with HeLa, AGS, U2OS cells presenting 6.9±3.2%, 14.9±4.6%, 6.8±3.9% hypoploid populations, respectively, (corresponding to dead cells with fragmented DNA) upon treatment with 100 μM at 72 h of azurin WT against the 4.6±0.8% hypoploid population in BHK cells. Thus, in this work it was observed that azurin has an anti-proliferative (cytostatic) effect in the tested cell lines with apparent membrane disruption in the population. Although present, azurin appears to have limited cytotoxic effects by itself and, given its diffuse mode of action, it seems more reasonable to use azurin as a co-adjuvant with a synergistic effect, in order to enhance the efficacy of other anti-cancer drugs and possibly to surpass multidrug resistance events, rather than as a standalone therapeutic. bioengineering of truncation products and
On central stability

The notion of central stability was first formulated for sequences of representations of the symmetric groups by Putman. A categorical reformulation was subsequently given by Church, Ellenberg, Farb, and Nagpal using the notion of FI‐modules, where FI is the category of finite sets and injective maps. We extend the notion of central stability from FI to a wide class of categories, and prove that a module is presented in finite degrees if and only if it is centrally stable. We also introduce the notion of d ‐step central stability, and prove that if the ideal of relations of a category is generated in degrees at most d , then every module presented in finite degrees is d ‐step centrally stable.
Aerodynamic Loss in a Linear Turbine Cascade with Tip Clearance and Upstream Casing Coolant Injection

This study describes the effect of casing coolant injection on aerodynamic loss in a linear turbine cascade with tip clearance. Four test cases with and without tip clearance and casing coolant injection are compared for this study. The mass flow rate and the non-dimensional swirl of the coolant are 0.5% of the main flow and 100% of the blade tip velocity respectively. Regardless of the presence of the tip clearance, casing coolant injection increases losses associated with the passage vortex and the trailing shed vortex and move their spanwise locations toward midspan. The loss near the casing without tip clearance increases significantly with casing coolant injection. However, in the casing with tip clearance, the loss near the casing is slightly decreased by the casing coolant injection. With casing coolant injection, tip clearance flow is reduced, and the loss associated with the tip clearance vortex decreases. Without tip clearance, the mass-averaged loss increases by 53.9% with casing coolant injection. However, with tip clearance, the loss increases by 15.9%.
Proton-nucleus elastic scattering: Comparison between phenomenological and microscopic optical potentials

Elastic scattering is a very important process to understand nuclear interactions in finite nuclei. Despite decades of efforts, the goal of reaching a coherent description of this physical process in terms of microscopic forces is still far from being completed. In previous papers (Phys. Rev. C93, 034619 (2016), Phys. Rev. C96, 044001 (2017)) we derived a nonrelativistic theoretical optical potential from nucleon-nucleon chiral potentials at fourth (N3LO) and fifth order (N4LO). We checked convergence patterns and established theoretical error bands. With this work we study the performances of our optical potential in comparison with those of a successful nonrelativistic phenomenological optical potential in the description of elastic proton scattering data on several isotopic chains at energies around and above 200 MeV. We use the same framework and the same approximations of our previous papers, where the nonrelativistic optical potential is derived at the first-order term within the spectator expansion of the multiple scattering theory and adopting the impulse approximation and the optimum factorization approximation. The cross sections and analyzing powers for elastic proton scattering off calcium, nickel, tin, and lead isotopes are presented for several incident proton energies, exploring the range $156 \le E \le 333$ MeV, where experimental data are available. In addition, we provide theoretical predictions for Ni56 at 400 MeV, which is of interest for the future experiments at EXL. Our results indicate that microscopic optical potentials derived from nucleon-nucleon chiral potentials at N4LO can provide reliable predictions for the cross section and the analyzing power both of stable and exotic nuclei, even at energies where the reliability of the chiral expansion starts to be questionable.
Best-Response Dynamics in the Boston Mechanism

I analyze a setting where the Boston Mechanism (BM) is applied repeatedly and students form their application strategies by best-responding to the admission cutoﬀs of the previous period, a process I call the Repeated Boston Mechanism (RBM). If students are truthful in the initial period, the allocation under RBM converges in ﬁnite time to the student optimal stable matching (SOSM), which is the Pareto-dominant equilibrium of BM and the outcome of the strategy-proof Deferred Acceptance Mechanism. If some students are sincere and do not strategize, then the allocation under RBM with sincere students converges to the SOSM of a market in which sincere students lose their priorities. When students best-reply to some initial cutoﬀs in the ﬁrst period, RBM converges to SOSM if students are initially optimistic about their admissions chances but may cycle between allocations Pareto-dominated by SOSM if they are pessimistic. My results provide a foundation for equilibrium analysis under BM and help explain why students play suboptimal and overcautious strategies.
Context-Aware Navigation Protocol for Safe Driving in Vehicular Cyber-Physical Systems

A connected network of automated vehicles on roads can increase the driving safety of driverless vehicles (i.e., autonomous vehicles). The critical level of dangerous situations on the road while driving can be increased by the speed, orientation, and traffic density of the vehicles involved. Therefore, there is a need for a maneuvering mechanism that handles both the current driving vehicle and the oncoming vehicles headed toward an emergency zone (e.g., road hazard and road accident spot). In this paper, we present a context-aware navigation protocol (CNP) that enhances the safety of vehicles driving in urban roads. Firstly, CNP includes a collision avoidance module that builds on both vehicular networks and on-board sensors to track vehicles’ behaviors, and this module analyzes the driving risks to determine the necessary maneuvers in dangerous situations. Secondly, CNP establishes a collision mitigation strategy that limits the severity of collision damages in hazardous road during non-maneuverable scenarios. We conducted a theoretical analysis as well as extensive simulations to prove and evaluate the effectiveness of CNP. The results show that CNP can reduce communication overhead from a baseline scheme by up to 60% while the risk of road collisions is less than 5%.
The Evolving Luminosity Function of Red Galaxies

We trace the assembly history of red galaxies since z = 1 by measuring their evolving space density with the B-band luminosity function. Our sample of 39,599 red galaxies, selected from 6.96 deg2 of imaging from the NOAO Deep Wide-Field Survey and the Spitzer IRAC Shallow Survey, is an order of magnitude larger, in size and volume, than comparable samples in the literature. We measure a higher space density of z ~ 0.9 red galaxies than some of the recent literature, in part because we account for the faint yet significant galaxy flux that falls outside of our photometric aperture. The B-band luminosity density of red galaxies, which effectively measures the evolution of ~L* galaxies, increases by only 36% ± 13% from z = 0 to z = 1. If red galaxy stellar populations have faded by ≃1.24 B-band magnitudes since z = 1, the stellar mass contained within the red galaxy population has roughly doubled over the past 8 Gyr. This is consistent with star-forming galaxies being transformed into ≲L* red galaxies after a decline in their star formation rates. In contrast, the evolution of ≃4L* red galaxies differs only slightly from a model with negligible z < 1 star formation and no galaxy mergers. If this model approximates the luminosity evolution of red galaxy stellar populations, then ≃80% of the stellar mass contained within today's 4L* red galaxies was already in place at z = 0.7. While red galaxy mergers have been observed, such mergers do not produce rapid growth of 4L* red galaxy stellar masses between z = 1 and the present day.
Turkish Preservice Primary School Teachers' Science Teaching Efficacy Beliefs and Attitudes toward Science: The Effect of a Primary Teacher Education Program.

The main purpose of this study was to investigate the effectiveness of a primary teacher education program in improving science teaching efficacy beliefs (personal science teaching efficacy beliefs and outcome expectancy beliefs) of preservice primary school teachers. The study also investigated whether the program has an effect on student teachers' attitudes toward science. Data were collected by administering the “Science Teaching Efficacy Beliefs Instrument” and “Attitudes toward Science Scale” to 282 preservice primary teachers (147 freshmen, 135 seniors). Statistical techniques such as means and t-test were used to analyze the data. Results of the study showed that the primary teacher education program has a medium positive effect on science teaching efficacy beliefs of the primary preservice teachers (t = 4.791, p = .000) and that there were no gender differences in terms of efficacy beliefs. Results also indicated that preservice primary teachers' attitudes toward science were moderately positive and differ by class level. Fourth-year preservice teachers' attitudes toward science were found to be significantly more positive than the first years (t = 5.494, p = .000). There were no gender differences in attitudes toward science.
The Physical Origin of Long Gas Depletion Times in Galaxies

We present a model that explains why galaxies form stars on a timescale significantly longer than the timescales of processes governing the evolution of interstellar gas. We show that gas evolves from a non-star-forming to a star-forming state on a relatively short timescale, and thus the rate of this evolution does not limit the star formation rate (SFR). Instead, the SFR is limited because only a small fraction of star-forming gas is converted into stars before star-forming regions are dispersed by feedback and dynamical processes. Thus, gas cycles into and out of a star-forming state multiple times, which results in a long timescale on which galaxies convert gas into stars. Our model does not rely on the assumption of equilibrium and can be used to interpret trends of depletion times with the properties of observed galaxies and the parameters of star formation and feedback recipes in simulations. In particular, the model explains how feedback self-regulates the SFR in simulations and makes it insensitive to the local star formation efficiency. We illustrate our model using the results of an isolated L*-sized galaxy simulation that reproduces the observed Kennicutt–Schmidt relation for both molecular and atomic gas. Interestingly, the relation for molecular gas is almost linear on kiloparsec scales, although a nonlinear relation is adopted in simulation cells. We discuss how a linear relation emerges from non-self-similar scaling of the gas density PDF with the average gas surface density.
Effect of droplet superficial velocity on mixing efficiency in a microchannel

In this study, droplet characteristics including droplet length and formation time, and mixing efficiency in droplets were investigated via the volume of fluid (VOF) method coupled with a user defined scalar (UDS) model. A cross-shaped junction with a square cross-section was designed and used for droplet formation. An initial arrangement which differed from that of a conventional operation was adopted. Results show that when the droplet superficial velocity is constant, the exchange between the dispersed phase velocity and the continuous phase velocity has a marginal effect on the droplet formation time. However, the exchange has a great effect on droplet length. These findings provide a valuable guide for future operation of droplet formation. In addition, the results show that the mixing efficiency in the droplet forming stage can be classified into time-dominated and length-dominated regimes according to the droplet superficial velocity. When a droplet flows in a microchannel, a higher droplet superficial velocity increases mixing efficiency due to the faster inner circulation and shorter droplet length.
Current Sheets in the Wake of an Eruption of Two Crossing Filaments

Employing Solar Dynamic Observatory/Atmospheric Imaging Assembly (AIA) multi-wavelength images, we study an eruption of two crossing filaments, and report for the first time the current sheets (CSs) connecting the lower flare ribbons and the upper erupting filaments. On 2014 July 8, two crossing filaments are observed in the NOAA active region 12113. The lower-lying filament rises first, and then meets the higher-lying one. Thereafter, both of them erupt together. The filament eruption draws the overlying magnetic field lines upward, leading to the approach of two legs, with opposite magnetic polarities, of the overlying field lines. Two sets of bright CSs form at the interface of these two legs, and magnetic reconnection takes place in the CSs producing the underneath flare ribbons and post-flare loops. Several bright plasmoids appear in the CSs, and propagate along the CSs bidirectionally. The CSs and plasmoids are observed in AIA multi-wavelength channels, indicating that both of them have been heated during the reconnection process, with hot and warm components. Employing the differential emission measure (EM) analysis, we find that both the temperature and EM of the CSs decrease from the flare arcades outward to the erupting filaments, and those of the plasmoids are significantly larger than the regions where no plasmoid is detected.
